Clinical outcomes and prognostic factors in patients with nasolacrimal duct obstruction or stenosis using dacryoendoscopy.

To evaluate the effectiveness of dacryoendoscopic-assisted laser dacryoplasty with silicone intubation (DLDI) for the management of nasolacrimal duct obstruction (NLDO) or stenosis, and to identify the factors associated with DLDI failure. This study was designed as a prospective, single-centre cohort study. Patients with NLDO or stenosis who underwent DLDI from December 2019 to December 2021 at Tianjin Eye Hospital were considered for enrolment. The Kaplan-Meier estimator was used to assess the anatomical and functional success rate of DLDI within 2 years follow-up after removal of the silicone stent. Cox proportional hazards regression models were used to identify risk factors for treatment failure. 170, 174 and 178 eyes were included in Groups A (proximal NLDO), B (distal NLDO) and C (nasolacrimal duct stenosis), respectively. The overall anatomical success rate was 84.8% for the entire cohort at the 2-year follow-up. The cumulative anatomical or functional success rate for Groups B and C was significantly higher than that for Group A. In the multivariable model, a higher risk of failed DLDI surgery was associated with a history of chronic dacryocystitis (HR=3.07; p<0.001) and a longer duration of epiphora than 1 year (HR=2.67; p<0.001). Of the 522 eyes, 37 patients (7.1%) had surgery-related complications. DLDI is an effective minimally invasive technique for treatment in patients with distal NLDO or stenosis. Factors associated with a higher risk of reoperation include a longer duration of epiphora and a history of chronic dacryocystitis. NCT05999058.

The Wisconsin silicone oil study (report #1): anatomical and functional outcomes of repair of retinal detachment with proliferative vitreoretinopathy.

Silicone oil (SO) is a long-term tamponade for repair of complex retinal pathology but has limitations including late redetachment. This study describes our experience with SO tamponade for repair of retinal detachment with proliferative vitreoretinopathy (PVR), with attention to anatomic and functional outcomes. Retrospective consecutive case series of eyes with retinal detachment (RD) complicated by proliferative vitreoretinopathy (PVR) receiving SO tamponade at the University of Wisconsin between 2013 and 2019. Group 1 defined as primary SO placement; Group 2 had SO placed after failing prior retinal detachment repair. Inclusion criteria of SO placement for repair of RD with PVR was met for 117 eyes. The final reattachment rate was 84% for all eyes, with no difference between Groups 1 and 2. Vision improvement was 2.1 lines for Group 1 (p = 0.06 from baseline) and 4.6 lines for Group 2 (p < 0.0001). The mean number of silicone oil placements was 1.4. Less improvement in vision was noted with repeat SO placement, though overall functional vision of 5/200 or better was achieved in 63.2% of patients. SO tamponade allows long-term anatomical stabilisation and substantial vision recovery in eyes with retinal detachment complicated by PVR. Rates of anatomic and functional success have improved significantly when compared to prior studies using oil tamponade for repair of PVR.

Management of adult focal nasolacrimal duct stenosis: long-term outcomes of 3D CT-DCG-assisted and endoscopically guided coronary catheter balloon dacryoplasty.

The purpose was to evaluate the use of 3D CT-DCG-assisted and endoscopically guided coronary catheter balloon dacryoplasty (CC-BDCP) in adults with focal stenosis of the nasolacrimal duct (NLD) and report their long-term outcomes. A prospective, non-randomized, single-center clinical study was performed, and the patients underwent endoscopy-guided CC-BDCP using percutaneous transluminal coronary angioplasty (PTCA) balloon catheters. 25 patients were enrolled in the study. The CC-BDCP procedure was performed in 21 of 25 (84%) patients, and the remaining 4 (16%) patients had significant procedural difficulties due to unfavorable anatomical conditions. Of the 21 patients, 10 (47.6%) were procedurally assessed as "easy" (eCC-BDCP) and in 11 (52.4%) as procedurally "difficult" (dCC-BDCP). Values on Munk's epiphora intensity scale changed overall from 4.0 preoperatively to 1.4 ± 1.6 (p = 0.00001) postoperatively overall. FDDT changed overall from 2.9 ± 0.3 to 1.1 ± 1.2 after treatment (p = 0.00008) (from 2.8 ± 0.4 to 0.3 ± 0.6 in the eCC-BDCP group and from 2.9 ± 0.3 to 1.4 ± 1.2 in the dCC-BDCP group (p = 0.01352). The anatomical and functional success rate was 77% overall, 90% in the eCC-BDCP group, and 64% in the dCC-BDCP group. The CC-BDCP led to a statistically significant decrease in epiphora in a particular group of adult patients with demonstrable focal stenosis of the NLD.

Clinical Outcomes of Stage 2 (Pivotal) Use of a Modified Keratoprosthesis Device (ORC-KPro) in Patients with End-stage Corneal Blindness.

To investigate the short-term results and performance of a modified Boston keratoprosthesis device manufactured by the Ophthalmic Research Center (ORC-KPro) in patients with end-stage corneal blindness. This prospective interventional case series was conducted on patients with corneal blindness who were candidates for KPro. The inclusion criterion comprised patients with a best-corrected visual acuity (BCVA) of less than 20/200 in both eyes, in whom the main reason for vision loss was corneal pathology. The ORC-KPro was implanted using the method previously described for Boston KPro. This study focused on 12 eyes of 12 patients with an average age of 45.9 16.8 (range, 19 to 70) years. Eleven patients were male. The KPro indication was corneal blindness due to chemical burns in nine patients (75%) and failure of multiple previous corneal grafts in three patients (25%). Anatomical success was achieved in all patients. The preoperative BCVA was light perception (LP) in 10 eyes and hand motion in 1 eye. Except for one patient who was diagnosed with grade C proliferative vitreoretinopathy during the surgery, the vision of all other patients (91.6%) improved after surgery. The retroprosthetic membrane (RPM) was formed in two eyes (18.1%) after six months. Of the 12 patients, 10 (83.3%) were under treatment with two antiglaucoma medications before surgery. The intraocular pressure of three eyes (25%) was estimated to be high by tactile palpation; however, it decreased in two eyes to the acceptable range. One patient underwent retinal surgery due to total retinal detachment, and two patients (16.7%) underwent vitrectomy due to endophthalmitis. The current study showed that, in the short term, the use of ORC-KPro achieved favorable anatomical success in patients with corneal blindness. However, the functional success rate was limited by the low visual potential due to advanced glaucoma in most patients.

Efficacy and safety of a novel polytetrafluoroethylene-coated self-expandable metal stent for distal malignant biliary obstruction.

Stent migration and sludge formation remain significant problems associated with covered self-expandable metal stents (CSEMSs). The EGIS biliary stent fully covered flare type (EGIS biliary stent), a new type of polytetrafluoroethylene-coated self-expandable metal stent with low axial force and an anti-migration system, was developed to overcome these disadvantages. We conducted this study to evaluate the efficacy and safety of this stent in comparison with conventional CSEMS (c-CSEMS). We retrospectively analyzed consecutive patients with unresectable pancreatic cancer who received initial CSEMS for distal malignant biliary obstruction. The primary outcome was time to recurrent biliary obstruction (RBO). Secondary outcomes included technical success rate, functional success rate, stent-related adverse events, causes of RBO, and re-intervention. A total of 40 patients were included (EGIS group: 20; c-CSEMS group: 20). The technical and functional success rates were similar between the two groups. Stent-related adverse event rates (20% vs. 15%, p > 0.99) and overall RBO rates (56% vs. 50%, p > 0.99) were not significantly different between the two groups. Stent migration was the most common cause of RBO in the EGIS group, while stent occlusion was in the c-CSEMS group. The median time to RBO (102 vs. 434 days, p = 0.10) was not significantly different between the two groups. Endoscopic transpapillary re-intervention was successful in most patients in both groups. The EGIS biliary stent was not associated with a longer time to RBO compared to c-CSEMS. Further improvements, especially against stent migration, are needed to improve its efficacy.

Tympanic Cavity Packing in Tympanoplasty Type 1: A Meta-Analysis.

Packing of tympanic cavity is generally considered an essential step in myringoplasty. However, each packing material comes with one or another side effect. The objective of this meta-analysis was to compare the results of Type 1 myringoplasty with or without packing. Pubmed, Cochrane database, Embase, Google Scholar, and clinicaltrials.gov were searched using 'tympanoplasty or myringoplasty and packing' as the search query. All RCTs / quasi-RCTs comparing tympanoplasty Type 1 with packing (control) versus without packing (intervention) of tympanic cavity in the human population were included. For dichotomous and continuous outcomes, relative risks (RR) and mean differences (MD) were calculated with 95% confidence interval, respectively. Heterogeneity was assessed using I2 statistics. Publication bias was checked using funnel plot and Egger's test, if applicable. Quality of evidence was assessed for each outcome using GRADE approach. Eleven studies were deemed eligible. For graft uptake and functional success rate, RR of 1.01 and 1.05 were obtained, respectively, showing no significant differences between the intervention and control groups. At 1st and 3rd postoperative month, no-packing group showed 3.86 dB and 2.08 dB better air-bone gap (ABG) closure than the packing group, respectively. Also, intervention with no-packing was 9.28-minute shorter procedure. With RR 0.35, no-packing had significantly lesser postoperative aural fullness. Type 1 tympanoplasty performed with or without packing show comparable results in terms of graft uptake and functional success rate. However, if performed without packing, it takes shorter time, provides early hearing improvement and causes less aural fullness. Key Words: Tympanoplasty Type 1, Packing, Gelfoam, No-packing, Meta-analysis, Endoscopic myringoplasty.

Sexual functional outcomes of vaginal dilation therapy for MRKH syndrome: a prospective study

Objectives: To report the sexual functional outcomes of vaginal dilation therapy in Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome patients. Methods: From March 2020 to February 2023, 97 MRKH syndrome patients performed vaginal dilation therapy with guidance from Peking Union Medical College Hospital, and 45 of them engaged in penetrative intercourse and were included in this prospective cohort study. The Chinese version of female sexual function index (FSFI) was used to assess sexual function. Functional success was defined as FSFI>23.45. Forty age-matched healthy women were selected as controls. Kaplan-Meier survival analysis was used to calculate the median time to success. Pearson correlation analysis was used to explore the relationship between neovagina length and sexual function. Complications were collected using follow-up questionnaires. Results: The functional success rate of vaginal dilation therapy was 89% (40/45) with a median time to success of 4.3 months (95%CI: 3.0-6.1 months). Compared to controls, MRKH syndrome patients had significantly lower scores in the orgasm domain (4.72±1.01 vs 4.09±1.20; P=0.013) and pain domain (5.03±0.96 vs 4.26±0.83; P<0.001). However, there were no significant differences in the FSFI total score (26.77±2.70 vs 26.70±2.33; P=0.912), arousal domain (4.43±0.77 vs 4.56±0.63; P=0.422) and satisfaction domain (4.88±0.98 vs 4.65±0.86; P=0.269) between MRKH syndrome patients and controls. MRKH syndrome patients had significantly higher scores in the desire domain (3.33±0.85 vs 3.95±0.73; P<0.001) and lubrication domain (4.37±0.56 vs 5.20±0.67; P<0.001). The prevalence of sexual dysfunction in MRKH patients was non-inferior to controls: low desire [3% (1/40) vs 23% (9/40); P=0.007], arousal disorder [3% (1/40) vs 3% (1/40); P>0.999], lubrication disorder [5% (2/40) vs 25% (10/40); P=0.012], orgasm disorder [40% (16/40) vs 20% (8/40); P=0.051], sexual pain [30% (12/40) vs 15% (6/40); P=0.108]. Conclusions: MRKH syndrome patients undergoing non-invasive vaginal dilation therapy could achieve satisfactory sexual life. Given its high functional success rate and slight complication, vaginal dilation therapy should be recommended as the first-line option, reducing the need for unnecessary surgeries.

Regression course of ostium granulomas under topical intranasal steroids coverage after endoscopic dacryocystorhinostomy

This study aimed to elucidate the regression process of ostium granulomas under the usage of intranasal steroid after primary endoscopic dacryocystorhinostomy (DCR). The authors retrospectively reviewed 57 patients (a total of 72 ostia) who had ostium granulomas after primary endoscopic DCR between 2011 and 2015. Topical intranasal steroid spray was applied in all the patients since postoperative day 1. Adjunctive intralesional triamcinolone acetonide injections were administered for extensive and large-sized granulomas that caused impending ostium blockage. Sequential regression of the ostium granulomas and success rates of DCR were assessed using endoscopic photos. The granulomas completely disappeared in 69 (95.8%) ostia, and the average time interval from the surgery to the disappearance was 6.9 ± 2.8 months. Anatomical and functional surgical success rates were 90.3% and 84.7%, respectively. Intralesional steroid injections for ostium granulomas did not alter the outcomes compared to topical intranasal steroid usage significantly (p = 0.445). In conclusion, we observed that, by continuing the usage of intranasal steroids, ostium granulomas disappear gradually at postoperative 6 months. The intranasal surgical manipulation of granulomas, which results in more mucosal cicatricial change and impedes patient satisfaction, can be successfully avoided.

Comparison of femoral tunnel position and knee function in anterior cruciate ligament reconstruction: a retrospective cohort study using measuring-fluoroscopy method versus bony marker method

BackgroundPrevious studies have shown that surgical technique errors especially the wrong bone tunnel position are the primary reason for the failure of anterior cruciate ligament (ACL) reconstruction. In this study, we aimed to compare the femoral tunnel position and impact on knee function during the ACL reconstruction using measuring combined with fluoroscopy method and bony marker method for femoral tunnel localization.MethodsA retrospective cohort study of patients undergoing ACL reconstruction using the bony marker method or measuring combined with fluoroscopy for femoral tunnel localization was conducted between January 2015 and January 2020. A second arthroscopic exploration was performed more than 1 year after surgery. Data regarding patient demographics, the femoral tunnel position, results of the Lysholm score, the International Knee Documentation Committee (IKDC) score, KT-1000 side-to-side difference, pivot shift grade, and Lachman grade of the knee were collected.ResultsA total of 119 patients were included in the final cohort. Of these, 42 cases were in the traditional method group, and 77 cases were in the measuring method group. The good tunnel position rate was 26.2% in the traditional method group and 81.8% in the measuring method group (p < 0.001). At the final follow-up, the Lysholm and IKDC scores were significantly greater in the measuring method group than the traditional method group (IKDC: 84.9 ± 8.4 vs. 79.6 ± 6.4, p = 0.0005; Lysholm: 88.8 ± 6.4 vs. 81.6 ± 6.4, p < 0.001). Lachman and pivot shift grades were significantly greater in the measuring method group (p = 0.01, p = 0008). The results of KT-1000 side-to-side differences were significantly better in the measuring method group compared with those in the traditional method group (p < 0.001).ConclusionsThe combination of the measuring method and intraoperative fluoroscopy resulted in a concentrated tunnel position on the femoral side, a high rate of functional success, improved knee stability, and a low risk of tunnel deviation. This approach is particularly suitable for surgeons new to ACL reconstructive surgery.

Retrospective study of the deep circumflex iliac artery flap and the vascularized fibula free flap for maxillary defect repair

ObjectivesThe deep circumflex iliac artery flap (DCIA) and vascularized fibular free flap (FFF) are mainstay flaps for maxillary defect reconstruction. This study compared the functional outcomes and success rates of these flaps to provide midface reconstruction strategies. Materials and MethodsMaxillary defects reconstructed with DCIA or FFF at the Department of Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology between May 2016 and May 2023 were retrospectively analyzed. The length, width, and height of the grafted bone segments; intermaxillary distance; buttress reconstruction rate (BRR); dental arch reconstruction rate (DAR); success rate; and dental implantation rate were compared. ResultsThe DCIA and FFF groups had 33 and 27 patients, respectively. Success rate in the DCIA group was 93.94 % and 100 % in the FFF group. The DCIA length was less than that of FFF; however, the width and height were significantly larger. 87.10 % of cases in the DCIA group were classified as Brown class b and c, 51.85 % of cases in the FFF group were classified as Brown class d. The average BRR in the DCIA group was 69.89 % ± 16.05 %, which was significantly higher than that in the FFF group. A total of 38.7 % and 11.1 % patients in the DCIA and FFF groups, respectively, had completed implantation. ConclusionDCIA has a greater width and height, and is more suitable for repairing Brown class b and c defects, providing sufficient bone for implantation, while the FFF is longer and more suitable for Brown class d defect reconstruction.

Prognosis of concurrent endoscopic dacryocystorhinostomy and nasal septoplasty for chronic dacryocystitis with moderate nasal septum deviation.

The prognosis of combined septoplasty and endoscopic dacryocystorhinostomy (En-DCR) for moderate nasal septum deviation (NSD) has not yet been fully investigated. To evaluate whether septoplasty improves the prognosis of En-DCR for moderate NSD. A retrospective cohort study in a real-world clinical setting. The postoperative FICI DCR ostium grading scores and functional and anatomical information at 1, 2, 3, and 6 months were determined for consecutive patients with chronic dacryocystitis (CD) and moderate NSD who underwent En-DCR. Univariate and generalized estimating equation multivariate analyses were used to compare the outcomes of the septoplasty and non-septoplasty groups. En-DCR and septoplasty were concurrently performed for 32 (20.1%, 32/158) cases. The total FICI DCR ostial scores for the septoplasty and non-septoplasty groups were highest at the first (4.97 ± 0.177 vs. 4.97 ± 0.176, P > 0.05) and lowest at the sixth (4.41 ± 1.341 vs. 4.50 ± 1.355, P > 0.05) postoperative months. At the end of follow-up, the two groups showed comparable proportions of patients requiring definitive intervention for the ostium (6.3% vs. 7.1%, P > 0.05), comparabe functional success rates (87.5% vs. 90.5%, P > 0.05) and anatomical success rates (93.8% vs. 92.9%, P > 0.05). Only the non-septoplasty group experienced nasal mucosal adhesions (3.2%, 4/126). In patients with CD and moderate NSD, nasal septoplasty did not impact En-DCR prognosis, but reduced the complications. Skilled surgeons should reconsider septoplasty in the absence of otolaryngological indications.

Long-Term Outcomes of Keratoprosthesis With Biological Haptic: A Review of 25 Years of Single-Center Surgeries.

To study the outcome of eyes that underwent surgery for keratoprosthesis with a biological haptic, osteo-odonto-keratoprosthesis (OOKP) or tibia keratoprosthesis, by a single surgeon over a time span of more than 25 years. One hundred thirty eyes that had received a keratoprosthesis with a biological haptic between 1994 and 2022 by a single surgeon were included in this retrospective analysis. Main outcome parameters were postoperative best corrected visual acuity, postoperative refractive error, postoperative complications, anatomical and functional survival of the prosthesis as well as comparison of subgroups of the 2 different types (OOKP n = 78; tibia keratoprosthesis n = 52) of keratoprostheses, and subgroup analysis of different indications for surgery. Patients were examined every 6 months. The longest follow-up was 25.8 years. Reasons for implantation were graft-vs-host disease (6.9%), vascularized corneas and dry eye (22.9%), physical or chemical burns (29.8%), Stevens-Johnson syndrome (9.9%), and ocular cicatricial pemphigoid (30.5%). The functional success rate with postoperative visual acuity of better than 0.7 log MAR was achieved by 56.9%. The OOKP subgroup showed a better mean visual outcome. 14 keratoprostheses (10.7%) had to be explanted over the whole time span. In the time leading to explantation, refraction showed a statistically significant myopic shift when compared with the non-explanted prosthesis. Anatomical survival rates were better for the OOKP in the first 12 years after implantation. The study shows that keratoprosthesis with a biological haptic has favorable long-term outcomes. The retention rate stayed very high with excellent functional outcomes.

A New Method in Transcanal Medial Grafting Type-I Cartilage Tympanoplasty.

To determine the surgical results of a modified technique for the tympanic membrane (TM) perforation repair and to compare this new technique with the traditional methods. An interventional study. Place and Duration of the Study: Department of Otolaryngology, Medicana International Hospital, Samsun, Turkiye, from June 2019 till June 2021. The study was conducted with 24 patients who underwent cartilage tympanoplasty. Pure-tone audiometry (PTA), preoperative and postoperative air and bone conduction hearing levels were determined. The mean values of air and bone conduction and air-bone gap (ABG) were recorded. Postoperatively, 23 grafts were intact, and one was perforated, perforation secondary to otomycosis in the first month postoperatively. Eight patients had previous unsuccessful tympanoplasty history. These patients' tympanic grafts were intact with this technique. Surgical success rate was 96.0%. Postoperative hearing gain was 12,8 dB. Functional success rate was 88.0%. Mean surgery time was 30 minutes. Patients easily continued their lives in one-week time after the surgery. The new modified cartilage tympanoplasty method had high surgical success, and good audiometric results were obtained. Type-I cartilage, Tympanoplasty, Transcanal medial grafting, Tympanomeatal flap elevation.

Comparison of the Impacts of Different Middle Ear Mucosal Conditions on Type I Tympanoplasty Outcomes.

This study aimed to explore the impacts of different middle-ear mucosal conditions on the outcomes of type I tympanoplasty. A retrospective analysis of 164 patients with chronic otitis media was carried out. The patients were divided into 4 groups according to their mucosal condition. Preoperative hearing levels and air-bone gap (ABG) before and after surgery were compared via the Kruskal‒Wallis H test. The chi-squared test and Fisher's exact test were used to assess the postoperative complications and impact factors of functional success. Preoperatively, neither the air conduction nor bone conduction values differed significantly among groups with different mucosal conditions. All of the ABG closed dramatically after type I tympanoplasty (P < .05) regardless of the mucosal conditions. The functional success rates were lower when the intratympanic mucosa was moderately or severely edematous compared with mildly edematous or normal (P < .05). The disease course, perforation site, and perforation size, as well as the status of the opposite ear, were not related to the auditory functional outcome. The differences in postoperative reotorrhea and reperforation among the 4 groups were not statistically significant. Preoperative hearing levels were not affected by middle-ear mucosal conditions. The functional success rate was influenced by mucosal conditions, but hearing levels were significantly enhanced after surgical intervention regardless of the mucosal status. Postoperative complications were not related to the mucosal conditions. Thus, type I tympanoplasty is adoptable for mucosal abnormalities when pharmacotherapy cannot result in a healthy tympanum.

Long-term outcomes of modified transcanalicular diode laser dacryocystorhinostomy.

The purpose of this study is to assess the long-term outcomes of modified transcanalicular diode laser dacryocystorhinostomy in a large cohort of patients affected by primary acquired nasolacrimal duct obstruction. This study, conducted from January 17 to June 2022, encompassed 141 patients (159 procedures) who underwent modified transcanalicular diode laser dacryocystorhinostomy (MT-DCR). The procedure employed an 810-nm diode laser. Patients were monitored for at least a year after the intervention. Anatomical success was determined by ostium patency upon irrigation, while functional success referred to epiphora resolution. Parameters studied included patient demographics, procedure duration, complications, and both anatomical and functional success. Statistical analysis was performed using the Statistical Package for the Social Sciences software, with results considered significant at a 95% confidence interval (p≤0.05). A total of 159 lacrimal drainage systems (141 patients: 112 women and 29 men) were included in this study. Among them, 18 underwent bilateral procedures. The average patient age was 58 years (range: 34-91 years), and the average surgical duration was 24 minutes (range: 18-35 minutes). One year after the surgery, MT-DCR exhibited anatomical and functional success rates of 84.9% (135/159) and 83% (132/159), respectively. MT-DCR achieved an anatomical success rate of 84.9%, reflecting an excellent outcome. However, further extensive studies with larger sample sizes and longer follow-up periods are necessary to substantiate these findings.

Outcomes of external and endonasal dacryocystorhinostomy according to a modified Lacrimal Symptom Questionnaire (Lac-Q).

Nasolacrimal duct obstruction is usually treated using endoscopic or external dacryocystorhinostomy (DCR). The anatomic outcomes of both the endoscopic and external approaches are considered excellent. However, anatomic success does not translate into patient satisfaction. The current study assessed pre- and postoperative lacrimal problems using the symptom-based Lacrimal Symptom Questionnaire (Lac-Q) and investigated patient satisfaction depending on the choice of surgical technique. A total of 112 eligible patients with lacrimal problems treated using external or endonasal DCR at the ophthalmology and ear, nose, and throat clinics at Skane University Hospital, Scania, Sweden, over a four-year period, were enrolled in this retrospective study. Patients were considered eligible if they experienced preoperative epiphora and had lacrimal duct stenosis. They were offered treatment using either external or endonasal DCR and were allowed to freely choose the technique. Exclusion criteria consisted of previous ipsilateral DCR, congenital NLDO, age < 18 years, presence of cancer, previous orbital trauma, or noncompliance with postoperative follow-up. After surgery, the patients were sent the Lac-Q to evaluate their lacrimal symptoms pre- and postoperatively. Complementary questions were added pertaining to the operative scar and the patients' overall satisfaction with the operation. In total, 67 (60%) patients with ages ranging from 18 to 88 years completed the questionnaire, 33 (49%) of whom underwent external DCR and 34 (51%) endonasal DCR. Of the 67 respondents, 51 (76%) were women and 16 (24%) were men. Patients scored preoperative lacrimal problems highly on the Lac-Q, reporting both symptomatic and social problems due to epiphora. Following surgery, the group that underwent external DCR remained home from work for 2 - 14 days (median, 3.5 days). However, 17 (52%) were retired. After the endonasal DCR, the patients remained home for 0 - 7 days (median, 2 days). Most patients were satisfied after DCR surgery, with both techniques significantly improving total, lacrimal symptom, and social impact scores (all P < 0.001). No differences in postoperative satisfaction were observed between the external DCR and endonasal DCR groups (P > 0.05). A small number of patients expressed scar-related concerns after external DCR. The patients perceived lacrimal problems as a significant symptomatic and social burden. Postoperative satisfaction and symptom relief were good regardless of the surgical approach. Further prospective studies assessing patient satisfaction and its correlation with anatomical and functional success rates after external and endonasal DCR could provide robust, practical, real-world implications.

Cardiac computed tomography-based assessment of mitral annular calcification in patients undergoing mitral transcatheter edge-to-edge repair

BackgroundThe role of assessment of mitral annular calcification (MAC) using cardiac computed tomography (CCT) in mitral transcatheter edge-to-edge repair (TEER) remains unclear. The aim of this study was to investigate the association of MAC assessed by CCT with procedural and clinical outcomes in patients undergoing TEER. MethodsWe retrospectively analyzed 275 patients who underwent pre-procedural CCT prior TEER. Mitral calcium volume (MCV) and MAC score were measured by CCT. Functional procedural success was defined as residual mitral regurgitation of ≤2+ with mean transmitral gradient of <5 ​mmHg at discharge. All-cause mortality within two years after TEER was collected. ResultsMAC was present in 115 of 275 patients (41.8 %). The median MCV was 198 ​mm3 (interquartile range [IQR]: 84 to 863 ​mm3), and the median MAC score was 3 (IQR: 2 to 4). Higher MCV and MAC score were inversely related to the rate of functional procedural success, independently of anatomical features of mitral valve. Patients with moderate/severe MAC, defined as MAC score of ≥4, had a lower rate of functional procedural success than those without MAC (56.1 ​% vs. 81.3 ​%; p ​= ​0.002). Moreover, higher MCV and MAC score were associated with a higher risk of all-cause mortality within two years, irrespective of baseline characteristics and functional procedural success. ConclusionsThe presence and burden of MAC assessed by CCT were associated with procedural and clinical outcomes in patients undergoing TEER. The CCT-based assessment of MAC may improve patient selection for TEER.

Comparison of the surgical outcomes of endoscopic dacryocystorhinostomy in chronic dacryocystitis with or without previous bicanalicular silicone tube intubation

AimsTo compare the outcomes of endoscopic dacryocystorhinostomy (En-DCR) in chronic dacryocystitis (CD) with or without previous bicanalicular silicone tube intubation (BSTI), and investigate whether previous BSTI influenced postoperative outcomes. MethodsWe conducted a retrospective review of medical records of CD patients (group A) who had previously undergone BSTI for nasolacrimal duct stenosis and an age- and sex-matched control group of CD patients (group B) without previous intubation receiving En-DCR from November 2017 to January 2022. Sixty-one patients (61 eyes) were included in group A and age- and sex-matched 122 patients (122 eyes) in group B. Dacryocystic parameters were measured by computed tomography-dacryocystography and surgical findings were recorded during surgeries. The surgical success rates of the two groups were compared at 12 months post-operation. ResultsThe mean horizontal, sagittal, and vertical lengths were 6.06 ± 1.24, 6.03 ± 1.44, and 8.05 ± 2.00 mm, respectively, in group A and 6.33 ± 1.25, 6.26 ± 1.19, and 10.40 ± 2.45 mm, respectively, in group B. There were no differences in the horizontal or sagittal parameters between the two groups. The vertical parameter in group A was significantly lower than that in group B. Scar formation in the sac was observed in 54 patients in group A but was absent in group B. At 12 months postoperatively, the anatomical and functional success rates were 88.52 % and 85.25 %, respectively, in group A and 92.62 % and 89.34 %, respectively, in group B, with no difference between the two groups. ConclusionPrevious BSTI reduced dacryocyst vertical parameter and caused dacryocyst scar formation but did not affect postoperative En-DCR efficacy.

Inside-out raising mucosal-tympanomeatal flap approach for the repair of large marginal perforations

ObjectiveThis study evaluated the graft success rate and hearing outcomes of the inside-out raising mucosal-tympanomeatal flap technique for the repair of large marginal perforations.Study designProspective case series.Materials and methodsThe study enrolled patients with large marginal perforations who underwent endoscopic cartilage myringoplasty with the inside-out raising mucosal-tympanomeatal flap technique. The graft success rate, hearing outcomes, and complications were evaluated at 12 months postoperatively.ResultsIn total, 48 patients with large marginal perforations were included. 81% of the population had large perforation, 14.6 had subtotal and total perforation was seen in 4.2%. The mean operation time was 38.6 ± 7.1 min. At 12 months postoperatively, the graft success rate was 89.6% (43/48). The mean air-bone gap was 25.6 ± 5.2 dB preoperatively and 16.5 ± 4.1 dB at 12 months postoperatively, with significant differences between these values (p = 0.001). The functional success rate was 85.4% (41/48). None of the patients experienced worsened sensorineural hearing loss or graft-related complications, such as graft lateralization, significant blunting, and graft medialization, during follow-up.ConclusionsEndoscopic cartilage-perichondrium myringoplasty for the repair of large marginal perforations using the inside-out raising mucosal-tympanomeatal flap technique was associated with satisfactory graft outcomes and minimal complications.

NYHA class IV in patients with degenerative mitral regurgitation undergoing transcatheter edge-to-edge repair: Results of the worldwide, multicenter PRIME-MR registry

Abstract Background Patients with degenerative mitral regurgitation (DMR) presenting with resting dyspnoea (New York Heart Association [NYHA] class IV), particularly in cases of acute onset or rapid deterioration, constitute a high-risk cohort with significant implications for preprocedural planning. This study aims to assess whether preprocedural NYHA class IV is associated with adverse events and outcomes in DMR patients undergoing Transcatheter mitral edge-to-edge repair (TEER), by analyzing data from the PRIME-MR registry. Methods PRIME-MR, a retrospective, investigator-initiated, multicenter registry, comprises patients who underwent TEER for relevant DMR in 24 high-volumes centres between 2008 and 2022. The primary objective was to evaluate the outcomes of patients with resting dyspnoea (defined as NYHA class IV at baseline) and compare these to patients presenting with NYHA class II or III. Results In this analysis, 1,941 consecutive patients (median age: 81 years [IQR 76; 85]; 46.8% female; mean STS Mortality Score [mitral repair]: 5.0% ± 3.9) with available follow-up data were included (median follow-up time 2.56 years [95%-confidence interval 2.39; 2.47]). Of these patients, 323 (16.6%) presented with NYHA class IV at baseline. There were no differences at baseline in terms of median left ventricular ejection fraction (NYHA IV: 58% [IQR 50; 64] vs. NYHA II/III: 60% [IQR 50; 65]; p=0.30) or right ventricular function, measured by TAPSE (NYHA IV: 19mm [IQR 15; 22] vs. NYHA II/III: 19mm [IQR 16; 23]; p=0.088). DMR severity was comparable between the groups (effective regurgitation orifice area [EROA]: NYHA IV 0.5cm² [IQR 0.4; 0.7] vs. NYHA II/III: 0.4cm² [IQR 0.3; 0.6]; p=0.052). The main pathology differed between both groups, with higher proportions of flails in patients with NYHA IV (57.3% [n=142] vs. NYHA II/III: 48.4% [n=674]; p=0.013). NYHA class IV patients had higher median levels of baseline NT-proBNP (NYHA IV: 3182ng/L [1411; 7966] vs. NYHA II/III: 1875ng/L [IQR 803; 3968]; p&amp;lt;0.001). Functional success rates according to M-VARC criteria (residual mitral regurgitation [rMR] ≤2+, EROA ≤0.15cm², transmitral pressure gradient ≤5 mmHg) were comparable (NYHA IV: 71.4% [n=200] vs. NYHA II/III: 73.5% [n=1060]; p=0.52). Postprocedural efficacy was high in both groups (rMR ≤2+ at discharge in NYHA IV: 87.4% [n=243] vs. NYHA II/III: 90.4% [n=1,344]; p=0.59; Figure 1). However, Kaplan-Meier analysis for all-cause mortality or rehospitalization after two years revealed worse outcomes of patients with NYHA IV (log-rank p=0.002; Figure 2). Conclusion This analysis of the PRIME-MR registry revealed that, despite similar baseline characteristics and high procedural efficacy in both groups, the presence of NYHA class IV at baseline was associated with inferior clinical outcomes in DMR patients undergoing TEER. As such, it represents an important indicator of increased risk of mortality and rehospitalization and may require closer patient follow-up.MR at baseline and dischargeKaplan Meier analysis
