Epigastric Ventral Hernia Repair Through Vaginal Natural Orifice Transluminal Endoscopic Surgery.

Ventral hernia repair is a commonly performed operation and can be executed by open or laparoscopic approach. The search for even less invasive techniques continues. Natural orifice transluminal endoscopic surgery (NOTES) is a known method of minimally invasive surgery. We performed an epigastric ventral hernia repair through vaginal NOTES during a concurrent hysterectomy and bilateral salpingectomy. We used the access to do a synchronous hernia repair with mesh augmentation. The technique of repair was identical to the laparoscopic intraperitoneal onlay mesh repair (Lap. IPOM). We reported a sufficient hernia repair without intra-operative complications. Also, post-operatively, no problems were encountered. Follow-up after 4 weeks showed a good and strong hernia repair. The complaints of the patient were relieved. CT scan 10 months after operation showed no recurrence nor signs of mesh infection. Ventral hernia repair through vaginal NOTES can be considered a possible new and minimal invasive (scarless) technique for ventral hernia repair but further investigations on a larger scale are needed to confirm feasibility & safety.

OTHR-17 MANAGEMENT AND OUTCOMES OF SELLAR, SUPRASELLAR, AND PARASELLAR MASSES IN LOW- AND MIDDLE-INCOME COUNTRIES: A SCOPING REVIEW AND PROPORTIONAL META-ANALYSIS OF 6584 MASSES

Abstract OBJECTIVE To aggregate data on treatment modalities, management approaches, and clinical outcomes of sellar, suprasellar, and parasellar masses in LMICs. METHODS We conducted a scoping review as per the Arksey and O’Malley framework. MEDLINE, Embase, Global Index Medicus, and African Journals Online were searched and included articles between 2000 and 2021 screened against predefined eligibility criteria. Pooled statistics were calculated using measures of central tendency and spread. A proportional meta-analysis was conducted to pool the mortality rates. RESULTS Of the 3526 articles generated by the search strategy, 173 articles were included. The mean age was 35.5 ± 15 years, and most were females (56.47%). Sellar masses predominated (85%; 95% CI = 93.16–118.58), and the most commonly used neuroimaging modality to diagnose these masses was an MRI (65.31%). Surgical resection was mostly utilised with endoscopic surgery (78%; 95% CI = 17.29–154.96) predominating over microsurgery (22%; 95% CI = 11.51–47.73). The transsphenoidal approach was mostly used for both endoscopic surgery and microsurgery (92.13% vs 93.21%), and the extent of resection was gross total resection in most cases (n = 3611). Non-surgical management included hormonal therapies (n = 2080), chemotherapy (n = 96 patients), and radiosurgery (n = 357). New onset diabetes insipidus (34.27%), followed by postoperative infection (27.95%), were the most commonly reported postoperative complications. The pooled overall mortality rate was 8.1% (95% CI: 0.031–0.146). CONCLUSION Although MRIs are considered to be the gold standard means of diagnosis for these masses, their use in LMICs is less reported. Despite new minimally invasive treatment options, endoscopic surgery is commonly used in LMICs. These translates to the fact that more effort is required in the effective care of patients with these masses in LMICs.

A clinical comparative study of an outpatient treatment group and an endoscopic sinus surgery group for maxillary sinus fungus ball.

This study aimed to clarify the differences in the pathophysiology of maxillary sinus fungus balls (FB) among different case groups and to identify which patients with maxillary sinus FB would be suitable for outpatient procedures. Thirty-four patients diagnosed with maxillary sinus FB between January 2017 and December 2021 were divided into two groups (O and S). We retrospectively compared the clinical and imaging characteristics, and the treatment outcomes between the groups. Group O comprised 12 patients (13 sides) treated in an outpatient clinic and Group S comprised 15 patients (16 sides) treated with endoscopic sinus surgery (ESS). Compared to Group S, Group O had more patients with an enlarged maxillary sinus membranous portion, and shadows indicative of fungal masses (P < 0.01 and P < 0.05, respectively). In particular, the anteroposterior ratio of the open maxillary sinus membranous area was 0.68 ± 0.16 in Group O and 0.5 ± 0.12 in Group S. After surgery, Group O exhibited greater anteroposterior expansion of the maxillary sinus membranous portion compared to Group S (P < 0.01). Additionally, Group O had more patients with shadows in sinuses other than the maxillary sinus (P < 0.01) and medial displacement of the uncinate process (P < 0.01) than Group S. In addition, Group O required fewer procedures and hospital visits than Group S (P < 0.001 and P < 0.01, respectively). Determining the indications for outpatient procedures while considering the pathophysiology of maxillary sinus FB can significantly benefit patients and medical professionals in terms of safety and medical costs.

Silent Sinus Syndrome: A Paediatric Condition Diagnosed in the Orthodontic Department

Silent sinus syndrome (SSS) is defined as unilateral maxillary sinus hypoplasia and orbital floor resorption. This case report highlights a rare paediatric diagnosis of SSS during an orthodontic clinic. The diagnostic orthopantogram (OPG) and cone-beam computed tomography showed complete opacification of the left maxillary sinus. Following referral to the ear, nose and throat (ENT) department, a CT sinus confirmed SSS. Owing to the risk of facial asymmetry in a growing adolescent patient without surgical intervention, functional endoscopic sinus surgery will be used to manage this. This case highlights the importance of a thorough investigation of incidental findings. CPD/Clinical Relevance: The clinical relevance of early diagnosis of silent sinus syndrome and its implications on facial symmetry is discussed.

Screening for Psychiatric Disorders in Chronic Rhinosinusitis Patients Waiting for Surgery: A Prospective Cross-Sectional Study.

To assess the prevalence of depression, anxiety, insomnia and somatic symptom disorder (SSD) in chronic rhinosinusitis (CRS) patients who were waiting for surgery and to predict these psychiatric disorders using the 22-item Sinonasal Outcome Test (SNOT-22). A prospective cross-sectional study. The rhinology ward at our institution, a tertiary hospital. Adult patients (> 18 years) diagnosed with CRS who were admitted to the rhinology ward for endoscopic sinus surgery and were able to understand and complete the study questionnaires. Patient Health Questionnaire-9 (PHQ-9), Generalised Anxiety Disorder-7 (GAD-7), Insomnia Severity Index (ISI), Patient Health Questionnaire-15 (PHQ-15) and SNOT-22. Of the 159 participants recruited, 58 were at risk of depression (defined by PHQ-9 > 4, while 25 with PHQ-9 > 9), 49 were at risk of anxiety (defined by GAD-7 > 4, while 25 with GAD-7 > 9), 81 were at risk of insomnia (defined by ISI > 7, while 51 with ISI > 14) and 69 were at risk of SSD (defined by PHQ-15 > 4, while 24 with PHQ-15 > 9). The SNOT-22 score was closely correlated with the scores of psychometric tests and was an independent predictor of these psychiatric disorders. Patients with a high SNOT-22 score (> 30) are likely to be affected by comorbid psychiatric disorders and should be further evaluated by otolaryngologists. Depression, anxiety, insomnia and SSD are prevalent in CRS patients. Otolaryngologists should have a low threshold to ask the patient about psychiatric symptoms, especially for patients with an SNOT-22 score > 30.

Association between postoperative pain and analgesic use in minimally invasive cardiac surgery.

This study aimed to investigate the effects of surgical methods on pain duration and oral analgesic administration in patients who underwent cardiac surgery using various minimally invasive methods. We included 90 patients who underwent an anterior incision with costal cartilage transection, lateral incision without costal cartilage transection, or total endoscopic cardiac surgery using a lateral incision and no retractor. Oral analgesics were postoperatively administered upon patient request. All the patients were instructed to rate their pain during the daytime 3 and 7 days postoperatively. Between-group differences included surgical method, wound size, operation/cardiopulmonary bypass time/cardiac arrest time, and intraoperative fentanyl dose. No differences were found in sex, age, diabetes status, paravertebral block use, or blood loss. The number of postoperative days, postoperative analgesic use, and pain 3 days postoperatively demonstrated no difference. Pain ratings were most severe for the costal cartilage resection group and least severe for the total endoscopic cardiac surgery group 7 days postoperatively. Similarly, patients who underwent costal cartilage research exhibited the highest rate of analgesic use for 30 days postoperatively, whereas patients who underwent total endoscopic cardiac surgery demonstrated the lowest. We revealed significant between-group differences in pain prevalence and postoperative oral analgesic administration in patients who underwent cardiac surgery relative to the minimally invasive surgical method used.

Effect of hot saline irrigation on the operative field during endoscopic sinus surgery: a randomized controlled trial.

Control of bleeding is very important during endoscopic sinus surgery. Saline heated up to 50°C causes dilatation of vessels and edema without nasal mucosa necrosis. It also promotes the clotting cascade so helps in having a bloodless procedure. This randomized controlled trial was conducted on 60 patients divided into two groups (30 each). Group A was the interventional group in which patients were irrigated with saline of 50°C during surgery. Group B was the control group where room-temperature saline was used. The operative field was assessed using the Boezaart score, duration of surgery, and bleeding in ml. The Boezaart score in group A came out to be 2.23 ± 0.72 whereas it was 3.43 ± 0.72 in group B. Most of the patients who were in the interventional group had their surgery completed within 60min with comparatively less bleeding (mean bleeding = 221.83ml). Patients of the control group had increased duration of surgery mostly and bleeding (mean = 265.67ml). Our study showed a strong correlation amongst the Boezaart score, duration of surgery, and bleeding in ml with a p value of < 0.001 where all three variables significantly improved in the interventional group due to a good operative field provided by warm saline heated up to 50°C. Normal saline heated up to 50°C is a cost-effective way to achieve a bloodless operative field during endoscopic sinus surgery. Reduced bleeding also decreases the duration of surgery.

Learning Curve of Endoscopic Lumbar Discectomy - A Systematic Review and Meta-Analysis of Individual Participant and Aggregated Data.

A systematic review and meta-analysis of individual participant and aggregated data. To define the learning curves of endoscopic discectomies using unified statistical methodologies. Searches returned 913 records, with 118 full-text articles screened. Studies of endoscopic lumbar spine surgery reporting outcomes by case order were included. Mixed-effects nonlinear, logistic, and beta meta-regressions prdwere conducted to define the learning curves. 13 studies involving 864 patients among 15 surgeons were included in total. For transforaminal endoscopic discectomy, the estimated operating time for the first case was 95min [CI: 87-104], and the estimated plateau was 66 minutes [CI: 51-81]. An estimated 21 cases [CI: 18-25] were required to overcome 80% of this deficit, but near-plateau performance was expected only after 59 cases [CI: 51-70]. The estimated risk of surgical complications on the first case was 25% [CI: 11%-46%], with an 80% reduction in relative risk requiring an estimated 41 cases. The expected postoperative VAS leg pain score after the first case was 2.7 [CI: 1.8-3.8], with an 80% improvement requiring an estimated 96 cases. Similar numbers were required to overcome the learning curves in interlaminar and biportal endoscopic discectomies. Approximately 60 cases are required to achieve proficiency in endoscopic lumbar spine surgery, although the greatest part of the learning curve can be overcome with 20 cases. This should be considered when designing implementation programmes for surgeons and service providers that wish to incorporate endoscopic spinal surgery into their practice.

Semi-Quantitative Assessment of Surgical Navigation Accuracy During Endoscopic Sinus Surgery in a Real-World Environment.

Although surgical navigation is commonly used in rhinologic surgery, data on real world performance are sparse because of difficulties in collecting measurements for target registration error (TRE). Despite publications showing submillimeter TRE, surgeons do report TRE of >3 mm. We describe a novel method for assessing TRE during surgery and report findings with this technique. The TruDi navigation system (Acclarent, Irving, CA) was registered using a contour-based protocol. The surgeon estimated target registration error (e-TRE) at up to 8 points (anatomic regions of interest [ROI]) during endoscopic sinus surgery (ESS). System logs were used to simulate the localization for quantitative assessment of TRE (q-TRE). We performed 98 localizations in 20 patients. The ROI in the sinuses were ethmoid (33 sites), maxillary (28 sites), frontal (17 sites), and sphenoid (22 sites). For localizations, mean qTRE and eTRE were 0.93 and 0.84 mm (P = .56). Notably, 80% of qTRE and 81% of eTRE were 1 mm or less. Mean qTRE and eTRE were less for attending-performed registrations at the maxillary, frontal and sphenoid. Surgical navigation accuracy, as measured by qTRE and eTRE, approaches 1 mm or better at all sinus sites in a real-world setting for 80% of localizations. The qTRE method provides a unique approach for assessing TRE. Surgeons underestimate TRE (overstate navigation accuracy), but this difference does not seem to be statistically significant. Registration performed by trainees yields higher TRE than registration performed by attendings. These data may be used to guide navigation optimization.

Prospective Study on Coblation Vs. Cautery in Endoscopic Trans Sphenoidal Surgery for Pituitary Macroadenoma: Impact on Nasal Function.

Endoscopic endonasal Trans-sphenoidal surgery for sellar-suprasellar tumors is considered the preferred route. The ideal instruments in skull base surgery should be able to manipulate adequately through the narrow corridors with effective tissue removal and bleeding control and reduce collateral damage to nearby vital structures. The present study sought to compare the nasal morbidity following transnasal sphenoidal surgery for pituitary macroadenoma using Coblation and Electrocautery. 160 undergoing Endoscopic TSS for non-functioning PAs were enrolled. The patients were randomly allocated into Coblation (n = 80) and electrocautery (n = 80) groups. All operations were performed by the same group of surgeons skilled in their surgical techniques. There were 59 and 53 patients with Knosp grade II tumors in the cautery and coblation group, respectively, while 21 and 27 patients had Knosp grade III tumors. The average duration of surgery using cautery was 96+/-4.5min, while with coblation, the average time was 83+/-3.5min, and the difference was statistically significant. Nasal crusting and granulation severity were observed more in the electrocautery group. The coblation group patients had clear surgical fields with few ooze points; the difference between the two groups was significant. Nasal synechiae and decreased nasal patency were common in the electrocautery group. There were no statistical differences in nasal bleeding, nasal deformity, or sense of smell parameters. Advanced medical tools like coblation are safe and effective for the dissection and ablation of the mucosa. They result in better intra-operative visualization and lesser postoperative nasal morbidity, which will help patients achieve a better quality of life.

Multi-center study on sellar reconstruction after endoscopic transsphenoidal pituitary surgery.

Surgical techniques for sellar reconstruction include no reconstruction, use of synthetic materials, autologous grafts, and/or vascularized flaps. The aim of this study was to conduct a multi-center study comparing the efficacy and postoperative morbidity associated with different sellar reconstruction techniques. A retrospective chart review of patients who underwent endoscopic transsphenoidal surgery for pituitary tumors from five participating sites between January 2021 and March 2023 was performed. The variables included demographics, tumor characteristics, reconstruction technique, postoperative cerebrospinal fluid leak (CSF) leak, and 22-item Sino-Nasal Outcome Test (SNOT-22) scores. Comparisons of postoperative complications, SNOT-22 scores, and duration of surgery by type of onlay reconstruction were evaluated using Fisher's exact test, analysis of variance, and Kruskal‒Wallis test. Five hundred and one patients were identified. The median tumor size was 2.1cm, and 64% were non-functioning. Intraoperative CSF leak was identified in 38% of patients. A total of 89% of patients underwent onlay reconstruction: 49% were reconstructed with mucosal grafts, 35% with nasoseptal flaps, and 5% with other onlay techniques. Nasoseptal flaps were utilized more frequently in the setting of giant pituitary adenomas (>3cm), medial cavernous sinus wall resection, and high-flow intraoperative CSF leaks. Cases who utilized mucosal grafts had an overall shorter operating time (median: 183 min vs. 240 min; p<0.001). Five postoperative CSF leaks were identified, and therefore, statistical analysis could not be performed for this complication. The effectiveness and morbidity of different sellar reconstruction techniques are comparable. Vascularized flaps were utilized more frequently in the setting of larger tumors and high-flow intraoperative CSF leaks.

The modified Caldwell-Luc approach for treating odontogenic maxillary sinusitis without need for functional endoscopic sinus surgery (FESS). A retrospective study

BackgroundOdontogenic maxillary sinusitis is a common inflammatory condition resulting from the violation of the Schneiderian membrane by conditions arising from the dentoalveolar unit, which includes teeth, their supporting structures, and adjacent tissues. This study aims to evaluate a modified surgical approach for treating this condition. PurposeThe purpose of this study is to measure the frequency of re-treatment of maxillary sinusitis of odontogenic origin following treatment with a modified Caldwell-Luc approach, which involves accessing the maxillary sinus through the canine fossa without creating a counter-opening in the inferior nasal meatus. Study DesignThis retrospective cohort study included 82 cases (83 sinuses) with odontogenic sinusitis treated surgically with the modified Caldwell-Luc technique at the Department of Oral and Maxillofacial Surgery, Poriya Medical Center, between 2014 and 2021. Patients with non-odontogenic sinusitis were excluded. Predictor VariablesAnatomic findings defined as the presence or absence of ostiomeatal complex abnormalities and oroantral communication, as identified through clinical examination and CT imaging. Main Outcome VariablesThe need for retreatment, defined as the requirement for functional endoscopic sinus surgery (FESS) due to persistent signs and symptoms of maxillary sinusitis after the modified Caldwell-Luc procedure, including facial pain/pressure, nasal congestion, purulent nasal discharge, or radiographic evidence of persistent sinus opacification on CT scan, lasting more than 4 weeks despite appropriate medical management. CovariatesCovariates included demographic data (age, sex [male/female as identified at birth]), smoking status, etiologies of odontogenic sinusitis, and surgical conditions. AnalysesDescriptive statistics, Cox proportional hazards regression was used to compute hazard ratios. Kaplan-Meier survival analysis was performed to estimate the probability of remaining FESS-free over time. The level of statistical significance was set at p < 0.05. ResultsThe sample was composed of 82 patients (83 sinuses) with a mean age of 52.3 years (SD 13.5), and 47 (56.6%) were male. Dental implantation and sinus augmentation procedures were the most common etiologies of odontogenic sinusitis (50.6%). The median follow-up time was 6.03 months (IQR: 2.57 - 10.93 months). The incidence rate of FESS requirement was 2.64 per 100 person-months of follow-up. The FESS-free frequency was 89.2% (95% CI: 80.4% - 94.4%). The Kaplan-Meier analysis estimated the probability of remaining FESS-free at 12 months to be 89.1% (95% CI: 79.8% - 94.4%). Patients with OMC abnormalities had a hazard ratio of 2.25 (95% CI: 0.47-10.84, p = 0.31) for requiring FESS, while those with OAC had a hazard ratio of 1.85 (95% CI: 0.46-7.39, p = 0.38). Conclusions and RelevanceThe modified Caldwell-Luc procedure was effective in treating the majority of odontogenic sinusitis cases. FESS may be necessary in a small percentage of cases with persistent symptoms. Further research is needed to identify predictors for FESS requirement. Of note, we recommend that oral and maxillofacial surgery surgeons review sinusitis cases with a FESS surgeon before performing the modified Caldwell-Luc procedure creating the opportunity for simultaneous or closely timed procedures when necessary

Postural Change Assists Surgical Maneuverability During Endoscopic Transsphenoidal Surgery for Pituitary Macroadenoma

In endoscopic transsphenoidal surgery for pituitary adenoma with suprasellar extension, the prolapse of the stretched floppy diaphragma sellae can obstruct the surgical corridor, posing challenges during pituitary surgery. We have introduced a simple postural change technique to mitigate this issue and are sharing our clinical experience. Pituitary surgery is performed on an operating bed where the patient's position can be adjusted. During transsphenoidal pituitary surgery, raising the patient's head to a Fowler's position causes the diaphragma sellae to move upward, while lowering the head to a supine position causes it to descend. This simple adjustment minimizes hindrance from the floppy diaphragm sellae during surgery. We illustrate this technique in pituitary surgery, where diaphragm sellae relocation is necessary. A simple postural change technique effectively manages prolapsed floppy diaphragma sellae, enhancing visualization and surgical accessibility during endoscopic transsphenoidal pituitary surgery.

Transcanal Endoscopic Management of Squamosal Type of Chronic Otitis Media.

Endoscopic middle ear surgery can be utilized to visualize and excise retraction pockets without the need for extensive bone work and removal of lateral bone. To evaluate the role of endoscope in the management of squamosal type of chronic otitis media. A total of 25 adults subjects (male = 12, female = 13) in the age group of 18-55years suffering with chronic otitis media were operated by transcanal endoscopic approach. High resolution computed tomography of temporal bone was done to help identify the anatomy and underlying extent of disease. All patients were operated by transcanal endoscopic technique. The study concluded that the endoscope gives a better visualization of the middle ear and its hidden areas. The extensive bone work and associated cavity related problems can be avoided and normal anatomy can be preserved with the help of endoscopic ear surgery.

The impact of spheno-occipital synchondrosis exposure via extended endoscopic endonasal surgery on midface growth in pediatric patients.

Pediatric extended endonasal procedures pose significant surgical challenges. Lesions from the suprasellar region to the lower clivus necessitate extensive exposure. This study examined whether drilling the spheno-occipital synchondrosis (SOS) to remove the posterior clinoid process and dorsum sellae (DS) for greater exposure affects pediatric midfacial growth. From 2014 to 2020, the authors performed endoscopic endonasal surgery (EES) in 14 patients aged 12 years or younger. The lesions consisted of 11 cases of craniopharyngioma, 1 pituitary neuroendocrine tumor, 1 Rathke's cleft cyst, and 1 Langerhans cell histiocytosis. In 8 of the 14 cases, an extended EES procedure was used by exposing the SOS to remove the posterior clinoid process and DS. Measurement of the central face was based on head MRI before and after surgery. Measuring points were the sellae-nasion (SN) plane, the foremost points of the anterior maxilla (point A), and the maximum concavity point of the mandibular symphysis (point B). The authors measured and evaluated the SNA angle (angle created by the SN plane and the NA [a line connecting point A and the nasion] plane), SNB angle (angle created by the SN plane and the NB [a line connecting point B and the nasion] plane), and the ANB angle (angle created by the NA plane and the NB plane). In addition, a comparison was made with 6 pediatric cases in which transcranial surgery was performed for craniopharyngiomas. In the extended EES group, the average preoperative age was 7 years, and the average postoperative age was 12 years. Mean preoperative angles in this group were 84° (SNA), 80.9° (SNB), and 3.1° (ANB); mean postoperative angles were 83.5° (SNA), 83.9° (SNB), and -0.4° (ANB). In the standard EES group, the average preoperative age was 9 years, and the average postoperative age was 14.5 years. Average preoperative angles in the standard EES group were 83° (SNA), 80.3° (SNB), and 2.7° (ANB); average postoperative angles were 82.7° (SNA), 81° (SNB), and 1.6° (ANB). In the transcranial surgery group, the average preoperative age was 4.5 years, and the average postoperative age was 9.8 years. Mean preoperative angles were 83.8° (SNA), 80.3° (SNB), and 3° (ANB); mean postoperative angles were 83.8° (SNA), 82.6° (SNB), and 1.2° (ANB). The only significant difference between groups was the postoperative ANB angle, which was negative in the extended EES group compared to the standard EES group, indicating the maxilla was positioned posteriorly compared to the mandible. The measurement values of the EES groups and the transcranial surgery group exhibited minimal differences, except for a significant decrease in the postoperative ANB angle in the extended EES group compared with the standard EES group. These results show that extended EES may impact midface growth. Further research is required to understand the long-term impact of SOS exposure.

Comparison of oral pre-medication with clonidine and metoprolol on intraoperative hemodynamics and surgical conditions during functional endoscopic sinus surgery

Background: Functional endoscopic sinus surgery (FESS) is one of the most performed surgical procedures and requires minimal bleeding during the procedure. The success of surgeries is largely dependent on the surgical field, where the presence of significant bleeding is an important factor. Aims and Objectives: The objectives of this study were to evaluate the clinical efficacy of oral clonidine and metoprolol following their pre-medication for induced hypotension during FESS and to assess hemodynamic stability, surgical field quality, and sedation score. Materials and Methods: This is an observational hospital-based study conducted on 60 patients, aged 18–60 years old for FESS assigned by randomization method in two groups including clonidine or metoprolol. Heart rate (HR) and arterial blood pressure are measured after induction, during and end of the surgery. Assessment of bleeding was done by a surgeon who was blinded. Surgical field quality, satisfaction level of the surgeon, Aldrete score, and any side effects were observed. Results: There was no significant difference seen in HR in patients of Group C and Group M in the pre-operative period, after loading the dose of the drug, at extubation (P&gt;0.05). A significant difference was seen in HR with lower mean values in Group C compared to Group M after induction (77.23±12.23), 10 min after induction (69.47±11.99), 20 min after induction (65.63±8.66), 30 min after induction (64±8.32), 40 min after induction (63.77±7.61), and 60 min after induction (63.63±7.89). A significant difference was seen in blood pressure, after loading the dose of the drug, after induction, during surgery monitored every 10 min, at extubation, after extubation monitored every hour for 6 h. Quality of surgical field and surgeon’s satisfaction was better in patients who received clonidine than in those who received metoprolol. Conclusion: Both clonidine and metoprolol can be effectively used for induced hypotension in FESS. Clonidine is better than metoprolol with respect to intraoperative hemodynamics, quality of the surgical field, and surgeon’s satisfaction with the added advantage of sedation, reduced analgesia requirement, and other anesthetic drugs.

Chordoma incidence, treatment, and survival in the 21st century: a population-based Ontario cohort study.

This study estimates the incidence, treatment patterns, and overall survival for patients with chordoma treated in Ontario. A 17-year (2003-2019) population-based cohort study was conducted, including all patients in the Ontario Cancer Registry with histologically proven chordoma. Primary outcomes of interest were age-standardized annual incidence, overall survival, and rates of radiation therapy, chemotherapy, and open resection. A total of 208 patients were diagnosed with chordoma over the study period: 97 patients with skull base chordoma, 37 with mobile spine chordoma, and 65 with sacropelvic chordoma. A total of 133 patients were treated with either open or endoscopic surgery, of whom 99 were also treated with some form of radiation therapy. Across the 17-year study period, the average annual age-standardized incidence was 12.04 cases per 10 million (95% CI 9.31-14.78 cases per 10 million). There was no significant change in the annual incidence rate over the study period (average annual percent change 2.27, 95% CI -1.74 to 6.44; p = 0.25). The odds of receiving radiation therapy or chemotherapy significantly increased by 8% per year (95% CI 1%-16% per year, p = 0.036) over the study period. The odds of receiving open resection significantly decreased by 14% per year (95% CI 8%-20% per year, p < 0.001). The odds of receiving endoscopic surgery among patients with skull base chordoma increased by 38% per year (95% CI 22%-60% per year, p < 0.001), while the odds of patients receiving biopsy alone did not change significantly over the study period (p = 0.684). After diagnosis of chordoma, the 5-, 10-, and 15-year overall survival probabilities were 0.74 (95% CI 0.69-0.81), 0.58 (95% CI 0.51-0.67), and 0.48 (95% CI 0.40 to 0.59), respectively. There was no significant association between hazard of death and year of diagnosis (p = 0.126) or anatomical location (p = 0.712, skull base vs mobile spine chordoma; p = 0.518 skull base vs sacropelvic chordoma). Chordoma is a rare disease with no significant change in the average annual incidence rate between 2003 to 2019. During this time, treatment with less invasive modalities increased, particularly for skull base chordoma. Overall survival exceeds 10 years for many patients, with no change in the hazard of death across the study period.

Investigation of Expectations and Satisfaction After Sinus Surgery for Chronic Rhinosinusitis.

To perform the first mixed-methods analysis of patient expectations and satisfaction after endoscopic sinus surgery (ESS). Semi-structured interviews of subjects undergoing ESS were performed to understand pre-operative expectations and 6-month post-operative satisfaction. Descriptive statistics, logistic regression, and mediation analyses were performed. Quantitative questions were followed by qualitative probes for subjects to expand on quantitative answers. Study sample size was determined by thematic saturation based on qualitative responses. Data visualization was used to triangulate quantitative and qualitative data wherein themes emerged. A total of 52 participants were included in the mixed-method analysis, and 110 were included in the mediation analysis. 56% of participants were male, with an average age of 55.7 (SD ± 2.18). Mean change in SNOT-22 was 20.8 (SD ± 3.74), and 25% of participants did not achieve a minimal clinically important difference (MCID). Of the participants who did not achieve MCID, 79% would still choose to have sinus surgery again. Qualitative interviews revealed multiple preliminary categories describing the patient experience with ESS. Regression analysis showed that the most important predictor of satisfaction was whether pre-operative expectations were met (OR = 3.8, p < 0.001). In mediation analysis, the effect of the clinical outcome on patient satisfaction was completely mediated by pre-operative expectations (indirect effect p = 0.009, direct effect p = 0.17). Patient expectations and satisfaction are important yet understudied measures in CRS and ESS. In ESS, satisfaction with outcome is driven by the fulfillment of pre-operative expectations. Aligning such expectations is the most important intervention a sinus surgeon can perform to maximize success. 4 Laryngoscope, 2024.
