Intraoperative Compound Action Potentials as a Predictor of Postoperative Cortical Auditory Evoked Potentials in Cochlear Implant Users.

Electrically evoked cortical auditory evoked potentials (ECAEPs) are central brain responses to auditory stimuli that correlate with post-operative cochlear implant (CI) hearing outcomes. They differ from electrically evoked compound action potentials (ECAPs) which are peripheral responses that can be elicited intraoperatively and may also predict CI hearing outcomes. It is not known to what degree ECAP and ECAEP responses are associated with each other. Such a correlation, if present, may allow for an earlier and more accurate prediction of post-operative hearing outcomes. This retrospective study involved 42 adult CI users. Threshold levels and amplitude growth function slopes of intraoperative ECAPs were compared to the latencies and peak-to-peak amplitudes of postoperative ECAEP responses at three different cochlear electrode array sites (apical, medial, and basal). A weak positive relationship was found between intraoperative ECAP thresholds and ECAEP N1-P2 peak-to-peak amplitude (r=0.301, p=0.005). Time between ECAP and ECAEP measurements was weakly correlated with P1-N1 peak-to-peak amplitude (r=0.321, p=0.002) and ECAEP N1-P2 peak-to-peak amplitude (r=0.340, p=0.001). ECAP amplitude growth function (AGF) slopes varied by electrode location (χ²=26.701, df = 2, p=0. 000002). These results suggest that intraoperative ECAP responses do not robustly predict postoperative ECAEP responses, providing caution against the use of ECAPs as a predictive tool for CI hearing outcomes.

A study on the efficacy of combined surgery in advanced-stage congenital cholesteatoma with canal-wall-up surgery.

This study aimed to compare the outcomes of patients with advanced congenital cholesteatoma who underwent microscopic or endoscope-combined Canal Wall Up Tympanomastoidectomy (CWUT) in our clinic and to determine the contribution of endoscope use in reducing recurrence/residual rates. In this retrospective study, the data of individuals who underwent microscopic or combined endoscopic surgery between 2008 and 2022 in our clinic were scanned from the database. Demographic data, preoperative computed tomography (CT) findings, preoperative and postoperative hearing results, operation and intraoperative status of the ossicles, duration of surgery, postoperative follow-up period, recurrence and residual disease status during follow-up were investigated. The data of 37 pediatric cases operated in our clinic were included in the study. All of the included cases were Potsic Stage 4 patients who underwent CWUT. The mean age of the operated individuals was 8.7 years (5-12 years) and the mean follow-up period was 47.3 months (12-112 months). 19 cases were performed microscopically only, 2 recurrences and 5 residuals were detected. 18 cases were performed combined and 1 recurrence and 1 residual was found. In this study, it was determined that using an endoscope together with a microscope in congenital cholesteatoma cases, decreased the rate of recurrence and residual disease by protecting the external auditory canal in patients with advanced mastoid invasion.

Validity of endoscopic ossiculoplasty immediately after its introduction for ossicular chain disruption

BackgroundTranscanal endoscopic ear surgery (TEES) reportedly requires a long learning curve and may be associated with more complications and longer operative times than microscopic ear surgery (MES). In this study, we aimed to examine the usefulness and validity of TEES for ossicular chain disruption in the early stages of its introduction in our institution.MethodsTEES was performed on 11 ears (10 with congenital ossicular chain discontinuity and 1 with traumatic ossicular chain dislocation), and MES was performed with a retroauricular incision on 18 ears (6 with congenital ossicular chain discontinuity and 12 with traumatic ossicular chain dislocation) in a tertiary referral center. Postoperative hearing results, operative times, and postoperative hospital length of stay were retrospectively reviewed. The Mann–Whitney U test and Fisher’s exact test was performed to compare variables between the TEES and MES groups. Pre- and postoperative air- and bone-conduction thresholds and the air–bone gap of each group were compared using the Wilcoxon signed-rank test. The Mann–Whitney U test and Wilcoxon signed-rank was performed to compare the pre- and postoperative air–bone gaps between the diagnoses.ResultsNo significant differences in the postoperative air-conduction thresholds, bone-conduction thresholds, air–bone gaps, or incidence of air–bone gap ≤ 20 dB were observed between the TEES and MES groups. The air-conduction thresholds and air–bone gaps of the TEES group significantly improved postoperatively. The air-conduction thresholds and air–bone gaps of the MES group also significantly improved postoperatively. No significant difference was observed in the operative times between the groups (TEES group: median, 80 min; MES group: median, 85.5 min). The TEES group had a significantly shorter postoperative hospital stay (median, 2 days) than the MES group (median, 7.5 days).ConclusionsTEES was considered appropriate for the treatment of ossicular chain disruption, even immediately after its introduction at our institution. For expert microscopic ear surgeons, ossicular chain disruption may be considered a suitable indication for the introduction of TEES.

Canal-wall up cholesteatoma surgery with mastoid obliteration leads to lower rates of disease recurrence without affecting hearing outcomes.

The primary objective was to determine whether obliteration of the epitympanic area and mastoid cavity during canal wall up (CWU) cholesteatoma surgery reduces the rate of recurrent and residual cholesteatoma compared to not obliterating the same area. The secondary objective was to compare postoperative hearing outcomes between both techniques. A retrospective cohort study was conducted in a tertiary referral center. One-hundred-fourty-three ears were included of patients (≥18y) who underwent a CWU tympanomastoidectomy for cholesteatoma with or without bony obliteration between January 2015 and March 2020 in the University Medical Center Utrecht. The median follow-up was respectively 1.4 (IQR 1.1-2.2) vs. 2.0 years (IQR 1.2-3.1) (p = 0.013). All patients underwent CWU tympanomastoidectomy for cholesteatoma. For 73 ears bone dust, Bonalive® or a combination was used for obliteration of the mastoid and epitympanic area, the rest of the ears (n = 70) were not obliterated. In accordance with the Dutch protocol, included patients are planned to undergo an MRI scan with diffusion-weighted imaging (DWI) one, three and five years after surgery to detect recurrent or residual cholesteatoma. The primary outcome measure was recurrent and residual cholesteatoma as evaluated by MRI-DWI and/or micro-otoscopy and confirmed by micro-otoscopy and/or revision surgery. The secondary outcome measure was the postoperative hearing. In this cohort, the group treated with canal wall up tympanomastoidectomy with subsequent bony obliteration (73 ears, 51.0%) had significantly lower recurrent (4.1%) and residual (6.8%) cholesteatoma rates than the group without obliteration (70 ears, 25.7% and 20.0%, respectively; p < 0.001). There was no significant difference between both groups in postoperative bone conduction thresholds (mean difference 2.7 dB, p = 0.221) as well as the mean air-bone gap closure 6 weeks after surgery (2.3 dB in the non-obliteration and 1.5 dB in the obliteration group, p = 0.903). Based on our results, a canal wall up tympanomastoidectomy with bony obliteration is the treatment of choice, since the recurrent and residual disease rate is lower compared to the group without obliteration. The bony obliteration technique does not seem to affect the perceptive or conductive hearing results, as these are similar between both groups.

Otic Capsule Demineralization and Hearing Outcome of Stapes Surgery for Osteogenesis Imperfecta in Comparison With Otosclerosis.

To assess the location/number of otic capsule demineralization and hearing outcomes of stapes surgery (SS) for osteogenesis imperfecta (OI) compared with otosclerosis (OS). This study included 11 and 181 consecutive ears from 6 and 152 patients with OI and OS, respectively. Demineralization loci observed as hypodense area of the otic capsule were examined using high-resolution computed tomography. All patients underwent SS. Locations of the hypodense areas were classified into the anterior oval window, anterior internal auditory canal, and pericochlear area. The location/number of hypodense areas and preoperative/postoperative hearing parameters were correlated. Postoperative hearing outcome was evaluated 12 months after surgery. Hypodense area was more frequently observed in OI (9 of 11 ears [81.8%]) than in OS (96 of 181 ears [53.0%]), with significant differences. Multiple sites were involved in 81.8% OI and 18.8% OS patients, showing significant differences. Preoperative air conduction (AC), bone conduction, and air-bone gap (ABG) were 48.9 ± 17.8, 28.0 ± 11.3, and 20.7 ± 8.4 dB, respectively, in OI and 56.2 ± 13.5, 30.5 ± 9.9, and 26.4 ± 9.7 dB, respectively, in OS, demonstrating greater AC and ABG in OS than in OI. Postoperative AC (31.3 ± 20.5 dB), ABG (10.6 ± 10.0 dB), and closure of ABG (12.1 ± 4.7 dB), that is, preoperative ABG minus postoperative ABG of OI, were comparable to those of OS (AC, 30.9 ± 13.3 dB; ABG, 7.0 ± 7.4 dB; closure of ABG, 20.1 ± 11.6 dB). OI ears showed more severe demineralization of otic capsule than OS ears. However, favorable hearing outcomes could be obtained through SS for OI and OS ears.

Mucosal-Type Chronic Otitis Media: Clinical Predictors of Postoperative Success.

Chronic otitis media (COM) remains a global disease, a burden, and a challenge. Predicting its treatment's postoperative success based on clinical presentation has not been reported, particularly for the mucosal (tubotympanic/safe) type. A prospective descriptive study of patients with mucosal-type COM was done to identify clinical predictors of improved postoperative hearing outcomes and successful graft uptakes. Among the 110 ears studied, tympanoplasty was performed in 76 and corticalmastoidectomy with tympanoplasty in 34, based on six weeks of discharge-free or persistent discharge, respectively; all were treated with postoperative intranasal steroid spray. Eustachian tube dysfunction was noted in 96.4%. All patients with a history of ear discharge over five years had ossicular discontinuity, and those with persistent discharge had nonpatent aditus. Normal postoperative hearing was attained in most patients with less than one year of ear discharge.Surgical intervention within a year achieved normal hearing and graft success of 100% with type I tympanoplasty using the fascia alone in discharge-free ears and cortical mastoidectomy with tympanoplasty using cartilage-fascia graft in discharging ears, despite Eustachian tube dysfunction. In the latter group, graft success in type II tympanoplasty was 76.9%. Ear discharge is the prime predictor of postoperative success in mucosal-type COM, as its duration and persistence dictate the time and type of surgical intervention.Duration of more than five years is directly proportional to pre-operative hearing loss with ossicular involvement and inversely proportional to postoperative hearing improvement, necessitating early surgical intervention, despite it being the mucosal or "safe type." Ear discharge-free for six weeks is an indicator of tympanoplasty. Persistent ear discharge, despite nonotogenic confounders, suggests aditus nonpatency, indicates the need for cortical mastoidectomy, and necessitates achieving its patency along with tympanoplasty. A surgical decision-making algorithm for the best possible surgical outcome in the chronic mucosal type of OM is also suggested.

Predictors of hearing outcomes in patients undergoing ossicular chain reconstruction in a developing country.

Objective: To explore the social and clinical factors that predict audiometric outcomes in patients undergoing ossicular chain reconstruction. Methods: A retrospective analytical cohort study was conducted, including patients 18 years of age or older with a history of chronic otitis media (COM) and/or any of its complications, who underwent ossicular chain reconstruction with Partial Ossicular Replacement Prosthesis (PORP) or Total Ossicular Replacement Prosthesis (TORP), at Hospital San José and Hospital infantile Universitario de San José between 2012 and 2020. We excluded patients with ossicular chain malformations and those with incomplete information. Information about sociodemographic and clinical factors was collected. Additionally, the surgery findings information was analyzed using the Ossiculoplasty outcome parameter staging ( OOPS) index. Results: A total of 35 adult patients who underwent ossicular chain reconstruction were retrospectively studied. An improvement was evidenced in the Preoperative Pure-Tone Average (PTA) and postoperative PTA (p-value=0.036), as well as in the pre and postoperative air-bone gap (ABG) (p-value &lt; 0.01). A moderate correlation coefficient was found between the OOPS index and the postoperative PTA (p= 0.429), and between the OOPS index and the postoperative (ABG) (p= 0.653). Conclusion: We found that a higher OOPS score is correlated with worse hearing outcomes postoperatively, and there was no association between the demographic or pathologic factors with a worse postoperative hearing outcome. Therefore, OOPS index can predict audiometric outcomes in patients undergoing ossicular chain reconstruction in a developing country, regardless of the demographic or pathologic factors.

Endoscopic Transcanal Stapes Surgery: Our Audiological and Surgical Results

Endoscopic Transcanal Stapes Surgery: Our Audiological and Surgical Results&#x0D; Adem Bora, Tuğberk Salık&#x0D; Sivas Republic University Health Services Application and Research Hospital, Ear Nose Throat Clinic, Sivas, Turkey&#x0D; &#x0D; ABSTRACT&#x0D; Aim: The aim of this study is to investigate the intraoperative and postoperative results of endoscopic stapes surgery performed at our institution.&#x0D; &#x0D; Methods: A total of 25 patients with 28 ears (14 right, 14 left ears) who underwent endoscopic stapes surgery between 2018 and 2022 were analyzed for postoperative hearing outcomes and surgical complications at the 6-month follow-up.&#x0D; &#x0D; Results: The average age of the patients was 43.16 years (range, 24-63 years), and 64.0% of the patients were female. The median preoperative air-bone gap decreased from 30.36 dB hearing level (HL) to 18.95 dB HL after surgery (P &lt; 0.001). The postoperative air-bone gap was 10 dB or lower in 8 patients (28.6%), 11-20 dB in 10 patients (35.7%), and more than 20 dB in 6 patients (21.4%). Intraoperative complications included only tympanic membrane ruptures in one patient, which resolved during the initial follow-up. Postoperatively, 10.7% of the subjects complained of changes in taste sensation. One patient developed facial paralysis responsive to steroid treatment one week after surgery.&#x0D; &#x0D; Conclusion: Endoscopic surgery is particularly suitable for stapedial disorders. Endoscopic stapes surgery is minimally invasive and suitable for surgical training, as surgical anatomy can be easily understood, and both the surgeon and assistant can observe the procedure from the same monitor. The operation should only be performed by experienced surgeons due to the need for single-handed operation and the lack of stereoscopic vision.&#x0D; &#x0D; Keywords: Stapes; Stapedectomy; Outcomes; Endoscopic ear surgery

To detach or not to detach the umbo in type I tympanoplasty: functional results.

To compare the audiological outcomes, tympanic membrane (TM) healing rates and complication rates in patients undergoing endoscopic underlay and over-under tympanoplasty type I (TTI). The study includes 95 patients who underwent endoscopic TTI in the period between 2018 and 2023: 56% of the patients had the underlay technique and 41% had the over-under technique. Data regarding pre- and postoperative hearing, perforation characteristics, surgical procedures, graft types and complications were retrospectively analyzed. Audiometrical assessment included air conduction (AC) and bone conduction (BC) pure tone averages (PTA) and air-bone gap (ABG), pre- and postoperatively. Both underlay and over-under techniques significant improved AC PTA, with a mean ABG improvements of 5.9 dB and 7.2 dB, respectively. There was no significant difference in BC PTA between pre- and post-operative, indicating no inner ear damage in both techniques. The over-under technique showed a significantly higher TM closure rate (94.4%) compared to the underlay technique (80.6%). Complications were rare, with only one case of TM lateralization requiring revision surgery. Endoscopic TTI is an effective treatment in improving auditory function in chronic middle ear diseases. In our cohort, the detachment of the umbo does not negatively influence the postoperative hearing results and does not increase rate of complications. Moreover, the over-under technique demonstrates superior TM closure rates, making it a valuable option for specific cases. However, future prospective studies with larger sample sizes and longer term follow-up are needed to validate these findings and provide more comprehensive insights.

Surgical and Audiological outcomes of Wet versus Dry Temporalis Fascia Graft in Type 1 Tympanoplasty

Objectives: Evaluate the surgical success and postoperative hearing outcome of type 1 tympanoplasty using temporalis fascia graft in its wet versus its dry fashion.&#x0D; Methods: A prospective randomized comparative study which was conducted in Sulaimanyah otorhinolaryngology &amp; head and neck surgery centre between October 2018 and November 2019 on patients with sign and symptom of tympanic membrane perforation who underwent type1 tympanoplasty in 2 groups in whom wet graft used in one group, and dry graft used in the other group, these patient followed up after 3 month for graft take and postoperative hearing.&#x0D; Results: Of the 29 patients included in the study in 15 of them dry graft used and the graft take was 86.7% and in 14 of the wet graft used and the take rate was78.6%, postoperative mean hearing gain was 14.07 dB in the dry graft group and 12 dB in the wet graft group, all cases in both group had improvement in hearing (P value= 0.001), but neither wet nor dry was better than the other (P value=0.345). Graft take and hearing gain in different site and size of perforations were not significant, graft take rate was 100% in small size and 50% in subtotal perforation, hearing gain was 14.50 dB for subtotal perforation and 9.50 dB in small size perforation, mean time of wet graft group with 75.36 minutes were shorter significantly than the dry graft with 95 minutes with (P value=0.001).&#x0D; Conclusion: The Nature of the temporalis fascia not affect the outcome type 1 tympanoplasty, and temporalis fascia is a good graft material regarding the success rate and hearing gain, however the wet Temporalis fascia graft use may shorten the operation time.

Hearing Results after Transmastoid Superior Semicircular Canal Plugging for Superior Semicircular Canal Dehiscence: A Meta-Analysis.

The transmastoid plugging of a superior semicircular canal is considered a safe and effective technique for the management of superior semicircular canal dehiscence (SSCD). The aim of this meta-analysis is to assess the postoperative hearing outcomes after the transmastoid plugging of the superior semicircular canal. Search method and data sources: A systematic database search was performed on the following databases until 30 January 2023: MEDLINE, Embase, Cochrane Library, Web of Science, CINAHL, ICTRP, and clinicaltrials.gov. A systematic literature review and meta-analysis of the pooled data were conducted. We also included a consecutive case series with SCDS for those who underwent transmastoid plugging treatment at our clinic. We identified 643 citations and examined 358 full abstracts and 88 full manuscripts. A total of 16 studies were eligible for the systematic review and 11 studies for the meta-analysis. Furthermore, 159 ears (152 patients) were included. The postoperative mean air conduction threshold remained unchanged (mean difference, 2.89 dB; 95% CI: -0.05, 5.84 dB, p = 0.58), while the mean bone conduction threshold was significantly worse (mean difference, -3.53 dB; 95% CI, -6.1, -0.95 dB, p = 0.9). The transmastoid plugging technique for superior semicircular canal dehiscence syndrome, although minimally worsening the inner ear threshold, is a safe procedure in terms of hearing preservation and satisfactory symptom relief.

Managing cholesteatomas with labyrinthine fistula.

A retrospective study (2011 to 2018) was conducted to evaluate the management of cholesteatomas with labyrinthine fistulae (LFs), clinical characteristics and postoperative hearing outcomes in a hospital. Demographic data of patients with primary middle ear mastoidectomies for cholesteatoma were extracted. Preoperative high-resolution computed tomography (HRCT) temporal bone and intraoperative findings, and hearing levels preoperatively and postoperatively were evaluated. Of the middle ear cholesteatomas, 15.6% (n = 14) of ears were complicated by LF. HRCT scans showed 92.9% sensitivity and 94.7% specificity in the identification of LFs. Intraoperative findings of LFs include stapes erosion (78.6%), malleus erosion (78.6%), incus erosion (92.9%), dehiscence of tegmen tympani (28.6%) and tympanic facial canal (64.3%). Compared to the non-LF group, the LF group showed significantly higher incidence of stapes erosion (P < 0.001), tegmen tympani dehiscence (P = 0.016) and semicircular canal dehiscence (P < 0.001). Matrix was removed completely in 85.7% (n = 12) and was left behind in 14.3% (n = 2) of ears. Also, 21.5% (n = 3) had preoperative dead ears. Postoperative hearing results had a mean follow-up time of 2.1 (standard deviation 1.5, range 0.14-4.84) years. In the matrix removal group (n = 9), 77.9% had unchanged hearing levels, 11.1% showed improvement and 11.1% showed decrease in hearing levels. The matrix preservation group (n = 2) had deteriorated hearing levels. Preservation of hearing in LFs is possible with cautious matrix removal. Despite matrix preservation to preserve hearing in large LFs, our patients' hearing deteriorated postoperatively. Longer follow-up of hearing with matrix preservation may show poorer hearing outcomes.

Experiences with endoscopic ear surgery of a German tertiary hospital for otolaryngology

The aim of this article is to report on the integration of endoscopic ear surgery (EES) into daily clinical practice. In amonocentric prospective study, the endoscopy unit was set up during even weeks over aperiod of 10 months and the procedure was primarily started endoscopically via atransmeatal approach. In odd weeks, the endoscopy was omitted. A total of 60 procedures in 59patients were evaluated. Points of comparison were intraoperative vision, incision-suture time, postoperative hearing outcome, and postoperative otoscopic findings. With the exception of the facial nerve (p = 0.15 Mann-Whitney U‑test), the EES showed significantly improved visualization of all areas in the middle ear. The incision-suture times were similar in both methods. If bimanual placement of an ossicular prosthesis was necessary, the incision-suture time increased disproportionately (MES: 57.18 ± 9.7 min, EES: 76.83 ± 24.99 min; p = 0.019, *). There were no statistically significant changes related to hearing outcomes when comparing EES with the microscopic technique. There were no postoperative complications in the EES surgery group. Integration of EES proved to be successful and advantageous in a real patient collective at this location.

A comparative study of hearing outcome in cholesteatoma surgery canal wall up versus canal wall downmastoidectomy in 100 patients

Cholesteatoma is a well-demarcated sac of keratinizing squamous epithelium in the temporal bone, which is commonly characterized as “skin in the wrong place. The major goal of surgery for cholesteatoma is to make the ear safe and dry with increasing concern of the hearing outcome of patients. Two main surgical techniques employed are Canal Wall down (CWD) and Canal Wall up Mastoidectomy (CWU). In the current study, an attempt would be made to evaluate which technique would be better for achieving disease clearance with favorable hearing outcome and dry ear.1. To evaluate the hearing results following CWU and CWD surgery in patient with cholesteatoma.2. To decide surgical approach according to extension of disease.Materials and Methods:This is a prospective study involving 100 patients with cholesteatoma who had undergone CWD and CWU surgery over the period of 3 years.The choice of mastoidectomy, CWD or CWU, was the decision of the surgeon, after completely evaluating the patient, preoperatively and intraoperatively. All cases were followed up &amp; assessed by autoscopic examination &amp; PTA for minimum of 3 months. In the CWD group, mean hearing gain, in 3 months was 12±1.73dB. In the CWU group, hearing gain in 3 month postoperative period was 18±2.06 dB. Also the hearing gain between the two groups was compared and it was found to be statistically significant for the 3 months (p=0.0002) postoperatively; signifying that there was a comparable difference for CWU over CWD mastoidectomy in the matter of Hearing Gain. SNHL was also seen post operatively in both group. Total 3 (6%) patient in CWU had SNHL post operatively in comparison to 7(14%) patients in CWD. From our study results, we think that CWU is superior to the CWD surgery in cases of cholesteatoma because of good post-operative hearing outcome as well as less complication and law morbidity. CWD surgery should be used in cases of extensive cholesteatoma, mental retardation, not sure about follow up and inadequate middle ear space cases.

The impact of waiting time on hearing outcome and patients’ satisfaction after cholesteatoma surgery

Background Cholesteatoma is a formation of epithelium mass in the middle ear. Surgery aims to prevent complications while maintain or improve hearing. Aims/Objectives To determine if waiting time until cholesteatoma surgery affects hearing outcome and patients’ satisfaction. Material and Methods A retrospective cohort study performed at the only Ear Nose Throat clinic in one county in Sweden. Sixty concomitant surgeries, both first time and revisions, were included. Results Of the 60 surgeries, 33 (55%) were performed within a 3-month period. The mean waiting time was 1.4 months. In the remaining 27 cases, the mean waiting time was 8.6 months. Both groups had preoperatively similar air conduction pure tone average (AC PTA4), 47.3 dB and 47.0 dB respectively. The mean AC PTA4 gain was greater in the group with waiting time ≤3 months (8.6 dB) compared to the >3 months group (1.2 dB, p = 0.040). The patients’ satisfaction was lower in the latter group, but the difference was not statistically significant. Conclusions This study indicates that longer waiting time to cholesteatoma surgery has a negative impact on postoperative hearing results but not on patients’ satisfaction. Significance The outcome of this study suggests that waiting time to surgery can be a factor determining postoperative hearing results.

Comparison of temporalis muscle fascia and cartilage grafts for primary type 1 tympanoplasty: a meta-analysis of randomized controlled trials.

To compare the efficacy and safety of temporalis fascia (TF) with cartilage grafts for primary type 1 tympanoplasty in chronic otitis media (COM) patients. Computerized search was performed in MEDLINE, Embase, and CENTRAL. Eligible for inclusion were randomized controlled trials (RCTs) comparing TF and cartilage grafts in individuals with non-cholesteatoma COM and intact ossicles requiring type 1 tympanoplasty. Primary outcomes were graft success and hearing improvement, measured by the air-bone gap (ABG) closure. The secondary outcome was the occurrence of complications. Standardized mean differences (SMD) and odds ratios (OR) with 95% confidence intervals were calculated. Eighteen RCTs that enrolled 1273 participants were found eligible. Data were reported at follow-up periods ranging from 6weeks to 24months. The pooled effect estimate revealed a higher and statistically significant graft success favoring cartilage grafts at 12months (OR = 2.24, 95% CI 1.33-3.78) and 24months (OR = 2.96, 95% CI 1.18-7.43). There was no significant difference between both grafts in post-operative ABG closure across all follow-up periods (6weeks to 12months). Compared to TF, primary type 1 cartilage tympanoplasty offers better graft uptake rates and comparable postoperative hearing outcomes for COM patients.

The assesment of intraoperative use of mesna in canal wall-up cholesteatoma surgery - preliminary report.

&lt;b&gt;Introduction:&lt;/b&gt; Surgery is still the method of choice in chronic otitis media with cholesteatoma. Except for some specific clinical situations, classic canal wall up technique (CWU), remains a gold standard as a primary treatment in most departments. Unfortunately, the risk of recurrence in such an approach is estimated at 9 to even 70%. This fact prompts researchers to look for ways to reduce those unfavourable statistics. One of the recognized methods supporting the removal of cholesteatoma is the intraoperative use of mesna (sodium 2-mercaptoethanesulfonate). This synthetic sulphur compound disrupts disulfide bridges in polypeptide chains, thanks to which it facilitates matrix preparation.&lt;/br&gt;&lt;/br&gt; &lt;b&gt;Aim:&lt;/b&gt; To evaluate the effect of intraoperative use of mesna on the treatment outcomes in patients with chronic otitis media with cholesteatoma operated on by means of the canal wall up technique (CWU).&lt;/br&gt;&lt;/br&gt; &lt;b&gt;Material and methods:&lt;/b&gt; 459 surgical reports of patients with middle ear cholesteatoma were analyzed. In total, 52 adult patients with no history of previous ear surgery operated on by means of the CWU technique by the same experienced otosurgeon with all follow-up data available were included in the study. Twenty-six were operated on with the use of mesna (mesna group) and 26 by means of the classic CWU technique (control / no-mesna group). There were 28 women and 24 men with a mean age of 41 years.&lt;/br&gt;&lt;/br&gt; &lt;b&gt;Main Outcome Measure(s):&lt;/b&gt; Postoperative hearing results and cholesteatoma recidivism rate.&lt;/br&gt;&lt;/br&gt; &lt;b&gt;Results:&lt;/b&gt; Overall recidivism rate was 21.15 %. It was higher in the no-mesna (26.9%) than in the mesna group (15.4%) - although the outcomes were better in the mesna group, the difference was not statistically significant (P = 0.49715). Hearing gain was better in the mesna than in the no-mesna group (10 dB vs 7 dB), but the difference was not statistically significant (P = 0.20089).&lt;/br&gt;&lt;/br&gt; &lt;b&gt;Conclusions:&lt;/b&gt; Our preliminary results show that mesna reduces recidivism rates in patients with cholesteatoma. Further study with the analysis of a larger group of patients is needed to prove it statistically.

Tympanoplasty Healing Outcomes With Use of Postoperative Otic Quinolones.

Tympanoplasty usually results in tympanic membrane perforation (TMP) closure, but healing may be suboptimal (e.g., excess scarring). Factors that have been linked to impaired TM healing have become widely adopted (especially, postoperative use of quinolone ear drops). The aim of this study is to assess the frequency of suboptimal tympanoplasty healing with the use of otic quinolones postoperatively. Retrospective chart review. Tertiary care facility. One hundred patients undergoing tympanoplasty for TMP. Tympanoplasty +/- canalplasty. Healing complications (e.g., granulation tissue, TMP, myringitis, bone exposure, lateralization, anterior blunting, medial canal fibrosis, and canal stenosis) and hearing loss. Charts were reviewed for postoperative healing issues and hearing outcomes at 1 to 2 years postoperatively. TMP closure was found in 93.2%, but 34.2% had healing issues at 1 to 2 years postoperatively, with 20.6% having adverse healing outcomes (perforation (6.9%), granulation tissue (6.9%), medial fibrosis (4.1%), and myringitis, bone exposure, and webbing (all 1.4%). Another 13.7% had notable postoperative issues, such as protracted otorrhea (11.0%), otitis externa (9.6%), otitis media (1.4%), and atelectasis (2.7%). No medical, surgical, or patient factors impacted outcomes. Average air-bone gap at 1 to 2 years did not differ between patients with and without healing issues and patients with other postoperative issues ( p = 0.5). Suboptimal healing is common after tympanoplasty. There may be significant opportunity to improve post-tympanoplasty healing beyond improving the TMP closure rate.

The effect of bony obliteration on quality of life after tympano-mastoidectomy surgery: A prospective observational controlled cohort study.

The study's primary objective was to compare the quality of life (QoL) and external auditory canal (EAC) hygiene among patients who underwent bony mastoid obliteration or meatoplasty after canal wall down (CWD) mastoidectomy. A prospective, observational, controlled cohort study was conducted at our tertiary referral university hospital. Twenty-eight patients older than 16 years of age with chronic otitis media who underwent CWD mastoidectomy were included. Two cohorts were followed: CWD mastoidectomy followed by mastoid obliteration (Group 1, n = 14) and CWD mastoidectomy followed by meatoplasty (Group 2, n = 14). The main outcome measures of total COMBI score (postoperative 6-month QoL) and EAC hygiene were compared between the groups. The average age of the patients was 36.14 (12. 22) years; 15 (53.6%) were female and 13 (46.4%) were male. There were no differences in demographic variables, preoperative findings, or COMQ-12 (preoperative QoL) scores between groups. The average COMBI score of Group 1 (49.0 [8.66]) was not significantly different from Group 2 (46.79 [7.76]) (p = .482). Poor EAC hygiene was observed in eight (57.1%) patients in Group 2 and three (21.4%) patients in Group 1 (p = .06). In Group 1, no resorption of graft material was observed in 10 (71.4%) patients, minor resorption was observed in three (21.4%) patients, and significant resorption was observed in one (7.1%) patient. There were no significant differences in audiological findings between groups (p > .05). There were no significant differences regarding short-term postoperative QoL, EAC hygiene, or hearing outcomes between patients who underwent bony mastoid obliteration or meatoplasty after CWD mastoidectomy. 1b (individual prospective cohort study).

Impact of Intraoperative Findings on Hearing in Revision Ear Surgery.

Hearing results after chronic ear surgery encompass recurrence, localization and extent of cholesteatoma, type of surgery, ossiculoplasty methods, but rarely interpret intraoperative findings. This study aimed to analyze the impact of intraoperative findings in revision tympanomastoidectomy in predicting postoperative hearing. This was a retrospective non-randomized cohort of 101 patients treated for recurrent chronic otitis media by tympanomastoidectomy. The patients' demographics, localizations of disease recurrence and perioperative hearing results were analyzed. Logistic regression showed that presence of tympanic perforation (p=0.036), ossicular chain damage (p=0.006), were negatively associated with improved hearing postoperatively. Attic cholesteatoma was associated with better postoperative hearing (p=0.045). Presence of tympanic perforation (p=0.050), alongside perifacial localization of imflammation (p=0.021) and ossicle destruction (p=0.013) were associated with worse postoperative hearing results. Multivariate analysis confirmed that tympanic perforation (p=0.040, F=4.401), and ossicular chain involvement (p=0.025, F=5.249), were consistent negative predictors of hearing improvement, while postoperative deterioration of hearing was associated with tympanic perforation (p=0.038, F=4.465) and facial nerve dehiscence (p=0.045, F=4.160). Comparison of postoperative revision tympanomastoidectomy hearing outcomes revealed significant positive reductions in air-bone gap values, primarily at low and mid frequencies. Postoperative hearing results at high frequencies are not affected by revision surgery.
