UNASSIGNED: To compare endoscopic versus microscopic method for tympanoplasty in terms of Graft uptake and hearing outcome.
UNASSIGNED: A randomized prospective observational study was done. 60 patients who came to ENT outpatient of tertiary care teaching hospital requiring operative intervention for inactive mucosal chronic otitis media. Randomization was done and patients divided into two groups with Group A undergoing endoscopic tympanoplasty and Group B undergoing microscopic tympanoplasty. Post operative graft uptake and hearing improvement were compared between both groups. Intraoperatively visualization of middle ear structures, surgeon\'s comfort, duration of surgery, post operative pain, giddiness was compared. in both the groups.
UNASSIGNED: Total 60 patients got randomly divided in the two groups. There was no difference in terms post op graft success rate and post operative hearing improvement in both the groups Intra operative visualization of middle ear structures better in the endoscopic group and also the surgical time was significantly less in endoscopic group.
UNASSIGNED: On comparing endoscopic versus microscopic tympanoplasty in patients of mucosal chronic otitis media, success rate in terms of graft acceptance and hearing improvement was equal between both groups. However, visualisation of middle ear structures was better in endoscopic method. Operating time was shorter in endoscopic tympanoplasty.

OBJECTIVE: The aim of the current study was to evaluate the efficacy of PRF-augmented fascia tympanoplasty versus cartilage tympanoplasty in repair of large TM perforations.
METHODS: This randomized clinical trial included 156 patients with dry large tympanic membrane perforations. Patients were randomly allocated into 2 groups, cartilage tympanoplasty group (n = 77) and platelet rich fibrin (PRF) augmented tympanoplasty group (n = 79). Graft take rates, hearing outcomes, operative time, and postoperative complications were documented and compared.
RESULTS: Graft take rate was 96.1% in the cartilage group and 93.7% PRF group with no statistically significant difference. Operative time was significantly longer in the cartilage group. No differences in the hearing outcomes and postoperative complications were reported.
CONCLUSIONS: Application of PRF on the fascia in tympanoplasty promotes healing of the tympanic membrane. PRF is safe, cheap, readily available, and easily prepared and applied. It increases the success rates of large tympanic membrane perforations without the need for cartilage grafts.

OBJECTIVE: This study aimed to establish the minimal clinically important difference (MCID) and assess the responsiveness of the Chinese version of Zurich Chronic Middle Ear Inventory (ZCMEI-21-Chn).
METHODS: Prospective multicenter study.
METHODS: Four Chinese tertiary referral centers admitting patients nationwide.
METHODS: 230 adult patients with chronic otitis media (COM) undergoing tympanoplasty.
METHODS: Patients were required to complete the ZCMEI-21-Chn to measure health-related quality of life both preoperatively and postoperatively. An anchor-based method was used to determine the MCID of the derivative cohort by including the Global Rating of Change Questionnaire as an anchor. The generalizability and consistency with functional outcomes of the MCID estimates were externally examined in a validation cohort using a receiver operating characteristic curve analysis.
RESULTS: A total of 161 and 69 patients were included in the derivative and validation cohort. The mean preoperative and postoperative ZCMEI-21-Chn total scores were 28.4 (standard deviation [SD] 14.5) and 17.5 (SD 12.6). The mean change in ZCMEI-21-Chn score was 10.9 (SD 14.3, p < 0.001). The MCIDs of the ZCMEI-21-Chn for improvement and deterioration were estimated at 13 (SD 13.0) and -7 (SD 12.9), accordingly. For patients who have reported an improved health-related quality of life, a cutoff value of 15.6 dB HL for elevation of the air-conducted hearing threshold was noticed. However, change of clinical importance judged according to MCID and Japan Otological Society criteria disagreed with each other, notably with a Cohen\'s kappa ( κ ) of 0.14 ( p = 0.21) in the validation cohort.
CONCLUSIONS: This study is the first to establish the MCID of a COM-specific questionnaire in Chinese. For the COM population undergoing surgical intervention, MCID values of 13 for improvement and -7 for deterioration are recommended. The results were externally validated to be generalizable to nationwide usage, yet distinguishable from the audiological criteria. The availability of the MCID greatly adds to the clinical utility of the ZCMEI-21-Chn by enabling a clinically meaningful interpretation of its score changes.

OBJECTIVE: This study aimed to compare the efficacy of labetalol and lidocaine in tympanoplasty surgery, specifically evaluating their impact on hemodynamic changes and perioperative outcomes.
METHODS: A randomized controlled trial was conducted with 64 patients scheduled for tympanoplasty. Patients were randomly assigned to receive either 0.5-2 mg/min labetalol or 1.5 mg/kg/h lidocaine 1% to achieve controlled hypotension during surgery. The efficacy of the drugs was assessed by comparing the Mean Arterial Pressure (MAP), surgeon\'s satisfaction, time to target MAP, bleeding volume, postoperative pain scores, the need for analgesic medication in recovery, sedation, and other additional parameters.
RESULTS: The hemodynamic parameters showed a similar trend over time in both the labetalol and lidocaine groups. The median bleeding volume in the labetalol group (10 cc) was lower than that in the lidocaine group (30 cc), although this difference was not statistically significant (p = 0.11). Similarly, surgeon\'s satisfaction level, pain intensity, and sedation level in the recovery room did not show statistically significant differences between the two groups (p > 0.05). The duration of surgery, recovery stay, and extubation time also did not significantly differ between the groups. Both medications took approximately the same time (20 min) to reach the target MAP and exhibited comparable hemodynamic responses (p > 0.05).
CONCLUSIONS: Both labetalol and lidocaine effectively achieved controlled hypotension during tympanoplasty surgery, thereby improving surgical conditions. The choice of medication should be based on individual patient characteristics and the anesthesiologist\'s judgment.
METHODS: II.

UNASSIGNED: Tympanoplasty is the most common operation performed by an Otolaryngologist worldwide.Type 1 tympanoplasty involves repair of pars tensa of tympanic membrane, when the middle ear is normal. The most widely used method is underlay technique using temporalis facia. In buttonhole tympanoplasty, the temporalis fascia is anchored to the handle of malleus through the buttonhole.
UNASSIGNED: To compare and analyze graft uptake and hearing outcome in button hole technique and underlay technique.
UNASSIGNED: It is a comparative study done at tertiary care center, where patients suffering from tubotympanic type of chronic otitis media with medium sized perforation with moderate conductive hearing loss, within age group of 18-60 years,were selected.
UNASSIGNED: In Button hole tympanoplasty group the mean hearing gain was 9.3dB, and 8.17 dB in Underlay tympanoplasty group which was statistically significant (p < 0.05) but P value between Button hole and Underlay tympanoplasty was not statistically significant.With regard to graft uptake 96.7% showed graft uptake in Buttonhole tympanoplasty group and in underlay tympanoplasty the graft uptake was 93.3%.
UNASSIGNED: Buttonhole technique is better in terms of graft uptake since the graft is anchored to the handle of malleus, and postoperatively medialisation of graft and other complications like lateralization of graft, epithelial pearl formation and anterior blunting is prevented. Both techniques are good in terms of hearing improvement for chronic otitis media with medium sized perforation with moderateconductive hearing loss.

OBJECTIVE: The purpose of this study was to evaluate the safety and tolerability of VELNEZ (Datt Mediproducts Pvt. Ltd., New Delhi, India) as a space-occupying dressing for controlling hemorrhage after ear surgery.
METHODS: A total of 21 patients were included in an open-label, interventional, single-arm post-marketing surveillance study to investigate the safety and efficacy of the VELNEZ ear pack. The patients were questioned for collecting data related to the subject\'s safety and comfort, adverse events, site assessment, and otoscopic examination from discharge day to last follow-up (eight follow-up visits) at regular intervals. The standardized questionnaires for VELNEZ tolerability (pain/pressure effect, infection, and general satisfaction) were used after ear surgery.
RESULTS:  The average hemorrhage control time was 1.08 ± 0.16 minutes. None of the subjects reported moderate pain at any of the study visits following surgery. This biodegradable ear pack had an average disintegration time of 25.4 days in the ear cavity. No postoperative adverse events or serious adverse events were observed.
CONCLUSIONS: VELNEZ is safe and effective as a space-occupying dressing pack after ear surgery and is well-tolerated by patients.

BACKGROUND: Hearing loss caused by middle ear malformations is treated by tympanoplasty to reconstruct the acoustic conduction system. The mobility of the ossicles plays a crucial role in postoperative success. However, identifying the location of ossicular malformation based solely on preoperative audiograms is challenging due to the complex relationship between fixation location, deformity levels, and ossicular mobility.
METHODS: Middle ear finite element models for simulating ossicular malformations were created, and the results were compared with the actual preoperative audiograms.
RESULTS: This approach objectively diagnosed ossicular fixation and disarticulation, bypassing traditional criteria reliant on physician examination or imaging.
CONCLUSIONS: This study suggests that future research should focus on developing a diagnostic framework utilizing large-scale data.

OBJECTIVE: The objective of this study was to compare the graft outcomes and complications of two endoscopic perichondrium-cartilage graft techniques for repairing large perforations.
METHODS: Single center blinded randomized controlled trial.
METHODS: 61 large perforations more than 50% of TM area were prospectively randomized to undergo the free perichondrium and free cartilage graft group (FPFC, n = 31) or perichondrium partial attachment the cartilage graft group (PPAC, n = 30). The primary outcome measures were the operation time; secondary outcome measures were the graft success rate and hearing gain at 12 months postoperatively and postoperative complications.
RESULTS: All patients completed follow-up of 12 months. The mean operation time was 38.2 ± 2.3 min in the FPFC group and 37.4 ± 5.6 min in the PPAC group (P = 0.658). At postoperative 3 months, the graft success rates were 96.7% in the FPFC group and 93.3% in the PPAC group (P = 0.976). At postoperative 12 months, the graft success rates were 96.7% in the FPFC group and 83.3% in the PPAC group (P = 0.182). However, the residual and re-perforation rate with no infection was 0.0% (0/31) in the FPFC group and 16.7% (5/30) in the PPAC group (P = 0.056). No significant between-group differences were observed pre- (P = 0.842) or post- (P = 0.759) operative air bone gap (ABG) values or mean ABG gain (P = 0.886). However, granular myringitis has been noted in 6.5% in the FPFC group and in 3.3% in the PPAC group.
CONCLUSIONS: This study suggested that 12-month graft success and hearing gain were comparable between the perichondrium free and partial attachment the cartilage graft techniques, nevertheless, partial attachment technique could increase residual and re-perforations.

OBJECTIVE: The study aimed to evaluate the long-term clinical, radiological, and functional results for subtotal petrosectomy and cochlear implant surgery with closure of the external auditory canal and fat obliteration.
METHODS: We retrospectively included all consecutive cases of simultaneous subtotal petrosectomy and cochlear implant surgery performed at a tertiary referral center between 2009 and 2016 using the same surgical technique. All patients underwent postoperative high-resolution computed tomography (HRCT) and annual audiological assessments. A 5-year minimum clinical, radiological, and audiological follow-up was performed. The early and late postoperative results were compared. The main outcome measures were complications, postauricular retraction, fat graft reabsorption, and audiological outcomes.
RESULTS: Twenty-nine procedures performed in 23 patients (six bilateral) met the inclusion criteria. The mean age of the patients was 67 ± 13.4 years and mean follow-up duration was 7.5 ± 2 years. At follow-up, postauricular retraction was detected in 24 cases (82.8%), including five cases (17.1%) with subcutaneous protrusion of implant and array. Fat graft volume was significantly reduced at late-HRCT in terms of maximum diameter (2.24 ± 1.0 cm vs 3.69 ± 0.7 cm; p < 0.0005) and surface area (1.88 ± 1.2 vs 4.24 ± 1.6 cm2, p < 0.0005). Six patients had extracochlear electrodes at late-HRCT (3/6 had an increased number of extracochlear electrodes), with a lowering of this group\'s performance of - 15% (p < 0.005) in the follow-up speech comprehension test.
CONCLUSIONS: Subtotal petrosectomy with cochlear implantation is an effective long-term technique in selected cases. Fat grafts showed significant reabsorption at long-term follow-up with reaeration of the middle ear spaces. Prolonged clinical and radiological follow-up is recommended for monitoring implant performances and late complications.
