A labyrinthine fistula is a severe complication of middle ear cholesteatoma that can cause profound sensorineural hearing loss and vertigo. However, there is no consensus regarding the transition to postoperative hearing. Although hearing deteriorates gradually with a delay in some cases of labyrinthine fistula, insufficient consideration has been given to this point. We examined perioperative changes in cases of middle ear cholesteatoma with labyrinthine fistulas. We retrospectively reviewed the medical records of 578 patients with middle ear cholesteatoma who underwent tympanoplasty at our hospital between 2016 and 2021. Patients with labyrinthine fistulas were selected; their perioperative bone-conduction hearing was assessed. Fistula depth was determined following the classification reported by Dornhoffer et al. The hearing was compared preoperatively, early postoperatively (3-6 months), and 1 year postoperatively. Forty-eight patients (8.3%) had labyrinthine fistulas. Regarding depth, 21 cases were type I, 14 were type IIa, 3 were type IIb, and 10 were type III. Preoperative bone-conduction hearing was significantly poor in invasion type IIb or deeper cases. Cases with type IIb or deeper fistulas, multiple fistulas, or vertigo deteriorated postoperatively. Type III cases or those with multiple fistulas deteriorated further from the early postoperative period to 1 year postoperatively. Concerning frequency, 500 and 2000 Hz showed a delayed deterioration. This is a valuable report of delayed hearing loss after surgery in patients with a labyrinthine fistula. This change is associated with the labyrinthine fistula\'s depth and multiple fistulas-this is important during preoperative counseling of patients undergoing surgery.

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.

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.

BACKGROUND: This study aimed to explore the impacts of different middle-ear mucosal conditions on the outcomes of type I tympanoplasty.
METHODS: 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.
RESULTS: 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.
CONCLUSIONS: 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.

OBJECTIVE: To evaluate the anatomic and functional outcomes of type1 tympanoplasty with endoscopic modified butterfly cartilage-perichondrium technique.
METHODS: In our modification, perichondrium was elevated circumferentially till the attached part of the composite graft was approximately same size and shape of the perforation, cartilage was trimmed based on the perforation but 0.5 mm larger. Cartilage portion of the graft was placed medial to the edge of the perforation, then perichondrium was rolled out and draped on the circumferential raw surface of remaining tympanic membrane around.
RESULTS: At 4 months postop, the anatomic integrity rate of the tympanic membrane perforation for small & medium sized perforation and large sized perforation group were 100 % and 94 % (p > 0.05). For the small & medium perforation group, the mean pre and 4 months postop ACs were 30 ± 8 dB and 18 ± 6.4 dB (p < 0.01). The mean pre and 4 months postop ABGs were 19 ± 11 dB and 9 ± 3 dB (p < 0.01). For the large perforation group, the mean pre and 4 months postop ACs were 43 ± 12.5 dB and 21.5 ± 7 dB (p < 0.01). The mean pre and 4 months postop ABGs were 34 ± 8.5 dB and 12.5 ± 6 dB (p < 0.01). The differences of mean 4 months postop ACs and mean 4 months postop ABGs between the two groups were not significant (p > 0.05).
CONCLUSIONS: Compared to the conventional inlay butterfly cartilage tympanoplasty technique, large or marginal perforations can be sealed more securely by this modification.

OBJECTIVE: The aim is to investigate the influence of an active otitis media on the success rate of tympanoplasty in patients with a chronic otitis media (COM) and a tympanic membrane perforation.
UNASSIGNED: PubMed, Embase and the Cochrane Library.
METHODS: The inclusion criteria were studies on closure rates of tympanoplasty performed in COM patients of any age with a tympanic membrane perforation caused by COM. The exclusion criteria were studies on patients undergoing concomitant mastoidectomy, ossicular chain reconstruction, tuboplasty, adenoidectomy, revision tympanoplasty, patients with perforations due to other conditions than COM, and letters to editors, commentaries, conference abstracts and case reports. The included articles were critically appraised using the QUIPS tool. Data on tympanic membrane closure rate were extracted, odds ratio (OR) and 95% confidence intervals (CI) of the closure rate with a wet versus a dry ear were calculated.
RESULTS: The search was performed on 1 February 2023. Of 4671 articles, 16 studies were included and critically appraised. Of these observational studies (nine prospective, seven retrospective), with a total of 1509 patients (dry ear group n = 1003; wet ear group n = 506), two studies stated a significant difference in success rate, one in favour of a dry ear and one in favour of a wet ear at time of surgery. All other studies did not show a statistically significant difference. Overall, the risk of bias was considered moderate to high.
CONCLUSIONS: We found no significant prognostic value of having an active otitis media during tympanoplasty on tympanic membrane closure rates. Because the overall risk of bias was considered moderate to high, no strong conclusions can be made. To be able to answer this question with higher levels of evidence, high-quality prospective or randomized studies are needed.

BACKGROUND This prospective study aimed to compare outcomes and hearing improvement in 51 patients with adhesive otitis media following endoscopic and microscopic tympanoplasty. MATERIAL AND METHODS Between April 2021 and April 2022, 51 patients diagnosed with pars tensa retraction and hearing loss who underwent endoscopic and microscopic cartilage tympanoplasty were included in the study (endoscopic tympanoplasty group: 26 patients, microscopic tympanoplasty group: 25 patients). Pure-tone audiometric data (0.5, 1, 2, and 4 kHz), air-bone gap (ABG), and postoperative graft intake were compared. RESULTS Hearing gain in the ABG was significant in both groups (p<0.05). When the groups were compared for mean hearing gain in the ABG, the difference was significant (p<0.05). The postoperative ABG in the endoscopic group was significantly smaller than that in the microscopic group. When the postoperative air conduction threshold was evaluated, there was no significant difference between the 2 groups at 4 kHz, whereas a significant difference was observed in the endoscopic tympanoplasty group at 0.5, 1, and 2 kHz. Postoperative graft failure and otorrhea were not observed in any of the patients. CONCLUSIONS Pars tensa retractions and adhesive otitis media show comparable outcomes with both endoscopic and microscopic techniques. In endoscopic tympanoplasty, better visualization allows for better hearing outcomes. The endoscopic method, characterized by a wide field of view and a less invasive approach, enhances access to retraction limits.

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:To analyze the surgical efficacy and safety of tympanoplasty with and without mastoidectomy for the treatment of active simple chronic suppurative otitis media（CSOM）, and to investigate whether mastoidectomy can be avoided in tympanoplasty for active CSOM. Methods:The clinical data of 55 patients（55 ears） with active CSOM were retrospectively analyzed. Based on the development of the mastoid process and the upper tympanic chamber, patients who met the criteria for wall-up mastoidectomy were classified as group A （30 patients）, and underwent tympanoplasty combined with wall-up mastoidectomy. Patients who did not meet the criteria for wall-up mastoidectomy were classified as group B（25 cases）, and underwent tympanoplasty with the opening of the middle and upper tympanic chambers and sinus drainage after partial removal of the shield plate bone. The survival rate of tympanic membrane grafts, hearing before and after surgery, and complications such as reperforation were compared between the two groups at 3 months postoperatively. Results:The overall postoperative tympanic membrane survival rate of patients with active CSOM was 96.4%（53/55）, including 96.7% in group A; 96.0% in group B. There was no significant difference in the tympanic membrane survival rate between the two groups（P>0.05）. The postoperative mean air-bone gap（ABG） was significantly reduced in both groups compared with the preoperative period, but there was no significant difference in ABG gain between the two groups（P>0.05）. No patients experienced serious adverse conditions such as peripheral facial paralysis, cerebrospinal fluid leakage, or sensorineural deafness after surgery. Conclusion:Microscopic tympanoplasty with patency of the middle and upper tympanic chambers and tympanic sinus drainage can be used to treat active simple chronic otitis media with satisfactory tympanic membrane viability and hearing improvement efficacy. This approach reduces patient trauma, prevents complications such as skin depressions in the mastoid area due to abrasion of the mastoid bone, and shortens the waiting time before surgery.

Objective:To investigate the changes in hearing threshold of the acquired primary cholesteatoma of the middle ear with different degrees of eustachian tube dysfunction after balloon eustachian tuboplasty. Methods:This retrospective study included forty cases with middle ear cholesteatoma and eustachian tube dysfunction who underwent open mastoidectomy + tympanoplasty + balloon eustachian tuboplasty were enrolled. All patients were admitted from November 2020 to April 2022. The preoperative eustachian tube score of 0-2 were defined as the lower group, and the scores of 3-5 were defined as the higher group. Pure tone audiometry was measured preoperatively and 1, 3, 6 and 12 months postoperatively. The average value of bone conduction threshold and air conduction threshold of 250-4 000 Hz were calculated, and the air-bone gap was calculated simultaneously. SPSS 25.0 was used for statistical analysis. P<0.05 was considered statistically significant. Results:In the lower group, the air conduction threshold and air-bone gap at 3 months postoperatively were significantly decreased in comparison with those preoperatively（P<0.05），as was the air-bone gap at 6 months postoperatively（P<0.05）. In the higher group, the air conduction threshold and air-bone gap were significantly decreased at 3, 6 and 12 months postoperatively（P<0.05）. Conclusion:The air conduction threshold and air-bone gap of patients with the acquired primary cholesteatoma of the middle ear and eustachian tube dysfunction were significantly decreased after eustachian tube balloon dilatation. Hearing improvement lasted longer in patients with slight eustachian tube dysfunction.
