ABSTRACT
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: This research was conducted to investigate the therapeutic effects of tympanoplasty on patients with chronic otitis media with tinnitus and analyze the possible influencing factors for patient prognosis. Methods: This is a pre-post control group study, 86 patients with chronic otitis media were included as the subjects and enrolled into tinnitus group (n = 46) and the non-tinnitus group (n = 40). All patients underwent tympanoplasty under microscope or ear endoscopy. A tinnitus severity and efficacy assessment scale was employed for the evaluation of the severity of tinnitus among the subjects. In addition, tinnitus handicap inventory (THI) was utilized to evaluate disease alleviation. Results: Before treatment, the proportions of the patients with tinnitus at grades I, II, III, IV, and V amounted to 15.22%, 32.61%, 21.74%, 17.39%, and 13.04%, respectively, while they were 30.43%, 45.65%, 13.04%, 8.71%, and 2.17%, respectively 3 months after treatment (P < .05). THI scores for the patients in the tinnitus group before and 3 months after treatment amounted to 17.96 ± 3.66 and 16.21 ± 3.29, respectively (P < .05). After treatment, the air conduction (AC) and bone conduction (BC) thresholds and air-bone gap (ABG) of the two groups apparently declined (P < .05). No statistical significance was detected in the differences in disease classification, disease courses, and whether an electric drill was used among the patients between effective and invalid groups (P > .05). Conclusion: To some extent, tympanoplasty alleviated tinnitus among patients with chronic otitis media and promoted the restoration of hearing. Hence, it is worthy of application in clinical treatment.

OBJECTIVES: 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.

BACKGROUND: As artificial intelligence (AI) is integrating into the healthcare sphere, there is a need to evaluate its effectiveness in the various subspecialties of medicine, including otolaryngology. Our study intends to provide a cursory review of ChatGPT's diagnostic capability, ability to convey pathophysiology in simple terms, accuracy in providing management recommendations, and appropriateness in follow up and post-operative recommendations in common otolaryngologic conditions. METHODS: Adenotonsillectomy (T&A), tympanoplasty (TP), endoscopic sinus surgery (ESS), parotidectomy (PT), and total laryngectomy (TL) were substituted for the word procedure in the following five questions and input into ChatGPT version 3.5: "How do I know if I need (procedure)," "What are treatment alternatives to (procedure)," "What are the risks of (procedure)," "How is a (procedure) performed," and "What is the recovery process for (procedure)?" Two independent study members analyzed the output and discrepancies were reviewed, discussed, and reconciled between study members. RESULTS: In terms of management recommendations, ChatGPT was able to give generalized statements of evaluation, need for intervention, and the basics of the procedure without major aberrant errors or risks of safety. ChatGPT was successful in providing appropriate treatment alternatives in all procedures tested. When queried for methodology, risks, and procedural steps, ChatGPT lacked precision in the description of procedural steps, missed key surgical details, and did not accurately provide all major risks of each procedure. In terms of the recovery process, ChatGPT showed promise in T&A, TP, ESS, and PT but struggled in the complexity of TL, stating the patient could speak immediately after surgery without speech therapy. CONCLUSIONS: ChatGPT accurately demonstrated the need for intervention, management recommendations, and treatment alternatives in common ENT procedures. However, ChatGPT was not able to replace an otolaryngologist's clinical reasoning necessary to discuss procedural methodology, risks, and the recovery process in complex procedures. As AI becomes further integrated into healthcare, there is a need to continue to explore its indications, evaluate its limits, and refine its use to the otolaryngologist's advantage.

OBJECTIVES: To analyze and compare the available data about the outcomes of endoscopic and microscopic type I tympanoplasty. DATA SOURCES: PubMed, Cochrane library Ovid, Scopus, Google scholar, and ClinicalTrials. METHODS: We conducted a meta-analysis in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. We included comparative studies describing type I tympanoplasty, and comparing surgical outcomes of the endoscope with the microscope in terms of efficacy and safety. RESULTS: Our systematic search yielded 22 studies meeting the inclusion criteria and eligible for analysis. The pooled graft uptake rates and audiological results of endoscopic and microscopic tympanoplasty demonstrated non-significant differences. In contrast, endoscopic type I tympanoplasty outperforms microscopic tympanoplasty regarding a highly significant decrease not only in pooled mean operative time but also in the pooled complications rate. CONCLUSIONS: Based on our meta-analysis, the surgical outcomes of endoscope-assisted and microscope-assisted type I tympanoplasty in terms of postoperative hearing outcomes and the graft uptake rate were comparable. On the contrary, operative time and complications rate proved to be significantly reduced with endoscopy compared to microscopy. Hence, the endoscope is as efficient as the microscope in type I tympanoplasty but less invasive, fewer in complications and shorter in operative time.

PURPOSE: 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). METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

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. STUDY DESIGN: Single center blinded randomized controlled trial. MATERIALS AND 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: To analyze and compare the early and late post-operative results of glass ionomer bone cement (GIBC) used in ossiculoplasty. METHODS: The pre-operative, early post-operative (3 months) and late post-operative (> 2 years) audiometric findings, namely the pure-tone average (PTA), bone conduction threshold (BCT) and air-bone gap (ABG) of 40 patients who underwent GIBC ossiculoplasty for different etiologies were analyzed. Early and late results were compared. Also, the patients were grouped in terms of prognostic factors and applied ossiculoplasty techniques, and the results were compared between the groups. RESULTS: There were statistically significant improvements in the pure-tone average and air-bone gap of the patients in the early post-operative period (PTA from 59.60 ± 15.95 to 40.37 ± 17.83 and ABG from 37.12 ± 11.18 to 19.78 ± 10.41, p < 0.001 for both). There were no statistically significant changes in any of the audiometric parameters in the late post-operative period (PTA from 40.37 ± 17.83 to 39.79 ± 17.91, ABG from 19.78 ± 10.41 to 19.32 ± 9.60, BCT from 17.99 ± 12.71 to 18.31 ± 13.99, p > 0.05 for all). Presence of tympanosclerosis was found to be the only prognostic factor to affect the outcome. CONCLUSION: GIBC is a safe and reliable material for ossiculoplasty, which maintains its ability to conduct sound in the long-term follow-up.

PURPOSE: In primary cholesteatoma patients, incus destruction with an intact and mobile stapes is a frequent finding. Different techniques have been described to restore the ossicular chain, including incus interposition, stapes augmentation and type III tympanoplasty. Controversy about postoperative hearing results in open versus closed surgical techniques exist. METHODS: We performed a retrospective analysis of clinical, surgical and audiometric data of patients with primary cholesteatoma surgery operated between 2010 and 2020, and a mobile stapes and one-stage ossicular reconstruction. Pre- and post-operative audiograms were compared for the different surgical groups, mainly focusing on postoperative air-bone gap. Mastoid pneumatization and ventilation was also considered. RESULTS: The mean postoperative air-bone gap (0.5-4 kHz) of the 126 included patients was 20 dB. Hearing after type III tympanoplasty (26 dB) was worse than incus interposition (19 dB) and stapes augmentation (20 dB). Hearing after an open (23 dB) versus closed (19 dB) surgical technique was significantly different. No improvement in air-bone gap was observed for the higher frequencies. CONCLUSION: A residual postoperative air-bone gap should be considered after primary cholesteatoma surgery with intact and mobile stapes. Incus interposition in closed cavity operation is the optimal situation, but open cavity surgery should not be avoided because of hearing. Extent of the disease is prioritized and poorer ventilation before and after surgery may affect postoperative hearing.

A cholesteatoma is an expansion of keratinizing squamous epithelium that enters the middle ear cleft from the outer layer of the tympanic membrane or ear canal. Choleatomas are always treated surgically. Recurrence of the illness presents another challenge for the patient and the surgeon, though. There have been reports of recurrence rates as high as 30% in adults and as high as 70% in children. Here, we describe a case of persistent recurrent otorrhea following revision surgery, along with acquired recurrent cholesteatoma following canal wall down surgery. A 38-year -male with underlying Diabetes Mellitus and Hypertension presented with left scanty and foul-smelling ear discharge for 2 years and left reduced hearing. He was diagnosed with left chronic active otitis media with cholesteatoma for which he underwent left modified radical mastoidectomy, meatoplasty and tympanoplasty in 2017. Five months post operatively, he presented with left otorrhea. However, he defaulted followed up and presented in April 2018 for similar complaints. Otoscopy examination revealed left tympanic membrane perforation at poster superior quadrant of pars tensa and bluish discoloration behind pars flacida. He was diagnosed as recurrent left cholesteatoma and subsequently he underwent left mastoid exploration under general anesthesia in June 2018. Postsurgery, he developed recurrent ear discharge which was treated with topical antibiotics and ear toileting. We report a case of recurrent Cholesteatoma despite canal wall down procedure requiring a second redo procedure and with persistent recurrent otorrhea after the redo procedure.However, this case demonstrates the need for regular follow ups even after a canal wall down procedure for detecting recurrence of disease. Moreover, this case denotes some of the patient factors and surgeon factors involved in disease recurrence. Furthermore, importance of opting for an imaging study in case of high suspicion of the disease.

BACKGROUND: There is ongoing debate over the optimal surgical approach for cholesteatoma treatment1-5. The aim of this review was to determine whether canal-wall down with mastoid obliteration is associated with favourable outcomes compared to either canal-wall down without obliteration or canal-wall up. The primary outcome was cholesteatoma reoccurrence with secondary outcomes including otorrhoea, reoperation and patient-reported outcome measures. METHODS: Medline, Embase, Cochrane databases and clinicaltrials.gov were searched for studies reporting outcomes of patients undergoing primary CWD-MO for cholesteatoma and directly compared with CWD and CWU mastoidectomies. Data were collated and meta-analysis performed. RESULTS: 2379 patients were included from 12 studies that met the inclusion criteria. CWD-MO was found to be associated with significantly less risk of recurrence when compared to CWU (OR = 0.330 (95 % CI 0.191-0.570, p < 0.001). When compared to CWD, CWD-MO was associate with significantly lower incidence of persistent otorrhoea (OR 0.405 (95 % CI 0.232-0.706, p < 0.001) while the rates of recurrence were comparable (OR: 1.231 [95 % CI: 0.550-2.757] p = 0.613). Otorrhoea rates between CWD-MO and CWU were equivalent as was reoperation. Quality of life and hearing outcomes were variably reported. CONCLUSIONS: This systematic review demonstrates that CWD-MO technique achieves lower recurrence rates comparable to CWD approaches and superior to CWU, while offering improved long-term control of otorrhoea. The final procedural choice should be decided based on surgeon experience, skill set and individual patient factors. To address the risk of selection bias, a randomised controlled trial is needed to answer this important research question.

PURPOSE: Compare the audiological results and postoperative outcomes of the endoscopic approach versus the endaural microscopic approach for treatment of attic cholesteatomas, using a randomized prospective model. MATERIALS AND METHODS: Eighty patients were consecutively enrolled in the study and randomized into two groups of treatment of 40 patients: Group A -tympanoplasty with a microscopic endaural approach; Group B -tympanoplasty with an exclusive trans-meatal endoscopic approach. Preoperative, intraoperative and postoperative outcomes were evaluated. Hearing was assessed preoperatively and at 1 month, 3 months and 6 months after surgery in both groups. RESULTS: There were no differences in the parameters analyzed (CT findings, patient age, disease duration, intraoperative cholesteatoma characteristics,) between the group A and B patients. No statistical difference between the two groups regarding hearing improvement, abnormal taste sensation, dizziness, post-operative pain and healing times emerged. Graft success rate was 94.5 % and 92.1 % for MES and ESS respectively. CONCLUSION: Both microscopic and exclusively endoscopic endaural approaches offer similar and excellent results in the surgical treatment of attic cholesteatomas.

INTRODUCTION: There are several factors that seem to affect the surgical success rate of tympanoplasty, one of them being the pneumatization of the contralateral mastoid. In the current literature, several studies have been published with classification proposals for temporal bone pneumatization pattern. This study aims to evaluate the role of mastoid air cell extension in relation to the sigmoid sinus in predicting the surgical success of tympanoplasty. MATERIAL AND METHODS: This case-control study was performed on patients diagnosed with chronic otitis media (COM) who underwent type I tympanoplasty. The study group did not close the tympanic membrane, or there was a retraction or lateralization of the graft. The control group consisted of patients with surgical success. RESULTS: No statistically significant difference was found between groups regrading age, gender, perforation side/type, previous nasal surgery, and the presence of chronic otitis media in contralateral ear. A statistically significant difference was found when groups were compared in relation to the degree of pneumatization of the contralateral ear (p = 0.046), and this relationship does not seem to be influenced by age. CONCLUSION: To predict surgical success in terms of tympanic membrane closure in tympanoplasty, classification of contralateral ear pneumatization degree using the sigmoid sinus as a reference seems to be a valid and easy to apply method, and makes it possible to restrict the evaluation of pneumatization to the mastoid, a cell complex that does not seem to change with age.

PURPOSE: Endoscopic type I tympanoplasty was originally introduced in the 1990s and the extensive spread of this practice can be easily observed. The conventional technique performed involves the repair of a tympanic membrane perforation and is defined as microscopic type I tympanoplasty. The aim of this study is the comparison of quality-of-life (QoL) outcomes with endoscopic to that with microscopic type I tympanoplasty. METHODS: All patients, or in the case of children with the aid of a parent, were asked to complete a novel QoL questionnaire drafted by our study group. The analysis was performed with descriptive statistics-mean, SD and relative frequency-and with a mixed model (generalized least squares fit). A two-sided p value of < 0.05 was regarded as statistically significant. RESULTS: A total of 83 patients completed the questionnaire, 38 in the endoscopic group and 45 in the microscopic group. Every question represented a different. A statistically significant result was found in favor of the endoscopic approach regarding average hospitalization rate (p = 0.003) and cosmetic outcomes (p = 0.015). No statistically significant difference was otherwise observed between the groups. CONCLUSIONS: Based on our prospective cohort study, the QoL outcomes of endoscopic type I tympanoplasty in terms of postoperative pain, headache, nausea, vomiting, dizziness, taste disorder and hearing were comparable to the microscopic type I tympanoplasty. In regard to cosmetics, an increase in desirable results was achieved in the endoscopic group, particularly the average hospitalization rate proved to be statistically significantly lower than in the microscopic group.

OBJECTIVES: The comparative efficacy of microscopic tympanoplasty (MT) and endoscopic tympanoplasty (ET) has been widely studied to some extent through meta-analyses. However, most studies on learning curve comparisons between the two surgeries were performed by experienced ET surgeons. We compared the surgical outcomes of MT and ET and evaluated the difference of learning curve between ET and MT performed by a single unskilled, in both MT and ET, surgeon. DESIGN: A total of 91 patients underwent ET and MT at a tertiary hospital. We reviewed the patients' medical records and analyzed all findings, including otoscopic pictures, pure tone audiometry (PTA) before and after surgery, and operation records. All operations were performed by a single otologist who had an experience of a year of otology fellowship at a tertiary university hospital. We compared the demographic and clinical characteristics, including age, sex, admission duration, and audiological outcomes before and after surgery. We also assessed the difference in the decrease in operation time. RESULTS: Among 91 patients, 44 were in the ET group and 47 were in the MT group. The mean age was 51.15 years, and 37 (40.7%) were men. Eighty-two (90.1%) patients were administered local anesthesia. Graft failure was observed in 19 (20.9%) patients, and the mean postoperative follow-up duration was 66.42 days. There were no statistically significant differences in age, sex, affected side, graft failure rate, and operation time between the ET and MT groups. There was a significant improvement in air conduction hearing and air-bone gap after surgery in both groups. Bone conduction hearing did not change before and after the surgery in either group. However, the improvement in air condition and reduction in the air-bone gap did not differ between the two groups. Multivariate linear regression analysis showed that there were no significant variables that affected operation time among age, sex, operation method (ET or MT), anesthesia, graft material, and technique. The spline regression analysis showed the decrease in operative time in ET was significantly faster than MT in the period from 8th to 19th cases. CONCLUSIONS: The surgical outcomes of ET are comparable to those of MT in terms of operation time, graft uptake, and postoperative hearing results, even in surgeons who are not experienced with both MT and ET. The operation time of ET was longer than that of MT in the early phase, and the decrease in the operating time was significantly faster in ET than in MT. Both MT and ET reached a plateau in the operation time, and this plateau appeared to be similar in both surgeries.

OBJECTIVES: To conduct a systematic review and meta-analysis of all randomized controlled trials (RCTs) that examined the efficacy of dry versus wet temporalis fascia graft among patients undergoing type-I tympanoplasty. METHODS: Web of Science, Scopus, PubMed, and CENTRAL databases were screened from inception until July 2022. The Cochrane risk of bias tool was used to assess the quality of included RCTs. The outcomes were summarized as risk ratio (RR) or mean difference (MD) with 95% confidence interval (CI) in a random-effects model. RESULTS: Eight RCTs with 989 patients (dry group = 514 and wet group = 475) were included. The overall quality was 'low', 'some concerns', and 'high' risk of bias in five, two, and one RCT(s), respectively. There were no significant differences between both groups regarding the surgical success rate (n = 8 RCTs, RR 0.99, 95% CI [0.95, 1.03], p = 0.6), audiological success rate (n = 5 RCTs, RR = 0.93, 95% CI [0.73, 1.13], p = 0.48), mean difference in pure tone average (n = 2 RCTs, MD = 2.73 Hz, 95% CI [- 2.31, 7.77], p = 0.29), and mean difference in graft placement time (n = 3 RCTs, MD = - 2.18 min, 95% CI [- 5.11, 0.76], p = 0.15). However, the mean difference in operative time was significantly lower in favor of the wet compared with the dry temporalis fascia group (n = 2 RCTs, MD = 2.95 min, 95% CI [- 1.80, 4.11], p < 0.001). The surgical success rate was not significantly different between both groups according to the tympanic membrane perforation size and site. CONCLUSIONS: The type of temporalis fascia graft (dry or wet) did not influence the clinical outcomes of type-I tympanoplasty.

PURPOSE: To conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) that evaluated the surgical outcomes of type-1 tympanoplasty with and without gelfoam middle ear packing. METHODS: PubMed, CENTRAL, Scopus, Web of Science, and Google Scholar databases were screened from inception until October 2022. The included RCTs were evaluated for risk of bias, and the quality of each outcome was assessed according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. RESULTS: Nine RCTs with 773 participants (gelfoam = 381 and non-gelfoam = 392) were analyzed. The overall study quality varied: low risk (n = 4 RCTs), some concerns (n = 3 RCTs), and high risk (n = 2 RCTs). There were no significant differences between both arms regarding the graft uptake rate (moderate certainty), hearing improvement rate (moderate certainty), type of impedance audiometry (moderate certainty), and ear discharge (low certainty). The mean change in air-bone gap was significantly higher in the non-gelfoam arm compared with the gelfoam arm (low certainty). However, the non-gelfoam group had superior hearing improvement in only the early postoperative period (i.e., one month); however, after two, three, and six months, there were no significant differences between both arms. The rate of ear fullness was significantly higher in the gelfoam arm compared with the non-gelfoam arm (moderate certainty). CONCLUSION: Among patients undergoing type-1 tympanoplasty, the surgical outcomes did not significantly differ between both arms. The practice of middle ear packing with gelfoam needs to be standardized.

PURPOSE: The purpose of this study was to compare the effectiveness of endoscopic and microscopic approaches for butterfly cartilage graft inlay tympanoplasty regarding anatomical and hearing outcomes through a systematic review and meta-analysis. METHODS: A search of PubMed, Embase, MEDLINE, and Virtual Health Library was performed from inception to July 3rd, 2021, using keywords, such as tympanoplasty, cartilage graft, and inlay technique. Data from articles that met inclusion criteria were extracted by two authors independently. The PRISMA statement was followed. RoB-2 and ROBINS-I tools were used to assess risk of bias. The primary outcome was tympanic membrane closure rate. The secondary outcome was improvement of the air-bone gap. RESULTS: Five studies were included, one randomized clinical trial and four retrospective cohorts, in which a total of 318 patients were included. Graft take rate was 91.3% in the endoscopic group and 93.6% in the microscopic group (RR 0.98; 95% CI 0.93-1.03; I2 0%; P = 0.68). Four studies provided data about the secondary outcome, all showing significant reductions in air-bone gap, ranging from 5.7 to 11.0 in the endoscope group and from 5.8 to 11.6 in the microscope group, with a mean difference between groups of 0.85 (95% CI - 0.79 to 2.48). CONCLUSION: Although the overall evidence of the included studies was low, endoscopic and microscopic butterfly cartilage graft inlay tympanoplasties have similar results on anatomical and hearing outcomes, making the selection between such approaches an individual choice for the surgeon.

PURPOSE: The European and Japanese system for cholesteatoma classification proposed an anatomical differentiation in five sites. In stage I disease, one site would be affected and in stage II, two to five. We tested the significance of this differentiation by analyzing the influence of the number of affected sites on residual disease, hearing ability and surgical complexity. METHODS: Cases of acquired cholesteatoma treated at a single tertiary referral center between 2010-01-01 and 2019-07-31 were retrospectively analyzed. Residual disease was determined according to the system. The air-bone gap mean of 0.5, 1, 2, 3 kHz (ABG) and its change with surgery served as hearing outcome. The surgical complexity was estimated regarding the Wullstein's tympanoplasty classification and the procedure approach (transcanal, canal up/down). RESULTS: 513 ears (431 patients) were followed-up during 21.6 ± 21.5 months. 107 (20.9%) ears had one site affected, 130 (25.3%) two, 157 (30.6%) three, 72 (14.0%) four and 47 (9.2%) five. An increasing number of affected sites resulted in higher residual rates (9.4-21.3%, p = 0.008) and surgical complexity, as well poorer ABG (preoperative 14.1 to 25.3 dB, postoperative 11.3-16.8 dB, p < 0.001). These differences existed between the means of cases of stage I and II, but also when only considering ears with stage II classification. CONCLUSION: The data showed statistically significant differences when comparing the averages of ears with two to five affected sites, questioning the pertinence of the differentiation between stages I and II.

PURPOSE: The relatively new technique of trans-canal endoscopic ear surgery (TEES) when compared to microsurgery for ossiculoplasty has advantages of better visualization and no external incision but also has the disadvantage of being a one-handed procedure. Our study aimed to compare audiometric outcomes following ossiculoplasty performed via TESS with results of microsurgery. MATERIALS AND METHODS: Data from a prospective audit of 157 consecutive patients who underwent ossiculoplasty by a single otologist from 2009 to 2018 was analyzed. TEES was introduced in the department in 2014; therefore, all patients before this period underwent microsurgery. Patients were classified by surgical approach, TEES, or microsurgery. Audiological outcomes were recorded at 3 and 12 months postoperatively and compared to pre-operative levels. Other variables included were the condition of stapes and reconstruction material used. RESULTS: Of the 157 cases, 50 were TEES and 107 were microsurgery (81 microscope only and 27 combined with endoscope). There was statistically significant improvement (p < 0.001) in AC (43.4 dB pre-operatively, 36.2 dB postoperatively), BC (20.3 dB pre-operatively, 17.6 dB postoperatively), and ABG (21.8 dB pre-operatively, 16.7 dB postoperatively) in the total cohort. Both groups achieved an ABG better than 20 dB; 72% in TEES, 73% in the microscopic group, and there was no significant difference. There was no change in hearing at 12 months when compared to 3 months. No statistically significant difference was noted based on stapes condition, type of material used for ossiculoplasty, or tympanic membrane graft. CONCLUSION: TEES is safe and as effective as microsurgery in ossiculoplasty with possibly much less pain and morbidity.
