“…Among them bilateral otosclerosis was common. Almost similar finding was observed by Xie J et al 21 Fakir et al 20 found deafness (100%), tinnitus (75%) and vertigo (25%) in their study which was almost similar to our study. Souza et al 1 reported that unilateral (71.2%) otosclerosis was more common than bilateral which was dissimilar to our finding.…”

“…No statistically significant difference (p>0.05) was observed between the groups in pre and postoperative air-bone gap at 2 kHz. Almost similar finding was observed by Xie J et al21 In term of post-operative complications, only chorda tympani injury were found after operation at final follow-up of 3 months. No permanent vertigo was found but immediate post operative vertigo was seen in few cases.…”

Classical and reversal stapedotomy both are exclusively done in otosclerosis but definite information regarding surgical advances, postoperative results, complications and information about how and in which patients these surgical techniques should exclusively be used are a source of continuous discussions. This prospective observational study was conducted in the Department of Otolaryngology-Head & Neck Surgery, Bangabandhu Sheikh Mujib Medical University, Shahbagh, Dhaka from July 2019 to December 2020 o compare the outcomes of classical and reversal stapedotomy in patients with otosclerosis. Total 28 cases of otosclerosis who underwent stapedotomy were divided in to two groups i.e. Group A (classical stapedotomy) & Group B (reversal stapedotomy) with 14 patients in each group. All patients were followed up post-operatively up to 3 months with Pure-tone audiometry (PTA). There is no significant difference between classical and reversal stapedotomy approach in terms of hearing improvement and complications. Chorda tympani injury was the main complication in both the groups. Regarding hearing gain and complications there was no significant difference between classical and reversal stapedotomy approach.

“…In the evaluation of successful stapes surgery, postoperative ABG <10, 15, 20, and 34.5 dB have been reported and accepted in previous studies, with 10 dB considered the most accepted standard (21)(22)(23)(24)(25)(26).…”

Background: Endoscopic stapes surgery (ESS) is widely used to treat patients with otosclerosis, and accumulating evidence demonstrates that endoscopic stapedotomy is feasible and has similar, and often even better, audiological outcomes compared with microscopic stapedotomy. There is a lack of studies on comparisons of ESS and the audiological outcomes of ESS and microscopic stapes surgery (MSS). Therefore, in the present study, we investigated these to figure out if ESS could be a reasonable alternative treatment for otosclerosis patients.Methods: This was a cohort study of 65 patients with otosclerosis who underwent ESS (n=30) or MSS (n=35) between 2017 and 2021, whose diagnoses were mainly based on a history of progressive conductive or mixed deafness over 25 dB in the range of 0.25-4 kHz. Preoperative and postoperative audiological evaluation, including air-conduction (AC), bone-conduction (BC) and air-bone gap (ABG), was carried out using puretone audiometry and performed within 4 weeks before surgery and from 1-14 months after surgery.Results: Thirty ESS and 35 MSS patients were included. There were no significant differences in preoperative and postoperative pure-tone average AC (AC-PTA), BC-PTA, and ABG-PTA between the 2 groups. Postoperative ABG ≤10 dB was found in 8 ESS patients (60%) and 15 MSS patients (43%) (P=0.168).AC and ABG changes in the low-frequency (LF) and mid-frequency (MF) ranges were greater than those in the high-frequency (HF) range for both groups (P<0.05). Although auditory changes between the 2 groups were similar, MSS appeared to have a better BC-PTA compared with ESS (P=0.049). Shifts in ABG and BC were linearly related to preoperative ABG and BC in both groups, and shifts in AC were linearly related to preoperative AC in the ESS group (P<0.05).Conclusions: ESS had a similar audiological outcome compared with MSS, and LF and MF hearing improved to a greater degree than HF hearing in both groups in our study. Based on the linear regression analysis in our study, preoperative ABG-PTA was proved to be the most efficient surgical indicator for both types of stapes surgery for patients with otosclerosis.

“…The inclusion criteria were as follows: (1) patients hospitalized due to suspected otosclerosis between October 2020 and November 2022; (2) no history of chronic otitis media or mastoiditis on the affected side, ear surgery, trauma, or other related ear conditions; (3) pure tone audiometry finding of an air–bone gap more than 10 dB; (4) preoperative HRCT and/or U-HRCT examination at our hospital; (5) stapedotomy was performed with the detailed plan as previously described [ 18 ], and the fixation of the stapes and the movement of the malleus and incus were observed intraoperatively; and (6) postoperative hearing significantly improved. The exclusion criteria included the following: (1) CT evidence of middle ear mastoiditis, cholesteatoma, or tympanic sclerosis; (2) malformation of ossicles or suspected congenital stapes fixation on CT images; (3) retrofenestral otosclerosis on CT images; and (4) for patients who underwent both U-HRCT and HRCT, there was an interval of more than 6 months between the two examinations.…”

Purpose To compare the diagnostic sensitivity of ultra-high-resolution computed tomography (U-HRCT) and HRCT in isolated fenestral otosclerosis (IFO). Methods A retrospective analysis was conducted on 85 patients (85 ears) diagnosed with IFO between October 2020 and November 2022. U-HRCT (0.1 mm thickness) was performed for 20 ears, HRCT (0.67 mm thickness) for 45 ears, and both for 20 ears. The images were evaluated by general radiologists and neuroradiologists who were blinded to the diagnosis and surgical information. The diagnostic sensitivity of U-HRCT and HRCT for detecting IFO was compared between the two groups. Results Excellent inter-observer agreement existed between the two neuroradiologists (Cohen’s κ coefficient 0.806, 95% CI 0.692–0.920), with good agreement between the general radiologists (Cohen’s κ coefficient 0.680, 95% CI 0.417–0.943). U-HRCT had a sensitivity of 100% (40/40 ears) for neuroradiologists and 87.5% (35/40 ears) for general radiologists, significantly higher than HRCT (89.2% [58/65 ears] for neuroradiologists; 41.5% [27/65 ears] for general radiologists) (p = 0.042, p′ < 0.000). General radiologists’ sensitivity with HRCT was significantly lower compared to neuroradiologists (p < 0.000), but no significant difference was observed when general radiologists switched to U-HRCT (p = 0.152). Among the 20 ears that underwent both examinations, U-HRCT detected lesions smaller than 1 mm in 5 ears, whereas HRCT’s sensitivity for neuroradiologists was 40% (2/5 ears), significantly lower than for lesions larger than 1 mm (93.3%, 14/15 ears, p = 0.032). Conclusion U-HRCT exhibits higher sensitivity than HRCT in diagnosing IFO, suggesting its potential as a screening tool for suspected otosclerosis patients. Critical relevance statement Ultra-high-resolution computed tomography has the potential to become a screening tool in patients with suspected otosclerosis and to bridge the diagnostic accuracy gap between general radiologists and neuroradiologists. Key points • U-HRCT exhibits higher sensitivity than HRCT in the diagnosis of IFO. • U-HRCT has a significant advantage in the detection of less than 1 mm IFO. • U-HRCT has the potential to be used for screening of patients with suspected otosclerosis.
