Introduction Otosclerosis is a primary disease of the temporal bone that leads to stapes ankylosis. Hearing loss is the main symptom. Treatment includes surgery, medical treatment, and sound amplification therapy alone or in combination. Objective To evaluate the functional outcomes of patients with clinical diagnosis of otosclerosis undergoing primary stapes surgery in a teaching institution. Method Retrospective descriptive study. Results A total of 210 ears of 163 patients underwent stapes surgery. Of the 163 patients, 116 (71.2%) underwent unilateral surgery and 47 (28.8%) underwent bilateral surgery. Six of the 210 operated ears had obliterative otosclerosis. The average preoperative and postoperative air–bone gap was 32.06 and 4.39 dB, respectively. The mean preoperative and postoperative bone conduction threshold was 23.17 and 19.82 dB, respectively. A total of 184 (87.6%) ears had a residual air–bone gap <10 dB, and 196 (93.3%) had a residual air–bone gap ≤15 dB. Two patients (0.95%) had severe sensorineural hearing loss. Conclusion Stapes surgery showed excellent functional hearing outcomes in this study. This surgery may be performed in educational institutions with the supervision of experienced surgeons.

Hearing Outcomes

The objective of this study was to determine hearing outcomes in patients undergoing stapes surgery with a preoperative air-bone gap (ABG) <21.25 dB. Patients with a unilateral or bilateral preoperative ABG <21.25 dB undergoing primary stapes surgery were identified from a database of all stapes surgeries performed in a tertiary center over 15 years. A total of 254 ears met the inclusion criteria. The primary outcome measure was the degree of closure of the preoperative ABG. A secondary outcome measure was improvement in bone-conduction thresholds at 4 kHz. All patients underwent stapes surgery under local anesthesia. Ossicular reconstruction was achieved using a SMart 360 nitinol fluoroplastic piston (Gyrus ACMI, Inc.; South-borough, Mass.), and complete posterior crurotomy was performed with a KTP laser. Hearing was assessed with clinical voice testing immediately postoperatively and with pure-tone audiometry at 6 weeks postoperatively. A total of 248 ears (97.6%) demonstrated ABG closure to <10 dB. Bone-conduction thresholds showed an increase in 114 (44.9%), no change 74 (29.1%), and a decrease in 66 (26.0%). There is a slight increase in the risk of stapes mobilization in ears with a small ABG when compared to those with larger ABGs; however, this can be overcome by using a laser-assisted technique in combination with good surgical experience. The benefit in terms of hearing aid avoidance and the restoration of symmetrical hearing is both achievable and significant for the patient.

Objective Stapes surgery for otosclerosis occasionally requires revision due to recurrent or persistent conductive hearing loss (CHL). This study examines outcomes after revision stapes surgery. Study Design Retrospective review. Setting Single tertiary neurotology center. Methods Patients undergoing revision stapes surgery for otosclerosis from 2008 to 2017 were reviewed. Postoperative air-bone gaps (ABGs) were the primary outcome measure. Results During the study period, 150 patients underwent revision stapes surgery. One hundred patients (67%) had gradually progressive recurrent CHL; 16 (11%), sudden recurrent CHL; 13 (9%), persistent CHL; and 21 (14%), no CHL. For 129 patients with CHL, the mean ABG improved from 23.7 to 9.3 dB ( P < .0005). The most common intraoperative findings for these patients were prosthesis displacement with incus necrosis (38%) or without it (43%), normal anatomy with seemingly good prosthesis placement (6%), and abundant scar tissue (6%). Patients with recurrent hearing loss achieved lower mean ABGs than patients with persistent hearing loss (8.8 vs 13.2 dB, P = .02). There were no associations between onset pattern of CHL or intraoperative findings and hearing outcomes ( P > .05). Four patients (2.7%) developed sensorineural hearing loss after revision, defined as an increase in bone conduction pure tone average ≥15 dB, all of whom had previous replacement of a malpositioned prosthesis. Conclusions Revision stapes surgery confers significant improvement in hearing for patients with persistent and recurrent CHL, although patients with persistent CHL after initial surgery see less improvement with revision.

Objective: During the postoperative period, most patients with otosclerosis report vertigo and/or nausea caused by interventions within the inner ear. The aim of this study was to evaluate both early and late vertigo associated with hearing improvement after stapes surgery for otosclerosis. Methods: The analysis included 170 patients admitted to the hospital undergoing their first surgery for otosclerosis. Audiological diagnostics, surgical techniques, and symptoms reported by the patients were all analyzed. Results: A statistical correlation and an unfavorable influence of late, undesired symptoms, such as vertigo, nausea/vomiting, and nystagmus, on final hearing improvement after surgical treatment of otosclerosis were found. Prostheses that were too long or placed too deep within the inner ear space were the most frequent cause of both vertigo and lack of hearing improvement observed after stapedotomy. Conclusions: A significant negative influence on bone conduction thresholds, particularly at 2000 Hz, was associated with vestibular symptoms persisting for 7 days after the surgery. Symptoms of impaired bony labyrinth function after stapedotomy, persisting for more than 1 year, were associated with insufficient reduction of the air–bone gap and worse improvement in bone conduction thresholds at 1000 and 2000 Hz. The cause of both problems was related to a prosthesis that was too long or placed too deep in the inner ear during stapedotomy.

Objective To systematically review the current literature regarding the operative outcomes of stapes surgery for stapes fixation via the endoscopic and microscopic approaches. Data Sources PubMed, Embase, and Web of Science. Review Methods An electronic search was conducted with the keywords “endoscop* or microscop*” and “stapes surgery or stapedectomy or stapedotomy or otosclerosis or stapes fixation.” Studies were included if they compared endoscopy with microscopy for stapes surgery performed for stapes fixation and evaluated hearing outcomes and postoperative complications. Articles focusing on stapes surgery other than for stapes fixation were excluded. Results The database search yielded 1317 studies; 12 remained after dual-investigator screening for quantitative analysis. The mean MINORS score was 18 of 24, indicating a low risk of bias. A meta-analysis demonstrated no statistically significant difference between the groups with regard to operative time, chorda tympani nerve manipulation or sacrifice, or postoperative vertigo. There was a 2.6-dB mean improvement in the change in air-bone gap in favor of endoscopic stapes surgery and a 15.2% increased incidence in postoperative dysgeusia in the microscopic group, but the studies are heterogeneous. Conclusions Endoscopic stapes surgery appears to be a reasonable alternative to microscopic stapes surgery, with similar operative times, complications, and hearing outcomes. Superior visibility with the endoscope was consistently reported in all the studies. Future studies should have standardized methods of reporting visibility, hearing outcomes, and postoperative complications to truly establish if endoscopic stapes surgery is equivalent or superior to microscopic stapes surgery.

Objective: To examine the clinical factors associated with the effectiveness of stapedotomy in improving hearing sensitivity in Taiwanese patients with otosclerosis. Methods: In this retrospective study, we reviewed the medical records of 31 patients (36 ears) with otosclerosis undergoing stapedotomy performed by a single surgeon. Preoperative and postoperative hearing results were analyzed to identify factors associated with hearing outcomes after stapedotomy in the Taiwanese population with clinical otosclerosis. Results: Compared with preoperative pure tone averages (PTAs), stapedotomy significantly improved postoperative air conduction (AC) thresholds ( P < .0001), bone conduction (BC) thresholds ( P = .025), and air-bone gaps (ABGs; P < .0001). Postoperative closure of ABGs less than 10 or 20 dB was achieved in 16 (44.4%) and 33 (91.7%) of 36 surgical ears. Improvement in postoperative AC thresholds and ABGs and the size of preoperative ABGs were significantly correlated (r = .650, P < .001 and r = .745, P < .001, respectively). Gender-stratified analysis indicated a stronger correlation between improvement in postoperative AC thresholds and preoperative ABGs in male patients than in female patients (r = .893, P < .001 and r = .476, P = .014, respectively), and in postoperative and preoperative ABGs (r = .933, P < .001 and r = .626, P < .001, respectively). With the more stringent criteria for surgical success, factors including age (≤50 years), type (conductive, BC ≤25 dB), and degree (PTA ≤55 dB) of preoperative hearing loss led to more favorable outcomes. Conclusions: We reported evidence supporting a potential gender difference on hearing outcomes after stapedotomy in Taiwanese patients with otosclerosis. Age, type, and degree of preoperative hearing loss may affect the surgical success rate.

AbstractObjectivesTo evaluate the surgical techniques, approaches, audiological outcomes and complications of endoscopic stapes surgery.MethodsSystematic searches of the literature were performed in PubMed, Web of Science and Scopus databases, to identify studies of patients who underwent stapes surgery using endoscopic approaches and studies reporting objective post-operative hearing outcomes. The following information was extracted: surgery duration, complications, surgical technique and audiometric results.ResultsFourteen studies were selected for appraisal, which included a total of 282 ears subjected to endoscopic stapes surgery. Endoscopic stapes surgery seems to provide adequate visualisation of the middle-ear structures, thereby allowing less invasive surgery and potentially equivalent audiological outcomes as compared with a traditional microscopic approach. Other advantages of endoscopic stapes surgery include decreased surgery time, a reduced need for drilling, and auditory results comparable to those of microscopic techniques.ConclusionStudies have shown that endoscopic stapes surgery has similar surgical and functional advantages as compared with microscopic surgery.

AbstractBackground:Patients with advanced otosclerosis can present with hearing thresholds eligible for cochlear implantation. This study sought to address whether stapes surgery in this patient group provides a clinically significant audiological benefit.Objectives:To assess pre- and post-operative hearing outcomes of patients with advanced otosclerosis, and to determine what proportion of these patients required further surgery including cochlear implantation.Methods:Between 2002 and 2015, 252 patients underwent primary stapes surgery at our institution. Twenty-eight ears in 25 patients were deemed to have advanced otosclerosis, as defined by pure audiometry thresholds over 80 dB. The patients’ records were analysed to determine audiological improvement following stapes surgery, and assess whether any further surgery was required.Results:The audiological outcome for most patients who underwent primary stapes surgery was good. A minority of patients (7 per cent) required revision surgery. Patients who underwent cochlear implantation after stapes surgery (10 per cent) also demonstrated a good audiological outcome.Conclusion:Stapes surgery is a suitable treatment option for patients with advanced otosclerosis, and should be considered mandatory, before offering cochlear implantation, for those with a demonstrable conductive component to their hearing loss. A small group of patients get little benefit from surgery and subsequently a cochlear implant should be considered.

OBJECTIVE: To assess clinical safety and efficacy of the erbium: yttrium-aluminum-garnet (Er:YAG) laser in the stapes surgery; to define and optimize parameters that render the procedure safe for the inner ear. STUDY DESIGN: Retrospective study. MATERIAL AND METHODS: A microscope-integrated Er: YAG laser stapedotomy was performed on 29 patients and a conventional stapedotomy on 41 patients. An early (within 1 to 3 days after stapes surgery) and late (at least 6 weeks) pure-tone bone-conduction threshold audiogram was obtained. RESULTS: No statistically significant differences were found by Student's t test over all measured frequencies between pre- and postoperative bone-conduction thresholds in each group. There was no statistically significant difference for all frequencies between early (3 days) and late postoperative mean bone-conduction thresholds. CONCLUSIONS: The results of our preliminary clinical study showed that erbium laser poses no risk to inner ear function. However, the lack of standardization obliges further investigation to establish safe clinical parameters of the Er:YAG laser. EBM RATING: B-3
