To achieve excellent hearing results, a firm and stable attachment of the prosthesis to the long process of incus (LPI) is necessary. The present study provides details on the attachment site in two dimensions to choose an appropriate prosthesis and to ensure firm attachment for better surgical outcomes. Objective  To study the diameter of the LPI and its relevance in determining the piston, used in stapes surgery by an in vivo method...

This report aimed to investigate the relationship after successful left-sided stapedotomy and postoperative benign paroxysmal positional vertigo (BPPV) due to vitamin D deficiency. A 56-year-old woman presented with a complaint of progressive hearing loss and tinnitus in the left ear without dizziness. A successful left-sided stapedotomy was performed, confirming the diagnosis of otosclerosis and closing the air-bone gap to less than 10 dB. Seven days after the stapedotomy, the patient reported dizziness, usually when turning to her left side in the bed...

MATERIAL AND METHODS A retrospective analysis was conducted on 56 cases of otosclerosis, comprising 56 ears with a follow-up of over 6 months and complete data. Patients were admitted to the Department of Otology, Huazhong University of Science and Technology Union Shenzhen Hospital from July 2020 to June 2022. SPSS statistical software was used for efficacy analysis...

OBJECTIVE: Recommendations for air travel after stapes surgery, specifically stapes surgery, vary, with no standard recommendation to guide patients and surgeons. According to our search, no previous article has explored the physics of middle ear changes during flight and its effects on poststapedectomy patients in a systematic way. The aim of this study is to bring together 2 arms of expertise, otology, and aviation, to produce an evidence-based recommendation for flight after stapes surgery...

BACKGROUND: Stapedotomy is a common treatment for conductive hearing loss in otosclerosis patients. AIMS/OBJECTIVES: Results of stapedotomy were assessed in terms of hearing improvement and risk of complications. Potential prognostic factors affecting outcomes were identified. MATERIAL AND METHODS: Retrospectively, 93 stapedotomies were evaluated. The primary outcome was hearing improvement based on postoperative ABG ≤10 dB, Belfast rule of thumb, and AC gain ≥20 dB...

BACKGROUND: The stapedial artery is an embryonic artery that transiently supplies the cranial vasculature of the human embryo. Postnatal persistence of the stapedial artery may cause conductive hearing loss and pulsatile tinnitus due to its course through the middle ear. We describe a patient with a persistent stapedial artery (PSA) managed by endovascular coil occlusion prior to stapedotomy. METHODS: A 48-year-old woman presented with left-sided conductive hearing loss and pulsatile tinnitus...

INTRODUCTION: Otosclerosis is the primary cause of conductive hearing loss with normal otoscopy. As the condition worsens, certain patients may develop a sensorineural component. Patients with successful surgeries may still need hearing aids, which creates a dilemma for health professionals as there are insufficient data to make informed decisions. This study investigated the influence of the surgeon's proficiency level, individual patient factors (e.g., age at the time of intervention and survival rates), and surgery costs on the cost-effectiveness of stapes surgery...

BACKGROUND Otosclerosis is a pathology that interferes with the conduction of vibrations to the inner ear, triggering changes in the auditory ossicles and their associated joints due to mechanical overload. This study primarily aims to evaluate these overload-induced modifications in the stapes head resulting from the immobilization of the base of the third auditory ossicle in otosclerosis patients. MATERIAL AND METHODS We conducted a comparative analysis of patients undergoing their first surgery for otosclerosis...

OBJECTIVE: The facial sinus is a recess of the lateral retrotympanum located between the chorda tympani (ChT) and facial nerve (FN). Chronic otitis media with cholesteatoma often spreads from the pars flaccida to the facial sinus (FS). In stapedotomy, if an unfavorable ChT type is encountered, there is a need for removal of bone between the ChT and FN. The aim of the study was to assess FSs in adults and children according to Alicandri-Ciufelli classification, to measure FS width and depth in computed tomography scans, evaluate the correlation between measurements and different types of facial sinuses, and provide a clinical context of these findings...

BACKGROUND: Although many advantages of endoscopic stapes surgery have been reported, there is little objective data on whether it provides better visualization than the microscopic approach. OBJECTIVES: To evaluate and compare audiological results, external auditory canal wall removal area, and adverse event rates between endoscopic and microscopic stapes surgery. MATERIAL AND METHODS: Data from patients who received stapedotomy were collected...

Stapes surgery is generally performed to treat otosclerosis, and there are numerous surgical techniques and prosthesis materials available. Critical evaluation of postoperative hearing outcomes is crucial for identification and further improvement of treatment options. This study is a non-randomized retrospective analysis of hearing threshold levels before and after stapedectomy or stapedotomy in 365 patients during a twenty-year period. The patients were classified into three groups depending on the prosthesis and surgery type: stapedectomy with Schuknecht prosthesis placement and stapedotomy with either Causse or Richard prosthesis...

This is a case of a patient with history of ear surgery who visited ENT outdoor, for continuous vertigo which used to get aggravated with loud noise, associated with hearing loss, persistent sensations of right-sided aural fullness/pressure and otalgia for last 2 years. He had history of tympanoplasty with ossiculoplasty using a TORP. On exploration under local anesthesia there was a displaced prosthesis into inner ear, upon removal of which symptoms and severity subsided exponentially.

UNLABELLED: Endoscopic Ear surgery is evolving day by day and there is need for constant improvement in terms of instrumentation with efficient, quicker, with clear bloodless surgical field and good postoperative outcome and results. The application of Dr Ahila's Endoscopic Ear Surgery Chisel and Mallet are presented. This innovation will provide limited and adequate bone removal in a faster way than drill in endoscopic mastoidectomy and stapedotomy surgeries. Surgical instruments represent a major financial asset to the health care facilities...

PURPOSE: This study aimed to propose a radiological classification of the incudo-stapedial angle by preoperative high-resolution computed tomography (HRCT) images and to highlight its importance for predicting the use of reversal-steps stapedotomy (RSS) rather than the traditional non-reversal technique. METHODS: We included 83 candidates for stapedotomy operation. Two physicians measured the radiological incudo-stapedial joint angle in the preoperative HRCT. According to this measurement, the radiological incudo-stapedial joint was classified into three types: obtuse, right, and acute...

Introduction  Otosclerosis is a common cause of conductive hearing loss in the adult population that is caused by fixation of the stapes footplate. Cochlear otosclerosis may also present with sensorineural or mixed hearing loss. Surgery is the definitive treatment of choice and, during the procedure, sealing of the oval window with autologous tissue graft around the stapes prosthesis has been routinely done to improve hearing outcome and to mitigate postoperative complications. Objective  To evaluate the efficacy of two different types of autologous tissue (vein or fat) grafts as oval window sealing materials in stapedotomy in improving short-term hearing outcomes...

OBJECTIVE: The advantages of laser stapedotomy are less trauma and more precise and minimally invasive techniques; however, the potential risk of overheating from the laser combined with the endoscope tip must be considered. This study aimed to assess the efficacy and safety of diode lasers for endoscopic stapes surgery. METHODS: A retrospective review of 56 patients with otosclerosis who underwent primary endoscopic stapedotomy with a diode laser from 2017 to 2020 was conducted...
