Periodic observation with imaging is an acceptable option for patients small vestibular schwannomas (VSs). The objective of this study was to evaluate the outcome conservative management intracanalicular VSs (ICVSs).We reviewed 31 who were followed up more than 1 year among diagnosed as having VS limited internal auditory canal. median follow-up period months (range, 12-84 mo). We analyzed patients' clinical features, courses, and audiologic changes.The most frequent initial presenting...
Objectives A sphenoid sinus fungal ball is a rare disease that can cause visual disturbances. Most afflicted patients remain in an indolent state. However, once the disturbance has occurred, recovery rate very low. The purpose of this study was to overview clinical characteristics with and ascertain factors possibly related occurrence disturbance. Methods We retrospectively reviewed medical records all who underwent endoscopic surgery for at our hospital. enrolled 47 study. Results Old age...
This study was conducted to investigate the electroacoustic characteristics of personal sound amplification products (PSAPs), identify whether PSAPs provide adequate gain and output for three common hearing loss (HL) configurations, compare benefits a representative PSAP (RPSAP) conventional aid (HA) clinical outcomes as pilot study.The comprised phases: analysis, simulated real-ear measurements (REMs), experiments. Electroacoustic analysis REMs were performed basic (BeethoSOL, EarJJang,...
Abstract Intravenous gadolinium-enhanced inner-ear magnetic resonance imaging (IV-Gd MRI) has been used to visualize endolymphatic hydrops (EH) in clinical diagnosis of Ménière’s disease (MD). However, lack histological validation led several concerns regarding how best interpret the resulting images. Here, we compared hydropic changes temporal bone specimens with results IV-Gd MRI patients MD. Histopathologic images bones from 37 MD and 10 healthy controls were collected National Temporal...
Objective: To analyze the factors associated with benefits of concurrent administration intratympanic steroid injection (ITSI) and oral steroids in patients acute acoustic trauma (AAT) incurred during military training. Study Design: Retrospective analysis. Patients: Nineteen eligible under criteria established concerning treatment for AAT were retrospectively reviewed this study. Interventions: ITSI treatments administered simultaneously alongside prednisolone. Main Outcome Measures:...
Objectives. Patients’ clinical presentation is critical for identifying suspected perilymphatic fistula (PLF). The involvement of third-window lesions in the pathomechanism PLF has been hypothesized. This study investigated features and relationship effect with PLF. Methods. Sixty patients underwent surgical exploration oval round windows were reinforced. Clinical including demographics, pure-tone audiometry (PTA), videonystagmography evaluated preoperatively 1 month postoperatively....
Background and Objectives: Wireless streaming technology (WT), designed to transmit sounds directly from a mobile phone hearing aids, was developed enhance the signal-to-noise ratio. However, advantages of WT during use specific demographic that can fully benefit this has not been thoroughly evaluated. We aimed investigate benefits identify predictive factors associated with bilateral wireless among aid users.Subjects Methods: Eighteen adults symmetrical, loss participated in study. To...

During the treatment process for benign paroxysmal positional vertigo (BPPV) using canalith repositioning procedure, otolith can inadvertently enter semicircular canal instead of utricle. Canal conversion refers to situation where enters a different canal, while reentry occurs when returns same canal. The occurrence complicate accurate diagnosis and BPPV, potentially leading misdiagnosis unsuccessful results in procedure. In this review, we aim summarize incidence, clinical features,...
Abstract Ménière’s disease (MD) is characterized by episodic vertigo, tinnitus, and hearing loss. Endolymphatic hydrops (EH) a histologic marker of MD. We aimed to investigate whether symptom improvement following medical treatment would decrease the ratio calculated intravenous gadolinium-enhanced inner-ear magnetic resonance imaging (IV Gd MRI) in cochlea vestibule. This prospective study included 9 patients diagnosed with unilateral definite All were treated medically. Patients underwent...
