ObjectivesWhile a severe to profound sudden sensorineural hearing loss (SSNHL) may cause serious disability in verbal communication, there have been little studies focusing on this high degree SSNHL. The present study was aimed to investigate the characteristics of hearing recovery in a high degree SSNHL (>70 dB).MethodsThree hundred and two SSNHL patients were enrolled. For a long-term follow-up, 46 patients were evaluated. Hearing level was examined by pure tone audiometry on day 1, week 3, month 3, month 6, and year 1 or after. According to the degree of the initial hearing loss, the patients were divided into 4 groups from 70 to ≥100 dB.ResultsAfter 3 weeks, the recovery rate and mean hearing gain was 61%, 23.85 dB in the 70 dB group, whereas 10%, 6.61 dB in the ≥100 dB group. There was a significant correlation between 3-week recovery and final hearing outcome. However, there was almost no recovery after 3 months.ConclusionAn early recovery can be a prognostic factor for the final recovery in severe to profound SSNHL. Since recovery after 3 months is rare, an early hearing intervention like hearing aid or cochlear implantation should be considered in the high degree SSNHL to restore the patient's verbal communication.
Osteoma of the temporal bone most commonly occurs in the external ear. Osteomas in the middle ear are not common, and only 25 relevant cases (18 papers) have been reported in the English literature. With only 5 cases reported to date, osteoma of the promontory in the middle ear is rare. This study reports a case of asymptomatic osteoma of the promontory in the middle ear mimicking a congenital cholesteatoma in a 4-year-old girl.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
