Whether the presence of different degree LF caused by middle ear cholesteatoma aggravates neurosensory hearing loss (NSHL) and what is the degree of the hearing loss caused by LF were still under controversial. This study aimed to investigate whether the LF degree is correlative with the age distribution, disease duration and hearing loss degree for cholesteatomatous patients. Methods The files of 143 patients with middle ear cholesteatoma were selected and reviewed in a retrospective study. Seventy-eight patients with LF were divided into three types according to the degree of destruction of labyrinth. Sixty-five patients without LF were randomly chosen for control. Then, we compared the clinical characteristics of patients with or without labyrinthine fistulae caused by middle ear cholesteatoma. Results According to the study, cholesteatomatous patients with LF were older and suffered longer disease duration than those without LF. Hearing loss is severe with high frequencies both in patients with and without LF. Moreover, inner ear impairment is correlative with the degree of destruction in labyrinth, and more severe destruction in labyrinth follow the more severe symptoms correlative with inner ear impairment. Conclusion Surgical intervention should be performed as early as possible for these cholesteatomatous patients.展开更多

There are five general sites of extradural occurrence: the middle ear, external auditory meatus, mastoid, squamous portion and the petrous apex of the temporal bone. CC grows slowly and presents no symptoms at the early stage. Delayed and mis-diagnosis are common with this condition. Case report A 10-year-old boy presented with a 3-month history of hearing loss on right side. There was no history of otorrhea, facial palsy, previous otological procedures or trauma. Otoscopy revealed a bulging posterosuperior quadrant in the otherwise intact right tympanic membrane (Fig.1). Pure tone audiometry showed an average threshold of 51 dB for 500, 1000, 2000 and 4000Hz, with a 40 dB air-bone gap, suggesting a moderate conductive hearing loss(Fig.4). CT scan of the temporal bone showed an isolated soft tissue density lesion in the middle ear(Fig.2).展开更多
