Analyses of chronic otitis media with intact tympanic membrane concurrent with intracranial complication / 中华耳鼻咽喉头颈外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical and imaging characteristics of chronic otitis media with intact tympanic membrane.</p><p><b>METHOD</b>Ten patients were retrospective studied in the department of otorhinolaryngology of Guangdong general hospital from December 2006 to January 2015. The clinical characteristics of their manifestations, audiology and imaging examinations were analyzed.</p><p><b>RESULTS</b>All the cases could be divided into two groups the intracranial complication group who was primarily diagnosed as intracranial complications, and the hearing loss group who primarily complained of hearing loss. Five cases belonged to the first group, which include 1 cerebellar abscess, 3 meningitis and 1 meningoencephalitis, 2 of them were profound hearing loss, 2 were mixed hearing loss, and 1 was normal hearing. The other 5 cases belonged to the hearing loss group, 3 were mixed deafness, 2 were conductive deafness. All the case showed positive high-resolution computed tomography (HRCT) features. In the first group, four cases showed the soft tissue shadow in tympanic antrum/superior tympanic pouch and 1 case showed a wide damage of skull base, in addition to intracranial complications. In the second group, five cases showed soft tissue imaging in tympanic antrum/superior tympanic pouch. Pathology showed that 2 cases were cholesterol granuloma(one was in the first group and the other was in the second group), 4 were intracranial inflammatory(the first group) and 4 were cholesteatoma(the seond group).</p><p><b>CONCLUSIONS</b>In chronic otitis media with intact tympanic membrane, intracranial complications may be the primarily diagnosis, which should be paid much attention by multidisciplinary team. HRCT and audiology were valuable for early diagnosis.</p>
