Cilia and Ear.

OBJECTIVE: To investigate the prevalence of otological complications derived from primary ciliary dyskinesia (PCD) in adulthood. METHODS: Twenty-three patients with diagnosed PCD underwent medical history aimed at recording the presence of ear, nose, and throat manifestations (ENT) and any surgical treatments. The ENT objectivity was annotated, and then patients were subjected to audiometric test, tympanometry, registration of otoacoustic emission, and vestibular evaluation. RESULTS: Otitis media with chronic middle ear effusion (OME) during childhood was reported in 52% of the subjects, no patient had undergone ear surgery, and only 2 patients had an episode of otitis in the last year. Eleven of 23 patients showed normal hearing, 11 had a conductive hearing impairment, and 1 showed a severe sensorineural hearing loss unrelated to the syndrome. The bilateral stapedial reflex was only found in all cases of normoacusia and type A tympanogram, distortion product otoacoustic emissions (DPOAE) were present in 8 patients, and no patient had vestibular alterations. CONCLUSION: Our study confirms a very frequent prevalence of OME in PCD during childhood. Careful monitoring of otological complications of the syndrome is always desirable, also given the high presence in adults of other manifestations in the upper airways, such as chronic rhinosinusitis and nasal polyposis.
