Hearing loss A study of 224 children following grommet insertion concluded that 25 years after surgical treatment for OME hearing was no different to age- and gender-matched controls. Neither myringotomy alone nor insertion of ventilation tubes resulted in a significant difference in long-term hearing level, compared to a gender-matched normative data set. Where myringosclerosis was present in ears following grommet insertion, there was a small associated loss (4–5 dB) in the high-frequency range. Where pars tensa atrophy occurred after grommet surgery, the long-term change in hearing was limited to an overall loss of 3–4 dB.177

Tympanosclerosis describes the deposition of calcium or bone at sites of previous middle ear inflammation. Usually it affects only the tympanic membrane (myringosclerosis) and is of no consequence. Rarely it may be found to affect the ossicles, often in an ear undergoing exploration for conductive hearing loss, causing fixation of the ossicular heads (treated with partial ossiculoplasty) or around the stapes footplate (usually causing surgery to be abandoned).

Among mixed (n = 5 patients) and conductive hearing loss (n = 1 patient), three were Val122Ile, one Ile107Val, one Arg21Gln and one Gly47Ala. No patient had a history of chronic otitis or otological surgery. Otoscopic evaluation of the tympanic membrane revealed normal findings in 5/6 ears and myringosclerosis in one patient. The mean air-bone gap of mixed hearing loss was 14 ± 7 dB and 11 dB for conductive hearing loss. The tympanometry was normal in all cases. Acoustic reflex was present for all cases.
Hyrtl’s fissures in cochlear implant surgery

On examination, he had bilateral myringosclerosis. Examination of his vestibular system revealed a full range of external ocular movements, smooth pursuit and no nystagmus. Audiograms showed bilateral profound sensorineural hearing loss.
