No full textOBJECTIVES: We describe the case of a young girl in whom transient deafness occurred when her core body temperature rose. METHODS: The patient was referred for a series of audiological and neurologic evaluations performed over time in both afebrile and febrile states, as well as after a stress test (with a treadmill) in which the body temperature rise simulated the febrile state. RESULTS: The patient was found to have a temporary bilateral hearing loss, but had normal distortion product otoacoustic emissions. Moreover, auditory brain stem responses revealed the absence of neural synchrony when her core body temperature increased. CONCLUSIONS: These results are consistent with a temperature-dependent auditory neuropathy, a rare condition in which patients show normal outer hair cell function and abnormal neural function of the eighth cranial nerve. The symptom is reminiscent of Uhthoff's phenomenon, which is described as transient visual loss and is usually observed in multiple sclerosis. This case of temperature-dependent auditory neuropathy is noteworthy because it sheds light on a disorder of which there have been few reports in the literature. We discuss its similarity to Uhthoff's phenomenon
Malleostapedotomy in tympanosclerosis patients.
No full textObjectives: To present our personal experience of a series of 10 patients suffering from tympanosclerosis with functional blocking of the stapes or footplate, who underwent malleostapedotomy surgery. The criteria for patient selection for this type of operation, and its results and complications, are discussed.Methods: Prospective study.Results: Incus and malleus dysfunction was observed in 70 per cent of cases, either alone or combined with fixation of the stapes. The post-operative hearing results were considered to be satisfactory (i.e. within 20 dB) in 80 per cent of cases. Only one patient had sensorineural hearing loss over 10 dB.Conclusions: Malleostapedotomy has proved its practicability in the treatment of patients with fixed footplate or stapes complicated by ankylosis of the ineudomalleolar joint. This procedure can be considered a further, valid technique within the otologist's surgical armamentarium
