“…One study reported that 39 patients with acute LFHL recovered almost completely 8 . Another study reported that the hearing of two LFHL patients progressed to profound hearing loss 9 . In treatment of a patient with LFHL, one of the main concerns is the long‐term prognosis because it is not known whether recurrence or progression of hearing loss will occur, as is seen in Ménière's disease.…”

Recently, acute low-tone senseorineural hearing loss (ALHL) has become common, and its good prognosis is known well. On the other hand, several reports have suggested that ALHL is frequently associated with Meniere's disease. We retrospectively examined the clinical course of 357 cases that were diagnosed and treated as ALHL at our hospitals. Forty-four of these cases that showed high-tone hearing loss in association with age-related changes were classified as atypical cases. The clinical futures of 49 "poor prognosis cases", who experienced recurrent hearing loss and/or profound hearing loss, are reported. Eight of the 49 cases who experienced recurrences had progressive hearing loss upto middle or high tones. Seventeen cases complained of vertiginous sensation, and 8 of these cases experienced recurrent attacks of vertigo and were diagnosed as having Meniere's disease. The former seventeen cases accounted for 34.7% of the "poor prognosis cases", and the latter eight accounted for 16.3% of these cases. Our results suggest that the hearing loss is more frequently associated with Meniere's disease in cases who experience recurrent hearing loss. Thus, cases initially diagnosed as ALHL may include some cases of progressive hearing loss and Meniere's disease. Even in cases in which hearing improvement is obtained, careful clinical observation is necessary, especially in older patients with bilateral affliction and atypical presentation. ALHL has been generally considered to have a good prognosis, however our examination revealed a relatively high frequency of recurrences, progressive hearing loss and complication by vertigo. We recommend, based on this evidence, that careful explanation of this disease is necessary at time of initial informed consent.

Acute low-tone sensorineural hearing loss (ALHL) is generally has a relatively good prognosis. We have often found in long-term following-up, however, that ALHL relapses, recurs or develops into Meniere's disease. Diagnostic criteria of the Acute Altitude Deafness Research Group of the Ministry of Health, Labor, and Welfare of Japan, define ALHL as low-tone-disorder sensorineural hearing loss without vertigo in which cochlear symptoms -ear fullness, tinnitus, and deafness- develop suddenly. Over the last five years, we have treated 31 cases of ALHL, in about half of which neurotological examination showed potential peripheral vestibular dysfunction on testing positional nystagmus (a) with closed eyes and (b) in a dark room with open eyes, and by finding laterality in the peripheral labyrinth system on caloric test. These cases show high canal paresis -a maximum slow- phase eye velocity of caloric nystagmus exceeding 60%. These results, taken together, suggest that derangement extends to the peripheral labyrinth system in patients with ALHL.
