ABSTRACT
Background:
In otosclerosis mixed hearing loss is the most frequent symptom and arises when the focus involves the stapes footplate. Surgeons usually prefer to wait a minimum air-bone gap of 25 - 35 dB before surgery.Objectives:
To evaluate the outcome of microdrill stapedotomy for otosclerosis in patients with a preoperative air-bone gap (ABG) <25 dB versus patients with a preoperative gap ≥ 25 dB.Material andmethods:
For this retrospective study, the outcomes and complications after microdrill stapedotomy were compared between adult patients with a preoperative small ABG (n = 127, ABG <25 dB) and those with a large ABG (n = 254, ABG ≥25 dB).Results:
The postoperative ABG was significantly smaller than the preoperative ABG (p < .05) in both groups; there were no differences in complications rates (severe sensorineural hearing loss, footplate fracture or early postoperative vertigo) between the two groups.Conclusions:
Our findings show that microdrill stapedotomy is safe and can be performed even in patients with a preoperative small ABG without increasing the risk of sensorineural hearing loss due to inner ear damage.Palavras-chave
