Sudden onset hearing loss following intra-abdominal surgery: an unusual association.

We describe the case of a 12-year-old boy who reported unilateral hearing loss following laparoscopic appendicectomy for acute appendicitis under general anaesthesia. He was otherwise fit and well with no previous otological history. Formal audiological assessment by pure tone audiogram demonstrated a unilateral high-frequency sensorineural hearing loss (SNHL).In addition to describing his clinical course, a literature review of SNHL following non-otological surgery was performed. We recommend an awareness of this phenomenon, necessitating its prompt recognition, early audiological assessment and management as per sudden onset SNHL guidelines. © BMJ Publishing Group Limited 2020.
