Abstract:
Sudden postoperative hearing loss is rare, and thought to be caused by a variety of mechanisms. Here we report on a patient with Crouzon syndrome who experienced multiple episodes of postoperative hearing loss, with persistent hearing loss occurring after she received nitrous oxide as part of a general anesthetic. Nitrous oxide is known to cause pressure changes in closed air spaces. Patients with craniofacial syndromes may have acoustic nerve compression from skull base and cartilage anomalies that cause narrowing of the internal acoustic meatus. These anatomic variations may make patients more susceptible to increased middle ear pressure secondary to nitrous oxide, increasing their risk for hearing loss.
