Title: [abstract] A Descriptive Analysis of Middle Ear barotrauma in Patients Undergoing Hyperbaric Oxygen Therapy
Author: Hunter, SE; Freiberger, JJ; Dear, GdeL; Stolp, BW; Moon, RE
Abstract: BACKGROUND: Otic barotrauma (OB) is common in patients undergoing hyperbaric oxygen therapy (HBO). While there is anecdotal evidence that head and neck disease, advanced age and prior radiation are risk factors for OB, there are no reports in which risk factors have been systematically analyzed. METHODS: Data on a consecutive series of patients treated with HBO in 1999 N=166 were reviewed for risk factors for OB. Factors analyzed were: age, gender, neurological impairment, indication for HBO, prior radiation, head and neck disease, history of ear disease, and current tobacco and/or alcohol use. Patients receiving pre-treatment tubes or myringotomy (N=23) were excluded from the analysis. RESULTS: Twelve of 128 cases had OB. No OB was reported in patients treated for decompression illness, crush injury or acute ischemia. The diagnoses and risk factors for OB are illustrated in the table below. DIAGNOSIS N percentOB VARIABLE ODDS RATIO 95percent CI, Osteoradionecrosis 4 33.3percent Age greater than 55 5.70 1.22, 26.73, Soft tissue radionecrosis 4 33.3percent Male gender 0.13 0.03, 0.58, Necrotizing infection 2 16.7percent, Head/Neck disease 4.22 0.96, 18.53, Skin graft prep 1 8.35percent Current EtOH use 2.15 0.91, 5.08, Osteomyelitis 1 8.35percent NS. DISCUSSION: Based upon analysis of 1999 data, we conclude that age greater than 55 and female gender are predictors of OB in patients treated with HBO. Alcohol use, neurologic impairment, history of ear disease, current tobacco use, prior radiation and the presence of head and neck disease were not significant in this analysis.
