![]() 3 These factors have led to the application of HBO as an adjunctive measure for treating conditions resulting from tissue hypoxia, such as clostridial myonecrosis, severe crush injuries with traumatic ischemia, necrotizing fasciitis, chronic osteomyelitis, and nonhealing wounds in diabetic patients and patients with peripheral vascular disease. 2 Also, oxygen tension remains elevated in subcutaneous tissues for several hours after treatment, which further improves the healing process. 1 Elevation of the partial pressure of oxygen in hypoxic tissues to normal or even supranormal levels enhances fibroblast proliferation, supports collagen deposition, stimulates angiogenesis and epithelialization, and enhances leukocyte bactericidal activity. The physiologic basis for the treatment is that the partial pressure of oxygen in the lungs will be increased in direct proportion to an increase in atmospheric pressure. HYPERBARIC oxygen therapy (HBO) has become commonplace in many medical centers as clinical experience continues to document efficacy. Alternative methods of tympanostomy, with emphasis on shorter duration of intubation, should be considered in this patient population. Coexisting illness, such as diabetes mellitus, may contribute to the development of complications in patients undergoing hyperbaric oxygen therapy. Persistent tympanic membrane perforations occurred in 7 patients (16%).Ĭonclusions The rate of complications is higher than reported for placement of tympanostomy tubes in other patient populations. Otorrhea was most common, occurring in 13 patients (29%). Most complications occurred after conclusion of hyperbaric oxygen therapy. Results Seventeen (38%) of 45 patients experienced complications, with most having more than 1. Outcome Measures Charts were reviewed for complications of tube placement, including otorrhea, otalgia, hearing loss, persistent perforations, and tinnitus. Interventions All patients underwent bilateral myringotomy and tube placement. ![]() Patients Forty-five patients referred to the Department of Otolaryngology for inability to tolerate hyperbaric oxygen therapy between January 1, 1990, and December 31, 1995. Objective To document the incidence of complications occurring secondary to placement of tympanostomy tubes in patients undergoing hyperbaric oxygen therapy.
