The objective of the present study was to clarify the features of otological
complications for hyperbaric oxygen therapy (HBOT) and the risk factors for
these complications. We enrolled 1115 patients (776 males and 339 females; age
5-89 years) who underwent HBOT. All otological symptoms experienced during HBOT
sessions were evaluated, and risk factors were analysed using multivariate
logistic regression analysis. Otoscopic findings and interventions for
otological complications were assessed in 58 symptomatic patients who visited
the Otolaryngology Department. Otological symptoms were experienced by 165
(14.8 %) of the 1115 patients. The multivariate logistic regression analysis
identified ages of >60 years and female sex as independent risk factors, whereas
patients with sports injuries were at lower risk than those with other primary
diseases, except for severe infectious disease. Eighty-two patients (49.7 %)
suffered from symptoms at the first HBOT session. The most prevalent symptoms
were otalgia (157/165), followed by ear fullness (13/165), hearing loss (12/165)
and tinnitus (3/165). One patient experienced vertigo and deterioration of the
bone-conduction pure-tone thresholds, suggesting inner ear barotrauma. In 116
ears of the 58 symptomatic patients, abnormal otoscopic findings were recognized
in 58 ears (50.0 %). Twenty-seven of the 58 ears required myringotomy or tube
insertion, and HBOT was stopped in eight ears in four patients. Of the remaining
58 ears with normal otoscopic findings, 51 received no treatment. Physicians
should be aware of both middle and inner ear barotrauma as potential
complications of HBOT.
