We investigated the signs and symptoms of middle ear barotrauma in 67 patients with hyperbaric oxygenation treatment as well as the influence of predisposing factors. Ear damage was classified into 5 grades on the basis of objective findings at otoscopic examination. The incidence of middle ear barotrauma assessed by objective criteria was 68.7%, and showed little variation with age or primary disease. On the other hand, the incidence assessed by subjective symptoms was lower than the objectively-based incidence in aged patients, those with severe neurological diseases, and those who had difficulties speaking. Patients with a trauma grade of 2 or more complained of severe symptoms and were appropriate candidates for treatment. It is considered that otoscopic examination should be performed in patients who undergo hyperbaric oxygenation treatment and that prior management of nasal and paranasal diseases is beneficial in the prevention and treatment of middle ear barotrauma.
我们调查了67例接受高压氧治疗患者的中耳气压伤的体征和症状以及诱发因素的影响。根据耳镜检查的客观结果，将耳部损伤分为5级。根据客观标准评估的中耳气压伤发生率为68.7%，且与年龄或原发疾病的变化不大。另一方面，在老年患者、患有严重神经疾病的患者以及有语言障碍的患者中，根据主观症状评估的发生率低于基于客观标准的发生率。创伤等级为2级或更高的患者抱怨有严重症状，是合适的治疗对象。认为对接受高压氧治疗的患者应进行耳镜检查，并且对鼻和鼻旁疾病的预先处理有助于预防和治疗中耳气压伤。
