The present study reports the clinical features of middle ear barotrauma in student pilots in the Republic of Korea Air Force.
The authors reviewed medical records of student pilots with barotrauma. The grade of barotrauma was assigned using Teed's classification. This study included nasal symptoms, endoscopic findings of the nasal cavity, and clinical course (duration, recurrence). The relationship between middle ear barotrauma and the nasal airway was also evaluated.
There were 57 cases in 51 pilots included. There were 49 cases (86.0%) that showed unilateral disease and 4 subjects experienced relapse. Two subjects (3.9%) had chronic rhinosinusitis and four subjects (7.8%) had allergic rhinitis. Ear fullness was reported in all cases, while hearing loss and persistent ear pain were reported in 3 cases (5.3%) and 19 cases (33.3%), respectively. Stuffy nose (26 cases, 45.6%) and rhinorrhea (24 cases, 42.1%) were relatively common. Most cases were Grade 0 (23 cases, 40.3%) or Grade III (27 cases, 47.4%) according to Teed's classification. Septal deviation was observed in 12 cases (21.0%), while turbinate hypertrophy was seen in 53 cases (93.0%) and increased nasal discharge in 33 cases (57.9%). The grade of barotrauma varied significantly according to the severity of turbinate hypertrophy and nasal discharge. The mean duration of disease was 6.8 d.
Nasal symptoms and endoscopic findings showed some association with the grade and duration of barotrauma. Most cases resolved within a week; however, barotrauma showed persistence or relapse in some cases.Sohn JH, Cho KR. Middle ear barotrauma in student pilots.

本研究报告了韩国空军学员飞行员中耳气压伤的临床特征。
作者回顾了患有气压伤的学员飞行员的病历。气压伤的分级采用蒂德分类法。本研究包括鼻部症状、鼻腔内镜检查结果以及临床病程（持续时间、复发情况）。还评估了中耳气压伤与鼻气道之间的关系。
纳入51名飞行员共57例病例。其中49例（86.0%）为单侧患病，4例复发。2例（3.9%）患有慢性鼻窦炎，4例（7.8%）患有过敏性鼻炎。所有病例均报告有耳闷胀感，而听力损失和持续性耳痛分别在3例（5.3%）和19例（33.3%）中出现。鼻塞（26例，45.6%）和流涕（24例，42.1%）相对常见。根据蒂德分类法，大多数病例为0级（23例，40.3%）或III级（27例，47.4%）。12例（21.0%）观察到鼻中隔偏曲，53例（93.0%）有鼻甲肥大，33例（57.9%）有鼻分泌物增多。气压伤的分级根据鼻甲肥大和鼻分泌物增多的严重程度有显著差异。疾病的平均持续时间为6.8天。
鼻部症状和内镜检查结果与气压伤的分级和持续时间有一定关联。大多数病例在一周内痊愈；然而，气压伤在某些情况下会持续或复发。
