To investigate common presentations and expected outcomes in patients with traumatically induced otologic dysfunction.
Retrospective case review of patients who underwent otologic surgery for sequelae of otologic trauma over a 28-year period. Patients were stratified into major and minor trauma cohorts. Major trauma was designated as closed head injury with or without temporal bone fracture; lower-energy insults comprised the minor trauma group. Preoperative and postoperative audiograms were obtained and correlated with extent of injury.
Tertiary referral center.
Major trauma accounted for 44.9 percent of all patients. The remaining 55.1 percent suffered minor trauma, of which simple traumatic tympanic membrane perforation was the most common insult (33.6%). Two hundred twenty-seven cases were performed on 214 patients. Pure tone averages improved a significant 20.8 dB to essentially normal levels postoperatively.
Regardless of injury extent, surgical rehabilitation of conductive losses attains excellent hearing results that surpass those historically reported for the chronic ear population.
探讨创伤性耳功能障碍患者的常见表现及预期结果。
对28年间因耳外伤后遗症接受耳科手术的患者进行回顾性病例分析。患者被分为重度创伤组和轻度创伤组。重度创伤定义为伴有或不伴有颞骨骨折的闭合性颅脑损伤；低能量损伤构成轻度创伤组。获取术前和术后听力图，并与损伤程度相关联。
三级转诊中心。
重度创伤占所有患者的44.9%。其余55.1%为轻度创伤，其中单纯外伤性鼓膜穿孔是最常见的损伤类型（33.6%）。对214例患者进行了227例手术。术后纯音平均听阈显著提高了20.8 dB，基本达到正常水平。
无论损伤程度如何，传导性听力损失的手术康复都能取得优异的听力结果，超过了以往报道的慢性耳部疾病患者的听力结果。
