Osteomas are benign bone tumors most commonly found in the external auditory canal, often mistaken for exostoses. While typically asymptomatic, larger osteomas can cause hearing loss, tinnitus, or canal obstruction.
A 20-year-old Syrian male presented with progressive right-sided hearing loss and difficulty inserting ear-cleaning tools, persisting since age 13 years. Previous conservative management with canal dilation was unsuccessful. Examination revealed partial occlusion of the external auditory canal, and otoscopy was not possible owing to the stenosis. Axial and three-dimensional computed tomography scans identified a bony bridge connecting the mastoid and zygomatic processes, obstructing the canal. Audiometry confirmed conductive hearing loss (40-50 dB air-bone gap). The patient underwent postauricular excision, bony drilling, and canal reconstruction. Postoperatively, the air-bone gap resolved, and canal patency was restored. Histopathology confirmed a benign osteoma.
Despite being benign, this condition warrants more research to address knowledge gaps and improve diagnosis, especially in underserved areas. Better understanding and awareness could significantly enhance patient management and quality of life.
骨瘤是最常见于外耳道的良性骨肿瘤，常被误认为是外生骨疣。虽然通常无症状，但较大的骨瘤可导致听力损失、耳鸣或耳道阻塞。
一名20岁的叙利亚男性自13岁起出现进行性右侧听力损失，且难以插入耳部清洁工具。先前采用耳道扩张的保守治疗未成功。检查发现外耳道部分闭塞，由于狭窄无法进行耳镜检查。轴向和三维计算机断层扫描显示有一个骨桥连接乳突和颧突，阻塞了耳道。听力测定证实为传导性听力损失（气骨导差40 - 50分贝）。患者接受了耳后切除、骨钻孔和耳道重建手术。术后，气骨导差消失，耳道通畅得以恢复。组织病理学证实为良性骨瘤。
尽管这种情况是良性的，但仍需要更多研究来填补知识空白并改善诊断，尤其是在医疗服务不足的地区。更好的理解和认识可显著提高患者管理水平和生活质量。
