A rare case of idiopathic bilateral ossification of the auricular cartilage and cartilage of the external ear canal is reported. The hardening and thickening of the external ear canals with subsequent narrowing and impaired exposure resulted in symptomatic hearing loss because of the recurrent impediment of inspissated cerumen, the removal of which finally became impossible. Surgical resection of the cartilage external ear canal and tragus was indicated to provide a more permanent treatment of conductive hearing loss. Histological examination revealed complete replacement of the fibroelastic cartilage by normal bone structures showing Haversian canals and bone marrow. The present case report is unique because of the involvement of both the auricles and external ear canals, the symptomatic hearing loss and the surgical treatment to relieve symptoms.
报告了一例罕见的特发性双侧耳郭软骨和外耳道软骨骨化病例。外耳道的硬化和增厚，随后变窄以及暴露受限，由于反复出现的耵聍浓缩阻塞，导致了症状性听力损失，最终无法清除耵聍。手术切除外耳道软骨和耳屏以更持久地治疗传导性听力损失。组织学检查显示纤维弹性软骨被显示哈弗斯管和骨髓的正常骨结构完全替代。本病例报告具有独特性，因为双侧耳郭和外耳道均受累、出现症状性听力损失以及采用手术治疗来缓解症状。
