The purpose of this study was to assess the diagnostic and differential value of high-resolution computed tomography in the evaluation of temporal-bone dystrophies. The study group included 55 patients with osseous abnormalities of the temporal bone in general, and the labyrinthine capsule in particular. In 27 patients the CT scan revealed evidence of otodystrophic lesions. The CT findings in patients with otosclerosis (21 patients), osteogenesis imperfecta (two patients), fibrous dysplasia (one patient), Paget's disease (one patient) and osteopetrosis (two patients) are described. The CT scans of 17 patients revealed secondary osseous lesions due to metastasis (five patients), post-inflammatory changes (10 patients) or labyrinthitis ossificans (two patients). Normal variants and congenital mineralization defects were diagnosed in nine patients, Down's syndrome in two. Our results indicate the importance of high-resolution computed tomography as the primary imaging modality in evaluating osseous lesions of the temporal bone and labyrinth.
本研究的目的是评估高分辨率计算机断层扫描在颞骨营养不良评估中的诊断及鉴别价值。研究组共纳入55例颞骨存在骨质异常的患者，尤其是迷路包囊异常。CT扫描显示，27例患者存在耳营养不良性病变。文中描述了耳硬化症（21例）、成骨不全症（2例）、骨纤维发育不良（1例）、佩吉特病（1例）及骨硬化症（2例）患者的CT表现。17例患者的CT扫描显示存在继发于转移瘤（5例）、炎症后改变（10例）或骨化性迷路炎（2例）的骨质病变。9例患者被诊断为正常变异及先天性矿化缺陷，2例患者患有唐氏综合征。我们的研究结果表明，高分辨率计算机断层扫描作为评估颞骨及迷路骨质病变的主要影像学检查方法具有重要意义。
