Benign osteoblastoma is an uncommon primary tumor of the bone. Any area of the skeleton may be affected by this tumor, but its occurrence in the temporal bone and middle ear is extremely rare. Clinical symptoms are nonspecific, even in the middle ear, and the diagnosis is often difficult in spite a complete physical and radiological examination. A biopsy is usually necessary for definitive diagnosis. Because of its potential for recurrence, local invasion, and, rarely, malignant transformation, a complete surgical excision remains the treatment of choice for osteoblastoma. We report a case of benign osteoblastoma involving the temporal bone and the middle ear and a review of the literature.
骨母细胞瘤是一种罕见的原发性骨肿瘤。骨骼的任何部位都可能受此肿瘤影响，但其发生于颞骨和中耳极为罕见。临床症状不具特异性，即使在中耳也是如此，尽管进行了全面的体格检查和影像学检查，诊断往往仍很困难。通常需要进行活检以明确诊断。由于骨母细胞瘤有复发、局部侵袭的可能，且极少发生恶变，因此完整的手术切除仍是骨母细胞瘤的首选治疗方法。我们报告一例累及颞骨和中耳的骨母细胞瘤病例并对文献进行综述。
