目的:通过张口受限6 例误诊临床回顾性分析, 扩大张口受限的诊断思路。方法: 采集6例1987年4 月至1998年4月已被病理证实的临床资料进行回顾性分析。结果: 6例中确诊为腮腺腺癌2例, 被误诊为破伤风和腮腺混合瘤。颊部鳞状细胞癌1例, 被误诊为颌上淋巴结炎。颞下窝横纹肌胚胎肉瘤1 例, 被误诊为颌间疤痕挛缩。腮腺嚼肌区间隙感染1 例,被误诊为咬肌部横纹肌肉瘤。上颌窦鳞状细胞癌1 例, 被误诊为颞下颌关节紊乱综合证。结论: 利用多谱勒定位, 细针(0.6m m ) 抽吸活检, 提高诊断准确率, 是值得推广的一种早期诊断方法。
OBJECTIVE: To expand the diagnostic concept of restricted mouth opening in 6 cases of misdiagnosis and clinical retrospective analysis. Methods: Six cases of clinical data confirmed by pathology from April 1987 to April 1998 were retrospectively analyzed. Results: Two cases of adenocarcinoma of the parotid gland were diagnosed in 6 cases and were misdiagnosed as mixed tetanus and parotid gland tumors. One case of cheek squamous cell carcinoma was misdiagnosed as supracondylar lymphadenitis. One case of striated muscle sarcoma in the infratemporal fossa was misdiagnosed as jaw scar contracture. One case of gap infection in the chewing muscle region of the salivary gland was misdiagnosed as rhabdomyosarcoma of the masseter muscle. One case of maxillary sinus squamous cell carcinoma was misdiagnosed as a syndrome of temporomandibular joint disorder. Conclusion: Using Doppler localization and fine needle (0.6m m) aspiration biopsy to improve the diagnostic accuracy is an early diagnosis method worthy of promotion.
