新疆地区2161例口腔颌面部肿瘤及瘤样病变统计分析

目的 探讨新疆地区口腔颌面部肿瘤及瘤样病变的发病情况和构成特点.方法 对1995年1月至2009年9月在新疆医科大学第一附属医院口腔科门诊活检和口腔颌面外科手术,并经病理确诊的2161例肿瘤及瘤样病变进行回顾性统计分析.结果 良性肿瘤1264例,占58.49%;恶性肿瘤716例,占33.13%;瘤样病变181例,占8.38%.常见良性肿瘤依次为多形性腺瘤、血管瘤、乳头状瘤、Warthin瘤、成釉细胞瘤.恶性肿瘤中以鳞状细胞癌居首,占全部恶性肿瘤的51.96%;涎腺上皮性恶性肿瘤最常见的是腺样囊性癌;牙源性肿瘤中最常见的是成釉细胞瘤.恶性肿瘤的好发部位依次为舌、腮腺、唇、颊.维吾尔族恶性肿瘤构成比为40.27%,汉族为29.18%.结论 新疆地区口腔颌面部肿瘤中良性肿瘤的常见类型、恶性肿瘤的好发部位与国内外报道相似;涎腺恶性肿瘤中腺样囊性癌的构成比远高于其他肿瘤,而牙瘤在牙源性肿瘤中的构成比较低;维吾尔族与同地区汉族比较,其恶性肿瘤的构成比较高.

Analysis of 2161 cases of neoplasm in oral maxillofacial region in Xinjiang

Objective To investigate the incidence and constituent characteristic of neoplasm in oromaxillo-facial region in Xinjiang. Methods A total of 2161 patients with benign or malignant oral-maxillofacial tumors diagnosed in Department of Dentofacial Surgery of the First Affiliated Hospital of Xinjiang Medical College from 1995 to 2009 were analyzed retrospectively.

The most common benign tumors were pleomorphic adenoma, hemangioma, papilloma,adenolymphoma and ameloblastoma. Squamous cell carcinoma constituted the majority of the malignant tumors. The most common malignant tumors of salivary gland were adenoid cystic carcinoma. The most common odontogenic tumors was ameloblastoma. The most common sites of malignant tumors were tongue, lip, parotiod gland and buccal mucosa. Conclusions The common pathological type of oral and maxillofacial benign neoplasm and the most common sites of malignancy in Xinjiang region were similar to those of other places inside and outside the country. Adenoid cystic carcinoma was more common than other salivary originated tumors. There was more malignant tumors in Uygur nationality than in Han living in the same region.
