頜面部惡性腫瘤有哪些臨床表現?

  頜面部惡性腫瘤有哪些臨床表現?口腔頜面部惡性腫瘤的特點與良性腫瘤有很大區別。
一般生長較快,呈浸潤性生長,癌多發生於老人,肉瘤多見於青壯年。
惡性腫瘤可侵犯、破壞周圍組織,故腫塊界限不清、活動受限。

當惡性腫瘤向周圍浸潤生長時,可以破壞鄰近組織器官而發生功能障礙。
例如,損害面神經可造成面癱;侵犯感覺神經,可引起疼痛或麻木;涉及頜骨時,可引起牙鬆動和病理性骨折;侵犯翼齶凹、咬肌、翼內肌時,可發生開口困難。
隨腫瘤增長,癌細胞可逐漸侵入附近淋巴管和血管中發生轉移。

腫瘤迅速生長破壞而產生的毒性物質,可使病員在腫瘤晚期發生“惡病質”。
病員常因腫瘤迅速生長、轉移、侵及重要臟器及發生惡病質而死亡。
