咽旁肿瘤在临床上比较少见,Workn总结十年的病案仅发现40例。其中良性82％;恶性18％。而主要是涎腺和神经源性肿瘤,未提及脂肪瘤的病例。Rapidis(1982)报告42例口腔脂肪瘤中,也无发生在咽旁区的病例。Toppzada(1973)指出脂肪瘤发生在咽旁区是罕见的。特别是脂肪瘤的直径一般不超过5cm,本例咽旁脂肪瘤非常巨大,除占据左侧咽旁,突入颌下间隙,凸出颌后凹导致颈部肿物。并充满软腭之中,使悬雍垂推至对侧咽侧壁。经手术切除整个瘤体,为15×12×5cm,重350g。实属一例罕见的咽旁
Parapharyngeal tumors are relatively rare in clinical practice. Workn concluded that only 10 cases were found in a 10-year history. Of these, 82% are benign and 18% are malignant. The main cause is parotid gland and neurogenic tumor. No case of lipoma has been mentioned. Rapidis (1982) reported that 42 cases of oral lipomas did not occur in the parapharyngeal area. Toppzada (1973) pointed out that lipomas are rare in the parapharyngeal area. In particular, the diameter of lipomas generally does not exceed 5 cm. In this case, parapharyngeal lipomas are very large. Except for occupying the side of the left side of the pharynx and protruding into the submandibular space, the posterior cheek of the jaw causes neck masses. Filled with soft palate, the uvula is pushed down to the side wall of the contralateral pharyngeal. The entire tumor was surgically removed and was 15 x 12 x 5 cm and weighed 350 g. It is a rare case of pharynx
