ABSTRACT
<p><b>OBJECTIVE</b>To study the clinical characteristics, diagnosis and surgical managements of the parapharyngeal space tumors.</p><p><b>METHODS</b>A retrospective study of 40 patients with primary parapharyngeal space tumors treated from January 2006 to December 2008 in Chinese PLA General Hospital was performed. Among the 40 patients, there were male 22 patients, female 18 (45%), age ranged from 1 - 77, median 42 years old. CT scan combined with MRI was helpful to diagnose the parapharyngeal space tumor and make surgical plan. The surgical approaches include: trans-oral in 1 patient, trans-cervical approach in 22, transcervical-parotid approach in 8, vertical ramus osteotomy approach in 1, transcervical-partial bone resection in the angle of mandible in 4, transparotid approach in 2, and transcervical in combination with post auricle craniotomy approach in 2.</p><p><b>RESULTS</b>All 40 patients had undergone surgical treatment. Postoperative histopathology showed benign in 28 patients and malignant in 12 patients. The tumors originating from salivary glands were in 15 patients, neurogenic tumors in 12 patients and tumors originating from other tissues were in 13 patients.Among 28 patients with benign tumors, 23 had been cured with one operation, without recurrence during following-up of 13 - 47 months, with a median of 39 months. Among 12 patients with malignant tumors, 6 patients alive (with following-up of 24 - 50 months and a median of 36 months), 3 patients died in half year after operation and 3 patients lost. The post-operative complication included Cerebrospinal fluid leak in one patient, operative field infection in 2 patients, and vagus nerve injury in 3 patients.</p><p><b>CONCLUSIONS</b>Surgery is the first choice for parapharyngeal space tumors. Transcervical approach alone can apply to most tumors and a broader approach is indicated for malignant or large benign tumors. The prognosis is good for the benign lesions, but poor for the malignant tumors.</p>
