Abstract:
OBJECTIVE:To analyze the imageology features of benign parapharyngeal space (PPS) tumors, and also to summarize our experience in removing PPS benign tumors through transoral approach.
METHOD:A retrospective review was conducted to 48 patients with benign tumors in PPS during a 10-year period. CT were performed in all patients, and only a few required MRI. Transoral approach (33.3%) and transcervical (39.6%) were the most commonly performed surgical procedures followed by the transcervical-transparotid approach (27.1%).
RESULT:CT scan and MRI often provided complementary information to help the surgeons delineate the size, precise location and likely cause of these tumors. After a follow-up of three years, only 2 of 48 patients had disease recurrence. The transoral approach described herein safely allowed for en bloc resection of most benign neoplasms. No significant complications attributed to the approach itself.
CONCLUSION:CT or MRI scan can distinguish prestyloid from poststyloid lesions, and to assess the extension of the tumor as well as its relationship with adjacent structures. The transoral approach safely provides access to some benign PPS tumors with a low rate of complications and recurrence as well as traditional transcervical approaches.
