Abstract:
Objective:To analyze the clinical characters and surgical treatment of primary parapharyngeal space (PPS) tumors.
Methods:A total of 23 cases of primary PPS tumors which were treated from November 2011 to December 2017 were included for the retrospective analysis in this study.
Results:Twenty-three cases of patients with primary PPS tumors were analyzed in this study. Surgical approach was as follows: transcervial approach applied in 7 cases, transparotid approach in 4 cases, transoral approach in 2 cases, transmandibular approach in 4 cases, and the combined approaches on 6 cases. Besides, among 7 cases with upper PPS tumor, we applied the surgical navigation system in the surgery of 3 cases. The mean surgery duration of these cases, 3.5 h, was shorter than unused ones, while the mean maximum size (MMS) of tumors, 5.7 cm, was also larger. So far, 23 cases had no recurrence and metastasis. The most frequent histopathological type of all the cases was pleomorphic adenoma (8 cases), followed by Schwannoma (5 cases). With an 8-to-72-months follow up, 23 cases had no recurrence, metastasis or death.
Conclusions:Surgical resection is preferred in the treatment of PPS tumors. In the upper PPS tumor cases, the surgical navigation system could reduce the operative duration significantly and is more suitable for larger tumors.
