Purpose
Warthin tumors (WT) are the second most common benign parotid gland neoplasms. They can occur as synchronous or metachronous lesions in 6–10% of cases. This study aims to compare the complication rate in 224 patients who underwent extracapsular dissection (ECD) or superficial parotidectomy (SP) for the treatment of a WT.
Methods
This retrospective study was conducted at the Department of Maxillo-Facial Surgery at the University of Naples “Federico II” from February 2002 to December 2018 on a group of patients who underwent surgical treatment for WT. The type of surgical technique was chosen based on Quer’s classification. The complications evaluated were facial nerve palsy, hematoma, Frey’s syndrome, and bleeding.
Results
A total of 224 patients treated from 2002 to 2018 for Warthin tumor were included in the study. Two hundred elven had solitary tumors (94.1%) and 13 had multicentric lesions (5.8%), of which 9 cases presented synchronous lesions and 4 cases presented metachronous lesions. Extracapsular dissection (ECD) was performed in 130 patients (58.3% of cases) and superficial parotidectomy (SP) in the other 94 (41.7% of cases).
Conclusions
We consider both surgical techniques as valid. In our opinion, it is essential to study each case based on Quer’s Classification to obtain the best surgical outcome. Based on a lower observed rate of complications such as facial nerve palsy, Frey’s syndrome, and bleeding, ECD seems to be the best option for the surgical treatment of Quer Class I lesions.
