Background:
This study was carried out to evaluate tumor recurrence following extracapsular dissection of pleomorphic adenomas of the parotid gland.
Methods:
We conducted a retrospective evaluation and clinical follow-up of the patients who underwent extracapsular dissection of a pleomorphic adenoma as primary surgery in the otolaryngologic department of the Erlangen University Clinics during the period from 2000 to 2005.
Results:
In all, 601 surgical interventions on benign parotid tumors were carried out from 2000 to 2005, 219 of which were primary operations for removal of a pleomorphic adenoma. In 76 patients (34.7%), extracapsular dissection of a primary pleomorphic adenoma was carried out. Tumor recurrence has not been observed in any of these patients to date after an average monitoring period of 7.38 years (range, 5.05-10.52 years).
Conclusions:
Extracapsular dissection is a conservative and safe surgical procedure for extirpation of pleomorphic adenomas that should be firmly established in the repertoire of parotid gland surgery.
