Introduction: The appropriate therapy of benign parotid tumours, esp. pleomorphic adenomas (PA), is still controversely discussed. Superficial and total parotidectomy are often regarded as the preferebale procedures. The recurrence rate of PA after extracapsular dissection (ED) is part of the controversy.
Methods: We performed a retrospective analysis concerning all patients who were primarily operated because of a PA between 2000 and 2005; in cases of ED as the surgical technique, a clinical and sonographical follow-up examination was performed.
Results: 560 patients were treated because of a parotid benignoma, of which 204 were primarily diagnosed PA. In 67 patients with PA (32.8%) an ED was performed. No recurrence of PA was observed after a mean follow-up of 6.38 years (4.05–9.52 years).
Conclusion: ED of benign parotid tumours is a less invasive technique compared to superficial and total parotidectomies; thus the rate of postoperative complications, facial nerve paresis in first place, is significantly lower. Our data support the results of other groups that ED of PA does not show an increased recurrence rate compared to the parotidectomies. Studies with a longer follow-up period and a comparison between the different surgical techniques have to follow.
