Objectives:
Surgical management of parotid pleomorphic adenoma ranges from total parotidectomy to extracapsular dissection (ECD). Minimalistic techniques aim to preserve function and minimize the rate of recurrence. This study assesses functional, aesthetic, and disease control outcomes post-ECD through a sole transverse cervical incision for parotid pleomorphic adenoma.
Materials And Methods:
This longitudinal analysis enrolled 36 consecutive patients with pleomorphic adenoma who underwent ECD via a single cervical incision. Complications, satisfaction, salivary function, and tumor recurrence were evaluated. Salivary gland function was assessed using scintigraphy at 6 months post-surgery.
Results:
Tumors occurred in superficial (83%) or deep (17%) parotid inferior parts according to the European Salivary Gland Society level classification. The median tumor size was 2.8 cm (1.8-6.0 cm); the median operation time was 42 min (30-65 min). No tumor spillage or facial nerve injuries occurred. Facial nerve paralysis was only temporary in two (6%) patients, with minimal other complications. Operated parotid gland function matched the unoperated side. No recurrence was found during the median follow-up of 44 months (24-60 months).
Conclusions:
ECD via a single transverse cervical incision is a safe approach for benign parotid tumors, yielding excellent functional and disease control outcomes.
Clinical Relevance:
These findings can provide clinically meaningful minimally invasive recommendations to treat pleomorphic adenoma with minimal complications.
