title: Endoscope-assisted extracapsular dissection of benign parotid tumors through a single cephaloauricular furrow incision versus a conventional approach.
abstract: A few modified approaches have been reported for performing endoscope-assisted dissections of benign parotid tumors, but none that use incisions totally hidden in a natural furrow. This study evaluated the feasibility of performing endoscope-assisted extracapsular dissections of benign parotid tumors using a single cephaloauricular furrow incision.
  
  
  
  Forty-six patients with benign parotid superficial lobe tumors were randomly divided into two groups: an endoscope-assisted (21 patients) group or a conventional (25 patients) surgery group. Perioperative and postoperative outcomes of the patients were evaluated, including the maximum diameter of the tumors, length of the incision, operating time, estimated blood loss during the operation, amount and duration of drainage, satisfaction scores based on the cosmetic results, perioperative complications, and follow-up information.
  
  
  
  The diameters of the tumors were comparable between the groups, and all operations were successfully performed as planned. The mean length of the incision in the endoscope-assisted group (3.6 ± 0.5 cm) was significantly shorter than that in the conventional group (9.1 ± 1.9). Meanwhile, the intraoperative blood loss, amount of drainage, perioperative complications, and cosmetic outcomes were all improved in the endoscope-assisted group. No tumor recurrence was found during 11-40 months of follow-up.
  
  
  
  Cephaloauricular furrow incisions were totally and naturally hidden in this procedure. Endoscope-assisted extracapsular dissections of benign parotid tumors via a small cephaloauricular furrow incision were found to be feasible and reliable, providing a minimally invasive approach and a satisfactory appearance.
