title: [A comparison between endoscopic-assisted second branchial cleft cyst resection via retroauricular hairline approach and conventional second branchial cleft cyst resection].
abstract: OBJECTIVE
  To assess the feasibility, risks and advantages of endoscope-assisted second branchial cleft cyst (SBCC) resection via the retroauricular hairline approach (RHA) by comparing with conventional trans cervical approach.
  
  
  METHODS
  Using prospective clinical controlled study, in twenty five patients with SBCC, 13 cases underwent endoscope-assisted resection via the RHA, 12 cases underwent conventional transcervical approach resection. Preoperatively, the sizes, locations and adjacency of all lesions were evaluated by ultrasonography, CT or MRI. Pathologic diagnoses of all cases were identified as SBCC using fine needle aspiration biopsy. Two groups were compared at length of incision, operation time, bleeding, incision cosmetic result, complication etc.
  
  
  RESULTS
  All 25 operations were successfully performed. Length of incision and operation time in endoscopic group were significantly longer than that of the transcervical group (P < 0.05). After three months, the mean subjective satisfaction score of incision scar in the endoscopic group was significantly higher than that of transcervical group (P < 0.01). In endoscopic group, 1 cases (7.7%) with temporary numbness of earlobe and 1 case (7.7%) with a darkened color change of the flap margin at the incision angle were found postoperatively. However, they were recovered within 1 month. All the 25 patients were disease free with a follow-up from 18 to 36 months (median follow-up: 26 months).
  
  
  CONCLUSIONS
  Endoscope-assisted SBCC resection via RHA is feasible and safe for the treatment of SBCC. In comparison with the transcervical approach, this method can provide an invisible incision and better cosmetic re suits without significant complications.
