Modified buried vertical mattress suture technique for excisional suturing of benign parotid tumors: A retrospective study.

AIM

The purpose of this retrospective patient chart review was to analyze the clinical data of 52 patients with benign parotid tumors who underwent modified buried vertical mattress sutures and to assess the postoperative complication rate and patient scarring.

METHODS

A total of 52 patients with benign parotid tumors underwent total parotidectomy and modified buried vertical mattress suture. Variables included general characteristics (age, gender, tumor diameter, and pathologic type), surgical indicators (suture time, wound healing time, operative time, hospital stay, bleeding volume, and drainage volume), complication rates, and Sunnybrook facial neurological function score, visual scar scale (VSS) score and patient and observer scar assessment scale (POSAS) score.

RESULTS

Most tumors were less than 3 cm in diameter, with pleomorphic adenomas being the most common. Suture time was 14.83 ± 1.61 min, operative time was 58.90 ± 15.76 min and hospital stay were 5.12 ± 0.96 days. Postoperatively, salivary fistulae developed in one patient, Frey's syndrome in two patients, temporary facial paralysis in six patients and temporary numbness in the incision area in six patients. At 6 months postoperatively, 86.5% of patients had a Sunnybrook score of more than 80, and VSS scores and POSAS scores were between one and two.

CONCLUSION

The postoperative complication rate was 30.8%, and the scarring in the facial incision area was mild and close to normal skin at 3 years postoperatively.
