[The application of modified cosmetic incision and skin adhesive in parotid benign tumor functional surgery].

Objective: To investigate the clinical application value and related technology of modified cosmetic incision and cyanoacrylate octyl ester skin adhesive (Dermabond) in functional surgery of parotid benign tumor. Method: Forty-two cases of clinical cases were collected and randomly divided into groups of A and B. Group A used the approach of modified cosmetic incision,intradermal suture with 6-0 absorbable Vicryl stitches and gluing the skin with Dermabond. Group B used the approach of traditional S shaped incision and continuous suture of skin with 4-0 Prolene stitches.The operative time, postoperative drainage volume, facial nerve function, salivary leakage, Frey syndrome, postoperative numbness, scar and aesthetic satisfaction were compared between the two groups. Result: The operation time, facial nerve function,Frey syndrome, salivary fistula, facial deformity and tumor recurrence in the two groups had no significant difference ( P >0.05); but for postoperative drainage, postoperative numbness, facial appearance satisfaction, scar assessment, Group A was lower than Group B and there was statistical significance difference ( P <0.05). Conclusion: The application of modified cosmetic incision and Dermond is safe and feasible. Its complication is lower than the traditional operation. The scar is smaller and more hidden, and the patient's satisfaction is higher. It doesn't affect the daily social interaction of patients, and achieves the effect of minimally invasive treatment.
