Partial Superficial Parotidectomy via Retroauricular Hairline Incision.

[OBJECTIVES] The purpose of this study was to evaluate the usefulness of retroauricular hair line incision (RAHI) in partial superficial parotidectomy by comparison with modified Blair incision or facelift incision.

[METHODS] Medical records of 73 patients with benign parotid tumor who underwent partial superficial parotidectomy were retrospectively reviewed. Size and location of tumors, operative time, occurrence of facial nerve paralysis and Frey's syndrome, and cosmetic outcomes were compared among RAHI, facelift incision (FLI), modified Blair incision (MBI) groups.

[RESULTS] RAHI group showed better cosmetic results than FLI group or MBI group compared with other type of incisions (P<0.001, P<0.001, respectively). Among the 3 groups, there were no significant differences of operative time and location of tumor (P=0.377), size of tumor (P>0.999), occurrence of temporary or permanent facial nerve paralysis (P=0.745) and Frey's syndrome (P=0.940).

[CONCLUSION] Partial superficial parotidectomy can be done safely by RAHI in most cases of benign parotid tumor. Compared with MBI or FLI, RAHI has better cosmetic outcome with no increase of operative time or postoperative complications.
