Use of a Cervicofacial Flap in Closing Large Defects Following Wide Local Excision of Complicated Preauricular Lesions.

Purpose: To describe innovative surgical technique for closure of large defect following complicated preauricular cyst excision secondary to prior failed excision attempts, infections, and drainage procedures. Preauricular cysts must be widely excised including any fistulous tracts in order to reduce recurrence rates; however, the resultant large local excision poses cosmetic challenges. Methods: Retrospective chart review of 3 patient cases who underwent excision of recurrent preauricular lesions involving cervical parotid flap closure. All three cases demonstrate complicated preauricular congenital cysts which were infected and had prior drainage, excision attempts, or sclerotherapy. A cervicoparotid flap was used to close all defects cosmetically with no facial nerve weakness and without distortion to the oral commissure or lateral canthus. Results/conclusions: There is a high recurrence rate seen with wide local congenital cyst excisions that have been previously excised, infected, and drained; as well as, cosmetically unfavorable outcomes utilizing traditional repair. Utilizing our closure technique which involves reconstructive local regional flap with cervicoparotid approach our 3 patients have had no reoccurance of cyst or infection. Our approach also maximizes cosmetic outcomes, with reduced scar visibility. Pre and postoperative photos will be shown. [ABSTRACT FROM AUTHOR]
