Use of a porcine dermal collagen graft (Permacol) in parotid surgery

Abstract 

Our aim was to present the results of the use of porcine dermal collagen graft (Permacol) in the prevention of Frey’s syndrome and face-contouring aesthetic deformities after operations on the parotid. We treated 19 patients with parotid tumours. After resection, a Permacol sheet was applied to the perimeter of the tissue deficit so that it was fully covered, and was sutured firmly. This technique produced satisfactory aesthetic results with good facial contouring in all patients. It also protected the exposed parotid nerve plexus, and none of the patients developed Frey’s syndrome. Permacol produced good results in both postoperative facial contouring and prevention of Frey’s syndrome.
