Focus on Epithelialized Palatal Grafts. Part 3: Methods to Enhance Patient Comfort at Palatal Donor Sites

Postoperative discomfort is a documented complication of the epithelialized palatal graft (EPG) procedure, and the expectation of an unpleasant patient experience may cause some practitioners to avoid EPG altogether. However, EPG affords distinct advantages in a variety of clinical situations, and the postoperative discomfort associated with the procedure can be minimized.

Three generally and periodontally healthy patients with gingival recession defects and minimal zones of attached gingiva received mandibular anterior EPG procedures. In all cases, collagen membranes were trimmed to fit the palatal donor sites and sutured in place. Two patients reported minimal donor site discomfort at any time point. One patient with large bilateral donor sites reported moderate palatal discomfort limited to the first postoperative week. All patients reported overall positive treatment experiences.

Placement of a resorbable collagen membrane at large EPG harvest sites appears to limit topical irritation of the wound and may substantially improve patient comfort postoperatively. Combining local and systemic measures to minimize patient discomfort may render EPG procedures very tolerable for patients. Controlled clinical trials comparing patient-centered outcomes following EPG harvest with and without collagen membrane placement appear warranted.
