Allows the elimination of infection and inflammation prior to surgical removal. Assessment of the type of surgery is dependant on whether the excess tissue can be removed without impairing the sulcus depth and final denture-bearing area. Hyperplastic tissue arising from the attached mucosa can be excised and left to granulate, as can small areas of tissue limited to the mobile mucosa of the cheeks. Infiltration of local anaesthesia containing vasoconstrictor into the base of the hyperplastic tissue. The excess tissue is held using a traction suture placed at one edge and trimmed using scissors or scalpel.
Care is taken to eradicate the tissue but retain the underlying muscle and periosteum.
A narrow wound of raw mucosa sited in the mobile tissue of the cheek can be undermined and closed. A wider wound of the attached mucosa is left to granulate. The denture can be relined with a periodontal dressing or gutta percha to protect the area and reduce wound contraction. Extensive areas of hyperplastic tissue make loss of depth of the sulcus inevitable after simple excision. To maintain sulcus depth the raw area is repaired using a split skin or, if the area is small, a mucosal graft.
