Suction cup induced palatal fistula: Surgical closure by palatal rotational flap

Abstract

Construction of complete denture with adequate retention is a complex procedure. Use of suction cup in a maxillary denture is one of the techniques to improve retention. Palatal Suction cup, which provides high retention by inducing negative pressure on the mucosal surface, is not being recommended because of its pathological effect on the palatal tissues leading to palatal perforation. Surgical closure of palatal perforation is challenging, technique sensitive, and it can be achieved by different surgical methods depending on the size and location of the defect. In this case report, we present a patient with palatal perforation due to prolonged use of a denture with a suction cup for over 10 years, which was surgically closed by a palatal rotational flap. The result was good as the defect was successfully closed and the donor site healed uneventfully.

Suction Cup on Denture: A Case Report

“…An adequately polished and glazed denture reduces the poresin the denture reducing the contamination by oral microorganisms. 4 Inflammatory papillary hyperplasia or the epulis fissaratum is to be excised by scalpel, cryosurgery, electrosurgery or laser beam along with antifungal medications. 10…”

“…This occurs as it reduces the blood circulation of underlying tissues leading to hypoxia and necrosis of the underlying bone leading to tissue perforation. 4 The pathological changes are severe with the habit of continuous denture usage for 24 hours a day. But suction cups are used when the diameter is < 1mm and has no risk of irritating the tissues/building up bacteria.…”

Closure of oronasal fistula by palatal rotational flap: case report with two years follow-up

“…Palatal rotational flaps have advantages such as local availability, strong tension force with reliable blood support and good mobility. Similarity with the thickness of the gums, good aesthetics and good accessibility are among the other advantages of this technique 11 . A single-stage method with a high success rate provides sufficient size and length.…”

“…This occurs as it reduces the blood circulation of underlying tissues leading to hypoxia and necrosis of the underlying bone leading to tissue perforation. 2 The pathological changes are severe with the habit of continuous denture usage for 24 hours a day. But suction cups are used when the diameter is less than one millimeter and has no risk of irritating the tissues/building up bacteria.…”
