Tearing Mucosal Flap

Tearing Mucosal Flap

The most common soft tissue injury is the tearing pf the mucosal flap during surgical extraction of a tooth. This is usually-the result of an inadequately sized envelope flap, which is retracted beyond the tissue’s ability to stretch
(Fig. 11-1). This results in a tearing, usually at one end of the incision.  Prevention of this complication is twofold: (1) create adequately sized flaps to prevent excess tension. On the flap, and (2, use small amounts of retraction for,.ce on the flap. If tear does occur in the flap, the flap should
be carefully re positioned once the surgery is complete. In most patients, careful suturing of the tear results in adequate but delayed healing. If the tear is especially jagged, the surgeon may consider excising the edges of the join flap to create a smooth flap margin for closure. This latter step should be performed with caution, because excision of excessive amounts of tissue leads to closure of the wound under tension and probable wound dissidence. If the area’ of surgery is near the apex of a tooth, an increased incidence of envelope-flap tearing exists as a result of excessive retractional forces. In this situation a release incision to create a three-cornered flap should be used to gain access to the bone
