Value of double mucoperiosteal flaps to prevent restenosis in Draf IIb/III: first clinical report

Abstract

Exposed drilled bone in Draf IIb and III procedures promotes restenosis by inducing osteitis and neo-osteogenesis.

This reaction can be avoided by covering bone with local mucoperiosteal flap that optimize the healing process

In a series of 16 patients, a septoturbinal flap (STF) and lateral based nasoseptal flap (LNSF) are harvested to cover the posterior and anterior edge of the frontal cavity, respectively.

These flaps do not overlap and can be harvested from the same side.

Clinical feasibility of double mucoperiosteal flaps in Draf IIb and III was demonstrated with promising results in terms of frontal cavity restenosis prevention (93.75% success rate). A favorable healing process was noted with minimal crusting during the postoperative period.
