INNERVATED REVERSE DIGITAL ARTERY FLAP THROUGH BILATERAL NEURORRHAPHYFOR PULP DEFECTS

To provide sensation to the reverse digital artery (RDA) flap, both th e dorsal branch from the proper digital nerve and the superficial sens ory branch from the corresponding radial or ulnar nerve are sectioned at their proximal ends and included with the RDA flap. These are then anastomosed with the distal ends of both radial and ulnar digital nerv es at the recipient wound. Three cases of pulp defects reconstructed b y this technique achieved very favourable functional and cosmetic resu lts. The RDA flap, innervated through bilateral neurorrhaphy, seems to be an excellent option for one-stage reconstruction of major pulp def ects.
