Lateral anal sphincterotomy - the internal sphincter is divided away from the fissure itself - usually either in the right or the left lateral position.
Anal advancement flap - this operation consists of excision of the edges of the fissure and mobilization of a square, full thickness anal skin flap so that this can be slid forward over the fissure and sutured in place.
