ABSTRACT
O to Z closure may be used when closure under tension or deviation of tissues will have adverse consequences (e.g. around the nares or eyes) (94b, 3). With this technique, curvilinear incisions are made in opposite directions on opposite sides of the circle. The resulting flaps are undermined and brought together to result in a Z-shaped closure. ii. The skin incision may be extended through the ‘dog ear’ and two triangles of affected skin removed (94b, 4), incision along the base of one ‘dog ear’ and extension of the incision through the ‘dog ear’ (removal of the resulting skin triangle results in a curved end to the incision) (94b, 5), extension of a fusiform incision to include the affected skin with closure of the defect routinely (94b, 6).
