Fig. 5
Intraoperative layout during removal of the middle nostril (a and b), and macroscopic layout of the nose soon after surgery (c) and at 1 month after surgery (d). a The muzzle is incised around the entire circumference of the edge of the middle nostril. b The middle nostril is removed (intact) by whole-circumference exfoliation toward the deepest part of the middle nostril. c The incision line on the muzzle is closed by clamping using four cable ties. d The incised line has healed, although irregularities are observed in a dorsoventral direction on the surface of the muzzle (empty arrow)
