12 Neck Defects
Posterior Neck
Primary Closure
Indications: Small and medium defects.
Technique: The defect is converted into an ellipse, and the wound margins
undermined in the subcutaneous plane and closed in layers (Fig.12.8a–c, d–g).
Tips: The ellipse can be oriented along a horizontal or vertical axis. A horizontal
ellipse will have to take into account wound tension during neck exion.

O-Z Flap
Indications: Small- and medium-sized defects, circular defects.
Technique: The defect is modied into a circle. Two curvilinear incisions are
made from the opposite poles of the defect. The aps are elevated in the subcutaneous plane and mobilised into the defect. The wounds are closed in layers
(Fig.12.9a–d).
Tips: O-Z aps are rotation transposition aps. The direction of the “Z” can be
adjusted according to the area of maximum skin laxity and in the case of a horizontal
orientation will have to take into account wound tension during neck exion.

Rotation Transposition Flap
Indications: Medium defects.
Technique: The defect is modied into a triangle, and a curvilinear incision is
made from the base of the defect. The ap is raised in the subcutaneous plane and
mobilised into the defect. The wound is closed in layers (Fig.12.10a–c).
Tips: The orientation of the curvilinear incision can be varied according to the
adjacent tissue laxity, but is best placed vertically. A horizontal orientation will have
to take into account wound tension during neck exion. The difference is length and
thickness of the wound margins can be accommodated by differential suturing. Any
dog ears that develop are excised outside the margins of the ap to avoid vascular
compromise.
