POSITIONING AND PREPARATION
The mare is restrained standing in a stock or
backed into a stall doorway. The tail is held out of
the way by an assistant or wrapped and tied
forward. Following aseptic preparation of the per-
ineal region, local anesthetic (15 to 20 mL using a
22-gauge needle) is infiltrated along the vulvar ~\
labial mucocutaneous margin (Figure 39-1). \1 '

Excessive local anesthetic infiltration should be
avoided to prevent distortion of the mucocuta- ~

PROCEDURE
Beginning at the level of the ischiatic tuber and
extending to the dorsal commissure, a thin band
of mucosa approximately 3 to 5 mm wide is
excised from each side of the vulva along the 'o/.t.12-t:.~t --
mucocutaneous margin' (Figure 39-2). The Figure 39-1 Infiltration of local anesthetic along the
exact length of tissue removed depends on the vulvar mucocutaneous margin,
