Although they may be cosmetically desirable in certain dog breeds, excessive periocular, facial, and forehead skin and skin folds may be associated with significant ocular surface damage, which can lead to varying degrees of vision loss and discomfort. Surgical intervention is frequently indicated in affected patients, and multiple surgical procedures have been described.1-3 The least invasive procedure that also preserves desirable breed-related cosmetic features, as with the brow suspension technique described in this retrospective study, should ideally be used.
This modification of a previously described procedure4 uses sutures to create a sling deep to the frontalis muscle that, when tightened, pulls the rostral-most forehead skin caudally, alleviating downward force on the eyelids (ie, pseudoptosis) and creating a forehead and brow “lift.” The sling is created by anchoring monofilament, nonabsorbable sutures to the frontal bone periosteum with 3 parallel skin incisions. The most rostral suture should be made over the dorsal orbital rim, with the next 2 sutures made caudal to each of the preceding sutures. Multiple slings can be placed above each eye depending on the degree of pseudoptosis; however, it is important to note that additional procedures to correct entropion may be necessary, as the sling does not directly impact the position of the eyelid margin relative to the globe. In the original procedure,4 the skin incisions were more rostrally located, with the first incision located 2 mm caudal to the upper eyelid margin. The sling was also created using a polyester mesh implant rather than sutures alone.
