Abstract
Excessive facial skin folds is observed in several breeds of dogs and the weight exerted on the eyelids accents or promotes entropion, trichiasis and ptosis. Thus, this study reported a case of the 8-months-old male Shar-pei weighting 21.5kg was presented with an obstructed visual axis, eye discharge, fetid odor in facial folds around the jaw and the neck. It was indicated the surgical resection of the folds and correction of the upper and lower entropion. In this case, the association of Hotz-Celsus technique with rhytidectomy shaped in semiarchs, using the anchoring points with the modified walking suture, was effective in correcting the entropion and unblocking the visual axis with minimal scarring and preservation of the breed standard in 12 months follow up after surgery.
Highlights
The Shar-pei dog is characterized by the presence of cutaneous wrinkles on the skull, especially in the frontal, maxillary, lacrimal and zygomatic bone regions, which, together with the racial predisposition to entropion, deserve attention (VIANA et al, 2006; GELATT; GELATT, 2011), since the choice of a surgical technique capable of correcting the various changes at the same time represents a challenge in the breed (STUHR et al, 1997)
The weight of the skin folds on the head, especially on the upper eyelids, forcing them down, sometimes makes it impossible to correct the entropion by the technique of Hotz-Celsus alone, making it necessary a combination of techniques (STUHR et al, 1997; WILLIS et al, 1999; GELATT; GELATT, 2011), as well as the resection of the excess of facial folds, called rhytidectomy, term derived from the Greek Rhytis = wrinkles and ektomé = excision, known as facelift (STUHR et al, 1997; MCCALLUM; WELSER, 2004; STEINMETZ, 2015)
Despite the description of techniques for rhytidectomy in dogs, such as the elliptical rhytidectomy in the midline of the craniocaudal head described by Bedford (1990); the stellate technique described by Stuhr et al (1997); the coronal rhytidectomy associated with the walking suture adopted by McCallum and Welser (2004) and more recently the bilateral crescent-shape section of skin removal in the supraorbital region associated with shortening of the palpebral fissure (STEINMETZ, 2015), it was noted that none of these techniques would be effective in the present case
