Coronal Rhytidectomy for Correction of Bilateral Superior Entropion in Dogs with Redundant Eyebrow Droop - A Review of Two Cases

Abstract

Various degrees of entropion defects with redundant skin folds due to conformational defects are common in Chow Chow and Shar Pei breeds of dogs. The irritation caused by the eyelid and hairs on the conjunctiva results in lacrimation and blepharospasm. In severe cases, as the dogs reach 7-8 months of age the complications of this extreme entropion result in a corneal ulcer. Temporary tacking of the facial folds was resorted to augment the corneal healing and to assess the size of the skin to be removed later. Surgical excision of wrinkles - rhytidectomy was done as radical surgery and was found satisfactory. The area of natural tension lines along the wrinkles in the coronal region was marked before excision and for a good cosmetic outcome. This paper describes the need for a rhytidectomy -excision of large facial skin folds- in Chow Chow and Shar Pei breeds of dogs to correct bilateral superior total entropion
