Lower Eyelid Reconstructive Surgery and Resection of Sebaceous Adenocarcinoma in a Dog.
A nine year old male Doberman dog was presented with mass in lower eyelid (OD). Complete tumor excision was performed under general anaesthesia. The extent of skin loss in the lower eyelid required reconstruction, so H blepharoplasty or sliding skin flap technique was performed. Successful treatment of lower eyelid mass was achieved by surgical removal and no recurrence was noticed later. The mass was histopathologically diagnosed as sebaceous gland adenocarcinoma. A 'H blepharoplasty' resulted in satisfactory cosmetic and functional outcome.

The eyelid is a common site for neoplastic diseases in dogs (Bedford, 1999). Eyelid tumors are benign or malignant and importance of appropriate therapy should be considered, in view of ocular discomfort that it causes and because of its potential to impair vision (Willis and Wilkie, 2001). Reconstructive blepharoplasty is indicated when surgical excision has removed more than one third of eyelid margin. It should be remembered that eyelid skin is soft, surrounding facial skin is relatively inelastic and may not stretch readily to provide donor skin. If the eyelid mass involves less than about one third of eyelid margin, removal can be performed in routine fashion (Slatter, 2008). If the mass involves more than one third of eyelid margin and reconstruction of eyelid will be necessary (Rizk Awad, 2012).
The case report describes reconstructive surgery of lower eyelid with sliding H blepharoplasty technique after surgical excision of sebaceous gland adenocarcinoma in a Doberman dog.
A nine year old male Doberman dog weighing 40kg b. wt. was presented with right lower eyelid mass. The mass had been present for last three months but recently had increased in size. The dog was good, detailed ophthalmic examination and hematologic test appeared normal except mass of lower eyelid (Fig.1).
The dog underwent aseptic surgery, premedication with Atropine and Xylazine @ 0.04 mg/kg and 1 mg/kg b. wt. intramuscularly. Analgesia with Tramadol @ 4 mg/kg of b.wt. intravenously. Induction with Diazepam and Propofol anaesthetic @ 0.3 mg/kg and 5 mg/kg of b.wt. intravenously and maintenance with Isoflurane @ 2%. Complete excision of tumor was carried out. Since excision of mass involved a significant loss of tissue. Reconstruction surgical technique was demanded for lower eyelid (H blepharoplasty) (Fig. 2).
The incisions were extended vertically for twice the height of excised portion. Triangular pieces of skin were excised at end of each incision. These triangles facilitated closure without skin folds. The sides of triangle approximately height of excised portion. Surrounding skin was undermined with scissors to provide skin mobility. Skin closure was begun at eyelid margin using 3-0 polyglycolic acid (PGA). The flap was sutured to underlying conjunctiva along eyelid margin with 3-0 PGA in simple continuous pattern. Post-operatively, the dog was given to Tab. Cefotaxime 500 mg @ 22 mg/kg b.wt. b.i.d and Tab. Prednisolone 2 mg/kg b.wt. for five days. Tumor mass was histopathologically diagnosed as Sebaceous gland adenocarcinoma showing irregular multilobulated appearance of several layers of germinative sebocytes (Fig. 3).
The wound healed by first intention and sutures were removed on 11th post-operative day. The dog completely recovered and no complication or recurrence was observed. Reconstruction of lower eyelid by H blepharoplasty resulted in satisfactory cosmetic and functional outcome.
Successful surgical treatment of lower eyelid sebaceous gland adenocarcinoma can be achieved by H blepharoplasty (Ramani et al., 2014). In this case, reconstruction of lower eyelid by sliding skin flap H blepharoplasty resulted in satisfactory functional tear well and cosmetic outcome (Fig. 4).
