Axial Pattern Flap Based on the Superficial Temporal Artery in Cats: An Experimental Study
Veterinary Surgery, 1997
The purpose of this study was to determine the surgical guidelines for and the survivability of an axial pattern flap based on the superficial temporal artery in cats. Study Design-The mean survival length and mean percentage area of survival of flaps after 7 days in control and experimental groups, are assessed and compared. Animals-Ten mature, domestic shorthair cats. Methods-The superficial temporal artery and vein were incorporated in the flaps of the experimental group (n = 5) and were ligated in the control group (n = 5). Seven days postoperatively, the length of tissue that remained viable in each flap was determined by measurement of the length of the grossly devitalized tissue and subtracting this from total flap length. Results-Mean width and length of all flaps was 2.0 X 7.0 cm, respectively. Mean survival length (2SD) of experimental and control flaps was 6.9 (0.2) cm and 4.4 (2.2) em, respectively. Necrosis occurred in all control flaps, resulting in a mean percentage area of survival of 62.8 (1 1.7)%, compared with 98.6 (3.2)% for experimental flaps. Results were significantly different (P < .05) between the experimental and control groups. Conclusions-A flap based on the superficial temporal artery may be a source of skin for reconstructive procedures of the maxillofacial region in cats. Clinical Relevance-Knowledge of the anatomic landmarks and survivability of an axial pattern flap are essential considerations when planning a reconstructive technique.

Bridging the Gap IntRoductIon Reconstruction of auricular defects always remains a very demanding and challenging procedure. Various techniques have been developed depending on the defect size, site and type of tissues involved. Irrespective of the selected technique, auricular reconstruction should aim at deformity correction with the most minimal morbidity as well as the accomplishment of the most pleasing aesthetic outcome. On reviewing the literature, there is little evidence regarding reconstruction of centrally located and full-thickness defects. [1] Aims The aim of this article was to describe in detail the post-auricular folded flap (PAFF), which was utilised for reconstruction of perforating defects of central sites of the auricle in elderly patients with advanced systemic diseases. PAtIents And methods Surgical technique The patient should be positioned and prepped in the similar fashion as for otologic surgery. Thus, supine position is selected, with the head slightly elevated to limit blood loss. PAFF represents an inferiorly based myocutaneous transpositional flap; its base was approximately placed inferiorly or at the same height to the defect, and its long axis was drawn parallel to the auriculocephalic sulcus (ACS). The flap width is marked to be equal with maximal horizontal dimension of defect; its maximum length should be approximately 3-4 times greater of its width. Indeed, the flap length needs to be large enough Background: Post-auricular flaps have proved very effective in the reconstruction of most types of partial auricular defects. However, few reports exist regarding the reconstruction of centrally located perforating defects of the auricle. Objectives: This paper aimed to describe a one-stage technique including a post-auricular folded flap (PAFF) for reconstruction of full-thickness defects of central auricular sites. Patients and Methods: Between March 2010 and November 2014, five male patients were treated with this reconstructive technique under local anaesthesia. At the time of surgery, patients' age ranged from 76 to 86 years (mean age, 79.8). The patients suffered from a central and full-thickness defect owing to surgical excision of a skin malignancy or failed reconstruction procedures secondary to surgical excision of a skin malignancy. Results: Healing was uneventful for all the included patients, without signs of dehiscence, necrosis, hematoma and infection. The defects were completely repaired, without the need of further operations. During the follow-up period, all the patients remained satisfied with the aesthetic outcome. Conclusions: This technique constitutes an immediate, effective and low-morbidity procedure to repair full-thickness central defects of the auricle. Since PAFF requires only one surgical operation under local anaesthesia, patients with burdened medical history may profit from this technique.
