“…The STE could be used as part of planned tissue reconstruction in almost any anatomic location, although previous experimental work in horses has demonstrated that the biomechanical properties of expanded skin using these devices vary at different anatomic locations (Al‐Majhali et al, 2021). The relatively small size of the STE used allowed implantation to be performed via a single incision in most cases.…”

Summary Background Tissue expansion is a well‐established technique in reconstructive surgery. Self‐inflating tissue expanders (STE) have not been widely adopted by veterinary surgeons, and clinical descriptions of their use in horses are lacking. Objective To describe the indications, clinical experiences and outcomes of a series of equine cases that used a hydrogel‐based STE to assist soft tissue reconstruction. Study design Prospective clinical study. Methods Case details, surgical techniques and outcomes were recorded for horses requiring use of an STE, using a predesigned data collection sheet completed by the treating surgeon. All horses underwent two surgical procedures as part of their treatment: one to place the STE(s) and a second to remove the device(s) and perform reconstructive surgery using the expanded tissue. Results Twenty horses had STEs implanted at seven clinics and had sufficient follow‐up for inclusion in the study. Indications for using the expanders included the following: expansion of skin prior to excision of a neoplastic lesion (n = 13), repair of a sinocutaneous fistula (n = 2), repair of chronic scarring or a nonhealing wound (n = 2), repair of a full‐thickness ear pinna defect (n = 1) and repair of a rectovestibular injury (n = 2). The degree of tissue expansion was graded as good in 19/20 cases (95%) and provided sufficient tissue to cover the entire defect in 11/20 cases (55%). STE‐associated complications occurred in 9/20 horses (45%), but none of these complications were serious. The final clinical outcome was graded by the treating surgeon as good or excellent in 15/20 horses (75%). Main limitations Only one type of STE device is described, and its use was not compared with other treatments. Information regarding use of the STE at locations other than the head (n = 3) is limited. Conclusions Use of a STE device in horses resulted in no serious complications and provided a good outcome in a variety of equine clinical cases.

“…Thus, healing is characterised by excessive scar formation resulting in deformation of the injured area. Although skin grafting has been used to fill the skin defect, however, tissue expansion technique has been proposed as an alternative technique to skin grafting because it is more favourable in terms of higher success rates and cosmetic results since the defect is replaced with analogous tissue with matching texture, colour and other important local features (Agrawal & Agrawal, 2012;Al-Majhali et al, 2021;Whittaker et al, 2020).…”

The tissue expansion technique is one of the most important innovations in skin reconstructive surgery in human and veterinary medicine. This study investigated horses’ physiological and behavioural responses to subcutaneous implantation of a unidirectional self-inflating anisotropic tissue expander. The tissue expanders were subcutaneously implanted on six horses at three different locations: the frontal region of the head, the lateral side of the right shoulder, and the dorsomedial part of the cannon region of the right forelimb. Prior to the tissue expander implantation, each horse was clinically examined, and the observed vital parameters and behaviour were recorded as baseline data. For six days post implantations, the horses were clinically examined, implantation sites monitored, and the horse’s behaviour was recorded both during the day by visual observation and at night with a video camera. The results showed that all horses tolerated the subcutaneous gradual skin expansion by implantation of the tissue expanders, and all surgical sites healed without any complications. The implantation of the tissue expanders does not affect the vital parameters or overall horse behaviour either during the day or at night. In conclusion, the subcutaneous implantation of unidirectional anisotropic tissue expanders in horses resulted in successful skin growth with no physiological and psychological discomfort; hence skin expansion is a good option to be considered when pursuing equine skin reconstructive surgery.
