Purpose:
To describe the outcomes of acellular fish skin grafts for repair of periocular anterior lamella skin defects after Mohs surgery for skin cancers.
Methods:
Following the institutional review board approval, the authors conducted a retrospective chart review of patients treated with acellular fish skin grafts between January 2022 and December 2023. Indication was to repair defects after Mohs excision of basal cell carcinoma and squamous cell carcinoma. Demographics, smoking and diabetes status, diagnosis, defect location, graft size, and complications were evaluated. Outcomes were analyzed using the scar cosmesis assessment and rating scale.
Results:
Six patients (3 females and 3 males) with a mean age of 60.8 (range 44-80) had Mohs surgery for basal cell carcinoma (4) and squamous cell carcinoma (2). Location of defects included eyebrow (3 cases), lateral nasal wall (1 case), lower eyelid (1 case), and medial lower eyelid/nasal wall (1 case). Defect size ranged from 8 × 10 mm to 30 × 40 mm. Two patients had more than 1 application of xenograft. One patient developed a mild cicatricial ectropion. No other postoperative complications were seen, and all had good wound healing and cosmetically acceptable results.
Conclusions:
In this pilot study, acellular fish skin xenografts are shown to be promising skin graft substitutes in patients with Mohs defects and decrease the need for autologous skin harvesting or allogenic skin donation.
