Study highlights modified blepharoplasty for canine, feline eyelids: full analysis

A retrospective study covering 18 dogs and cats treated from 2018 to 2025 suggests a modified house-inverted-triangle blepharoplasty may be a useful addition to the eyelid reconstruction toolkit after tumor resection or other eyelid defects. Published in the Journal of Small Animal Practice, the study reported good-to-excellent cosmetic and functional outcomes in every case, with two-thirds graded excellent. The authors say the technique was effective even for large or complex defects, including those involving the medial canthus. (mendeley.com)

That finding is notable because eyelid reconstruction in small animal practice sits at the intersection of oncology, ophthalmology, and soft tissue surgery. As a longstanding review on eyelid neoplasms notes, resection may be curative, but reconstruction is essential to preserve eyelid function and ocular surface health. The clinical context also differs by species: eyelid neoplasms are common in older dogs and are typically benign, while they are less common in cats and more often malignant, which can raise the stakes around margins, defect size, and postoperative lid function.

The new study, authored by L. Zuzzi-Krebitz, L. Schweitzer, and B. K. Braus, reviewed 18 cases, 12 dogs and six cats, in which the modified technique was used for eyelid reconstruction following tumor removal or other defects. Based on available abstracts and indexing pages, the reported endpoint was clinical outcome, with all cases achieving either good or excellent cosmetic and functional results. Wiley-indexed summaries describe the procedure as a “modified house-inverted-triangle blepharoplasty,” while secondary indexing characterizes it as versatile for large and complex defects, including the medial canthus. Because the full article text was not openly available in the sources reviewed, details such as exact complication rates, follow-up intervals, and case selection criteria were limited in public summaries.

The broader literature helps frame where this technique may fit. Veterinary education material has described the classic house-inverted-triangle blepharoplasty as a one-step option for upper or lower eyelid lesions involving roughly 25% to 50% of eyelid length, with the advantage of avoiding a scarred new lid margin at the tumor site, although lateral trichiasis can occur. Other retrospective and case-series reports have expanded reconstructive choices, including temporal H-figure sliding skin flaps for central eyelid neoplasms, glabellar flaps for medial canthal reconstruction in dogs and cats, and lip-to-lid subdermal plexus flaps for lower eyelid defects. In that context, the modified approach appears to be part of a broader move toward tailoring flap design to defect location and size rather than relying on one standard blepharoplasty for all cases.

Direct outside commentary on this specific paper was limited in public sources, but the surrounding literature points to a consistent theme: reconstructive success is judged by function as much as appearance. Recent reports on other eyelid flap techniques have also shown generally favorable outcomes, but with meaningful rates of minor complications such as flap necrosis, dehiscence, blink dysfunction, or trichiasis. That makes the new study’s across-the-board good-to-excellent results encouraging, while also underscoring the need to see the full complication profile and duration of follow-up before drawing broader conclusions.

Why it matters: For general practitioners and specialists alike, this paper is relevant because periocular mass removal often leaves surgeons balancing oncologic principles against the need to preserve corneal protection. A technique that can handle larger defects or medial canthal involvement in a single-stage reconstruction could expand referral and surgical planning options, especially in feline cases where malignancy is more common and tissue preservation can be difficult. It may also help clinicians counsel pet parents more clearly about likely cosmetic and functional outcomes after excision of eyelid tumors. (pubmed.ncbi.nlm.nih.gov)

There are still important caveats. This was a retrospective series with 18 total cases, and publicly available summaries do not yet provide the level of granularity many surgeons will want, including defect sizes, tumor types, margin status, reintervention rates, and long-term ocular surface outcomes. Those details will determine whether the technique is best viewed as a niche option for selected cases or a broader addition to standard reconstructive algorithms. (researchgate.net)

What to watch: Watch for the full paper’s wider availability, conference discussion among veterinary ophthalmologists and soft tissue surgeons, and any follow-on studies that compare this modified blepharoplasty with established options such as H-figure, glabellar, or lip-to-lid flaps in similar defect types.
