A modified T-shaped closure technique effectively repairs large rostral maxillary defects in dogs after cancer surgery. This method reduces tension and improves cosmetic outcomes for veterinary surgical oncology patients.

Area of Science:

  • Veterinary Surgery
  • Oral and Maxillofacial Surgery
  • Veterinary Oncology

Background:

  • Rostral maxillary defects resulting from cancer surgery pose significant closure challenges.
  • Standard closure techniques may be insufficient for larger defects, impacting functional and cosmetic outcomes.
  • Maxillary neoplasms often require extensive surgical resection, leading to complex post-operative defects.

Purpose of the Study:

  • To describe a modified T-shaped closure technique for large rostral maxillary defects.
  • To evaluate the efficacy and outcomes of this novel surgical approach in dogs.
  • To address limitations of standard closure methods in veterinary oral surgery.

Main Methods:

  • A retrospective study evaluated 23 dogs undergoing rostral maxillectomy with a modified T-shaped closure.

  • Procedures included bilateral incisivectomy and unilateral or bilateral rostral maxillectomy.
  • Data collected from January 2015 to January 2023 at a specialized veterinary dental center.

    • Main Results:

    • The modified T-shaped closure facilitated primary mucosal closure of large rostral maxillary defects.
    • The technique demonstrated decreased incision site tension and improved cosmetic results (reduced muzzle concavity).
    • Preservation of vestibule size and critical vasculature was noted, with successful outcomes reported.

    Conclusions:

    • The modified T-shaped closure is a viable technique for managing large rostral maxillary defects post-oncologic surgery in dogs.
    • This method offers advantages in tension reduction, cosmetic appearance, and preservation of anatomical structures.
    • Further research is warranted to definitively validate the success rate and long-term efficacy of this surgical approach.
