The five-point eight-line segment (FIPELS) flap design improves hemiglossectomy reconstruction outcomes. This novel technique enhances function and aesthetics compared to conventional methods.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Plastic Surgery
  • Head and Neck Surgery

Background:

  • Reconstructing hemiglossectomy defects is challenging, requiring precise flap design to optimize functional and aesthetic results.
  • Adverse outcomes can occur if flap design does not adequately address the defect.
  • Minimizing functional deficits and improving cosmetic appearance are key goals in tongue reconstruction.

Purpose of the Study:

  • To introduce and evaluate a novel flap design for hemiglossectomy reconstruction.
  • To compare the efficacy of the five-point eight-line segment (FIPELS) flap design against conventional methods.
  • To assess functional and aesthetic outcomes following hemiglossectomy reconstruction using the FIPELS technique.

Main Methods:

  • Hemitongue specimens from minipigs were used to study 3D anatomy and identify landmarks for flap design.

  • The FIPELS flap design concept was developed based on animal model findings.
  • Sixty-one patients with hemiglossectomy defects were randomized into FIPELS (28 patients) and conventional (33 patients) flap design groups.

    • Main Results:

    • Flaps designed with the FIPELS technique precisely matched hemiglossectomy defects, eliminating the need for trimming and reducing operative time (P=.03).
    • Patients in the FIPELS group demonstrated superior swallowing function compared to the conventional group (P<.05).
    • Speech intelligibility and aesthetic outcomes were significantly better in the FIPELS group than in the conventional group (P<.05).

    Conclusions:

    • The FIPELS flap design offers a significant improvement for hemiglossectomy reconstruction.
    • This technique leads to enhanced functional recovery, including better swallowing and speech.
    • The FIPELS method provides superior aesthetic results compared to conventional flap designs in hemiglossectomy reconstruction.
