Maxillary reconstruction with a palatal fenestration improves prosthetic stability and oral function after extensive surgery. This technique enhances mastication and speech for patients with maxillary defects, particularly the edentulous.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Reconstructive Surgery
  • Biomaterials Science

Background:

  • Maxillary reconstruction is crucial for oral function post-surgery.
  • Prosthetic instability is a challenge after extensive palatomaxillary resection, especially in edentulous patients.
  • Current methods may not adequately address prosthetic retention in complex cases.

Purpose of the Study:

  • To evaluate a novel microvascular maxillary reconstruction technique using a slit-shaped palatal fenestration.
  • To assess the stability and functional outcomes of maxillary prostheses retained by this method.
  • To determine the efficacy of this approach in improving mastication and speech.

Main Methods:

  • Five patients with subtotal or total maxillectomy underwent microvascular reconstruction using rectus abdominis musculocutaneous flaps.

  • A slit-shaped fenestration was created in the hard palate, integrated with the flap for nasal lining and palate reconstruction.
  • Postoperative maxillary prostheses featured a projection designed to engage the palatal fenestration for retention.

    • Main Results:

    • The described reconstruction technique resulted in stable maxillary prostheses in all patients.
    • The prostheses effectively enabled mastication and prevented nasal regurgitation.
    • Speech function was rated as excellent using Hirose's scoring system for Japanese speech ability.

    Conclusions:

    • Microvascular maxillary reconstruction with a palatal fenestration offers a simple and reliable solution for prosthetic retention.
    • This technique significantly improves oral function, including mastication and speech, in patients with challenging maxillary defects.
    • The method provides enhanced stability for maxillary prostheses, addressing a key limitation in post-resection rehabilitation.
