Summary

Immediate reconstruction of mandibular defects after cancer surgery is recommended for optimal functional and cosmetic outcomes. Techniques include microsurgical and pedicled flaps, with bone flaps suitable for endosseous titanium implants inserted during oncological surgery.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Oncologic Reconstruction
  • Implantology

Background:

  • Mandibular defects from oncological surgery cause significant functional and cosmetic issues.
  • Reconstruction is crucial for patient rehabilitation and return to daily life.
  • Immediate reconstruction is strongly advocated over delayed procedures.

Purpose of the Study:

  • To analyze and compare various mandibular defect reconstruction techniques.
  • To evaluate the functional and cosmetic outcomes of different reconstruction methods.
  • To assess the role of immediate endosseous implants in mandibular reconstruction.

Main Methods:

  • Comparative analysis of microsurgical flaps, pedicled flaps, and endosseous implants.
  • Evaluation of functional outcomes including speech, deglutition, mastication, and labial competence.

  • Assessment of cosmetic results and long-term survival rates (5 years).

    • Main Results:

    • Immediate reconstruction using microsurgical or pedicled flaps yields favorable cosmetic and functional results.
    • Osteointegrated implants, particularly with bone flaps, enhance masticatory function.
    • All analyzed reconstruction methods demonstrated 5-year patient survival.

    Conclusions:

    • Immediate mandibular reconstruction is recommended for optimal patient outcomes.
    • Microsurgical and pedicled flaps are viable reconstruction options.
    • Endosseous titanium implants, inserted during oncological surgery, improve function; bone flaps are suitable, but osseous flaps lacking rehabilitation guarantee should be avoided. Postoperative radiotherapy can affect osteointegration.
