Area of Science:

  • Surgical Oncology
  • Reconstructive Surgery
  • Head and Neck Surgery

Background:

  • Extensive lateral skull base defects pose significant reconstructive challenges.
  • Malignant neoplasms often necessitate complex surgical interventions leading to these defects.
  • Primary closure is frequently not feasible for such large surgical defects.

Purpose of the Study:

  • To evaluate surgical reconstructive options for extensive lateral skull base defects.
  • To analyze the complications associated with these reconstructive procedures.
  • To assess the reliability of different flap techniques in managing these complex cases.

Main Methods:

  • Retrospective case review of 11 patients with malignant lateral skull base neoplasms.
  • Surgical extirpation followed by reconstruction using free tissue transfer or rotational flaps.

  • Analysis of defect closure, healing, intraoperative/postoperative complications, and patient survival.

    • Main Results:

    • Eleven patients (8 male, 3 female, average age 65) underwent reconstruction.
    • Trapezius flap (n=8), temporalis flap (n=1), and rectus abdominis free flaps (n=2) were utilized.
    • One perioperative death (cardiac), no immediate wound complications, and one delayed partial trapezius flap failure successfully managed.

    Conclusions:

    • The trapezius rotational flap is a dependable method for reconstructing complex lateral skull base defects.
    • This technique is associated with minimal patient morbidity.
    • Successful reconstruction can be achieved with careful patient selection and surgical planning.
