Summary
The iliac crest free flap is a well-established microvascular method for maxillomandibular reconstruction. This study reviews its effectiveness and discusses donor site complications, offering valuable insights for maxillofacial surgeons.
Area of Science:
- Oral and Maxillofacial Surgery
- Microsurgery
- Reconstructive Surgery
Background:
- Microvascular free flaps, including the iliac crest flap, have been pivotal since the 1980s for reconstructing extensive maxillomandibular bone defects.
- These flaps offer superior aesthetic-functional rehabilitation compared to conventional and implant-supported prostheses for complex disablements.
Purpose of the Study:
- To retrospectively analyze the authors' experience with iliac crest flap use in maxillomandibular reconstruction.
- To review international literature on donor site morbidity and compare it with their own findings.
Main Methods:
- Retrospective analysis of maxillomandibular reconstruction cases using the iliac crest flap.
- Detailed discussion of the surgical technique for flap preparation.
- Literature review of donor site complications and comparison with institutional experience.
Main Results:
- The iliac crest flap donor site is associated with potential complications such as chronic pain, sensory loss, hematoma, seroma, gait disturbance, scarring, hernia, and hip contour deformity.
- These complications are consistent with findings reported in international studies.
Conclusions:
- The iliac crest free flap remains a robust technique for microvascular reconstruction of complex maxillomandibular deficits.
- While reconstructive outcomes are well-documented, a comprehensive understanding and discussion of donor site morbidity are crucial for patient care.
