Oromandibular reconstruction using a fibula osteocutaneous free flap: four different "preplating" techniques.

Background: The aim of oromandibular reconstruction following a partially or fully extended resection is to recreate the normal morphology with a mandibular profile as similar as possible to the original and to restore oral function. Oromandibular reconstruction can be performed with fibula osteocutaneous free flaps combined with the preplating technique. The authors report their experience using the preplating technique for oromandibular reconstruction.

Methods: Four different methods can be used to mold the titanium plate that will be used in reconstruction against the existing mandible before resection. The preplating technique was used in 18 patients between 1998 and 2003. In eight patients, the external cortical bone of the mandible was spared by the tumor and the vestibular preplating technique was used. In one patient, the internal cortical bone was unaffected and the lingual preplating technique was used. When the tumor affected both the internal and external cortical bones, the double preplating technique was adopted in eight cases and Luhr's approach was used in one case.

Results: A good cosmetic appearance was obtained through the accurate reconstruction of the inferior mandibular border. Mandible continuity was restored, and the masticatory and oral muscles were anchored to the titanium plate, resulting in good occlusal and functional rehabilitation.

Conclusion: The preplating technique combined with a fibula microvascular free flap is a useful, predictable method for oromandibular reconstruction.
