Head and neck reconstruction with dorsoradial forearm free flap: a preliminary clinical study. Problems/Objectives: The most common criticism of the radial forearm free flap (RFFF) is donor site morbidity. Delayed or defected integration of split thickness skin graft (STSG) is the most commonly encountered complication. Defective healing or excessively thin skin coverage of important forearm structures, such as the median nerve and ulnar arterynerve bundle, places these structures at increased risk of injury. The current study aims to modify the RFFF to utilize a dorsoradial skin island in order to protect the volar tissue aspect of these structures.
Methodology: Seven patients were included in the study between 2005 and 2008. All patients had oncologic resections in the oral cavity necessitating free tissue transfer. The main variation from the standard RFFF technique is that the medial incision was placed 1 cm lateral to the palmaris longus tendon. The dissection was extended laterally and dorsally, depending on the necessary flap size. The donor side defect was covered with a thigh STSG. Results: None of the patients had partial or complete flap necrosis. This surgical modification provided tissue coverage along the course of the median nerve and ulnar neurovascular bundle.
Conclusions: Dorsoradial forearm free flap is a feasible technique that allows preservation of tissue coverage on the volar surface of the forearm.
