Background:
Reconstruction of the head and neck is dominated by free flaps, and for bone reconstruction by fibula and scapula flaps. However, this choice is sometimes difficult to make in patients who cannot tolerate an extensive and lengthy surgical procedure. In addition, vascular micro-anastomoses are sometimes complicated in patients who have been previously irradiated. Pedicle flaps remain an option and can sometimes be considered as first choice for head and neck reconstruction.
Purpose:
In this study, we describe the feasibility of a split temporal muscle pedicled flap with coronal harvesting for a reconstruction that can reach the midline.
Study Design Sample Covariates:
Ten fresh-frozen human cadaver heads were dissected, and the length of the split flap was noted, followed by the length of the non-split flap.
Results:
The mean length was 155.7 mm (± 20.0) for the split flap, from the point of rotation to the tip of the coronoid process. These results coincide with the tragus-midline distance, which makes it possible to consider reconstruction of the midline, especially the maxilla and the mandible, which has not yet been described in the literature.
Conclusions And Relevance:
This technique would then allow a supply of pedicled vascularized bone for loco-regional reconstruction.
