Purpose
To clearly delineate the anatomy of the musculus longus capitis, determine its clinical applications for reconstruction surgery, and provide a safer surgical method of developing the longus capitis muscle flap.
Methods
Anatomical investigations were performed in seven adult cadavers (five cadavers for gross anatomy and two for transparent specimen preparation) with respect to the location, morphology, arterial supply, and innervation of the musculus longus capitis, as well as its spatial relationship with the cervical sympathetic trunk, superior cervical ganglion, carotid sheath, and other surrounding structures.
Results
The musculus longus capitis is located anterior to the C1–6 vertebrae, segmentally supplied by branches of the ascending cervical artery, innervated by the C1–5 nerve, and spatially close to the cervical sympathetic trunk, superior cervical ganglion, and carotid sheath. These anatomic findings indicate that the development of a cranial or caudal pedicled longus capitis muscle flap is feasible.
Conclusion
The musculus longus capitis can be developed into a cranial or caudal pedicled flap for repair of head and neck defects with negligible morbidity of the donor site.
