Anatomic study of the musculus longus capitis flap.

Area of Science:

• Anatomy
• Surgical Reconstruction
• Head and Neck Surgery

Background:

• The musculus longus capitis is a deep neck muscle with potential for reconstructive surgery.
• Detailed anatomical understanding is crucial for safe flap harvesting.

Purpose of the Study:

• To delineate the anatomy of the musculus longus capitis.
• To explore its clinical applications in reconstruction surgery.
• To establish a safer surgical method for developing the longus capitis muscle flap.

Main Methods:

• Anatomical investigations were conducted on seven adult cadavers.
• Gross anatomy and transparent specimen preparation were utilized.
• Evaluated location, morphology, vascular supply, innervation, and surrounding structures.

Main Results:

• The musculus longus capitis is situated anterior to C1-6 vertebrae.
• It receives segmental arterial supply from the ascending cervical artery and innervation from C1-5 nerves.
• The muscle is in close proximity to the cervical sympathetic trunk, superior cervical ganglion, and carotid sheath.

Conclusions:

• The anatomical findings support the feasibility of developing cranial or caudal pedicled longus capitis muscle flaps.
• This muscle flap can be utilized for repairing head and neck defects.
• Donor site morbidity is negligible, making it a viable option for reconstruction.
