Özet
Purpose: Recent bichectomy and face lift operations that prefer an intraoral approach to the region, which puts the buccal nerve at risk. This study aimed to investigate the anatomy of the buccal nerve with an intraoral approach.
Methods: Hemi-faces of 8 cadavers were dissected at Koç University School of Medicine. The heads were cut sagittally with a band saw and dissections were done with a medial approach. The course of the nerve in the pterygomandibular and buccal spaces, its relationship with the temporalis muscle, opening of the parotid duct, and buccal fat pad were evaluated. Nerve’s horizontal and vertical distance to the parotid duct opening, distances of the nerve as it turned anteriorly into the buccal space to the coronoid tip and retromolar trigone, and the horizontal distance between the nerve and the lateral pterygoid plate was measured.
Results: Buccal nerve coursed parallel to the temporalis tendon vertically within the temporalis fascia and pierced the muscle/tendon in 2 specimens. In buccal space it had an antero-inferior course and stayed below the linea alba in all specimens. As it entered buccal space, it gave off numerous branches posterior to the parotid duct opening. Nerve remained lateral to the temporal expansion of the buccal fat pad in pterygomandibular space and medial to the anterior lobe of buccal fat pad in buccal space. Distance of the nerve was 14.1±1.2 mm to the lateral pterygoid lamina, 25.2±2.8 mm to the coronoid tip, and 15±2.2 mm to the retromolar trigone. Horizontal and vertical distances of the nerve to the parotid duct opening were 18.9± 2.4 mm and 16.6± 2.4 mm, respectively.
Conclusion: The buccal nerve had a more close relationship to the temporalis muscle than previously reported. Its anteroinferior course in buccal space and relationships with buccal fat pad are reported for the first time.
