Abstract

AIM: The masseter muscle is often exploited by craniofacial surgeons in transposition operations to correct facial palsy, benign masseteric hypertrophy; or neurectomy-induced atrophy of the muscle. A clear understanding of the course of the premasseteric branch of the facial artery and its relations with adjacent structures is essential in maneuvering the masseter muscle safely. In the present study the premasseteric branch was analyzed in details. MATERIAL and METHODS: Neurovascular and anatomical features and relations of the premasseteric branch and its branches were evaluated according to location, origin, diameter, length and course by bilateral meticulous anatomic micro dissection under 4x loop magnification in formalin fixed 14 adult preserved cadavers. RESULTS: The premasseteric branch originated separately from the facial artery in all cases. The course of the branch was observed to the upper anterior border of the masseter muscle. The diameter of the premasseteric branch was 1.12 mm (mean) at the level of origin. The diameter of the premasseteric branch was larger than the facial artery in 3% of cases. The location of the branch was defined according to body of the mandible. Branches and anastomoses of the premasseteric branch were also represented. CONCLUSION: Anatomical data of the premasseteric branch will help craniofacial surgeons elevate flaps safely.

Özet

AMAÇ: M. masseter, kraniofasiyal cerrahlara fasiyal palsi, benign masseter hipertrofisi, kraniofasiyal travma, nörektomi sonrası kas atrofisinin düzeltilmesi operasyonlarında büyük avantaj sağlar. Transpozisyon operasyonlarında kasın, kendisini besleyen a. facialis'in dalı olan ramus premassetericus'la birlikte güvenle taşınabilmesi için bu dalın seyrinin anlaşılması büyük önem taşır. Bu amaçla çalışmamızda, ramus premassetericus'un detaylı olarak incelenmesine çalışılmıştır. YÖNTEM ve GEREÇ: 14 erişkin formalin ile fiske edilmiş kadavrada (12 erkek, 2 kadın; 55-82 yaşları arasında; 27 olgu: 14 sol-13 sağ taraf) anatomik mikrodiseksiyon yöntemiyle 4x büyüteç kullanılarak ramus premassetericus ve dalları ortaya konuldu. R. premassetericus yerleşim, orijin, çap, uzunluk ve seyir özellikleri, musculus masseter ve ductus parotideus ile ilişkisi yönleriyle değerlendirildi. BULGULAR: Dalın m. masseter'in üst kenarı boyunca seyrettiği gözlendi. Dalın başlangıç noktası seviyesinde çapı ortalama 1,12 mm olarak saptandı. %3 olguda dalın çapı, a. facialis'in çapından daha büyüktü. Dalın yerleşimi corpus mandibula'ya göre belirlendi.R. premassetericus'un dalları ve anastomozları da ortaya konuldu. SONUÇ: Ramus premassetericus'a ait verilerin kraniyofasiyal cerrahlara flaplerin güvenli kaldırılmasında yardımcı olacağı düşüncesindeyiz.
