Abstract

The major basic task of the masseter muscle, which is a quadrangular thick muscle, is to close the jaw by elevating the mandible against the maxilla and performing the biting and chewing functions of the teeth. The masseter muscle slightly involved in lateral movements and mandibular protraction, is one of the four masticatory muscles that are very important in facial aesthetics. In an article published by Mezey et al. in December 2021, it was shown that anatomically, a deep different third layer of the masseter muscle extends from the medial surface of the os temporale processus zygomaticus to the posterior edge and root of the coronoideus. It has been suggested that this structure, called the masseter pars coronoidea, is a third and new part of the masseter muscle. This study, as well as being quite interesting in the scientific world, also brought up the existence of some question marks and caused reactions. In this study, it was aimed to review the embryological development, anatomical and histological structures of the masseter muscle from the past to the present in the light of current knowledge and to address the debate on the masseter muscle, which was presented to the scientific world as a new definition, in all aspects.

Özet

Dörtgen şeklinde kalın bir kas olan masseter kasının en temel görevi mandibula’yı maxilla’ya karşı eleve etmek, dişlerin ısırma ve çiğneme işlevlerini gerçekleştirmek suretiyle çeneyi kapatmaktır. Lateral hareketlerde ve mandibula protraksiyonunda az da olsa görev alan masseter kası, esasen yüz estetiğinde oldukça önem arz eden dört çiğneme kasından biridir. Aralık 2021’de Mezey ve ark.ları tarafından yayınlanan bir makalede, anatomik olarak, masseter kasına ait derin farklı üçüncü bir tabakanın os temporale processus zygomaticus medial yüzeyinden, coronoideus posterior kenarına ve köküne doğru uzandığı gösterildi. Masseter pars coronoidea olarak adlandırılan bu yapının masseter kasına ait üçüncü ve yeni bir parça olduğu ileri sürüldü. Bu çalışma, bilim dünyasında oldukça ilgi çekici bulunduğu kadar, beraberinde bazı soru işaretlerinin varlığını da gündeme getirmiş ve tepkilere neden olmuştur. Sunulan bu çalışmada, geçmişten günümüze masseter kasının, embriyolojik gelişimleri ile anatomik ve histolojik yapılarının güncel bilgiler ışığında gözden geçirilmesi ve yeni bir tanımlama olarak bilim dünyasına sunulan masseter kası ile ilgili tartışmanın tüm yönleriyle ele alınması amaçlandı.
