Abstract

Since hyperplastic aponeurosis and tendons cause limited muscle extension, patients with masticatory muscle tendon-aponeurosis hyperplasia (MMTAH) experience a limited mouth opening ability due to restrictions in muscle extension. Therefore, this article discusses five patients of MMTAH who underwent bilateral aponeurotomy combined with coronoidectomy in our department.
