Ultrasound Guided Injection for Medial and Lateral Pterygoid Muscles: A Novel Treatment for Orofacial Pain

Landmark of Ultrasound-Guided Trigeminal Block: Lateral Pterygoid Muscle.

I read with great interest the recent article by Antoun Nader and colleagues (1) and a similar technique present in another article (2). From an anatomical point, insertion into the lateral pterygoid muscle is on the lateral pterygoid plate and the origin is the mandible. From the computed tomography image (3), we can understand that the lateral pterygoid muscle can be detected by ultrasound be...

Lateral pterygoid muscle and maxillary artery are key anatomical landmarks for ultrasound-guided trigeminal nerve block.

Myositis Ossificans Traumatica of Lateral and Medial Pterygoid Muscles: a Case Report

A 19 years male patient came to the Oral and Maxillofacial Surgery outpatient department with chief complaint of progressively reducing mouth opening for the past four months. History, clinical and radiological examination strongly suggested it to be a rare case of myositis ossificans traumatica which was subsequently confirmed histopathologically. The patient was managed by extirpation of the ...

myositis ossificans of the medial pterygoid muscles: a case report

myositis ossificans (mo) is a pathologic bone formation in soft tissue with unknown pathogenesis. in this article, we reported a case of long standing mo of right medial pterygoid muscle with severe limitation of mouth opening.

Myosin isoform composition of the human medial and lateral pterygoid muscles.

The medial and lateral pterygoid muscles are different in structure as well as in function. The medial pterygoid muscle is concentrically active during jaw closing, and the superior head of the lateral pterygoid muscle is eccentrically active during jaw closing, while its inferior head is concentrically active during jaw opening. Architecturally, the medial pterygoid can deliver higher forces t...
