Abstract
The pterygoideus proprius muscle can be found incidentally in the infratemporal fossa, where it is spatially associated with the muscles of mastication, the maxillary artery, and the trigeminal nerve and its branches. Anatomists have described the muscle in various ways over the past 160 years, chiefly as a musculotendinous structure that originates from the infratemporal crest of the sphenoid bone and inserts into the lateral pterygoid plate and the lateral pterygoid muscle. It is present in non-human primates, albeit rarely, with similar anatomical findings. Embryologically, the pterygoideus proprius is thought to have developed from the first pharyngeal arch mesenchyme along with other muscles of mastication. Its close association with the maxillary artery and trigeminal nerve suggests possible clinical significance in trigeminal neuralgia and temporomandibular joint disorders. The literature was reviewed systematically to detail the historical background of research on the pterygoideus proprius muscle and explain its morphology, prevalence, embryology, and potential clinical significance. Despite its rarity, we propose that it is important to recognize its presence when the infratemporal fossa is approached.
期刊介绍:
Clinical Anatomy is the Official Journal of the American Association of Clinical Anatomists and the British Association of Clinical Anatomists. The goal of Clinical Anatomy is to provide a medium for the exchange of current information between anatomists and clinicians. This journal embraces anatomy in all its aspects as applied to medical practice. Furthermore, the journal assists physicians and other health care providers in keeping abreast of new methodologies for patient management and informs educators of new developments in clinical anatomy and teaching techniques. Clinical Anatomy publishes original and review articles of scientific, clinical, and educational interest. Papers covering the application of anatomic principles to the solution of clinical problems and/or the application of clinical observations to expand anatomic knowledge are welcomed.
