Pterygomandibular Space

The Pterygomandibular Space is an anatomical area located in the oral cavity. It is a potential space that is clinically significant in dentistry, particularly in the administration of local anesthesia.

Etymology[edit | edit source]

The term "Pterygomandibular" is derived from the Greek words "pteryx" meaning wing and "mandibula" meaning jaw. This term refers to the anatomical location of this space, which is between the pterygoid process of the sphenoid bone and the mandible.

Anatomy[edit | edit source]

The Pterygomandibular Space is a triangular-shaped space located between the mandible and the medial pterygoid muscle. It is bounded anteriorly by the pterygomandibular raphe, posteriorly by the parotid gland, medially by the medial pterygoid muscle, and laterally by the mandible. The space contains the inferior alveolar nerve, the lingual nerve, and the sphenomandibular ligament.

Clinical Significance[edit | edit source]

The Pterygomandibular Space is of particular importance in dentistry. It is the site where local anesthetic is often administered prior to dental procedures, specifically those involving the lower teeth. This is known as an inferior alveolar nerve block. The anesthetic is injected into the Pterygomandibular Space to numb the area and prevent pain during the procedure.
