Where is submandibular space?
The submandibular space extends from the hyoid bone to the mucosa of the floor of the mouth, and is bound anteriorly and laterally by the mandible and inferiorly by the superficial layer of the deep cervical fascia.
What are the borders of the submandibular space?
The submandibular space is bounded anteriorly and laterally by the mandible, medially by the anterior belly of the digastric muscles, superiorly by the mylohyoid muscle and inferiorly by the hyoid bone (Figs.
What is pterygomaxillary fissure?
The pterygomaxillary fissure is a fissure of the human skull. It is vertical, and descends at right angles from the medial end of the inferior orbital fissure. It is a triangular interval, formed by the divergence of the maxilla from the pterygoid process of the sphenoid.
