Surgical Anatomy of Mastication: Fascial Spaces, Nerve Blocks, and Infection Pathways

In this clinical guide, we break down the applied anatomy of the masticatory apparatus and its role in deep fascial space infections. Learn the structural relationships of the **primary muscles of mastication**—the **masseter, temporalis, medial pterygoid, and lateral pterygoid**—along with their shared nerve supply (**mandibular nerve**) and vascular routes (**maxillary artery**). We explore how the superficial and deep heads of the masseter create pathways for submasseteric space infections, clinical presentations like trismus, and key landmarks for surgical drainage #oralsurgery ` `#MaxillofacialSurgery` `#ClinicalAnatomy` `#DeepSpaceInfection` `#MusclesOfMastication` `#MasseterAnatomy` `#DentalEducation` `#HeadAndNeckAnatomy`
