Hypoglossal nerve palsy or paralysis is an occasional but clinically serious disorder that results from affecting the hypoglossal nerve (cranial nerve XII). The tongue’s intrinsic and extrinsic muscles, which are mostly supplied by this nerve, are essential for speaking, swallowing, and keeping the airway’s purity. These abilities can be severely impaired by damage to the hypoglossal nerve….

Introduction The facial muscles, also known as craniofacial muscles, are a group of approximately twenty flat skeletal muscles that are located beneath the skin of the scalp and face. The majority of them originate in the skull’s bones or fibrous structures before spreading to the skin. The facial muscles are a collection of striated skeletal…
Spinal Accessory Nerve Palsy, also known as Accessory Nerve Palsy, is a neurological condition characterized by the dysfunction of the spinal accessory nerve (cranial nerve XI). This nerve is primarily responsible for innervating the sternocleidomastoid and trapezius muscles, which are essential for head rotation, shoulder elevation, and certain movements of the neck and scapula. Damage…

Definition for Cubitus Varus Deformity Cubitus varus deformity, often referred to as “gunstock deformity,” is a condition characterized by an inward angulation of the extended elbow. This deformity typically arises as a complication following supracondylar fractures of the humerus, particularly in children.Cubitus valgus is the “opposite” condition. This is a trilobate asymmetry of the elbow,…
