Only a few anatomic studies of the entire course of the hypoglossal nerve (cranial nerve XII) have been reported. We analyzed all relationships of the 12th nerve with surrounding structures from the brainstem to the tongue through a microscopic perspective. A comprehensive anatomically and clinically oriented classification of its different segments is proposed. ⋯ Classification of 5 segments for the hypoglossal nerve seems anatomically valid, and it is surgically oriented with respect to all surgical approaches. Precise knowledge of the relationships with the surrounding structures may help to prevent some complications during surgery, and it is useful to explain, segment by segment, the pathogenic mechanisms for nerve injuries that are evidenced by lesions that exist along the entire intracranial and extracranial course.

A 26-year-old male had suffered a burn injury to his scalp in childhood and ignored it. He presented with a complaint of something crawling on his head. Inspection of his scalp revealed multiple maggots on the brain surface with erosion of overlying bone and scalp. He was successfully managed by surgical debridement and regular dressing.

Injury to distal portion of posterior cord of brachial plexus leads to palsy of radial and axillary nerves. Symptoms are usually motor deficits of the deltoid muscle; triceps brachii muscle; and extensor muscles of the wrist, thumb, and fingers. Tendon transfers, nerve grafts, and nerve transfers are options for surgical treatment of proximal radial nerve palsy to restore some motor functions. Tendon transfer is painful, requires a long immobilization, and decreases donor muscle strength; nevertheless, nerve transfer produces promising outcomes. We present a patient with proximal radial nerve palsy following a blunt injury undergoing triple nerve transfer. ⋯ Our experience confirmed functional elbow, wrist, and finger extensions in the patient. Triple nerve transfer restores functions of the upper limb in patients with debilitating radial nerve palsy after blunt injuries.

Comparative Study
Comparison of chronic Dysphagia in Standalone versus Conventional Plate and Cage Fusion.
Standalone cages have gained popularity because of their ease of implantation, reduced operating time, and lower profile compared with traditional plate and cage systems. The aim of this study was to compare the risk of chronic dysphagia between those who undergwent anterior cervical discectomy and fusion (ACDF) with traditional plating techniques and those who underwent standalone procedures. ⋯ Despite similar mean DDI scores, patients who undergo anterior cervical discectomy with a plate-cage may be at a higher risk for chronic dysphagia than are those with a standalone approach, but further studies with larger sample sizes are necessary to establish this relationship with greater confidence.

Chronic subdural hematoma (CSDH) is a commonly encountered neurosurgical pathology that frequently requires operative intervention. With an increasing ageing demographic, more elderly and comorbid patients will present with symptomatic CSDH. This study evaluated clinical and radiologic factors to create a scoring system to aid prognostication. ⋯ A scoring system has been devised to predict outcome, which can aid in the necessity of surgery in certain patient demographics.
