INTRODUCTION: Cutaneous nerves have branches called vascular branches (VBs) that reach arteries. VBs are thought to be involved in arterial constriction, and this is the rationale for periarterial sympathectomy as a treatment option for Raynaud's disease. However, the branching patterns and distribution areas of the VBs remain largely unclear. The aim of the present study was to investigate the anatomical structures of the VBs of the cutaneous nerves. MATERIALS AND METHODS: Forty hands and forearms were examined to assess the branching patterns and distribution areas of the VBs of the superficial branch of the radial nerve (SBRN), the lateral antebrachial cutaneous nerve (LACN), the medial antebrachial cutaneous nerve (MACN), and the palmar cutaneous branch of the ulnar nerve (PCUN)...

We report a patient in whom mechanical compression of the internal carotid artery by a giant external carotid artery pseudoaneurysm caused a stroke. This was a case of vascular Eagle syndrome due to the impingement of an elongated styloid process on the external carotid artery with subsequent dissection and formation of a pseudoaneurysm. Carotid ultrasonographic examination allowed distinguishing the pseudoaneurysm from other vascular and solid masses of the neck.

The presence of a septum in the first extensor compartment is closely associated with the pathophysiology of de Quervain disease, and affects the efficacy of corticosteroid injection and surgical release. This study aimed to examine the incidence and length of the first extensor compartment septum.Forty sides of the wrists in 20 cadavers were used. The presence of a septum in the first extensor compartment was examined. The septum length was recorded with the radial styloid process as the reference point.The anatomical variations of the first extensor compartment were classified into 3 types...

Elongation of the styloid process occurs in 4-7% of individuals. In the majority this elongation is asymptomatic. Presence of oropharyngeal pain and dysphagia with such elongation is known as Eagle syndrome. The aetiology of Eagle syndrome is believed to be a reactive osseus hyperplasia of the styloid process in response to pharyngeal trauma or surgical intervention, such as tonsillectomy. We present a case of a 72-year-old lady with a twelve month history of left sided oropharyngeal pain and worsening dysphagia, presenting with a long, slender, bony intraoral projection found to be an elongated styloid process...

The removal of impacted mandibular third molar is associated with potential complications such as dry socket, paresthesia, uncontrolled socket bleeding, angle fracture, etc., which are commonly encountered in dental practice. This article presents a peculiar case of "ear bleed" concomitant with "isolated styloid" fracture following removal of impacted mandibular third molar, not reported in the literature till date. Ear bleed is a bothersome clinical sign that requires thorough investigation and prompt treatment because it is frequently related to fractures of the skull base...
