We describe a case of isolated physeal fracture of ulna distal end in a 13-year-old boy. This fracture type is uncommon, especially Salter-Harris type III of this injury has not been reported. Plain radiographs showed a small vertical fracture line at the ulnar distal end and an enlargement of epiphyseal plate at the base of ulnar styloid process. The present case was successfully managed with conservative treatment because of its minimal displacement.

Eagle Syndrome can present with a variety of symptoms and be caused by an elongated styloid process or calcified stylohyoid ligament. Patients failing medical management of this disorder may be treated with surgical excision of the styloid process. In the literature, transoral and transcervical approach have both been described. Although transoral approaches typically begin with a tonsillectomy, tonsil-sparing approaches have also been utilized. With the advent of robotic surgery, the potential for a tonsillectomy sparing approach has become a feasible alternative, preventing the pain and morbidity associated with adult tonsillectomy while continuing to provide superior exposure and instrumentation...

Abnormal elongation of styloid process (Eagle syndrome) may cause compression of the adjacent structures in the neck, the most important of which is the carotid artery. This condition may cause damage to the wall of carotid artery and result in cerebrovascular ischemic event. Bilateral carotid artery damage and cerebral stroke because of overgrown styloid processes at both sides is a rare condition. In this article, we report a case of bilateral ischemic stroke because of carotid compression by elongated styloid process at both sides treated by surgical resection of both processes...

Eagle's syndrome is characterised by focal pain in the tonsillar fossa on wide mouth opening or head rotation and various accompanying symptoms. While the syndrome is difficult to diagnose, shortening the styloid process via a transoral or transcervical surgical approach has been shown to be the most effective treatment. The aim of this article was to document our experience with a transoral robotic approach to treat Eagle's syndrome and to present the outcomes of four patients. We reviewed the cases of four patients with Eagle's syndrome who underwent transoral robotic surgery (TORS)...

BACKGROUND: Elongated styloid process syndrome (Eagle's syndrome) is the term given to the symptomatic elongation of the styloid process or the mineralization of the stylohyoid or stylomandibular ligament. The two commonly used approaches for the surgical treatment of this syndrome are the transcervical and transoral approaches. Both have their limitations and specific intraoperative risks. Here, we report the treatment of a patient with Eagle's syndrome using the transoral approach in conjunction with piezoelectric surgery, surgical planning, and intraoperative navigation to reduce the risk of complications...

The aim of this study was to analyse lunate fractures and any associated osseo-ligamentous injuries. A systematic review identified 34 cases. We identified carpal instabilities at the radiocarpal and midcarpal joints in volar and dorsal directions. Radiocarpal instabilities (10/34) were usually dorsoradial (8/10), with a transverse lunate fracture, best seen on a coronal image. Midcarpal instabilities (24/34) were usually volar (14/18), with a volar lunate shear fracture, best seen on a sagittal image. Instabilities were sub-classified into non-displaced, subluxated and dislocated...

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)...

PURPOSE: The purpose of this study was to investigate the morphology and calcification pattern of the styloid process (SP) and to determine their relations with subjects' age, gender, and dental status. MATERIALS AND METHODS: 910 panoramic radiographs were stratified by age, dental status and gender. The distance between the points where SP leaves the tympanic plate of the temporal bone and the bony tip of SP was measured. Calcification patterns were classified as : (A) Region 1, tympanohyal alone (B) Region 2, stylohyal alone (C) Region 1 and 2, separate (D) Regions 1 and 2, continuous (E) Regions 1, 2, and 3, continuous (F) Regions 1, 2, and 3, separate (G) Regions 1 and 2, continuous, but separate from 3 (H) Regions 2 and 3, separate (I) Regions 2 and 3, continuous, but separate from 1 (J) Region 3 alone (K) Region 3 and 4, continuous (may include calcification in one other region) (L) No styloid process visible...

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.
