His Master's thesis was about neuronal injury and astrogliosis. This case study reports a rare variation of the superior laryngeal artery (SLA), which is the principal arterial supply of the larynx. The knowledge of the arterial variations is essential for the surgeons to prevent blood loss and postoperative complications. During routine dissection of an adult male cadaver, a rare arterial vari...
To the Editor: We read with interest the article by Hillerman et al.1 concerning laryngeal nerve identification during thyroid surgery using the laryngeal mask airway (LMA). Although postoperative voice changes are usually attributed to recurrent laryngeal nerve injury, the external branch of the superior laryngeal nerve (EBSLN) is also at risk since it runs close to the superior thyroid artery...
isolated dissection of the superior mesenteric artery is a rare occurrence with a hitherto unknown exact etiology. patients may present with abdominal symptoms or hemodynamic instability. w e herein present a case of spontaneous isolated superior mesenteric artery dissection in a 48-year-old man, who was admitted with epigastric pain. due to an undiagnosed paced rhythm on the electrocardiogram,...
OBJECTIVE We evaluated the contribution of intraoperative neuromonitoring to the visual and functional identification of the external branch of the superior laryngeal nerve. MATERIAL AND METHODS The prospectively collected data of patients who underwent thyroid surgery with intraoperative neuromonitoring for external branch of the superior laryngeal nerve exploration were assessed retrospecti...
The external carotid arterial system is a complex vascular system constituting the nourishment to territorial areas of the head, face and neck tissues. Though the variation in the carotid arteries and their branches are common in the carotid triangle, it is important for the clinicians, surgeons and the radiologists to be aware of all possible variations of these arteries. This paper is an ende...
OBJECTIVES/HYPOTHESIS To enhance understanding of spontaneous laryngeal muscle reinnervation following severe recurrent laryngeal nerve injury by testing the hypotheses that 1) nerve fibers responsible for thyroarytenoid muscle reinnervation can originate from multiple sources and 2) superior laryngeal nerve is a source of reinnervation. STUDY DESIGN Prospective, controlled, animal model. M...
Effects of asymmetric superior laryngeal nerve stimulation on glottic posture, acoustics, vibration.
OBJECTIVES/HYPOTHESIS Evaluate the effects of asymmetric superior laryngeal nerve stimulation on the vibratory phase, laryngeal posture, and acoustics. STUDY DESIGN Basic science study using an in vivo canine model. METHODS The superior laryngeal nerves were symmetrically and asymmetrically stimulated over eight activation levels to mimic laryngeal asymmetries representing various levels of...
THE CERVICAL BRANCHES OF THE VAGUS NERVE THAT ARE PERTINENT TO ENDOCRINE SURGERY ARE THE SUPERIOR AND THE INFERIOR LARYNGEAL NERVES: their anatomical course in the neck places them at risk during thyroid surgery. The external branch of the superior laryngeal nerve (EB) is at risk during thyroid surgery because of its close anatomical relationship with the superior thyroid vessels and the superi...
conclusions in addition to an appropriate clinical history, ct findings indicating decreased aortomesenteric angle and a shortened aortomesenteric distance can suggest the diagnosis for both the superior mesenteric artery syndrome and accompanying nutcracker syndrome. case presentation in this report, a patient is described presenting with epigastric pain and weight loss due to superior mesente...
OBJECTIVE To determine the differences in myelination between the human recurrent laryngeal nerve and superior laryngeal nerve. METHODS Fifteen confirmed laryngeal nerve specimens were harvested from five cadavers. Cross-sections were examined under a photomicroscope and morphometric analysis performed. RESULTS There was a significantly greater number of myelinated fibres than unmyelinated ...
