introduction: laryngeal dysfunction may be divided into three categories; organic, neurologic and functional disorders. dysphonia and hoarseness are the most common symptoms and, in some cases, the only signs of laryngeal dysfunction. in differential diagnosis of any type of chronic hoarseness, a neoplastic process must be considered and, thus continuous light video laryngoscopy can provide imp...

Abstract Background Major neck surgery is done typically under general anesthesia (GA). The neural blocks of the include blocking cervical plexus, superior laryngeal nerve, trans-laryngeal, block glossopharyngeal and local anesthetic infiltration. In patients with a high risk GA, including those pulmonary dysfunction, prior myocardial ischemia or infarction, regional mainly indicated. Case pres...

Introduction: The major presenting symptom of nasal polyps is nasal obstruction. The role of nasal obstruction in the genesis of laryngeal disorders is still unknown.   Materials and Methods: The aim of this study was to evaluate laryngeal videostroboscopic changes after functional endoscopic sinus surgery (FESS) in patients with nasal polyposis. A longitudinal study was carried out from M...

Carbon dioxide (CO2) laser surgery as a conservative tool plays a peculiar role in the management of head and neck cancer. Numerous patients who were candidates for transoral laryngeal microsurgery have forced us to eliminate frozen-section evaluation of surgical margins and use a magnified view of the larynx. The present study evaluated surgeon-judged negative margins with permanent microscopi...

PURPOSE The aim of the study was to assess the usefulness of intraoperative neuromonitoring (IONM) in identifying anatomical variants of the recurrent laryngeal nerve (RLN) during thyroidectomies, with emphasis on the nerve's relationship to the inferior thyroid artery (ITA), Zuckerkandl's tubercle, nonrecurrent laryngeal nerves (NRLNs), and extralaryngeal bifurcation. METHODS A total of 128 ...

The present investigation was designed to examine the effect of change in vocal fold mass and stiffness on vocal fold vibration. To do this, the effect of variation in superior laryngeal nerve stimulation (SLNS) and recurrent laryngeal nerve stimulation (RLNS) was studied Photoglottography (PGG), electroglottography (EGG), and subglottic pressure (Psub) were measured in seven mongrel dogs using...

Extranodal lesions may be the sole manifestation of Rosai-Dorfman disease (RDD). Although the head and neck region is one of the most common extranodal sites, laryngeal involvement is very rare. A 44-year-old woman presented with a complaint of progressive dyspnea. She had a three-year history of treatment for asthma and a history of operation for a nasal mass that afflicted her for 15 years an...

BACKGROUND To investigate the diagnostic value of dynamic magnetic resonance imaging (MRI) and positron emission tomography/computed tomography (PET/CT) for laryngeal cancers after inadequate CT results. MATERIAL/METHODS The study comprised 45 patients investigated for primary laryngeal cancer or recurrence-residue in which CT was considered inadequate. A mass was found in 20 patients. Dynami...
