paragangliomas in the head and neck are found typically in the region of the carotid body, jugular body, and along the 9th and 10th cranial nerves. they can occur in multicenteric forms, but generally, laryngeal paragangliomas are not found in these patients. only two cases of laryngeal paraganglioma have been reported with a synchronous lesion elsewhere. we report an additional case of a 34-ye...

We report a case of laryngeal tuberculosis in a 47-year-old Korean man. Laryngeal tuberculosis is rare and currently accounts for less than 1% of all cases of tuberculosis. Clinical features of laryngeal tuberculosis include hoarseness, odynophagia and dyspnoea. Macroscopically, laryngeal tuberculosis may mimic laryngeal carcinoma, chronic laryngitis or laryngeal candidiasis. The diagnosis is o...

the aim of this study is to determine whether there is a role of podoplanin and glutathione s-transferases t1 (gst-t1) expression in laryngeal squamous cell carcinoma. the study was completed with 33 patients and gene expression analysis was performed by qrt–pcr. the podoplanin and gst-t1 expression patterns were analyzed to determine their correlation with clinicopathologic parameters of laryn...

A nonrecurrent laryngeal nerve variant of the inferior laryngeal nerve is very rarely seen, and surgeons should keep it in mind during thyroid surgery. Preoperative findings, like situs invertus and dysphagia lusoria, may be suggestive of a nonrecurrent laryngeal nerve. However, these findings always have not to be together with nonrecurrent laryngeal nerve, like our case.

laryngeal leiomysarcoma is an extremely rare malignancy originating from smooth muscle cells. its rarity is due to the fact that only less than 50 cases of pure laryngeal leiomyosarcoma and less than 10 cases of hypopharyngeal leiomyosarcaoma have been reported in modern medical literature.  even though the clinical presentation mimics that of a laryngeal carcinoma forming the major bulk of the...

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 ...

Pulmonary sequestration (PS) and pneumomediastinum are two rare clinical diseases. Pneumomediastinum was generally observed in infants either with diseased lungs or who were performed assisted ventilation or resuscitation following birth. It was reported in patients with existing ectopic thoracic kidney and laryngeal cysts however, no coexisting congenital lung anomalies were reported. Here, we...

Introduction hyroid gland receives more blood per gram of tissue (5.5 ml/gm/min) than any other organ. 1 All blood is supplied by a number of arteries and drained by an even greater number of veins. Recurrent laryngeal nerve is intimately related with thyroid gland especially with inferior thyroid arteries. The diseases which usually affect the thyroid gland are hypothyroidism, hyperthyroidism,...

Laryngeal tuberculosis is the most common granulomatous disease of the larynx. In this study, the videostroboscopic findings and vocal assessments of a 28-year-old female with laryngeal and pulmonary tuberculosis were evaluated. Although it can be treated successfully, tuberculosis of the larynx may cause irreversible changes in voice quality which is very important for vocal professionals.
