Laryngeal granulomas are benign lesions located in the posterior third of the glottis, mainly at the level of the vocal apophysis of the arytenoid cartilage. They are typically associated with three etiological factors: endotracheal intubation, inappropriate voice use and/or gastroesophageal reflux. The formation of a post-intubation laryngeal granuloma is a late complication related to intubat...

UNLABELLED Vocal cord paralysis (VCP) can be caused by any process that interferes with the normal function of the vagal nerves or recurrent laryngeal nerves. It may be a first sign of extensive and severe pathology. Radiologists must therefore be able to recognise the imaging findings of VCP and know the course of the vagal and recurrent laryngeal nerves. This review focuses on the anatomy and...

We previously reported that the activation of water-responsive afferents in the superior laryngeal nerve was responsible for the inhibition of gastric motility. The present study was undertaken to clarify the roles of the vagal preganglionic neurons responsible for laryngeal afferent-mediated inhibition of gastric motility. Intravenous injection of atropine abolished the inhibition of motility ...

Laryngeal cancer is a rare type of neoplasia, constituting approximately 2% of all human cancers. Mutations of the ras gene family is one of the main activating mechanisms in human cancer. Their involvement in head and neck cancer has been mainly demonstrated at the level of the overexpression whereas ras mutations in these cancers are rare in the Western world. In the present study we explored...

Squamous cell carcinoma (SCC) of the larynx is extremely rare in adolescents and typically has an aggressive nature. The mechanism of laryngeal oncogenesis is complex and little is known about the role that human papillomavirus (HPV) plays in SCC in adolescents. We report a case of invasive laryngeal SCC that co-expressed HPV DNA subtypes 16 and 18 in a 13 year-old boy. Detection of HPV DNA typ...

In this study, our aim was to investigate the prognostic features of the thymidine labeling index (TLI) in laryngeal squamous cell carcinoma (SCC). The TLI values in tumor tissues and adjacent healthy tissues were assessed in 40 patients who had a pathological diagnosis of laryngeal SCC. The data were correlated with age, pTNM, histological grade and recurrence. The tissues (tumor and adjacent ...

Localized laryngeal amyloidosis is a rare disease with poorly understood aetiology. The commonest symptom at presentation is dysphonia and for a correct diagnosis of amyloidosis to be made a high index of suspicion is needed [Fraihat A, Ardah A. Laryngeal amyloidosis: a case report. J R Med Serv 2005;17:57-9; Passerotti GH, Caniello M, Hachiya A, Santoro PP, Imamura R, Tsuji DH. Multiple sited ...

OBJECTIVE To determine if selective reinnervation of the cricothyroid muscle could be achieved with muscle-nerve-muscle neurotization. DESIGN Case series. SETTING Tertiary referral center. PATIENTS Three consecutive patients with high vagal lesions that resulted in unilateral laryngeal paralysis. INTERVENTIONS Patients underwent laryngeal reinnervation with ansa hypoglossi to recurrent ...

The aim of partial laryngeal surgery is to perform a radical removal of cancer, reconstructing the anatomical crossing of the respiratory and digestive tracts with preservation of laryngeal function. [1-5] Despite usual favorable results, postoperative functional impairment may persist. In such cases, dysphagia and dyspnea are the most important complications and may cause recurrent aspiration ...
