Laryngeal tumors are uncommon in children, accounting only for 2% of the laryngeal anomalies. Ninety-eight percent are benign; the most frequent ones are recurrent respiratory papillomatosis and haemangioma. Granular cell tumor, also called Abrikossoff tumor, is an unusual benign neoplasm, especially in the larynx. Clinical manifestations depend on the size and location of the tumor. Dysphonia is the main presenting symptom. The diagnosis is confirmed by the biopsy. The treatment of choice is surgery. We present a 9-year-old girl with dysphonia and exertion dyspnea due to a granular cell tumor of the larynx, and we emphasize the importance of considering the endoscopic evaluation of the airway in every child with progressive or persistent dysphonia in order to determine the etiology...

Snoring is a sleep phenomenon due to the partial upper airway obstruction during sleep which causes vibration of the tissues of the rhino-oro-hypopharynx and less frequently the larynx. This study evaluated the use and effectiveness of the erbium:YAG 2940-nm laser as an adjunctive in providing treatment for patients suffering from chronic snoring-related sleep disorders. A prospective study of 40 consecutive patients with snoring and sleep disorders was performed, assessing data before and after three Er:YAG laser treatment sessions...

The major complications of paediatric airway management are uncommon, but the outcomes are often severe. Over the last decade, additions and advancements in the devices and technology have significantly improved our ability to manage difficult paediatric airways safely. Videolaryngoscopy involves the use of video and optical technology to facilitate indirect visualisation of the larynx during intubation and has been seen as an evolutionary step in intubation technology. Over the past few years, video laryngoscopes have been receiving plenty of attention as new airway devices for use in paediatric patients...

INTRODUCTION: During the aging process, natural modifications occur in the larynx and the structures involved in phonation which explain the specific characteristics found in the voices of elderly persons. When, at any moment, a voice fails and there is interference with communication, a voice disorder has occurred. This can generate disadvantages in communicative efficiency and have a negative impact on quality of life, compromising mechanisms of socialization, the maintenance of autonomy, and the sense of well-being...

Tuberculosis (TB) of the head and neck region is quite common in endemic countries, but is still misdiagnosed due to its varied presentation and different sites of involvement. The aims of the present study were to present the diversities of presentation of head and neck tuberculosis with the diagnostic predicaments faced during evaluation and to assess treatment response to anti-tubercular treatment (ATT). We analysed 48 patients with head and neck tuberculosis who presented to the Department of Otorhinolaryngology in our tertiary care urban hospital over a period of two years from 2013 to 2015 and recorded their data, which included presenting complaints, local and systemic examination findings, investigation results and treatment outcomes...

Laryngopharyngeal reflux (LPR) is a common defect among laryngological and phoniatric patients. Although LPR is categorized as a superficial gastroesophageal reflux disease (GERD), differential diagnosis should treat these two diseases separately. LPR symptoms can be assessed in the interview using as a tool the reflux symptom index (RSI). In addition, changes in the larynx that occur during LPR might be seen during laryngoscopy and classified according to the reflux finding score (RFS). One of the main mucosal irritants in LPR is pepsin which digests proteins and impairs the functions of the upper respiratory tract cells by affecting carbonate anhydrase (CAIII) and the Sep 70 protein...

OBJECTIVES/HYPOTHESIS: Young professional singers can easily reach very high pitches. In contrast, older singers often complain that they have to exert substantially more laryngopharyngeal force to reach the same high pitch compared with their earlier years. Various factors such as the property changes of the mucosa and ossification that impact the singing apparatus were suggested as explanations in the literature. The aim of this study was to analyze thyroid deformation-and thereby stiffness indirectly-during singing as a potential reason for this phenomenon...

Tuberculosis (TB) is an infectious disease and major health concern. Head and neck tuberculosis (HNTB) is relatively rare, but can arise in many regions, including the lymph nodes, larynx, oral cavity and pharynx. We retrospectively reviewed the clinical records of 60 patients diagnosed with HNTB in our department between March 2005 and January 2016. A review and summary of previous HNTB articles published in PubMed since 1885 was also performed. The subjects consisted of 17 males and 43 females, and the average age of patients was 45 ± 14...

The larynx sometimes requires repair and reconstruction due to cancer resection, trauma, stenosis, or developmental disruptions. Bioengineering has provided some scaffolding materials and initial attempts at tissue engineering, especially of the trachea, have been made. The critical issues of providing protection, maintaining a patent airway, and controlling swallowing and phonation, require that the regenerated laryngotracheal cartilages must have mechanical and material properties that closely mimic native tissue...

INTRODUCTION: "Bolus death" or "Café Coronary syndrome" refers to death due to asphyxia caused by an occlusion of the upper airways due to food. In this kind of asphyxia, the food bolus obstructs the larynx or the bronchial branches. This kind of event often affects subjects with acute intoxication due to alcohol or drugs, or with edentulism and with neurological or psychiatric diseases. CASE REPORT: An elderly woman, suffering from schizophrenia, was found dead in her house due to food bolus asphyxia...

The distributions of β-defensin 1 and 2 in secretory host defense system throughout respiratory tract of healthy rats were immunohistochemically investigated. In the nasal epithelium, a large number of non-ciliated and non-microvillous cells (NCs) were immunopositive for both β-defensin 1 and 2, whereas a small number of goblet cells (GCs) were immunopositive only for β-defensin 1. Beta-defensin 2-immunopositive GCs were few. In the nasal glands, a small number of acinar cells and a large number of ductal epithelial cells were immunopositive for both β-defensins...

The presence of liquid near the larynx of immature mammals triggers prolonged apneas with significant O2 desaturations and bradycardias. When excessive, this reflex (the laryngeal chemoreflex; LCR) can be fatal. Our understanding of the origins of abnormal LCR are limited; however, perinatal stress and male sex are risk factors for cardio-respiratory failure in infants. Because exposure to stress during early life has deleterious and sex-specific consequences on brain development it is plausible that respiratory reflexes are vulnerable to neuroendocrine dysfunction...

Laryngeal squamous cell carcinoma (LSCC) is a genomically complex disease that is difficult to target, and efforts have been made to identify new treatment strategies and   molecular markers that might stratify patients and individualize options for treatment. miR-373 has diametrically opposed roles in different stages and types of cancers. miR-373 has been suggested to quantitatively control E-cadherin and CD44 expression. We studied the expression of miR-373, E-cadherin and CD44 in laryngeal squamous cell carcinoma and evaluated the association between the disease and clinical characteristics of patients...
