Introduction: Laryngeal burns cause long-term voice disorders due to mucosal changes of the vocal folds. Inhalation injuries affect voice production and result in changes in the mucosal thickness and voice quality.   Case Report: A 47-year-old woman was transferred to our department with laryngeal burns sustained during a house fire. On laryngoscopic examination, mucosal waves of both vocal fol...

balloon dilatation of stricture is one of the new treatment methods among patients with gastric outlet obstruction (goo). however, the prevalence and underlying etiologies of goo in various populations are different. the goal of the present study was to determine the effectiveness of endoscopic balloon dilatation and factors that would affect its success rate patients with benign etiology for g...

The glottal open quotient (OQ) is often associated with the amplitude of the first source harmonic relative to the second (H1*H2*), which is assumed to be one cause of a change in vocal quality along a breathy-to-pressed continuum. The association between OQ and H1*-H2* was investigated in a group of 5 human subjects and also in a computational voice production simulation. The simulation incorp...

Patients with primary head and neck cancers have a higher risk of developing esophageal cancer. The aim of this study was to investigate esophageal cancer prevalence, its risk factors (ethanol and tobacco consumption) and dietary habits in patients with head and neck cancer. Three hundred and twenty-six adults with primary head and neck cancer were followed by a retrospective observational stud...

Studies of speech source-filter interaction usually investigate the effect of the speech transfer function (loading) on vocal fold vibration and the voice source. In this study we explore how vocal fold mechanics affect the transfer function throughout the glottal cycle, with emphasis on the closed phase. Coupling between the subglottal and supraglottal airways is modulated by the laryngeal imp...

OBJECTIVE To determine the interrater reliability of drug-induced sleep endoscopy (DISE). DESIGN Prospective cohort; blinded comparison. SETTING Academic referral center. PARTICIPANTS Subjects with obstructive sleep apnea unable to tolerate positive airway pressure therapy. INTERVENTIONS Drug-induced sleep endoscopy was performed with intravenous propofol infusion to achieve sedation, a...

Two auxiliary methods of diagnosing nasopharyngeal airway obstruction were compared. Cephalometric radiography and nasopharyngeal videoendoscopy were evaluated for efficacy in terms of reproducibility and validity. Thirty orthodontic patients (7 to 12 years of age) seeking otorhinolaryngologic treatment for mouth breathing, or mouth and nose breathing, had nasopharyngeal endoscopy and radiograp...

AIM Fungal rhinosinusitis in patients with chronic sinusal disease study. In the past decades, there has been an increase in fungal infections, and fungal rhinosinusitis (FRS) has been diagnosed more frequently. Knowing the fungal flora, its prevalence and symptomatic presentation in patients with chronic rhinosinusitis (CRS) will allow a better understanding of this disease, permitting a corre...

The high quality of a euphonic voice is the result of complex interactions between many organs and systems. Vibrating vocal folds play a crucial role in this process. Their physiological motion is conditioned by the presence of the layered structure of laryngeal mucosa. In this study, we assessed the degree of dysphonia according to the Union of European Phoniatrics (UEP) scale. Videoendoscopy ...

The relative magnitude of the first two harmonics of the voice source (H1*-H2*) is an important measure and is assumed to be one exponent of changes in vocal quality along a breathyto-pressed continuum. H1*-H2* is often associated with glottal open quotient (OQ) and glottal pulse skewness (as quantified by speed quotient, SQ), but may also covary with fundamental frequency (F0) and vocal intens...
