BACKGROUND Formulas based on age and height often fail to reliably predict the proper endotracheal tube (ETT) size in pediatric patients. We, thus, tested the hypothesis that subglottic diameter, as determined by ultrasonography, better predicts optimal ETT size than existing methods. METHODS A total of 192 patients, aged 1 month to 6 yr, who were scheduled for surgery and undergoing general ...

A method for quantitative measurement of gas volume changes in upper airway is presented in this paper. The aim of this study is to assess the feasibility of a novel Cone Beam Computerized Tomography (CBCT) technique for quantitative measurement of gas volume in upper airway. Our application is defining and tracking minute volume changes (a few milliliters) of airways caused by surgery, such as...

OBJECTIVE To describe the results of an outcome survey of 18 cases of pediatric lymphangioma with dyspnea from encroachment on the tongue base, parapharyngeal space, and/or larynx. DESIGN Retrospective review of files from January 1983 to September 1998. SETTING Pediatric otolaryngology departments from 2 referral centers. PATIENTS Eighteen patients were treated. The average age at initia...

The past decade has seen several innovations in the surgical techniques available for treatment of patients with sleep-disordered breathing. Outpatient techniques such as laser-assisted uvulopalatoplasty (LAUP) and more aggressive procedures designed to address hypopharyngeal and base of tongue obstruction (genioglossus advancement and hyoid myotomy) have been developed and proven successful. W...

INTRODUCTION the evolution of snoring and OSAS in children is not well established since few studies of patients without surgical treatment have been published. OBJECTIVE to evaluate the evolution of sleep disordered breathing in children who had not been submitted to upper airway surgery. METHOD twenty-six children with snoring who had not undergone upper airway surgery were evaluated pros...

Background: ETT is important in securing paediatric airway and its right size plays crucial role patients. The anatomy patients different from adults hence requires precise size. subglottic diameter being the narrowest portion of upper airway, determines USG safe, reliable, non-invasive tool used to estimate correct Conventional formulae included age height. Concerns prone position include acci...

The aim of the present retrospective study was to evaluate the influence of age and gender on upper and lower airway width and upper lip length. In this study, 390 lateral cephalograms were divided into 13 age groups (ranging from 6 to 18 years) and were analyzed. The intergroup differences were analyzed using a MANOVA (Multivariate Analysis of the Variance), and the intragroup differences were...

Cyclo-oxygenase is the rate-limiting enzyme in the prostanoid pathway. Although expression of the inducible isoform of cyclo-oxygenase (COX-2) is associated with cytokine-mediated inflammation, recent evidence suggests a homeostatic role for epithelial COX-2 in the gastrointestinal tract. The aim of this study was to examine the expression and localization of COX-2 in human airway epithelium bo...
