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...

Otolaryngologists are being asked with increasing frequency to assess adequacy of the upper airway and to treat upper airway obstructive problems in orthodontic patients. The incentive has been provided by recent studies that purport to relate upper airway obstruction to dental and craniomorphologic changes. It is hypothesized that prolonged oral respiration during critical growth periods in ch...

Reinforced tubes are commonly used to minimize the opportunity of upper airway obstruction in patients at risk. There are a few reports of the airway obstruction resulted from kinked reinforced tubes. This report describes the obstruction of a reinforced tube in an adult patient who underwent tonsillectomy. Under general anesthesia; an armoured endotracheal tube was inserted into the trachea un...

Snoring and obstructive sleep apnoea (OSA) both exhibit multilevel upper airway obstruction. The Importance of evaluating the dynamics of the obstructing upper airway cannot be emphasised enough. Accurate assessment and evaluation of the upper airway could potentially lead to improved surgical and non-surgical treatment outcomes. Most of these patients would have undergone an ambulatory sleep s...

There are a number of studies in the literature, that associate nasopharyngeal airway obstruction, as a result of adenoid enlargement, to the development of skeletal and dental abnormalities. However, the etiologic role of hypertrophied adenoids and tonsils in developing an aberrant dentofacial growth is not clear, yet. The present investigation attempted to study the incidence of maxillary pos...

918 Pharyngeal Muscles during Sleep (Strohl, Olson) W hile it is known that neural activation of pharyngeal muscle exhibits respiratory periodicity and is an integral part of the respiratory control system,’ the mechanical consequences of neuromuscular activity in upper airway muscles are not well understood. Clinical and physiologic studies of Remmers et al,2 Brouillete and Thach,3 and others4...
