Mouth breathing caused by nasal obstruction affects the normal growth and development of craniofacial structures, including changes in the orofacial muscles. Tongue muscles play an important role in patency of the pharyngeal airway, and changes in the breathing pattern may influence tongue function. The purpose of this study was to evaluate the effect of unilateral nasal obstruction during grow...

abstract acute upper airway obstruction (uao) is a life threatening complication that is well recognized after carotid endarterectomy, thyroidectomy and pharyngeal area intervention. it is not widely acknowledged that airway obstruction can occur after cervical spinal fusion surgery which was first described in 1955. there are a number of common postoperative problems which may become apparent ...

I t has been suggested that conditions associated with nasal obstruction predispose to the development of snoring and OSA (1,2). Some authors indicated that the nose accounts for approximately half of the total airway resistance to airflow (3). Nasal obstruction may contribute to an increase in snoring and sleep apnea frequency and severity (4). For this reason, nasal dilators have been propose...

OBJECTIVES To (1) quantify mucosal cooling (ie, heat loss) spatially in the nasal passages of nasal airway obstruction (NAO) patients before and after surgery using computational fluid dynamics (CFD) and (2) correlate mucosal cooling with patient-reported symptoms, as measured by the Nasal Obstruction Symptom Evaluation (NOSE) and a visual analog scale (VAS) for sensation of nasal airflow. ST...

The importance of nasal airflow resistance in the pathogenesis of obstructive sleep apnea syndrome (OSAS) remains contentious. We performed formal nocturnal polysomnography (PSG) on OSAS patients under conditions of baseline and reduced nasal resistance to answer two main questions. First, to what degree does baseline nasal airflow resistance influence upper airway collapse in OSAS patients? Se...

developmental midline perinasal masses in children are rare lesions specifically in association with choristomas. we encountered a 3-year-old boy with epiphora, a striking mass on the nasal bridge and ipsilateral nasal hypoplasia. ct scan imaging showed multiple calcified areas within the tumor in addition to linear defect in frontal bone, hypoplastic left ethmoidal sinus and left nasal cavity,...

Vestibular stenosis is an uncommon but debilitating cause of nasal obstruction leading to serious impairment airway. It caused by granulation and fibrosis vestibular lining there circumferential scar retraction in the inlet cavities. Stenosis may be congenital or acquired. Causes acquired include burns, trauma, infections, iatrogenic insult vestibule. Surgical correction usually done excision f...
