The clinical and physiologic features of 28 infants with Pierre Robin syndrome and those of 20 infants with various types of nasal obstruction were reviewed to determine whether different causes of upper airway obstructure may lead to a common syndrome. The patients had no significant differences in distribution of main clinical manifestations. Their features included cyanosis with respiratory ...

INTRODUCTION Nasal valve collapse is a common cause of nasal airway obstruction. The valve area is commonly weakened secondary to rhinoplasty, aging, trauma, and other causes. The complexity of nasal valve repair techniques and its variable results combined with the fact that patients with valve collapse have often had previous surgery or are of advanced age are some of the reasons that this pr...

tracheobronchopathia osteochondroplastica (to) is a rare disorder of large airways with unknown etiology which is characterized by cartilaginous and bony nodules lining the mucosa of the trachea and major bronchi. generally, it is benign and asymptomatic, but it may present with cough, exertional dyspnea and wheezing. it could therefore be mistaken with asthma and chronic obstructive pulmonary ...

IMPORTANCE Nasal obstruction is common in children and difficult to quantify objectively. Symptom quantification is paramount for surgical and medical decision making. Acoustic rhinometry is a relatively new technique aimed at the objective assessment of nasal obstruction. There is no standardized method for the objective assessment of the pediatric nasal airway. OBJECTIVE To explore the corr...

The rational evaluation and management of nasal obstruction must be based on an understanding of the fundamental facts of nasal structure and function. The structure of the nasal airway is complex, because it is composed of markedly different regions. The support changes from soft t issue to carti lage to bone. The l ining changes from skin to mucosa. These structural components must be underst...

BACKGROUND Rhinitis and asthma share similar immunopathological features. Rhinomanometry is an important test used to assess nasal function and spirometry is an important tool used in asthmatic children. The degree to which the readouts of these tests are correlated has yet to be established. We sought to clarify the relationship between rhinomanometry measurements, fractional exhaled nitric ox...

OBJECTIVE To assess short- and long-term effects of rapid maxillary expansion (RME) on nasal flow in young children. Since RME has been reported to positively influence nasal obstruction in subjects with respiratory problems by reducing nasal resistance, a similar efficacy of RME could be expected in children with deciduous and/or mixed dentition who are affected by maxillary constriction and n...

Nasal obstruction is a complaint frequently encountered in otolaryngology. This obstruction can occur as a result of underlying inflammatory or anatomic pathologic conditions. Inflammatory pathologic conditions include allergic rhinitis, nasal polyposis, and chronic rhinosinusitis. Among the anatomic causes are septal deviation, turbinate hypertrophy, and nasal valve compromise (NVC). The nasal...
