INTRODUCTION To provide clinical information and diagnosis in mouth breathers with transverse maxillary deficiency with posterior crossbite, numerous exams can be performed; however, the correlation among these exams remains unclear. OBJECTIVE To evaluate the correlation between acoustic rhinometry, computed rhinomanometry, and cone-beam computed tomography in mouth breathers with transverse ...

Thirty-four children with clinically and radiologically confirmed adenoid hypertrophy underwent otoscopy, impedance tests, active anterior rhinomanometry and nasal mucociliary clearance evaluation before and 6 months after adenoidectomy. Mucociliary clearance velocity increased significantly while binasal resistances decreased after surgery. The authors conclude that mucociliary evaluation and ...

The effect of aspirin on nasal resistance to airflow was investigated by rhinomanometry in 25 healthy subjects before and after ingestion of aspirin or vitamin C in a double blind crossover trial. Aspirin caused a significant increase in nasal resistance compared with vitamin C. The effect of aspirin may be due to its inhibition of the synthesis of prostaglandins.

background nasal valve collapse and especially internal nasal valve insufficiency is a common cause of nasal airway obstruction. this study compares the effects of spreader graft and overlapping lateral crural technique on rhinoplasty by rhinomanometry. methods fifty patients were randomly assigned into two groups and underwent spreader graft or overlapping lateral crural technique. objective a...

abstract:   background: the most important and complex phenomenon of respiratory function of the nose is related to different nasal anatomy. the differences in facial anatomic structure between different races may also be reflected in nasal resistance and airflow. caucasians has different facial anatomic structure which is the reflection of intranasal resistance or consequence of airflow. the a...
