DESCRIPTION A full-term male neonate was born by vaginal delivery developed respiratory distress, noisy breathing and central cyanosis shortly after birth. He required intubation with a low setting of conventional ventilation, and his respiratory status dramatically improved. A 5 French catheter was passed nasally with difficulty bilaterally. CT scans of the nasal cavity revealed a marked narro...

Figure 1. An old photograph before developing the nasal deformity (left); recent preoperative photograph (right). DESCRIPTION A 55-year-old man comes to the office for consultation regarding a gradually enlarging lesion on his nose, and nasal airway obstruction. This has developed over several years. Physical examination shows enlargement of the nose, pitting and scarring of the skin, and sever...

OBJECTIVES To develop a method to quantify nasal tissue resilience, to establish the normal range for persons without nasal obstruction, and to measure the changes in tissue resilience resulting from standard open rhinoplastic techniques. METHODS A new device is described that determines nasal tissue resilience. Measurements on the nasal tip were obtained in triplicate at 5 distinct anatomica...

IMPORTANCE Clinical management of nasal airway obstruction (NAO) in patients with and without nasal allergic symptoms and nasal valve collapse (NVC). OBJECTIVE To examine the impact that autologous alar batten grafts have on patients with NAO owing to NVC and their affect on nasal steroid use and allergic symptoms. DESIGN A prospective study. SETTING Indiana University Medical Center, Ind...

BODY: Introduction: Obstructive sleep apnea (OSA) is a common sleep disorder affecting both men and women in all ethnicities. It is well known that the primary cause of OSA is upper airway obstruction due to either anatomical or neurologic factors. The primary treatment modality for OSA is Continuous Positive Airway Pressure (CPAP). However, a significant proportion of patients diagnosed with O...

BACKGROUND The efficiency of nasal surgeries can be determined by objective or subjective methods. We have assessed the effect of nasal obstruction after different nasal surgeries using Acoustic Rhinometry (AR) and Nasal Obstruction Symptom Evaluation (NOSE) Scale. METHODS Between May 2011 and May 2012, 40 young adult patients and 10 healthy volunteers as control group who referred to ...

Our study was to assess whether there were differential effects of nasal continuous positive airway pressure (nCPAP) on different kinds of obstruction in either upper or lower airways in patients with chronic obstructive pulmonary disease (COPD). nCPAP (6 cmH2O for ten minutes) was applied to 7 patients with reversible extrathoracic upper airway obstruction (RUAO) and 3 patients with fixed extr...

Previous studies of different samples have demonstrated associations between craniocervical angulation and craniofacial morphology, between airway obstruction by adenoids and craniofacial morphology, and between airway obstruction and craniocervical angulation. A hypothesis to account for the different sets of associations was suggested by Solow and Kreiborg in 1977. In the present study, the t...

IMPORTANCE The internal nasal valve is the narrowest part of the nasal airway and a common site of inspiratory collapse and obstruction of nasal airflow. Over-the-counter mechanical nasal dilators are an alternative to surgical intervention that attempts to improve airflow through the internal nasal valve. OBJECTIVE To determine the efficacy of over-the-counter mechanical nasal dilators and c...

RATIONALE Obstructive sleep apnea syndrome is due to upper airway obstruction and is associated with increased morbidity. Although continuous positive airway pressure efficaciously treats obstructive apneas and hypopneas, treatment is impeded by low adherence rates. OBJECTIVES To assess the efficacy on obstructive sleep apnea of a minimally intrusive method for delivering warm and humidified ...
