We describe a case of negative pressure pulmonary edema that occurred in the post-anesthesia care unit in a patient who had undergone transsphenoidal resection of a pituitary adenoma. Negative pressure pulmonary edema is an uncommon complication of general anesthesia. In this case, the patient's nasal cavity had been filled with surgical packs and she had not become accustomed to breathing thro...

Obstructive sleep apnea syndrome (OSAS) is a well-recognized disorder conventionally diagnosed with an elevated apnea-hypopnea index. Prolonged partial upper airway obstruction is a common phenotype of sleep-disordered breathing (SDB), which however is still largely underreported. The major reasons for this are that cyclic breathing pattern coupled with arousals and arterial oxyhemoglobin satur...

We report a case of a 45-year-old male with severe rhinoscleroma. The patient presented to the emergency room with dyspnea from a long-standing nasal-palatal mass. A tracheostomy was required for airway control. While dyspnea in the presence of an upper airway mass is typical of malignancy, consideration of non-oncological etiologies is important. We review the epidemiology, pathology, diagnosi...

Neuromuscular changes were studied by electromyography in rhesus monkeys which adapted to nasal obstruction for 2 years and then in the succeeding year recovered to nasal respiration. Obstructing the nasal passage with silicone plugs induced specific behavioral responses which remained for the duration of nasal obstruction and were lost within 8 days after removal of the plugs. Animals demonstr...

OBJECTIVE To determine the types and frequency of airway anomalies in patients with Pfeiffer syndrome. DESIGN Retrospective case series. SETTING Academic tertiary care pediatric hospital. PARTICIPANTS Eleven patients with Pfeiffer syndrome, 6 of whom were severely affected, were identified. All were included in the study. MAIN OUTCOME MEASURES Presence of tracheal anomalies, need for tr...

BACKGROUND Upper airway obstruction is a common complaint in children presenting to otolaryngology clinics. In such children, adenoid hypertrophy is often suspected. There are numerous ways to determine adenoid size, including palpation, mirror examination, endoscopic examination, lateral neck roentgenogram (X-ray), magnetic resonance imaging (MRI), and acoustic rhinometry. Pediatric patient co...

Obstruction in the upper airway can often cause reductions in breathing or gas exchange efficiency and lead to rest disorders such as sleep apnea. Imaging diagnosis of the obstruction region has been accomplished using computed tomography (CT) and magnetic resonance imaging (MRI). However CT requires the use of ionizing radiation, and MRI typically requires sedation of the patient to prevent mo...

OBJECTIVES To estimate the treatment effect of temperature-controlled radiofrequency (TCRF) reduction of turbinate hypertrophy in patients with sleep-disordered breathing (SDB) treated with nasal continuous positive airway pressure (CPAP), and to assess the impact of study design on this estimate. STUDY DESIGN Prospective, randomized, double-blind, placebo-controlled clinical pilot trial. M...

Objective: Aim of the study is to evaluate subjective outcomes and objective postoperatively investigate correlations between these measurements. Material Methods: This prospective before after surgical was conducted with patients admitted symptomatic nasal septum deviation (NSD) who underwent Cottle’s septoplasty. Morphometric diameters cavity were measured using a multi-detector computed tomo...
