OBJECTIVES/HYPOTHESIS Determine the impact of nasal obstruction on efficacy, success, and adherence of Provent therapy in patients with obstructive sleep apnea (OSA). STUDY DESIGN Prospective, two-arm, clinical pilot study at a single clinical site. METHODS Patients with OSA who failed continuous positive airway pressure therapy were divided into two treatment arms: arm 1 were patients with...

This article discusses the development and anatomy of the nasal septum and structures of the lateral nasal wall. Emphasis is placed on anatomic variations associated with surgically correctable nasal obstruction. Common variations, such as deviated nasal septum, inferior turbinate hypertrophy, paradoxic middle turbinate, and concha bullosa, are discussed. Rare developmental causes of nasal obst...

Objective. Nasal and upper respiratory tract obstruction in the neonatal period can result from a variety of conditions, and may present with variable symptoms. In the absence of dysmorphic features or other abnormalities, causes of nasal obstruction may be difficult to differentiate on initial examination. We report an unexpected and potentially life-threatening condition arising during the wo...

OBJECTIVE To determine the efficacy of a new surgical procedure to correct symptoms of nasal obstruction secondary to internal nasal valve narrowing. DESIGN Consecutive case series. SETTING Tertiary care multispecialty clinic. PATIENTS Patients with symptoms of nasal obstruction for at least 1 year, a closed but otherwise anatomically normal nasal valve, and resolution of symptoms with la...

Data from observational studies suggest that nasal obstruction contributes to the pathogenesis of snoring and obstructive sleep apnoea (OSA). To define more accurately the relationship between snoring, OSA and nasal obstruction, the current authors have summarised the literature on epidemiological and physiological studies, and performed a systematic review of randomised controlled trials in wh...

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...

background inferior turbinate hypertrophy (ith) is one of the common causes of nasal obstruction. in some case with ith due to allergic rhinitis medical therapy can be useful and in cases with refractory ith surgical techniques may be helpful. although there is no excellence [or superiority] among these surgical methods, radiofrequency (rf) has recently become popular. objectives this study com...

Nasal airway obstruction, a well-known cause of patient discomfort, is one of the most common presenting complaints to the otolaryngologist. The different causes of nasal airway obstruction are very wide-ranging, spanning from congenital life threatening causes to acquired benign causes. Herein, we present a case of nasal obstruction caused by widening of the posterior septum. A 52-year-old gen...

OBJECTIVES We wanted to evaluate whether the presence of nasal obstruction makes a change on the association between the modified Mallampati score and the severity of sleep-disordered breathing (SDB) and the sleep quality. METHODS Polysomnography (PSG), the modified Mallampati score (MMS), the body-mass index, and a questionnaire about nasal obstruction were acquired from 275 suspected SDB pa...
