Background: Nasal obstruction is a common problem in patients with obstructive sleep apnea (OSA). Systematic evaluation of nasal obstruction remains challenging due to the high number of variables and factors that contribute to nasal obstruction. Nasal examination by means of anterior rhinoscopy is limited to the evaluation of anterior septal deviation, internal nasal valve angle, and inferior ...

BACKGROUND Turbinate hypertrophy is one of the common causes of chronic nasal obstruction. In principle, therapeutic guidelines recommend medical treatment. Failure to treat turbinate thickening despite drug therapy may indicate the need for surgery. The main aim of this study was to determine the effect of radiofrequency surgery, among various other surgical procedures, on people with both nas...

introduction: nasal polyps are benign prolapsed mucosal lesions which commonly arise from the paranasal sinuses and lateral walls of the nose especially the contact areas of osteomeatal complex. though nasal polyps arising from the nasal septum have been reported, those arising from its anterior part are extremely rare and present a diagnostic dilemma.  aetiology is multifactorial and is mainly...

INTRODUCTION Septoplasty, or surgical correction of the deviated septum, is an elective, routinely performed rhinologic procedure to address nasal airway obstruction. In many cases, resected septal cartilage and bone fragments are sent for pathologic review, although there is no consensus on this practice. We reported two cases of incidentally diagnosed lymphoma after elective septoplasty and d...

OBJECTIVE To investigate the anatomical characteristics of the nasal cavity and paranasal sinuses in relation to the presence of sinusitis in patients with cleft lip and palate. DESIGN Retrospective survey. SETTING Tertiary care hospital. PATIENTS Forty-seven consecutive patients with cleft lip and alveolus with or without cleft palate. MAIN OUTCOME MEASURES The patients underwent compu...

BACKGROUND There is no current acceptable approach for intracardiac beating-heart interventions. We have adapted real-time 3-dimensional echocardiography with specialized instrumentation to facilitate beating-heart repair of atrial septal defects and mitral valve plasty to investigate the feasibility of real-time 3-dimensional echocardiography-guided cardiac surgery. METHODS In experiment I a...

OBJECTIVES/HYPOTHESIS Tissue-engineered septal cartilage may provide a source of autologous cartilage for repair of nasal defects. Production of clinically useful neocartilage involves multiple steps that include manipulating the culture environment. Partial pressure of oxygen (ppO(2) ) is a property that has been shown to influence cartilage development. Specifically, studies suggest low ppO(2...

AIM To establish, via computer simulation, the effects of patient response variability and staircase starting level upon the accuracy and repeatability of static full threshold visual field tests. METHOD Patient response variability, defined by the standard deviation of the frequency of seeing versus stimulus intensity curve, is varied from 0.5 to 20 dB (in steps of 0.5 dB) with staircase sta...

Objective: It is known that deviation of the septum plays an etiological role in obstructions formed osteomeatal complex. In this study, it was aimed to evaluate effect degree nasal on distances between bone structures forming Method: The research universe obtained by retrospectively scanning 1200 computed tomography (CT) images January 2018-December 2019 PACS archive Department Radiology Sivas...
