Patients often present with a complaint of nasal blockage, either primarily, or in conjunction with aesthetic concerns. The evaluation of the patient with nasal obstruction involves a comprehensive hi...
In clinical practice, lateral nasal wall collapse during forced inspiration is widely regarded as a sign of nasal obstruction or criterion indicating nasal valve surgery. This study aims to evaluate t...
In this study, lateral nasal wall collapse is determined by the degree of lateral nasal wall triangle (LNWT) area reduction on frontal view during forced inspiration compared to quiet inspiration. LNW...
The average LNWT area ratio of the patient (n = 24) and control groups (n = 27) was 0.96 and 0.83 respectively (...
Lateral nasal wall collapse is not related to a patients' nasal obstruction....
To examine the prevalence and nature of nasal endoscopic findings in patients referred for structural nasal obstruction, and analyze how such findings influence the preoperative evaluation or operativ...

University-based academic otolaryngology practice....
Nasal endoscopy was performed by a single surgeon and the exam findings were documented. Patient demographics, variables in the patient history, Nasal Obstruction Symptom Evaluation scores, and an Eas...
A total of 82 of 346 patients (23.7%) had findings on rigid nasal endoscopy not appreciable on anterior rhinoscopy. Prior nasal surgery (p = .001) and positive allergy testing (p = .013) were signific...
In patients referred for surgical management of nasal obstruction, findings on nasal endoscopy otherwise undetected with anterior rhinoscopy are most common in but certainly not limited to those with ...
The anterior nose is the nasal segment with the highest resistance to airflow. In a hospital-based case-control study, we compared cross-sectional areas of the nasal cavities anterior to the piriform ...
CT-CSA could be reproducibly identified at angles of 0...
CT-CSA ranged from 7 to 250 mm...
Cross-sectional areas of the anterior nose perpendicular to the direction of nasal airflow, which is considered relevant in terms of flow physics, can be reliably measured using CT. Anterior nasal cav...
Rapid maxillary expansion (RME) expands the maxillary dentition laterally and improves nasal airway obstruction. However, the incidence of nasal airway obstruction improvement after RME is approximate...
Sixty subjects (21 boys; mean age 9.1 years) were divided into 3 groups according to their nasal airway condition (control, nasal mucosa hypertrophy, and obstructive adenoids), and those requiring RME...
The cross-sectional area of the nasal airway significantly increased after RME in all 3 groups. The pressures in the control and nasal mucosa groups significantly reduced after RME but did not change ...
The incidence of improvement in nasal airway obstruction after RME depends on the nasal airway condition (nasal mucosa hypertrophy and obstructive adenoids). In patients with nonpathologic nasal airwa...
Motivated by clinical findings about the nasal vestibule, this study analyzes the aerodynamic characteristics of the nasal vestibule and attempt to determine anatomical features which have a large inf...
To determine the independent predictive role of nasal obstruction in resistant hypertension (RH) in uncontrolled hypertensive patients with obstructive sleep apnea (OSA)....
This prospective cohort study comprised of 236 OSA patients with uncontrolled blood pressure (BP) using 1 or 2 classes of antihypertensive drugs visiting Sleep Medicine Center from April 2021 to March...
After 5 month follow-up, 217 participants were included for final data analysis. Ninety-five subjects had nocturnal nasal obstruction with a higher proportion of RH (36.8% vs. 17.2%, p = 0.001) compar...
Nasal obstruction is an independent predictor of RH in uncontrolled hypertensive patients with OSA. In addition to the treatment of OSA, assessment and treatment of nasal obstruction should be conside...
Mouth breathing (MB) is a symptom of obstructive sleep apnea (OSA) in children, but its diagnosis remains challenging. The main objectives of our study were to evaluate whether parents' and physician'...
Ninety-three children (median age: 10.6 years, range 3-18) with moderate to severe OSA prospectively underwent otorhinolaryngologist (endoscopy, acoustic rhinometry and pharyngometry allowing calculat...
Thirty-eight children (41%) were mouth (parental criterion: MB often or always, median age 8.2 years) and 55 nasal (11.4 years, p = 0.016) breathers. The agreement of parental and physician diagnosis ...
MB diagnosis by parents is acceptable and is mainly related to nasal obstruction. A subset of children had MB by habit associated with worst OSA and increased pharyngeal compliance that could benefit ...
Obstructive sleep apnea (OSA) and nasal obstruction are common in the general population and frequently treated by otolaryngologists and facial plastic surgeons. Understanding the appropriate pre-, pe...
While surgeries to correct the anatomical malformations that cause nasal airway obstruction (NAO) are generally successful, the outcomes of such procedures are often unsatisfactory. The aim of the pre...
Thirty-four patients with nasal obstruction due to nasal septal deviation were included in this study. After randomization, the middle meatus was either opened or not opened during septoplasty. The pa...
The VAS scores and SNOT-20 responses improved significantly in both groups after surgery. The effective treatment rate based on the nasal congestion score (NCS) was 64.7% in the single group (septopla...
Opening the middle meatus may further improve the subjective perception of patency on the basis of septoplasty....
