T he tripod concept has proved to be a valuable model in understanding nasal tip dynamics. Peter A. Adamson, MD, FRCSC, and colleagues propose the M-Arch Model, which expands the nasal tripod concept by considering the nasal tip tripod in its entirety as an arch. This novel model stresses the importance of the overall length of the medial, intermediate, and lateral crural segments as they form ...

OBJECTIVE To test the hypothesis that surgery on the growing nasal septum does not adversely affect nasal and midfacial dimensions. DESIGN Paired study. SETTING Tertiary care center. PARTICIPANTS Children treated consecutively during a 4-year period; all had significant nasal obstruction and cosmetic disfigurement secondary to skeletal septal deformities. INTERVENTION Nasal septal surge...

Depressor septi nasi is an important muscle in the nose and upper lip dynamics.1-4 Hypertrophy of this muscle leads to a deformity during smiling presented by depression of nasal tip, shortening of upper lip, and a horizontal crease in upper lip.4 Rhino-gingivolabial syndrome was defined as depression of nasal tip, shortening of upper lip, and gingival show. This syndrome was attributed to the ...

BACKGROUND Adverse outcomes of pregnancy are a challenging health-care problem. Prediction of adverse pregnancy outcomes is important to prevent the morbidities of the foetus and the mother. AIMS To study the clinical interest of fetal nasal bone length in predicting adverse pregnancy outcomes in the first trimester of pregnancy. STUDY DESIGN A population-based retrospective cohort study. ...

OBJECTIVES This study was designed to evaluate the normal development of the nasal septum in Koreans using sagittal MRI for the valuable clinical information on septal procedures. METHODS Two hundred eighty patients who had their whole nasal septum visualized in the midline sagittal view were selected among the 3,904 patients with brain MRI from January, 2004 to December, 2006 at Dankook Univ...

OBJECTIVE The purpose of this study was to establish an Indian reference for normal fetal nasal bone length at 16-26 weeks of gestation. METHODS The fetal nasal bone was measured by ultrasound in 2,962 pregnant women at 16-26 weeks of gestation from 2004 to 2009 by a single operator, who performed three measurements for each woman when the fetus was in the midsagittal plane and the nasal bone...

OBJECTIVE To determine normal values in the size of nasal fossae to better delineate the concept of nasal stenosis in young infants with nasal obstruction and without choanal atresia. DESIGN Case series. SETTING Referral center. PATIENTS Consecutive sample of 62 infants (aged 0 to 6 months) with no craniofacial anomalies who underwent conventional axial computed tomography scans for a neu...

Nasal polyps (NP) is highly associated with the disorder of immune cells. Alternative polyadenylation (APA) produces mRNA isoforms with different length of 3'‑untranslated region (UTR) and regulates gene expression. It has been proven that this APA-mediated regulation of 3'UTR length is an immune-associated phenomenon. The aim of this study was to investigate the genome-wide alternative tandem ...

Turbinate destruction is an important diagnostic criterion in canine and feline nasal computed tomography (CT). However decreased turbinate visibility may also be caused by technical CT settings and nasal fluid. The purpose of this experimental, crossover study was to determine whether fluid reduces conspicuity of canine and feline nasal turbinates in CT and if so, whether CT settings can maxim...

The aim of this study was to clarify the morphological characteristics of craniomaxillary deviations in BALB/c-bm/bm mice with a spontaneous malocclusion (incisal transverse crossbite) using three-dimensional (3D) morphological measurements. Sixty female mice aged 13 and 25 weeks were divided into the following groups: control (BALB/c-+/+ mice, n = 20), norm (BALB/c-bm/bm mice with a normal occ...
