OBJECTIVES/HYPOTHESES Nasal bone length is commonly referenced in the rhinoplasty literature. It has been suggested that short nasal bone length may predispose one to a greater risk of middle vault collapse after rhinoplasty. However, there are limited data available on what constitutes the normal dimensions of these pertinent structures of the nasal sidewall. In addition, no data exist on the ...

OBJECTIVE This study aims to investigate the length and shape of the nasal bones in fetuses with trisomy 21 at 16-24 weeks' gestation. METHOD We acquired three-dimensional volumes of the fetal profile from 41 fetuses with trisomy 21. The multiplanar mode was used to measure nasal bone length in the exact midsagittal plane and in parasagittal and oblique views of the fetal face and to examine ...

Background: The measurement of nasal bone length (NBL) according to gestational age and setting nomogram helps to ascertain NB hypoplasia. This can be used for early detection of trisomy 21 and other chromosomal abnormalities in low risk population. The objective of the study was to obtain nomogram of fetal nasal bone length at 11-14 weeks gestation with known prognosis pregnancies. Methods: A ...

BACKGROUND Hyperactivity of depressor septi nasi muscle leads to smiling deformity and nasal tip depression. Lateral fascicles of this muscle help in widening the nostrils. The purpose of this study was to evaluate the relationship between the nasal length changes and the alar base and the alar flaring changes during smile. METHODS Standard photographs are performed in the face and lateral vi...

OBJECTIVE To define baseline aesthetic dimensions of the nasal aperture in 3 different racial groups. METHODS Healthy volunteers from 3 different racial groups (15 white, 15 Chinese, and 15 Indian men) were enrolled in the study at the Department of Otolaryngology, University of Dundee, Dundee, Scotland. Those with a history of nasal or facial surgery or trauma were excluded from the study. I...

OBJECTIVE To establish a normal range of nasal-bone length at 16-24 weeks' gestation by the use of three-dimensional (3D) ultrasound and to investigate the effect of deviations from the exact mid-sagittal plane on the measurement of nasal-bone length. METHODS We acquired 3D volumes of the fetal profile from 135 normal fetuses at 16-24 weeks' gestation. The multiplanar mode was used to obtain ...

anthropometry, a useful method for evaluating craniofacial soft tissues, makes the quantitative description of the face possible. it also assesses the degree of disharmony and imbalance in the growth and development of the face. the aim of this study was to examine the overall common age-related changes of nasomaxillary complex of adolescent boys in northeast iran. three- hundred- twelve 12 to ...

PURPOSE To evaluate long-term results in the bilateral cleft lip repair by Mulliken's method, using anthropometric measurements, we assessed the growth of the nose and upper lip after the operation by comparing with those from 30 children without bilateral cleft lip. MATERIALS AND METHODS Forty-four patients had their bilateral cleft lip and nasal deformity repaired simultaneously by Mulliken...
