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 lat...

OBJECTIVE The purpose of this prospective observational study was to evaluate the relationship between nasal morphology and maxillary skeletal pattern. The clinical significance was to emphasize the importance of role of nasal pattern in diagnosis and treatment planning. MATERIALS AND METHODS The sample included the pre-treatment lateral cephalometric radiographs of 180 South Indian adults (9...

OBJECTIVE: To establish reference values for fetal nasal bone length measurements between 11 and 15 gestational weeks in a Brazilian population. MATERIALS AND METHODS: A cross-sectional study was developed with 171 normal pregnant women between their 11th and 15th gestational weeks. The fetal nasal bone was measured by means of transabdominal ultrasound in all of the cases. The 5th and 95th per...

Objectives: 1.To investigate the relationship between nasal morphology in relation to sagittal and vertical maxillary skeletal pattern and 2.To know the relationship between the degree of upturn of the nose and the inclination of the palatal plane. Materials and Methods: Pretreatment lateral cephalograms of 60 adults of age 18-27 years with no previous history of trauma, surgical intervention, ...

In the recent years, sonographic images of fetal nose have gained popularity in detecting trisomy 21 and other aneuploidies. Reference values for nasal bone length have been reported in different countries and ethnic populations. However, there was no reference range for the fetal nasal bone length (NBL) in the Filipino population. This prospective, cross-sectional study was conducted to establ...

BACKGROUND Nasal bone assessment has been incorporated into Down syndrome screening in first trimester. Several studies have established the normal reference values for fetal nasal bone length in the first trimester, which were found to be varied by population. However, the study on reliability of nasal bone length measurement was limited with contradictory results. This study aimed to investig...
