OBJECTIVE To obtain objective average measurements of the profile and frontal facial soft tissue to be used as a guide for aesthetic treatment goals. Methods and Materials : This observational study included 110 females and 130 males high school students aged 16-18 years. None of the subjects had any facial deformities. All of them and their parents gave consent to take part in this study. In e...

PURPOSE To use anterior segment optical coherence tomography (AS-OCT) to analyze ciliary muscle morphology and changes with accommodation and axial ametropia. METHODS Fifty prepresbyopic volunteers, aged 19 to 34 years were recruited. High-resolution images were acquired of nasal and temporal ciliary muscles in the relaxed state and at stimulus vergence levels of -4 and -8 D. Objective accomm...

OBJECTIVE To investigate the aerodynamic consequences of conservative unilateral inferior turbinate reduction using computational fluid dynamics methods to accomplish detailed nasal airflow simulations. DESIGN A high-resolution, finite-element mesh of the nasal airway was constructed from magnetic resonance imaging data of a healthy man. Steady-state, inspiratory airflow simulations were cond...

background and objectives: nasal polyposis is a diseases resulting from complex pathogenetic mechanisms. some studies showed that tgfβ1 had significant role in this pathogenesis. in this study, we investigated the roe of cytokines and mediators in polyp development. material and methods: in this case- control study, healthy nasal mucosal samples were obtained from 24 people undergoing septoplas...

abstract facial defects not only impact on the function and quality of life but also affect the psychological well-being and social behavior of patients. a nasal prosthesis can re-establish the esthetics and anatomical contour in patients with mid-facial defects, often more effectively than surgical reconstruction. for successful results, many factors such as retention, texture, color match and...

This study represents an unusual case of mucormycosis localized in nasal cavity of a German shepherd dog. The patient was a 1-year-old male guard dog with unilateral nasal epistaxis, mucopurulent nasal discharge, sneezing and nose pawing. The dog had a history of head trauma about 2 months before admission, which was associated with mild self-limited epistaxis. Initial nasal rhinoscopy showed s...

background: nasal intermittent positive pressure ventilation (nippv) is a non-invasive ventilatory mode, which delivers mechanical ventilation via nasal tubes or prongs. the present study was conducted to compare the efficacy of nippv and nasal continuous positive airway pressure ventilation (ncpap) in reducing the need for intubation in preterm infants with respiratory distress syndrome (rds)....

introduction: environmental fungi, molds and yeasts, can infest the nasal cavity through inhaled air. there is some evidence that they could be the main cause of chronic rhinosinusitis (crs) but little is known about the normal fungal flora in the human nose. the objective of this study was to assess the normal fungal flora of the nasal mucus in adults in kerman. materials and methods: we condu...

BACKGROUND Heated humidified high-flow nasal cannula (HFNC) is thought to be comparable with nasal CPAP. The effect of multimodality mid-level respiratory support use in the neonatal ICU is unknown. The objective of this work was to evaluate the effect of introducing HFNC on length of respiratory support and stay. METHODS A chart review was conducted on subjects at 24-32 weeks gestation requi...

  Abstract:   Background: The most important and complex phenomenon of respiratory function of the nose is related to different nasal anatomy. The differences in facial anatomic structure between different races may also be reflected in nasal resistance and airflow. Caucasians has different facial anatomic structure which is the reflection of intranasal resistance or consequence of airflow. The...
