Congenital nasal aperture stenosis is an unusual cause of upper airway obstruction among neonates, and rarely presents as unilateral. Most commonly presents as choanal atresia. A CT evaluation is essential to confirm the diagnosis. Both surgical and conservative management can be applied, based on the severity of the associated clinical presentation; however, the very rare unilateral condition ...

Brachycephalic syndrome develops as a result of a specific build of splanchnocranium. In dogs of brachycephalic breeds, an impairment of correct gas exchange occurs. 5 French bulldogs at the age of 11-14 months, which suffered from continuous mixed-type dispnoea and lowered effort tolerance, were examined. Apart from the above-mentioned symptoms, the occurrence of strong external nostril stenos...

Introduction: Neonatal nasal airway obstruction induces various degrees of respiratory distress. The management of this disease, including surgical repair, will depend on the severity and location of the obstruction. We describe here a case of congenital nasal nostril stenosis that required surgical repair for stenting of both nares after coanal atresia repair.   Case Report: A 2 days old femal...

VACTERL association represents a rare condition with broad spectrum of coexisting congenital abnormalities. Although multifactorial origin has been described, the etiology is still unclear. Prenatal diagnosis can be challenging, as specific characteristics may difficult to determined before birth. This case report describes finding multiple abnormalities in male fetus at 30 weeks gestation. The...

Nostril structures are important characteristics for generic diagnosis in Nemacheilidae and Cobitidae. Based on phylogenetic analysis, we found that 10 genera within (Eonemachilus, Guinemachilus, Lefua, Micronemacheilus, Oreonectes, Paranemachilus, Protonemacheilus, Traccatichthys, Troglonectes, Yunnanilus) shared tube-shaped anterior nostrils formed a monophyletic group. Morphologically, the l...

Effect of pressure application by a crutch to the axilla of the side of the dominant right nostril on the pattern of nostril dominance with emphasis on the time sequence of changes and recovery was studied in the young male Nigerians. The nostril dominance was assessed from the percentage of tidal volume flowing through the right and left nostril passages during expiratory phase (7). Applicatio...

There is increasing interest in the fact that breathing exclusively through one nostril may alter the autonomic functions. The present study aimed at checking whether such changes actually do occur, and whether breathing is consciously regulated. 48 male subjects, with ages ranging from 25 to 48 years were randomly assigned to different groups. Each group was asked to practice one out of three ...

The role of the inspiratory and expiratory airflow through nostrils during the process of breathing in the reflex reciprocal congestion and decongestion of the nasal cycle was examined in this study. Air flow through each nostril was measured separately in male subjects before and after four types of breathing practices for 15 min each consisting of (1) inspiration through the patent nostril an...
