Deformities of the nostrils and alar region are among the very common clinically defects, which interfere with the functional anatomy of the nose. This case paper exemplifies the management of a bilateral external nasal valve area defect in a patient following a nasal reconstruction done using a forehead flap. The nasal stents were rendered to the patient for comfortable breathing by maintainin...

The nose may help protect the lower respiratory tract from the effects of ambient ozone by scrubbing ozone from inspired air. Reductions in both nasal resistance and nitric oxide production with exercise may influence the efficiency of ozone uptake in the nose. Nasal ozone uptake was measured in 10 healthy volunteers before and after 15 min of moderate bicycle exercise. Ozone (0.2 parts/million...

In this paper, we propose a method for fast and accurate extraction of feature points such as pupils, nostrils, mouth edges, and the like from dynamic images with the purpose of face recognition. Accuracy of face extraction with these feature points used as criteria greatly affects the capabilities of face recognition methods based on pattern matching. This processing must be performed rapidly,...

To investigate the temporal relationships of mediator release and physiological changes during the early response to allergen, we challenged allergic individuals intranasally with antigen and followed their responses. This was done by using small filter paper disks to challenge one nostril and collect secretions from both the challenged and the contralateral nostril, thus enabling us to evaluat...

Navigation, finding food sources, and avoiding danger critically depend on the identification and spatial localization of airborne chemicals. When monitoring the olfactory environment, rodents spontaneously engage in active olfactory sampling behavior, also referred to as exploratory sniffing [1]. Exploratory sniffing is characterized by stereotypical high-frequency respiration, which is also r...

Background. The upper lip-nose complex contributes significantly to the concept of symmetry and proportion of the face. A study of the morphology and aesthetic preferences of the lip-nose complex will provide a database that will serve as a guide for reconstruction. Subjects and Methods. Hundred Nigerian children participated in this study. Demographic data and standard photographs of the philt...

One of the earliest recordings in Egyptian mythology ofresuscitation was when Isis restored her husband Osiris by breathing into his mouth. The Bible has several accounts of resuscitation using the mouth or nostrils. In Genesis it was recorded that when forming Adam, God is said to have ". . . breathed into his nostrils the breath of life". In the first book of Kings, Elijah resuscitated the dy...

we report a case of human nasal nosocomial myiasis in a 69-year-old rural man with numerous live maggots in nostrils. the patient was admitted in emergency ward due to dyspnea. after 72 hours the companion of patient discovered larva. the presence of the third instar larva indicated that the infestation was not more than three days. the collected instars were cleared, fixed and morphological st...

The present paper describes a set of methods for the extraction of facial features as well as for the determination of the gaze direction. The ultimate goal of the approach followed is to deene a suucient set of feature distances so that a unique description of the structure of a face is produced. Eyebrows, eyes, nostrils, mouth, cheeks and chin are considered as interesting features. The candi...

Nasal airflow is greater in one nostril than in the other because of transient asymmetric nasal passage obstruction by erectile tissue. The extent of obstruction alternates across nostrils with periodicity referred to as the nasal cycle. The nasal cycle is related to autonomic arousal and is indicative of asymmetry in brain function. Moreover, alterations in nasal cycle periodicity have been li...
