Introduction: In Latin America, the prevalence of mesiodens is 1.7%. Mesiodens impacted towards base nostril can cause complications such as: pain, epistaxis, rhino sinusitis, nasal obstruction and congestion even eruption through nostril. Case report: A 7-year-old male patient with no clinical pathological data came for consultation due to interference in occlusion caused by a palatine erupted...

On the 30th March, 1950, a tea garden female labourer, aged 34 years, came to me with the complaints of epistaxis from the left nostril, swelling, pain, irritation and gnawing sensation in the nose. The trouble had started 3 days ago with slight pain and sanguineous running from the left nostril and on the day previous to her admission she had noticed a worm came out with the discharge. The pat...

see nothing. Then it occurred to me, that the condition might be due to a leech in the nostril. I applied to the affected nostril, a turpentine swab and a wet cotton plug. The leech came out and I caught it in a tray containing water, in which it lived for a few hours. Remarks.?Invasion of the nasal cavity and ears is quite common in places near coffee estates, which are infested very heavily w...

Histopathological effects of different sublethal concentrations (1, 2 and 4 mg/l) of diazinon, an organophosphorus pesticide, on gill, liver, spleen and kidney of grass carp (Ctenopharyngodon idella) were studied after 1, 7, 15, 30 and 45 days post-exposing fishes weighting 850 ± 155 g to the toxicant for 12 hours at 18-22ºC. In addition, tissues of nostril were examined for transmission electr...

The present paper proposes a novel methodology to monitor sleep apnea through thermal imaging. First, the nostril region is segmented and it is tracked over time via a network of cooperating probabilistic trackers. Then, the mean thermal signal of the nostril region, carrying the breathing information, is analyzed through wavelet decomposition. The experimental set included 22 subjects (12 men ...

Many dinosaurs have enormous and complicated bony nasal apertures. Functional interpretation requires knowledge of the location of the external opening in the skin. Traditionally, the fleshy nostril of dinosaurs has been placed in the back of the bony opening, but studies of extant dinosaur relatives suggest that it is located far forward. Narial blood supply and cavernous tissue corroborate th...

Detailed descriptions of the ideals of columellar aesthetics and nostril shape are conspicuously lacking from the medical literature. Achieving an aesthetic nasal base is critical to an optimal rhinoplasty result. Deviations in the columella and variations in its width and height lead to distortion of nostril shape and frequently compromise function. Six types of columellar disproportion are pr...
