A new species of the genus Euphlyctis is described from the Barisal district of Bangladesh and compared with its morphologically similar and geographically proximate congeners. The new species is highly divergent in comparison to other congeneric species on basis of sequence divergence in mitochondrial DNA gene sequences (ranging from 5.5% to 17.8% divergence). Euphlyctis kalasgramensis sp. nov...

After cleft lip repair, many patients suffer from nasolabial fistulas, asymmetrical nasal floor, or an indistinct nostril sill, as well as intraoral wound dehiscence and subsequent scar contracture of surgical wounds leading to vestibular stenosis. For successful primary nasolabial repair of complete cleft deformity of the primary palate, cleft surgeons need special care in reconstructing the s...

Acoustic rhinometry could numerically describe upper airway condition of air draft by drawing a graph plotting the distance from the nostril vs. the crosssectional area. Some decreases on the graph correspond to the typical anatomic structures of human nasal cavity. The 3-dimensional, computing fluid dynamic model of the same person was developed based on computed tomography scans. The veracity...

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...

Cephalic malposition of lower lateral cartilage (CMLLC) is one of the most common objects of aesthetic and functional rhinoplasty. Constantian wrote in his article that 68% of his primary rhinoplasty cases had lateral crural malpositioning.1 To diagnose CMLLC the surgeon has to observe several parameters that were described by Sheen: malposition is “any displacement of the lateral crura from th...

Supernumerary nostril is a very rare congenital anomaly. It can be unilateral or bilateral, and it sometimes occurs in the presence of other congenital deformities. Behind the external opening of a supernumerary nostril is a small accessory nasal cavity, which may or may not communicate with the normal nasal cavity on the same side. We describe a new case in which the supernumerary nostril with...

BACKGROUND Reports suggest that vigilance or sustained attention increases sympathetic activity. A persistent increase in sympathetic activity can lead to an increase in blood pressure. Alternate-nostril yoga breathing has been shown to be useful to (i) improve attention and (ii) decrease the systolic and diastolic blood pressure. Earlier studies did not report simultaneous recordings of the bl...

The majority of bacteria detected in the nostril microbiota of most healthy adults belong to three genera: Propionibacterium, Corynebacterium, and Staphylococcus. Among these staphylococci is the medically important bacterium Staphylococcus aureus. Almost nothing is known about interspecies interactions among bacteria in the nostrils. We observed that crude extracts of cell-free conditioned med...

Unilateral nostril hypoplasia is an extremely rare congenital malformation of unknown etiology, and only a few cases have been reported in literature. Owing to variability and complexity of the deformity, surgical correction of unilateral nostril hypoplasia represents one of the most significant reconstructive challenges to reconstructive plastic surgeons. We report a 7-year-old Vietnamese chil...
