HPO HP:0000418 Narrow nasal ridge "Decreased width of the nasal ridge." [PMID:19152422] This feature may be accompanied by narrow nasal bridge and narrow nasal base, which should be coded separately. HP:0011119
HPO HP:0000419 Abnormality of the nasal septum "An abnormality of the nasal septum." [HPO:probinson] HP:0000366
HPO HP:0000420 Short nasal septum "Reduced superior to inferior length of the nasal septum." [HPO:probinson] HP:0000419
HPO HP:0000421 Epistaxis "Epistaxis, or nosebleed, refers to a hemorrhage localized in the nose." [HPO:probinson] HP:0000366, HP:0001892
HPO HP:0000422 Abnormal nasal bridge morphology "Abnormality of the nasal bridge, which is the saddle-shaped area that includes the nasal root and the lateral aspects of the nose. It lies between the glabella and the inferior boundary of the nasal bone, and extends laterally to the inner canthi." [HPO:probinson, PMID:19152422] The nasal root is the most depressed, superior part of the nose along the nasal ridge. HP:0005105
HPO HP:0000426 Prominent nasal bridge "Anterior positioning of the nasal root in comparison to the usual positioning for age." [PMID:19152422] A prominent nasal bridge can occur irrespective of the width of the nasal bridge, and the width should be assessed separately. The nasal bridge becomes more prominent with age. Although the nasal root may be anteriorly placed without increasing the space between the eyes, prominence of the nasal bridge may be accompanied by Telecanthus or ocular Hypertelorism. If such findings are present these should be coded separately. Deep-set eyes may lead to the impression of a prominent nasal bridge, but this finding should be coded separately. HP:0000422
HPO HP:0000429 Abnormality of the nasal alae "An abnormality of the Ala of nose." [HPO:probinson, PMID:19152422] The nasal ala is the tissue comprising the lateral boundary of the nose, inferiorly, surrounding the naris. HP:0010938
HPO HP:0000430 Underdeveloped nasal alae "Thinned, deficient, or excessively arched ala nasi." [PMID:19152422] The alae nasi are the lateral portions of the nose or the wings of the nostrils, which partly encircle the nostrils (nares). They are usually about the width of the columella, but vary greatly depending on the shape of the nostril. Note that individuals may be described as having a Cleft ala nasi, but have a severely underdeveloped ala nasi. In an underdeveloped ala the continuity of the tissue encircling the nostril is undisturbed while in a cleft it is disrupted. With severe hypoplasia of the nasal alae, the nasal tip may appear depressed. HP:0000429, HP:0009924
HPO HP:0000431 Wide nasal bridge "Increased breadth of the nasal bridge (and with it, the nasal root)." [HPO:probinson, PMID:19152422] Care should be taken to distinguish between increased width of bone and Fullness of paranasal tissue. A wide nasal bridge should be distinguished from Telecanthus and Hypertelorism. A wide nasal bridge can be either prominent or depressed, which should be coded separately. HP:0000422
HPO HP:0000433 Abnormal nasal mucosa morphology HP:0000366
HPO HP:0000434 Nasal mucosa telangiectasia "Telangiectasia of the nasal mucosa." [HPO:probinson] HP:0000433, HP:0100579
HPO HP:0000436 Abnormality of the nasal tip "An abnormality of the nasal tip." [HPO:probinson, PMID:19152422] The nasal tip is located at the junction of the inferior margin of the nasal ridge and the columella. Commonly, it is the part of the nose furthest from the plane of the face. In rare circumstances, such as markedly prominent and convex nasal profiles, other parts of the ridge may be further removed from the facial plane. HP:0010938
HPO HP:0000437 Depressed nasal tip "Decreased distance from the nasal tip to the nasal base." [PMID:19152422] This often accompanies a Short columella, Overhanging nasal tip, and Underdeveloped nasal tip, but these should be assessed and coded separately. HP:0000436
HPO HP:0000444 Convex nasal ridge "Nasal ridge curving anteriorly to an imaginary line that connects the nasal root and tip. The nose appears often also prominent, and the columella low." [PMID:19152422] HP:0011119
HPO HP:0000445 Wide nose "Interalar distance more than two standard deviations above the mean for age, i.e., an apparently increased width of the nasal base and alae." [PMID:19152422] HP:0005105
HPO HP:0000446 Narrow nasal bridge "Decreased width of the bony bridge of the nose." [PMID:19152422] The narrowness may be accompanied by a sharp, keel-shaped appearance. The nasal bridge may narrow with age. HP:0000422
HPO HP:0000447 Pear-shaped nose HP:0005105
HPO HP:0000448 Prominent nose "Distance between subnasale and pronasale more than two standard deviations above the mean, or alternatively, an apparently increased anterior protrusion of the nasal tip." [PMID:19152422] HP:0005105
HPO HP:0000451 Triangular nasal tip HP:0000436
HPO HP:0000452 Choanal stenosis "Abnormal narrowing of the choana (the posterior nasal aperture)." [HPO:probinson] HP:0000415
HPO HP:0000453 Choanal atresia "Absence or abnormal closure of the choana (the posterior nasal aperture)." [HPO:probinson] HP:0000415
HPO HP:0000454 Flared nostrils HP:0000429
HPO HP:0000455 Broad nasal tip "Increase in width of the nasal tip." [HPO:probinson, PMID:19152422] Nasal tip width is assessed at the anterior junction of the alae and the tip. This is easier in persons with a somewhat squared shape of the nasal tip. This may be best viewed from the inferior aspect of the nose. No objective measures are available. See Bulbous nose for a related term. HP:0000436, HP:0000463
HPO HP:0000456 Bifid nasal tip "A splitting of the nasal tip. Visually assessable vertical indentation, cleft, or depression of the nasal tip." [HPO:sdoelken, PMID:19152422] This is a rare congenital deformity due to failure of the paired nasal processes to fuse to a single midline organ during early gestation. HP:0000436
HPO HP:0000457 Depressed nasal ridge "Lack of prominence of the nose resulting from a posteriorly-placed nasal ridge." [HPO:probinson, PMID:19152422] The adjective 'depressed' here does not indicate an active process but a status. The feature should be assessed in a profile view. This finding is typically associated with a Short columella, but this should be assessed separately. HP:0011119
