Bifid nose

Bifid nose (also known as cleft nose, nasal cleft, or median nasal cleft) is a rare congenital malformation characterized by a partial or complete vertical splitting of the nose along the midline. This condition results from incomplete fusion of the nasal placodes during embryonic development, typically between the fourth and eighth weeks of gestation. The severity can range from a minor midline groove or notch at the nasal tip to a complete separation of the two nasal halves with widely spaced nostrils and a broad nasal bridge. In more severe forms, the underlying nasal cartilage and bone may also be cleft, and the condition may be associated with a widened nasal dorsum, hypertelorism (widely spaced eyes), or a midline dermoid cyst. Bifid nose can occur as an isolated anomaly or as part of broader syndromic conditions, including frontonasal dysplasia, Pai syndrome, or other midline developmental defects. When syndromic, additional features may include midline cleft lip, cranium bifidum occultum, intracranial lipomas, or other craniofacial anomalies. The body systems primarily affected are the craniofacial structures, particularly the nose and midface. Respiratory function may be impacted in severe cases due to structural abnormalities of the nasal passages. Treatment is primarily surgical and aims to reconstruct the nose for both functional and cosmetic purposes. Surgical repair typically involves rhinoplasty techniques to bring the separated nasal halves together, reconstruct the nasal framework, and achieve a more typical nasal appearance. The timing and complexity of surgery depend on the severity of the defect and whether associated anomalies are present. Multidisciplinary care involving craniofacial surgeons, otolaryngologists, and geneticists is often recommended, particularly in syndromic cases. Outcomes are generally favorable with appropriate surgical intervention, though multiple procedures may be needed as the child grows.
