Proboscis lateralis: a report of two cases.
Proboscis Lateralis (PL) is one of the congenital anomalies of the nose which presents as obvious deformity. This is a report of two cases of the rare anomaly PL. One presented with right PL and the second presented with left PL. In this rare anomaly, the nasal cavity on one side is completely normal while on the affected side, the nasal cavity is replaced by a tube of skin and soft tissue attached to the inner canthus of the eye. This anomaly occurs sporadic as an isolated defect or in association with other anomalies. It is usually associated with failure of the paranasal sinuses and the nasolacrimal duct development. Embryologically, this anomaly is a result of imperfect fusion of the lateral nasal wall and maxillary processes (Int. J. Pediatr. Otorhinolaryngol. 23 (1992) 275).
