Pathology and correction of the stenosed nasal vestibule.

Stenosis of the nasal vestibule is a frequent cause of nasal obstruction. An anatomical study of the region will enable one to understand the physiopathology of the stenosis of the floor of the vestibule which frequently accompanies septal deformities in the premaxilla region, or which occurs after septal surgery. The correction of this circumferential stenosis has been handled satisfactorily by the use of a "Z" plasty of the floor of the vestibule. Pertinent anatomical material, schematic drawings, and clinical cases are presented.
