• To evaluate the results of Metzenbaum 's technique in correction of the Caudal end septal deviation on nasal airway obstruction

Deviation of Nasal septum in different parts may have various functional or aesthetic effects . The etiology of a deviated septum is generally congenital, but may also be as a result of trauma or iatrogenic causes. Most important is the Caudal septal deviation which narrows the airway and impairs major mechanisms supporting the tip, leading to tip-ptosis and airway collapse. .The correction of caudal septal deviations can be a challenging problem so many techniques have been described and tested to correct caudal septal deflections . Attempts to correct nasal septal deformities were described in the medical literature as early as the late 19th century , and till now there is not one specific technique that is agreed upon by surgeons worldwide.
