The nasal bossa: a complication of rhinoplasty.

A study of 1,033 consecutive rhinoplasties was undertaken to focus on etiology and treatment of nasal bossa. Of the 2% that developed bossa, the only consistent, statistically significant etiology factor was that of preoperative nasal asymmetry. There was no correlation with skin or cartilage characteristics. Those tips requiring alteration by the delivery technique were five times more likely to develop bossa than those treated by cartilage split or retrograde techniques. The surgical dilemma of treatment by either augmentation of the lesser side or resection of the bossa was discussed.
