External or internal lateral osteotomy: why I choose the external percutaneous approach.

ABSTRACT

The authors present their surgical experience with the management of patients with dorsum deformities using a precise technique the external percutaneous approach. The indications for this technique have still not been set out very clearly in the rhinological textbooks or manuals, and so novices (and not only novices) have difficulty in understanding and applying it. We therefore try to systematise and clarify these indications in brief, together with the technical details, providing a comparison with another technique that is in very widespread use at present the internal lateral osteotomy. Although the external percutaneous approach is not used very often--in our experience in 30% of cases only--we find the results very satisfactory and we recommend it when it is required by the anatomic conditions.
