Piano technique for frontal sinus setback: a technical note

Frontal sinus setback is a procedure used for addressing severe protrusion of the frontal area. Various surgical techniques have been developed over time to address frontal sinus abnormalities with varying etiologies and severity. The present article introduces the piano technique as a novel method for frontal sinus setback with less aggressiveness and complexity compared to other available methods, while being efficient in providing substantial long-term improvements in aesthetic outcomes. In this method, the anterior wall of the frontal sinus is divided into numerous rectangular bony segments attached to the superior area (like piano keys), which makes the process of shaping the frontal area easier, with the resultant more natural appearance post-surgically and eliminating the need for application of technical modifications and/or bone cement for filing the bone gap as used in conventional methods.
