Background:
Osteotomy is a crucial step in rhinoplasty, which can have a significant impact on the outcome. In addition to previous percutaneous (external perforating) and endonasal (internal) approaches, piezosurgery has been used in rhinoplasty practice since 2007. This experimental model was planned to compare the three osteotomy techniques.
Materials And Methods:
This study was performed on a caprine skull osteotomy model. Three groups were created from 12 animals, namely, endonasal continuous, external perforating, and piezosurgery groups. All the groups were evaluated for bone gaps, comminuted fractures, and nasal mucosa damage.
Results:
There were no comminuted fractures and mucosal defects in any of the samples in the piezo osteotomy group. The average amount of bone gap at the osteotomy site and the nasal mucosa damage was lower in the piezo group than in the other groups. The time required for the osteotomy was shorter in the endonasal group, similar to that in the external and piezo groups.
Conclusion:
New techniques are constantly being developed to achieve better results in rhinoplasty. As a natural consequence to technological developments, new devices are being introduced to rhinoplasty practice. Piezo is one such device. We have found that piezo osteotomy has resulted in lower amounts of nasal mucosal damage and comminuted fractures. We believe that piezo can safely be used in rhinoplasty practice until newer and more reliable technologies are being developed.

01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
