The Evaluation of Piezo and Endonasal Osteotomy Methods on Postoperative Healing Process in Septorhinoplasty

Patients will undergo median-oblique and lateral osteotomy, with conventional 2 mm guarded, straight osteotome.

Piezo is a system for cutting bone with micrometric ultrasonic piezoelectric vibrations, with varying frequency and cutting energy. The device consists of a platform with a powerful piezoelectric hand piece and employs a functional frequency between 25-29 kHz. The device is fitted with a cooling irrigation system with a 0-60 cc/min variable sterile solution flow. Specific inserts and scalpels act in a linear vibration pattern, with a spatial range between 60 and 210 microns, moved by an ultrasonic power that exceeds 5 watts, reaching up to 16 watts.
