It is well-known and universally acknowledged that rhinoplasty is the most demanding procedure in facial aesthetic surgery. Postoperatively nasal osteotomies result in variable degrees of edema and ecchymosis and surgeons have tried various techniques, instruments, and postoperative methods to diminish these uncomfortable morbidities. Piezosurgery is used nowadays to decrease the incidence of injured soft tissues and vital structures passing near the osteotomy line. Its use in rhinoplasty was advocated to prevent unwanted back fractures as well as to decrease bleeding while keeping the nasal mucosa intact thus minimizing postoperative sequelae.

Functional - aesthetic outcome
The SCHNOS is a 10-item self-rated questionnaire that uses a Likert-like 0-5 scale ('no problem' to 'extreme problem'). The SCHNOS does not produce a combined total score, but two scores - one for each domain, an obstruction score (SCHNOS-O) and a cosmesis score (SCHNOS-C) The SCHNOS-O is calculated as a sum of scores of items 1-4 divided by 20 and multiplied by 100. The SCHNOS-C score is calculated as a sum of scores of items 5-10 divided by 30 and multiplied by 100.
Time frame: immediately after procedure
