Nasal Injury
Conditions
Brief summary
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.
Interventions
PROCEDUREConventional osteotomy
The nasal skeleton was accessed using a closed approach or an open approach is done via a transcolumellar and infracartilaginous incision. Osteotomy was made using osteotomes.
PROCEDUREPiezosurgery osteotomy
full exposure of the nasal bony pyramid is needed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Operative time | During procedure | Operation duration will be calculated |
| Visual analogue score | immediately after procedure | The VAS consists of a 10cm line, with two end points representing 0 ('no pain') and 10 ('pain as bad as it could possibly be') |
| Change in periorbital edema | Baseline and 1 week | Grade 1 - No coverage of iris with eyelids, Grade 2 - Slight coverage of iris with swollen eyelids, Grade 3 - Full coverage of iris with swollen eyelids, Grade 4 - Full closure of eyes. |
| Change in eccyhmosis | Baseline and 1 week | Grade 1 - Eccyhmosis upto the medial one-third part of lower and /or upper eyelid, Grade 2 - Ecchymosis upto the medial two-third part of the lower and/or upper eyelid. Grade 3 - Ecchymosis up to the full length and /or upper eyelid. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Functional - aesthetic outcome | immediately after procedure | 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. |
