Background and Objective: Hump reduction is performed by different instruments with inherent drawbacks. The present study was conducted to compare the frequency of complications in the nasal bridge area after hump reduction with piezosurgery and a conventional instrument (Rasp).
Materials and Methods: This clinical trial was carried out on 20 primary rhinoplasty patients. The patients were randomly assigned to two groups. In one group, nasal dorsum height reduction was performed with a rasp, and in the other group, hump reduction was fulfilled with piezosurgery. The patients in both groups were examined after 10, 30, and 90 days of surgery to detect palpebral ecchymosis, asymmetry, bony form, and cartilaginous irregularities of the dorsum.
Results: In the rasp group, two patients with ecchymosis were observed on the 10th day after surgery. Moreover, one patient with dorsal asymmetry, two patients with bony form, and one patient with cartilaginous irregularity in the dorsum were observed in the 3rd month after surgery. In the piezosurgery group, no patient had any complications. However, these differences between the two groups were not statistically significant (P>0.05).
Conclusion: As evidenced by the obtained results, piezosurgery can be used safely for hump reduction.
