목적: The study aimed to evaluate the efficacy of using ultrasonic bone aspirator(UBA) in rhinoplasty for hump nose. 방법:Study Design Retrospective chart review.From Oct. 2013. to Nov. 2014. 20 patients underwent humpectomy using the UBA were included. Follow up period was above 3months.Surgical procedure Preoperative photo documentation was taken for all patients in frontal and profile views. Subperiosteal dissection was performed of the overlying nasal bone and the UBA was utilized to sculpture the bony hypertrophy.Post operative dorsal status and complications were estimated. 결과:Post operative dorsal status were significant improved. No individuals experienced over or under correction, delayed healing, infection, soft tissue injury, and deformity of the nasal dorsum. 결론:Application of ultrasonic bone aspirator to rhinoplasty can emulsify the bony spur or hypertrophy with minimal procedure. We can minimize thermal and mechanical injury surrounding soft tissue with continuously irrigation and suction. It is an easy, safe, and effective method for correction of hump nose without complications.
