Abstract
Background: In rhinoplasty, careful management of the dorsum to achieve a smooth transition from radix to tip is necessary to improve outcomes. Grafts and alloplastic materials were previously used for treatment of dorsal irregularities. Bone dust is one of the leading options that is easily moldable into a paste, reliable and an “orthotopic” option that promotes bony healing across the dorsal bony defect. It is especially useful in closed rhinoplasty, where our visual acuity on the dorsum is relatively reduced.
Objective: We introduce a new tool for rhinoplasty, a minimally invasive bone collector (Micross), as an effective and safe device for harvesting bone dust from the nasal bony pyramid to obtain a camouflage effect on the bony dorsum and for performing surface ostectomy simultaneously.
Material and Method: Eighteen patients were operated for nasal deformity, with closed rhinoplasty between February 2018 and November 2018. In all cases, a minimally invasive bone collector was used for ostectomy and simultaneous harvest of bone dust. The device is externally 5mm in diameter and has a 160o cutting blade on its tip. Its collection chamber-capacity allows harvesting a maximum of 0.25 cc of bone graft at one time.
Results: Comparison of preoperative and postoperative standardized photographs and physical examination revealed no dorsal asymmetry or irregularities in 17 of 18 patients.
Conclusion: The device has the advantage of simultaneous surface ostectomy of nasal bones and graft harvesting and it is practical, safe and efficient for treating dorsal irregularities.
