Osteoectomy in Rhinoplasty: A New Concept in Nasal Bones Repositioning.

[BACKGROUND] Modern techniques of osteotomy have evolved to take into account the effects of bony repositioning on functional as well as aesthetic outcomes. Although a variety of methods have been described to appropriately mobilize and reposition the bony nasal vault, there is still no single procedure that can successfully manage nasal bones in its entirety.

[MATERIAL AND METHODS] We present the bone chisel scraping osteoectomy technique for lateral and medial osteotomies with the aim of managing nasal bone deformities that can overcome diverse shortcomings of the conventional methods. The new operative method was performed in 184 nasal bone osteoectomies (92 patients, 22 men and 70 women), ranging in age from 18 to 69 years (mean age, 38 years). The functional results were evaluated postoperatively by the Nasal Obstruction Symptom Evaluation scale, a brief and easy to complete validated questionnaire with a final score grading from 0 to 100 at 3 and 6 months postoperatively.

[RESULTS] With this new approach, no functional problems were reported. The mean Nasal Obstruction Symptom Evaluation scale score was 5.3 at 3 months and 1.9 at 6 months. Only 1 primary case was reoperated for open roof deformity. Comparing the results with the previous osteotomy series of the senior author osteoectomy and osteotomy revision rates for inadequate bone mobilization were similar but osteoectomy technique did not create functional problems as the osteotomy technique did.

[CONCLUSIONS] Although this technique prolongs the operating time, it could offer considerable advantages in comparison with the classical techniques using osteotomies and hammer. This is because it offers a greater respect to the nasal respiratory function and gives a much better nasal base width control, resulting in more predictable results, less trauma, and therefore a lower risk of postoperative complications.
