Abstract: Background: Rhinoplasty osteotomes can be sharpened in various ways: professional sharpening or hand sharpening using whetstones or rotary powered devices. Objective: To compare the effectiveness of sharpening osteotomes using various sharpening methods with that of professional sharpening as measured by a custom edge tester. Materials and Methods: We performed repeated serial osteotome impacts on bovine femoral cortical bone. These dull osteotomes were sharpened using preidentified sharpening techniques. Edge morphology was evaluated. Sharpness was tested using a custom mechanical testing platform. Optimized sharpness was achieved with a whetstone sharpening method wherein the osteotome is flipped after every stroke. Results: Seven distinct sharpening methods were tested for sharpness five times each to determine the optimal sharpening method versus professional sharpening (control). The two sharpening methods, 5 (5.51 ± 0.32) and 6 (5.55 ± 0.32), that used this flipping technique were significantly sharper than other methods. Methods 5 ( p = 1.0) and 6 ( p = 1.0) were the only methods that were not significantly different from control. Conclusion: Single stroke with successively alternating surfaces created the sharpest blades that achieved results similar to professional sharpening.
