Does the Presence of Impacted Mandibular Third Molars Increase the Risk of Bad Split Incidence During Bilateral Sagittal Split Osteotomy?

Dal Pont vs Hunsuck: Which Technique Can Lead to a Lower Incidence of Bad Split during Bilateral Sagittal Split Osteotomy? A Triple-blind Randomized Clinical Trial

“…Orthognathic surgeries are considered to be the mainstay of treatment for correcting severe jaw discrepancies and malocclusions [1][2][3] . Skeletal class 3 deformities that require surgical intervention seem to be quite frequent among the Iranian population 1,4 . Bilateral Sagittal Split Osteotomy (BSSO) is a wellknown and highly favored technique for correcting mandible growth deformities 1,[3][4][5][6][7][8] .…”

“…This technique was initially introduced by Obwegezer and multiple modifications have been proposed ever since. Dal Pont, Hunsuck, Trauner and Epker modifications are acclaimed BSSO modified techniques in orthognathic surgery 1,[3][4][5][6][7][8][9][10][11][12] . Despite these profound modifications, troublesome complications such as neurosensory disturbances, excessive bleeding, and unfavorable fractures still remain a problem while performing BSSO surgery 1-5, 13, 14 .…”

“…Unfavorable and unanticipated sagittal split osteotomies are referred to as bad split fractures. These fractures can cause unstable surgical fixation, malunion, and infection in the osteotomy site [1][2][3][4][5][12][13][14] . The incidence of unfavorable bad split fractures varies from 1% to 23 % in previously conducted studies 1,4,6,7,12,[15][16][17] .…”

The patient's age, gender, mandibular anatomy, presence of mandibular third molar at surgery as well as the surgeon's expertise are all contributing factors to the occurrence of bad split fractures 1,4,6,7,12,[15][16][17][18] .…”
