      First of all, we would like to thank our colleagues for their kind words regarding our article “Density of the mandibular ramus (cancellous:cortical bone volume ratio) as a predictor of the lingual fracture pattern in bilateral sagittal split osteotomy”.

      Density of the mandibular ramus (cancellous:cortical bone volume ratio) as a predictor of the lingual fracture pattern in bilateral sagittal split osteotomy.
      In this article, we investigated the association between lingual fracture patterns after bilateral sagittal split osteotomy (BSSO) and the cortical and cancellous bone volume in the mandibular ramus. We found that mandibular angles with a relatively small amount of cancellous bone showed more ventral (LSS3) lingual fracture lines (p = 0.043) and more unfavourable fractures (p = 0.143). We thank our colleagues for appreciating these findings as worthy clinical results.
