Addendum to “The T-shape spreader – An easily constructed instrument for facilitating the sagittal split osteotomy” [Brit. J. Oral Max. Surg. 51 (2013) 81–82]

      The authors of this paper recently received correspondence from Captain RC Sanderson, Retired Consultant Oral and Maxillofacial Surgeon, that the T-shape instrument described in our technical note was first demonstrated to him by Air Commodore TW Negus while he was training at The RAF Hospital, Ely in 1988. The Air Commodore may have designed this as well as several other surgical instruments though it was never published. On behalf of the authors, I would like to thank Captain Sanderson for bringing this information to our attention and apologise for this oversight. We would of course wish to credit Air Commodore Negus if he was responsible for the original design of this useful instrument.

          Since its first description by Trauner and Obwegeser in 1957,1,2 the technique for mandibular bilateral sagittal split osteotomy (BSSO) has been modified in various ways to avoid a bad split – a propagation of the osteotomy in any unfavourable direction, which can occur when converting corticotomy to full osteotomy. Various curved osteotomes and instruments designed to control the direction of fracture include commonly used spreaders or elevators such as the Smith 12 mm ramus separator or Smith curved sagittal split separators (Biomet Microfixation, Jacksonville, USA).
