Transpalatal distraction--state of the art for the individual management of transverse maxillary deficiency--a review of 50 consecutive cases.

Transpalatal distraction has been established as a technique for surgical assisted rapid palatal/maxillary expansion (SARPE/SARME) in order to correct transverse maxillary deficiency. From 2007 until 2013 bone borne transpalatal distraction devices have been inserted in 50 patients affected by transverse maxillary deficiency and transpalatal distraction has been performed by the same surgical team. Patient records were retrospectively evaluated after ending of the active distraction phase with respect to indication, achieved expansion, additional procedures and side effects. In all cases the existing transverse maxillary deficiency was corrected by means of transpalatal distraction according to the individual needs. No complications were observed that interfered with that therapeutic aim. Evaluation of the records showed a wide variance of parameters which impedes evidence based statements. According to that series transpalatal distraction is a safe, powerful and reliable procedure and can be recommended as a state of the art procedure for the individually adapted correction of transverse maxillary deficiency if well known parameters of distraction are respected.
