[Incision of the third molar in the Netherlands. Incision tech-niques for the removal of impacted third molars in the mandible.].

Various incision techniques to remove impacted third molars in the mandible have been described, for example, the flap incision, the envelope incision, the distal incision and the modified envelope incision. The aim of this study was to record the incision techniques used by oral and maxillofacial surgeons in the Netherlands for the removal of impacted third molars in the mandible. All members of the Dutch Association of Oral and Maxillofacial Surgery (NVMKA) received a questionnaire. In this questionnaire, the surgeons specified their standard incision technique for the removal of, respectively, mesially impacted, upright, or distally impacted mandibular third molars. Of the 323 questionnaires sent, 172 were returned (53,3% response rate). The flap incision and the distal incision were the most frequently used incisions by oral and maxillofacial surgeons (including residents) in the Netherlands. The academic centre seems to have a lasting impact on the preferred way of removing an impacted third molar. It also seems that an oral and maxillofacial surgeon more frequently removes a third molar in the mandible from a sitting position than a resident.
