Displacement of a (part of a) radix or in some cases a part of a tooth into the floor of the mouth can occur during the extraction of a tooth in the mandibula. Possible causes of this are a lingual perforation of the radices or an inappropriate surgical technique. Leaving a fragment in situ in the floor of the mouth can lead to pain, swelling and trismus as a result of infection and/or spontaneous displacement of the fragment. We advise that the tooth or radix be removed as soon as possible. When experience is lacking in the removal of a tooth or radix from the floor of the mouth it is sensible to refer the patient to an oral surgeon. We also advise prescribing antibiotics in order to prevent infection.

Specimen-driven intraoperative assessment of the resection margins provides immediate feedback if an additional excision is needed. However, relocation of an inadequate margin in the wound bed has shown to be difficult. The objective of this study is to assess a reliable method for accurate relocation of inadequate tumor resection margins in the wound bed after intraoperative assessment of the specimen.

Relocation of inadequate resection margins in the wound bed during oral cavity oncological surgery: A feasibility study.

Depth of invasion (DOI) is the most important predictor for lymph node metastasis (LNM) in early stage (T1-T2) oral cancer. The aim of this study is to validate the cut-off value of 4 mm on which the decision to perform an Elective Neck Dissection (END) is made.
