Conclusions
RG is not an uncommon encounter for head and neck surgeons. Its management requires a long-standing experience in the classical transcervical approach that may be sufficient in over 90% of treated cases. Despite a growing body of publications, we still have no shared definition of RG and this continues to bring in heterogeneity in the literature because it hampers a formal comparison and synthesis of the results. We believe that reaching an international consensus among head and neck and endocrine surgeons on the very definition and classification/grading of RG is a priority in order to seriously compare outcomes by data pooling and to increase the evidence in this field. A second priority is the definition of the natural course of this condition since it is likely in the near future that we will face more and more incidental RG as the use of neck imaging is becoming widespread.
