“…BACKGROUND: Ganglioneuromas (GN) are rare, benign tumors derived from neural crest cells. They are in the same family of neuroblastic tumors that includes the intermediate ganglioneuroblastoma (GNB) and the malignant neuroblastoma (NB), each of which carries a different prognosis based on tumor histopathology. …”

These malformations are the result of the downregulation of genes of the head program together with the abnormal induction of trunk program genes. …”

“…Introduction It is generally agreed that tooth extraction may lead to maxillary sinus pneumatization, resulting in a union between the sinus floor and the crest of the remaining bone in extreme cases. Studies that compared pre- and postextraction radiographs suggest that maxillary sinus pneumatization may occur after posterior tooth extractions. …”
