Aberrant submaxillary gland tissue presenting as a cyst of the jaw

Static bone cavity in the condylar neck and mandibular notch of the mandible

“…The aetiology of static bone cavities has been the subject of much controversy. [2][3][4][5][6][7][8][9][10][11][12][13] In the present cases, the enhanced linear structure draining to the pterygoid plexus on enhanced CT and enhanced soft tissue in the cavity of the mandibular notch with flow void on MRI suggests the cause to be of vascular origin. Moreover, the enlargement of the cavity over a period of three years suggests that the cause of the cavity formation was similar to a vascular lesion in the accessory foramen as described by Minowa et al 9,11 Only one case of static bone cavity in the condyle on plain radiography has been reported.…”

“…1 Subsequent studies suggested that the formation of aberrant submandibular gland tissue into the mandible might be a possible cause of static bone cavity formation. [2][3][4][5] A recent study reported that static bone cysts may form by dislocation of the submandibular gland. 6 It has also been reported that the static bone cavity consists of submandibular gland, fat tissue, soft tissue and vascular structures.…”

Static bone cavity of the mandible: computed tomography findings with histopathologic correlation

“…Several studies have suggested that static bone cavities are formed by pressure and aberration of the salivary gland tissues (1,6,12,19). Other work has associated the location of the cavities with each of the three salivary glands (4,18,25).…”

“…STAFNE et al first described this type of lesion and believed that they might occur during the early formation of the mandible (21). Subsequent studies have suggested the presence of submandibular gland tissue as being a possible cause of static bone cavity formation (1,6,12,19).…”

Solitary lesion of the mandible resembling a “Stafne cyst” in human archaeologic material from Mokapu, Hawaii

“…Although most of the lesions were confined to the cancellous portion of the bone, many, especially the larger ones, extended externally interrupting the continuity of the inferior border of the mandible, so that on palpation, an indentation could be clearly felt. Microscopically, the contents of many such defects have been found to contain normal salivary gland tissue (2)(3)(4) and the work of SEWARD (5) has indicated that a portion of the submaxillary gland could extend into the defect. Later work has shown that similar bone defects can also occur in the anterior part of the mandible where they are occupied by sublingual salivary gland tissue (6), Since reported evidence of these bone lesions in ancient populations is rare (7-9) the purpose of the current report is to describe an additional isolated occurrence of this bone defect found among the human skeletal remains of early Polynesians from Hawaii.…”
