Addressing normal anatomy, the sphenoid bone forms the foundation of the central skull base. It forms the floor of the middle cranial fossa, provides structure for the cavernous sinus and a base for the pituitary gland. The shape of the sphenoid bone is bird-like with outstretched wings, being...
Post adenoidectomy can lead to the formation of scar tissue, which in the long run could cause a narrowing of the airways. This event could occur, in particular, if muscle tissue or soft tissue suffered partial damage during the surgical approach.[24] The nasopharyngeal area is the site of ...
Although the anatomy is complex, lesions of the head and neck are relatively easily visualised both by direct vision and by conventional radiology (Fletcher and Jing, 1972; Dodd and Jing, 1977). Furthermore, biopsy within the pharynx and paranasal sinuses is a minor procedure, so that the ...
Anatomy This group contains the malar and the buccofacial nodes. These are superficial nodes surrounding the facial vessels on the external surface of the buccinator muscle. It is bounded superiorly by the inferior edge of the orbit and inferiorly by the inferior border of the mandible. It is ...

Mid-level branch:Most mid-level OARs are primarily soft tissue, which has limited contrast and can be easily confused with other structures with similar intensities and shapes. Hence, we incorporated the anchor predictions into mid-level learning. Specifically, the anchor predictions and the pCT wer...
