Inclusion criteria
Inclusion criteria: 1. The tumor is located in the deep area of the mouth (gingival region, soft palate, base of the tongue or parapharynx, etc.) or deep maxillofacial area (maxilla, ascending branch of the mandible, zygomatic bone, or skull base-subtemporal fossa, etc.), involving two or more anatomical areas; 2. Underwent CT and MRI examination before surgery, and possessed imaging data in digital imaging and communication in medicine (DICOM) format in two modalities; 3. The scanning range of imaging examination is below the upper boundary of the lower edge of the orbit and below the apex of the lower transorbital area. 4. The tumor is primary or recurrent, with or without pathological diagnosis.
Exclusion criteria
Exclusion criteria: 1. The image shows that the upper and lower teeth are not in the median position when the patient undergoes imaging examination, and the position relationship between the tumor and the surrounding anatomical structure of the patient may be offset between different images due to occlusal instability; 2. The interval between the two imaging examinations is more than 20 days, in which case the tumor may be deformed between different images due to volume growth.
