Case 3 - Adenoid cystic carcinoma of left maxillary sinus with metastasis to maxillary division and gasserian ganglion
Case 4 - Recurrent adenoid cystic carcinoma of left submandibular gland with metastasis to left mandibular division and gasserian ganglion
Case 5 - Neurogenic sarcoma of left mandible with metastasis to mandibular division and gasserian ganglion
Case 6 - Recurrent tumor of right lower lip with  metastasis to mandibular division and gasserian ganglion
Case 7 - Melanoma of right cheek with metastasis to maxillary division
