Fig. 10.2
Raising the flap at the subcutaneous tissue level exposed the lipoma. It is easily excised by staying very close to the tumor
Fig. 10.3
The specimen is removed and sent for histopathological examination, a penrose drain inserted and wound closed

10.3 Excision of Parapharyngeal Neurofibrosarcoma
Fig. 10.9
Incision is marked out for mandibulotomy and inclusion of previous surgical scar for excision with the tumor
Fig. 10.10
After mandibulotomy as described in Chap. 7, the entire tumor is exposed together with the neurovascular structures. The external jugular vein is ligated as it is involved by the tumor. The tumor is found to be arising from the vagus nerve
Fig. 10.11
The tumor is dissected away from the common carotid artery and followed to the angle of the mandible
