Endoscopic contralateral transmaxillary approach for pterygoid process osteotomy in total maxillectomy: A technical case report



Endoscopic contralateral transmaxillary approach for pterygoid process osteotomy in total maxillectomy: A technical case report



Auris Nasus Larynx 45(3): 622-625



An approach for total maxillectomy with endoscopic transection of the pterygoid process via the contralateral maxillary sinus is described. In total maxillectomy, the resection of the pterygoid process of the sphenoid is a key step for successful resection. However, a conventional craniofacial approach requires extensive incision in the face, elevation of the lateral cheek flap. Even after elevation of the lateral cheek flap, visualization of this region is not good. An endoscopic approach through the contralateral maxillary sinus improved visualization of the pterygoid process, and osteotomy using a diamond-drilling bar was successfully performed. This technique has the potential to widen the indication for total maxillectomy in malignant neoplasms of the maxillary sinus.
