Endoscopic para-pharyngeal space tumor excision method

Abstract

The invention discloses an endoscopic para-pharyngeal space tumor excision method. The method comprises the following steps of dividing a conical structure of a para-pharyngeal space into two parts, namely an upper para-pharyngeal space and a lower para-pharyngeal space by taking a hard palate level as a boundary, and dividing the upper para-pharyngeal space into a front inner sub-region, a frontouter sub-region, a rear inner sub-region and a rear outer sub-region along a sagittal plane and a coronal plane by an axis of the internal carotid artery, and before an operation, selecting a properoperation approach according to the sub-region where the tumor body is located. The method has the beneficial effects that different endoscopic surgery approaches are selected according to the sub-region where the tumor body is located before the operation, the endoscopic surgery mode is adopted, the surgery view is fully exposed, intraoperative bleeding and surgical injuries are reduced, the occurrence and recurrence rate of postoperative complications is reduced, and the prognosis of a patient is improved.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to an endoscopic hypopharyngeal space tumor resection method. Background technique [0002] Endoscope: a detection instrument that integrates traditional optics, human engineering precision machinery, modern electronic data software, etc. With image sensing, optical lens source lighting mechanism. It can enter the human body through the hole for relevant examination and surgical treatment. Parapharyngeal space: An anatomical biological tissue space of the human body, located on both sides of the pharynx, one on the left and one on the left, shaped like an upside-down vertebral body, with the base of the cone on the top and the tip of the cone downward, starting from the base of the skull at the top and reaching the tongue at the bottom Bone, located between the medial pterygoid muscle, the deep part of the parotid gland, and the lateral wall of the pharynx. It is an important anat...
