Embodiment Construction

[0013] The present invention will be described in detail below in combination with specific embodiments.

[0014] In the past, the surgical treatment of benign tumors in the parapharyngeal space mainly used open surgical approaches. Road, etc., the most commonly used is through the neck. The transcervical approach is a lateral incision, and it is also the most commonly used and basic operation in the past. If the tumor is too high, it is not suitable. The parapharyngeal space can be divided into two parts: the front part is called the anterior parapharyngeal space; the back part is called the post-parapharyngeal space; the previous division of the parapharyngeal space can guide the decision-making of benign tumors in the parapharyngeal space Due to the lack of flexibility, the operator cannot choose an appropriate surgical approach through the division of the parapharyngeal space. Due to the limitations of the surgical approach and surgical equipment, the surgery will cause ...

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...
