endoscopic sinus surgery

The use of nasal endoscopes and special surgical instruments for sinus surgery was initiated in the early 1970s by the Austrian rhinologist Messerklinger and is therefore also known as the Messerklinger Technique (MT). Treatment of diseases: sinusitis and nasal polyps Indication Widely used in the treatment of chronic sinusitis, nasal polyps, nosebleeds, hypertrophic rhinitis, nasal septum deformity, sinus cysts, congenital posterior nostril atresia, nasal sinus foreign body, benign tumor resection and some limited malignant tumor resection. Preoperative preparation 1. Cut the nose hair and shave the beard on the day before surgery. 2. A small amount of food can be eaten before local anesthesia. General anesthesia is used to inform patients to fast water 8 hours before surgery. 3. Explain the name, purpose, and anesthesia of the operation to the patient, understand the patient's psychological activities, and solve the psychological problems in a timely manner. 4. T, P, and R were detected 3 times a day before surgery and recorded. Surgical procedure 1. Messerklinger This procedure is a anterior-posterior procedure. It is the most commonly used procedure. The basic procedure is to first remove the uncinate process, and then open the stenosis from the anterior to the posterior, remove the sinus sinus after the opening of the middle nasal methyl plate, and open the sphenoid sinus. Excision of the nasal valve to enlarge the natural mouth of the maxillary sinus and open the crypt. This can be done after the above procedure is completed, or it can be interspersed in the middle of the above procedure. 2. Wigand procedure This procedure is a post-forward procedure. The basic procedure is to first remove the sphenoid sinus in the posterior part of the middle turbinate, and then remove the sphenoid sinus from the anterior wall of the sphenoid sinus, and then open the posterior anterior and posterior ethmoid sinus, and finally open the frontal sinus and resection. The nasal sinus enlarges the natural mouth of the maxillary sinus. Because this procedure sacrifices the middle turbinate and has certain difficulty, it is generally used less. However, if the lesion is limited to the posterior sphenoid sphenoid sinus (isolated sphenoid sinusitis), this procedure can be used. complication Nasal bleeding, nasal adhesions, perforation of the nasal septum, periorbital hemorrhage, periorbital emphysema, intraorbital hematoma, intraorbital infection, intraorbital inflammatory pseudotumor, internal rectus injury, nasolacrimal duct injury, blind cerebrospinal fluid rhinorrhea, meningitis , brain abscess, intracranial hemorrhage, internal carotid artery or cavernous sinus injury.
