nasolacrimal endoscopy

Nasal lacrimal endoscopy is an instrument that detects the obstruction of the nasolacrimal duct. The nasolacrimalduct of the nasolacrimal duct is a membranous duct. The upper part is embedded in the nasolacrimal duct and is closely combined with the periosteum; the lower part is deep in the mucosa of the outer wall of the nasal cavity. The lower portion is open at the front of the outer side wall of the lower nasal passage. If there is a large amount of purulent secretion after bacterial infection, early treatment is needed. Basic Information Specialist Category: Otolaryngology Examination Category: Endoscope Applicable gender: whether men and women apply fasting: not fasting Tips: The fingernails should be cleaned and washed. Normal value Acute dacryocystitis is mostly caused by acute episodes of chronic dacryocystitis, which is related to the decreased resistance of patients, damage, and the virulence of invading bacteria. The skin of the lacrimal sac area has severe red, swollen, hot, painful and other acute inflammatory manifestations. The inflammation can spread to the nasal roots, eyelids and face. Due to local edema, the purulent secretions in the lacrimal sac are not easy to get from the upper and lower tears. Extrusion, severe fever, chills and discomfort. Chronic dacryocystitis in patients with tears and hand pressure in the lacrimal sac area with mucopurulent secretions from the small points of the tears, is an infectious lesion of the eye, must be treated before the operation of the internal eye surgery. Clinical significance Abnormal result Blockage of the nasolacrimal duct can induce acute dacryocystitis, which makes the conjunctival sac secretions a non-bacterial mucus secretion at the beginning. For example, after bacterial infection, there may be a large amount of purulent secretions. Therefore, early treatment is needed. People in need of examination: patients with obstruction of the lacrimal duct or acute dacryocystitis. Precautions Inappropriate crowd: There is no scope for this, and it is unnecessary to check if the eyes are fine. Requirements for examination: symptomatic treatment and treatment according to different causes to remove the cause. Inspection process Traditional treatments for dacryocystitis are often treated with drugs; lacrimal passage or expansion, and dacryocystorhinostomy. At present, there is a tendency to silicone tube lacrimal implantation. Due to the particularity of the implant material, it has good histocompatibility, and can fully and effectively expand the lacrimal canal and nasolacrimal duct, and has great flexibility in leaving time. There is no damage to the normal tissue structure, postoperative treatment is simple and easy, and patients with pain are willing to accept it. However, lacrimal ductation has a variety of procedures and is cumbersome to operate. Not suitable for the crowd Generally there are no people who are not suitable. Adverse reactions and risks Generally no adverse reactions.
