Recessive Spherical Headed Silicone Intubation
Dacryocystorhinostomy
The silicone nasolacrimal intubation under nasal endoscopy can restore natural drainage pathway in tears and as an out-patient surgery, it is more simple,cheap and mini-invasive.Recessive Spherical Headed Silicone Intubation is safe,convenient and almost unpainful for no trauma.It has no facial scar and no damage for structure and function of lacrimal duct.Besides,silica gel is non-toxic and nonirritating.Nasal endoscopy handed by otorhinolaryngologist helps intraoperative visualization about anatomy of the nasal cavity,understanding and management of congenital nasolacrimal duct obstruction and is the only method that confirms the correct anatomic position of the catheterization and in real time,avoiding traditionally the blind raking-out wire by the ophthalmologist alone.Compare to the classic DCR,its short therapeutic effects are equal but more convenient and fewer time and money-cost.
Nasolacrimal duct obstruction is common among patients with epiphora,which is seriously affect the quality of life. The treatment principle is to restore or rebuild the lacrimal duct drainage channel. The classic operation type is dacryocystorhinostomy(DCR), which is complex for face-section particularly.After surgery the lacrimal passage can't siphon the tear out physically any more so that it will effect the patients' life.Besides,the operating time,bleeding volume,hospitalization time and total cost for the surgery is higher.
