Conclusion The lacrimal pathway obstruction after external dacryocystorhinotomy can usually be cured by the transnasal endoscopic examination and treatment.
Method The clinical data of 15 cases with chronic dacryocystisis accepted dacryocystorhinostomy through nasal cavity and lacrimal sac were analyzed retrospectively.
There are epiphora,conjunctival hyperemia.Press the area of the dacryocystitis there is mucous or mucopurulent secretion flowing out from the lacrimal punctum.....
In some people, there's also dryness of the affected eye or mouth because the facial nerve innervates the lacrimal, submandibular, and sublingual glands.
The facial nerve also innervates the sublingual and submandibular glands, which secrete saliva, as well as the lacrimal gland which produces tears, and mucous membranes of the nose, mouth, and nasopharynx.
And while all three are secreted from the lacrimal glands in your eye, only the production of emotional tears is controlled by the hypothalamus - an area of your brain that regulates emotional responses.
