tumours may be malignant in 50% of cases.
After creating osteotomy, lacrimal sac
Endoscopic examination of nasal cavities was done for any nasal pathology especially mucosal disease, hypertrophied middle turbinate, nasal polyp, deviated nasal septum and anatomical variations of lacrimal sac
that may produce hindrance during endonasal surgery.
The congenital defects of lacrimal apparatus are congenital absence of lacrimal gland, congenital fistula of lacrimal gland, atresia of the lacrimal punctum, atresia of the canaliculi, mucocele of the lacrimal sac
but most common malformation is congenital blockage of nasolacrimal duct which may be complete or partial and is bilateral in 1/3 of cases.
Transcanalicular DCR is a new procedure involving transcanalicular opening in the lacrimal sac
and the nasal bone passing the nasal mucosa into the nasal cavity using diode laser probe and then insertion of a tube which remains in situ for three months.
Characterization of mucins in human lacrimal sac
and nasolacrimal duct.
Lacrimal fluid drains through the puncta into the lacrimal canaliculi and then into the lacrimal sac
behind the medial canthal tendon.
The excretory portion comprises the drainage system which starts in the lacrimal puncta, followed by the lacrimal canaliculi; lacrimal sac
and nasolacrimal duct (GRAHN & STOREY, 2004).
It's a hard bone and contributes to protection of the lacrimal sac
This can lead to red, swollen tear sacs - the medical term is dacryocystitis, or lacrimal sac
An infection and swelling of the lacrimal sac
, it is treated with antibiotics.
The tear ducts lead to the tear, or lacrimal sac
, and then to the nasal duct.
Any extra fluid flows to a lacrimal sac
near the inner corner of your eye.
External dacryocystorhinostomy involves anastomosing the lacrimal sac
to the nasal mucosa of the middle nasal meatus.
