    DCR: When You Start,Do It Right !!

    Introduction: Dacryocystorhinostomy (DCR) is a procedure wherein an alternate passage is created between the lacrimal sac and nasal mucosa through a bony ostium, bypassing the normal lacrimal pathway. Indications: 1. Persistent congenital lacrimal duct obstruction unresponsive to conservative management. 2. Primary acquired nasolacrimal duct obstruction (PANDO). 3. Secondary acquired nasolacrimal duct obstruction (SALDO). Types: DCR can be classified as either external or internal. In external DCR the bone of lacrimal sac fossa is accessed through a cutaneous incision over the medial canthus. In internal DCR the normal openings around the lacrimal outflow system ( puncta, canaliculus, nasal cavity) are utilized to create the passage between the lacrimal sac and nasal cavity, without any skin incision. Internal DCR is most commonly performed through an endonasal approach and can be performed by using roungers, drills and even lasers. Endonasal DCR s can be performed either under endosco

    The Lacrimal Apparatus

    Development of the lacrimal secretory apparatus: The lacrimal gland develops from solid ectodermal buds in the anterior superolateral part of the orbit. The gland does not start functioning fully until approximately 6 weeks after birth. Newborn infants do not produce tears while crying. Development of the lacrimal excretory system: The Nasolacrimal duct opens in the inferior meatus of the nose. Failure of the caudal end to canalize at birth results in congenital nasolacrimal duct obstruction, which resolves spontaneously in the majority of cases within 4-6 weeks of birth. Anatomy of the lacrimal system: The lacrimal secretory apparatus Tears are secreted by the main and accessory lacrimal glands. The main lacrimal gland is located in the lacrimal gland fossa in the superotemporal quadrant of the orbit. The lacrimal gland has two lobes, the larger almond-shaped orbital, and the smaller palpebral lobe. These lobes are divided by the lateral horn of the levator aponeurosis. The palpebral
