Lacrimal drainage system obstruction: management and results obtained in 70 patients

Nasolacrimal Duct Obstruction after Zygoma Fracture Reduction with Inferior Orbital Margin Fixation

“…1 Transantral ethmoidal orbital decompression in patients having dysthyroid ophthalmopathy can also cause epiphora in many cases. 3 Kohn et al 4 have reported a case of lacrimal obstruction which developed due to migration of implant 32 months after repair of orbital floor fracture.…”

“…Obstruction of lacrimal passages is a well recognized complication of midfacial fractures involving the maxilla, lacrimal bone and ethmoids. 1,2 Although canaliculi are the most commonly injured structures, lacrimal sac and the nasolacrimal duct may also get involved in fractures of maxilla, nasal bones, ethmoids and orbits.…”

Profile of Trauma-related Residual Periorbital Deformities in Indian Children

“…Midfacial trauma, leading to anatomical disruption of the lacrimal drainage system, mainly lacrimal duct obstruction [10] and medial canthal soft tissue injuries, was predominantly observed. In a study on orbital injuries, 32% had involvement of naso-ethmoidal region, 50% of the zygomatic complex and 28% frontal region [8].The success rate of intubation DCR was 69% in the present study and most of the studies had shown similar success rate [10]. In the majority of cases with mild to moderate degree of deformities, we could achieve a satisfactory function of the ocular adnexae and adequate cosmetic repair of the soft tissue injuries.…”

Proximal Lacrimal Obstruction – A Review

“…12 Other thermal injuries to the face will have similar effects. Traumatic injury to the proximal nasolacrimal apparatus is more common in men.…”
