Dacryocystorhinostomy is a commonly performed procedure for nasolacrimal duct obstructions of several etiologies, of which certain post-surgical secondary acquired lacrimal duct obstructions (SALDO) can be very challenging and can be difficult even for the experienced surgeons. This video elucidates the fundamentals of managing post-maxillectomy SALDO that will help the ophthalmology and otolaryngology surgeons. The video illustrates the use of very advanced techniques like stereotactic guidance for localizing lacrimal sacs in patients who do not have any identifiable landmark in the nasal cavity.

Dacryocystorhinostomy is a commonly performed procedure for nasolacrimal duct obstructions of several etiologies, of which syndromic CNLDO are the most difficult. This video elucidates fundamentals of managing obstructed lacrimal drainage system in this rare condition that will help the ophthalmology and otolaryngology surgeons. The video illustrates communicating the ipsilateral lacrimal sac with contralateral nasal cavity, due to the absence of ipsilaterally recognizable nasal structures.

Hearing and visual loss are comorbidities that affect activities of daily living and result in higher mortality rate in an urban population of elderly patients. Patients with age related macular degeneration (ARMD) frequently also have hearing loss, and the combination of hearing and vision loss has been found to be associated with the greatest likelihood of both cognitive and functional decline. The treatment of both has been suggested to decrease the functional decline. Although some forms of hearing loss in the elderly are irreversible, many are reversible. This video covers the unique aspects of aging, vision, and hearing loss in order to appropriately equip the ophthalmologist to refer the patient for evaluation.
