简要总结
Dacryocystorhinostomy (DCR) is a procedure of choice for nasolacrimal duct obstruction. Endonasal procedures for DCR were described as early as 1893 by Caldwell. However, external DCR was practiced more commonly because of better visualization of anatomic features. The miniaturization of surgical instruments and close partnership between ophthalmologist and otorhinolaryngologist had led to a renewal of endonasal approach.
The main objective of the study is to show the evolution of stoma size after endonasal DCR and validate the direct measurement of mucous orifice. It will also allow determining if the stoma evolution size may be a predictive factor for operational effectiveness.
