Endonasal Dacryocystorhinostomy
Conditions
Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evolution of the stoma size | Month 12 | Measurement of the stoma size by endonasal photography |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Mucous orifices size | Month 2 | Measurement of the osteotomy orifices size from photography |
| Ratio of patients for whom the operation is a success | Month 12 | A success corresponds to the complete disappearance of epiphora symptomatology, on the contrary, a failure equals to the persistence of tearing or a recurrence of dacryocystitis |
