Delayed assessment of the nasolacrimal system at naso-orbito-ethmoid fractures and a modified technique of dacryocystorhinostomy.

Nineteen patients between 8 and 65 years of age (mean age 32) who were treated for naso-orbito-ethmoid area traumas and suffering from epiphora were evaluated. The time after the trauma was at least 4 months. The patients were divided into two groups. The first group consisted of 10 (52.7%) patients who have undergone a surgical procedure for the fractures before. The second group has 9 (47.3%) members who have never been surgically treated after trauma. All of the patients were evaluated with dacryocystography. Obstruction was found to be in the bony nasolacrimal canal in 13 (68.4%) patients. The nasolacrimal canal was intact in six (31.6%) of the patients. Dacryocystorhinostomy (DCR) was essential for five (50%) of the patients in the first group and eight (88.8%) of the patients in the second group. No additional surgical intervention was carried out for nasal deformities of the patients resulting from naso-orbito-ethmoid fractures. Palpebral malposition was present in six (32%) patients. Relief in tear flow was supplied in all patients. Our aim is to compare the outcomes of a modified technique of DCR and incidence of nasolacrimal system injury in patients with naso-orbito-ethmoid fractures and epiphora on whom reduction was or was not carried out. In conclusion, early surgical reduction of naso-orbito-ethmoid fractures should be performed to prevent problems and deformities of the nasolacrimal system.
