“…However, the Wrst endonasal DCR technique was proposed by Caldwell [12], and his technique was modiWed by West [13]. Heermann [14] introduced the binocular operating microscope to intranasal lacrimal surgery, and McDonough and Meiring [15] reported the Wrst En-DCR technique using rigid endoscopes in 1989. Although many studies have compared the advantages and limitations of both surgical techniques (Ex-DCR vs. En-DCR), the American Academy of Ophthalmology and the National Institute of Health and Clinical Excellence were recently emphasized that En-DCR accepted as a [16,17].…”

Endoscopic endonasal dacryocystorhinostomy (En-DCR) success can be affected by many factors. In this study, we aimed to determine the effect of chronic inflammation on the surgical outcome of En-DCR. A series of 25 primary En-DCR cases and their lacrimal sac specimens were involved in the study. The surgical outcomes were assessed subjectively (satisfied and unsatisfied) and objectively (successful and unsuccessful). All the specimens were examined for the chronic inflammation related histopathological features (inflammatory cell infiltration, fibrosis and capillary proliferation) and graded according to their severity. Moreover, a "chronic inflammation score" was established to determine the intensity of chronic inflammation using the grade of histopathological features. A quantitative and statistical analysis of histopathological features and chronic inflammation were performed between patients with satisfactory and unsatisfactory outcome; and patients with successful and unsuccessful outcome. The overall success rate according to subjective and objective assessment was 60%. However, 9 of 10 patients with unsatisfactory and/or unsuccessful outcome (90%) had severe chronic inflammation of lacrimal sac. In subjective assessment, inflammatory cell infiltration (p = 0.050), fibrosis (p = 0.037), capillary proliferation (p = 0.007) and chronic inflammation (p = 0.003) had a statistically significant difference between patients with satisfactory and unsatisfactory outcome. In objective assessment, statistically significant differences were detected between patients with successful and unsuccessful outcome when they compared according to inflammatory cell infiltration (p = 0.027), capillary proliferation (p = 0.007) and chronic inflammation (p = 0.003). Chronic inflammation related histopathological features of variable degree may have a role on En-DCR outcome. Chronic inflammatory score can be used as an indicator of En-DCR success.

The development of modern endonasal sinus surgery is fundamentally based on the introduction of optical instrumentation. Endoscopes and microscopes are commonly used in such surgery. We tested a new combination of a stereoscopic single-channel endoscope with an operating microscope (ENDO-OPMI) for endonasal sinus surgery. This combination of the endoscope and microscope are connected in a way that results in a self-carried stereo-endoscope. To date, the ENDO-OPMI has been evaluated in cadaver studies and 7 cases of endonasal sinus surgery for chronic sinusitis. The trial was used to evaluate the clinical use of the current system and its possibilities for future developments. The ENDO-OPMI was demonstrated to be principally well-suited for endonasal sinus surgery. However, the current technical shortcomings make further developments necessary. Once these are implemented, the system should be superior to the use of an endoscope or microscope alone in endonasal surgery.
