“…With constant advances in instrumentation and techniques, the results of primary and revision endoscopic dacryocystorhinostomy (DCR) are now comparable to those of external approaches 3,4. The use of navigation guidance is quickly gaining foothold in complex endoscopic lacrimal surgeries 5–7. The advantages of navigation guidance include accurate target localization, reduced risk of complications and enhanced safety.…”

PurposeThe aims of this study were to report the preliminary experience of using telescopes, which were enabled for navigation guidance, and their utility in complex endoscopic lacrimal surgeries.MethodsNavigation enabling of the telescope was achieved by using the AxiEM™ malleable neuronavigation shunt stylet. Image-guided dacryolocalization was performed in five patients using the intraoperative image-guided StealthStation™ system in the electromagnetic mode. The “look ahead” protocol software was used to assist the surgeon in assessing the intraoperative geometric location of the endoscope and what lies ahead in real time. All patients underwent navigation-guided powered endoscopic dacryocystorhinostomy. The utility of uninterrupted navigation guidance throughout the surgery with the endoscope as the navigating tool was noted.ResultsIntraoperative geometric localization of the lacrimal sac and the nasolacrimal duct could be easily deciphered. Constant orientation of the lacrimal drainage system and the peri-lacrimal anatomy was possible without the need for repeated point localizations throughout the surgery. The “look ahead” features could accurately alert the surgeon of anatomical structures that exists at 5, 10 and 15 mm in front of the endoscope. Good securing of the shunt stylet with the telescope was found to be essential for constant and accurate navigation.ConclusionNavigation-enabled endoscopes provide the surgeon with the advantage of sustained stereotactic anatomical awareness at all times during the surgery.

AimThe aim of this study was to assess the anatomical accuracy of navigation technology in localizing defined anatomic landmarks within the orbit with respect to type of technology (optical versus electromagnetic systems) and position of the dynamic reference marker on the skull (vertex, temporal, parietal, and mastoid) using in vitro navigation-enabled human skulls. The role of this model as a possible learning tool for anatomicoradiological correlations was also assessed.MethodsComputed tomography (CT) scans were performed on three cadaveric human skulls using the standard image-guidance acquisition protocols. Thirty-five anatomical landmarks were identified for stereotactic navigation using the image-guided StealthStation S7™ in both electromagnetic and optical modes. Three outcome measures studied were accuracy of anatomical localization and its repeatability, comparisons between the electromagnetic and optical modes in assessing radiological accuracy, and the efficacy of dynamic reference frame (DRF) at different locations on the skull.ResultsThe geometric localization of all the identified anatomical landmarks could be achieved accurately. The Cohen’s kappa agreements between the surgeons were found to be perfect (kappa =0.941) at all predetermined points. There was no difference in anatomical localization between the optical and electromagnetic modes (P≤0.001). Precision for radiological identification did not differ with various positions of the DRF. Skulls with intact anatomical details and careful CT image acquisitions were found to be stereotactically useful.ConclusionAccuracy of anatomic localization within the orbit with navigation technology is equal with optical and electromagnetic system. The location of DRF does not affect the accuracy. Navigation-enabled skull models can be potentially useful as teaching tools for achieving the accurate radiological orientation of orbital and periorbital structures.

“…We have discussed how these influence the outcomes in the references. 45,46 Ruchi Goel: In traumatic cases, the nasolacrimal blockage may be only a part of the multiple deformities. Also, the orbital fractures may result in misalignment of bones resulting in difficulty in identifying the anatomical landmarks as well as crowding of the nasal cavity.…”

“…Stereotactic lacrimal surgeries are coming up in a big way, with newer very wide angle endoscopic instruments and techniques and Indians are in the forefront of this advancement! [48][49][50] BASIC SCIENCES: The future of any science lies in molecular biology and serious efforts to study all the potential basic science aspects of lacrimal drainage system are being pursued. A more detailed study of literature would give the readers a glimpse into what the future possibly holds!…”
