| Abstract | OBJECTIVE: The aim of this study was to evaluate the position and the accessibility of labyrinthine windows through the external auditory canal (EAC) by virtual endoscopy based on computed tomographic scan images. STUDY DESIGN: Prospective cross-sectional study. SETTING: Tertiary referral center. PATIENTS: Sixty-three high-resolution temporal bone computed tomographic scans were obtained from 34 adult patients undergoing various otologic procedures. INTERVENTION: Images were analyzed by the virtual endoscopy function included in Osirix (www.osirix-viewer.com). The endoscope was constrained in the EAC. The visible surfaces of target anatomic structures were assessed on multiplanar reconstruction views. RESULTS: The optimal angles of the virtual endoscope position showed a relatively high interindividual variability in the axial plane (64 ± 2.4 degrees for the oval window [OW] and 60 ± 2.5 degrees for the round window [RW]) position, but a low interindividual variation was noted in the coronal plane (107 ± 1.5 degrees for the OW and 112 ± 1.7 degrees for the RW). The RW was accessible in 87% of cases. The OW accessibility could be staged as follows: 1, invisible stapedial superstructure (10% of cases); 2, stapedial posterior crus partly visible (33%); 3, entire posterior crus and pyramid visible (44%); 4, posterior and anterior crus visible (13%). CONCLUSION: Virtual endoscopy through the EAC can evaluate the accessibility of the OW or RW via a transcanal route. This technique seems to be helpful in preplanning minimally invasive procedures by this approach such as cochlear implantation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
