Summary
Introduction: Progress in medicine depends largely on development in the fields of engineering and computer science. It the nineteen seventies, the invention of computed tomography allowed the possibility of identifying previously unknown pathological situations.
Among actions designed to reduce the risk of complications during PESS, we must include appropriate training for the surgeon and the application of instrumentation adapted specially for children. In the very difficult operative field found in children intraoperative navigation facilitates intervention. The navigation can operate on the optical or electromagnetic principle, and is mainly applied in neurosurgery and ENT.
Aim: To analyse the value of intraoperative navigation during PESS.
Material and method: Ten children underwent PESS with the use of intraoperative navigation in the Paediatric ENT Department of the Warsaw Medical University.
Results: All parameters significantly improved postoperatively compared to the preoperative values. During measurements made in 95% the error of the measurement was 0 mm. In 5% the error of the measurement did not exceed 2 mm. The operative strategy was changed by the introduction of navigation.
Conclusions: 1. Intraoperative navigation is a method considerably facilitating the sense of direction in the operative field. 2. Applying it can reduce the risk of post-operative complications appearing. 3. Error of the measurement reaching 2 mm is a limitation.
