[Experiences with using the Kozlov trocar for trans-facial removal of maxillary sinus pathology].
BACKGROUND
Pathologies of the maxillary sinus can be reached through a transfacial approach.


METHODS
Therefore a new trocar designed by Kozlov was used to remove pathologic changes in 39 patients using a transcanin fossa puncture approach. A total of 52 procedures were performed and the long-term sequelae were evaluated over a period at least 12 months.


RESULTS
This new trocar allowed in all cases for removal of pathologies within the maxillary sinus with various instruments and even powered instruments under microscopic control. Hypesthesia and numbness of the lip and individual teeth persisted after 11 of 52 procedures without major discomfort for the patient.


CONCLUSIONS
This new instrument has proved to be a useful tool to perform limited sinus procedures under local anaesthesia or as an adjunct of endonasal surgery under general anaesthesia in our hands.
