Sinus lift approach for the retrieval of root fragments from the maxillary sinus.

A new application of a well-known technique; lateral wall sinus approach, to remove a root fragment from the maxillary sinus with minimal damage to the epithelial lining and anterior face of maxilla is described. The technique presented in this article helps eliminate some of the complications associated with Caldwell Luc procedure while preserving the epithelial lining of the maxillary sinus and bony face of maxilla.
