Tooth Root in the Maxillary Sinus

October 5, 2015

Sinus Pain after Dental Work • Xray of the Week

 

The accidental displacement of a root into the maxillary sinus is a recognized complication of exodontia. Such roots should normally be removed early rather than late in order to minimize the likelihood of maxillary sinus complications. In some cases, the sinus cavity can be irrigated with saline (antral lavage) and the tooth fragment may be brought back to the site of the opening through which it entered the sinus, and may be retrievable. At other times, a window must be made into the sinus in the Canine fossa--a procedure referred to as "Caldwell-Luc". A root left within the maxillary sinus may, on occasion, pass spontaneously into the nose.
