A rational approach to the surgical removal of a root from the antrum is important. Some surgeons prefer the alveolar approach while others prefer the Caldwell-Luc operation. A case is presented where the palatal root tip of the left upper first molar was removed from the maxillary sinus by the Caldwell-Luc approach with simultaneous closure of the oro-antral fistula resulting from dental extraction. A fibreoptic light probe was used. The advantages and disadvantages as well as how to avoid the common complications of this surgical technique are discussed. A good result was achieved with successful removal of the root and no loss of sensibility of the teeth and/or gum for this case.
