title: Transcannular maxillary antral biopsy with Tru-Cut needle.
abstract: A Transcannular Tru-Cut needle maxillary antral biopsy technique, which has been devised as an out-patient procedure to speed up histological diagnosis in antral disease, is here described. A trial carried out with this technique shows that the histological diagnosis reached from such biopsy specimens compares favourably with that reached from specimens taken through an intranasal antrostomy.
