Suture needles can break when they are used to suture the oral mucosa, especially if they have been bent or if excessive force is applied. Several retrieval modalities have been discussed in the literature; these have focused mainly on locating the needle. Although the segment often is found and removed by the surgeon during the procedure, more extensive procedures and paraclinical diagnostics may be necessary. This article presents a case in which a lost suture needle was located using a cone beam computed tomography scan and retrieved via surgery.
