摘要
The aim of this study was to describe alternative methods of tooth removal that were used after oral extraction of cheek teeth (CT) had failed or was deemed impossible. For this purpose a review of medical records was performed. A total of 23 CT were removed in 21 horses, of which 8 (34.8%) were mandibular and 15 (65.2%) were maxillary. For tooth removal minimal invasive buccotomy was performed in 20 cases, solitary repulsion in 1 case, a combination of repulsion and classical lateral buccotomy in 1 case and a combination of repulsion and minimal invasive buccotomy in 1 case. The removal was successful in all cases. Infra- and postoperative complications occurred in 15/23 cases (65.2%). Singular complications happened in 8/15 and two or more complications in 7/15 cases. Complications were divided into intraoperative, short- and long-term as well as surgery related and not surgery related complications. The most common reason to use an alternative procedure to oral extraction was a complete fracture of the clinical crown. In one case traumatic crown impingement made oral extraction impossible. All CT were removed successfully with surgery related complications occurring in 12/23 cases (52.2%). Removal of CT by minimal invasive buccotomy was a useful alternative to repulsion or classical lateral buccotomy in cases of complete fracture or impingement of the crown. If feasible an attempt of oral extraction should first be considered in cases of preexisting partial CT fractures because it is less invasive than any of the alternative approaches. The authors recommend concurrent antimicrobial therapy for horses undergoing minimal invasive buccotomy. Removal of cheek teeth by repulsion or classical buccotomy are indicated in selected cases, and therefor surgeons should also be familiar with these techniques.
