There are few published data regarding the success rates of cheek tooth (CT) removal by lateral buccotomy in the horse.
A retrospective study of 114 horses admitted to 2 private equine referral hospitals over a 10 year period (1999-2009), which underwent CT removal via a lateral buccotomy.
Hospital records were analysed and details including case details, presenting complaint and results of all diagnostic tests and surgical reports were documented. Information obtained during post operative reassessment was also available for analysis. Long-term follow-up information (>2 months) was obtained for 112 horses.
Short-term complications (<2 months) occurred in 24/77 horses (31%) undergoing exodontia of the maxillary CT and 10/37 horses (27%) involving mandibular CT, with the majority arising from partial wound dehiscence and infection following 16 extractions (47%). All healed well by second intention. Other complications included both temporary (n = 6) and permanent (n = 3) facial nerve paralysis, myositis (n = 4) and the inadvertent establishment of an oroantral fistula (n = 4). One myositis case was subjected to euthanasia 24 h post operatively. Five horses had persistent sinusitis following surgery due to dental remnants (n = 2) and excessive packing material (n = 1) found in the sinuses. No inciting cause could be found in the remaining 2 horses. One further horse suffered a fatal cardiac arrest at induction of anaesthesia. Of all horses, 92% operated on had returned to their previous level of work after >2 months with no complications.
Horses with CT removal by a lateral buccotomy have a reasonable prognosis for long-term outcome.
Performing a lateral buccotomy is a justified treatment alternative for the surgical removal of equine CT following unsuccessful attempts by standing oral extraction, offering advantages over alternatives such as retropulsion, endodontic therapy and periapical curettage.
关于马通过颊侧切开术拔除颊齿（CT）的成功率，发表的数据很少。
对 2009 年期间（1999-2009 年）在 2 家私人马科转诊医院接受颊侧切开术拔除 CT 的 114 匹马进行回顾性研究。
分析医院记录，记录病例详情、主诉以及所有诊断性检查和手术报告的结果。还可以获得术后重新评估期间获得的信息。112 匹马获得了>2 个月的长期随访信息。
上颌 CT 拔除术 77 例中有 24 例（31%）和下颌 CT 拔除术 37 例中有 10 例（27%）在<2 个月内发生短期并发症，大多数并发症是由于 16 例拔牙后部分伤口裂开和感染所致。所有病例均通过二期愈合良好。其他并发症包括暂时性（n=6）和永久性（n=3）面神经瘫痪、肌炎（n=4）和意外建立口-鼻腔瘘（n=4）。1 例肌炎病例术后 24 小时内被安乐死。由于窦内遗留的牙齿残根（n=2）和过多的填塞材料（n=1），5 例术后出现持续性窦炎。在其余 2 例马中未发现引发原因。另 1 匹马在麻醉诱导时发生致命性心脏骤停。所有手术后>2 个月无并发症且恢复到术前活动水平的马占 92%。
通过颊侧切开术拔除 CT 的马预后长期结果合理。
对于经站立口腔拔牙失败的马，通过颊侧切开术拔除 CT 是一种合理的治疗选择，优于后退、根管治疗和根尖刮除等替代方法。
