To describe a surgical technique for excision of minimally invasive mandibular tumors at the level of the premolar and molar teeth, and report outcome in 7 dogs that had mandibular rim excision.
Case series.
Dogs (n=7) with a mandibular tumor at the level of the premolar and molar teeth.
Using an intraoral approach to the mandible, buccal, and lingual mucosal incisions are made to obtain a 10 mm clean margin beyond neoplastic tissue. After subperiosteal soft tissue elevation, a curvilinear rim mandibulectomy is performed, leaving the mandibular canal and ventral cortex intact, followed by osteoplasty. The remaining attached gingiva and alveolar mucosa are sutured over the bony defect.
Seven dogs were treated (1997-2008) for odontogenic and early malignant neoplasms involving the mandible by mandibular rim excision. All dogs had healed, healthy gingival covering over the surgical defect, very good postoperative function, and good quality of life.
Mandibular rim excision, with preservation of the ventral cortex and mandibular canal content, can be a good option for treatment of early odontogenic and malignant lesions of the mandible in medium to large breed dogs.
In medium to large dogs with minimally invasive mandibular neoplasia, mandibular rim excision should be considered as a viable surgical option.
描述一种用于切除前磨牙和磨牙水平的微创下颌骨肿瘤的手术技术，并报告7只接受下颌骨边缘切除的犬的治疗结果。
病例系列。
患有前磨牙和磨牙水平下颌骨肿瘤的犬（n = 7）。
采用经口入路至下颌骨，制作颊侧和舌侧黏膜切口，以在肿瘤组织外获得10毫米的安全切缘。在骨膜下软组织掀起后，进行曲线形边缘下颌骨切除术，保留下颌管和腹侧皮质完整，随后进行骨成形术。将剩余附着的牙龈和牙槽黏膜缝合覆盖在骨缺损处。
7只犬（1997 - 2008年）因涉及下颌骨的牙源性和早期恶性肿瘤接受了下颌骨边缘切除治疗。所有犬的手术缺损处牙龈愈合良好、健康，术后功能非常好，生活质量良好。
保留腹侧皮质和下颌管内容物的下颌骨边缘切除，对于治疗中大型犬的下颌骨早期牙源性和恶性病变可能是一个不错的选择。
对于患有微创下颌骨肿瘤的中大型犬，应考虑将下颌骨边缘切除作为一种可行的手术选择。
