THERAPEUTIC APPROACH TO BILATERAL INFRAORBITAL FISTULA IN A DOG: SURGICAL AND MEDICAL TREATMENT – CASE REPORT

Abstract

Infraorbital dental fistula consists of a periapical osteolytic lesion that commonly affects the maxillary fourth premolar in dogs and may present unilaterally or bilaterally. This condition is frequently associated with periodontal disease and infectious processes of dental origin. Diagnosis involves patient history, clinical examination, oral cavity assessment, and complementary imaging examinations, such as skull radiography, which assists in identifying periapical changes and planning treatment. This study aims to report the surgical and medical management of a geriatric patient affected by periodontal disease associated with bilateral infraorbital dental fistula. Following clinical evaluation and complementary examinations, the patient underwent oral prophylaxis, extraction of the right and left maxillary fourth premolars, debridement of the infraorbital lesions, and systemic and topical medication. During postoperative follow-up, favorable clinical progress was observed, with complete healing of the lesions within 25 days. This case highlights the importance of diagnostic imaging, removal of the odontogenic infectious source, and postoperative follow-up for the successful treatment of this condition in dogs.
