Objective—To evaluate long-term response of cats with stomatitis to tooth extraction.
Design—Retrospective case series.
Animals—95 cats with stomatitis.
Procedures—Medical records of cats with stomatitis that was treated with tooth extraction during a 14-year period were reviewed. Demographic information and diagnostic results were recorded as well as surgical procedure, including full-mouth extraction (FME) versus partial-mouth extraction (PME), and specifics of medical management. Patients were categorized according to response to treatment.
Results—Median postoperative follow-up time was 231 days (range, 33 to 2,655 days). Of 95 cats, 6 (6.3%) had no improvement and 25 (26.3%) had little improvement in stomatitis following tooth extraction and extended medical management (EMM). Following tooth extraction, 37 (39.0%) cats had substantial clinical improvement and 27 (28.4%) cats had complete resolution of stomatitis; of these 64 cats, 44 (68.8%) required EMM for a finite period to achieve positive outcomes. Extent of tooth extraction (PME vs FME) was not associated with overall response to treatment. At initial recheck examination, a better long-term response to tooth extraction was observed in patients with resolution of abnormal behavior (OR, 7.2), decrease in oral inflammation (OR, 3.5), and lack of need for follow-up medical management with antimicrobials (OR, 3.7).
Conclusions and Clinical Relevance—Extraction of teeth in areas of oral inflammation provided substantial improvement or complete resolution of stomatitis in more than two-thirds of affected cats. Full-mouth extraction did not appear to provide additional benefit over PME. Most cats with stomatitis may require EMM to achieve substantial clinical improvement or complete resolution.

CASE DESCRIPTION A 1-year-old reticulated python (Python reticulatus) was evaluated because of a 2-week history of wheezing and hissing.
CLINICAL FINDINGS Rostral facial cellulitis and deep gingival pockets associated with missing rostral maxillary teeth were evident. Tissues of the nares were swollen, resulting in an audible wheeze during respiration. Multiple scars and superficial facial wounds attributed to biting by live prey were apparent. Radiographic examination revealed bilateral, focal, rostral maxillary osteomyelitis.
TREATMENT AND OUTCOME Wound irrigation, antimicrobials, and anti-inflammatory drug treatment resulted in reduced cellulitis. A 3-week regimen that included empirical antimicrobial treatment and improved husbandry resulted in resolution of the respiratory sounds and partial healing of bite wounds, but radiographic evaluation revealed progressive maxillary osteomyelitis. Microbial culture of blood yielded scant gram-positive cocci and Bacillus spp, which were suspected sample contaminants. Bilateral partial maxillectomies were performed; microbial culture and histologic examination of resected bone confirmed osteomyelitis with gram-positive cocci. Treatment with trimethoprim-sulfamethoxazole was initiated on the basis of microbial susceptibility tests. Four months later, follow-up radiography revealed premaxillary osteomyelitis; surgery was declined, and treatment with trimethoprim-sulfamethoxazole was reinstituted. Eight months after surgery, the patient was reevaluated because of recurrent clinical signs; premaxillectomy was performed, and treatment with trimethoprim-sulfamethoxazole was prescribed on the basis of microbial culture of bone and microbial susceptibility testing. Resolution of osteomyelitis was confirmed by CT 11 months after the initial surgery.
CONCLUSIONS AND CLINICAL RELEVANCE Focal maxillectomies and premaxillectomy were successfully performed in a large python. Surgical management and appropriate antimicrobial treatment resulted in a good outcome.
