Dental sectioning for intraoral equine cheek teeth extractions: 29 cases.

The objectives of this retrospective study were to describe cheek teeth extraction by the sectioning technique, the decision making to use this technique and its potentially associated complications. Sectioning for dental extraction purpose was used in 29/461 (6.3%) of cases. Oro-sinusal fistula was the main post-operative complication, with 4/29 (13.7%) cases developing a macroscopic communication between the alveolus of the tooth extracted and the adjacent sinus compartment. All teeth where sectioning was attempted were successfully extracted. Sectioning for dental extraction appears to be a safe technique that can be used instead of or in addition too other minimal invasive cheek teeth extraction techniques. Thorough preoperative planning including oroscopic examination and medical imaging modalities are required to help in decision making, as well as excellent sedation and analgesia and horse compliance.

Efficient primary surgical treatment of equine infectious sinusitis reduces postoperative aftercare and increases outcome results: a retrospective study of 130 cases.

OBJECTIVE: To document the long-term outcome of surgically treated primary and dental-related sinusitis in horses and to describe a simple protocol for postoperative management. METHODS: All surgically treated sinusitis cases referred between January 2016 and June 2022 were reviewed. Cases diagnosed with primary and dental-related sinusitis and with a follow-up of at least 6 months after hospital discharge were included. Cases with other sinus pathology were excluded. RESULTS: 130 cases met the inclusion criteria. 104 out of 130 were treated with sinoscopy and 26/130 with sinusotomy. 86 out of 130 cases (66.2%) were diagnosed with a dental pathology as a cause of sinusitis that required tooth extraction. Diagnostics were refined with the help of CT in 55/130 (42%) cases. Short-term complications were encountered in 8/130 (6.2%), and full response after initial treatment was successful for 107/130 cases (82.3%). The mean number of postoperative daily flushes was 3.15, and horses were discharged after a mean hospitalization period of 6.4 days. CLINICAL RELEVANCE: Thorough debridement of sinuses affected by primary or dental-related sinusitis followed by a simple aftercare protocol can lead to a positive long-term outcome.
