Extraction of fractured cheek teeth under oral endoscopic guidance in standing horses

Objective: To evaluate a technique for oral extraction of fractured cheek teeth (CT) under oral endoscopic guidance. Study Design: Case series. Animals: Horses (n=30) with fractured CT. Methods: Medical records (April 2007–August 2010) of horses that had standing oral extraction of fractured CT under endoscopic guidance were reviewed. Results: Thirty horses (median age, 11.5 years; range, 5–23 years) had 31 fractured CT (21 maxillary, 10 mandibular) removed. Midline sagittal fractures of maxillary teeth (n=13; 42%) were the most common type, followed by buccal or palatal (10; 32%), and transverse or multiple (5; 16%) fractures. Extraction under endoscopic guidance was successful for 27 (87%) teeth. Median age of the surgical failure group was 7 years (range, 5–8 years), significantly lower than that of the surgical success group (P=.0135, Mann–Whitney U‐test). Conclusions: Endoscopic viewing facilitates instrument use and removal of fractured CT in standing horses.
