Below are some of the lectures at the EVDF.
Total mandibulectomy in a dog is time consuming procedure, requires skills and carries number of possible complications. Such radical procedure is indicated in mandibular tumors when the tumor location dictates margin section. Challenging part of the procedure is removal of the caudal part due to difficulties with manouvring, limited access and strong muscular attachment to caudal madibular structures.
In patients with tumors located in the area of alveolar bone, removing entire organ might not be necessary and still can fulfill important requirement for clean surgical margins. For those patients the author proposes subtotal mandibulectomy with ramus mandible left non resected.
Initial phase of the procedure is proceeded like in total mandibulectomy till reaching the caudal portion of mandible. Then the ostectomy dividing ramus from body of mandible is performed along the horizontal line parallel to mandibular dentition or slightly caudoventral.
Described technique was applied in 25 dogs 17 male (8 castrated), 8 female spayed. Mean age was 9,76yrs (old and mean bodyweight 30,36kg.
Time of subtotal mandibulectomy procedure from the first cut to the last placed suture excluding preparations and lymphnodes resection was between 43 to 75 minutes (mean) 57,84 . The mean total mandibulectomy time performed by the author adequately measured was between 62-80 minutes (mean 72,66)
Compared to total mandibulectomy time of the modified procedure is shorter.
