The objective is to describe the outcome and complications of two cats treated with a hemi plus rostral part contralateral mandibulectomy (1 ½ mandibulectomy) technique for the management of oral squamous cell carcinoma (SCC) with bone infiltration. Mandibulectomy can be performed in cats but unlike canine patients, they may require additional supportive care. Two cats were presented for progressive mass growing on the mandible. Both had bone invasion and were diagnosed with SCC by biopsy examination. The procedure involved a left/right mandibulectomy and the rostral part of the right/left hemimandible caudal to the lower canine tooth (1 ½ mandibulectomy), at least 1 cm far from the macroscopically visible lesions. Both cats had feeding tubes placed. The surgical outcome for one of the two cats was excellent, surpassing 302 days of survival, the other cat did not regain the ability to eat and the owners opted for euthanasia 35 days after surgery. Both histopathological reports confirmed SCC and clean margins. The hypothesis of the study reported here was that 1 ½ mandibulectomy would be effective for control of superficial subcentimetrical, caudal to the canine tooth oral SCC with bone invasion in cats but could also lead to permanent loss of feeding function and compromised quality of life.
