Diagnostic and Therapeutic Evaluations of Computed Tomography in Three Calves with Unilateral Otitis Media Treated with Ventral Bulla Osteotomy. Vet Sci 2022; 9:vetsci9050218. [PMID: 35622746 PMCID: PMC9145070 DOI: 10.3390/vetsci9050218] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 04/25/2022] [Accepted: 04/27/2022] [Indexed: 02/04/2023] Open
Abstract
This case report describes the clinical utility of computed tomography (CT) in preoperative evaluation of otitis media in three calves, each exhibiting unilateral head tilt and ear droop. Of the three animals examined by CT, right-sided and left-sided involvements of this disease could be diagnosed in two animals and one animal, respectively, as represented by the accumulations of hyperattenuating contents within the extended tympanic bulla. These cases were treated with a ventral bulla osteotomy, which was conducted between the sternothyroid muscle and the omohyoid muscle via an incision made caudally to the area of the thyroid cartilage. The postoperative outcome was satisfactory in one case. However, the remaining two cases showed unsatisfactory outcomes; one calf died on the 10th postoperative day, as it was already seriously ill. The other animal died suddenly during surgery, potentially due to stimulation of the vagus nerve. The use of CT could allow effective visualization of unilateral lesions, proving helpful for the recommendation of surgical intervention. Based on the unfavorable results in two cases, we note that to prevent surgical complications, the clinical applicability of CT such as the creation of severity criteria and development of imaging-assist procedure should be advanced.

Abstract
Two-month-old (Case 1) and one-year-old (Case 2) Japanese Black cattle presented with
bilateral rostral mandibular open fractures. At presentation, the proximal edges of each
fracture were discolored and had a severe stench, indicating necrosis caused by infection.
In both cases, a bilateral rostral mandibulectomy over the symphysis was performed.
Although the tongues of both animals prolapsed post-surgery, they had no significant
problems with eating or drinking. Case 1 showed excellent growth during fattening, and
Case 2 successfully became pregnant and gave birth. Rostral mandibulectomy can be an
effective surgical option for the treatment of cattle with difficulty in internal or
external fixation due to unfavorable necrotic cranial mandibular open fractures.

Abstract
A 10-year-old cat presented for evaluation with a 1-month history of salivation and oral bleeding. A right mandibular mass was palpated and computed tomography examination revealed entire bone proliferation. Mandibular bone biopsy was performed, and histopathological diagnosis was vascular hamartoma. The cat suddenly died on day 140.
