RADIOGRAPHIC APPEARANCE OF THE MIDDLE EAR AFTER VENTRALBULLA OSTEOTOMY IN FIVE DOGS WITH OTITIS MEDIA

Radiographs of the middle ear were made in five dogs 60 to 70 months after ventral bulla osteotomy was performed to treat otitis media. The clinical results of surgery were considered satisfactory in four dogs and unsatisfactory in one. In 4 dogs with satisfactory results, radiographs demonstratd complete reformation of the bulla in 3 operated middle ears (3 dogs), with partial bulla reformation in the three middle ears (3 dogs). Radiographs in one dog with unsatisfactory results showed complete bulla reformation with no increase in lumen opacity. The proliferative bony response obilerating the middle ear previously reported in normal dogs after ventral bulla osteotomy was not seen in any of these patients.
