Two geriatric domestic shorthaired cats (DSH) were treated surgically with a ventral bulla osteotomy and craniectomy for middle ear tumours that invaded the calvarium. Both cats had a history of vestibular disease. One cat had a normal neurological examination. Both cats underwent computed tomographic imaging of the head. After intravenous injection of an iodinated contrast material, one cat had a ring‐enhancing intracranial lesion and the other had a uniform contrast‐enhancing intracranial lesion, which either communicated with the bulla or was associated with bulla osseous lysis/production. One cat had a papillary adenoma and the other had an adenocarcinoma. Both cats had prolonged survivals (630 days; alive and lost to follow‐up at 840 days), which is longer than reported in cats with middle ear neoplasia. Craniectomy, in addition to ventral bulla osteotomy, may be part of the treatment plan for middle ear tumours that invade the calvarium.
