Major vascular anomalies are rare. An aberrant internal carotid artery needs no further elaboration. A persistent stapedial artery may run from the facial canal between the stapedial crura. This may obstruct safe access and cause troublesome bleeding. There are reports of safely dividing smaller vessels and proceeding with surgery. Anatomical accounts of the stapedial artery giving segmental supply to the facial nerve and even brainstem are noteworthy for the brave contemplating dividing larger vessels.

The inclusion criteria were met in 47 ears with surgically confirmed otosclerosis in 41 patients. Twenty patients were male, and 21 patients were female. The patients’ ages ranged from 16 to 65 years (mean 41.1 ± 11.6 years). The CT imaging data sets were reviewed by a neuroradiologist and an otolaryngologist. The image analysis by both the neuroradiologist and otolaryngologist detected otospongiotic changes in 36 ears, corresponding to a sensitivity of 76.5%. The absolute interobserver agreement was 86%, with good interobserver reliability (Cohen’s k-coefficient = 0.76). The neuroradiologist’s image reading was selected as the gold standard for further group analysis. In all 36 CT-positive ears, otosclerotic foci were observed in the antefenestral region (fenestral otosclerosis). Among those 36 ‘CT-positive’ ears, five ears (13.8%) showed additional signs of retrofenestral (cochlear) otosclerosis. No temporal bones showed an enlarged vestibular aqueduct, persistent stapedial artery, or an aberrant internal carotid artery.
