When conducting an otolaryngology exam, an otologist should test the function of which cranial nerves?

The cranial nerves relevant to an otolaryngology exam primarily include the olfactory nerve and the oculomotor nerve. The olfactory nerve (Cranial Nerve I) is crucial for the sense of smell, which is important during examinations for conditions that might affect olfaction, such as sinus infections or nasal obstructions.

The oculomotor nerve (Cranial Nerve III) is involved in eye movement and controlling most of the eye's movements, including constriction of the pupil and maintaining an open eyelid. In an otolaryngological context, assessing the oculomotor nerve can be relevant when considering conditions that affect eye movements and may also be associated with vestibular disorders that can affect balance and coordination.

In contrast, the function of the other cranial nerves listed in the options has different implications. For example, the trigeminal nerve is mainly responsible for sensation in the face and motor functions such as biting and chewing but is less focused on otolaryngology specifically. The glossopharyngeal and vagus nerves are essential for swallowing and could be tested but are generally not the primary focus during initial otolaryngological exams. Similarly, the accessory and hypoglossal nerves are more
