Sudden Unilateral Loss With a Fitting Appointment Already Booked
A 54-year-old man calls to move up his hearing aid follow-up. At his last visit six months ago he had a mild-to-moderate bilateral high-frequency loss consistent with noise exposure from 20 years in manufacturing, and he was fitted bilaterally. He now reports that his right ear 'went dead' about 10 days ago when he woke up, with a loud ringing and a feeling of fullness. He denies dizziness. He has no history of ear surgery or head trauma. He has been using the left device only and says the right device 'does nothing.' He asks whether you can just 'turn the right one up' at the visit.
1. What is your immediate clinical obligation, and what is the reasoning behind the urgency?

The immediate obligation is to recognize this as a possible sudden sensorineural hearing loss and direct him to urgent medical evaluation, ideally same-day, rather than adjusting the device.
Reasoning: a rapid-onset unilateral loss with tinnitus and aural fullness in a patient with a prior stable loss is a red-flag presentation. Sudden sensorineural hearing loss is a medical urgency in which treatment delay is associated with worse hearing outcomes, and the window for intervention is measured in days to a couple of weeks. His 10-day interval already places him inside a time-critical period. The aural fullness and tinnitus are consistent with cochlear involvement and do not require vertigo to be present. Adjusting gain on a device for an ear that may have a new profound loss would at best be useless and at worst mask the urgency.
Action: advise immediate contact with his physician or an otolaryngology/urgent care setting, document the advice and his response, and defer device adjustment until medical clearance and updated audiologic assessment.
2. He asks why you cannot simply increase the right-ear gain today. How do you explain this, and what is your plan for the device once he is medically cleared?
Read the worked answer
Explanation to the patient: the right device is not underperforming because of a setting; the ear's ability to receive sound has changed suddenly. Increasing gain would make sound louder without making it clearer, could cause discomfort, and would delay the evaluation that actually matters. The priority is a medical assessment of the ear, not the device.
Plan after clearance: obtain a current audiogram, including immittance and word recognition, and compare it to the six-month baseline to document the change. If the loss is now profound and word recognition is poor, a right-ear device may provide limited benefit and options such as a CROS/BiCROS arrangement, a contralateral routing strategy, or referral for implant evaluation should be discussed. If hearing recovers partially, re-prescribe and re-verify with real-ear measurement rather than reusing prior settings. Re-counsel on realistic expectations and schedule a shorter follow-up interval.
