%X BACKGROUND: Medication-related ear canal osteonecrosis (MRECO) is a growing concern linked to prolonged anti-resorptive medication use. Despite primary care providers being key prescribers of these medications, there is limited information about MRECO in primary care literature. This article presents a case of bisphosphonate-induced osteonecrosis of the external auditory canal (EAC), emphasizing the vital role of primary care providers in identifying this rare yet significant side effect of anti-resorptive medication.
UNASSIGNED: A 65-year-old female, on long-term alendronic acid for osteoporosis, presented to primary care with a 2-year history of left-sided ear blockage and itchiness. Despite prolonged topical treatment for ear wax, symptoms persisted, leading to an Otolaryngology referral. Microsuction revealed exposed bone in the left EAC.
METHODS: A computed tomography scan confirmed bony erosion of the left EAC, and in the absence of other osteonecrosis risk factors, bisphosphonate-induced osteonecrosis was diagnosed. Management involved bisphosphonate discontinuation, regular aural toilet, and topical treatment, achieving complete ear canal epithelialisation within 6 months.
CONCLUSIONS: MRECO, a rare complication of anti-resorptive therapy, is anticipated to rise with increasing antiresorptive medication use in the ageing population. Unexplained ear symptoms in those with a history of current or prior anti-resorptive therapy should raise clinical concern, prompting evaluation for exposed bone in the EAC. Raising awareness of MRECO among primary care providers is crucial for early diagnosis and timely management.
