Traumatic incudomalleolar dislocation in a pediatric patient

Abstract

Ossicular chain dislocation with associated conductive hearing loss often warrants surgical intervention such as ossiculoplasty. We present a case report of a 9-year-old male with a left longitudinal temporal bone fracture with associated asymmetric widening of the incudomalleolar joint and secondary hemotympanum. We document the patient's relevant clinical examination, testing, and imaging during clinic visits 2 weeks and 10 weeks after the inciting traumatic event. The patient was improved with no major medical or surgical intervention upon evaluation during the last follow-up visit. We discuss incudomalleolar joint dislocations and benefits of observation despite noting potential ossicular dislocation on imaging following the inciting event.
