Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <sec> <title>Objectives</title> <p>Long-term retained foreign bodies in the human body have been reported across many specialties, but relatively few exist in the ENT literature.</p> </sec> <sec> <title>Patients</title> <p>We present a case report of a patient with a broken dental needle fragment in the posterior oral cavity with subsequent migration to the cochlea over the course of 4 years, eventually leading to hearing loss. CT scan and middle ear exploration demonstrated a 4-cm metallic fragment abutting the base of the cochlea, immediately adjacent to the internal carotid artery.</p> </sec> <sec> <title>Interventions</title> <p>The needle segment was removed through an endaural approach without complication.</p> </sec> <sec> <title>Results</title> <p>Postoperatively, the patient had improvements in PTA and speech discrimination, as well as the resolution of chronic otalgia and jaw pain. Imaging, audiologic results, and surgical details and pictures are presented herein.</p> </sec> <sec> <title>Conclusion</title> <p>To our knowledge, based on a thorough PubMed and Google Scholar search, there are no reports of such a foreign body migration from the oral cavity to the skull base.</p> </sec> </abstract>
