Reviewed by [Christian Espinosa, Founder, Blue Goat Cyber](/authors/christian-espinosa) Last reviewed May 5, 2026 ## Definition ENT devices include cochlear implants (Cochlear, Advanced Bionics, MED-EL), bone-anchored hearing systems, hypoglossal nerve stimulation for sleep apnea (Inspire), sinus balloons, and image-guided sinus and skull-base surgery systems. What the regulation says Regulators classify ENT devices based on their [intended use](/terms/intended-use) and risk. For example, in the US, the FDA regulates these devices under 21 CFR Part 874, Ear, Nose, and Throat Devices. The EU [MDR](/terms/mdr-reporting) also categorizes ENT devices with classification rules outlined in Annex VIII, determining conformity assessment pathways based on invasiveness and contact with the central nervous system. ## What this means in practice Inspire's hypoglossal nerve stimulator opened a large addressable market for moderate-to-severe OSA in [CPAP](/terms/sleep-respiratory-devices)\-intolerant patients. ## Examples - A manufacturer developing a new cochlear implant must navigate Class III regulations in the US, requiring extensive pre-market approval processes and clinical trials. - A company designing a hypoglossal nerve stimulator needs to demonstrate compliance with cybersecurity standards due to its connectivity and potential for patient data access. - A firm introducing a novel sinus balloon dilation system will need to provide clinical evidence demonstrating safety and effectiveness for its intended use. Common pitfalls - • Misclassifying an ENT device can lead to incorrect regulatory pathways and delays in market access. - • Failing to consider the unique cybersecurity risks associated with connected ENT devices can result in patient harm and non-compliance with standards like IEC 81001-5-1. - • Ignoring post-market surveillance requirements for ENT devices can lead to undetected safety issues and regulatory penalties. - • Not adequately addressing usability during the design of ENT devices can result in user error and adverse events. ## Frequently asked questions How are ENT devices classified for regulatory purposes? ENT devices are classified based on their [intended use](/terms/intended-use) and risk to the patient. For instance, in the US, the FDA assigns classifications (Class I, II, or III) under specific product codes, while the EU [MDR](/terms/mdr-reporting) uses rules based on invasiveness and duration of use. What cybersecurity considerations are relevant for connected ENT devices? What kind of clinical data is typically required for ENT devices?
