Professor Dr. med. Thomas Lenarz, Director of the Department of Otorhinolaryngology

Professor Thomas Lenarz, M.D., Ph.D., is a renowned expert in the field of otorhinolaryngology and surgery of the head and neck.

He has built the Department's position as global leader in cochlear implantation. In particular, implantation in children, refinement of surgical techniques and the enhancement of products realised here have resulted in significant advances worldwide.

The Department's scientific work is supported by the Collaborative Research Centre on Biomedical Engineering funded by the German Research Association (DFG). Research outcomes are transformed into advances in modern auditory implants in close collaboration with manufacturers.

Clinical Profile

The Department of Otorhinolaryngology excels through its highly specialised and broad-based range of diagnostic and therapeutic services.

The Department is the world’s leading clinic for the treatment of severe hearing loss in adults and children.
Diagnostic procedures, surgery and postoperative rehabilitation are performed in the world’s largest cochlear implant centre. To date, more than 4,300 patients have received implants here.

The creation of the Hannover Hearing Centre (HZH) gave the Department an ideal environment for performing implants in very young children in particular, and for providing aftercare in close cooperation with their local speech therapists.

The Department has also acquired great expertise in treating patients with moderate hearing loss and providing middle ear implants.

In addition to otosurgery, the Department’s broad therapeutic spectrum also includes endonasal, tumour and skull base surgery at the very highest level.


Key areas of specialisation of Professor Lenarz's Department include:

  • Cochlear implants
  • Auditory brainstem implants
  • Middle ear implants
  • Alternative auditory systems
  • Conventional auditory systems
  • Neonatal hearing screening
  • Skull base surgery (especially acoustic neuroma)
  • Endonasal surgery
  • Tumour surgery
  • Tracheal surgery

The Department's team consists of more than 35 physicians providing top-level expertise in all subdisciplines such as otology, neurotology, oncology, allergology and sleep medicine.

As one of the leading university clinics, the Department is equipped with state-of-the art technical resources.

Scientific Profile

The Department of Otolaryngology of the Hannover Medical School is the international leader in the development of cochlear implants, particularly the electrodes and speech processors for these devices.

Another priority area is refining audiological diagnostic procedures and designing alternative auditory systems.

The Lower Saxony state government supports hearing research as part of its Hearing Excellence Cluster and the Audiology Initiative of Lower Saxony (AIN).
