About the department

The Department of Adult and Pediatric Otolaryngology at the Hannover Medical School offers the full range of modern diagnostic and therapeutic services in this medical focus. Thanks to the world's largest Cochlear Implantation Program, the medical facility is very popular not only in Germany, but also far beyond its borders. The department has 100 beds  at its disposal. It treats about 25,000 outpatients and 6,000 inpatients every year. The department is headed by Prof. Dr. med. Thomas Lenarz.

The main clinical focuses of the department include early detection of hearing loss in children, diagnostics and treatment of neurosensory hearing loss, including tinnitus, the full spectrum of middle ear surgery and installation of partially implanted hearing aids, skull base surgery, including acoustic neuroma treatment, oncosurgery with the use of modern laser and endoscopic interventions, treatment of chronic inflammatory processes of the nose and paranasal sinuses (including allergic reactions), plastic reconstructive interventions, etc.

Of particular interest are the diagnostics and treatment of benign and malignant head and neck diseases (i.e., diseases of the larynx, pharynx and oral cavity, including tumors of the large salivary glands). Therapy is prescribed with due consideration of all the features of a particular clinical situation. The main therapeutic options include surgical treatment, the goal of which is a total removal of the neoplasm and organ function preservation, and combined chemoradiation therapy. In addition, specialists have at their disposal modern surgical techniques, for example, laser surgery, navigation surgery, intraoperative sonography. If desired, the patient may participate in international clinical trials.

It should be noted that the department widely uses innovative laser devices, such as CO2 laser, which is ideal for surgical treatment of soft tissue tumors, neodymium laser (Nd: YAG), which is most often used to treat patients with chronic nasal obstruction, snoring, chronic non-allergic rhinitis, KTP laser, Er: YAG laser.
