About the department

The Department of Adult and Pediatric Oral, Maxillofacial Surgery at the Hannover Medical School offers the full range of services in this field. The priority focuses of the medical facility include dental interventions, particularly various techniques of bone augmentation in the jaw area, implantology, treatment of maxillofacial injuries, maxillofacial benign and malignant neoplasms, inflammatory pathologies, correction of the cleft palate and other congenital and acquired facial defects. The department is a world leader in reconstructive orbital surgery. The department's special feature is the availability of the cutting-edge computer equipment for treatment planning and performance of the operations with the highest accuracy and efficiency. The department is headed by Prof. Dr. med. Nils-Claudius Gellrich.

The department's surgeons have invaluable experience in the treatment of head and neck malignancies. One of the most common diagnoses is oral squamous cell carcinoma. This type of cancer is mostly diagnosed at the advanced stages, which makes its treatment a rather difficult task. To detect the tumor and determine the stage of the pathology, the doctors conduct general clinical examination, computed tomography, magnetic resonance imaging, ultrasound examination, biopsy. If necessary, positron emission tomography can also be carried out. The basis of therapy is the surgical removal of the tumor, including radical resection. All therapeutic procedures meet the guidelines of the German-Austrian-Swiss Working Group on Maxillofacial Tumors (DÖSAK).

Thanks to the use of state-of-the-art surgical techniques, the doctors achieve excellent functional results and provide the patient with a good aesthetic appearance. In advanced types of cancer, surgery can often be often supplemented by radiation therapy and chemotherapy. The decision on a multimodal approach to treatment is made at regular tumor boards individually for each patient. Once treatment is completed, the patient will be prescribed a specially adapted follow-up program. It aims to prevent the disease recurrence.

The department is also proud of its outstanding achievements in reconstructive orbital surgery. Such interventions are performed in the case of orbital injuries and fractures, which can be complicated by eye displacement and negative effect on vision. The reconstructive eye surgeries are complex procedures, which require careful and accurate planning. The state-of-art equipment for computed tomography and digital volume tomography is used for this purpose. When performing surgical treatment, the optimal result is achieved thanks to the use of special titanium implants. There are also alternative methods, which can be applied depending on the patient’s specific clinical situation.

In collaboration with other specialized departments, the specialists perform interventions to correct cleft lip, jaw and palate in children. The department pays special attention to monitoring of changes in the position of teeth and defects caused by bone deficiency in the cleft area. The surgical treatment is followed by regular interdisciplinary consultations for the child and his parents, during which the specialists assess the development of the child and prescribe therapeutic measures, if necessary.
