Skull base surgery is a matter of trust.

Dr. Stefan Maas

Dear patients,
dear colleagues,

HEKA Skull Base Surgery is comprised of the Clinic for Otorhinolaryngology at the Bad Hersfeld Clinic, the doctors of the Rhino-Oto-Center, the attending otorhinolaryngology physicians of the Elisabeth Hospital in Kassel, and the North Hesse Institute for Pathology.

With this joint website, each of these independent health care service providers aims to provide information regarding the diagnosis, treatment and removal of tumors of the skull base, the cerebellopontine angle, the orbit and the optic nerve. Moreover, these service providers are available to serve as your attending physicians.

You will profit from the interdisciplinary collaboration, many years of experience and the constant exchange of information among the physicians involved.

In accordance with qualified diagnostics, whether surgery is necessary is reviewed, and alternative therapy options are considered.

Surgery is not a suitable therapy for every patient. However, if surgery does prove necessary, gentle methods which preserve function are applied to facilitate tumor removal.

Do you have any questions? The HEKA physicians can answer them.

Peter Issing and Stefan Maas


Meningioma are benign tumors of the cerebral membrane. In this patient, the meningioma had grown from the neurocranium into the facial skull and was pressing against the optic nerves. Therefore, additional decompression surgery (opticus decompression) was deemed necessary to improve visual acuity.

Glomus tumor

Blood vessel imaging shows a glomus tumor (paraganglioma) of the lateral skull base. Complete and safe tumor removal would not have been possible without displacing the facial nerve. Therefore, the tumor is removed via an infratemporal fossa approach Type A (Fisch approach). In this way, the tumor was removed while simultaneously maintaining the function of the facial nerve.

Acoustic neurinoma

Acoustic neurinomas or more precisely vestibular schwannomas are tumors localized in the cerebellopontine angle. In this patient, it was possible to remove the tumor via an otologic or otorhinolaryngologic surgical approach. The image (magnetic resonance tomography) shows the localization of the tumor in the cerebellopontine angle.


This is an MRI image of a juvenile angiofibroma which was endoscopically removed through the nostrils without making an incision from the outside. There was no measurable loss of blood, and the patient already insisted on being discharged one day after surgery because he felt so well.

Have you been diagnosed with a tumor of the head?

We would be pleased to consult you.
