The DEUTSCHE STIMMKLINIK is one of the top modern interdisciplinary voice clinics in Europe and specializes nationally and internationally on all aspects of the human voice. The entire spectrum of voice disorders, diseases and functional disturbances of the speaking and the singing voice will be diagnosed including top notch, computer based video systems and electroacoustic voice analysis programs. Diagnostic assessment and therapeutic measures range from minimal voice disturbances to benign mass lesions, paralysis and tumors. The DEUTSCHE STIMMKLINIK provides newest, cutting-edge technology equipment of the latest voice research, abundant space for clinical and pedagogical assessment und training, and last but not least, a highly professional and experienced voice team. The staff covers medicine, SLP – speech language pathology, voice and singing pedagogy, and osteopathy including laryngeal manipulation therapy. A special focus is on treatment of voice disorders in singers, actors, professional voice users, teachers, moderators etc.

Phonosurgical operations for voice improvement is a speciality of Prof. Markus Hess, an internationally well respected phonomicrosurgeon. In the past years, he has performed far more than 5,000 operations on vocal folds.

Voice Therapy

The DEUTSCHE STIMMKLINIK offers a highly professional interdisciplinary team based on longstanding experience of each team member. We are proud that we can offer almost all procedures in an ambulatory setting – and highly appreciated by our patients. The international networking of our staff includes multiple contacts with voice professional all over the world. Our activities are reflected by multiple memberships in national and international societies (CoMeT, DGE-BV, DGHNO, DGPP, DGP, DBL, EAP, EAV, ELS, IALP, IAP, IFOS, PEVOC, VF, UEP etc.).

Patients receive a differentiated and individualized therapeutical consultation and are introduced to conservative strategies of breathing, intonation, resonance use, posture, voice-imaging. Advantages of osteopathy, homeopathy, nature medicine, logopedics and voice coaching up to phonosurgical methods are addressed.

Conservative Therapy

  • Logopedics
  • Breathing therapy
  • Electrostimulation of the larynx (NMES)
  • Osteopathy
  • Laryngeal manipulation after Jacob Lieberman
  • Physiotherapy
  • Manual medicine
  • Tai Chi
  • QiGong
  • Traditional Chinese Medicine (TCM)
  • Vocal pedagogy
  • Voice coaching
  • Voice tuning
  • Vocal arts medicine
  • Professional voice user rehabilitation (singers, actors, moderators, teachers etc.)
  • Choir singing
  • Vocal hygiene program


When all conservative measures do not result in acceptable voice outcome, a phonosurgical procedures might be discussed. If surgery is needed, we assure you that you are in the best hands. We not only perform all kinds of phonosurgical interventions, but we also train colleagues from all over the world since many years how these procedures result in an optimal outcome.

We offer all operative interventions of phonosurgery.

  • Phonomicrosurgery: In general anesthesia, a short and painless procedure where patients are totally asleep, we use microscopes with 25x magnification to remove smallest lesions which are mostly in the order of magnitude of less than one millimeter. This is facilitated with the world’s finest instruments which we gathered to achieve optimal microsurgical results. But not only the removal might be important, but the saving of normal tissues and fibers is of highest priority in phonomicrosurgery. Therefore, removal of small lesions like a polyp, nodule, cyst, pseudocyst, epithelial hyperplasia, Reinke’s edema, scarring, papilloma, hematoma, sulcus vocalis, sulcus vergeture, hemangioma, capillary ectasia, contact granuloma, leukoplakia, biofilm et cetera can take a half an hour or more.
  • Office-based surgery: Since the very beginning of our clinical work we have focused on performing painless in-office procedures in topical spray anesthesia. Excision of lesions, reconstruction of vocal fold contours after paralysis, laser surgical interventions or injections with botulinum toxin, steroids or cidofovir – we offer those interventions in an ambulatory office-based setting and are proud that we can look back on more than 25 years of experience.
  • Lasers: In Europe we were one of the first clinics offering photoangiolytic KTP laser surgery. With ultrathin glass fibers we are able to obliterate finest blood capillaries painless in a non-contact mode during laryngoscopy – in the awake patient. This procedure is not only applicable in recurrent respiratory papilloma (RRP), but also in many other lesions. Within a few minutes the surgery is done – and in some cases never needs a second treatment. In some patients the operation in general anesthesia can be avoided with this therapeutic strategy.
  • Injection laryngoplasty (augmentation): Injection with a filler substance such as hyaluronic acid (HA), calciumhydroxylapatite (CaHA), collagen, silicone or other biocompatible implants helped hundreds of patients in cases of glottal insufficiency (when the vocal folds do not close). Many patients with unilateral recurrent nerve paralysis achieved great voices after this kind of injection laryngoplasty. Furthermore, patients suffering from vocal fold bowing (synonym presbylarynx) or patients with vocal fold scarring can significantly benefit from augmentation. We perform those augmentations in an ambulatory setting, either in general anesthesia or in an office-based setting.
  • Medialisation thyroplasty: This laryngeal framework surgery enables a permanent medialization of a vocal fold. The implant is placed through an open neck procedure in an in-house setting. Sometimes, we recommend an additional surgery of the arytenoid cartilage, the so called arytenoid adduction.
  • Botulinumtoxin injection: Mostly in patients with spasmodic dysphonia (syn. focal dystonia of the larynx), the laryngeal muscle activity cannot be controlled and needs attenuation by a kind of temporary tonus reduction with botulinumtoxin (BTX). We are able to inject smallest amounts of BTX through a very thin needle into the specific muscles of the larynx – through the neck or indirect transoral or even transnasal. In some cases, we also use laryngeal EMG to guide the tip of the needle into the smaller muscles. Many patients appreciate the short visit and ambulatory injection which sometimes is completed in 15–20 minutes.
  • Transgender: As voice specialists and phonosurgeons we are part of the Transgender Board and competence team of the UKE (University Medical Center Hamburg-Eppendorf). Our part is to offer pitch change operations, mostly male-to-female, in these cases.


Our Voice Center (STIMMZENTRUM) ist an essential part of our voice clinic. The main feature is to offer clients with voice disorders, who are not in need of clinical assistance, non-medical support, guidance, training and coaching. Mostly solist singers, choir singers, actors, teachers and professional voice users benefit from our voice coaching courses and teaching. Individual or group teaching can be helpful to support, develop and refine voice use – either preventive or rehabilitative. Anti-Aging for speaking voice and in singing is another feature that many elderly clients appreciate.
