Voice Feminization Surgery (VFS)

Surgical voice adaptation man-to-woman transgender

Sounds really feminine!

If a person’s voice doesn’t match their gender, you don’t have to put up with it; you can do something about it. If you feel you belong to the female gender, you also want to be perceived as such and addressed accordingly, e.g. on the telephone. Every time! If the voice does not match the identity, this often leads to frustration, silence or social isolation. We want to help women develop a voice and appropriate communication that reflects your true gender. Voice feminization is an important step in the overall passing.


„My voice is my second face“

„For me, a female voice means no longer being tense. Being able to let go! I was always just tense. Physically as well as mentally. The voice is the residue of tension that I still feel from my previous life. And I want to get rid of that tension too.“
K.J. April 2021

At the MEDICAL VOICE CENTER we offer a team approach. Our SLPs offer training in resonance, speaking patterns, efficient voicing and pitch while our laryngologist offer pitch elevation surgery through modified Wendler Glottoplasty. Throughout the process we work closely with the patient so that we can meet their unique goals and that they can make informed decisions.
The goal is a voice that, in the overall context of speaking, has all the feminine characteristics that make up a woman’s voice. Voice-enhancing surgery alone leads to a completely satisfactory result in very few cases.
The MEDICAL VOICE CENTER is a renowned voice center specializing in voice feminization surgery.
For each individual patient we take a lot of time, listen carefully and do not let go until we understand all your concerns and sensitivities.

A very experienced surgeon

Markus M. Hess, MD, PhD, routinely performs voice raising surgeries, a total of about 50-80 glottoplasties per year. He lectures worldwide and is  leading the field of research into surgical methods and Trans*Voice-Therapy. The voice therapy developed by Prof. Hess in collaboration with leading SLPs is precisely tailored to the needs of trans patients.

Voice feminization surgeries focus on raising the pitch and reducing the ability to produce a low-pitched voice. The goal is a voice that has all qualities of a female voice. To get this it is necessary to train the new voice after the surgerty by a professional voice-therapist. The integration of speech therapy and surgery is essential to improve the outcome of the treatment.
The MEDICAL VOICE CENTER developed a special pre-operative voice feminization therapy for women who want to have an authentic female voice and match their gender identity. This trans*voice-therapy is part of our feminization package.

The first two surgical methods listed on the right  are performed in microlaryngoscopy. The CTA and FemLar require an intervention on the outer neck. (Note: The reduction of the Adam’s apple, the so-called chondroplasty or trachel shave, does not lead to a change of voice. The most common surgical techniques for voice feminization are described here  (in German language)

  • Glottoplasty (according to Wendler, Gross, Kim, Anderson and others)
  • Laser Reduction Glottoplasty (according to Orloff)
  • Cricothyroidale Approximation (CTA according to Isshiki et.al.)
  • Feminization Laryngoplasty (FemLar according to Thomas)

Preparing your voice feminization surgery

The voice change operation starts with a detailed interdisciplinary initial discussion together with the surgeon Prof. Dr. med. Markus M. Hess as well as the speech therapist (voice and speech trainer). This interview will also analyze the potential need for preoperative vocal therapy. Our treatment package ‚voice-feminization’ comprises interdisciplinary history taking with a physician (ENT doctor) trained in voice disorders / phonosurgery and a logopedist specially trained in clinical voice disorders / vocal coaching. Diagnostics include videostroboscopy, endoscopy, electroglottography, electroacoustic voice analyses, perceptual voice assessment, voicerange profile, Acoustic Voice Quality Index, Transsexual Voice Questionnaire and further tests. Subsequently a detailed briefing and discussion are offered. In case of surgery, a consent form is handed out explaining in detail all options for the following feminization laryngoplasty procedure.
Prof. Markus Hess provides you with information about treatment options and alternatives (conservative and surgical) and explains you all possible surgical procedures.

Glottoplasty costs

The expertise of the surgeon makes a big difference
Microsurgical voice feminization is a routine procedure for very few surgeons. Personal knowledge, operative experience with exactly these issues of glottoplasty, technical microsurgical adeptness as well as the constant operation routine and frequency are the decisive factors for the success of the operation.
Absolute specialists are often more expensive than generalists who perform the procedure only occasionally to expand their portfolio. When choosing a surgeon, be guided by the surgeon’s specialist expertise and success rate – not by prices. Especially with glottoplasty, there is never as good a chance of success as with the initial procedure. You should choose wisely who you trust with your voice.

The voice feminization surgery

The voice feminization surgery (glottoplasty) is based on three keystones:
1. Shortening of the vocal cords.
2. Change the vibration dynamics of the vocal cords.
3. Reduction of the vibratory mass of the vocal cords.

Outpatient glottoplasty is painless and under general anaesthesia. The only a few millimeters short vocal cords are permanently connected with two hair-thin, firm threads.
This surgery creates a web or scar band at the front of the V of the vocal cords. This shortens the vocal cords to help raise voice pitch. Anterior glottal web formation affects frequency range by eliminating the ability to produce lower pitches.

An additional injection of the vocal folds with a temporary implant reduces the tensile forces on the sutures during the postoperative period. Depending on the vocal fold volume, ablation is performed using the LAVA method. In addition, if necessary, the vocal folds are temporarily sedated with BTX.

Voice feminization surgery and aftercare

Surgery is carried out ambulatory by Prof. Hess. The surgery will take place in the Ambulatory Operations Center (AOZ) about 200 meters further away. There we work together with very experienced and highly qualified medical staff. After the surgery in general anesthesia, the postoperative monitoring follows in the recovery room. About 2 hours later, we conduct the follow-up examination in the MEDICAL VOICE CENTER with postoperative video laryngoscopy and detailed after-care consultation and discussion of the following steps. As a general requirement in Germany, all patients receiving general anesthesia need an accompanying person for a 24 hour period.
The next day you come to the check-up and the further scheduling will be planned. We discuss the follow-up examinations in the following months.
Your therapeutic care includes pre- and / or postoperative speech training according to your personal needs. We offer you up to 10 sessions, individually planable  and / or in connection with the medical follow-up. Postoperatively, after the „release“ of the voice by Prof. Hess, the first voice training takes place.  Therapy via Skype is always possible.

Medical follow-up

We individually discuss the follow-up examinations in the following months. Normally, we ask our patients after 2 and 6 weeks and after 6 and 12 months for laryngeal examinations, acoustic analysis and for new voice recording.

You therapeutical care includes pre-and / or postoperative speech training or speech therapy according to personal needs. We offer you up to 10 sessions, individually planable also in double lessons, in blocks and / or in connection with the medical follow-up. Postoperatively, according to our rehabilitation scheme, it will soon be possible to whisper ‚loose‘ again. After the „release“ of the voice by Prof. Hess is started after 3-5 weeks with first vocal exercises.

Please feel free to call us. A telephone consultation is of course free of charge.

Targets of Trans*Voice Therapie

  • Prosody is the melody of speech and includes loudness, pitch and stress changes. Men tend to use stress or loudness for emphasis, while women often use greater pitch variability.

  • Vocal resonance. This term often refers to the perception of vibrations when using one’s voice. The location of vocal resonance isn’t fully dependent on your gender. You can have a throaty resonance, where vibrations are focused in the throat or chest, or a forward resonance, where vibrations are experienced around the lips and nose. A speech-language pathologist can help you find a healthy resonance that reflects who you are. This takes practice, exploration and experimentation with your voice.

Therapy will also address:

  • Voice quality

  • Articulation

  • Speech rate and phrasing

  • Nonverbal communication, such as eye contact, use of hand gestures, facial expression, posture and head nodding

The voice feminization package contains:

• Pre-operative vocal exercises • Post-operative vocal rehabilitation • Sociocultural feminization • Surgery, glottoplasty and medical follow-up • Speech therapy (articulation, speech melody and speech) • Resilience training of the new voice • Reinforcement of female pitch and resonance • Coaching and conversations to authentic female communication patterns. Your therapeutic care includes pre- and post-operative speech training or speech therapy according to personal needs. We offer you up to 10 sessions, individually planable in double lessons, in blocks and / or in connection with the medical follow-up. Postoperatively, according to our rehabilitation scheme, it will soon be possible to whisper ‚loose‘ again.

Our flat rate offer includes a whole spectrum of medical and nonmedical services, where multidisciplinary pre- and postoperative voice care and consultation are obligatory and are always accepted with great appreciation.

3-5 weeks after the „release“ of the voice by Prof. Hess, we start with first vocal exercises.
