Voice deepening surgery in Turkey: lowering your pitch for good.

Voice deepening surgery is a laryngeal operation that lowers the fundamental frequency of the speaking voice by reducing the tension of the vocal folds. Its best-known technique is thyroplasty type 3. In the Isshiki classification, this is the type that “relaxes” the vocal folds: vertical incisions are made on both sides of the thyroid cartilage, the cartilage is shortened from front to back and the folds slacken.

The principle is similar to a stringed instrument. A taut string vibrates quickly and gives a high note; a slack string slows down and the sound becomes deeper. Voice deepening surgery does not cut or stitch the vocal folds themselves; it changes the frame they are attached to.

On our voice deepening treatment page we summarised the overall framework of the procedure. Here we focus on a narrower question: is surgery really necessary, and if it is, what can you expect?

Voice deepening surgery is recommended for adults whose voice remains noticeably high for their age and identity and who have not achieved a satisfactory result with non-surgical methods. The decision is not made by ear alone; a laryngoscopic examination and acoustic voice analysis are assessed together.

• Puberphonia: a voice that stays at a childhood pitch even though puberty is complete
• Trans men: those whose voice has not deepened as much as expected despite testosterone therapy
• People who do not or cannot take hormones: those who want to move their voice to a more masculine pitch
• Structurally high-pitched voice: those who cannot hold a pitch lowered through therapy without strain

In voices that become thinner with age (presbyphonia, vocal fold atrophy), the problem is not pitch but the vocal folds not closing fully. In this case, procedures that bring the folds closer together are discussed instead of voice deepening surgery.

In most cases, no. Puberphonia (mutational falsetto) is when a person keeps speaking at a high, childhood pitch even though the larynx has grown during puberty and is structurally adult. The problem lies not in the tissue but in how the voice is used, so the first and main treatment is voice therapy.

In therapy, the person learns to find the deeper voice they already have and to use it in everyday speech. Voice deepening surgery for puberphonia comes into consideration in the following situations:

• If the deeper voice has not become permanent despite regular therapy over a sufficient period
• If the person can produce the deeper voice but cannot sustain it in daily life

In a Brazilian series of type 3 thyroplasties, all 30 patients who had surgery were men with puberphonia. The authors regard the procedure as an option for people who remain unhappy with their voice despite therapy; in other words, pitch-lowering surgery is not an alternative to therapy but the next step after it.

Because testosterone does not work to the same extent for everyone. The hormone increases the mass of the vocal folds and clearly deepens the voice in most trans men; in some, however, the pitch does not fall as far as expected. The voice centre at Weill Cornell Medicine states on its gender-affirming voice care page that pitch begins to fall about 3 months after starting testosterone, with most of the change taking place between months 6 and 9.

This timeline matters, because the pitch may fall a little further on its own while the hormone is still taking effect. That is why surgeons do not plan surgery until the change in the voice has settled. The same centre lists relaxation thyroplasty as an option for transmasculine people who have not reached a satisfactory result with hormones.

• Hormones lower the pitch, but on their own they do not change resonance or speech melody
• Therapy and surgical options are also available to trans men and non-binary people who do not take hormones

There are three ways to deepen the voice: voice therapy, hormone therapy and surgery. They are not competitors but steps that most people try in sequence. The table summarises what each one changes.

Procedures that work in the opposite direction, i.e. surgery that raises the pitch, are explained in our voice feminisation guide in detail.

Voice deepening surgery is performed through a horizontal incision on the front of the neck, at the level of the larynx. In one case published in the medical literature, the procedure was carried out under local anaesthesia and took about an hour and a half, allowing the surgeon to listen to the patient’s voice in real time while shortening the cartilage. The choice of anaesthesia depends on the surgeon and the patient.

1. Remote preliminary assessment. Your voice recordings, medical history, the length of your hormone therapy and any therapy you have had are reviewed.
2. Examination and voice analysis. The vocal folds are viewed by laryngoscopy and the fundamental frequency is measured. The overall course of the trip is described on our treatment process page.
3. Reaching the cartilage. The surgeon goes in through the incision, moves the neck muscles aside and exposes the thyroid cartilage.
4. Relaxation. Vertical cuts are made in the side wings of the cartilage; the cartilage is shortened from front to back, either by overlapping the edges or by removing a thin strip.
5. Fine-tuning the voice. If the patient is awake, they are asked to speak; if the voice sounds rough or breaks up, the position of the cartilage is adjusted again.
6. Fixation and closure. The cartilage is secured in its new position with sutures, and the incision is closed in layers.

Thyroplasty type 3 is a procedure measured in millimetres. In the same case, overlapping the left side impaired the voice, so the surgeon returned that side to its original position; this detail shows clearly why experience is decisive.

Published studies on voice deepening surgery report a meaningful drop, but no one can promise you a specific frequency. In the 30-patient series mentioned above, the average fundamental frequency was about 180 Hz before surgery and measured 109 Hz at six months. In a case report of a trans man who had not responded to hormone therapy, speaking frequency fell from 146 Hz to 110 Hz.

• An average is not your result; if the starting pitch is high, the drop will also look larger
• Frequency is not the only thing that makes a voice sound “masculine”; resonance and speech melody also shape how it is perceived

In the same series, patients’ voice-related complaint scores also fell markedly. Even so, the operation does not create a new voice; it moves your existing voice to a lower pitch.

Recovery is measured less by the incision healing than by the voice settling, and it extends over months. Voice rest is advised for the first few days; the surgeon decides how long, and this varies considerably from centre to centre. The voice becomes clearer as the swelling goes down; in studies, the result is measured at six months.

• Break the habit of clearing your throat; swallow or take a sip of water instead
• Stay away from smoking, and if you have reflux, keep up with its treatment

It would be fair to call it essential. Voice deepening surgery lowers the pitch, but someone who has spoken at a high pitch for years may push their voice back up out of habit. Therapy teaches you to use the new pitch without strain.

The American Speech-Language-Hearing Association (ASHA) explains, in its statement on voice therapy, that therapists work on pitch, intonation, voice quality and resonance, and that trying to change the voice without guidance can lead to fatigue and voice problems. According to Cleveland Clinic’s information on voice therapy, most people have a few sessions a month over several months.

• Before surgery: therapy shows whether surgery is really needed
• After surgery: chest resonance, breath support and speech melody are adapted to the new pitch

The programme usually spans one week to ten days; the surgeon confirms the exact length after the examination. For voice masculinisation surgery, what shapes the trip is not the hospital stay but the check-up at the end of voice rest: before you leave the country, your vocal folds are examined endoscopically and you are given a plan for returning to speaking.

• As you will not be speaking in the first few days, our team handles communication with the airport, hotel and hospital
• Accommodation and transfers are planned around a quiet hotel close to the hospital
• Drink plenty of water on the flight home and keep talking to a minimum
• You send follow-up voice recordings from your phone; they are compared with your baseline recording

Neda Deniz holds the Turkish Ministry of Health International Health Tourism Authorisation Certificate (AK-1032) and acts as an intermediary agency, not a clinic. All procedures, including voice deepening surgery, are performed by our partner specialist surgeons in the relevant hospitals. The doctor we work with in voice surgery is the Ear, Nose and Throat and Head and Neck Surgery specialist Prof. Dr. Kürşat Yelken. Which doctor you proceed with is confirmed after the preliminary assessment. When choosing a surgeon, look at their experience in laryngology and whether voice analysis and therapy are part of the plan.

Turkish regulations do not allow prices for healthcare services to be advertised, and because the scope varies from person to person, a single figure for voice deepening surgery would be misleading. In the UK, waiting lists for NHS gender services can be long and funding for voice surgery depends on individual circumstances, so it is worth checking your own options. When comparing quotes, it is enough to know the items that make up the cost.

• Pre- and post-operative voice analysis: acoustic measurement and endoscopic examination
• Type of anaesthesia and length of the operation
• Hospital and inpatient stay
• Voice therapy: number of sessions and remote option
• Accommodation, transfers and follow-up check-ups

We have gathered answers to general questions on our frequently asked questions page.

The most important risk is that the quality of the voice deteriorates as it deepens. As the vocal folds slacken, their vibration can become irregular. Published studies on pitch-lowering surgery are based on small patient groups, and long-term data are limited.

• Hoarseness and roughness: expected in the first weeks; may be permanent in some people
• Pitch instability: the voice cracking or sliding uncontrollably
• Narrower vocal range: the top notes in particular may be lost; important for singers
• Under- or overcorrection: not reaching the target pitch and needing a second procedure
• Scar on the neck: hidden in a skin crease, but permanent
• Bleeding, infection and anaesthetic risks: as with any surgery

The limits also need to be discussed openly: the operation does not change resonance and does not teach you how to speak. People who rely on their voice for work, such as teachers and singers, should go through each of these points with the surgeon before deciding.

• Hair transplant guide — FUE, DHI and graft planning

Three questions clarify a decision on voice deepening surgery: Have I really tried therapy regularly and for long enough? If I take hormones, has the change in my voice settled? Am I prepared to accept a narrower vocal range and a slightly rougher voice as the pitch comes down? If your answer to any of them is “I’m not sure”, take your time.

A preliminary assessment does not commit you to anything. Send us your voice recording; our partner doctor will review it, and we will explain clearly which voice masculinisation option is right for you. If we think you should continue with therapy first rather than have voice deepening surgery, we will tell you that too.
