The basic element that constitutes the perception of thinness and thickness of our sound is the number of vibrations that our sound wires generate during sound production, that is the fundamental frequency of our sound. The basic frequency of sound in a healthy man is expected to be below 120 Hz and in a healthy woman above 150 Hz. Briefly, the higher the basic frequency of the sound, the thinner the sound, the thicker the lower the frequency.

The factors that determine the basic frequency of our voice are the length, thickness and tension of our vocal cords. It is necessary to lengthen, thin, and increase the tension of the vocal cords to thin the sound, while to shorten the vocal cords, thicken and reduce the tension. Therefore, the changes to be made on these 3 parameters lead to changes in sound thinness and thickness.

The need to dilute the sound may be caused by different reasons. The desire for gender change is one of the leading reasons. A new voice in line with the changing physical appearance is undoubtedly the most indispensable element of the desired new sexual identity.

For women who have had hormone treatment in their childhood or have some hormonal problems, it is undoubtedly socially distressing. Sound thickening is also a common problem in middle-aged women with a history of intensive smoking. Or simply, there are no pathological conditions, and some women may have a thicker voice.

The common goal for all these groups is to refine the sound. Nowadays, it is possible to dilute the sound with some surgical procedures. These surgical interventions, which are applied through a small incision made both in the mouth and neck, are effective and provide a thinning that may meet the expectations.


Several different surgical techniques may be applied to thin the sound. The most well-known of these is the Type 4 thyroplasty procedure, which has been used for this purpose for approximately 40 years. In this surgical technique performed under local anesthesia, it is aimed to extend the vocal cords by extending a small incision from the anterior lower part of the neck and extending the vocal cords and thus thinning the sound. It is also possible to simultaneously shave the Adam diamond projecting in the anterior aspect of the neck, especially for patients who require sex change.

Surgical interventions performed in the mouth for thinning of the voice naturally have an important advantage of not leaving any incision marks on the skin. These techniques are also easily tolerated by patients because they are performed under general anesthesia. For this purpose, the two techniques that have become more popular nowadays and are frequently applied are Wendler thyroplasty and Laser thinning (LAVA).

In Wendler thyroplasty, the anterior1/3 part of the vocal cords is sutured to each other to shorten the vocal cords and to increase the tension of the vocal cords. It is a very successful technique and is one of the most preferred surgical procedures for this purpose. In LAVA, it is aimed to decrease the mass of the sound wire with the help of laser and to reduce the sound.

Utilizing sound therapy during the healing process of all these surgical procedures is extremely beneficial in terms of sound settling and permanent.

The sound is rested for one week after surgery.
