Voice Pitch Changes After Hormonal Therapy: Causes and Surgical Solutions
Key takeaways:
Hormonal therapy involving testosterone or similar androgens can thicken and lengthen the vocal cords, lowering voice pitch — and in some cases, this change is permanent.
A deepened voice after hormonal therapy can affect confidence, communication, and professional life, particularly for younger patients.
Surgical options such as Wendler's glottoplasty and laser reduction glottoplasty aim to shorten or reduce the vocal cords to help raise pitch.
Voice therapy alongside surgery plays an important role in helping patients adapt to their new vocal quality.
Hormonal therapy is a common treatment for various gynaecological conditions. While it can be effective in managing symptoms, it sometimes causes unexpected effects on the voice. One such effect is a lowering of voice pitch, which in some cases can be permanent. I recently saw a patient who experienced this exact issue. Her voice had become noticeably deeper, which was affecting her job and confidence. We discussed the range of options available, including surgery to help raise her pitch. In this post, I explain how hormonal therapy can affect voice pitch and the surgical techniques available to patients considering their options.
How Hormonal Therapy Can Affect Voice Pitch
Hormonal therapy often involves hormones such as testosterone or other androgens to treat certain gynaecological conditions. These hormones can influence the vocal cords by thickening and lengthening them, which causes the voice to sound deeper or lower in pitch.
This deepening is more commonly associated with testosterone or similar hormones. For some patients, the change is temporary and reverses after stopping therapy. For others, the effect can be longer-lasting due to structural changes in the vocal cords.
This kind of voice change can be distressing, particularly for younger patients or those whose work depends on their voice. It may affect communication, social interactions, and professional opportunities.
Case Example: A Patient with Lowered Voice Pitch
A patient I recently saw had undergone hormonal therapy for a gynaecological condition. Over time, her voice gradually deepened, and she found it difficult to perform her job, which required a clear, higher-pitched voice. She sought an assessment to explore her options.
During the consultation, we discussed the anatomy of the vocal cords and how hormonal therapy may have contributed to thickening and lengthening of the vocal folds, resulting in a lower pitch. Non-surgical approaches such as voice therapy were discussed, and given the nature of her vocal changes, surgical options were also considered as part of a broader discussion of what might help.
Surgical Options to Raise Voice Pitch
Several surgical techniques exist that aim to raise the pitch of the voice by modifying the vocal cords, generally by shortening or tightening them to increase the frequency of vibration.
Wendler's Glottoplasty
Wendler's glottoplasty is a surgical technique used for pitch raising. It involves shortening the vocal cords by creating a web or fusion at the front portion of the vocal folds, which reduces the vibrating length of the cords.
The procedure is typically performed under general anaesthesia using a laryngoscope. Recovery involves a period of voice rest followed by gradual voice therapy as part of the overall treatment plan.
Laser Reduction Glottoplasty
Laser reduction glottoplasty uses a laser to remove a portion of vocal cord tissue, reducing the mass and length of the cords. The laser allows for precise tissue removal with an aim to minimise impact on surrounding structures.
This technique can be performed under local or general anaesthesia and, like other pitch-raising procedures, is typically paired with post-operative voice therapy.
Cricothyroid Approximation (Largely Superseded)
Cricothyroid approximation was an earlier surgical method that aimed to increase tension on the vocal cords by bringing the cricoid and thyroid cartilages closer together. This technique has largely fallen out of favour due to variable results and complications such as voice monotony, poor long term results, loss of pitch range and strain; and is now rarely performed.
Comparing Surgical Techniques
Each surgical option carries its own considerations. Wendler's glottoplasty is a widely used technique with a well-established recovery pathway. Laser reduction glottoplasty offers precision and a less invasive approach but may involve multiple sessions depending on the individual case.
Cricothyroid approximation is generally not recommended today due to its unpredictable outcomes. The most appropriate option depends on the patient's vocal needs, anatomy, and a detailed discussion with their surgeon.
Voice Therapy and Post-Surgical Care
Surgery is only one part of achieving the best possible voice outcome. Voice therapy plays an important role in helping patients adapt to changes in their vocal cords. A speech therapist can guide patients through exercises addressing pitch control, resonance, and vocal quality.
Post-surgical care also involves a period of voice rest and avoiding vocal strain during healing, along with regular follow-up to monitor progress.
Advanced ENT Care for Complex Voice Issues
Patients facing voice changes due to hormonal therapy or other causes may benefit from a specialised assessment. As an ENT specialist in Singapore with a subspecialty interest in laryngology, I offer detailed voice evaluation to help patients understand their options.
One part of this evaluation is objective voice assessment, such as acoustic phonetogram analysis, which helps characterise vocal function and supports discussion of the most suitable approach — surgical or non-surgical — for each individual.
If you are experiencing voice changes after hormonal therapy, an assessment with an ENT specialist can help clarify the options available to you.
Summary
Hormonal therapy for gynaecological conditions can sometimes lead to a lowering of voice pitch, which in some cases persists over time. This change can affect both personal and professional life. Surgical options such as Wendler's glottoplasty and laser reduction glottoplasty are among the techniques used to help raise pitch by modifying the vocal cords.
The right approach depends on individual anatomy and vocal needs, and is best determined through a detailed consultation. Voice therapy alongside surgery is an important part of the overall treatment pathway.
If you are affected by voice changes after hormonal therapy, an ENT consultation can help you understand your options.
