Background
Defining Feminization Laryngoplasty
Feminization laryngoplasty (FL), also known as FemLar or Femlar, is a reconstructive surgical procedure aimed at increasing a patient's vocal pitch, resulting in a higher, more feminine voice quality. It is a form of open laryngoplasty that involves a partial laryngectomy of the anterior larynx. This reduction in size effectively modifies the larynx to proportions typically associated with cisgender females, thereby altering the vocal weight and resonance characteristics of the voice.
Purpose and Application
This surgical intervention is primarily sought by transgender women and non-binary individuals as part of their gender transition process. It also serves cisgender women who experience dysphoria due to having a naturally deep voice. The procedure is considered an alternative to voice therapy when non-surgical methods do not yield satisfactory results.
Efficacy and Comparison
Studies indicate a high long-term satisfaction rate regarding the pitch changes achieved through feminization laryngoplasty. The measured pitch increase is generally greater than that achieved with Wendler Glottoplasty, another procedure that shortens the vocal cords endoscopically. On average, patients experience an upward shift of approximately 6 semitones (20-80 Hz) in their comfortable speaking pitch. While rare, instances of excessive pitch increase have been documented, suggesting the importance of precise surgical calibration.
Transgender Voice Considerations
Hormonal Impact on Larynx
During puberty, testosterone, the primary male sex hormone, causes significant irreversible changes in the larynx. These include an increase in diameter and thickening/lengthening of the vocal folds. Even with feminizing hormone therapy, these changes do not reverse. Consequently, the fundamental and resonant frequencies of the voice decrease, often resulting in a pitch that does not align with a transgender woman's gender identity.
Aesthetic Benefits
Beyond vocal pitch modification, feminization laryngoplasty can also address the physical appearance of the neck. The removal of anterior cartilage, particularly the thyroid cartilage, reduces the prominence of the "Adam's apple." This contributes to a more typically feminine neck profile, an effect that is more pronounced than that achieved by a standard tracheal shave, which surgeons typically avoid altering significantly to preserve vocal function.
Non-Binary and Cisgender Applications
Tailored Vocal Goals
While transgender women are the primary candidates, cisgender women with naturally low voices and gender non-conforming individuals may also pursue this surgery. It is important to note that the desired vocal outcome can vary. Non-binary individuals, for example, might aim for an androgynous voice rather than a strictly feminine one. Close collaboration between laryngologists and patients is essential to customize the procedure and maximize satisfaction.
Voice Therapy as a Precursor
Non-Surgical Voice Modification
Voice therapy is typically recommended as a first step for individuals seeking vocal alteration. Through targeted exercises, patients can learn to modify their habitual pitch, resonance, and intonation to achieve a more feminine vocal quality. This approach requires consistent practice and conscious effort to maintain the desired voice characteristics.
Limitations of Therapy
While effective for many, voice therapy alone may not achieve the desired results for everyone. Prolonged or aggressive use of a modified voice can sometimes lead to vocal strain or pathological issues. In such cases, or when therapy results are unsatisfactory, surgical options like feminization laryngoplasty offer a permanent solution for adjusting speaking pitch and resonance.
Surgical vs. Non-Surgical Prevalence
Data suggests that a smaller percentage of transgender women opt for surgical voice feminization compared to non-surgical methods. While approximately 1% may choose surgery, a larger proportion (around 14%) engage in voice therapy. However, surgery provides a definitive and lasting change.
Historical Context
Evolution of Gender Affirmation Surgery
The broader field of transgender surgery gained significant public attention following the experiences of Christine Jorgensen in the early 1950s. Initially focused primarily on genital reconstruction, gender affirmation surgery has evolved considerably. In recent decades, there has been a growing emphasis on addressing secondary sex characteristics, leading to increased focus on procedures like voice feminization.
Rise of Voice Feminization
The increasing societal understanding and acceptance of diverse gender identities have spurred advancements in procedures aimed at aligning physical characteristics with gender identity. Studies suggest that for many patients, achieving social recognition through modifications of secondary sex characteristics, including voice, is highly satisfying, sometimes even reducing the desire for further genital surgery.
Traditional Techniques
Early Pitch Elevation Methods
The earliest experimental surgical attempts to raise vocal pitch date back to 1979 with Kazutomo Kitajima and colleagues. They established a relationship between the distance between the thyroid and cricoid cartilages and vocal pitch. This led to the development of Cricothyroid Approximation (CTA), a procedure designed to increase pitch by reducing this separation. Despite its historical significance, CTA often results in an unnatural falsetto quality.
Alternative Surgical Approaches
Other surgical techniques emerged to address the limitations of CTA. These include Wendler Glottoplasty (also known as anterior web glottal formation or VFSRAC - Vocal Fold Shortening with Retrodisplacement of the Anterior Commissure) and its variants like laser reduction glottoplasty (LRG). Laser tuning methods, such as laser-assisted voice adjustment (LAVA) and vocal fold muscle reduction (VFMR), were also developed. While these methods avoid the falsetto issue, they often involve more complex recovery periods.
Modern Technique: Feminization Laryngoplasty
Origins and Advantages
Feminization laryngoplasty evolved from the open laryngoplasty technique proposed by surgeon Somyos Kunachak. James P. Thomas performed the first documented feminization laryngoplasty in 2003. This modern approach offers a more significant and lasting pitch increase compared to earlier methods, while also producing a more naturally feminine voice quality. Crucially, it preserves the function of the cricothyroid muscle, allowing for flexibility in vocal range, including the falsetto register.
Integrated Approach
A key advantage of feminization laryngoplasty is its ability to combine voice feminization with aesthetic neck contouring. It incorporates thyroid chondroplasty to reduce the prominence of the Adam's apple within a single procedure. This contrasts with other techniques that may require separate surgeries for these goals.
Anesthesia Considerations
Initially, some feminization laryngoplasty procedures were performed under local anesthesia. However, general anesthesia is now generally preferred. This approach helps prevent patients from inadvertently speaking during the procedure, which could compromise suture integrity and lead to complications.
The Surgical Procedure
Presurgical Management
Prior to surgery, patients typically receive intravenous antibiotics, such as clindamycin and ceftriaxone, to minimize the risk of infection. Dexamethasone may also be administered to reduce post-operative edema. Baseline voice recordings are essential for comparative analysis of pitch and quality changes following the procedure.
Incision and Vocal Fold Modification
Under general anesthesia, a horizontal incision, approximately 5 cm in length, is made along a skin crease above the thyroid notch to ensure scar concealment. Superficial flaps are created, and the strap muscles are separated midline to expose the thyroid cartilage. A portion of the anterior thyroid cartilage is then removed using electrocautery. This step reduces the prominence of the Adam's apple and decreases the overall diameter of the laryngeal opening.
Furthermore, approximately one-quarter of the anterior false vocal folds may be resected to further narrow the upper larynx and improve visualization of the true vocal folds. Subsequently, up to 50% of the anterior true vocal folds can be removed, and the pharyngeal length shortened, to elevate the speaking pitch. This reduction in the glottal region's size also diminishes the thyroid notch.
Visual Representation Note: Medical illustrations often depict a cross-section of the thyroid cartilage. These typically show the cartilage being cut horizontally, with a central segment removed, and the remaining superior and inferior portions being sutured together to achieve the desired reduction in size and prominence.
Thyrohyoid Elevation
The thyrohyoid muscle is elevated to decrease the distance between the thyroid cartilage and the hyoid bone. This elevation may be enhanced by removing portions of the upper thyroid alae to provide more space. Finally, the larynx is suspended higher in the neck by drilling holes in the thyroid cartilage and hyoid bone for sutures and screws, while still allowing natural movement for functions like swallowing. The strap muscles are reattached, and the skin incision is closed.
Postoperative Care
Following surgery, patients are typically discharged the same day unless complications arise. Pain management involves acetaminophen, potentially with narcotic analgesics. Antibiotics like cefpodoxime or levofloxacin are prescribed for approximately seven days to prevent infection. Strict voice rest is mandated for at least two weeks to allow for proper healing and scar tissue development. Patients are advised to avoid strenuous activity for three weeks and weightlifting for one month. Intubation for other medical procedures should be avoided for at least three months post-surgery.
Risks and Complications
Voice Quality Changes
Post-surgery, patients may experience a reduction in vocal volume and, in some cases, an undesirable drop in pitch or disruption of vocal range continuity. This can make the procedure less suitable for professional voice users such as singers. For these individuals, alternative procedures like Vocal Fold Shortening and Retrodisplacement of the Anterior Commissure (VFSRAC) or laser tuning techniques might be considered.
Granuloma Formation
A potential complication is the development of granulomas on the vocal cords, which can manifest as a breathy or whispery voice. These may resolve spontaneously or require manual removal.
Visual Note: Images of vocal cord granulomas typically show inflamed tissue formations, often at the posterior part of the vocal folds, which can impede normal vibration.
Dysphonia and Hoarseness
Temporary dysphonia (hoarseness) is common in the initial recovery period (up to two months). While this usually resolves, persistent or severe hoarseness may necessitate further treatment or revision surgery. Asymmetrical healing of the vocal cords can also occur, potentially requiring laser correction.
Airway Obstruction
In rare instances, severe post-operative swelling can compromise the airway, leading to breathing difficulties. Such cases may require a tracheostomy to establish an alternative airway.
