Tracheal shave & voice-preserving chondrolaryngoplasty.

Eliminating one of the most unmistakable secondary masculine markers—the prominent Adam's apple. Through a concealed submental micro-incision or transoral endoscopic access, our surgeons sculpt the thyroid cartilage notch into a smooth, graceful feminine neck silhouette while guaranteeing 100% vocal cord preservation via direct fiberoptic laryngoscopy.

Laryngeal microsurgery

Anatomical pillars of safe Adam's apple reduction

During male puberty, testosterone fuses the two thyroid cartilage laminae at an acute 90° angle (compared to 120° in biological females), projecting the laryngeal prominence forward. Our protocol flattens this projection with microscopic precision.

01Vocal preservation

Direct fiberoptic vocal cord mapping

The anterior commissure of the vocal cords (Broyles' ligament) attaches directly to the inner surface of the thyroid cartilage just below the prominent superior notch. Blindly shaving too far downward can destabilize the vocal cords and permanently lower or hoarsen the voice. We utilize real-time transnasal/laryngeal fiberoptic endoscopy and needle transillumination to mark the exact millimeter boundary of the vocal cord attachment before removing a single millimeter of cartilage.

Real-time endoscopic visualization of the anterior vocal commissure
Strict 2 to 3 mm structural safety margin preserved above Broyles' ligament
Zero risk of vocal fold detachment, pitch drop, or chronic hoarseness
Full protection of the superior and recurrent laryngeal nerves

02Scar camouflage

Remote submental crease micro-incision

An incision placed directly over the Adam's apple is a telltale sign of surgery and frequently adheres to underlying tissue, moving up and down when swallowing. Instead, our surgeons place a tiny 1.5 to 2 cm micro-incision high up in the natural shadow crease directly beneath the chin (cervicomental angle) or offer a 100% scarless transoral vestibular approach inside the lower lip.

Multi-layer perichondrial and platysmal closure preventing skin tethering
Subcuticular absorbable sutures with post-op medical silicone therapy

03Smooth neck contour

Ultrasonic & micro-burr cartilage beveling

In younger patients, the thyroid prominence consists of pliable hyaline cartilage shaved with fine micro-blades; in patients over 25–30, the cartilage progressively calcifies into hard bone. We employ diamond micro-burrs and ultrasonic piezoelectric instruments to smoothly resect the V-shaped superior thyroid notch and bevel the lateral thyroid alae, creating a soft, continuous feminine throat contour.

3D lateral beveling eliminating sharp edges or palpable ridges under thin neck skin
Inner and outer perichondrium preservation to promote smooth healing

Clinical scope

Standalone chondrolaryngoplasty vs. combined voice & FFS synergy

Whether performed as a quick standalone refinement or integrated into a full facial and vocal feminization session, our laryngeal protocol adapts to your transitional goals.

Seamless surgical synergy

Combined FFS, V-line & glottoplasty integration

The most popular and efficient pathway: pairing tracheal shave with lower-face V-line contouring, deep-plane neck lifting, or endoscopic voice feminization surgery (VFS) under a single anesthesia session.

Shared cervicomental aesthetics: Combining Adam's apple reduction with V-line jaw/chin contouring or submental liposuction sculpts an unbroken, swan-like jawline and neck transition.
Simultaneous voice pitch elevation: While tracheal shave alone only changes external appearance, it can be safely paired with endoscopic Wendler glottoplasty or LAVA to raise vocal pitch into the feminine frequency range (180–220+ Hz).
Single anesthesia & recovery: Adds less than 45–60 minutes to a comprehensive FFS session with zero additional downtime.
Scarless transoral option: When performed alongside intraoral V-line jaw surgery, the Adam's apple can be accessed through the same lower-lip mucosal incision.

Focused rapid protocol

Standalone micro-incision tracheal shave

Ideal for patients who already possess naturally soft facial features—or have completed facial surgery—and wish to eliminate a visible Adam's apple with minimal recovery time.

Rapid 60-minute execution: Performed under general anesthesia (with LMA airway for endoscopic visualization) as a day-surgery or 1-night inpatient stay.
High submental crease placement: Hidden in the natural fold beneath the chin so the healing line is invisible in normal conversational posture.
Immediate vocal capability: Unlike voice surgery, standalone tracheal shave requires no prolonged voice rest—you can speak normally the same day.
Fast return to travel: Minimal swelling and bruising allow international patients to enjoy Bangkok and fly home within 5 to 7 days.

Clinical pathway

The tracheal shave transformation timeline

From pre-operative laryngeal ultrasound/CT and fiberoptic mapping to rapid recovery in our Bangkok sanctuary.

Phase 1

Laryngeal assessment, calcification check & crease marking

Physical palpation and high-resolution imaging evaluate the prominence of your thyroid notch, degree of age-related cartilage ossification, and vocal fold anatomy. With you seated upright, the surgeon marks the submental crease beneath your chin to ensure optimal scar concealment.

Duration: Pre-op consultation & day 1 in Bangkok

Phase 2

Endoscope-guided cartilage sculpting & hospital stay

A 60 to 90-minute microsurgical procedure in our JCI-accredited hospital tower. Using a Laryngeal Mask Airway (LMA) and fiberoptic endoscope, the surgeon visualizes your vocal cords from the inside while sculpting the prominent outer thyroid cartilage flush. The strap muscles and perichondrium are meticulously re-approximated, and a fine subcuticular closure is sealed with sterile surgical strips.

Duration: Outpatient or 1 night inpatient

Phase 3

Sanctuary recovery, comfortable swallowing & check-up

Relax in your private luxury recovery hotel suite. Mild throat soreness (similar to a light cold) and gentle swelling resolve within 3 to 5 days with cooling compresses and lozenges. You can speak and eat soft foods immediately. Our nursing team checks your incision daily until your day 5–7 surgeon clearance to fly home.

Duration: 5 to 7 days in Bangkok

Phase 4

Edema resolution & invisible scar maturation

The flattened neck profile is visible immediately after surgery, with residual micro-swelling over the cartilage settling completely over 4 to 8 weeks. Applying our medical-grade silicone gel and UV protection ensures the tiny submental crease line fades into an imperceptible hairline trace over 3 to 6 months.

Duration: Month 1 to 6+

Patient inquiries

Frequently asked questions

Authoritative medical answers regarding voice pitch, vocal cord safety, cartilage regrowth, scar placement, and combining tracheal shave with voice surgery.

Does a tracheal shave change my voice or make it higher?

No. A tracheal shave (chondrolaryngoplasty) is strictly an external contouring procedure that removes the prominent upper V-notch of the thyroid cartilage; it does not alter the length, tension, or vibrating mass of your vocal cords inside the larynx. Therefore, your voice will not become higher from a tracheal shave alone—and thanks to our intraoperative fiberoptic laryngoscopy protocol, your natural vocal strength and pitch are 100% protected from accidental damage. If you wish to surgically raise your vocal pitch into a feminine range, we can perform endoscopic voice feminization surgery (Wendler glottoplasty) during the same session.

How do you ensure the surgeon removes the maximum amount of cartilage without harming the vocal cords?

Surgeons who operate "blindly" from the outside either leave too much Adam's apple behind out of fear, or shave too low and detach the anterior commissure tendon (Broyles' ligament), which permanently ruins vocal pitch. At Sissy Clinic, our anesthesiologist uses a Laryngeal Mask Airway (LMA) rather than a bulky endotracheal tube, allowing our surgeon to pass a high-definition fiberoptic camera down to view your vocal cords directly on a monitor during surgery. A fine sterile needle is passed through the cartilage above the cords to pinpoint the exact internal attachment level, enabling aggressive, completely flat cartilage removal above that line with zero risk to your voice.

Can the Adam's apple grow back after a tracheal shave?

No. Once the prominent thyroid cartilage and any calcified bone are surgically resected, adult laryngeal cartilage does not regenerate—making the result 100% permanent for life. In the first 3 to 6 weeks after surgery, normal localized post-operative swelling and scar tissue maturation over the smoothed perichondrium can temporarily feel slightly firm to the touch, which some patients mistake for residual cartilage. As this mild edema resolves over 2 to 3 months, the neck contour becomes completely flat, soft, and smooth.

Why is the incision placed under the chin rather than directly over the Adam's apple?

In cisgender women, the vertical front of the neck is completely smooth and unblemished; a horizontal scar sitting right in the middle of the throat over the larynx can draw unwanted attention and act as a visible surgical tell. Furthermore, incisions directly over the shaved cartilage can heal tethered to the trachea, causing the skin to dimple and pull upward every time you swallow. By placing a tiny 1.5 cm micro-incision high up in the submental shadow crease under the chin (or inside the mouth), the vertical neck remains 100% scar-free and skin tethering is prevented.

What does recovery feel like, and when can I eat, speak, and travel?

Tracheal shave is one of the most comfortable and rapid recoveries in gender-affirming surgery. Patients typically experience a mild sore throat when swallowing—comparable to a minor cold—for 2 to 4 days, along with slight tightness under the chin. You can speak normally right after waking up and resume normal meals within 24 to 48 hours. When performed as a standalone procedure, patients are cleared for international flights within 5 to 7 days.
