Surgery is the only reliable way to permanently enlarge the Adam’s apple. The laryngeal prominence, that visible bump on the front of the throat, is shaped by the thyroid cartilage, and its size is largely set during puberty by testosterone exposure. For people seeking a more prominent Adam’s apple, two surgical techniques have documented results: synthetic implants placed over the thyroid cartilage, and grafts carved from the patient’s own rib cartilage. Non-surgical approaches exist, but their effects range from modest to nonexistent.
What Determines Adam’s Apple Size
The Adam’s apple forms where the two plates of the thyroid cartilage meet at the front of the throat. During puberty, testosterone drives the larynx to grow, and in males this growth is more dramatic. The cartilage plates fuse at a sharper angle, pushing outward to create a more prominent bump. A 2024 CT imaging study quantified these differences: the angle at the thyroid notch averaged about 65 degrees in males compared to roughly 89 degrees in females, and the cartilage depth was about 10 mm in males versus about 8 mm in females.1Journal of the Medical Association of Thailand. Gender Differences in Thyroid Notch on Computed Tomography in Thailand A sharper angle means a more pointed, visible bump; a wider angle means a flatter, less noticeable contour.
The cartilage itself also behaves differently between sexes. Female thyroid cartilages retain more of certain sugar-protein molecules that resist mineralization, keeping the cartilage softer and more flexible throughout life. Male cartilages mineralize earlier and more extensively, contributing to their rigidity and visibility.2PubMed Central.

Once you’re past that developmental window, the cartilage doesn’t keep growing on its own.
Surgical Augmentation with Implants
The most straightforward surgical approach uses a synthetic implant placed directly over the thyroid cartilage. In a documented case, a porous polyethylene nasal shell implant was adapted for this purpose. The surgeon made an incision in a natural neck crease, separated the strap muscles running vertically along the front of the throat, and placed the trimmed implant in a submuscular pocket over the thyroid cartilage. A V-shaped notch was carved into the top edge to replicate the natural contour of a prominent thyroid notch, and a small wafer graft was tucked underneath for additional definition.3Explore Plastic Surgery.

Porous polyethylene was chosen because tissue grows into its surface over time, anchoring the implant in place. The material conforms well to the curved anatomy of the larynx, and placing the implant beneath the strap muscles rather than directly under the skin gives it a natural appearance and stable position.4Explore Plastic Surgery. Adam’s Apple Augmentation for Neck Masculinization Case Study – Section: Discussion Because the implant sits on the outer surface of the cartilage, it doesn’t interfere with the vocal cords or the larynx’s internal structure. The result is a visible bump that moves up and down during swallowing, just like a naturally prominent Adam’s apple.
One real advantage of this method is adjustability during surgery. The implant can be trimmed, re-shaped, and tried in place before the incision is closed, giving the surgeon fine control over how much prominence to add. If the initial sizer looks too wide or too narrow, modifications take only minutes.
Rib Cartilage Grafting
For people who want to avoid synthetic materials entirely, an alternative technique uses the patient’s own rib cartilage. In what was described as the first procedure of its kind for female-to-male facial confirmation, surgeons harvested a section of rib cartilage, carved it to match the thyroid cartilage’s natural shape, and attached it as an onlay graft directly onto the existing cartilage framework.5PubMed. First Female-to-Male Facial Confirmation Surgery with Description of a New Procedure for Masculinization of the Thyroid Cartilage (Adam’s Apple)
The key advantage is biocompatibility. There’s no foreign material in the body, so implant rejection isn’t a concern. The grafted rib cartilage integrates with the native thyroid cartilage over time, creating a fully mobile structure that moves naturally with swallowing.5PubMed. First Female-to-Male Facial Confirmation Surgery with Description of a New Procedure for Masculinization of the Thyroid Cartilage (Adam’s Apple) The trade-off is that rib harvesting adds a second surgical site, usually on the chest, which means an additional scar and somewhat longer recovery. There is also a small possibility that living cartilage grafts resorb slightly over the years, meaning the final result might shift a bit as the body breaks down and remodels some of the transplanted tissue.
Implant Versus Graft in Practice
If you’ve decided surgery is the route, the choice between these two techniques comes down to a few practical trade-offs rather than a clear winner.
- Shaping flexibility: Implants can be sized up or down during the operation, which makes intraoperative adjustments easier. Rib cartilage can also be carved to specification, but the material is less forgiving of repeated trimming.
- Second incision: Rib grafting requires a chest donor site. Implants need only the single neck incision.
- Foreign body risk: Any synthetic implant carries a small baseline risk of infection or, very rarely, extrusion. Autologous cartilage avoids this entirely.
- Long-term stability: Porous polyethylene anchors through tissue ingrowth and tends to maintain its shape indefinitely. Rib cartilage integrates biologically but may undergo partial resorption over years.
Both approaches require a surgeon experienced specifically in thyroid cartilage augmentation. This procedure is far rarer than its reverse counterpart (tracheal shave), so the pool of surgeons with meaningful case volume is small. Asking to see before-and-after photos of prior augmentation cases, rather than relying on general facial surgery credentials, is the most useful vetting step.
Can Testosterone Therapy Enlarge the Adam’s Apple?
For transgender men and others starting testosterone, one of the most common hopes is that hormone treatment will produce a visible Adam’s apple. Testosterone does cause the vocal cords to thicken and the larynx to grow slightly, which is why voice deepening is among the more predictable effects of masculinizing hormones. But external cartilage prominence depends on the angle and dimensions of the thyroid cartilage plates, and those were largely established during the patient’s first puberty.
The thyroid notch angle in males averages about 65 degrees, compared to roughly 89 degrees in females.1Journal of the Medical Association of Thailand. Gender Differences in Thyroid Notch on Computed Tomography in Thailand A second, testosterone-driven puberty in adulthood can narrow that angle somewhat and add some cartilage growth, but the plates typically don’t re-angle themselves to the same degree they would have during adolescent development. This is why some trans men on testosterone develop a noticeable Adam’s apple while many others don’t. The outcome depends partly on original cartilage geometry and partly on individual variation in how the cartilage responds to androgens later in life. For people who want more prominence than testosterone alone provides, surgical augmentation remains the most dependable option.
Why Non-Surgical Approaches Fall Short
Advice circulating online suggests that neck exercises, posture adjustments, or injectable fillers can create a bigger Adam’s apple. The reality is more sobering.
Neck exercises and body composition changes don’t alter the thyroid cartilage itself. What they can do is change how much of it shows through the skin. A leaner neck with less subcutaneous fat reveals more of whatever cartilage prominence already exists. So losing body fat can make an existing Adam’s apple more visible, sometimes surprisingly so. But if the underlying cartilage angle is wide and the prominence is flat, no amount of leanness will create a bump that isn’t structurally there.
Voice training programs that teach people to carry the larynx in a lower position during speech do successfully lower habitual speaking pitch. Research on behavioral pitch-lowering treatment has shown measurable reductions in speaking fundamental frequency and the effort required to speak in a lower range.6Journal of Voice. Behavioral Treatment Approaches to Lowering Pitch in the Female Voice But altering habitual larynx position during speech doesn’t change the cartilage’s structure or its resting prominence when you’re not speaking. Voice training is valuable for its intended purpose; it just isn’t a path to a visually bigger Adam’s apple.
Dermal fillers placed over the thyroid cartilage have been discussed in online communities but are not an established medical procedure for this area. The anterior neck is highly mobile, and the constant motion from swallowing, head turning, and neck flexion makes filler placement inherently unstable compared to, say, the cheekbones. Fillers also resorb within months, requiring repeated sessions. And the neck’s anatomy, with the airway and major blood vessels close to the surface, raises the risk profile beyond what a typical facial injection entails. No peer-reviewed literature documents dermal filler augmentation of the Adam’s apple as a standard technique.
Recovery After Augmentation Surgery
Recovery from Adam’s apple augmentation is generally straightforward. For implant procedures, the incision typically hides in a natural neck crease. Swelling peaks in the first few days and resolves over roughly two to four weeks. Swallowing may feel slightly tight or uncomfortable during this period, and most patients return to desk-type work within about a week. Strenuous activity is usually restricted for several weeks while the implant settles and tissue ingrowth begins.
Rib cartilage grafting adds recovery demands at the chest donor site, usually some soreness lasting a few weeks. A small drain may be placed temporarily to prevent fluid buildup near the harvest area.
Voice safety is one of the most common concerns. Reassuringly, data from the reverse procedure, where thyroid cartilage is surgically reduced, offers some context. In a study of 45 patients who had thyroid cartilage surgery, only four reported any voice changes, and in follow-up no patients reported long-term changes.7PubMed Central. Patient Satisfaction after Aesthetic Chondrolaryngoplasty That data comes from reduction surgery, which involves shaving cartilage near the vocal cord attachments and is inherently riskier to the cords than augmentation. Augmentation works entirely on the outer surface, without approaching the vocal cord attachment points, so the risk to voice function is even lower.
Scarring is the cosmetic concern that shows up most often in patient satisfaction data. In the chondrolaryngoplasty satisfaction study, the scar was the most frequently cited complaint among patients who were less than fully satisfied.7PubMed Central. Patient Satisfaction after Aesthetic Chondrolaryngoplasty Scar healing varies enormously between individuals. People with a history of keloid scarring or hypertrophic scars should discuss this with their surgeon beforehand, as neck scars can be difficult to revise if they heal poorly.
How Cartilage Changes with Age
One aspect of Adam’s apple appearance that rarely comes up is how the thyroid cartilage continues to change over a lifetime. In younger people, the cartilage is relatively flexible. Over the decades, it gradually mineralizes, becoming stiffer and more bone-like. This process happens earlier and more extensively in males, partly because of differences in the protective molecules within the cartilage matrix.2PubMed Central. Gender-specific distribution of glycosaminoglycans during cartilage mineralization of human thyroid cartilage
For someone considering augmentation, this has a few practical implications. In younger patients, the native cartilage is softer, which can subtly affect how an implant or graft is secured. In older patients with more rigid, mineralized cartilage, the surface is firmer and may accept fixation slightly differently. It also means that the natural visibility of the Adam’s apple can shift with age even without intervention, as the cartilage stiffens and the overlying skin thins. Someone in their twenties whose Adam’s apple is barely visible might find it becomes slightly more noticeable by middle age. For anyone seeking a dramatic change, though, the effect of aging alone is far too subtle and too slow to substitute for surgery. It’s a footnote to the biology, not a strategy.
