Phalloplasty is a complex, multi-stage reconstructive procedure, most commonly performed as gender-affirming surgery. The process involves creating a neophallus using tissue transferred from a donor site on the body. This article examines the physical, functional, and long-term psychological outcomes patients can expect, which are a direct consequence of the surgical techniques and the patient’s specific goals.
Achieving the Desired Aesthetic and Structural Results
The final appearance of the neophallus depends significantly on the chosen donor site. The radial forearm free flap (RFF) often yields good cosmetic outcomes and a thin, pliable structure. Alternatively, the anterolateral thigh (ALT) flap may provide greater length and girth, and the resulting scar is easier to conceal. The overall size typically falls within the range of 5 to 6 inches in length, and the neophallus maintains the same size whether flaccid or rigid, unlike a natal penis.
Aesthetic refinement procedures are often performed to enhance the structural result. Glansplasty, or coronaplasty, shapes the tip of the neophallus to create a contoured, circumcised appearance. This procedure contributes to the final aesthetic goal and can be further refined with medical tattooing to add color and definition. Scars are an unavoidable part of the outcome, appearing at the donor site and along the shaft of the neophallus itself.
The structural result also includes the ability to stand to void, which requires the successful lengthening of the urethra through the neophallus (urethroplasty). This is a major goal of the surgery for many patients. Achieving a satisfactory aesthetic result often involves multiple stages, allowing time for healing and for the tissue to settle and mature. The final appearance emerges over the entire staged process, not immediately after the initial operation.
Functional Outcomes: Sensation, Erection, and Voiding
Functional results are a primary concern for patients, involving sensation, the ability to achieve rigidity, and urinary function. Sensation is a complex and gradual result, with different types of feeling returning over time. Successful techniques, such as the radial forearm free flap, connect donor nerves to recipient nerves, facilitating the return of tactile and sometimes erogenous sensation.
The recovery of sensation is variable; light touch and deep touch often return first, followed by the slow return of erogenous sensation, which can take many months to a year or more. The nerves that enable orgasm are typically preserved and connected to the neophallus, allowing for the potential to achieve sexual pleasure. A high percentage of patients report some degree of sensation in the phallus after the procedure.
Phalloplasty does not create inherent erectile function because the neophallus lacks the native erectile tissue necessary for rigidity. To achieve a functional erection for penetrative sexual intercourse, a separate procedure is required to implant a penile prosthesis. Patient satisfaction with the erectile prosthesis outcome is high, despite the complication and revision rates associated with the implant procedure.
The ability to void while standing is a highly desired functional outcome, achieved through the creation of a neo-urethra during urethroplasty. While many patients successfully gain this ability, the urethroplasty stage carries a high risk of complications, most commonly urethral strictures and fistulas. Complication rates are significant, often requiring one or more revision surgeries to achieve a stable and functional result. Despite the need for revisions, over three-quarters of patients are ultimately able to void while standing.
The Multi-Stage Process
The aesthetic and functional results of phalloplasty are realized through a series of planned surgical stages, not a single operation. This staged approach is necessary to allow for tissue healing, blood supply stabilization, and complication management. The overall process often spans 12 to 18 months, but the timeline can extend if complications occur or if the patient needs to schedule around life commitments.
The typical staging process begins with the initial phalloplasty, forming the shaft of the neophallus and often including the creation of the neo-urethra. Subsequent stages focus on refinement and the addition of components, such as glansplasty, scrotoplasty, and the insertion of testicular implants. The final functional result, such as the insertion of a penile prosthesis, must wait until the neo-urethra has fully healed and is functioning without complications.
Each stage requires a recovery period, typically three to six months between major operations, to ensure the wound is fully healed and the outcome is stable. The cumulative result is a product of this long-term commitment, where each successful procedure builds upon the last. Addressing complications, such as urethroplasty revisions, can add additional stages and time before the final results are complete.
Long-Term Psychological and Quality of Life Results
The ultimate measure of phalloplasty’s success lies in its long-term impact on the patient’s psychological well-being and quality of life. The procedure is consistently associated with a significant reduction in gender dysphoria by aligning the body with the patient’s gender identity. This improved body congruence often leads to enhanced self-confidence and a more positive self-image.
Studies on post-surgical patients report a strong improvement in overall quality of life. A majority of patients report a marked improvement and express that they would undergo the same treatment again. The positive outcomes extend to social and intimate aspects of life, including improvements in dating life, social interactions, and sexual function.
The psychological benefits are further demonstrated by the positive effect on mental health, with self-reported improvements in conditions like anxiety, depression, and social phobia. High patient satisfaction rates underscore the life-altering value of achieving the desired physical and functional outcomes. The ability to live authentically and confidently is the most profound long-term result of a successful phalloplasty.
