Aim: The extended running W-plasty technique using the W-plasty principle is a modification of the conventional technique. The use of this technique was utilized for simultaneous reduction of the protuberant labia minora and the redundant clitoris.
Methods: Twenty-three patients presented to the plastic surgery clinic between 2008 and 2015 with the complaints of protuberant and enlarged labia minora in conjunction with a hypertrophied clitorial hood. The extended running W-plasty was performed in all patients. Surgery was performed under general anesthesia as an outpatient procedure with a range of operative time from 30-45 min. The Likert scale was used to evaluate outcomes.
Results: Patients maintained labial length with decreased scarring. Small hematomas occurred in 2 patients and were treated conservatively. One case of wound dehiscence occurred and was also treated conservatively. Patients returned to normal activity 5-7 days postoperatively. The cosmetic outcome of all patients was very satisfactory.
Conclusion: The running W-plasty technique is ideal for closure of secondary defects following excision of both the redundant labia minora and clitoral hood, while maintaining length and providing tensionless scars. The technique conserves the original tissues while avoiding over- or under- resection of the labia.
Extended W-plasty, labia minora, clitoral hood reduction
Repeated tearing and stretching caused by childbirth, aging, and sexual intercourse, in addition to congenital defects such as vaginal atresia and Müllerian agenesis, and gender switching play a role in the request to change the size of the labia minora. Congenital hypertrophy of the labia minora has also been reported. Maas and Hage reported the use of a W-shaped resection of the protuberant labia minora in 13 patients. Later, Solanki et al. applied the same technique to 12 patients. Both groups of authors noted that the running W-shaped resection technique avoids many potential problems which can occur with other techniques. Capraro introduced the edge resection technique in which the labia is resected at its free edges. Hamori preserved the natural rugosity by performing the central wedge technique. De-epithelialization is another tool which has been used to reduce the size of the labia, and can be performed with either a scalpel or the CO2 laser. Gonzalez et al. reported the use of the custom flask labiaplasty technique in 50 patients, which permits precise reduction of the labia minora. Ostrzenski described a fenestration labiaplasty technique in which the inferior flap is transposed to reduce the height and width of the labia.
The primary goal of the extended running W-plasty technique, described in this study, is to achieve an acceptable protrusion of both the labia minora and the clitoral hood beyond the labia majora. The design reported in this study is a modification of the conventional W-plasty reported in the literature which is used for reduction only of the hypertrophied labia minora.
Six patients with unilateral hypertrophy and 17 patients with bilateral hypertrophy of the labia minora presented for evaluation [Figure 1].

Within this group, 8 patients complained of irritation and chronic infection while the remaining 15 patients were concerned with the noticeable protrusion of the enlarged labia minora and its associated psychological and emotional distress.
Patients were admitted to the same day surgery unit after a complete examination. General endotracheal anesthesia was used in all patients. The procedure commenced with marking the running W-plasty on both sides of labia minora with an extension through the clitoral hood [Figure 2]. Excision of the pre-determined amount of tissue was performed [Figure 3], followed by meticulous hemostasis and closure of the interdigitating small triangular flaps with absorbable 4-0 monofilament [Figures 4 and 5].

A compression dressing was applied for several hours and removed prior to discharge. At the postoperative visits, an outcome evaluation questionnaire based on a 5-point Likert scale was administered. The questionnaire evaluated the level of improvement in physical exercise, improvement in sexual intercourse, improvement in appearance and shape of the labia minora and clitoral hood, elimination of fungal infection, ability of patients to wear fitted undergarments, and improvement in sense of well-being.
A 5-point Likert scale was designed with options of 1 (very dissatisfied), 2 (dissatisfied), 3 (moderately satisfied), 4 (satisfied), and 5 (highly or very satisfied).
The preoperative and postoperative photos were analyzed based on the extent of external genitalia exposure and analysis was performed by an independent plastic surgeon.
Because the W-plasty technique conserves tissue, over-resection was avoided, and the shape and size of the labia minora were acceptable in all patients. In addition, the vertical length of the labia was preserved. All patients were noted to have symmetry with a and natural color and contour of their labia minora [Figure 6].
Small hematomas occurred in one patient and were treated conservatively. Wound dehiscence (1-2 cm in length) developed in one patient and was also treated conservatively [Table 1].

Based on the results of the Likert scale and the evaluation questionnaire [Table 2] provided during the follow-up period, the aesthetic outcomes were very satisfactory in all patients. Patients experienced improvement in their daily activities, including sexual intercourse and physical exercise. Hygiene became easier, and patients stated that they did not need to apply antifungals or local steroids after surgery. All patients were able to wear bathing suits without embarrassment. No patients experienced scar numbness, sensitivity, or scar pain during intercourse.

The use of the extended running W-plasty technique is required for the simultaneous reduction of hypertrophied labia minora and prominent clitoral hood. The central wedge resection removes a full-thickness wedge of skin from the thickest portion of the labia minora. Giraldo et al. add a 90-degree Z-plasty to the central wedge procedure; this modification produces a refined surgical scar that is less tethered and has less tension. The W-plasty previously described by Maas and Hage and Solanki et al. is limited as it does not simultaneously address the redundant hood of the clitoris.
The technique described in the current report addresses both the hypertrophied labia and clitoral hood with an appropriate skin resection. The extended W-plasty has the same principles of the conventional W-plasty in thatthe angles of the “W” vary between 50 and 55 degrees, but are further extended to involve another aesthetic unit which includes the defect resulting from the reduction of the enlarged clitoris. The technique divides the scar into small triangles to break up the scar contracture and providing a more level surface to the scar.
In the current study, the most common reason for seeking reduction of the labia minora (13 out of 20 patients) was dissatisfaction with the appearance of the labial and clitoral hood. Hong et al. reported the use of both the central wedge resection and asymmetric Z-plasty techniques in order to avoid the linear scar. De-epithelialization of the skin of the central region of the medial and lateral aspects of each labia minora reduces the excess vertical tissue, while preserving natural rugosity and the sensory and erectile abilities of the labia. One disadvantage of de-epithelialization is that the width of the individual labia can increase if a large area of labial tissue is de-epithelialized. Although de-epithelialization by laser treatment has been reported, it presents the potential for the occurrence of epidermal inclusion cysts. Closure of the opposing W-shaped incisions results in a tensionless zigzag suture line running obliquely across the edge of the labium.
In this study, the running W-shaped resection technique avoids many potential problems which can occur with other techniques, including wound contracture and dehiscence. The extended running W-plasty technique is ideal for closure of the secondary defect created following excision of both the redundant labia minora and the redundant clitoral hood because it maintains the vertical length and provides tensionless scars. The reduced labia minora remains sensate and painless. This technique avoids the over- or underresection of the labia, and all patients in our series were relieved of the functional problems related to an enlarged labia minora and clitoris.
In conclusion, the extended running W-plasty technique is a viable alternative to the conventional W-plasty, central wedge resection, edge resection, de-epithelialization excision, laser de-epithelialization, and other techniques. It is a modification of the W-plasty design reported in literature, and can be used to simultaneously reduce both the hypertrophied labia minora and the redundant clitoral hood.
