Abstract
INTRODUCTION AND OBJECTIVE: Many men often have the need to enlarge their penises for psychological gain and to satisfy or to impress their partners. Many surgical techniques have been reported. However, none is the gold standard. AIM: To evaluate the efficacy and safety of human acellular dermal matrix allograft in augmentation phalloplasty technique. METHODS: From March 2015 to September 2017, a total of 182 patients were prospectively recruited into our cohort after complete physical and psychological evaluation that deemed suitable for penile enhancement. Penis circumference was measured at the mid-length of the penis. Mean was 7.03 cm (6.93 ± 1.00 cm) and 12.1 cm (10.59 ± 1.15 cm) during flaccid and erection, respectively. All patients received human acellular dermal matrix graft under spinal or local anesthesia. The allograft was preconditioned in normal saline for 20 minutes, and mesh incisions were made to optimize blood flow. The width was equal to the circumference of both corpus cavernosa but without corpus spongiosum. The length of the graft was determined by measuring the length between the tip of the coronary sulcus and the root of penis. A complete incision below the coronary sulcus to the depth of the Buck's fascia was made. Then separate the dartos fascia from the Buck's fascia. The prepared graft was then placed on top of the Buck's fascia, with the blood-remained side facing the Buck's fascia. The graft was sutured using 4-0 absorbable polyglycolic acid suture to the Buck's fascia. Extra caution needed to be taken when fixing ventrally to avoid injuring the urethra. Once completed, the dartos fascia was restored, the dartos fascia and subcutaneous tissue were sutured with 4-0 absorbable suture, and skin closure is achieved subsequently. RESULTS: The post-operative course was without complications. At the follow-up after 1 year, the mean flaccid girth increased to 8.07 ± 1.06 cm (P < .05), while the mean erect girth increased to 12.79 ± 1.23 cm (P < .05). Sexual activity was allowed after 8 weeks of surgery. The majority reported that sexual self-esteem and functioning significantly improved. In addition, 59 patients reported alleviation of premature ejaculation. CONCLUSIONS: Compared to autologous dermis-fat graft and xenograft, augmentation phalloplasty using human acellular dermal matrix has several advantages: (1) it avoids harm harvesting site of the autograft; (2) the effects of dermis allograft can last at least 1 year; and (3) acellular dermal matrix is more likely to be accepted by people.
