Surgical head enlargement future?

I keep running into this when I do pubmed searches. I am not interested in having this done but it is interesting.

Although augmentation phalloplasty is not an established procedure, some patients still need enlargement of their penis. Current penile augmentation is girth enhancement of penile body by dermofat graft. We performed this study to identify the efficacy and the patient’s satisfaction of human glans penis augmentation with injectable hyaluronic acid gel. In 100 patients of subjective small penis (Group I) and 87 patients of small glans after dermofat graft (Group II), 2 cm(3) of hyaluronic acid gel was injected into the glans penis, subcutaneously. At 1 y after injection, changes of glandular diameter were measured by tapeline. Patient’s visual estimation of glandular size (Gr 0-4) and patient’s satisfaction (Grade (Gr) 0-4) were evaluated, respectively. Any adverse reactions were also evaluated. The mean age of patients was 42.2 (30-70) y in Group I and 42.13 (28-61) y in Group II. The maximal glandular circumference was significantly increased compared to basal circumference of 9.13+/-0.64 cm in Group I (P<0.01) and 9.49+/-1.05 cm in Group II (P<0.01) at 1 y after injection. Net increase of maximal glandular circumference after glans augmentation was 14.93+/-0.80 mm in Group I and 14.78+/-0.89 mm in Group II. In patient’s visual estimation, more than 50% of injected volume was maintained in 95% of Group 1 and 100% of Group II. The percentage of postoperative satisfaction (Gr 4, 5) was 77% in Group 1 and 69% in Group II. There was no abnormal reaction in area feeling, texture, and color. In most cases, initial discoloration by glandular swelling recovered to normal within 2 weeks. There were no signs of inflammation and no serious adverse reactions in all cases. These results suggest that injectable hyaluronic acid gel is a safe and effective material for augmentation of glans penis.

What hyaluronic acid is:

Ask.com - What’s Your Question?

"Hyaluronic Acid Gel

Another new soft tissue filler on the horizon that is not yet FDA approved but is being studied in the U.S. is a non-animal form of hyaluronic acid gel. Hyaluronic acid is a naturally occurring component of the skin that is the framework or medium that cells live in. In gel form, hyaluronic acid binds to water and provides volume to easily fill in vacant wrinkles left by tissue loss, making it suitable for larger folds of skin around the mouth and cheeks. This highly purified, non-animal form of hyaluronic acid has already been approved for use as a filling agent in Canada, Europe and Australia.

A new multi-center clinical trial has shown this non-animal form of hyaluronic acid gel to be a superior filler to bovine collagen for the persistent improvement of nasolabial folds – the deep lines visible from the nostrils to the corners of the mouth. Six months after treatment was completed, study findings indicated that less volume of hyaluronic acid was needed to achieve optimal cosmetic results, and patients overwhelmingly preferred the gel substance to collagen."

Effects of glans penis augmentation using hyaluronic acid gel for premature ejaculation.

The main limitation of medical treatment for premature ejaculation is recurrence after withdrawal of medication. We evaluated the effect of glans penis augmentation using injectable hyaluronic acid (HA) gel for the treatment of premature ejaculation via blocking accessibility of tactile stimuli to nerve receptors. In 139 patients of premature ejaculation, dorsal neurectomy (Group I, n=25), dorsal neurectomy with glandular augmentation (Group II, n=49) and glandular augmentation (Group III, n=65) were carried out, respectively. Two branches of dorsal nerve preserving that of midline were cut at 2 cm proximal to coronal sulcus. For glandular augmentation, 2 cc of HA was injected into the glans penis, subcutaneously. At 6 months after each procedure, changes of glandular circumference were measured by tapeline in Groups II and III. In each groups, ejaculation time, patient’s satisfaction and partner’s satisfaction were also assessed. There was no significant difference in preoperative ejaculation time among three groups. Preoperative ejaculation times were 89.2+/-40.29, 101.54+/-59.42 and 96.5+/-52.32 s in Groups I, II and III, respectively. Postoperative ejaculation times were significantly increased to 235.6+/-58.6, 324.24+/-107.58 and 281.9+/-93.2 s in Groups I, II and III, respectively (P<0.01). The percentage of postoperative satisfaction in both patient and his partner was 68% (17/25) and 44% (7/16) in Group I, 80% (39/49) and 66% (25/38) in Group II and 75% (49/65) and 62% (32/52) in Group III, respectively. Maximal glandular girth was significantly increased from 9.16+/-0.59 to 10.95+/-0.4 cm in Group II and 8.95+/-0.54 to 11.67+/-0.71 cm in Group III, respectively. These results suggest that glandular augmentation with injectable HA gel is a safe and effective modality to reduce sensory of glans penis. Long-term follow-up for residual volume and efficacy should be requested to establish its precise therapeutic potentials in premature ejaculation.International Journal of Impotence Research advance online publication, 25 March 2004; doi:10.1038/sj.ijir.3901226

OK so some questions:

* Long term is this gel metabolized? If so, loss of circumference over time could be expected, right?
* I’m surprised at zero reported allergic or other negative reactions, and also at the zero reported loss of sensitivity or feeling reports. This stuff has to go somewhere, it stretches things, so I’m surprised that it does not affect how things feel there.
* Does the injected material spread evenly out or is it one big blob that could burst at any time? Yuck?
* It does not seem to be visible by casual examination of the penis head, but still… can anyone tell?
