This site discusses phimosis in its specific forms of phimotic ring, frenulum breve, adhesions or skinbridges. During erection these conditions inhibit the relationship between foreskin and glans. This functionally restricts the erection, and thus has an effect on the sexuality. With our culture's attitudes on health care, it would be appropriate to monitor boys before puberty and encourage early prevention.

2012 : note from author: My previous idea of monitoring boys before puberty is impractical, unecessary and now only of historical interest. please see Postscript.

Modern Treatment

Z plasty for frenulum breve was first reported in 1954

Frenillo de Pene. Plastica con "Z"
(Spanish text)
Frenulum of the Prepuce; "Z" shaped plastic surgery
Rev. argent. urol 23:144-145 Mar-Ap 54 S

In figure 1 the principles of plastic surgery are outlined. The movement of two areas of healthy skin formed by two isocoleses triangles. One is designated with spots the other with stripes. By moving the free extremety of point B to point B', at the same time the other extremity A automatically moves to A' As a result of this transposition the skin areas obtain a greater vertical diameter and a zig zag scar.

Figure 2 shows the geometrical application on an area of skin whose folds run transversally, where a scar line (CICATRIZ) cuts them perpendicularly. To correct this scar line it is necessary to divide and divert this straight vertical line. The most effective way of doing this is the "Z" as described above.

Applying this method to the frenulum of the penis has given excellant results (figures 3 and 4) without any cases being unsuccessful or needing to be repeated. Notice that in figure 4 the vertical cut is hidden in the preputial fold and that the slanting cuts lie independantly on the glans and prepuce.

Z Plasty for Short Frenum of Prepuce of Penis
Ann Plast Surg 1991 Feb;26(2):196-7
"Z plasty for short scarred frenum of prepuce of penis is presented as a useful new technique."
"Previously we used to perform circumcision or frenoplasty with a transverse incision sutured vertically to treat this condition. Circumcision, however, was thought to be too big a procedure for this condition, and transverse incision sutured vertically did not give a satisfactory result. Hence a Z plasty was performed on the patient presented."

"The two triangles slid very easily, and suturing was done with 6-0 chromic catgut. The result was very satisfactory. The patient had satisfactory sexual intercourse 15 days after operation."

Lysis of frenum
Urology 1979 Feb;13(2):195
"Lysis of the frenum may be utilised. ... ... A disposable battery-operated cautery device has been found to be useful and efficient for the lysis. The frenum, while on tension, is incised with the glowing tip of the cautery. Small superficial vessels and bleeding points may be immediately coagulated. ... The sides of the incision may be approximated with fine absorbable suture ... "

Elongación del frenillo balanoprepucial con una técnica muy sencilla - (Spanish text)
Elongation of the balano-preputial frenulum using a very simple technique
Arch Esp Urol 1990 Jan-Feb;43(1):78-9
"Abstract - A new technique to achieve, elongation of frenulum is described. The procedure is simple, exsanguine, and can be performed quickly. The results obtained with this procedure is similar to those obtained with traditional techniques."

"1. Anaesthetic injection at the base of the frenulum. 2. The placement of two vascular clips as shown in figure 1." (one under the glans, the second parallel near the foreskin. 3. Section of the frenulum as in figure 2 and pulling the end of the clips away from each other) "4. When the frenulum is stretched as shown in figure 3, it is covered with a dressing for twenty four hours."

"The operation took place without bleeding and in no case took longer than five minutes. The clips released spontaneously after three or four days."

During a description on a possible preparatory step for circumcision: ... "a second incision is marked, following the outlines of the corona and the V of the frenulum on the ventral side. The frenulum usually retracts into a V. In some cases, the frenulum can be lengthened by closing the edges of the V in a longitudinal orientation for a short length (frenuloplasty). If frenoplasty is done, the proximal incision does not need to follow the V of the retracted frenulum in that the ventral skin is straight"

EMLA cream anaesthesia for frenuloplasty
Br J Urol 1995 Nov;76(5):653-4

"Abstract - Objective: To evaluate the use of a eutectic mixture of local anaesthetics (EMLA) cream as the sole anaesthetic for frenuloplasty. Patients and Methods: Fifteen patients . were given topical EMLA cream 30 min before frenuloplasty; a Tegaderm dressing was applied to keep the anaesthetic in place. The level of anaesthesia was assessed on arrival in theatre using pin-prick testing and the patients were asked to grade their level of pain ...
Results: Fourteen patients had pain scores of zero and were fully anaesthetized during the procedure. One patient's Tegaderm dressing was displaced soon after application and he was inadequately anaesthetized on testing, ... and required infiltrative lignocaine ...
Conclusions: EMLA cream is a well-tolerated and reliable anaesthetic for frenuloplasty. Using a condom to keep the cream in place would reduce the small failure rate associated with the displacement of the Tegaderm dressing."
