Darshani- I think you may have a confusion about anatomy, and what you are seeing is not surgical- but NORMAL anatomy, or perhaps not quite normal anatomy. The sides of the uthreal opening are called "meatal lips" that term in itself tells you that anatomist do not see the opening as a drilled hole- but a gap between two fleshy places coming together.
If you study about how our genitals are formed- the fetus stars out with female genitals and if it is to become a boy- the two halves of the girl parts seal up as the penis grows- so the underside of the penis has a seam (it's called the raphe and can be seen- expecially on the testicals- but sometimes on the shaft too)
On some boys the closure is incomplete- this is called Hypospadias- this can be very severe, or the incomplete colosure can be high up on the shaft- near the testicles... or sometimes it is simply a very large slit at the glans- rather than a hole. It is possible that your husband has a mild case of hypospadias.
These website has some pictures of babies and two adults with different forms of hypospadiashttp://www.circumstitions.com/Images...y/hypospa2.jpghttp://www.meddean.luc.edu/lumen/Med...y/abnpendv.htm
In some cases hypospadias is inherited, so you might want to find out if your husband has any relatives who also had it... but it would be unlikely. It is also possible that he was never told that he or anyone else in his family has hypospadias... he may not even know that his penis does not look like everyone else's... so please tread lightly!! If you do happen to have a son with hypospadias- circumcision is an absolute NO NO... if he choses to have corrective surgery as an adult he might want to use his foreskin (or some of it) to reconstruct the penis.
10% of circumcised boys get a condition called meatal stenosis which is a narrowing of the opening due to scar tissue building up.http://www.emedicine.com/ped/topic2356.htm
This is corrected surgicly with an operation called meatotomy (sp?) Although the procedure sounds rather uncomplicated (outpatient) I have never heard of anyone who had actually had this done... either people keep this very hush hush, or as I suspect hardly any boys with meatal stenosis are diagnosed or treated and they have to suffer with problems peeing because no one even knows to look for the signs.
I hope that helps,
