Hi Smalljay,
I will try to explain it much better :- This korean Dr. studied the anatomy of the penile glans very well ; he found that the penile glans contains 3 parts with different thicknesses :-
1- The outer layer is \"the Epithelium\" with a thickness not more than 1mm ---> so injecting the dermal filler superficial under the epithelium (i.e. between the epithelium and the lamina propria ---> it will cause lifting the epithelium) ---> unpleasant, unnatural, flowered, shiny or rough (or even epidermal necrosis in rare cases) with a shorter period result. You can see this unpleasant result in the 2nd pic. of the glans in the following site :-

2- The middle part is \"the Lamina Propria\" this is the most important one in regard of glans enlargement with a thickness range from 1mm at the corona of the glans to 2.5 mm at the periphery i.e. around the opening of the urethra ---> injecting the dermal filler in the central area of the Lamina Propria ---> The best esthetic with a longer result.
3- The inner part is \"the Corpus Spongiosum\" ---> into bloodstream ---> dangerous ---> Emboli ??
So the idea of Glans enlargement is how we can expand the Lamina Propria uniformly and to get an augmented Glans with a natural shape ---> Is by injecting the filler (at a tilted angle) into the central area of the Lamina Propria. So he found that the best way is to insert the needle in the central area of the thickest part of the Lamina Propria i.e. around the opening of the urethra and not at the corona (which has the thinnest lamina propria) and the doctor should feel always pressure resistance during the injection of the filler i.e. he is in the right place (otherwise the injection of the filler will be into the corpus spongiosum).
In Summary :-
* The old technique (conventional) where they insert the needle at the corona (where thinnest L.P. is) ---> the chance the filler will be outside the Lamina Propria is high ---> the chances of flowered glans (due to superficial injection i.e. under the epithelium) or emboli (due to deep injection i.e. into the C.S.) results are high.
* His new technique where he inserts the needle around the opening of the urethra (where thickest L.P. is) ---> i.e. the chance the filler will be inside the Lamina Propria is high ---> Lamina Propria expansion ---> the chance of a pleasant and a natural shape augmented glans result is high.
