All, then, that is requisite to remedy this condition in the first instance, is the due separation of the two contiguous layers of muco-cutaneous membranes, which in the new-born may generally be effected with ease. As the infant grows, however, there is apt to supervene relative disparity of size; the tissues cannot be sufficiently expanded to allow of the ideal state of the organ--a prepuce movable freely and loosely upon its included glans--without some laceration. And, unless care be taken, the wounds in the parietal layer of muco-cutaneous membrane again quickly heal; the new cicatricial tissue undergoes, perhaps, a little real contraction; and matters remain as they were before. Hence, probably, the disfavour with which procedures, involving dilatation of the prepuce, seem to have been hitherto regarded by most surgeons.[22] Some amount of reunion between the two surfaces may also take place at the spots where the adhesions have been ruptured. The principle to be aimed at, however, is simply the separation of two contiguous and adherent layers of mucous or muco-cutaneous membrane. Few medical men are probably aware of the natural distensibility of the parts; of the ease with which (when the patient is rendered passive and unconscious by means of an anæsthetic) the glans can be brought completely into view, and the prepuce perfectly retracted behind the corona. All that is then necessary is, by the use of emollients and by daily retraction for a very brief period, to prevent reunion of adhesions or of fissures in the muco-cutaneous membrane; until a sufficient degree of dilatation has been secured to preclude all fear of any future difficulty. Certain precautions are, of course, necessary. The patient should be anæsthetised; the tissues involved are extremely sensitive, and the administration of ether (or of chloroform in the case of a young child), besides relaxing the parts, enables the measure to be carried out much more efficiently than would otherwise be the case. Although the necessary dilatation can usually be very speedily effected, it often takes some little time thoroughly to remove the adherent smegma, not seldom of gritty and calcareous consistence. This, besides being the longest, is the most painful part of the manipulation. The use of cocaine as a local anæsthetic for such a purpose, precluding the administration of ether or chloroform, is not to be recommended. The wide surface involved renders its influence incomplete; and it is of considerable advantage to have the patient, particularly when of tender years, oblivious to what is going on.[23]
