This narrative review aims to explore and evaluate the various techniques available for penile lengthening that can be performed concurrently with inflatable penile prosthesis (IPP) insertion. We conducted a comprehensive examination of the literature, utilizing PubMed focusing on key terms such as \"penile prosthesis corporal length\", \"inflatable penile prosthesis and short penis\", and \"buried penis\". The review identified several advanced methodologies for preserving and enhancing penile length during IPP insertion. These techniques include subcoronal IPP insertion, sliding technique, modified sliding technique, multiple slice technique, and circumferential incision with grafting. Supplementary procedures aimed at improving the perception of increased length involve ventral phalloplasty and suprapubic lipectomy. It is worth noting that the maximum length gain seems to be constrained by the length of the neurovascular bundles. In summary, the evidence available in the literature is limited due to the short of case series reported, lack of randomized controlled trials, and heterogeneity of the studies.
