Objective: To describe our surgical technique and outcomes of glans augmentation with autologous adipodermal or acellular dermal matrix (ADM) interposition grafts for fat atrophy of the neophallus following penile implant insertion.
Methods: We retrospectively reviewed the outcomes of glans augmentation in phalloplasty patients presenting with fat atrophy following penile prosthesis insertion. Glans augmentation is performed by making a small posterior coronal incision to preserve the shaft-to-glans dermal blood supply. A plane is made between the glans skin and the capsule of the distal penile implant cylinder. An adipodermal graft or ADM sheet graft is then sized to the glans dissection space and inserted, covering the implant capsule and filling the glans. The graft harvest site and posterior coronal incisions are then closed. The primary postoperative outcome was the recurrence of implant glans skin impingement or erosion.
Results: From October 2017 through January 2023, 15 patients underwent glans augmentation after penile prosthesis insertion. The mean follow-up was 20 months. Adipodermal grafts were placed in 12 (80%) patients and ADM grafts in 3 (20%) patients. Two patients developed complications requiring surgical revision and 3 patients are considering a secondary glans augmentation, for a potential surgical revision rate of 33% (5/15). There were no wound infections, implant infections, or erosions.
Conclusion: Glans augmentation with adipodermal or ADM graft interposition between the glans skin and implant capsule improves the neophallus appearance and may help prevent future implant erosion in phalloplasty patients who develop fat atrophy after penile implant insertion.

Introduction: Distal anterior urethral strictures (DAUS) affect the meatus, navicular fossa (NF) and penile urethra (PU). The main causes are inflammatory (lichen sclerosous [LS]), traumatic iatrogenic, or idiopathic. Post-hypospadias stenosis is common and constitutes a separate entity, dealt with in a separate article.

Background: Hypospadias with lichen sclerosus (LS) poses surgical challenges due to lack of materials for urethral reconstruction and coverage and the limited number of reports on this clinical condition.
Objectives: To report surgical strategies and outcomes for primary and redo hypospadias patients with LS.
Materials And Methods: We conducted a retrospective observational descriptive study with 31 patients with primary/redo hypospadias and LS between 2013 and 2023.

Article Synopsis
- Meatal stenosis and fossa navicularis strictures are often caused by lichen sclerosus and surgical procedures, and a new graft technique was evaluated for their reconstruction.
- This study involved 26 patients who underwent a specific surgical method, focusing on preserving the glans cap and using a dorsal inlay graft, with patients monitored for symptom relief and urinary function post-surgery.
- Results indicated that while there were a few complications, most patients experienced significant improvements in symptoms and urinary flow after the procedure, making this technique a promising option for managing these conditions.
