Amniotic Membrane Graft in the Management of Complex Vaginal Mesh Erosion

Vaginal mesh erosion is a devastating complication after pelvic floor mesh surgery and it can be treated conservatively or with surgical revision. However, the management options following a failed primary revision or complex vaginal erosions are very limited. The aim of this study is to describe a novel treatment using an amniotic membrane as an inlay graft for such patients. Eight patients who failed conservative or primary surgical revision were enrolled. The complex erosions included vaginal agglutination, multiple vaginal erosions, recurrent erosions, and mesh cutting through the urethra. We used an amniotic membrane as a graft to cover the vaginal defect after partial excision of the mesh erosion and we describe the technique in this study. There were no intraoperative complications and none of the patients reported any further symptoms at a mean of 27 months follow-up. Only one patient had recurrent erosion, however, the erosion size was narrower and was subsequently successfully repaired. No further vaginal mesh erosions were noted in the other patients who all had good functional recovery. The use of an amniotic graft can be an economic and alternative method in the management of complex vaginal mesh erosions.

Amniotic membrane graft in a recurrent re-fusing temporal tarsorrhaphy: a case report

Amniotic membrane grafts (AMGs) are commonly used to treat a variety of ophthalmologic conditions. Complications exist with permanent tarsorrhaphies, including the risk of re-fusion following tarsorrhaphy separation. We report a novel application of amniotic graft in lieu of skin grafts to protect the exposed marginal surface during the initial re-epithelialization period following release of a permanent tarsorrhaphy. We present a 24-year-old man who sustained an 80% total body surface area burn from a motor vehicle accident 16 months prior to presentation at our Oculoplastic service for evaluation of residual lagophthalmos. His original permanent tarsorrhaphies were removed; however, re-fusion occurred temporally in both sides. During a second attempt, AMGs were secured over the eyelid margins, leading to a successful tarsorrhaphy takedown without re-fusion. Periocular burn injuries present particular challenges, as cicatricial changes continue to evolve and viable skin graft areas diminish with each successive graft. In the setting of recurrent auto-tarsorrhaphy, the AMG has shown to be a viable alternative to standard skin grafting. This case demonstrates excellent results in a skin graft sparing procedure that is effective and efficient. Amniotic membrane grafting reduces morbidity by foregoing skin graft donor sites and can achieve similar functional and cosmetic results to standard skin grafting with reduced overall surgical time. As such, AMGs have the potential to supplant standard skin grafting in cases of recurrent auto-tarsorrhaphy, particularly in the setting of diminished available healthy skin tissue.
