The orbit is a confined space with a defined bony structure. Bony protrusion into the ethmoid or maxillary sinuses by the blowout fracture can displace orbital tissues, including rectus muscles and adjacent fascial septae. Especially, reconstructing the orbit’s floor and medial wall can be challenging when the inferomedial strut or posterior bony ledge is affected, leading to a loss of critical anatomic landmarks and support. Correctly positioning an implant in the precise anatomic location can be challenging. Recent updates to the navigation system have addressed this issue. Despite its early application, using a navigation system in these orbital fractures advances plastic surgeons in a way that has more confidence and accuracy in surgical planning. The video demonstrates how these 2 can be combined in an operating room. Intraoperatively, the authors check the superior, anterior, and posterior ends of the medial wall fracture and the posterior end of the floor fracture. A single orbital implant was trimmed and reshaped to match defect measurements. The implant placement was meticulously executed to repair the fracture while ensuring the inferior oblique muscle was not injured. After confirming the correct placement of the implant, it was secured to the inferior orbital rim using a single screw. Depending on the medial orbital wall fracture depth or degree of soft tissue herniation, the authors used an artificial dermal matrix or trimmed absorbable mesh plate to cover the uppermost part of the medial wall fracture to prevent postoperative enophthalmos. Finally, a forced duction test was performed. Our study shows that navigation-assisted inferomedial orbital wall reconstruction using materials readily available in the market is safe and effective.

“…There are different materials available for reconstructing the orbital wall after a blowout fracture, but based on our experience, titanium-reinforced porous polyethylene (TR-PPE) plate has the strongest qualities [11][12][13][14]. If the inferomedial wall fracture is severe, additional materials may be used in combination, but the primary reconstruction should always be done with a rigid and fixable material.…”

Background: Little attention has been paid to combined orbital floor and medial wall fractures with the involvement of the inferomedial orbital strut. Managing this particular fracture can prove challenging. However, various innovative techniques have been introduced to assist with the process. Our study focuses on sharing our approach to orbital wall reconstruction using navigation guidance and titanium-reinforced porous polyethylene plates, specifically cases involving the inferomedial orbital strut. We believe that implementing a navigation system can effectively lead surgeons to the fracture site with utmost safety. Also, we hypothesized that this navigation system is beneficial to use singe fan titanium-reinforced porous polyethylene plates with orbital wall fractures involving IOS while minimizing possible complications. Methods: We retrospectively reviewed 131 patients with medial orbital wall and orbital floor fractures with or without combined other facial bone fractures who underwent orbital wall reconstruction by a single surgeon from May 2021 to May 2023. Amongst, we identified fourteen orbital wall fractures involving the inferomedial orbital strut. We used a subciliary incision as the only approach method for performing titanium-reinforced porous polyethylene plates for navigation-guided orbital wall reconstruction. Patients were followed up for at least three months. Results: All cases were effectively resolved using titanium-reinforced porous polyethylene plates. There were no complications during the patient’s complete recovery, confirmed clinically and radiologically. Based on the serial CT results, it was discovered that implanted titanium-reinforced porous polyethylene plates successfully covered the defect. Conclusion: Based on our retrospective analysis, it has been determined that among the 131 recorded cases of orbital fractures, 14 of them (or 10.7%) involved the inferomedial orbital strut. Navigation-guided reduction using titanium-reinforced porous polyethylene (TR-PPE) plates can lead to predictable, reliable, and excellent outcomes for treating orbital fractures involving the inferomedial orbital strut without complications.

“…ADM is a three-dimensional extracellular matrix framework derived from the skin that serves as a reparative material. Although initially used in patients with severe burns, ADM has recently gained widespread application across various clinical fields including plastic surgery, breast surgery, head and neck surgery, otolaryngology, urology, oral surgery abdominal wall reconstruction gynecology and ophthalmology (71)(72)(73)(74)(75)(76)(77). ADM has gradually become a popular choice for urethral repair and reconstruction in tissue engineering.…”

The management of severe urethral stricture has always posed a formidable challenge. Traditional approaches such as skin flaps, mucosal grafts, and urethroplasty may not be suitable for lengthy and intricate strictures. In the past two decades, tissue engineering solutions utilizing acellular dermal matrix have emerged as potential alternatives. Acellular dermal matrix (ADM) is a non-immunogenic biological collagen scaffold that has demonstrated its ability to induce layer-by-layer tissue regeneration. The application of ADM in urethral reconstruction through tissue engineering has become a practical endeavor. This article provides an overview of the preparation, characteristics, advantages, and disadvantages of ADM along with its utilization in urethral reconstruction via tissue engineering.
