Objective: To evaluate the postoperative complications, the appearance and motility in patients who underwent placement of Medpor orbital implant after enucleation, or secondary implantion.
Methods: A retrospective study was carried out on the 266 cases in whom a Medpor orbital implant was implanted from 2001 to 2004.
Results: All the cases were followed up from 3 to 26 months. A total of 23 in 266 (8.6%) cases had documented postoperative complications: inflammatory granuloma in 2 cases (0.8%), and moderate or severe ptosis in 4 cases (1.5%), and remained upper eyelid notch with mild ptosis in 8 cases (3.0%), and lower eyelid laxity in 2 cases (0.8%). In 5 cases (1.9%), implant exposure developed: 3 cases were resolved with conservative therapy, and 2 cases with surgical revision of the socket. 2 cases experienced persistent pyogenic discharge in conjunctival sac, and the implant was took out because the discharge couldn't control with local and systemic antibiotic therapy. The motility is excellent in 148 cases and good in 11 cases after the primary obital implant, and excellent in 36 cases and good in 68 cases and bad in 3 case after the secondary implant. The difference between the primary and the secondary obital implant is obvious.
Conclusions: It is considered that Medpor orbital implant is a good method of ocular plasty. Although there are some mild postoperative complications, but those can be resolved with conservative therapy or surgical revision. Medpor orbital implant has good histocompatibility, and the operative processes are convenient. Patients are satisfied with appearance and motility. So the Medpor orbital implant is one of the best selection in ocular socket plasty.

Objective: To evaluate the impact of Medpor implantation on extraocular muscle function, eye movement disorders, and diplopia in patients with orbital wall fracture.
Methods: A retrospective study was conducted on 98 patients (98 eyes) who underwent Medpor implantation surgery at Bethune International Peace Hospital from January 2019 to December 2022. The degree of eyeball enophthalmos and total fracture area in patients before and after surgery, as well as orbital volume were measured.

Article Synopsis
- - The paper discusses using a new method for fixing zygomatic malposition and orbital floor fractures with hydrated acellular dermal matrix (ADM) after traditional implants failed for a 27-year-old woman with ongoing facial issues from trauma.
- - The surgery used ADM for volume correction and structural support, successfully addressing problems like enophthalmos, facial contour depression, and restoring the patient’s facial symmetry and eye functionality.
- - Results showed that this ADM method is a reliable alternative to standard bone grafts and implants, paving the way for its broader use in complex facial reconstructive surgery after trauma.

Article Synopsis
- * The surgery involved a collaboration between head and neck surgeons and oculofacial plastic surgeons, employing techniques like canthotomy and orbitotomy for tumor excision and reconstruction with a Medpor implant.
- * Post-surgery, the patient showed positive healing progress with no visual issues, and the coordinated approach ensured both aesthetic and functional restoration of the midface, achieving near symmetry in facial structure.

Article Synopsis
- The study aimed to evaluate the effectiveness and safety of a new surgical approach combining medial orbital wall osteotomy with the implantation of Medpor material for treating orbital hypertelorism.
- Researchers conducted a retrospective analysis on patients who underwent this surgery from 2010 to 2019, assessing long-term outcomes and any surgery-related complications.
- Results showed that all four patients (3 males, 1 female) were satisfied after 24 months, with no serious complications such as vision loss or implant rejection, indicating the procedure's safety and effectiveness.
