‘Frozen Eye’ ? Post Blowout Fracture Surgical Correction ? A Case Report

The Rationale: “Frozen Eye” is a very uncommon sequel after treatment of orbital blowout fractures requiring implant placement. Patient Concerns: The implant may faultily impinge on the ocular and extra?ocular muscle(s), causing the abnormality in the movement of the eye. Diagnosis: We present a 56?year?old male whose ocular implant impinged on muscle, causing “frozen eye” and had an infected implant. Treatment Outcomes: The same was removed and surgically corrected. The manuscript describes the details and discusses the possible mechanism that led to the “Frozen Eye”

Mechanical study of polyurethane elastomer and Medpor as the material of artificial auricular scaffold / 中国修复重建外科杂志

Objective: By comparing the mechanics of human auricular cartilage, polyurethane elastic material, and high density polyethylene material (Medpor), to produce theoretical proof on choosing optimal artificial auricular scaffold materials. Methods: The experimental materials were divided into 3 groups with 6 samples in each: the auricular cartilage group (group A), the polyurethane elastic material group (group B), and the Medpor group (group C). With an Instron5967 mechanical testing machine, compression and tensile testing were performed to respectively measure values of compression parameters (including yield stress, yield load, elastic modulus, yield compressibility, compressibility within 2 MPa, and compression stress within 10% strain) and values of tensile parameters (including yield stress, yield load, elastic modulus, yield elongation, elongation within 2 MPa, tensile stress within 1% strain) for comparison. Results: Compression testing: no obvious yield points were observed in the whole process in samples of group B, while obvious yield points were observed in samples of groups A and C. There was no significant difference between groups A and C with respect to yield stress and yield load ( P>0.05); while the yield compressibility in group C was significantly lower than that in group A ( P0.05). Tensile testing: the materials in group B had extremely high tensile strength. The yield stress in groups A and B was significantly higher than that in group C ( P0.05). There was no significant difference with respect to yield load among the 3 groups ( P>0.05); but there was significant difference with respect to yield elongation among the 3 groups ( P0.05). Conclusion: Compared with the Medpor, the polyurethane elastic material is a more ideal artificial auricular scaffold material.

Clinical applications of ear reconstruction with Medpor / 中南大学学报(医学版)

Objective:To discuss clinical practice,efficacy and surgical techniques for ear reconstruction with Medpor.Methods:Medpor ear reconstructions were used to treat 19 microtia in 17 patients (including 2 bilateral patients) in Xiangya Hospital,Central South University from January 2011 to December 2015.Reconstructions included 2 patients with one-stage ear reconstruction with temporoparietal fascial flap,2 patients with one-stage operation implanting Medpor directly into skin pocket,and 13 patients with two-stage ear reconstruction.Results:After 1-3 years of follow-up,16 microtia in 14 patients gained ideal appearance.Scaffold exposure occurred in 3 unilateral cases,among which one patient who underwent debridement,removal of superficial exposed scaffold and transposition of local flap to salvage exposure was not significantly influenced,and the other 2 patients' scaffolds were still exposed after repairs and finally removed.One stent was removed at the patient's urging because it induced an exacerbation of periarthritis of the right shoulder.Conclusion:Medpor ear scaffold has advantages,such as easy assembly,good immunologic compatibility,fast vascular ingrowth,simple operation,short operative time and ideal appearance of the reconstructed ear.Medpor is an alternative for microtia repair when patients are unwilling to use autologous rib cartilage or costal cartilages are calcified.However,the relatively high incidence of scaffold exposure reminds us that the indications of Medpor should be taken seriously,and measures to avoid skin necrosis and scaffold exposure should be implemented.Long-term follow-up efficacy needs to be proved.

Study of removing the Medpor and transplanting an expander at the same operative stage to repair the Medpor exposure after ear reconstruction / 中华整形外科杂志

Objective@#To explore the clinical effect by using expander implantation immediately to repair the Medpor exposure after ear reconstruction.@*Methods@#From May 2013 to February 2017, 5 patients were treated with ear reconstructive surgery by Medpor implantation. The previous methods contained not only the auricular posterior fascia flap but also skin grafting. Exposed parts were the upper part of the helix and the wounds were dry without purulent secretions. Bacterial culture did not show bacterial growth. Surgical procedure was to remove the Medpor implant and implant a 50 ml kidney expander. When the wound was healed, we started to inject normal saline into the expander. About 3 months later the total volume of normal saline in the expanders were 80-100 ml.Then we could begin the second operation. We removed the expander and harvested the right side of the 7th and 8th rib cartilage, which were carved into the ear cartilage framework and transplanted into the expansion area. The drainage tube, negative pressure and cotton pad appropriate pressure bandage were needed. 6 days later we removed drainage tube.10 days later we removed the suture.@*Results@#The reconstructed external ear shape in five cases were good. No infection occurred. With 6-20 months of follow-up using telephone and WeChat, no obvious deformation of the shape or cartilage exposure occurred. The five patients did not come back to do the third stage operation for financial considerations. They all left their hometown to work out to reduce economic pressure.@*Conclusions@#In the case of ear reconstruction for Medpor prosthesis exposure, if the wounds were not infected, removing the Medpor and transplanting an expander at the same operative stage can achieve a good therapeutic effect.

Maxillofacial reconstruction with Medpor porous polyethylene implant: a case series study

OBJECTIVES: The role of alloplastic materials in maxillofacial reconstruction is still controversial. Determining the utility of porous, high-density, polyethylene implants as a highly stable and flexible, porous alloplast, with properties such as rapid vascularization and tissue ingrowth, is crucial in cases of maxillofacial deformities and aesthetic surgery. MATERIALS AND METHODS: Thirty high-density porous polyethylene implants were implanted in 16 patients that had been referred to a private office over a three-year period. These implants were used for correcting congenital deformities, posttraumatic defects and improving the aesthetic in nasal, paranasal, malar, chin, mandibular angle, body and orbital areas. RESULTS: The outcomes of the cases in this study showed good aesthetic and functional results. The majority of patients had no signs of discomfort, rejection or exposure. Two implants suffered complications: a complicated malar implant was managed by antibiotic therapy, and an infected mandibular angle implant was removed despite antibiotic therapy. CONCLUSION: Based on the results, the Medpor implant seems to be an excellent biomaterial for correcting various facial deformities. Advantages include its versatility and relatively ideal pore size that allows for excellent soft tissue ingrowth and coverage. It is strong, flexible and easy to shape.

Delayed Orbital Hemorrhage around Alloplastic Implants after Blowout Fracture Reduction

Alloplastic implants have been used to repair orbital wall fractures in most cases. Orbital hemorrhage is a rare complication of these implants and has been reported rarely in Korea. The purpose of this article is to report a late complication case focusing on their etiology and management. A 20-year-old male patient underwent open reduction with Medpor (porous polyethylene) insertion for bilateral orbital floor fractures. The initial symptom occurred with proptosis in the right side as well as vertical dystopia, which had started 4 days earlier, 8 months after surgery. Any trauma history after the surgery was not present. We performed an exploration and removal of hematoma with Medpor titanium meshed alloplastic implant. A case of delayed orbital hematoma following alloplastic implant insertion was identified. It occurred within the pseudocapsule of the implant. One week after surgery, overall symptoms improved successfully, and no complications were reported during the 11-month follow-up period. Although rare, orbital hemorrhage is a potential complication of alloplastic orbital floor implants, which may present many years after surgery. As in the case presented, delayed hematoma should be included in the differential diagnosis of late proptosis or orbital dystopia.

Medpor en Hipoplasia Nasal: agenesia de tercios superior, medio y septum nasal / Medpor in nasal hypoplasia: Upper, middle third and nasal septum agenesis

El desarrollo de las estructuras faciales está a cargo de células derivadas de la cresta neural, alteraciones en la migración o proliferación celular pueden desencadenar malformaciones nasales. Los defectos nasales son tan antiguos como la humanidad, sin embargo, descripciones anatómicas detalladas de estas malformaciones nasales congénitas y sus reconstrucciones son escasas. La hipoplasia nasal puede definirse como un trastorno en el desarrollo de los huesos y cartílagos nasales, y debe ser diferenciada de la arrinia, la cual consiste en la ausencia de nariz y fosas nasales. Los tejidos autologos son los injertos preferidos para la reconstrucción nasal. El tabique nasal, el cartílago auricular, la calota y el cartílago costal son los más usados; pero, estos recursos son limitados, impredecibles y causan algún grado de morbilidad en el sitio donante. Se presenta el primer caso de ausencia de huesos nasales, septum nasal y cartílagos laterales superiores con cartílagos alares intactos. Adicionalmente se presentan los detalles de la reconstrucción usando aloplasticos de alta densidad (polietileno, MEDPOR)...

Neural crest cells are responsible for the development of facial structures, migration failure, decreased proliferation or increased apoptosis may cause nasal anomalies. Nasal defects have existed as long as man; but, detailed anatomic descriptions of congenital nasal defects are rare, the ones including surgical reconstruction are even fewer. Nasal hypoplasia could be defined as nasal bone and cartilage maldevelopment and must be differentiated from congenital arhinia consisting of an absence of nasal structures and passages. Autogenous tissues have been the gold standard graft material for nasal reconstruction; septum, ear, rib and calvarium are preferred. Here, we report the first case of a non-syndromic absence of nasal bones, upper lateral cartilages and septum, with intact lower lateral cartilages and its reconstruction using high-density polyethylene (Medpor)...
