Bone reconstruction in craniofacial surgery is a challenge for surgeons, who most commonly adopt the autogenous bone grafting and alloplastic implants in such procedures. Among the alloplastic materials, the high-density porous polyethylene is highlighted-Medpor (Medpor, Porex Surgical Inc, Newman, GA), considered to be pure polyethylene, with only 1 manufacturing process and standard pore size. The purpose of the current study has been to present through a review of literature and the types of complications derived from the use of Medpor in craniomaxillofacial bone surgery. A specific and sensitive database was initially created via PubMed, focusing on studies published in English peer-reviewed journals between 2004 and 2014, including case reports, experimental studies in humans, and prospective and retrospective studies. Forty articles were found at PubMed database. After analyzing their abstracts, 19 were selected, totaling 1453 patients and 121 complications, being the most commonly reported diplopia with 56 patients and infection with 6 patients. Most of the complications reported in the articles used for the development of the current review are not directly related to the use of the Medpor implant. The only complications directly related to the use of this biomaterial were cases of infection.

Odontogenic myxomas (OMs) are nonencapsulated rare benign tumors that can occur in gnathic bones. They are locally invasive and have a high recurrence rate. Radiologically, OMs show a multilocular (in the majority of cases) or unilocular radiolucency, with either distinct or poorly defined margins. Histopathologically, OMs are characterized by spindle-, wedge-, or stellate-shaped cells loosely arranged in an abundant mucoid background. Myxomas are mainly asymptomatic. Radical surgery, excision, and enucleation followed by curettage of the surrounding bony tissue have all been advocated as treatment options. This study presents a successful case of conservative treatment of OMs with a 5-year follow-up.

Fractures of atrophic mandibles are present on the day by day of buccomaxillofacial surgeons. Mandible atrophy occurs due to tooth loss, which over time induces bone resorption leading to a fragile and susceptible to fracture structure. This paper reports the case of a patient victim of face trauma resulting in atrophic mandible fracture with treatment failure through the use of shared load miniplate. Therefore, a new treatment was performed with miniplate of system 2.4 along with bone graft. After 6 months, the patient was rehabilitated with implant-supported prosthesis installation. It is concluded that for successful treatment of atrophic mandible fractures, the use of rigid plates is necessary, allowing an excellent rehabilitation of the stomatognathic system.
