"Management of recurrent temporomandibular dislocation using orthodontic traction screws."

Temporomandibular joint dislocation is defined as the loss of joint congruency between the mandibular condyle and the glenoid fossa of the temporal bone. Multiple therapeutic options have been proposed for the treatment of recurrent TMJ dislocation. The aim of this paper is to present two recently treated cases with a modification of Wolford's technique, replacing the Mitek anchors with orthodontic screws. Case series: The first case concerns a 36 year-old women with recurrent temporomandibular dislocation, and the second one a 26 year-old patient with the same diagnosis. In both cases, one 8mm orthodontic screw was placed in the lateral pole of mandibular condyle, sutured with PremiCron® 2/0 to a hole made in the root of each zygomatic arch. At twelve-month follow-up (first patient) and at six-month follow-up (second patient), patients had not presented new episodes of mandibular dislocation and mouth opening range remained stable. This technique can be considered as an alternative to Wolford's technique in treating recurrent temporomandibular dislocation when conservative management fails.

A Novel Flap for Dynamic Reanimation of Facial Paralysis: Microvascular Sternohyoid Muscle Free Flap.

The main objectives of facial reanimation procedures include restoring facial symmetry at resting state and regaining facial mobility. Static procedures usually provide unsatisfactory results, especially in younger patients. For this reason, over the years, several different surgical alternatives based on autologous, locoregional, or muscle free flaps have been proposed. The gracilis muscle is the gold standard technique for dynamic reanimation of long-standing facial paralysis. The excessive muscle bulk and the differences regarding the type of predominant muscle fiber were compared with the zygomaticus major force reconstructive surgeons to search for alternatives to the gracilis as a potential free flap for reanimation. One of them is the sternohyoid muscle flap. We report a patient with long-standing facial paralysis who underwent a dynamic facial reanimation by using a sternohyoid muscle free flap, thus proposing the procedure as an alternative to the conventional gracilis muscle flap.

Zygomatic intraosseous haemangioma: reconstruction with an alloplastic prosthesis based on a 3-D model.

Intraosseous haemangioma are rare, benign tumours, and only rarely do they involve the facial bones. We present a singular case of zygomatic intraosseous haemangioma treated surgically and reconstructed with a methyl-methacrylate alloplastic prosthesis designed from a computed tomography (CT)-based 3D model. This is the first case described in the literature of a zygomatic reconstruction with a predesigned prosthesis. After 1 year of follow-up, aesthetical results are good, and the patient presents correct functional rehabilitation.

Tratamiento del maxilar posterior atrófico mediante la técnica de elevación de seno maxilar y colocación de implantes dentales / Treatment of the atrophic posterior maxilla using the sinus grafting technique and the placement of dental implants

Objetivo: Presentar el tratamiento de los pacientes con maxilar posterior atrófico mediante la técnica de elevación sinusal. Material y método: Estudio prospectivo sobre una serie de 78 intervenciones de elevación de seno realizadas durante 5 años en 60 pacientes. La técnica de elevación unida a la colocación simultánea de los implantes se realizó en los casos con más de 5 mm de altura ósea residual, mientras que en los de mayor atrofia, los implantes se insertaron en una segunda fase, tras la consolidación del injerto realizado en el suelo del seno. Resultados: 50 elevaciones se realizaron en una sola fase con la colocación simultánea de 89 implantes, de los que se perdieron ocho. 28 casos fueron tratados en dos fases realizándose injerto autólogo de cresta ilíaca en 27. Hasta el momento se han colocado 38 implantes en 18 de estos casos, habiendo fracasado solo uno. La complicación intraoperatoria más frecuente fue la rotura de la membrana sinusal, que ocurrió en 15 casos (19 por ciento), la mayoría leve. Conclusiones: La técnica de elevación de seno maxilar tiene resultados muy satisfactorios en el tratamiento del maxilar posterior atrófico, especialmente con el uso de injerto de hueso autógeno iliaco y colocación de los implantes en un segundo tiempo.
