A new technique for medial canthal tendon fixation.

Traumas resulting from naso-orbitoethmoidal fractures and tumor surgery of the medial canthal region may cause orbital dystopia. A variety of techniques with many disadvantages, such as detachment and high cost, has been described for reattachment of medial canthal tendon. We present a new technique, namely, unitransnasal canthoplasty, which is easy to apply, cheap, and reliable. Two nonabsorbable sutures were passed through 2 drill holes to the nasal cavity, taken out from the nasal ostium, and were tied up. Upper and lower eyelids were fixed to the ipsilateral nasal bone.

Biomechanical comparison of a new technique of mandibular angle fractures: biplanar and bicortical superior proximal 3 holes and bicortical inferior plate fixation.

Miniplates have been used for mandibular angle fractures during the past 2 decades. The technique of placing single miniplate at the upper border based on the tension lines of the fracture was proposed by Michelet and Champy. The need for a second miniplate to be applied to the lower mandible has been discussed recently. Biomechanical comparison of biplanar and monoplanar dual-miniplate fixation techniques was investigated by Haug. Our hypothesis is in dual-miniplate fixation; the proximal 3 holes of superior border miniplate could be fixated by bicortical screws. The first 2 are at the proximal bone segment and are not related to the tooth and also superior to the alveolar nerve. Generally, the third molar tooth is extracted because it is at the fracture site. Hence, the proximal third hole could also be fixated by bicortical screws. We define a biplanar dual-miniplate technique in which the lower plate and the proximal 3 holes of the upper plate are fixated by bicortical screws. We have designed a study for biomechanical comparison of our method and popular types of mandibular fixation methods.
