Transnasal Medial Canthopexy Supported with Autogenous Bone Graft: A New Method for Repair of Traumatic Telecanthus
Introduction:
The medial canthus is an important structure to maintain the shape of the eye and assist in drainage of the lacrimal sac. Traumatic telecanthus is a difficult deformity to treat which involves both esthetic and functional aspects. Transnasal wiring remains the gold standard for repair of the medial canthal tendon (MCT) avulsion; however, it is often complicated by canthal drift, extrusion of wires, and in-fracture of the contralateral orbital bones from pressure by tied wires. In order to overcome traditional transnasal wiring technique pitfalls, this study proposes a transnasal wiring fixation method sup...

Prosthetic Materials Protrusion After Surgical Wall Reconstruction of Temporomandibular Joint Herniation
Abstract:
Herniation of the temporomandibular joint (TMJ) into the external auditory canal (EAC) is rare. The TMJ and EAC are separated by the anterior bony wall of the EAC. Such a defect can be caused by trauma, infection, neoplasm, inflammation, and in rare cases, congenital bony defects. If asymptomatic or mildly symptomatic, supplemental treatment is primarily given, but if the symptoms are severe enough that the patient regularly feels discomfort, surgical procedure is considered. To our knowledge there are no reports about surgery-related complications and recurrence during the postoperative follow-up period for ...

A Potential Complication After Drainage in Odontogenic Descending Necrotizing Mediastinitis: Chyle Leakage
Abstract:
Descending necrotizing mediastinitis is a serious complication of odontogenic infections. Incision and drainage of the maxillofacial infection with mediastinal drainage represent the principal management. However, chyle leakage after drainage in descending necrotizing mediastinitis is rare and has not been reported. Here the authors present a case of a 74-year-old man with chyle leakage after mediastinal drainage, which is successfully treated. (Source: Journal of Craniofacial Surgery)

A Novel Method for Lengthening Iliac Crest Grafts for Mandibular Reconstruction
The objective of this article is to propose a technique for mandibular reconstructions of up to 17 cm, in order to obtain anterior iliac crest grafts smaller than those required, and then lengthen them using corticotomies. This technique has been performed in 5 patients with an indication for reconstruction after partial mandibulectomy due to pathology. Reconstruction of the body of the mandible, including the angle in some cases, was performed using nonvascularized anterior iliac crest grafts. These were elongated using corticotomies and fixed to cover the defect using reconstruction plates and screws (2.4 system). The w...

The Combination of a Buccal Trapezoidal Flap With a Palatal Connective Pedicle Flap for the Closure of Oro-Antral Fistulae
Abstract:
Various surgical techniques have been developed for the closure of oro-antral fistulae (OAF), all of them presenting some limitations. Nineteen consecutive patients with a clinical diagnosis of OAF were enrolled in the present case series study. The technique being tested included the reflection of a buccal trapezoid flap with the OAF at its center. The lesion was then fully exposed and debrided. A palatal pedicle connective graft was split from the overlying mucosa and it was rotated over the lesion and under the buccal flap, thereby double-sealing the fistula. The superficial layer of the palatal flap was l...
