OBJECTIVE: As most orthognathic surgeries focus on the lower face, the aim of this study was to transfer previously developed two-dimensional cephalometry-which is useful for surgeons in the orthognathic surgery of the lower face-to three-dimensional (3D) cephalometry by using cone-beam computed tomography (CBCT). We selected the quadrilateral lower face analysis developed by the surgeon Di Paolo, who focused only for the lower face and mentioned that data in millimeters are more easy to use than angles for surgeons...

INTRODUCTION: Although some studies addressed the differences between subciliary and transconjunctival approaches, no previous prospective comparative study on displaced zygomaticomaxillary complex (ZMC) fracture that repaired by three-point internal fixation using also upper gingivolabial incision and upper eye lid incision. So, the effect of these incisions on the comparison was not investigated. PURPOSE: The purpose of this study was to compare transconjunctival and subciliary approaches for open reduction and internal rigid fixation (OR/IF) of ZMC fractures...

Odontogenic orbital abscess is a rare but well-documented complication of sinusitis and infections spreading from dental apical lesion. We report a case of orbital abscess with periorbital cellulitis, in a 35-year-old man with positive recent dental history of a periapical dental infection arising from the second upper left premolar spread into maxillary sinus. The patient has shown facial edema, ocular pain, ophthalmoplegia, proptosis, and initial visual symptoms. A surgical intervention to drain the abscess and a revision of the dental lesion and maxillary sinus were required...

PURPOSE: We will aim to develop implants made of a Ni-Ti shape memory alloy which can be applied for the treatment of midface fractures, such as isolated orbital floor fractures. These can then be implanted in a compressed form and unfold automatically in the body. With the help of newly developed application instruments, the implants can be applied along transnasal and transantral approaches into the maxillary sinus. Our objective is to evaluate the operation process and the functionality of these implants, already in a pre-investigation by an experienced surgeon on a phantom...

Temporomandibular joint arthrocentesis and arthroscopy have recently exceeded open surgeries for disorders that failed to respond to conservative treatment. The efficacy of arthrocentesis in reestablishing normal mouth opening and reducing pain and dysfunctions is now commonly accepted, but in contrast to arthroscopy, there are no large series studies on arthrocentesis complications. We report the major complication occurred in our experience: a case of a patient that complained of a violent vertigo, without hearing disorders, following the procedure...

BACKGROUND: Producing youthful facial appearance by face-lifting often comes along with an undesired loss of patient's individual phenotype. This may result from insufficient preservation of retaining ligaments, the "guardians of facial identify," and from severance of the intersegmental connections of the superficial musculo-aponeurotic system (SMAS), which tether, structure, and compartmentalize facial soft tissue into defined, relevant anatomical zones. METHODS: The technique reported here preserves most retaining ligaments...

INTRODUCTION: TMJ arthrocentesis involves lavage of the upper joint space which forces the disc apart from the fossa and washes away the inflammatory components of the joint. To increase the joint space during arthrocentesis, the patient is usually asked to open the mouth and deviate it to the opposite side so as to distract the condyle from the glenoid fossa thereby increasing joint space. METHOD: The authors describe a simple and rapid technique of preparing a custom-made mouth prop to hold the mandible in eccentric position during arthrocentesis...

PURPOSE: The goal of orbital reconstruction is to restore anatomy, volume, and function. In extensive orbital floor defects, the visualization of the posterior area is limited through inferior eyelid incisions. The use of endoscope may improve the treatment; however, it is a high-sensitivity technique. The aim of this case series is to describe the combination of inferior eyelid incision with transantral endoscopy for treatment of extensive orbital floor defects. METHODS: Three patients were submitted to orbital reconstruction, and the postoperative CT scans were evaluated to analyze the orbital volume and anteroposterior globe position...

Spontaneous herniation of temporomandibular joint into the external auditory canal through the foramen of Huschke is a very rare condition. We describe a case of spontaneous temporomandibular joint herniation in a 35-year-old male, who presented with otorrhea and aural fullness. The herniation was repaired using collagen mesh. A literature review of all the previous reported cases of spontaneous temporomandibular joint was done to study the presenting clinical features and the method of surgical repair.
