BACKGROUND To analyze the face vascularization pattern using B-mode and Doppler ultrasonography, and also propose an arterial vessel mapping. MATERIAL AND METHODS The investigation was performed on 20 ultrasonography exams of facial vessels through linear and endocavitary transducers. We analyzed and determined the average values for diameters, peak systolic velocity and resistive index of th...

The current standard of managing facial bone fractures is the use of rigid internal fixation. This method provides good stabilization and repair for mid-face fractures such as the zygomatico-orbital fracture. Nowadays, for the young and old, patients want not only rapid bone healing, but also good facial aesthetics after surgical treatment following maxillofacial trauma. Therefore, osteosynthes...

OBJECTIVE To objectively evaluate the effects of maxillary lesions on the infraorbital nerve (ION). METHODS We investigated the latencies (R1, R2) of the blink reflex, stimulating the infraorbital foramen electrically (18 mA, 0.2 millisecond). Twenty-two patients with unilateral maxillary lesions were enrolled. RESULTS Ten patients showed delayed or absent R1 on the lesion side. Four of 20 ...

OBJECTIVE: Determining/ Identifying the localization of infraorbital foramen (IOF) and its relationship with surrounding structures have great importance for many clinical disciplines. It is suggested that supraorbital foramen/notch (SOF/SON) can be used as a landmark to estimate location IOF. In this study, using morphometric relationships IOF SON other neighboring anatomical structures, we ai...

Aspidoras mephisto n. sp. is described from the Anésio-Russão cave system, upper Tocantins River basin, Goiás, Brazil. The species can be readily distinguished from its congeners by troglomorphic features and also by presenting the following combination of features: infraorbital 1 generally with well-developed ventral laminar; or moderately developed; poorly-developed serrations on posterior ma...

The cephalic lateral line canal systems were compared among 12 species of the cyprinid tribe Opsariichthyini. All species were characterized by the separation of the supraorbital canal from both the infraorbital and the temporal canals, and the left side of the supratemporal canal from the right side of the canal. In species of Candidia, Opsariichthys, Parazacco, and Zacco, and Nipponocypris si...

Six patients with blowout fractures of the orbital floor, not associated with infraorbital rim fractures, are presented. Diplopia, infraorbital anesthesia and enophthalmos following blunt trauma to the eye should alert the examiner to the possibility of a blowout fracture with incarceration of extraocular tissues. Early roentgenographic examinations are often difficult to evaluate because of pe...

PATIENT 1 65 y/o M with history of previous resection of cutaneous SCCa of right cheek. Presented to clinic in 2008 with two year history of progressive right facial weakness, diplopia and pain in a trigeminal distribution. Had already undergone craniotomy with nondiagnostic biopsy because of concerns regarding cavernous sinus. On exam had right ophthalmoplegia and facial paralysis; no obvious ...
