OBJECTIVES To evaluate the influence of the type of osteotomy in the inferior aspect of the mandible on the mechanical performance. MATERIALS AND METHODS The study was performed on 20 polyurethane hemimandibles. A sagittal split ramus osteotomy (SSRO) was designed in 10 hemimandibles (group 1) with a vertical osteotomy in the buccal side (second molar level) and final osteotomy was performed ...

i ntroduction:   the  trigeminocardiac  reflex  (tcr)  refers  to  the  sudden development of bradycardia as well as asystole along with arterial hypotension associated with any manipulation of sensory branches of the trigeminal nerve. clinically, the tcr has been reported to occur during craniofacial surgery. it is crucial to learn about this sudden physiological response during maxillofacial ...

Distal femoral fractures thigh up from 4 to 9% of all fractures of the femur. There is a direct relationship between the mechanism of receipt of the lesion and the age, sex and the type of fracture. Caused mainly by high-traumatic effects and lead to a high degree of disability. For these reasons, injuries in this anatomical area are of great social importance. The goal of the distal femur frac...

INTRODUCTION Failed treatment for avulsion fracture of the tibial attachment of the anterior cruciate ligament (ACL) leads to anterior knee instability when the avulsion fragment is displaced. Anatomical reduction and fixation of the fragment are widely recommended for type III and IV displaced fracture. Although several surgical techniques for arthroscopic reduction and internal fixation (ARIF...

Two new species of the subfamily Cypricercinae McKenzie, 1971 are described from Western part Thailand: Pseudostrandesia ratchaburiensis sp. nov. and Strandesia prachuapensis is mainly characterized by a flange on antero-ventral left valve (LV), markedly large ? seta mandibular (Md) palp, serrated bristles third endite maxillula (Mx1), slender caudal ramus (CR) with long claw Ga (length ca half...

PURPOSE Two common treatments of temporomandibular joint ankylosis are gap arthroplasty and ankylosis resection and reconstruction of the ramus-condyle unit with a costochondral graft. The purpose of the present study was to answer the following clinical question: "Among patients with temporomandibular joint ankylosis, do those patients who undergo gap arthroplasty, compared with those who unde...

PURPOSE The purposes of the present study were: to compare the resonance frequency analysis (RFA) values of implant placed in either ramus or calvaria block grafts; and to determine if implant diameter influences RFA implant stability quotient (ISQ) value. MATERIAL AND METHODS This was a retrospective study that included 16 consecutives healthy patients treated with autogenous onlay block gra...

BACKGROUND The placement of endosseous implants in edentulous areas is frequently limited by inadequate bone volume of the residual ridge. Local bone grafts from the mandible are a convenient source of autogenous bone for alveolar reconstruction prior to implant placement. PURPOSE The aim of the present study was to document and compare the morbidity and the frequency of complications occurri...

Considerable variation exists in mandibular ramus form among primates, particularly great apes and humans. Recent analyses of adult ramal morphology have suggested that features on the ramus, especially the coronoid process and sigmoid notch, can be treated as phylogenetic characters that can be used to reconstruct relationships among great ape and fossil hominin taxa. Others have contended tha...

Osteochondritis dessicans of the femoral head is an uncommon problem. Limited literature reports the incidence of osteochondritis dessicans and its treatment. The surgical technique used and outcomes for a 40-year-old man with symptomatic femoral head osteochonditis dissecans who was treated 11 years previously with retrograde drilling and hip arthroscopy are discussed.Despite temporary symptom...
