Background: Traumatic injuries affecting the veins in the lower extremities have been correlated with both mortality and severe complications. Venous injuries are recognized as a contributing factor to the development of venous thromboembolism, commonly treated through procedures involving either vein ligation or repair. Despite previous efforts, substantial uncertainty remains when it comes to choosing between the execution of ligation versus various reparative techniques.

To prevent this complication, shorten the period of hospitalization and reduce morbidity, routine supplementation of oral vitamin D and calcium has been suggested. This systematic review and meta-analysis aims to critically assess the association between pre-operative calcitriol supplementation and post-operative hypocalcaemia.

Currently, there is no consensus about the ideal type of xenograft for sinus augmentations, and this choice depends on the personal experience of clinicians. This retrospective study aimed to evaluate the effects of three different xenografts used in sinus augmentation simultaneously with implant placement on the survival of the implants and the dimensional changes of the region.

Medical records and orthopantomographic images of 1132 patients and 1478 implants were retrospectively analyzed. Finally, 96 patients (52 females, 44 males) with 111 malpositioned implants were included in the study.

Throughout the history, various synthetic and autogenous materials have been used for dorsal augmentation. In this article, we give an overview of basic concepts of cartilage grafting, review new concepts of dorsal augmentation, and discuss some emerging engineering modalities.
View Article and Find Full Text PDFBiodynamics of mandibular angle fractures has been extensively discussed in the literature in search for the best way to fixate and expedite recovery of trauma patients. Pioneers like Michelet and Champy had the greatest impact on evolving of osteosynthesis in maxillofacial traumatology; they introduced their basic principles frequently used to describe the biomechanics of mandibular fixation. Their concept states when a physiologic load is applied on mandibular teeth a negative tension will be created at superior border and a positive pressure will appear at inferior border.

The goal of this study was to analyze the immediate effect of different steps of open rhinoplasty on NLA and NTP.

Objectives: The authors describe their experience with augmentation of the upper lip using an autologous graft from the temporalis fascia.
The nasal base is an important aspect of the nose with a complex anatomic architecture comprising a combination of cartilages, skin, connective tissues, and ligaments. Recent studies show that all nasal base deformities cannot be corrected by simple excision and suturing techniques. Alar release and medialization would be effective in some of these deformities.
View Article and Find Full Text PDFLateral osteotomy is a controversial step in rhinoplasty, which is usually performed to narrow a wide nose, widen a narrow bony pyramid, straighten a deviated nose, or close an open roof deformity. The osteotomy is performed using several methods, although the internal continuous and external perforator are the main ways to perform the lateral osteotomy. Most other techniques are modifications of these basic methods.

Materials And Methods: This experimental study was performed on simulated human mandibles using computer software. The osteotomy line was applied to the simulated model and experimental loads of 75, 135, and 600 N were exerted on the model in accordance with the vector of occlusal force.
Purpose: The present retrospective study assessed the outcome and effectiveness of the buccal fat pad flap for closure of postoperative midpalatal fistulas and fistulas of the posterior palate in patients previously treated for cleft palate.
Patients And Methods: The charts of 29 patients with residual midpalatal and posterior palatal fistulas treated using buccal fat pad flaps were assessed. Of the 29 patients, 18 were males and 11 were females, aged 2.
Purpose: The aim of this study was to assess the biomechanical stress tolerance of screws used in 9 fixation methods after bilateral sagittal split ramus osteotomy to determine which configuration leads to lesser force load on the cortical bone at fixation points.
Materials And Methods: A 3-dimensional computerized model of a human mandible with posterior teeth was generated. The bilateral sagittal split ramus osteotomy was virtually performed on this model.

Objective: Botulinum toxin type A (BTX-A) has been used to treat migraine and occipital neuralgia. We report preliminary results of an ongoing study that assesses the efficacy of BTX-A on trigeminal neuralgia (TN) patients refractory to medical treatment.
Study Design: We treated 15 patients (8 men and 7 women) between 28 and 67 years of age who were suffering from drug-refractory TN from February 2008 to January 2010.

Aim: This study assessed the causes and incidence of miniplate removal during a 5-year period after Le Fort I osteotomy.
Patients And Methods: One hundred forty-two patients had plates inserted for fixation of the maxilla after Le Fort I osteotomy between 2001 and 2004. The Le Fort I segment was rigidly fixed with four 2-mm titanium miniplates and 16 screws.
Purpose: The purpose of this study was to examine the effectiveness of gap and interpositional arthroplasty with temporalis muscle flap in the treatment of the temporomandibular joint (TMJ) ankylosis.
Materials And Methods: This retrospective study was evaluated on 34 patients who were treated from February 2003 to July 2007. Diagnosis of TMJ ankylosis was based upon the clinical examination and plain radiography and CT scan.
