BACKGROUND: Trigemino-cardiac reflex is a physiologic response of the body to pressure effects in the region of distribution of the trigeminal nerve. Oral and maxillofacial surgical procedures can induce the development of this reflex, which leads to significant changes in the heart rate and sinus rhythms. This study intends to evaluate the effects of this reflex in patients with facial fractures and its subsequent management. PATIENTS AND METHODS: A total of thirty-seven patients with facial fractures who reported to the Department of Oral and Maxillofacial Surgery at Basaveswar Teaching and General Hospital, Gulbarga during a period from July 2015-March 2016 were considered for the study...

BACKGROUND/AIM: There is no data available to show whether there is a relationship between mandibular fractures and isolated fractures of the posterior and/or latera wals of the maxillary sinus. The aim of this study was to determine whether there is a coincidence between these fracture patterns. METHODS: Four hundred large volume cone beam computed tomography scans (CBCT) of patients with a fracture of the mandible between 2008 and 2013 were analyzed retrospectively...

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...

PURPOSE: This study evaluates the accuracy of a statistical shape model (SSM) for virtual fracture reconstruction of the lateral midface. MATERIALS AND METHODS: A uniform bony defect of the right zygoma was created. A virtual reconstruction was performed by using the standard procedure of mirroring the unaffected to the affected side (Group I) and by using the statistical model based on 178 pathologically unaffected CT scans (Group II). The accuracy of the statistical shape model was evaluated in comparison to the present mirroring protocol...

OBJECTIVE: With orbital floor fracture incidence rates increasing year by year, many patients require surgical treatment to improve diplopia, limitation of extraocular muscle movement (EOM), enophthalmos, and midface appearance. With the use of high-density polyethylene, titanium screws, titanium plate, and titanium mesh to repair an orbital floor fracture, enophthalmos and midfacial deformity correction procedures have made great progress. However, attenuating diplopia and the limitation of EOM are still difficult problems to prevent...

CONTEXT: Slotplates were specifically designed to meet the special requirements of corrective surgeries of the facial skeleton. This design enables small readjustments of bone fragments in the midface and chin area during surgery without complete removal of plates and screws. OBJECTIVE, DESIGN, AND SETTING: The aim of this study was to compare morbidity rates of slotplates versus meshplates after Le Fort I osteotomy, genioplasty and/or zygoma 'sandwich' osteotomy performed in a tertiary care centre...

#9
Ahmed Gaber Hassanein, Ahmed M A Abdel Mabood
PURPOSE: During surgery for major maxillofacial fractures, orotracheal intubation can interfere with some surgical procedures and nasal intubation can be contraindicated or impossible. That is why tracheotomy is presented as a solution, although it carries a relatively high incidence of complications. In this study, the use of submandibular tracheal intubation is basically evaluated as an alternative to tracheotomy in such circumstances. MATERIALS AND METHODS: This prospective study was performed in patients undergoing surgery for major maxillofacial fractures in which oral intubation and/or nasal intubation have been unsuitable, impossible, or contraindicated...

Midface fractures usually affect the orbital cavity. This trauma may result in severe and rare consequences such as retrobulbar hemorrhage. This condition requires immediate diagnosis and early intervention to avoid blindness. The treatment usually requires evaluation of an oral and maxillofacial surgeon. This patient report aims to describe a facial trauma resulting in blindness after 4 days. An 83-year-old woman fell and hit her face on the floor. The initial evaluation only found a contusion on her left orbit, and an ophthalmologic examination was not made...

This study evaluated the bite force, electromyographic activity, and mandibular mobility in patients undergoing surgery for facial fracture treatment that required a coronal approach. Ten men were divided into two groups: group I, coronal approach with pre-auricular extension (n=4, average age 34.5 years); group II, coronal approach (n=6, average age 24.8 years). The maximum bite force was measured using a dynamometer and mandibular mobility using a calliper. The electromyographic activity of the right masseter (RM), left masseter (LM), right temporal (RT), and left temporal (LT) muscles was evaluated using a Myosystem-Br1 apparatus...

PURPOSE OF REVIEW: Management of midface trauma is complex and challenging and requires a clear understanding of the facial buttress system, subunit anatomy and inter-relationships. Too often clinicians attempt surgical repair without adequate knowledge of the common complications associated with poor reduction and improper sequencing of fracture repair. This review outlines a working approach to the identification and management of such injuries, and the definitive management of common injury patterns...

From 2002 to 2006, more than 117,000 facial fractures were recorded in the U.S. National Trauma Database. These fractures are commonly treated with open reduction and internal fixation. While in place, the hardware facilitates successful bony union. However, when postoperative complications occur, the plates may require removal before bony union. Indications for salvage versus removal of the maxillofacial hardware are not well defined. A literature review was performed to identify instances when hardware may be salvaged...

The aim of this study is to see whether the nasojugal groove and wrinkles can be improved following a skin-muscle flap elevation through a subciliary approach to the orbital rim.Fifty-seven patients having fractures of the orbital floor, wall, or orbital rim were included. A subciliary incision was made 3 to 5 mm below the cilia. A skin-muscle flap was elevated and a 5-mm width of the periosteum of the anterior surface of the maxilla was exposed. Thereafter, the origin of the orbicularis oculi muscle was released from the underlying bony origin...
