One Point Versus Two Point Fixation of Tripodal Zygomatic Fractures

2020-01-07 08:31:55 | BioPortfolio

Summary

The zygomatic bone defines the anterior and lateral projection of the face and articulates with the frontal, sphenoid,temporal, and maxillary bones. The zygomatic complex is responsible for the protection of the orbital contents and the mid-facial contour. Fracture of the zygomatic complex is one of the most common facial injuries in maxillofacial trauma and predominately appears in young adult males. The etiology of zygomatic complex fractures primarily includes road traffic accidents, violent assaults, falls and sports injuries. The main clinical features of zygomatic complex fractures include diplopia, enophthalmos, subconjunctival ecchymosis, extraocular muscle entrapment, cosmetic deformity with depression of the malar eminence, malocclusion and neurosensory disturbances of the infraorbital nerve. Diagnosis of zygomatic complex fractures is usually clinical with confirmation by computed tomography (CT) scan. Zygomatic complex fractures with no or minimal displacement are often treated without surgical intervention, whereas fractures with functional or esthetic impairments often necessitate surgical intervention. Various surgical approaches and treatment strategies have been proposed to obtain successful treatment outcome, including the Gilles temporal approach, eyebrow, upper eyelid, transconjunctival, infraciliary lower eyelid, and intraoral vestibular approaches. The surgical approach for adequate reduction of zygomatic complex fractures must ensure a good functional and cosmetic result. Surgical reduction of zygomatic fractures by an intraoral surgical approach was first described in1909 by Keen, and several studies have subsequently documented the treatment outcome after open reduction of zygomatic complex fractures by an intraoral surgical approach.

Description

This study is a prospective clinical intervention study where the admitted patients do lab investigation as CBC, coagulation profile ,Kidney function test and Imaging as CT maxillofacial with axial and coronal cuts. Patients will be assigned randomly into either one of the two groups under the study using concealed envelope. Under general anaesthesia with oral or naso-tracheal intubation, open reduction and internal fixation of tripod zygomatic fractures will be done using miniplates and screws at one point (zygomaticomaxillary area) or at two points (zygomaticomaxillary and frontozygomatic areas).

Medical and Biotech [MESH] Definitions

Fractures of the zygoma.

Fractures of the short, constricted portion of the thigh bone between the femur head and the trochanters. It excludes intertrochanteric fractures which are HIP FRACTURES.

Fractures of the FEMUR HEAD; the FEMUR NECK; (FEMORAL NECK FRACTURES); the trochanters; or the inter- or subtrochanteric region. Excludes fractures of the acetabulum and fractures of the femoral shaft below the subtrochanteric region (FEMORAL FRACTURES).

Fractures of the skull which may result from penetrating or nonpenetrating head injuries or rarely BONE DISEASES (see also FRACTURES, SPONTANEOUS). Skull fractures may be classified by location (e.g., SKULL FRACTURE, BASILAR), radiographic appearance (e.g., linear), or based upon cranial integrity (e.g., SKULL FRACTURE, DEPRESSED).

Crumbling or smashing of cancellous BONE by forces acting parallel to the long axis of bone. It is applied particularly to vertebral body fractures (SPINAL FRACTURES). (Blauvelt and Nelson, A Manual of Orthopedic Terminology, 1994, p4)
