Orthognathic surgery: antibiotic prophylaxis reduced surgical site infection


This new Cochrane review identified 11 RCTs and suggests that for those undergoing orthognathic surgery, long term antibiotic prophylaxis decreased the risk of surgical site infection compared with short-term regimens.

Some evidence to suggest that bioresorbable plates may be effective for orthognathic surgery


Internal fixation for orthognathic surgery is commonly performed using titanium plates and screws although in recent years there has been an increase in the use of bioresorbable fixation systems.  However there are concerns about the stability of fixation. The aim of this review was to include all publicly available literature on the skeletal stability of [read the full story…]

Review shows that tranexamic acid reduced blood loss in orthognathic surgery


Significant blood loss can occur during orthognathic surgery and there are risks associated with blood transfusion so minimizing blood loss during surgery is important.  A large number of trials and reviews have shown that the antifibrinolytic agent tranexamic acid ( a synthetic amino acid lysine analog )  can effectively reduce bleeding in a number of [read the full story…]

What motivates patients to seek orthognathic treatment?


Satisfaction with orthognathic treatment for dentofacial deformity is generally high. However, an important minority of patients are dissatisfied with the outcome, often despite technically good results.  The aims of this study were to qualitatively explore and analyse the full range of impacts of dentofacial deformity, and to understand patients’ motivations for seeking orthognathic treatment. The [read the full story…]

Surgical advancement of the maxilla in cleft lip and palate patients appears to show a moderate relapse rate in the horizontal plane and a high relapse rate in the vertical plane


More than 25% of patients with cleft lip and palate (CLP) develop hyperplasia of the maxilla that requires surgical correction. This surgery is usual occurs in the final phase of their CLP treatment and is typically a Le Fort I osteotomy. The aim of this review was to assess the long term stability of this [read the full story…]

Insufficient trial evidence that any surgical treatment for prominent lower front teeth is better or worse than another

Logo of The Cochrane Collaboration

Prominent  lower front teeth can  be associated with a large or prominent lower jaw and/or a small or retrusive upper jaw . The reasons why this occurs are not well understood.  Treatments to correct this range from orthodontic to surgical.  The aim of this Cochrane  review was to evaluate different treatments of Angle Class III [read the full story…]

Tranexamic acid is effective in controlling blood loss in orthognathic surgery


Conservation of blood is important in all forms of surgery and approximately 30% of patietns undergoing bimaxillary osteotomies require a transfusion. The aim of this trial was to assess the effect of tranexamic acid on blood loss, quality of surgical field and duration of surgery compared to the effect of nitroglycerin induced moderate hypotension alone [read the full story…]

Four types of orthognathic patient; metamorphosizers, pragmatists, shedders, and evolvers


Abnormalities of the jaws and dentition that may constitute a hazard to the maintenance of oral health, and interfere with general well-being of the individual by adversely affecting dentofacial aesthetics, mandibular function, or speech can be defined as dentofacial deformities.  Treatment ( orthognathic ) usually involves combination of orthodontic and surgical treatment.  Satisfaction rates are [read the full story…]

Presence of mandibular third molars during sagittal split osteotomies did not increase complications


The sagittal split osteotomy (SSO) is a common procedure  for the correction of mandibular deformities.  It  was first introduced Schuchardt in 1942  the current technique which has been refined an popularised in subsequent years.   Overall it is a safe procedure the  an important intra-operative complication being  an unfavourable fracture with incidences  varying between  0.7-20% being [read the full story…]
