Evaluation of a Fully Digital, In-House Virtual Surgical Planning Workflow for Bimaxillary Orthognathic Surgery.

Background: The advantages of virtual surgical planning (VSP) for orthognathic surgery are clear. Previous studies have evaluated in-house VSP; however, few fully digital, in-house protocols for orthognathic surgery have been studied.

Purpose: The purpose of this study was to evaluate the difference between the virtual surgical plan and actual surgical outcome for orthognathic surgery using a fully digital, in-house VSP workflow.

Prevalence of Surgical Site Infections Following Orthognathic Surgery: A Double-Blind, Randomized Controlled Trial on a 3-Day Versus 1-Day Postoperative Antibiotic Regimen.

Purpose: The purpose of this study was to determine the effect of a 3- versus 1-day antibiotic regimen on the rate of surgical site infection (SSI) in patients undergoing orthognathic surgery at a department of oral and maxillofacial surgery in Halifax, Nova Scotia, Canada.

Materials And Methods: A prospective, randomized controlled trial was conducted. All patients received 1 day of intravenous antibiotics after surgery.

Prevalence of Surgical Site Infections Following Orthognathic Surgery: A Retrospective Cohort Analysis.

Purpose: The purpose of this retrospective study was to determine the prevalence of surgical site infection (SSI) after orthognathic surgery at the Department of Oral and Maxillofacial Surgery of Capital Health and Dalhousie University (Halifax, NS, Canada).

Patients And Methods: A retrospective chart review of all patients undergoing orthognathic surgery from October 2005 through April 2013 was performed. The outcome variable was SSI.

Management of fractures of the nasofrontal complex.

Repair of fractures involving the nasofrontal region remains a mainstay of contemporary oral and maxillofacial surgery. This article discusses the epidemiology of these injuries, anatomy of the area, and management of these fractures with insight into potential complications. These include fractures of the frontal sinus, naso-orbital-ethmoidal region, root of the nose, and associated adjacent structures.

Thin serial step sectioning of sentinel lymph node biopsy specimen may not be necessary to accurately stage the neck in oral squamous cell carcinoma.

Purpose: The purpose of this study was to assess the predictability of sentinel lymph node biopsy (SNB) for oral squamous cell carcinoma (OSCC) when pathologic processing is performed without serial step sectioning.

Materials And Methods: We prospectively enrolled 36 patients with T1 or T2 cN0 OSCC into this institutional review board-approved prospective cohort study, and they underwent gamma probe-guided SNB in addition to selective neck dissection. The rate of patients with negative SNB results whose neck dissection was also negative for metastasis (negative predictive value) was the primary endpoint.

The presence of mandibular third molars during sagittal split osteotomies does not increase the risk of complications.

Purpose: The purpose of this study was to investigate prospectively the effects of the presence or absence of third molars during sagittal split osteotomies (SSOs) on the frequency of unfavorable fractures, degree of entrapment and manipulation of the inferior alveolar nerve (IAN), and procedural time.

Materials And Methods: The investigators designed and implemented a prospective cohort study and enrolled a sample composed of patients who underwent SSOs to correct mandibular deformities. The primary predictor variable was the status of the mandibular third molar at the time of SSO, and it was divided into 2 levels, present at the time of SSO (group I) or absent at the time of SSO (group II).

Basosquamous carcinoma involving the anterior skull base: a neglected tumor treated using intraoperative navigation as a guide to achieve safe resection margins.

Basosquamous carcinoma (BSC) or metatypical carcinoma is a rare and controversial form of basal cell carcinoma (BCC) that was first described by MacCormac in 1910. Numerous theories have been described in the literature regarding its origin but it is generally accepted as a variant of BCC that differentiates into squamous cell carcinoma (SCC). At present, it has an unsatisfactorily established phenotype but is considered to behave more like an SCC than a BCC.

Facial appearance following surgical treatment for obstructive sleep apnea syndrome.

Obstructive sleep apnea syndrome (OSAS) is a serious medical condition that is associated with numerous negative health side effects. The general dentist plays an invaluable role in identifying patients with this condition. Certain OSAS patients receive significant medical and social benefits from orthognathic surgery to advance the maxilla, mandible, and chin.
