Olfactory and Gustatory Function in Patients With Different Types of Maxillofacial Trauma.

Objectives/hypothesis: To investigate olfactory and gustatory function in patients with maxillofacial trauma and associated fractures.

Study Design: Retrospective cohort study.

Methods: Olfactory and gustatory function was assessed psychophysically in 124 patients who had sustained maxillofacial trauma with an associated fracture.

How accurate is the treatment of midfacial fractures by a specific navigation system integrating "mirroring" computational planning? Beyond mere average difference analysis.

Purpose: To evaluate the accuracy of a specific navigation system integrating "mirroring" computational planning in the treatment of midfacial fractures by comparing planned with actual postoperative 3-dimensional (3D) images.

Patients And Methods: Preoperative planned and postoperative 3D computed tomographic (CT) and cone-beam CT (CBCT) images of 20 patients with midfacial fractures were analyzed. Images were fused using dedicated software (iPlan Cranial 2.

Accuracy of computational soft tissue predictions in orthognathic surgery from three-dimensional photographs 6 months after completion of surgery: a preliminary study of 13 patients.

Background: This study aimed at a preliminary evaluation of the accuracy of computed three-dimensional (3D) predictions in orthognathic surgery by comparing predicted and real postoperative results.

Methods: Pre- and postoperative 3D photographs and time-matching computed tomography (CT) and cone-beam CT scans of the face of 13 patients with dentofacial deformities were analyzed. Three-dimensional photographs were fused with preoperative CT data using dedicated software (3dMDvultus, version 2.

Deep neck space abscesses of dental origin: the impact of Streptococcus group Milleri.

In recent years, there has been rising interest in Streptococcus group Milleri (SM) because high mortality rates have been related to it. In case of deep neck infections (DNI), whatever the origin, mortality rates as high as 26% were reported. But there are no data available for DNI with SM of purely dental origin.

Can systematic computed tomographic scan assessment predict treatment decision in pure orbital floor blowout fractures?

Purpose: To describe and evaluate the reliability and the accuracy of a specific computed tomography-based assessment in predicting treatment decisions for pure orbital floor blowout fractures (BOFs).

Materials And Methods: In this retrospective cohort study, the charts of all patients presenting with isolated BOFs from January 2009 through April 2011 at the University Hospital of Geneva were reviewed. The systematic computed tomographic assessment included the following 3 parameters: 1) ratio of the fractured orbital floor; 2) maximal height of periorbital tissue herniation, and 3) a 4-grade muscular subscore describing the position of the inferior rectus muscle relative to the level of the orbital floor.

A quick guide to positioning the transbuccal set.

Exact positioning of the transbuccal set can be tricky, especially under aggravating circumstances as present scarring or high body mass index. It may result in multiple skin incisions. This article presents a simple and fast guidance technique that can help in the exact positioning of skin incision and transbuccal set.

Image guided surgical navigation integrating "mirroring" computational planning based on intra-operative cone-beam CT imaging: a promising new approach for management of primary bilateral midfacial fractures.

Cosmetic and functional re-establishment following primary or secondary treatment of comminuted and complex midfacial fractures remains a challenge for surgeons. Computer Assisted Surgery (CAS) has revolutionized the conceptualization and approach to these reconstructions and has become a reliable part of the surgical armamentarium. Computer aided design/modeling (CAD/CAM) software that allows "mirroring" planning coupled to navigation systems has dramatically improved surgical strategies in reconstructive surgery of the craniomaxillofacial skeleton, particularly with respect to the prediction of suitable symmetric bone repositioning.

Severe subcutaneous and deep cervicofacial emphysema of unusual etiology.

Subcutaneous and deep cervical emphysema (SCE) in the head and neck are found in a wide spectrum of conditions. Most of them are seen in patients with midfacial trauma or oropharyngeal infections. Subcutaneous and deep cervical emphysema can also be a symptom of life-threatening mediastinitis and/or necrotizing fasciitis, both of which need immediate surgery.

Gustatory dysfunction after mandibular zoster.

Varicella zoster, limited to the mandibular nerve, is rare. Classical symptoms are pain, hypesthesia and vesicular eruption restricted to the third trigeminal segment (V3). Little is known on taste affection after mandibular nerve zoster.

Accuracy and predictability in use of AO three-dimensionally preformed titanium mesh plates for posttraumatic orbital reconstruction: a pilot study.

The aim of this study was to prospectively evaluate the accuracy and predictability of new three-dimensionally preformed AO titanium mesh plates for posttraumatic orbital wall reconstruction.We analyzed the preoperative and postoperative clinical and radiologic data of 10 patients with isolated blow-out orbital fractures. Fracture locations were as follows: floor (N = 7; 70%), medial wall (N = 1; 1%), and floor/medial wall (N = 2; 2%).

Prognostic factors for the malignant triton tumor of the head and neck.

Background: Malignant triton tumors are rare neoplasias consisting of a malignant peripheral nerve sheath tumor with additional rhabdomyoblastic differentiation. These tumors are highly aggressive and prognosis is poor. Our aim is to describe the outcome and to identify potential prognostic factors.

Magnesium sulfate in the management of patients with aneurysmal subarachnoid hemorrhage: a randomized, placebo-controlled, dose-adapted trial.

Background: Recent studies suggest that high-dose MgSO4 therapy is safe and reduces the incidence of DIND and subsequent poor outcome after SAH. We intended to assess the safety and efficacy of high-dose MgSO4 therapy after SAH as means to prevent DIND and to evaluate the impact on clinical outcome.

Methods: This was a prospective, randomized, single-blind, placebo-controlled study.

[Wide-spread subcutaneous emphysema after third molar extraction. Case report].

Two days after wisdom teeth removal an eighteen-year-old man complained of a painful subcutaneous neck emphysema. CT scans showed that the air collections were expanding close to the mediastinum. A conservative intravenous medication with broadspectrum antibiotics was administered and within three days the symptoms resolved completely without any surgical intervention.
