Implant-oriented navigation in orbital reconstruction. Part 1: technique and accuracy study
Intraoperative navigation is frequently used to assess the position of the implant in orbital reconstruction. Interpretation of the feedback from the navigation system to a three-dimensional position of the implant needs to be done by the surgeon, and feedback is only gathered after the implant has been positioned. An implant-oriented navigation approach is proposed, with real-time intuitive feedback during insertion. A technical framework was set up for implant-oriented navigation, with requirements for planning, implant tracking, and feedback. (Source: International Journal of Oral and Maxillofacial Surgery)

The trajectory of positive psychological change in a head and neck cancer population
A stressful event may be sufficient to challenge a strongly held set of assumptions about the world and the self. In some people this may lead to post-traumatic stress disorder (PTSD) and in others to positive psychological change (PPC), whereby a person ’s reactions to the challenge are beneficial. Little research has investigated PPC in people who have had head and neck cancer (HNC). The aim of this study was to identify demographic, clinical, and psychological factors associated with PPC over time. (Source: International Journal of Oral and Maxillofacial Surgery)

SPECT bone scintigraphy for the assessment of condylar growth activity in mandibular asymmetry: is it accurate?
The comparison of serial radiographs and clinical photographs is considered the current accepted standard for the diagnosis of active condylar hyperplasia in patients with facial asymmetry. Single photon emission computed tomography (SPECT) has recently been proposed as an alternative method. SPECT can be interpreted using three reported methods absolute difference in uptake, uptake ratio, and relative uptake. SPECT findings were compared to those from serial comparisons of radiographs and clinical photographs taken at the time of SPECT and a year later; the sensitivities and specificities were determined.

Intrasinusal locking technique: a novel use of the ring block technique at sinus perforations for simultaneous implant placement
Ten patients who underwent sinus lift surgery with simultaneous implant placement using the intrasinusal locking technique were evaluated retrospectively. All patients were scheduled for sinus floor elevation procedures with simultaneous implant placement. Schneiderian membrane perforation occurred during the lifting procedure, and conventional methods failed to repair the perforation. Therefore, an autogenous bone ring was placed at the base of the maxillary sinus and was locked to the alveolar crest with a dental implant.

Oropharyngeal epignathus with partial facial duplication: report of a rare case
Foetal oral teratoma or epignathus is a rare benign condition that originates in the oropharyngeal region. The term ‘teratoma’ refers to a mass composed of poorly organized tissues derived from each of the three germ layers. Epignathus may occur when one twin ceases development during gestation and becomes vestigial to the fully formed dominant twin. The reported incidence of epignathus is approximately 1:35, 000 to 1:200,000 live births. A unique case of partial facial duplication with gross histological and radiological evidence of partial duplication of the facial elements and organs is presented herein. (So...

Secondary surgical management of osteoradionecrosis using three-dimensional isodose curve visualization: a report of three cases
Osteoradionecrosis is defined as bone death secondary to radiotherapy. There is a relationship between the radiation dose received and the occurrence of osteoradionecrosis of the jaws, with the risk increasing above a dose of 60Gy. In cases of class III mandibular osteoradionecrosis, a segmental resection can be indicated. Current practice is to completely remove the affected bone up to the point where the bone looks healthy and is bleeding. Exact resection planning and the use of guided surgery based on imaging of the bone changes have not been reported so far. (Source: International Journal of Oral and Maxillofacial Surgery)

Submucosal injection of dexamethasone and methylprednisolone for the control of postoperative sequelae after third molar surgery: randomized controlled trial
Pain, swelling, and trismus are known sequelae of third molar surgery that can significantly affect the individual ’s quality of life (QOL). These should be minimized to improve QOL. The purpose of this study was to compare the effects of the preoperative submucosal administration of equivalent doses of two commonly used steroids on these postoperative sequelae. A randomized controlled clinical trial was condu cted involving 60 subjects requiring the removal of impacted mandibular third molars. Extraction cases with a similar difficulty index were included.

Two-stage reconstruction of the severely deficient alveolar ridge: bone graft followed by alveolar distraction osteogenesis
Distraction osteogenesis for the augmentation of severe alveolar bone deficiency has gained popularity during the past two decades. In cases where the vertical bone height is not sufficient to create a stable transport segment, performing alveolar distraction osteogenesis (ADO) is not possible. In these severe cases, a two-stage treatment protocol is suggested: onlay bone grafting followed by ADO. An iliac crest onlay bone graft followed by ADO was performed in 13 patients: seven in the mandible and six in the maxilla. (Source: International Journal of Oral and Maxillofacial Surgery)

Previously successful dental implants can fail when patients commence anti-resorptive therapy —a case series
This article reports a type of localized osteonecrosis that can occur in patients who have had successful osseointegrated implants for many years and then commence anti-resorptive therapy. Eleven female patients were identified who had successful implant insertion, but who were placed on anti-resorptive therapy (bisphosphonates or denosumab) several years later and developed osteonecrosis around the implants. In each case, the osteonecrosis occurred only around the implants and not around the patient ’s remaining teeth. (Source: International Journal of Oral and Maxillofacial Surgery)

Cone beam computed tomography-based cephalometric norms for Brazilian adults
This study established cone beam computed tomography (CBCT)-based cephalometric norms for Brazilian adults, including the assessment of sexual dimorphism. An observer performed McNamara ’s cephalometric analysis twice on 60 CBCT datasets acquired from patients with a normal dental occlusion, divided equally into two groups by sex. Welch’s t-test was applied to assess differences between the sexes in hard tissue cephalometric measurements, and Dahlberg’s formula was used to ca lculate measurement error introduced by the observer.

Vertical platysma myocutaneous flap reconstruction for oral defects using three different incision designs: experience with 68 cases
This study evaluated the effects of three different incision designs for the vertical platysma myocutaneous flap (VPMF): apron, MacFee, and T-shaped. This flap was used for the reconstruction of intraoral defects following cancer ablation in selected patients. Sixty-eight cases of VPMF reconstruction were assessed: the apron incision was used in 28, MacFee incision in 22, and T-shaped incision in 18. With regard to postoperative outcomes, there were 26 cases of flap survival and two of partial necrosis with the apron incision; 20 of survival and two of partial necrosis with the MacFee incision; 15 of survival and three of ...

An aggressive and fatal craniofacial group A Streptococcus infection resulting from a minimally displaced orbital floor fracture
While sharp, penetrating trauma is often associated with group A Streptococcus (GAS) infections and subsequent necrotizing fasciitis (NF) and streptococcal toxic shock syndrome (STSS), there are scant reports in the oral and maxillofacial surgery literature regarding blunt, non-penetrating trauma in association with these conditions. With a clinical course that initially appears relatively benign following blunt trauma, NF can progress swiftly through the fascial planes and may quickly become life-threatening if the oral and maxillofacial surgeon fails to recognize some of the critical pathognomonic signs.

Ultrasound versus magnetic resonance imaging of the temporomandibular joint in juvenile idiopathic arthritis: a systematic review
A systematic review of published articles on ultrasound (US) and magnetic resonance imaging (MRI) of the temporomandibular joint (TMJ) in juvenile idiopathic arthritis (JIA) was performed to answer the question “What is the sensitivity and specificity of US as compared to MRI in diagnosing acute and chronic joint changes in patients with JIA?” The most recent evidence was sought in published articles via a search of the PubMed, Ovid, and Embase databases. Article appraisal was performed by two reviewer s. (Source: International Journal of Oral and Maxillofacial Surgery)

Clinical application of autogenous partially demineralized dentin matrix prepared immediately after extraction for alveolar bone regeneration in implant dentistry: a pilot study
In this study, 16 patients underwent dental implant placement using APDDM transplantation. There were no systemic or local complications (including surgical site infection) in any of the cases, and oral rehabilitation using dental implants was successful in all cases for at least 2 years after attachment of the suprastructure.

Hypotensive anaesthesia techniques in orthognathic surgery
We read with interest the article by Lin et al., “Comparison of different hypotensive anaesthesia techniques in orthognathic surgery with regard to intraoperative blood loss, quality of the surgical field, and postoperative nausea and vomiting”.1 It provoked a lot of discussion and an audit of our practice. The low incidence of postoperative n ausea and vomiting (PONV) was particularly notable. In a group of similar cases of similar age and sex ratio, the incidence of PONV requiring intervention in the post anaesthesia care unit (PACU) was 35%, comparable to the sevoflurane group in the study.
