The incidence of squamous cell carcinoma (SCC) of the tongue accounts for 90% of all malignancies affecting the oral cavity and oropharynx. The distribution between the anterior and posterior tongue is equal. Nodal metastasis is dependent on various factors including tumour thickness, site, size, differentiation, and perineural and perivascular invasion. There is increasing evidence of a close correlation between tumour thickness and metastasis. A retrospective study covering the 16-year period from 2000 to 2016 was performed...

The goal of rehabilitation after temporomandibular joint (TMJ) surgery is to achieve a normal range of motion. The aim of this study was to compare the impact of a comprehensive and early supervised rehabilitation programme with home-based exercise after TMJ condylar discopexy. Patients diagnosed with disc displacement without reduction were randomized to the study and control groups. After baseline assessments, the same surgical condylar discopexy procedure was applied to both groups. Following surgery, the study group patients underwent a supervised exercise programme conducted by a physiotherapist in the outpatient clinic...

Previous research on the accuracy of flapless implant placement of virtually planned implants in the augmented maxilla revealed unfavourable discrepancies between implant planning and placement. By using the osteosynthesis screws placed during the augmentation procedure, the surgical template could be optimally stabilized. The purpose of this study was to validate this method by evaluating its clinically relevant accuracy. Twelve consecutive fully edentulous patients with extreme resorption of the maxilla were treated with a bone augmentation procedure...

Oral squamous cell carcinoma (OSCC) is a lethal disease, with rising incidence. There were 6767 new OSCC cases and 2056 deaths in the UK in 2011. Cancers are preceded by oral potentially malignant disorders (PMDs), recognizable mucosal diseases harbouring increased SCC risk, offering clinicians a 'therapeutic window' to intervene. Contemporary practice remains unable to predict lesion behaviour or quantify malignant transformation risk. No clear management guidelines exist and it is unclear from the literature whether early diagnosis and intervention prevents cancer...

The purpose of this study was to evaluate the effect of cortical bone perforation on angiogenesis and osteogenesis of the augmented ridge in guided bone regeneration. Eighteen patients who had osseous defects in the mandible were selected. In the test group (n=9), alveolar cortical bone in the area of regeneration was perforated. No decortication was performed in the control group (n=9). Subsequently, defects were augmented by guided bone regeneration using resorbable membrane and bovine bone. After a healing period of 7 months, trephine cores were harvested for histological and histomorphometric analysis of the grafted areas...

Three-dimensional (3D) soft tissue prediction is replacing two-dimensional analysis in planning for orthognathic surgery. The accuracy of different computational models to predict soft tissue changes in 3D, however, is unclear. A retrospective pilot study was implemented to assess the accuracy of Dolphin 3D software in making these predictions. Seven patients who had a single-segment Le Fort I osteotomy and had preoperative (T0) and >6-month postoperative (T1) cone beam computed tomography (CBCT) scans and 3D photographs were included...

The Le Fort I osteotomy is widely used to correct dentofacial deformities. Benign paroxysmal positional vertigo (BPPV) is a common vestibular end organ disorder characterized by short, often recurrent episodes of vertigo. Head trauma is one of the known causes of BPPV. During pterygoid osteotomy, the surgical trauma induced by percussion with the surgical mallet and osteotomes can displace otoliths into the semicircular canal, resulting in BPPV. The aim of this study was to evaluate the potential risk of occurrence of BPPV in individuals undergoing Le Fort I osteotomy...

This pilot study investigated the biomechanical properties of prefabricated, vascularized bioartificial bone grafts, which may provide an alternative bone source for the restoration of segmental osseous defects. Vascularized bioartificial bone grafts comprise an artificial customized scaffold made of beta-tricalcium phosphate. Bone formation along the prefabricated scaffold is induced by autogenous cancellous bone. Vascularization of the bone graft is provided by the host's vascular system. Within 6 months, a mammalian bioreactor (sheep were used in the present study) creates heterotopic vascularized bioartificial bone grafts of a predetermined anatomical shape, which can be harvested for reconstructing osseous defects...

Socket preservation using a combination of porcine xenograft and collagen membrane maintains the vertical and horizontal dimensions of the ridge. The aim of this study was to evaluate the microarchitecture of the grafted area by histological analysis and micro-computed tomography. Patients in the test group (group 1; nine patients) underwent socket preservation, while the sockets in the control group (group 2; eight patients) were allowed to heal without preservation. After a 6-month healing period, bone core biopsy samples were obtained and implants were placed in the augmented sites in the test group (12 biopsy samples) and the non-augmented sockets of the control group (12 biopsy samples)...

While grafting with bone substitutes has been shown to provide greater stability in maxillary advancements, infection remains a concern with any material that is placed in close proximity to the maxillary sinus. The purpose of this study was to evaluate the prevalence of infection in maxillary advancements in which a bone graft substitute (β-tricalcium phosphate; β-TCP) was placed at the time of surgery. This was a retrospective study of all maxillary osteotomies. Patients were divided into two groups: group 1 included maxillary osteotomies in which β-TCP was not used; group 2 included any maxillary osteotomy where β-TCP was used...

Desmoplastic fibromas are rare, benign, but aggressive lesions, affecting predominantly young people, with an affinity for the mandible. Four patients with desmoplastic fibromas of the mandible, seen between 1995 and 2015 with long-term follow-up, were identified. Three were treated by wide mandibular resection and immediate reconstruction with rib grafts, and one was treated with chemotherapy. In the three resected cases, there has been no recurrence and all rib grafts were successfully incorporated. The case treated by chemotherapy has persistence of the tumour, but it is not progressing...

Many authors have studied various different parameters in relation to postoperative anxiety after the extraction of third molars. However, the effect that the acute inflammatory process occurring post extraction could have on these parameters has not been studied. Certain salivary biomarkers, although not specifically inflammatory, may be affected by the acute inflammatory process occurring following the extraction of a retained lower third molar. Three biomarkers were assessed in this study: total protein, immunoglobulin A (IgA), and alpha-amylase...
