OBJECTIVE: Endoscopic examination followed by tissue biopsy is the gold standard in the evaluation of lesions of the upper aerodigestive tract. However, it can be difficult to distinguish between healthy mucosa, dysplasia, and invasive carcinoma. Optical coherence tomography (OCT) is a non-invasive technique which acquires high-resolution, cross-sectional images of tissue in vivo. Integrated into a surgical microscope, it allows the intraoperative evaluation of lesions simultaneously with microscopic visualization...

Oral cancer, especially that originates in the maxillary tuberosity, buccal mucosa, and maxillary alveolus, is apt to invade the pterygopalatine fossa, where an intraoral approach is nearly impossible. There are 2 main types of extraoral approach to the pterygopalatine fossa; the anterior approach and the lateral approach. Although the lateral approach has an advantage compared with the anterior approach in terms of cosmetics, after the operation numbness of the lower lip occurs due to the sacrifice of the mental nerve...

INTRODUCTION: The periodontal morphotype is a leading feature to be born in mind during surgical, implant, prosthetic, restorative as well as orthodontic treatment. A fragile morphotype will rapidly trigger severe and worrying clinical repercussions for the patient. MATERIALS AND METHODS: In order to minimize the risks involved, sound knowledge of the different morphotypes and of the techniques for clinically evaluating them is a major requirement. These factors need to be regularly reassessed since morphotypes can vary throughout the course of treatment...

INTRODUCTION: Tooth-arch discrepancy is a disproportion between dental volume and bone base. Extraction therapy can be a solution in case of excessive tooth volume and insufficient basal bone length. Techniques including bone distraction popularized by Ilizarov in the fifties allow the increase of the basal arch length in the maxilla as well as in the mandible. MATERIALS AND METHODS: We will describe the procedure of this dental arch length augmentation since the reflection about the therapeutic plan until the sufficient arch length is obtained and describe the indications of this orthodontic and surgical treatment in case of dental crowding, buccal and labial inclination and functional problems...

Yan Li, Rickard Brånemark
The direct attachment of osseointegrated (OI) prostheses to the skeleton avoids the inherent problems of socket suspension. It also provides physiological weight bearing, improved range of motion in the proximal joint, as well as osseoperceptive sensory feedback, enabling better control of the artificial limbs by amputees. The present article briefly reviews the pioneering efforts on extremity osseointegration surgeries in Sweden and the development of the OPRA (Osseointegrated Prostheses for the Rehabilitation of Amputees) program...

INTRODUCTION: Cold dissection (CD) and bipolar cautery dissection (BCD) techniques are two common surgical tonsillectomy procedures used in the clinic. Obstruction has become more prevalent as the major surgical indication and is most prominently observed in younger children. CASE REPORT: In this report, we aimed to explain the abovementioned surgical techniques in detail and compare the results in identical twins (monozygote twins). Using low energy electrocautery, irrigating the operation site continuously during cauterization, avoiding unnecessary sutures, and direct cautery to the tonsil bed are all effective measures that have diminished post-op pain in bipolar electrocautery dissection, compared to cold dissection tonsillectomy...

BACKGROUND: There is growing evidence that maximal surgical resection of primary intrinsic brain tumours is beneficial, both by improving progression free and overall survival and also by facilitating postoperative chemotherapy and radiotherapy. Hence, there has been an increase in the popularity of real-time intraoperative imaging in brain tumour surgery. The complex theatre arrangements, prohibitive cost and prolonged theatre time of intraoperative MRI have restricted its application...

BACKGROUND: In patients with relapsed osteosarcoma, the surgical excision of all metastases, defined as second complete remission (CR-2), is the factor that mainly influences post-relapse survival (PRS). Currently a validated follow-up policy for osteosarcoma is not available, both chest X-ray and computed tomography (CT) are suggested for lung surveillance. The purpose of this study is to evaluate whether the type of imaging technique used for chest surveillance, chest X-ray or CT, influenced the rate of CR-2 and prognosis in patients with recurrent osteosarcoma...

Minimally invasive approaches to the central skull base have been popularized over the last decade and have to a large extent displaced 'open' procedures. However, traditional skull base surgery still has its role especially when dealing with a large clival chordoma where maximal surgical resection is the principal goal to maximize patient survival. In this paper, we present a case of a 25year-old male patient with chordoma in the inferior clivus which was initially debulked via a transnasal endoscopic approach...
