A frontotemporal craniotomy is usually performed using a "keyhole," made at the union of the zygomatic arch and frontal bone. Consequently, skull depression may occur postoperatively, leading to temporal area deformities and poor cosmetic results. To prevent these complications, we describe our technique for frontotemporal craniotomy using an osteotome to prevent cosmetic deformities. After the...

Direct removal of beak-type ossification of posterior longitudinal ligament at thoracic spine (T-OPLL) is a challenging surgical technique due to the potential risk of neural injury. Slipping off the cutting surface of a high-speed drill may result in entrapment in neural structures, leading to serious complications. Removal of T-OPLL with an ultrasonic osteotome, utilizing back and forth micro...

BACKGROUND The ultimate goal of rhinoplasty is to achieve a controllable, reliable and an aesthetically pleasing result. Various approaches and instruments have been introduced for the correction of the bony walls of the nose to improve predictability of the procedure and to minimize the associated trauma. We conducted a cadaveric study comparing the results of osteotomy of the nasal wall using...

Purpose: To present a new technique for effective, rapid, and safe pterygomaxillary dysjunction in the context of a minimally invasive Le Fort I protocol and to provide the authors’ preliminary experience. Materials and Methods: In total, 1,297 consecutive patients underwent Le Fort I osteotomy as an isolated procedure or in combination with mandibular surgery. In all cases, the “twist techniqu...

The combination of postextraction ridge resorption [1] and pneumatization of the maxillary sinus [2, 3] often limits the bone available for implant placement in the posterior maxilla. Fortunately, the lateral and transcrestal approaches to sinus floor elevation (SFE) and augmentation can reproduce adequate subantral bone volumes for implant-supported rehabilitation in this region. The lateral w...

Implant placement in the posterior maxilla often requires elevation of the sinus floor, which can be achieved through either the modified Caldwell-Luc or the crestal osteotome technique. The objectives of this study were to evaluate (a) the resistance to perforation of maxillary sinus membranes obtained from formaldehyde-fixed cadavers in vitro, (b) the frequency and extent of membrane perforat...

PURPOSE A novel technique for transcrestal guided sinus lift elevation (TGSL), is described underlining the step by step surgical protocol. MATERIALS AND METHODS TGSL modified osteotome technique was planned by the NobelProcera(®) Software Planning Programm (Nobel Guide, Nobel Biocare AB) and performed by stereolitographic template. The depth of the planned osteotomy was determined precisely ...

Aim: The aim of the study was to evaluate retrospectively maxillary sinus functions and complications by using generally accepted diagnostic criteria with lateral window and osteotome sinus floor elevation (OSFE) procedures followed by dental implants placement. Materials and methods: A group of 60 patients in whom a SFE with the two procedures (lateral window and OSFE) followed by dental impla...
