background nasal valve collapse and especially internal nasal valve insufficiency is a common cause of nasal airway obstruction. this study compares the effects of spreader graft and overlapping lateral crural technique on rhinoplasty by rhinomanometry. methods fifty patients were randomly assigned into two groups and underwent spreader graft or overlapping lateral crural technique. objective a...

background: the final objective of root canal therapy is to create a hermetic seal along the length of the root canal system. for this purpose, many methods and materials have been introduced. the purpose of this study was to compare the apical microleakage in a new obturation technique (true-tug-back) with two other obturation techniques (lateral condensation and chloroform dip technique). met...

objectives: aim of this study is to investigate the initial effect of taping technique on wrist extension and grip strength and pain of individuals with tennis elbow. methods: fifteen patients (10 men and 5 women with 42.53 years) on their dominant arm participated in this study. outcome measures were wrist extension and grip strength and pain taken before and immediately after application of t...

Introduction After the loss of teeth in the posterior maxilla, the thickness or vertical height between the alveolar crest and maxillary sinus may be insufficient to place dental implants. At present, maxillary sinus lifting has become a widely used technique for augmenting bone tissue volume in the maxilla. Various surgical techniques can be applied to achieve a sufficient bone volume in order...

A technique, the "Loma Linda pouch," is introduced for repairing the perforated maxillary sinus membrane during sinus grafting procedures. A collagen membrane is placed against the perforated site and subsequently covers the internal surface of the maxillary sinus. The collagen membrane is then folded along the lateral access window to form a pouch that surrounds and isolates the graft material.

A 4D-Var data assimilation technique is applied to a ORCA-2 configuration of the NEMO in order to identify the optimal parametrization of the boundary conditions on the lateral boundaries as well as on the bottom and on the surface of the ocean. The influence of the boundary conditions on the solution is analyzed as in the assimilation window and beyond the window. It is shown that optimal cond...

Cervical anterior foraminotomy (AF) is an anterior surgical technique for the cervical spine aimed to decompress intervertebral foramen and lateral side of the spinal canal. This technique aims to remove the offending lesion, either a disc fragment or osteophyte compressing the neural structures, via a bony window at the uncovertebral area; while preserving the structure and functions of the in...

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...

BACKGROUND Patients with resorbed edentulous alveolar ridges in the posterior maxilla often require lateral window sinus augmentation procedures prior to implant placement. Lateral window sinus augmentation procedures can produce incomplete bone augmentation as consequence of surgical and healing complications producing unusual and complex sinus anatomy. Although incomplete bone formation after...
