Introduction: This study was performed to evaluate the correlation between the objective and subjective sensation of nasal patency, assessed through a validated questionnaire, the Italian version of the NOSE scale, and the rhinomanometric results in a large cohort of patients complaining about nasal obstruction.     Materials and Methods: Data was obtained from a total of 233 adult patients, ...

background: nasal fracture is a common fracture due to trauma. gold standard method in diagnosis of nasal fracture is clinical examination and radiography is used in legal situation. recently, ultrasound is recommended as a noninvasive and simple method in diagnosis of nasal fracture. this study investigates the role of ultrasound in diagnosis of nasal fracture. methods: 126 cases with suspecte...

Objective- One of the important causes of nasal fracture is a trauma that can be diagnosed in clinical examinations and diagnostic imaging but it should be noted that radiography may show false fractures in the nose. This study evaluates the value of ultrasonography in the diagnosis of nasal fractures and compared it with plain radiography. Design- Retrospective study. Animals- 12 d...

Finishing methods of machining superhard composite’s working elements based on cubic boron nitride BL group are considered. The results the microgeometry formation research cutting inserts’ surfaces during by free powders synthetic diamond, grinding wheels and a method vibro-magnetic-abrasive (VMAM) presented. It is shown that VMAM friction between abrasive particles result in microremoval mate...
