Digital Imaging in Rhinoplasty
Imaging in facial plastic surgery is becoming common. With the advances of digital imaging software, modifications of preoperative images for rhinoplasty patients can help to predict outcomes. The primary objective of this study was to determine whether preoperative digital image modification in rhinoplasty patients is useful in predicting postoperative outcomes... Read More »

Temporal Fascial Periosteal and Musculoperiosteal Flaps in the Pig: Design and Blood Flow Assessment
The availability of a vascularized periosteal flap with bone-forming potential could greatly enhance the reconstructive capabilities of the craniofacial surgeon. Previous observations seem to indicate that the bone-forming potential of periosteal flaps depends on the vascularity of the flap... read more »

Comparison of Laser Doppler Flowmeter and Radioactive Microspheres in Measuring Blood Flow in Pig Skin Flaps
Laser Doppler flowmetry is a noninvasive technique commonly used to monitor skin perfusion after free-tissue transfer or replantation in reconstructive surgery. Several investigators have expressed concern about the reliability of the quantitative value provided by laser Doppler flowmeters (LDF) and the extent to which they reflect nutrient blood flow... read more »

Nasal Airway Volume and Resistance to Airflow
In keeping with the concepts of evidence-based medicine, various objective measuring techniques are used for assessment of nasal airway patency. In modern rhinological practice and research, rhinomanometry and acoustic rhinometry are probably the most widely used techniques. The goal of the present study was to determine whether there is correlation between rhinomanometrically derived nasal airflow resistances and acoustic rhinometrically derived nasal airway volumes... read more »

Predictive Value of Computer Imaging in Rhinoplasty Surgery
Rhinoplasty is one of the most common procedures performed by facial plastic surgeons. For many years, documentation of an individual's nose and the relationships of the face has been carried out using various techniques of imaging from silhouettes, to photography, and now more recently digital imaging... read more »

Deprojecting the Nasal Tip
The overprojected nasal tip, commonly referred to as the "Pinocchio" nose, is a relatively uncommon but challenging deformity. Surgical correction of the nasal tip is most difficult and the least predictable component of rhinoplasty surgery. The goal of the nasal aesthetic surgeon is... read more »
