IMPORTANCE Collapse or compromise of the internal nasal valve (INV) results in symptomatic nasal obstruction; thus, various surgical maneuvers are designed to support the INV. OBJECTIVE To determine the effect on nasal airflow after various surgical techniques focused at the level of the INV and lateral nasal sidewall. DESIGN AND SETTING A fresh cadaver head was obtained and underwent sutur...
Figure ]. A: After the deflected dorsal segment of the septum is separated vertically from the remainder of the septum, a 3.0-mm Skeeter drill is used to create two small holes in the nasal bone on the side opposite the direction of the deflection. B: The ends of the separated septum are sutured into position with a horizontal mattress suture that is passed through the holes in the nasal bones....
INTRODUCTION: The concept of freestyle propeller flaps provides a versatile opportunity for wound closure at any part of the body with minimal donor site morbidity. As experience and familiarity with microsurgical procedures has increased interest in identifying-harvesting perforator flaps originating from known major vessels has become more common. The “freestyle” concept developed by Wei and ...
The purpose of this study was to evaluate the effect of spreader penetration depth on apical microleakage using the lateral compaction method. A total of 96 extracted maxillary central incisors were instrumented using the step-back method, and randomly divided into the following four experimental groups: A) with tug-back and spreader penetration 1 mm short of the working length; B) without tug-...
The objective of this study was to introduce various spreader flap technique modifications to adjust the width of the middle nasal vault in patients who underwent rhinoplasties with humpectomy. Decisive modifications of current spreader flap techniques were performed to allow a more natural restoration of the middle nasal vault and the internal nasal valve after humpectomy. Additional steps pro...
