The lips are the main aesthetic component of the facial lower third and simultaneously a substantial element for an ideally perceived smile. One of the most accepted and common procedures that is widely used to enhance the shape and contours of the upper lip is the lip lift. With a careful treatment plan and a professional surgery, a lip lift can reliably be used for the reduction of the philtrum height, enlargement of the upper vermilion, improvement of the dental show, restoration of facial aesthetic proportions, and creation of an enchanting smile.

Background: Nasal sill is one of the components of the alar ring, affecting the esthetic outcomes of rhinoplasty; accordingly, we developed a novel technique to adjust defects in this area and compared it with the available techniques.

Methods: Our technique was based on creating a tunnel access to the nasal sill area through an incision made in the lower third of the columella using the open approach or through a nostril base incision in patients, who underwent alar base reduction, followed by insertion of a cartilaginous graft into the marked defect area.

Results: A total number of 54 patients with a defect in the nasal sill area were included in this study.

Piezoelectric tools are the novel ultrasonic methods for effective and safe osteoplasty or osteotomy in comparison with traditional soft and hard tissue approaches using rotating instruments due to lack of microvibrations, ease of control and use, and safer cutting, mainly in complex anatomic areas. Piezoelectric indicates favorable and valuable outcomes based on the immediate postoperative morbidities, even though long-term results have not been investigated. It could be indicated that the piezosurgery in rhinoplasty can be considered as a reliable and safe method and should be taken into account as a part of the surgeon's repertoire for rhinoplasty.
