Lateral Crural Turn-Up Flap for Increasing the Volume of Cartilaginous Nasal Sidewall in Closed-Approach Dorsal Preservation Rhinoplasty.

Background: Dorsal preservation rhinoplasty can also be applied in crooked nose cases. This article describes a lower lateral cartilage-based flap (lateral crural turn-up flap) used to correct cartilaginous nasal sidewall asymmetries. It was aimed to introduce a flap to be used in crooked nose cases operated with dorsal preservation rhinoplasty and to show possible modifications of this flap.

Transection of Pitanguy's Midline Ligament to Avoid Supratip Depression in Closed-Approach, Low-Septal-Resection Dorsal Preservation Rhinoplasty.

Background: Supratip depression is a common complication after preservation rhinoplasty.

Objectives: This aim of this paper was to present a simple surgical maneuver to prevent supratip depression.

Methods: Thirty-six patients who underwent closed-approach, low-septal-resection dorsal preservation rhinoplasty between January and June 2021 were included in this retrospective study.

Fixation of the Cartilaginous Vault with Barbed Suture in Closed-Approach High-Septal-Resection Dorsal Preservation Rhinoplasty.

Fixation of the cartilaginous vault is an important maneuver in preservation rhinoplasty to reduce hump recurrences. This paper presents a cartilaginous vault fixation technique with a barbed suture. Forty-six patients who underwent closed-approach high-septal-resection dorsal preservation rhinoplasty between August 2019 and March 2020 were included in this retrospective study.

The Effect of Ultrasonic Liposuction Energy Levels on Fat Graft Viability.

Background: The use of fat obtained from ultrasound-assisted liposuction is popular. However, no study has considered the effect of different energy levels on fat grafts.

Objectives: We hypothesized that different ultrasonic energy levels could change the fat graft viability.

Flexible Tongue-in-Groove Technique and Its Effectiveness Compared to Classic Tongue-in-Groove and Columellar Strut Graft Techniques: A Retrospective Analysis of 237 Open Rhinoplasty Cases.

Background: The medial crura are almost always supported in tip surgery using columellar strut graft placement or tongue-in-groove suturing to the caudal septum. In this study, the authors present a modified tongue-in-groove (called "flexible tongue-in-groove") technique.

Methods: A total of 237 patients who underwent open rhinoplasty between January of 2016 and June of 2018 were included in this retrospective study.

A composite neural network model for perseveration and distractibility in the Wisconsin card sorting test.

A composite artificial neural network model is proposed to simulate the performance of the Wisconsin Card Sorting Test. The Wisconsin Card Sorting Test is a test of executive functions where prefrontal deficits are matched to some quantitative measures such as percentage of perseverative errors and number of failures to maintain set. In this work, the proposed model is used to simulate the performances of healthy subjects and patients with prefrontal involvement particularly on these measures.
