Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Due to divergence in the literature, the present study aims to compare, through a double blinded randomized clinical trial, two techniques of alar base modifications that will differentiate only by violating or not the alar facial groove.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The surgical technique will be based on a sequential approach based on the 2010 publication Adamnson et al in the Archives of Facial Plastic Surgery "Alar Soft-Tissue Techniques in Rhinoplasty Algorithmic Approach, Quantifiable Measurement of outcomes will be performed by trained and blinded research team members for intervention allocation. Patients will be evaluated at the preoperative visit, and will return to consultations on days 7, 14.30, 60, 90.360 postoperative days, when they will be photographed at the incidences, frontal, ¾ profile, basal, between tip with Eyebrows. At the base line and at 90 postoperative days the following outcomes will be measured: Stony Brook Scale , ROE Scale, Visual Analogue Scale - Satisfaction with aesthetic aspect of the nose, Visual Analogue Scale Intensity of nasal obstruction and NOSE Scale For the comparison of continuous variables will be compared using Student's t test for independent samples or Mann-Whitney non-parametric test, when appropriate. Multivariate analysis will be performed to control confounding factors.

Alar facial groove Incision
Alar Base surgical modification with surgical inions in the alar facial groove
Alar facial groove incision
All procedures related to alterations in the alar base will be based on an algorithm proposed by 2010 Adamnson et al lar Soft-Tissue Techniques in Rhinoplasty Algorithmic Approach, Quantifiable Guidelines, and Scar Outcomes From a Single Surgeon Experience ,published at Archives Facial Plastic Surgery in which a sequential approach is used, evaluating step-by-step surgical needs. Initially, the alar base can be reduced by removing tissue from the nasal sill. At this step, modifications at the shape or the width of the nostrils can be done. After that, a rotation-advancement flap is made, and the sill defect is closed. The nasal flair is then assessed and tissue from the alar border can be removed if needed. The incisions not spare the alar facial groove.
Alar facial groove spared
Alar Base surgical modification with surgical incisions 1mm above the alar facial groove
Alar facial groove spared
The technique is the same of the Alar facial groove incision intervention group, but the incisions spare the groove. The incisions will be at 1 mm above the groove.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
The alar base modification is indicated when the columella-alar distance is greater than the intercanthal distance, when there is presence of asymmetries between the nostrils or its size is too width. In corrections of overprojected noses, there may be enlargement of the base of the alar, with an indication of reduction of the width of the alar at the end of the procedure.
