AbstractIntroductionThe position of the lower lateral cartilages (LLC) is closely related to the function of the external nasal valve (ENV). When there is a cephalic malposition of these cartilages, the nasal alae have inadequate support, which leads to ENV insufficiency during deep inspiration.Methods Retrospective study with 60 patients evaluated: the positioning of the LLC and the occurrence of ENV insufficiency; the effectiveness of structuring the medial and lateral walls of the ENV; and…

Scroll Ligament Preservation and Improvement in Nasal Tip with the Room Concept

In the present “superior-based sliding flap” technique, the LLC remained thick and stable; therefore, a particular functional improvement was achieved, and the scroll ligament was preserved, so this technique prevented the accumulation of skin at the nose tip.

Lateral Suspension Technique in Treatment of Lateral Crus Malposition Belada Technique.

The lateral crus did not dislocate, did not shift to cephalic and no infection developed in any of the patients, and the technique authors developed to prevent complications was introduced.

Rhinogoniometer: Validation of an Instrument for Rhinoplasty

The rhinogoniometer was validated, an innovative surgical instrument that allows for diagnosing the position of this cartilage intraoperatively and was shown to be reproducible with different surgeons.

Comparative Functional Effect of Alternative Surgical Techniques Used in Rhinoplasty.

Spreader grafts increase peak nasal inspiratory flow (PNIF) more significantly than other surgical techniques used for dorsal mid-vault reconstruction and should be preferred over other techniques whenever an improvement of nasal airflow is required.

Inaccuracy of Standard 2D Photography for the Diagnosis of Cephalic Malposition of Lateral Crural Cartilages.

The overall frequency of LCCM seems to be lower than the previously reported frequency, and surgeons must focus on the best contouring and function rather than solely correcting angles and rotations.



Preoperative and postoperative assessment of external nasal valve in rhinoplasty

Structuring the nasal alae with a lateral crural strut graft and/or alar contour graft was proven effective to correct external nasal valve insufficiency in 90% of the cases and to provide better aesthetic proportions and nasal contour.

The Incompetent External Nasal Valve: Pathophysiology and Treatment in Primary and Secondary Rhinoplasty

The external nasal valve may be a substantial cause of nasal airway obstruction in some patients; its pathophysiology and treatment are discussed in primary and secondary rhinoplasty.

Overresection of the Lower Lateral Cartilages: A Common Conceptual Mistake with Functional and Aesthetic Consequences

Overresection of the lower lateral cartilages to narrow the tip in individuals with thick skin is frequently followed by dysfunction of the external nasal valve and aesthetic deformities and is completely rebuilt.

Use of alar batten grafts for correction of nasal valve collapse.

Alar batten grafts are effective for long-term correction of internal and external nasal valve collapse that is not complicated by intranasal scarring in the region of the nasal valve, loss of vestibular skin, or excessive narrowing at the piriform aperture.

The procedure described herein is a modification of the Sheen technique that can be done as either an open or a closed procedure, particularly valuable in decreasing the overprojecting nasal tip and preserving the equal height of the alar domes while widening the angle of divergence of the lateral crus.

The tongue-in-groove technique in septorhinoplasty. A 10-year experience.

The TIG technique provides a direct, effective solution to columellar show and is a reliable, reproducible method for achieving predictable tip rotation and projection when used in conjunction with septoplasty techniques.

Extended Alar Contour Grafts: An Evolution of the Lateral Crural Strut Graft Technique in Rhinoplasty

Extended alar contour grafts are a versatile technique to optimize tip shape and orientation by combining the many positive attributes of lateral crural strut grafts and alar CONTOUR grafts.

Repair of Lateral Wall Insufficiency

The LWI grading system enables surgeons to localize LWI, tailor the surgical treatment to the patient, and monitor improvements in the postoperative period, as well as establish an algorithm for treatment of LWI by evaluating subjective and objective outcomes of patients who underwent LWI repair.

The alar contour graft: correction and prevention of alar rim deformities in rhinoplasty.

The alar contour graft provides the foundation in the patient undergoing primary or secondary rhinoplasty for the reestablishment of a normally functioning external nasal valve and an aesthetically pleasing alar Contour graft.

The Frequency of Surgical Maneuvers during Open Rhinoplasty

The senior surgeon has found that common incorporation of certain maneuvers offers more consistent, aesthetically pleasing, and superior functional outcomes in a single surgeon's practice.
