Alar rim deformities are among the most common problems affecting patients undergoing both primary and secondary rhinoplasty. They can be caused by several factors such as congenital hypoplasia or malpositioning of the lateral crura, and from acquired surgical weakening during rhinoplasty. Even though altering the structure of the lower lateral cartilage complex can help prevent and correct alar rim deformities, this may not always allow for sufficient control of the alar rim. Alar contour grafts have been proven efficacious not just in the treatment of specific rim deformities but also in their prevention. In this article, the authors present four types of alar contour grafts and discuss their expanded role in the prevention and treatment of alar rim deformities.

The external nasal valve is the anatomic structure formed by the caudal septum, alar rim, medial crura of the lower lateral cartilage, and nasal sill at the level of the nasal vestibule. Evaluation of external nasal valve dysfunction is dependent upon a thorough history and physical examination. Symptoms and quality of life impact are the main drivers for patients to seek out clinical evaluation.

Objectives: To compare longitudinal improvement in nasal obstruction quality-of-life outcomes between medial flap turbinoplasty (MFT) and inferior turbinate submucous resection (SMR) concurrently performed with functional septorhinoplasty.
Methods: Retrospective review of a prospectively collected cohort of patients undergoing functional septorhinoplasty between 2015 and 2022 at a tertiary academic center. Outcomes were assessed using the Nasal Obstruction Symptom Evaluation (NOSE) questionnaire preoperatively and over 12 months postoperatively.

This study aimed to investigate the treatment methods used for alar rim problems during the last 5 years and the efficacy of pull-out sutures on the outcomes. A retrospective study was conducted on patients with alar contour grafting and pull-out suture procedures between 2018 and 2023. Patient records and images, such as retraction or collapse, were evaluated before surgery.

The airway must not be ignored in cosmetic rhinoplasty operations, and it is important to address the 4 areas that restrict airflow namely the septum, the turbinates, the mid-vault, and the external nasal valve. Numerous techniques exist that treat these areas without any compromise in esthetic outcome. Techniques include lateral wall suture suspension methods, specialized sutures of the lateral crus, and articulated alar rim grafts.

Article Synopsis
- Reconstruction of the nasal ala poses challenges such as loss of the nasofacial junction and compromised blood supply, while aiming for good cosmetic results.
- A new surgical technique using a melolabial-based transposition island pedicle flap offers an effective alternative to traditional methods, allowing for a single-stage procedure.
- This flap technique, which involves careful dissection from the nasolabial fold, is particularly suitable for patients with specific nasal defects and results in minimal complications and a cosmetically pleasing outcome.
