Background:
The Columellar Auto-Strut Technique (CAST) is a refined modification of the Tongue-in-Groove (TIG) method, designed to provide stable nasal tip support while maintaining aesthetic flexibility. This study evaluates the clinical outcomes of CAST in septorhinoplasty (SRP).
Methods:
A retrospective analysis was conducted on 78 patients who underwent SRP using CAST. Nasal tip projection (Goode ratio), nasolabial angle (NLA), and subjective tip stiffness were assessed preoperatively and postoperatively.
Results:
The mean NLA increased from 84.3° ± 5.2° to 99.8° ± 4.8° (p < 0.001). The Goode ratio improved from 0.58 ± 0.06 to 0.63 ± 0.01 p = 0.003). The mean VAS score for nasal tip stiffness was 7.1 ± 1.1. No significant cases of nasal tip deviation or nostril asymmetry were reported.
Conclusions:
The CAST technique offers stable nasal tip support with predictable outcomes, preserving both function and aesthetics. Further studies with larger sample sizes and long-term follow-up are needed to validate its effectiveness in routine SRP.

The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
