Three-Dimensional Quantification of Nasal Septum Components: A CT-Based Analysis.

Area of Science:

• Anatomy
• Surgical Planning
• Medical Imaging

Background:

• The nasal septum is crucial for nasal airflow and facial aesthetics.
• Accurate anatomical knowledge is vital for successful septorhinoplasty.
• This study focuses on detailed morphometrics of the nasal septum.

Purpose of the Study:

• To collect precise morphometric data of key septal structures.
• To investigate correlations between surgical landmarks of the nasal septum.
• To enhance preoperative planning for septorhinoplasty.

Main Methods:

• Retrospective observational study of 50 adult Turkish patients undergoing primary septorhinoplasty.
• Analysis of preoperative CT scans to measure septal cartilage, vomer, and ethmoid perpendicular plate dimensions.
• Evaluation of caudal septum length and its correlation with other anatomical features.

Main Results:

• Significant sex-based differences were observed in the volume of septal cartilage.
• A positive correlation was found between caudal septum length and the length of the cartilage-perpendicular plate of the ethmoid (PPE) junction.
• Detailed morphometric data were obtained for surgical landmark analysis.

Conclusions:

• The anatomical measurements derived can inform graft design in septorhinoplasty.
• Findings contribute to developing individualized preoperative strategies for patients.
• Precise data enhances surgical planning for improved outcomes in septorhinoplasty.
