Three-dimensional modeling of nasal septal deviation.

Area of Science:

• Rhinology and Nasal Surgery
• Surgical Techniques for Septal Deviation

Background:

• Three-dimensional (3-D) septal deviations present challenges in complete surgical correction.
• A classification and treatment strategy for 3-D septal deviations were developed based on model and clinical studies.

Observation:

• A technique was developed to transform 3-D septal L-struts into 2-D structures by incising and overlapping segments.
• This technique was applied intraoperatively in 11 patients, with some requiring septal extension grafts.

Findings:

• Postoperative relief of external nasal deviation was observed in all 5 cases presenting with this symptom.
• Improvement in preoperative breathing difficulties was noted in 7 out of 8 patients.

Implications:

• The described method of creating 2-D L-struts from 3-D septal deformities offers successful correction.
• This technique is particularly advantageous for patients requiring septal extension grafts, ensuring a stable fixation point.
