Reconstruction of the nasal septum using polydioxanone plate

Area of Science:

• Rhinology
• Plastic Surgery
• Biomaterials Science

Background:

• Severe septal deformities often require complex surgical correction.
• External septoplasty offers an approach for significant septal reconstruction.
• The mechanical stability of cartilage grafts is crucial for successful outcomes.

Observation:

• A technique using a resorbable polydioxanone plate attached to nasal septal cartilage was developed for external septoplasty.
• This method was applied to 396 patients with severe, often post-traumatic, septal deformities.
• Autologous septal cartilage, or auricular conchal cartilage when necessary, was used as free grafts secured to the polydioxanone plate.

Findings:

• The polydioxanone plate provided mechanical stability to the grafted septal cartilage fragments until healing.
• All patients reported improved nasal airflow and satisfactory cosmetic results.
• No immediate or long-term complications, such as bleeding, necrosis, or septal perforation, were observed.

Implications:

• The resorbable polydioxanone plate is a useful adjunct in external septoplasty for severe septal deformities.
• This technique supports the nasal dorsum and facilitates cartilage graft integration.
• The findings suggest a safe and effective method for improving nasal function and aesthetics in challenging cases.
