Designing a Nasal Lining-Framework Complex for Reconstructing Total Nasal Defects.

Objective: To validate the feasibility of an innovative nasal lining-framework complex (NLFC) for reconstructing total nasal defects.

Study design: Retrospective cohort study.

Methods: This NLFC is composed of forearm flap and support framework. Twenty-four patients were followed up for a minimum of 17 months in 5 centers. Patients' medical history data were retrospectively analyzed. Visual Analog Scale (VAS) of surgeons and patients was used to evaluate the aesthetic effects and self-satisfaction. The Nasal Obstruction Symptom Evaluation (NOSE) questionnaire and Rhinoplasty Outcome Evaluation (ROE) questionnaire were used for functional assessment.

Results: Reconstruction surgeries were all successfully completed. The flaps healed well in all patients, and there were no signs of ischemic necrosis. The healing time of the wound was 10 to 14 days, except for 1 case with infection. The nasal lining was reconstructed and no significant contracture was observed. The average VAS of surgeons was 4.29 ± 0.69 (range 3-5). The mean VAS score of patients was 3.75 ± 0.79 (range 2-5). There was a significant positive correlation between patients' and surgeons' VAS scores (P = .007, r = .5355). The results of the NOSE questionnaire showed that all patients had no obvious ventilation restriction, and only 3 patients mildly felt that the nasal inspirations were slightly insufficient during exercise or exertion. The mean ROE of the patients was 21 ± 1.96 (range 18-25).

Conclusion: This NLFC is suitable for total nasal reconstruction, which can provide effective support to prevent flap collapse and retraction and ensure good nasal ventilation.

Level of evidence: Level IV, therapeutic study.
