Internal Nasal Valve Expanding Graft for Middle Vault Reconstruction.

Abstract

Various surgical techniques and approaches for addressing nasal valve collapse have been described in the literature. Still, new techniques continue to be developed and old techniques continue to be improved upon. The aim of the present study was to validate the use of the internal nasal valve expanding graft for middle vault reconstruction and to review the authors' experience using this technique. A total of 32 patients who underwent middle vault reconstruction were retrospective reviewed. Analysis using Visual Analogue Scale (VAS) and Nasal Obstruction Symptom Evaluation (NOSE)-scale was performed pre- and postoperatively. Visual Analogue Scale scores for nasal airflow per side were collected on a 10-point scale, with 1 indicating total obstruction and 10 indicating a perfect nasal airway. Nasal Obstruction Symptom Evaluation scale was used to assess nasal obstruction. Minimum follow-up period was 6 months after the operation. Pre- and postoperative VAS scores were used to assess degree of nasal valve collapse according to examination findings. It was significant that there was improvement in nasal valve collapse after surgery (P < 0.05). Based upon pre- and postoperative calculations made using NOSE scores, there was significant improvement regarding nasal blockage or congestion, troubled breathing and sleeping, and air through nose during exercise, respectively (P < 0.05). No complications in terms of septal perforation, hematoma, synechiae, or infection that required further intervention were noted at postoperative follow-ups. In conclusion, internal nasal valve expanding graft has now been shown to be successful for middle vault reconstruction in a group of appropriately selected patient.
