Abstract Purpose: to evaluate the safety and the efficacy of a modified Z-palatoplasty (ZPP) technique in management of post-surgical nasopharyngeal stenosis (NPS), describing its steps and results. Methods: This prospective study was conducted on patients with snoring± OSA due to acquired post-surgical NPS of grade Ι and ΙΙ. Surgical repair using a modified ZPP was employed on the patients and the pre and postoperative results were statistically compared and adverse events were recorded. Results: The grade of NPS improved significantly postoperatively (p= 0.00136) throughout a follow up of one year. Postoperatively, there was statistically significant improvement of AHI (p= 0.0005), VAS of nasal obstruction (p<0.0001) and VAS of snoring (p<0.0001). While transient VPI and dysphagia disappeared within 3 months postoperatively. Conclusion: The utilized procedure appears fast, low cost, and easily applicable, and it does not require implants, special tools or suture materials. Furthermore, it gives promising results, with tolerable pain, and rapid recovery without significant or persistent complications.
