Background: Obstructive sleep apnea (OSA) is a common health
problem affecting a large number of people all over the world with
great psychological and physiological burdens. The aim of this
study is to investigate the effect of implantation of septal cartilage
and platelet rich plasma in the soft palate as a new technique in
treatment of obstructive sleep apnea and snoring. Patients and
Methods: This study included 30 Patients with mild to moderate
OSA were divided into two groups (A and B) each was 15. Group
A: n=15(Tonsillectomy and palatal implantation with septal
cartilage). Group B: n=15(Tonsillectomy and platelet rich plasma
(PRP) injection). Results: This study found that both techniques
improved day time sleepiness with reduction of apnea-hypopnea
index (AHI), also there was marked improvement in radiological
parameters in the form of increase of the antro-posterior diameter
and retro palatal cross-sectional area but also We found superiority
of group A over group B in improvement of these parameters that
in Group A: success rate was 86.6% while in Group B: it was 80%. No major postoperative
complications were recorded. Conclusion: palatal implantation of septal cartilage and platelet
rich plasma, both are effective as a treatment of obstructive sleep apnea due to retro-palatal
collapse.
