Single Cell Sequencing of Tonsillar Tissue in Children With OSA

Subjects who are diagnosed to have OSA with adeontonsillar enlargement will undergo adenotonsillectomy if it is clinically indicated. Adenotonsillar tissue will be obtained for single cell sequencing. Controls will be non-OSA subjects (with PSG OAHI \<1/hour) who undergo adenotonsillectomy for other reasons such as recurrent tonsillitis.
