For Chronic Sinusitis, go down to 'methods' on this article: http://www.omicsonline.org/2155-6121/2155-6121-2-109.php
It gives techniques for draining the sinuses and nasal passages. I had to look up the anatomical terms on wikipedia, but I tried it once on myself (looking at the ceiling) and there was definitely increased drainage and some noticeable clearing up. Some of the steps might be a little difficult to do on yourself, but still possible - though your thumbs might have to point the other way.
