If you have the image processing toolbox, use strel, imclose and imfill.
Also look at bwareaopen. You can apply this to the complement of the image to remove holes with a certain area or less, then take the complement again.
If your image is logical, the complement is obtained using the ~ operator. If it is binary numeric with values 0 and 1, the complement is 1 minus the image.

I did this just recently for someone here: http://www.mathworks.com/matlabcentral/answers/119328#answer_126374. She wanted to get rid of tiny black holes in here binary image but not the bigger ones. See the post for images and code. Post an image if you want more exact advice.
