It would be best if you could post the part. My first approach is to try and delete the smaller ones one at a time. This usually blends the surround few surfaces.
But to take it further I would want to play with it a bit.
You might want to give the "Redefine" option a try (found in the Surfacing toolbar). This may allow you to merge those faces together while controlling the edge conditions. Worth a shot.
Try the Inspect tab>Geometry Inspector to identify small faces and delete what you can.
Then modify your study advanced settings Geometry check = Warning Only.
