Enter X-mode in the spikes near the door. Release forward to make Samus move forward at a rate of 1 pixel per frame. After passing the third Yapping Maw, when Samus appears to move forward, this is the indication that the camera scroll has locked against the opposite side of the room, which is a good cue for when to stop, by holding forward again. To avoid taking another spike hit, press jump, then release dash to exit X-mode while jumping.
