122 Section IV ■ Miscellaneous Sampling

11. If more drainage is required, a myringotomy blade can

be used to widen the opening. This will close in 48 to

72 hours.

F. Complications

1. Most common is bleeding from canal wall. This usually will stop spontaneously, but is preferably avoided.

2. TM perforation that persists. Initially, this is may be

helpful for drainage and ventilation of the middle ear

space.

3. Disruption of the ossicles from malpositioned needle

(see B1 and D5)

4. Major bleeding from dehiscent jugular bulb or carotid

artery (6); rare.
