| Chronic suppurative otitis media is chronic suppuration of the middle ear cavity associated with a defect in the tympanic membrane. |
| Clearance of the obstruction showed that the tympanic membrane was compressed against the promontory. |
| The most common cause of the type B tracing is decreased mobility of the tympanic membrane secondary to middle ear fluid. |
| However, this resolution frequently required myringotomy or followed spontaneous perforation of the tympanic membrane. |
| If the physician was unable to completely visualize the tympanic membrane 15 minutes later, the ear was irrigated with 50 ml of tepid water. |
| The risk of ototoxicity is not as much of an issue with the intact tympanic membrane. |
