| 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. |
| Chronic suppurative otitis media is chronic suppuration of the middle ear cavity associated with a defect in the tympanic membrane. |
| Swabbing a specimen should only be performed if the tympanic membrane has ruptured. |
| The skin of the cartilaginous canal is affected initially, with more severe disease affecting the concha, bony canal and tympanic membrane. |
| The remainder underwent Type III tympanoplasty with the tympanic membrane placed directly over the stapes suprastructure. |
