| Congenital Malformation of Ossicles |
|
Definition
-deformity during fetal devel.
-fusion of some/all structures
-can have max Conductive loss (60dB)
-Type As tympanogram
-Good results w/ prosthesis +/or h. aids |

Term
| Ossicular Disarticulation |
|
Definition
-Cause: trauma / cholestiatoma
-Incudostapedial (joint btwn stapes & incus)
-Minimum loss +/- 30-40dB, max 60dB
-Management: surgical repair (put sleeve on joint), prosthesis
-Tympanogram: floppy, Ad type.
-Note: may get SN at 4k b/c acoustic trama of hitting head). |

Definition
-Middle ear cyst related to chronic O. Media.
-Pars flaccida suckd in by -pressure, made of skin, sloughs off, ad infinitum
-HL: mild - severe (depends on locale)
-management: surgical (can impact chorda tympani, ossicles, etc)
-NOTE: low frequencies can be preserved,
-Tympanogram: variable b/c cyst can be all over the place |

Definition
-ME ossicles overgrown w/ bone (usu. at footplate of stapes)
-Stiffens ossicular chain
-Common in women during child b. year, can be related to pregnancy, etiology unknown (prob genetic)
-HL: progressive, notch at 2k (Carhardt's notch) due to resonant freqs.
-Tympanogram: Type As
-Manage: surgery, stapedectomy, stapeotomy |

| Eustachian Tube Dysfunction |
|
Definition
-Cause: infection of nasopharynx (upper respiratory, allergies, inflammation, swelling --> air doesn't turn over, get neg. pressure in ME.
- Uni- or bi- lateral; mild loss.
-Tympanogram type c.
-Management: follow and retest, decongestant... could be getting better.
-CONCERN: kid with SN loss, this could really impact life, may treat more aggressively.

Definition
-Most common HL in children (80% have at least one bout); most prev. childhood disease; most common reason for dr. visit; myringotomy was most common surgery; billion $ anti-bio biz.
-Predisposing: males; race (+ alaskan natives, - asians); season (share germs); climate; age (12 - 24 mnts); environ (2nd hand smoke?); genetics; day care (share germs); bottle fed (maybe milk allergies)
-Dianosis: otoscopy, type b tympanogram; audiometry
-Sequence: u. resp. infection --> E tubes inflame --> can't vent --> air depletes --> neg. pressure --> mucous secreted --> infection invades ME --> infection w/ infusion
Manage: decongestants, anti-bio, myringotomy, lance TM, Pressure Equilization Tubes (PE) (grommeted tubes in TM) |
