Guest guest Posted August 13, 1999 Report Share Posted August 13, 1999 For a conductive loss they are looking for a break in the conductive chain that would show up on the scan. Like, for instance, if there was a malformed bone or a missing bone. There might be a surgical remedy in that case. For a sensorineural loss I don't think that they would do a CAT scan but I might be wrong about that. > >Excuse my ignorance, but what is typically the reason to get a CAT scan?

CT scans are very useful in diagnosing mondini's syndrome. This is where the cochlea doesn't have the full number of turns, or has other abnormalities. One of the things that can occur with mondini's is where the bone that separates and protects the cochlea from the internal auditory canal or a wave in the cerebral spinal fluid in that canal, does not form completely. There can be either a hole in that bone, or the bone may not be there at all and there is only a membrane. This is what our son's CT showed. For us, it was very important to know because with this, if our son receives a blow to the head that causes a wave of fluid in the canal, this wave is transferred into the fluid inside the cochlea. If this happens (not a big " if " , more like a " when " ) more hair cells are damaged, exactly as if our son were standing near an explosion. This is why our son's hearing loss is progressive. While we couldn't put our son in a protective bubble for his entire life, there are things he should avoid to help maintain his hearing as much as possible: soccer, football, hockey, etc. Actually, now that he has a CI, for the first time in his life we can look forward to stable hearing and I don't have to wonder when he's going to lose another chunk.

This is from my hubby's page: The Difference Between MRI & CT http://members.tripod.com/listenup/ct_mri.htm CT is very good for imaging bone structures. In fact, it's usually the imaging mode of choice when looking at the inner ears. It can easily detect tumors within the auditory canals and can demonstrate the entire cochlea on most patients.

Guest guest Posted August 15, 1999 Report Share Posted August 15, 1999 I've been reading w/ great interest the posts related to conductive hearing losses. My daughter has a bilateral conductive hearing loss suspected to be due to a bilateral fixation of the stapes. The CT scan can be used to identify if the ossicular chain is intact (if all the bones are present, properly formed) but it can't tell if it is functioning. My daughter was diagnosed late (age 4) and at 9, is delayed in terms of her speech, language, academic and social development so I certainly advocate early amplification for this type of loss. The conductive loss responds so very well to amplification because distortion isn't usually an issue. A good reference for those of you looking for a knowledgeable doctor is Dr. Jahrsdoerffer who has a long and impressive career specializing in the surgical correction of outer and middler ear anomalies. He is at UVA and also comes to the Texas Ear Institute in Houston on a regular basis for those of you in those to geographical regions. I will get my files out and look up his phone number and post it. We were very impressed with his care and expertise and his logical and cautious approach to surgery.

Guest guest Posted August 15, 1999 Report Share Posted August 15, 1999 .. I'm pretty much in denial still, just waiting for her hearing to all of a sudden be normal. What's wrong with me! there is nothing wrong with you!!!! Being in denial is very much a normal emotion when you are first thrown into this!!! Believe me I have been dealing with this for the past 12 months, and still every morning when I see my son, I hope that by some miracle his hearing has returned!!! But it will get easier, and when you think you are about to fall apart the people here on this listserv are here for you, we know exactly how you feel so please lean on us if you need to.

Were they speaking at all, or just delayed? My daughter is almost 3 years old, she speaks in sentences but it is not understandable to a lot of people although after a while you can kind of figure it out. She had her adenoids removed recently and her second set of PE tubes put in but I haven't noticed any change in her language since then and it's been a month already. I guess my question is, what does the speech of a hearing impaired child sound like? There probably is no answer to that question since there are so many degrees of hearing loss...I'm just getting so anxious about knowing if my daughter has a real hearing loss or not. I'm pretty much in denial still, just waiting for her hearing to all of a sudden be normal. What's wrong with me! Quote Link to comment Share on other sites More sharing options...
Guest guest Posted August 15, 1999 Report Share Posted August 15, 1999 Hi - First off, to answer your questions, nothing is wrong with you! All the feelings of confusion, fear, etc. are completely normal. Diagnosing a hearing loss in a young child can be a long, confusing, frightening, and frustrating experience. Wish there was a litmus test! My daughter has a moderate/moderately severe hearing loss--most severe in the low frequencies. She only had a couple of sounds/words at age 3. Now, at 9 she has language skills of approximately a 7 year old, with her syntax being the most obviously delayed area of language. Her articulation is fine at the word level but in conversation she can be hard to understand. She tends to delete the morphological markers on words (-ed, -ly, -ing, -s) and she has a " hypernasal " sound quality. I am also a speech-language pathologist by the way. As you said, each hearing impaired child is different, just like each non-hearing impaired child is different, so it's hard to " predict " speech and language development (just like I don't think you can prejudge what the child's ultimate " reading level " will be). If your child is speaking in sentences at three then that is wonderful! Delayed articulation, to me, is less of a concern than delayed language. If you haven't already, ask your school about getting her a speech-language evaluation to see if she needs speech therapy. Hang in there!

Guest guest Posted August 15, 1999 Report Share Posted August 15, 1999 My son had a catscan early on to check for malformation of the cochlea.

Guest guest Posted August 17, 1999 Report Share Posted August 17, 1999 , Deleting final consonant sounds is a very common speech error in young children and especially so in children with hearing impairment. Next time you go see your audiologist, ask him/her to show you the " speech banana " and overlay it on Lexi's audiogram (assuming you can get a good one done!) The " speech banana " is an audiogram w/ the speech and environmental sounds plotted that shows you at what frequency/intensity level each sound is heard. It will give you a visual of exactly what speech and/or environmental sounds Lexi can and cannot hearing giving her individual type and degree of hearing loss. I know that you are still in the process of identifying that loss and it is SO frustrating. Is Lexi getting speech-language therapy through your school?

I will be finding out what kind of programs our public school system has though as soon as school starts up again. Quote Link to comment Share on other sites More sharing options...
