Carol D Posted January 17, 2023 Report Share Posted January 17, 2023 in order to determine if my array is positioned correctly I have decided to have CT scan. Have any of you done this??

HearPeers Heroes Mary Beth Posted January 17, 2023 HearPeers Heroes Report Share Posted January 17, 2023 I have had a CT scan to check the electrode array positions Quote Link to comment https://forum.hearpeers.com/topic/14759-ct-scan-for-array-position/#findComment-64597 Share on other sites More sharing options...
Members Tim Posted January 18, 2023 Members Report Share Posted January 18, 2023 Interesting. Does it require that the clinic have OtoPlan to make use of a CT scan after implantation? Did you have to ask the clinic to place the order or did they suggest it? Does it it help the Audi in activation and mapping to get a running headstart on the pitch placement? I don't want to be a pain for my Audi but if it helps, I can ask as long as I have wait another 9 days.

Jimit Posted January 18, 2023 Report Share Posted January 18, 2023 I too have a CT scan after surgery but it was included in standard procedure and I didn't explicitly ask them to do it.

AlanJ Posted January 18, 2023 Report Share Posted January 18, 2023 If Otoplan is used ,is a CT scan included ? Quote Link to comment https://forum.hearpeers.com/topic/14759-ct-scan-for-array-position/#findComment-64632 Share on other sites More sharing options...
HearPeers Heroes Mary Beth Posted January 18, 2023 HearPeers Heroes Report Share Posted January 18, 2023 @AlanJ OTOPLAN uses both a pre operative CT scan to determine and view how various electrode arrays will fit in our unique cochleas and a post operative CT scan to recommend frequency assignment to each electrode based on where the actual electrode sits in our cochlea. Surgeons can opt to use OTOPLAN both before and after surgery or just before or just after or not at all.

AlanJ Posted January 18, 2023 Report Share Posted January 18, 2023 @Mary Beth Thanks.. I`m guessing it is something that needs to be requested. Quote Link to comment https://forum.hearpeers.com/topic/14759-ct-scan-for-array-position/#findComment-64637 Share on other sites More sharing options...
HearPeers Heroes Mary Beth Posted January 18, 2023 HearPeers Heroes Report Share Posted January 18, 2023 @AlanJ Some surgeons use it routinely. We can always discuss having it used if we wish.

Lauren Posted March 24, 2023 Report Share Posted March 24, 2023 At my last mapping a few weeks back I explained in my own words (badly) Otoplan and my desire to have the CT scan for the purpose of maybe getting an ideal map. No expectations nor promises made, and still none, but my Audiologist notified me today that the surgeon’s office will be scheduling me at some point for a CT scan so fingers (and toes) remain crossed.

HearPeers Heroes Mary Beth Posted March 25, 2023 HearPeers Heroes Report Share Posted March 25, 2023 @Lauren Med-El US is offering something called OTOPLAN on demand. Our surgeons can request it and send in our CT scan prior to surgery for electrode array selection information based on our individual cochleas and they can also send post operative CT scan to be reviewed for Anatomy Based Fitting. Anatomy Based Fitting uses the post operative CT images to determine the location of each electrode in our cochleas and then frequency ranges are determined for each electrode instead of using the default frequencies. Keep us posted. https://hearlife.medel.com/en-us/local/us-pages/otoplan-on-demand Med-El will do this and then our clinical audiologist just needs to select Anatomy Based Fitting for the frequency ranges to be used in our programs. ”With our new anatomy-based fitting tools, you can easily fine-tune the frequency map to be closer to the natural map for each individual cochlea. By combining detailed imaging data from OTOPLAN with MAESTRO 9.0, you can now quickly assign center frequencies based on the actual anatomical location of each electrode contact.” Lauren 1 Quote Link to comment https://forum.hearpeers.com/topic/14759-ct-scan-for-array-position/#findComment-66596 Share on other sites More sharing options...
John F Posted March 25, 2023 Report Share Posted March 25, 2023 Curious at the results whether a map comes out better with Otoplan in place, or if it basically doesn’t change much from the standard manual adjustments. 🤔 edit: MedEl & my surgeon are working with this for my left ear that will be implanted this coming week mainly to avoid the silliness of the first surgery. Was not aware of its uses post-op so will be interesting.

HearPeers Heroes Mary Beth Posted March 25, 2023 HearPeers Heroes Report Share Posted March 25, 2023 @John F Wishing you the best! The post op use of OTOPLAN requires a post operative CT image. A few members of HearPeers have participated in research studies and have had both a pre op and post op CT and have had their surgeon determine the best electrode array via OTOPLAN from the pre op CT and have been activated with anatomy based fitting frequency ranges assigned instead of default frequency assignments via OTOPLAN from the post op CT. @Tim has shared his pre op OTOPLAN experience @Lauren has shared she is going to have a post op CT @John R has shared his experience with OTOPLAN both pre op and prior to activation I have not found a study yet that has published established CI users trying OTOPLAN’s anatomy based fitting AFTER adjusting to the default frequencies yet. But using imaging to make changes to active electrodes or reassign the frequencies of electrodes is underway at several university research centers and some of us have experienced and are now participating in those studies. I have participated in Vanderbilt’s image guided CI MAPping. @Roy is participating in UNC’s image guided pitch study led by Meg Dillon @Dennis is participating in U of Cal SF pitch study led by Charles Limb and I am sure I am forgetting other members who have or are participating in various image based individualization approaches to CI MAPping Keep us posted on your experience. Will they take images of both sides and also use anatomy based fitting to adjust the frequency assignment to electrodes on your first side?

Ricky W Posted March 26, 2023 Report Share Posted March 26, 2023 I'm also in the study at UNC Chapel Hill led by Med Dillon. I have been participating for 3 months now.

John F Posted April 1, 2023 Report Share Posted April 1, 2023 Update: Had my surgery Thursday. Oh so many things the surgeon did that makes zero sense and leads me to believe the Otoplan was not actually utilized, it’s infuriating but will be contacting MedEl soon as my body isn’t dizzy.

Lauren Posted May 3, 2023 Report Share Posted May 3, 2023 Got my CT imaging Friday (April 28) and today my audiologist made sure my surgeon’s office sent her the CT imaging as apparently it has to be a certain file type for Med-El to upload. Then I got a message that she had personally sent it to Med-El. Back to waiting now as my audiologist is interested in learning this process as it’s entirely new (to her) so we are both unsure as to turnaround. One thing I appreciate about Med-El is how on top of things everyone is so I don’t imagine it’ll be too long of a wait. Curious to find out if this makes any difference at all.

HearPeers Heroes Mary Beth Posted May 3, 2023 HearPeers Heroes Report Share Posted May 3, 2023 @Lauren I am curious about your experience with anatomy based fitting (ABF) as well. I have not read many reports from users who received this after already adjusting to their MAPs. @Roy has shared his experience with UNC’s approach after activation.

Lauren Posted May 26, 2023 Report Share Posted May 26, 2023 Oddly enough I’m still waiting on whatever Med-El comes up with. I checked with my audiologist and she hasn’t gotten anything yet. Said it sounded like it would be a quick process but maybe not lol.

HearPeers Heroes Mary Beth Posted May 26, 2023 HearPeers Heroes Report Share Posted May 26, 2023 @Lauren I have not read anything about how long it takes to have your CT scan put through OTOPLAN for ABF frequency allocation. Nor how Med-El US communicates that it has been completed. I did read that our audiologist just needs to check a box to use ABF in the software for our MAP. Keep us posted.
