The Austin Ear Nose & Throat (ENT) clinic is located on Research Blvd in Ascension Seton Complex…read more You might ask why am I seeing an ENT? I thought my mouth pain had been eliminated. Apparently, I had two sources of mouth pain - 1) lower portion of my mouth - eliminated via a root canal and 2) now, the upper part of my mouth. The upper pain has been a little more difficult to diagnose. I went to my dentist, who was not able to pinpoint any tooth pain. Thus, today I ended up at Austin Ear Nose & Throat clinic. First my ears were evaluated by listening to high and low sounds while pressing a button when I heard the sounds. In addition, an overall evaluation of my ears was completed. No water in my ears, no wax build up. That was good to hear. In addition, Dr. Boerner did a live scan of the my sinus and found no infection. It was quite interesting viewing the inside of my nose via a monitor. Dr. Boerner has a pleasant demeanor and super helpful in explaining medical details. Before my office visit I was sent a link to fill out my medical history and pay my co-pay. The only paper work iI needed to complete in-office was some consent forms. Thus, a pretty straightforward process. Diagnosis: Allergy treatment, CT imaging and 4 week follow-up.

It was my great fortune to choose Dr. Daniel Slaughter as my sleep apnea doctor when my former…read moredoctor retired. Dr. Slaughter has a double board certification in both Otolaryngology and Sleep Medicine, and has over 30 years of experience. He trains other ENT doctors to use his balloon technique. If you have to have deviated septum or sinus surgery, or need help with sleep apnea, I highly recommend this physician for your treatment. He helped develop a minimally invasive technique called balloon sinuplasty. I have heard many horror stories regarding recovery from people who experienced deviated septum surgery in other ENT doctor's offices. I experienced nothing but positivity yesterday. When I arrived for surgery, from the front desk staff who greeted me and checked me in, to every single person I encountered, I felt at peace. The nurses are exceptional, especially Karen, who checked on me in the recovery room, and the nurse who stayed with me after surgery (I don't remember her name). When Karen had me prepped for surgery and walked me into the surgery room, I saw the doctor, the anesthesiologist, and at least 3 nurses, standing in a simi circle around the chair, all smiling at me, as if they were the welcoming committee! It gave me such a feeling of peace, and I knew they were going to take good care of me. Every single encounter was first class and professional. My recovery so far has been excellent, with very little bleeding, no stints in my nostrils, and only mild discomfort. I am thrilled to share my experience with everyone I can so no one has to tell another horror story about their deviated septum experience. Nancy L

She did a head CT that revealed a deviated septum, and referred me to Dr. Wassmuth. I was quite impressed by the kindness, courtesy, and professionalism when I first visited the office of Capitol Otolaryngology. Dr. Wassmuth examined my nose and suggested balloon sinuplasty with turbinate reduction. After much trepidation, I scheduled the surgery, which is done in-office. The process of fixing my nose didn't take all that long. The anesthesiologist, Dr. Jack Carsner, was excellent, as were all those I met in the operating room. The procedure apparently went off without a hitch, and my husband drove me home where I rested the remainder of the day. Within a day or so I was feeling much better. I am still considered to be recovering after a week, but have already experienced noticeable improvements in my breathing. My husband says my snoring was virtually gone within a day after the procedure. I've had a variety of seemingly-minor health concerns, that when put together, have led to other problems. Snoring, dry mouth, dental issues, and poor sleep quality turned out to have (at least in part) had a common root cause in breathing problems. Hopefully all will improve or resolve before very long. If you have any kind of breathing problems, including snoring and symptoms like dry mouth when you awaken, you may benefit from a visit to Dr. Wassmuth. I highly recommend his medical practice.

In March 2023, Dr. Slaughter performed the following surgeries to resolve my issues: balloon sinuplasty, septoplasty, turbinate reduction, and rhinoplasty. After surgery, my issues were still present and I had more difficulty breathing. At my post-op appointment, Dr. Slaughter's PA documented a newly acquired nasal-valve collapse and told me to wear nasal strips (which I did not have to wear prior to surgery). After almost a year of dealing with the collapse, Dr. Slaughter performed a VivAer procedure. Although there was some improvement, I continued to have breathing and structural concerns. At my February 2024 follow-up appointment, my concerns were minimized and I was, again, told to use nasal strips. I left that appointment assuming there was nothing more that could be done and I was permanently stuck with a collapsed nasal cavity and very minimal structural support. I was also disappointed by the communication and follow-up regarding the rhinoplasty portion of my surgery. I did not feel that the specific rhinoplasty plan, including what existing structural support might be removed or replaced, was adequately discussed with me. I later sought independent ENT evaluations because my sinus headaches became too intense to ignore. Those evaluations documented reduced tip support, mobile anterior cartilage that is not secured to the nasal spine (seen in photos below), marked narrowing of the left internal and external nasal valves, and a need for further functional reconstruction with grafting. Both of these ENT's stated the graft removal is a large part of the reason for the collapse. I now have to pay $13k out of pocket to reconstruct my nose with my own rib cartilage. Due to the cost of the reconstruction, I requested a refund of the $7k I paid for surgeries with Dr. Slaughter. I requested the reimbursement via his office manager after she replied to my Yelp review (which was removed from this page) stating she was willing to discuss my issues. I thought they would be amenable to hearing my concerns but, instead of treating me like a patient with a financial burden caused by a failed surgery at his office, Dr. Slaughter had his insurance company send me a letter stating that they will not reimburse me (see photo). They issued this letter without any information regarding what the two other ENT's found when they examined me. After receiving the letter and reading the word "settlement," I checked the public records. Dr. Slaughter currently has a malpractice case open in Travis County (as of September 2026). For patients considering complex nasal surgery, revision rhinoplasty, grafting, or combined functional and cosmetic procedures, I encourage getting more than one specialist opinion, asking for a clear written surgical plan, and discussing exactly what support structures or grafts may be preserved, removed, or replaced. I also highly encourage people to seek ENT services elsewhere, unless you want to be told you need a balloon sinuplasty on all of your sinuses, a septoplasty, and turbinate reduction.
