Sometimes, hearing loss occurs because of damage to the tiny hair cells within the inner ear. Using a cochlear implant device allows deaf patients to bypass the effects of inner ear damage, giving them the ability to hear some form of sound. A cochlear implantation requires drilling a hole behind the ear, through the skull bone, and to the inner ear. Researchers may have found another way to perform this procedure.
Using Robotics for Cochlear Implantation
During a cochlear implantation, the hole is drilled to allow the device access to the inner ear. To improve the drilling procedure, scientists at the University of Bern turned to robotics. They developed a high-precision surgical robot to create the entryway for the cochlear device. Their hope is that it provides better hearing outcomes.
The surgical robot would make the hole about 2.5mm in diameter. In order to perform a task of such magnitude, the robot has the do the surgery by itself and without any hands-on interaction or visual from a surgeon. This obviously presents concerns. Surgeons need to be able to track the drill’s progress to make sure in is on track and just in case there is an error.
The researchers built the robot with interlocking safety components. This allows the drill to avoid damaging key areas like the nerves and inner ears.
Prof Weber of the University of Bern, explains: “The robot relies on a number of sensors which are a high-accuracy, optical tracking system, a sensor for resistance that can “feel” the texture of the bone while drilling, and a radar-like nerve stimulation probe that sends small electric pulses into the bone from which the robot can compute whether or not it is on the preplanned track.”
This may be the next major development in cochlear implantation. It has proven effective for one patient and hopefully, it will prove helpful for future patients.
Endoscopic Sinus Surgery: Good News for People With Chronic Sinusitis
Endoscopic sinus surgery is a minimally invasive procedure that offers new hope for sufferers of chronic sinusitis. Advancements are quickly being made when it comes to surgery, and endoscopic surgery, in particular, now boasts a number of benefits. In fact, the changes made in how sinus surgery is performed may allow many people who have chronic sinusitis find relief. The changes have certainly made this an exciting treatment option and the least invasive surgical procedure for the condition now available.
One of the benefits to this new method is it requires much less time to perform. Because of this, the amount of time a patient needs to be under anesthesia is also reduced. Moreover, the surgery can be mapped out prior to the operation, which also helps reduce time. The cumulative effect of these time-savings means there is no need to stay overnight at the hospital. In fact, patients are normally sent home a few hours post-surgery. Recovery is also very quick, adding to the overall appeal, and people are well enough to return to work within a few days.
The real breakthrough, however, is with the incision, or, more precisely, the lack of incision. Previously, surgery for this condition required a long incision on the face with the concurrent chance of scarring. The new procedure is done through the nasal passage so, cosmetically, the patient is unscathed.
Not only are surgery times shortened, and appearances greatly improved, but the accuracy is exceptional as well. Using the endoscopic probe means that a precise view of nasal passages and problem areas are readily available. ENT’s can treat the problem in a manner so meticulous that healthy tissue remains intact and untouched. This provides better overall results, making the treatment even more effective. One last benefit is that the pinpoint nature of endoscopic sinus surgery results in much less bruising and swelling, too. Thus, after the surgery, the patient will look as good as they now feel.
Acupuncture After Tonsillectomy: A Safe Alternative to Treat Pain in Children After Tonsillectomy
For thousands, having their tonsils removed is one event that can disrupt the pleasant carefree spirit of childhood, albeit temporarily. It is a very common procedure, though not one that is embraced by both parents and children alike as it can bring about great discomfort and pain. While it does bring relief in the long run, recovery time after surgery can be unpleasant. Prescribing codeine used to be the standard to combat pain and discomfort. As of early last year, the FDA banned codeine for this purpose. Other pain-relieving alternatives have to be sought, and acupuncture after tonsillectomy may be a viable option for children.
It was ascertained that codeine could cause severe complications when used for pain management after a tonsillectomy in children, and hence the FDA ban. Physicians have been trying to find an adequate replacement to ease postsurgical pain in children. One ENT specialist discovered that acupuncture is a safe, easy, and affordable solution. A trial including 31 children of varying ages found that acupuncture relieved symptoms almost immediately. Upon following up with parents, it was also noted that the treatment lasted more than two days. The use of an alternative drug-free therapy over a narcotic has its appeal, especially when it comes to younger children.
In the past, over-the-counter pain relieving medications, such as ibuprofen, have been used to ease post-surgery pain in children but with little success as they can cause severe complications in very young patients. Finding a safe alternative that is just as effective is something many in the ENT field are excited about. Similar studies are underway to help determine if acupuncture would have the same results in children undergoing other types of surgery as well. In the meantime, physicians will continue to take advantage of these findings and employ them when it comes to their smallest patients and mindfully recommend acupuncture after tonsillectomy to parents.
In a journal for ear, nose, and throat doctors, new guidelines are about to be published for performing tonsillectomies on minors. The guidelines will include recommendations on how to care for patients in pre-op, intra-op, and post-op situations, and also include research on the complications that arise when different doctors approach this same surgery in different ways.
This is one of the most frequently performed surgeries in the United States – in fact, over 500,000 are performed each year, and that’s just among children aged 15 or younger.
What is a tonsillectomy? By definition it involves the removal of the entire tonsil (capsule included), by means of the separation of the tonsil from the muscular wall – this area is known as the peritonsillar space. In some cases the tonsillectomy will include an adenoidectomy – this is more common when the reason for the surgery is a problem with breathing during sleep.
These published guidelines are going to be very important resource for the doctors who perform approximately 530,000 of these surgeries each year. It is hoped this will result in an easier process for surgeons, allowing them to make wise decisions which will render favorable surgical outcomes for the many children afflicted by tonsil problems.
One of the main things the guidelines will accomplish is to make it easier for practitioners to better determine when a tonsillectomy is the best way to proceed. They are also intended to help healthcare staff to manage the care of children undergoing a tonsillectomy more effectively.
The guidelines also encourage proper counseling for families of children undergoing such medical procedures, as they can be frightening especially for very young children. It will also cut back on the discrepancies between different practitioners who are treating patients with similar problems. It will also provide caregivers with alternative treatments for situations that do not require surgery.
