Case Study Of Tympanoplasty

Hearing loss continues to linger in the elderly population of today’s society. Yet, the onset of hearing loss can occur at any age and at any point in

Now getting older, I see the effects that hearing loss has had on me. For one, I will admit to having the worst vocabulary skills (thank goodness for a dictionary and thesaurus). For two, I get tongue twisted a lot and do not

Otolaryngologist and neurosurgeon Fred Telischi from the Miller School of medicine states that cochlear implant surgery is part of his daily routine and that side effects from anesthesia although possible are rare.

Since many measures of analysis were found for pre- and post-operatory hearing outcomes (scales and tests), rendering it difficult to compare the results of each author.

This book is a collection of copious case studies of ear keloids in many patients whom I have personally treated in my medical practice. The heart of this book is to review the natural history of ear keloids, how they evolve over time, and how they respond to different treatments.

Since hearing is either blocked or nonexistent, steps for types of hearing aids are available. There is Atresia repair which is a surgical procedure done as early as three years old on some candidates to reopen the canal to the inner ear. Some are ideal candidates while others are to wait and look at other hearing aids. Soft band bone conducting hearing aids that can conduct sound through the skull and deliver some sound to the inner ear through a head band can be introduced to a child as a newborn. The idea to have a child wear a hearing aid as early as six months is to introduce sound and language early. Cochlear implantation or BAHA (Bone Anchored Hearing Appliance) can be done at five years old. There is also the VORP(Vibrating Ossicular Prosthesis), or a Vibrant Soundbridge, which is a device that helps create the middle ear. However, implantation may not be needed if a functioning inner ear is detected. If an inner ear is detected in a MRI and the child shows signs of having a chance to regain hearing, surgery is

While there are many risks involved with cochlear implants, there could also be many benefits. The question that remains is, “Do the benefits of receiving a cochlear implant outweigh the risks?” Although many advances have been made scientifically to improve the effectiveness of cochlear implants, it is also important to examine the opinions of the deaf society, how a deaf person’s communication skills may develop with or without a cochlear implant, and the economic factors

A decade ago there were no technological solutions available to assist a cochlear implant candidate/recipient, who presented with severe to profound hearing loss. A cochlear implant can improve your hearing, but it can never be certain how much. People who have received the surgery often report an improvement in hearing. The ability to hear things is essential to living in any society, even a slight improvement can increase a person’s quality of life.

Medical professionals all over the world have paved the road for further research and technological advances in the hearing impaired spectrum. Implantations, such as the cochlear implant (CI), have given patients with profound sensorineural hearing loss newfound hope for habilitation and rehabilitation services. However, “there exists a small subset of deaf individuals who will not benefit from the CI due to (1) a small or absent cochlea, (2) a small or absent auditory nerve, or (3) injury or scarring of the inner ear or auditory nerve secondary to meningitis, trauma, or tumor” as stated by Kaplan et al. (2015). A treatment option for those who did not meet the candidacy qualifications for a cochlear implant needed to be implemented.

The tympanic membranes play an important role on the hearing process on the patient. In addition TM protects the middle ear against some infections, water, and other bacterial or foreign objects or substances entering to the ear. Some lesions on the conducting system have some negative consequences on the conductive hearing mechanism of the patient, and as result patient can loss hearing.

Conductive hearing loss is from one or more deformity with the outer, inner, or middle ear which impacts sound from transferring to the nerves 5. Conductive hearing loss is often corrected with surgery, drugs, or hearing aids. Sensorineural hearing loss affects the cochlea, which transfers the sounds vibrations to the nerves 5. Although hearing aids are typically used for conductive hearing loss, a profoundly deaf sensorineural patient needs to complete a 6-month trial with them before they are considered ineffective and referred on for further testing for cochlear implant candidacy 5. Sensorineural hearing loss is primarily due to a malfunctioning cochlea so doctors run a hearing test to see how many decibels can be picked up by the cochlea. For pediatric patients to qualify for implants they need to be considered profoundly deaf in both ears. The tone threshold for mild hearing loss is between 21 and 40 dBHL (decibels Hearing Level) and profound hearing loss is greater than 90 dBHL 5. Typically, a pediatric patient looking for cochlear implants will go through a battery of speech-recognition testing while simultaneously undergoing the audiological

While observing the surgery, I learned that the surgeons possess a variety of techniques that can be applied in dealing with a range of otologic findings. One of the more prominent nuances required for implantation was changing the techniques to account

Pure tone audiometry suggested the presence of otosclerosis in the right ear. SRT (50dB for the right ear and 30dB for the left ear) corresponds with the pure tone thresholds. WR scores for the right ear were 96% (85dB) and 100% (70dB) for the left ear, which are consistent with the CHL in the right ear and WNL in the left ear. Typanometry confirmed that finding by revealing a reduced compliance, which indicated less mobility of the tympanic membrane due to increased stiffness. These findings corresponded with the presence of Carhart’s notch at 2000Hz from the audiogram. The absence of OAEs in the right ear also confirmed the conductive component of hearing loss in the right ear due to otosclerosis. The audiology evaluation affirmed that the patient has a decrease in hearing for natural and speech sounds in the right

For Kelly’s surgery doctors decided to permanently implant electrodes into her ear, by attaching an electrode array into the inner ear (cochlea) and a receiver which is placed behind the ear. By doing this each device will be connected to a magnet and an antenna making sound signals channel through her brain. Overall Kelly’s surgery is successful and with speech therapy Kelly is able to talk and hear noises that she was not really able to before.

The success of speech therapy intervention is dependent on successful surgical correction. The authors note that postsurgical complications may include stiffness due to scar tissue decreasing the flexibility of the velum, tethering of the velum, weakness of the velum, and shrinking of the velar tissues. The authors also note the risk of malocclusion as the child grows and the palate continues to grow and develop.
