Effect of Treatment of Obstructive Sleep Apnea by Uvulopalatoplasty on Seizure Outcomes: A Case Report.

It is estimated that one-third of the people with refractory epilepsy suffer from obstructive sleep apnea (OSA). In a patient presenting with OSA symptoms and epilepsy, removing a portion of the soft palate (uvulopalatoplasty) can be considered the treatment of choice for eliminating the OSA and decreasing the seizures. Here, we report the results of our surgical approach by which the patient's problems completely resolved, and we observed no symptoms of OSA or epilepsy after the surgery.

Rehabilitation of an Auricular Defect Using Surgical Stent.

Reconstruction of a facial defect is a complex modality either surgically or prosthetically, depending on the site, size, etiology, severity, age, and the patient's expectation. The loss of an auricle, in the presence of an auditory canal, affects hearing, because the auricle gathers sound and directs it into the canal. The auricle acts as a resonator to slightly amplify lower frequency sounds and helps to localize sounds, especially in conjunction with the other ear.
