Superior semicircular canal dehiscence syndrome. / Buegangsdehiscens.

Superior semicircular canal dehiscence syndrome is a condition with troubling ear symptoms and vertigo caused by a defect in the bone between the inner ear and the middle cranial fossa. The disease is not dangerous, and for many patients it is sufficient to provide a thorough explanation for the symptoms and advice about coping strategies, balance exercises and, if necessary, use of assisted hearing devices. Surgical treatment may be appropriate for patients with severe symptoms.

One-year results: palatal implants for the treatment of obstructive sleep apnea.

OBJECTIVE: To evaluate long-term effectiveness of palatal implants for treatment of mild to moderate obstructive sleep apnea (OSA). STUDY DESIGN: A prospective study of 26 referred patients with a pretreatment apnea-hypopnea index (AHI) of 10 to 30 and a body mass index of < or =30, representing an extended follow-up of a subset of 41 patients enrolled in previous short-term trials. RESULTS: Twenty-one of 26 patients (80.8%) experienced a decrease in AHI. Fifteen of 26 patients (57.7%) had a follow-up AHI <10 at 1 year, whereas 13 patients (50%) had a 50% or greater reduction to an AHI <10 at 1 year. Mean AHI was reduced from 16.5 +/- 4.5 at baseline to 12.5 +/- 10.5 at 3 months (P < 0.014) and to 12.3 +/- 12.7 at 1 year (P < 0.019). CONCLUSIONS: Patients initially responding to palatal implants with improved AHI maintained improvement through long-term follow-up at 1 year.

Palatal implants for the treatment of snoring: long-term results.

OBJECTIVE: To evaluate the safety and long-term effectiveness of a new treatment for snoring using permanent palatal implants. STUDY DESIGN: Prospective study with 35 patients referred to the clinic for the treatment of snoring. The patients were followed for 1 year, and a sleep analysis was performed and repeated at 360 days. During the procedure, 3 braided polyethylene terephthalate implants were placed in the palate of each patient. RESULTS: The average duration for nonnarcotic analgesics was 1.3 days. No adverse events were observed. The mean snoring intensity was reduced from 7.1 at baseline to 4.8 at 1 year (P < 0.001). Bed partner satisfaction rate was very high at 70.6% after 1 year. Six patients (17.8%) experienced a total of 9 partial extrusions. CONCLUSIONS: The palatal implant system is safe, and the effectiveness in treating snoring is comparable to other surgical methods. Advantages are virtually no tissue damage and minimal patient discomfort as a result of one standardized, low-cost procedure. EBM RATING: C-4.

Soft palate implants for the treatment of mild to moderate obstructive sleep apnea.

OBJECTIVE: To evaluate the initial short-term effectiveness of palatal implants in treating patients with mild to moderate obstructive sleep apnea (OSA). Previous published studies have focused on snoring without OSA. STUDY DESIGN: A prospective, nonrandomized study of 25 previously untreated patients with an apnea-hypopnea index (AHI) of 10 to 30 and a body mass index (BMI) of

Consequences of increased rigidity in palatal implants for snoring: a randomized controlled study.

OBJECTIVE: Palatal implants have seen an increased role in the treatment of snoring. In this study, we evaluate the safety and possible treatment effect of adding further stiffness to the palate through the use of a more rigid implant. STUDY DESIGN: Randomized double-blind study of 20 patients with primary snoring. Three polyethylene teralphate implants were placed in the soft palate with the patient under local anesthesia. Ten patients received regular implants (rigidity 1.0) and 10 patients received stiffer implants (rigidity 1.8). The patients and their bed partners were followed for 6 months with questionnaires and office visits. A sleep study was performed preoperatively and at the last follow-up. RESULTS: Four of the 10 patients with stiffer implants had 5 partial extrusions in the observation period. There was a nonsignificant reduction in snoring intensity from 8.1 to 6.1 evaluated by the bed partner on a visual analogue scale in this group. No extrusions were seen in the group with regular implants. This group showed a significant reduction in snoring intensity from 7.7 to 4.7. No other major adverse events were observed. CONCLUSIONS AND SIGNIFICANCE: Rigid implants cause short time extrusions with loss of treatment effect. Regular implants reduce palatal snoring intensity with high patient and bed partner satisfaction. EBM RATING: A-1b.
