Successful Treatment of Extremely Severe Obstructive Sleep Apnea with a Dental Appliance

Summary

Background:

A dental appliance for obstructive sleep apnea (OSA) is recommended for patients who cannot adjust to continuous positive airway pressure (CPAP) treatments.

Objectives:

To describe patients with extremely severe OSA who were successfully treated with a dental appliance and to compare their characteristics with the relevant literature to identify clinical features associated with a good outcome.

Methods:

The clinical, management, and outcome data of three patients with an apnea-hypopnea index (AHI) of > 80 who showed clinical improvement following treatment with a dental appliance were collected retrospectively from sleep laboratory reports in Israel over a period of 3 years. 

Results:

The patients included one man and two women, aged 33, 56, and 61 years, respectively. The diagnosis of OSA was based on clinical examination and polysomnography. AHI values at presentation were 83, 81, and 84, respectively. Treatment with a dental appliance (Herbst® or MDSA®) was proposed due to patient noncompliance with CPAP. Follow-up polysomnography with the dental appliance revealed a reduction in the AHI to 1.7, 10.7, and 11, respectively. All patients had supine OSA and a retrognathic mandible, both of which have been found to be associated with a good prognosis for treatment with a dental appliance.

Conclusions:

Dental appliances may be considered an appropriate second-choice option to treat severe OSA in patients who are noncompliant with CPAP. This study helps physicians identify patients with extremely severe OSA who are suitable for dental appliance treatment. Well-designed large-scale studies are needed to reach definitive conclusions.
