Remotely Controlled Mandibular Positioning During Drug-Induced Sleep Endoscopy Toward Mandibular Advancement Device Therapy: Feasibility and Protocol

Although it seems to be an exhausted subject at first glance, the therapeutic approach in obstructive sleep apnea syndrome (O.S.A.S.) is still an open subject. The continuous positive airway pressure (C.P.A.P.) represents the gold standard of therapy in O.S.A.S. However, this therapeutic process with C.P.A.P. has a low rate of compliancy, over 50% of patients quit in the first year of use. Implicitly, surgical solutions or mandibular advancement devices remain an alternative for many of these patients. High costs, complexity and risks associated with surgery have led to the identification of more accurate methods for topographic and functional diagnosis in O.S.A.S. Drug-induced sleep endoscopy (D.I.S.E.) with target-controlled infusion (T.C.I.) using propofol in the management of patients with obstructive sleep apnea is a relatively recently introduced method in Romania. The present paper describes our experience with D.I.S.E for selected patients, who have undergone surgery on the upper airway for O.S.A.S. The D.I.S.E method has led to the modification of the initial surgical plan in over 60% of patients with multi-level obstruction. Under these conditions, the surgical success rate in patients of the study increased to 80% at 6 months. Considering the specific endowment of each tertiary sleep center, the presence or absence of an operator block and the anesthetist�s experience with target-controlled (T.C.I.) infusion using propofol, more extensive and multicenter studies are needed for standardization of D.I.S.E.

Abstract Introduction In the literature, evidence is lacking on the predictive value of drug-induced sleep endoscopy (DISE) for oral appliance treatment (OAT). Objectives The aim of the present study is to evaluate whether DISE with concomitant mandibular advancement maneuver can predict failure of OAT. Methods An observational retrospective study including patients diagnosed with obstructive sleep apnea (OSA) who previously received OAT. Results of DISE were analyzed in a group with documented OAT failure (apnea-hypopnea index [AHI] > 10 events/hour or < 50% reduction) and a group with OAT benefit (AHI <10 events/hour or > 50% reduction). The upper airway was assessed using the velum, oropharynx, tongue base, epiglottis (VOTE) classification. Additionally, a mandibular advancement maneuver, manually protruding the mandible by performing a jaw thrust, was performed to mimic the effect of OAT. Results The present study included 50 patients with OAT failure and 20 patients with OAT benefit. A subgroup analysis of patients with OAT failure and an AHI < 30 events/hour included 26 patients. In the OAT failure group, 74% had a negative jaw thrust maneuver. In the subgroup with an AHI < 30 events/hour, 76.9% had a negative jaw thrust maneuver. In the OAT benefit group, 25% had a negative jaw thrust maneuver (p < 0.001). Conclusions A negative jaw thrust maneuver during DISE can be a valuable predictor for OAT failure, independent of AHI. Drug-induced sleep endoscopy should be considered as a diagnostic evaluation tool before starting OAT.
