Objective: Pillar implant (PIT) is a simple, office-based procedure with minimal morbidity that was introduced in 2003 to treat snoring and mild/moderate obstructive sleep apnea/hypopnea syndrome (OSAHS). We studied the: (1) success rate using subjective symptoms and objective polysomnographic improvement; (2) success rate based on BMI, OSAHS severity and Friedman tongue position (FTP); and (3) its value as an adjunctive or revision procedure.

Study Design And Setting: Retrospective review of 125 patients who underwent the PIT for snoring and OSAHS. Patients were grouped: Group I had PIT only (n = 29); Group II received adjunctive nasal procedures (n = 37), Group III received adjunctive oropharyngeal procedures (n = 55); and Group IV had failed previous UPPP (n = 4).

Results: Overall subjective and objective "cure" rates were 88.0% and 34.4%, respectively. Group IIb had the best objective cure rate of 46.7%. Neither AHI nor BMI correlated with outcome measures, whereas FTP did correlate. (FTP I and II had improved success vs FTP III and IV). Ten patients had partial extrusion of the PIT. These were removed and new PIT were carried out at a later date.

Conclusions: Based on a short-term study, the Pillar implant is an effective treatment for snoring and OSAHS in selected patients and can be combined with adjunctive procedures to treat OSAHS.

Implantable cardioverter-defibrillators (ICDs) are recommended to reduce the risk of sudden cardiac death (SCD) in patients with heart failure with reduced ejection fraction (HFrEF). The landmark studies leading to the current guideline recommendations preceded the 4 pillars of guideline-directed medical therapies (GDMTs). Therefore, some have questioned the role of ICDs for primary prevention in current clinical practice.
