Palatal Implants for Persistent Snoring and Mild Obstructive Sleep Apnea After Laser-Assisted Uvulopalatoplasty

  • 1Department of Otorhinolaryngology-Head and Neck Surgery, Korea University College of Medicine, Seoul, Korea.


Laser-assisted uvulopalatoplasty (LAUP) was widely performed in 1990s as a surgical therapeutic procedure to improve snoring or mild obstructive sleep apnea (OSA). However, LAUP is not currently recommended as a treatment for OSA because the evidence for its efficacy is insufficient. Little is known about alternative minimally invasive surgery in patients who refuse continuous positive airway pressure or oral appliance after failed LAUP. We present a case of successful surgical treatment of persistent snoring and mild OSA with palatal implants after LAUP. This case suggests that palatal implants may be offered as an alternative surgical procedure for selective patients with persistent or recurrent snoring or mild OSA after LAUP.

  • Fig. 1 Preoperative findings in the oral cavity and oropharynx. (A) The uvula was not observed as a result of a previous palatal surgery and the Friedman tongue position was presumed as grade 2. (B) The tonsils were hidden within the pillars.

  • Fig. 2 Preoperative and postoperative hypnogram focused on respiratory parameters. Apnea-hypopnea index (from 7.6 to 1.3 events/hour) and snoring (from 51.3% to 16.8%) were clearly improved after the palatal implant procedure.
