Comparison of Functional Expansion Pharyngoplasty with Radiofrequency Volume Reduction of the Soft Palate in Surgery for Sleep-related Breathing Disorders

چکیده
Objective: Many different surgical approaches at the level of the palate for obstructive sleep apnea (OSA) exist. The functional expansion pharyngoplasty (FEP) was first described 2013. The objective of this study is to evaluate the efficiency of FEP in comparison with radiofrequency-tissue volume reduction of the soft palate (radiofrequency uvulopalatopharyngoplasty, RF-UPPP). Methods: 40 patients (group A) underwent surgery at the Cantonal Hospital of Basel-Land Liestal for OSA receiving FEP, tonsillectomy (TE) and nasal surgery if indicated. This cohort was retrospectively matched with 40 previously operated patients undergoing RF-UPPP, TE and nasal surgery if clinically indicated (group B). Respiratory polygraphy was obtained preoperatively and at 3 months postoperatively. Apnea hypopnea index (AHI) was defined as the primary outcome measure. Results: Postoperative AHI significantly improved for groups A and B. However, improvement for Group B was significantly better. Conclusion: FEP showed no significant advantage over RF-UPPP in an operative concept for treatment of OSA.

Sphincter pharyngoplasty as a treatment of velopharyngeal incompetence in young people: a prospective evaluation of effects on sleep structure and sleep respiratory disturbances.
BACKGROUND Sphincter pharyngoplasty (SP) appears to be the more "physiologic" surgical technique to treat velopharyngeal incompetence (VPI). This procedure creates a dynamic sphincter of variable diameter and keeps the flexibility of the soft palate. SP also induces velopharyngeal size reduction, mainly in the transverse diameter, which may cause upper airway (UA) occlusions during sleep. AIM...

The surgical treatment of obstructive sleep apnoea in patients who are non-compliant with continuous positive airway pressure therapy still represents a valid alternative. In recent years, the multilevel approach is becoming more diffuse in routine surgical practice, especially since the introduction of transoral robotic surgery. Barbed reposition pharyngoplasty in multilevel robotic surgery fo...
