RESUMEN
OBJECTIVES: To systematically review long-term (> 5 years) outcomes of ESP surgery for OSA treatment over 17 years. METHODS: Systemic review of MEDLINE, Google Scholar, Cochrane Library and Evidence Based Medicine Reviews to identify publications relevant to OSA and Expansion Pharyngoplasty and its variants. All relevant studies published between January 2007 and June 2023 were included. RESULTS: Twelve studies were included in this systematic review with a combined total of 1373 patients who had the ESP procedure were included. The clinical outcomes included encouraging long-term success rate, reductions in Epworth sleepiness scale, good mean disease alleviation, anatomical structural area and volume improvements, blood pressure reductions, biochemical improvements in acute phase reactants after ESP surgery, reductions in intra-ocular pressures, and post-operative reduction of sympathetic overdrive. CONCLUSIONS: Seventeen years on, the expansion sphincter pharyngoplasty has demonstrated not only increase in anatomical area and volume but significant desired improvements in polysomnographic, clinical and biochemical parameters post-surgery.
RESUMEN
OBJECTIVE: A 15 year review of the outcomes and success rates of the Expansion Sphincter Pharyngoplasty (ESP) in the treatment of patients with obstructive sleep apnea (OSA). METHODS: A systemic review with two independent searches of MEDLINE, Google Scholar, Cochrane Library and Evidence-Based Medicine Reviews to identify publications relevant to OSA and Expansion Pharyngoplasty. All relevant studies published before 31 December 2021 were included. RESULTS: Sixteen studies were included in this strict systematic review with a total of 747 patients who had the ESP procedure were included. The mean age was 41.3 years, mean BMI 28.2, the mean pre-op AHI was 32.3 and post-op AHI was 10.0 (p < 0.05), the mean pre-op ESS was 11.4, had reduced to post-op 5.3 (p < 0.05), and the mean pre-op snore VAS decreased from 8.7 to 2.9 (p < 0.05), with a mean follow-up time of 9.5 months. The overall pooled success rate for all the 747 patients was 80.0%. There were no significant reported complications noted in these studies. CONCLUSION: After 15 years of presence, the expansion sphincter pharyngoplasty has shown to be reliably effective in the management of patients with OSA.
