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.

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.

OBJECTIVE: Does nasal surgery affect multilevel surgical success outcome. METHODS: Prospective eight country nonrandomized trial of 735 obstructive sleep apnea (OSA) patients, who had multilevel palate and/or tongue surgery, divided into two groups, with or without nose surgery. RESULTS: There were 575 patients in nose group, 160 patients in no nose group. The mean age for nose group 44.6 ± 11.4, no nose group 44.2 ± 11.8. Mean preoperative BMI for nose group 27.5 ± 3.6, no nose group 27.5 ± 4.1, mean postoperative BMI nose group 26.3 ± 3.7, no nose group 27.1 ± 3.8 (P = .006). Mean preoperative AHI nose group 32.7 ± 19.4, no nose group 34.3 ± 25.0 (P = .377); and mean postoperative AHI nose group 13.5 ± 10.2, no nose group 17.1 ± 16.0 (P = .001). Mean preoperative ESS nose group was 11.3 ± 4.7, no nose group was 10.4 ± 5.4 (P = .051); and mean postoperative ESS nose group was 5.3 ± 3.2, no nose group was 6.7 ± 2.8 (P = .001). The nose group had higher percentage change (adjusted for age, gender, BMI) in AHI (33.7%, 95% CI 14% to 53.5%) compared to the no nose group (P = .001); the nose group also had more percentage change in ESS (37%, 95% CI 23.6% to 50.3%) compared to the no nose group (P < .001). Change in BMI did not affect AHI nor ESS change (Cohen effect 0.03 and 0.14, respectively). AHI change in both groups were also statistically significant in the mild OSA (P = .008) and the severe OSA (P = .01). Success rate of surgery for the nose group 68.2%, while the no nose group 55.0% (P = .002). CONCLUSION: Combining nose surgery in multilevel surgery improves surgical success. LEVEL OF EVIDENCE: IIC.

OBJECTIVES/HYPOTHESIS: To investigate long-term complications of newer reconstructive palate surgery techniques. STUDY DESIGN: Retrospective case-series analysis. METHODS: Retrospective six-country clinical study of OSA patients who had nose and palate surgery. RESULTS: There were 217 patients, mean age = 43.9 ± 12.5 years, mean body mass index = 25.9 ± 4.7, mean preoperative apnea-hypopnea index [AHI] = 30.5 ± 19.1, follow-up 41.3 months. A total of 217 palatal procedures were performed, including 50 expansion sphincter pharyngoplasties (ESP), 34 functional expansion pharyngoplasties (FEP), 40 barbed reposition pharyngoplasties (BRP), 64 modified uvulopalatopharyngoplasties (mUPPP), 11 uvulopalatal flap procedures (UPF), nine suspension pharyngoplasties (SP), eight relocation pharyngoplasties (RP), and one z-pharyngoplasty (ZPP). Complications included were constant and/or felt twice per week; dry throat (7.8%), throat lump feeling (11.5%), throat phlegm (10.1%), throat scar feeling (3.7%), and difficulty swallowing (0.5%). Of the 17 patients who had a dry throat complaint, two were constant (one SP, one RP), 15 were occasional (10 mUPPP, three SP, two BRP). Of the 25 patients with the throat lump feeling, four were constant (three RP, one ZPP), 21 were occasional (10 mUPPP, five SP, five UPF, one BRP). Of the 22 patients with the throat phlegm feeling, four were constant (two SP, two RP), 18 were occasional (10 mUPPP, four BRP, two FEP, two SP). Of the eight patients with throat scar feeling, eight were occasional (four SP, two mUPPP, one FEP, one RP), none were constant. One patient had difficulty swallowing (RP procedure). There was no velopharyngeal incompetence, taste disturbance, nor voice change. Highest symptom complaints were mUPPP, SP, and RP, whereas the lowest symptom complaint was ESP. CONCLUSIONS: Newer palatal techniques have shown to have less long-term complications compared to the older ablative techniques. LEVEL OF EVIDENCE: 4 Laryngoscope, 130:2281-2284, 2020.

OBJECTIVES/HYPOTHESIS: Our objective was to determine whether drug-induced sleep apnea (DISE) affects the successfulness of the surgical outcome. STUDY DESIGN: Prospective, seven-country, nonrandomized trial. METHODS: There were 326 consecutive obstructive sleep apnea (OSA) patients who had nose, palate, and/or tongue surgery included in the study. DISE was performed in only one group. RESULTS: There were 170 patients in the DISE group and 156 patients in no-DISE group. The mean preoperative body mass index (BMI) for the DISE group was 27.6 ± 4.6, whereas in the no-DISE group it was 28.1 ± 3.9 (P = .23). The mean preoperative systolic blood pressure (SBP) for the DISE group was 130.4 ± 16.7, whereas in the no-DISE group it was 142.9 ± 15.5 (P < .001). The mean preoperative diastolic blood pressure (DBP) for the DISE group was 81.4 ± 9.7, whereas in the no-DISE group it was 89.1 ± 9.7 (P < .001). The mean preoperative apnea-hypopnea index (AHI) for the DISE group was 32.6 ± 18.8, whereas in the no-DISE group it was 33.7 ± 19.6 (P = .61). The mean postoperative AHI for the DISE group was 15.9 ± 12.6, whereas in the no-DISE group it was 13.2 ± 8.8 (P = .023). The age-, gender-, BMI-adjusted percentage change in AHI for the DISE group was -48.4 ± 31.9, whereas in the no-DISE group it was -59.8 ± 18.6 (P < .001). The age-, gender-, and BMI-adjusted success rate for the DISE group was 66.5%, whereas in the no-DISE group it was 80.8% (P = .004). The age-, gender-, and BMI-adjusted change in SBP for the DISE group was -6.1 ± 8.6, whereas in the no-DISE group it was -13.3 ± 11.1 (P < .001). The age-, gender-, and BMI-adjusted change in DBP in the DISE group was -5.2 ± 12.1, whereas in the no-DISE group it was -12.4 ± 11.7 (P < .001). The mean age- and gender-adjusted change in BMI for the DISE group was -4.6 ± 12.9, whereas in the no-DISE group it was -6.3 ± 18.5 (P = .34). The Cohen effect of BMI on the overall AHI, lowest oxygen saturation, and blood pressure changes was 0.08. CONCLUSIONS: DISE may not significantly affect surgical success in OSA.

OBJECTIVE: To evaluate multilevel palate and tongue base surgery as a method of treatment of obstructive sleep apnea by comparing the pre- and postoperative apnea-hypopnea index. METHODS: We conducted a systematic review. MEDLINE and Embase databases were searched in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for conducting systematic reviews. Two authors screened all articles and performed methodological quality assessment. Relevant articles where reviewed in detail. Standard inclusion criteria were applied for article selection. Relevant data were extracted and summarized, a difference of means random-effects model was performed. Our primary outcome measure was change in apnea-hypopnea index pre-/postsurgical treatment. RESULTS: Of 1,172 studies identified from January 2006 to March 2017, 46 studies met inclusion criteria and were included in the systematic review. This included 11 surgical subgroups and 1,806 patients. Methodological quality and risk of bias assessments were completed. There was strong male predominance 86.8 (standard deviation [SD] = 10.3%), and the average age was 46.8 (SD = 4.0) years. All studies included overweight to obese patients (average body mass index = 29.1 [SD = 3.5]). The average preoperative apnea-hypopnea index was 39.0 (SD = 15.4), and the average postoperative apnea-hypopnea index decreased to 18.3 (SD = 7.5). Meta-analysis data yielded a decrease in apnea-hypopnea index of -23.67 with a 95% confidence interval of -27.27 to -20.06. CONCLUSIONS: Non-maxillomandibular advancement, multilevel surgical procedures for obstructive sleep apnea demonstrate significant improvements in reduction of apnea-hypopnea index following surgery in addition to improvement in many other sleep-specific outcomes. Future research should include larger, higher-level studies that compare surgical treatments and identify factors associated with outcomes. LEVEL OF EVIDENCE: NA Laryngoscope, 129:1712-1721, 2019.

BACKGROUND AND OBJECTIVE: The aim of this study was to demonstrate the long-term effectiveness of Expansion Sphincter Pharyngoplasty (ESP) as a standalone surgical treatment of obstructive sleep apnea-hypopnea syndrome (OSAHS) patients through a prospective multi-center study. MATERIAL AND METHODS: A prospective non-comparative multicenter study of patients suffering from OSHAS selected after drug-induced sleep endoscopy, with ESP as standing alone procedure was performed. Inclusion criteria were lateral collapse on oropharynx and preoperative AHI between 5 and 70. Minimum follow-up was >12 months. Outcome measures were Epworth sleepiness scale (ESS), AHI, success rate and CPAP need after surgery. RESULTS: A total of 75 ESP were performed. Mean patient age was 46.7 ± 10.5 years. Mean pre-operative and post-operative AHI was 22.1 ± 12.2 and 8.6 ± 6.7, respectively (p < .001). Mean pre-operative and post-operative ESS score was 11.5 ± 4.7 and 4.6 ± 6.6, respectively (p < .001). AHI <5 was obtained in 25 patients (33.3%), and CPAP was not further needed after surgery in a total of 62 patients (82.6%). CONCLUSIONS AND SIGNIFICANCE: In this prospective multi-center study, patients undergoing ESP standing alone for the treatment of OSAHS have a reasonable expectation for success with minimal morbidity.

OBJECTIVES/HYPOTHESIS: To evaluate a possible regrowth of lingual tonsil lymphatic tissue in patients submitted to lingual tonsil resection with transoral robotic surgery (TORS). STUDY DESIGN: Retrospective Study. METHODS: Medical records of patients surgically treated by means of TORS to remove excessive lymphatic tissue of the lingual tonsil were retrospectively reviewed. Postoperative endoscopic data after long-term follow-up were analyzed to investigate possible lymphatic tissue regrowth. Preoperative and postoperative lingual tonsil lymphatic tissue were classified according to the standardized Friedman's grading scale ranging from 0 to 4. RESULTS: Sixty-eight patients (41 male and 27 female; mean age = 51.3 years) were considered suitable for the study analysis. Clinical regrowth was observed in six (8.8%) patients: four (5.9%) and two (2.9%) patients with grade 2 and 3 lymphatic hypertrophy, respectively. No correlation between the grade of regrowth, the time interval from surgery, and the volume of lymphatic tissue removed was found. CONCLUSIONS: The lymphatic tissue regrowth after TORS resection appears to be very low. LEVEL OF EVIDENCE: 4 Laryngoscope, 129:2652-2657, 2019.

OBJECTIVES/HYPOTHESIS: To evaluate if upper airway surgery reduces blood pressure in patients with obstructive sleep apnea (OSA). STUDY DESIGN: Prospective series. METHODS: A prospective series of 112 consecutive OSA patients with hypertension (HTN). All patients were > 18 years old, respiratory disturbance index >5, all levels of apnea-hypopnea index (AHI), with a history of HTN treated with medication for at least 6 months. Surgical procedures included septoplasty, turbinate reduction, palate surgery, and tongue base reduction. RESULTS: There were 92 men and 20 women, with a mean age of 48.6 years, mean body mass index (BMI) was 27.5 (range, 19.7-34.7). Mean follow-up was 16.1 months. The mean preoperative AHI was 32.6 (range, 1.2-104), with the mean lowest oxygen saturation (LSAT) of 79.9% (range, 52%-93%). The mean adjusted preoperative and postoperative systolic blood pressure (SBP) was reduced from 146 ± 15.3 mm Hg to 122 ± 12.5 mm Hg (P < .001), and diastolic blood pressure (DBP) was reduced from 91 ± 10.2 mm Hg to 76 ± 7.8 mm Hg (P < .001). There was a decrease in overall BMI from 27.5 ± 3.6 to 25.5 ± 3.0 (P < .001); however, based on multivariate analysis, the reduction in SBP and DBP was not affected by this BMI reduction. Fifty-eight patients (51.8%) did not require their antihypertensive after surgery. There was poor correlation noted between HTN with AHI, LSAT, and oxygen duration <90%. CONCLUSIONS: Upper airway surgery does reduce SBP and DBP in patients with OSA. LEVEL OF EVIDENCE: 4. Laryngoscope, 128:523-527, 2018.

To evaluate the success rates of combined Expansion Sphincter Pharyngoplasty and the Anterior Palatoplasty in the treatment of OSA. A two center prospective series of 73 patients with OSA. All patients were >18 years old, retro-palatal obstruction, concentric velo-pharyngeal collapse, BMI < 33, Friedman clinical stage II, with all grades of AHI. The procedure involved the anterior palatoplasty, tonsillectomy and expansion sphincter pharyngoplasty with or without nasal surgery. There were 68 men and 5 women, the mean age was 46.8 years old (range of 25-67 years), mean BMI was 25.5 (range of 20.3-31.2). All patients had pre-operative and post-operative PSG. The AHI improved in all patients, mean AHI improved from 26.3 ± 17.7 to 12.6 ± 5.8 (p < 0.001). There were 20 mild OSA, 33 moderate OSA and 20 severe OSA patients. Twenty-three patients had pre-operative DISE, and 61 patients had nose/palate surgery, while only 12 had palate surgery alone. The overall success rate (50 % reduction and AHI < 20) was 86.3 %. The mean snore scores (VAS) improved from 8.8 ± 1.2 to 2.0 ± 1.3 (p < 0.001). The mean Epworth score improved from 11.5 ± 2.2 to 2.9 ± 2.1 (p < 0.001). Lowest oxygen saturation also improved in all patients. Subjectively, all the patients felt less tiredness. Pre-operative DISE assessment did not seem to confer any advantage over the patients who had no pre-operative DISE (p = 0.027), and patients who had nose/palate surgery seemed to have better success rates compared to those who only had palate surgery (p = 0.081). This combined technique has been shown to be effective in selected group of OSA patients. Level of evidence IV.
RESUMEN
BACKGROUND: Obstructive sleep apnea (OSA) is a common disorder, and continuous airway positive pressure (CPAP) is considered to be the gold standard of therapy. CPAP however is known to have problems with adherence, with many patients eventually abandoning the device. The purpose of this paper is to assess secular trends in CPAP adherence over the long term to see if there have been meaningful improvements in adherence in light of the multiple interventions proposed to do so. METHODS: A comprehensive systematic literature review was conducted using the Medline-Ovid, Embase, and Pubmed databases, searching for data regarding CPAP adherence over a twenty year timeframe (1994-2015). Data was assessed for quality and then extracted. The main outcome measure was reported CPAP non-adherence. Secondary outcomes included changes in CPAP non-adherence when comparing short versus long-term, and changes in terms of behavioral counseling. RESULTS: Eighty-two papers met study inclusion/exclusion criteria. The overall CPAP non-adherence rate based on a 7-h/night sleep time that was reported in studies conducted over the twenty year time frame was 34.1 %. There was no significant improvement over the time frame. Behavioral intervention improved adherence rates by ~1 h per night on average. CONCLUSIONS: The rate of CPAP adherence remains persistently low over twenty years worth of reported data. No clinically significant improvement in CPAP adherence was seen even in recent years despite efforts toward behavioral intervention and patient coaching. This low rate of adherence is problematic, and calls into question the concept of CPAP as gold-standard of therapy for OSA.

BACKGROUND: Continuous positive airway pressure (CPAP) is typically recommended as first line therapy for obstructive sleep apnea, but the adherence rate of CPAP is problematic. This study's objective was to systematically review the literature relating to CPAP as first line therapy for OSA and compare it to surgical literature on the same topic. METHODS: A systematic review was conducted according to PRISMA guidelines, examining Medline-Ovid, Embase, and Pubmed databases. The primary search objective was to identify all papers reporting the results of (1) randomized clinical trials (RCT) of CPAP for the treatment of adults with OSA; and (2) both randomized and non-randomized clinical trials and case series on the surgical treatment of OSA in adults. A PhD-level biostatistician first screened papers, and then those that met study criteria were retrieved and analyzed using standardized forms for each author. The primary outcomes were adherence rates of CPAP. RESULTS: A total of 82 controlled clinical trials for CPAP and 69 controlled and non-controlled surgery trials were identified for analysis. Variation in CPAP use within reported RCT trials were identified, and the majority of patients in the studies would eventually be considered non-adherent to CPAP. CONCLUSIONS: When considering the numerous patient-related factors that come into play when CPAP is prescribed, the concept of CPAP as gold-standard therapy for OSA should be reconsidered. In many cases surgery can provide a better overall outcome. This study's results suggest that certain patients with OSA may be managed more effectively with surgery than CPAP, without confounding issues of treatment adherence.

OBJECTIVES/HYPOTHESIS: To illustrate the reliability of the Pang-Rotenberg (PR) sign as a prognosticator of snoring surgery. Our hypothesis was that patients who are PR-positive have better snoring reduction scores and outcomes than PR-negative patients after nose and palate surgery. STUDY DESIGN: A multicenter prospective series of 153 patients with snoring. METHODS: All patients graded the snoring intensity on a visual analog scale (VAS). All 137 patients enrolled had both the nose surgery and palate surgery. The control group consisted of 16 patients who underwent nasal surgery alone. RESULTS: There were 122 men and 15 women, the mean age was 44.6 years old, and mean body mass index was 26.1. There were 15 simple snorers and 122 obstructive sleep apnea patients. Patients who were PR-positive showed significantly better postoperative snoring VAS reduction (from 9.04 to 1.02) compared to those patients who were PR-negative (from 8.91 to 3.14) (P < .001). The mean follow-up time was 7.4 months. The control group had poor snoring VAS reduction from 9.21 to 6.72. After adjusting for covariates that influence the snoring VAS change due to surgery, we found that PR-negative patients achieved an average of 5.78 improvement in snoring VAS, whereas PR-positive patients achieved an average of 8.02 improvement in snoring VAS (P < .001). CONCLUSIONS: The PR sign is a reliable prognosticator of snoring reduction, after combined nose and palate surgery, for patients with troublesome snoring.
