Association Between Soft Tissue Measures From Computed Tomography and Upper Airway Collapsibility on Drug-Induced Sleep Endoscopy. Otolaryngol Head Neck Surg 2024; 171:578-587. [PMID: 38613204 DOI: 10.1002/ohn.772] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 02/11/2024] [Accepted: 02/23/2024] [Indexed: 04/14/2024]
Abstract
OBJECTIVE Positive airway pressure (PAP) titration during drug-induced sleep endoscopy (DISE) provides objective measures of upper airway collapsibility. While skeletal measurements relate to collapsibility measures on DISE, the influence of soft tissue dimensions on upper airway collapsibility is not known. We analyzed the relationship of measures of upper airway soft tissue volumes, specifically soft palate, pharyngeal lateral walls, and tongue, with metrics of collapsibility. STUDY DESIGN Cross-sectional analysis from a prospective cohort. SETTING Academic medical center. METHODS Patients seeking PAP alternative therapies for obstructive sleep apnea (OSA) underwent standardized supine computed tomography (CT) acquisition and DISE protocols. The CT analysis primarily focused on soft tissue volumes and, secondarily, on airway and skeletal volumetric measures. DISE with PAP administration (DISE-PAP) enabled the determination of the pressure at which inspiratory airflow first commenced (pharyngeal critical pressure, PcritA) and the pressure at which inspiratory flow limitation was abolished (pharyngeal opening pressure, PhOP). Both unadjusted and adjusted correlation analyses were performed to understand the relationship between upper airway anatomy and either PcritA or PhOP. RESULTS One hundred thirty-nine subjects completed both CT and DISE-PAP. On average, patients were male (70.5%), white (84.2%), middle-aged (56.6 ± 13.5 years), and overweight (29.6 ± 4.7 kg/m2), with moderate-severe apnea-hypopnea index (29.7 ± 21.3 events/h). Adjusted for age, sex, body mass index, and skeletal volumes, soft palate, and lateral pharyngeal wall volumes were not associated with PhOP or PcritA, but a larger tongue was associated with more positive PhOP (⍴ = 0.20, P = .02), and more positive PcritA (⍴ = 0.16, P = .07). Exploratory analyses revealed smaller minimum cross-sectional retropalatal area and intramandibular volume were also associated with increased collapsibility measures. CONCLUSION After controlling for clinical factors and skeletal volume, greater tongue volume was associated with more severe collapsibility during DISE. These results, in concert with previous work, suggest that greater tongue volume in a smaller skeletal dimensions contribute to the severity of airway collapsibility, a key driver of OSA pathogenesis.

Abstract
Pediatric patients with persistent obstructive sleep apnea (OSA) after adenotonsillectomy often have additional sites of upper airway obstruction such as the tongue base or larynx. Sleep endoscopy and cross-sectional, dynamic imaging can be used to direct surgical management of persistent OSA. The tongue base is one of the most common sites of obstruction in children with persistent OSA, especially for patients with Trisomy 21. Lingual tonsillectomy, tongue suspension, and/or posterior midline glossectomy may be used to address lingual tonsil hypertrophy and tongue base obstruction. Epiglottopexy and/or supraglottoplasty may be used to address laryngomalacia and epiglottic prolapse resulting in OSA.

Eur Arch Otorhinolaryngol 2024; 281:1031-1039. [PMID: 37975910 DOI: 10.1007/s00405-023-08333-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Accepted: 11/01/2023] [Indexed: 11/19/2023]
Abstract
PURPOSE To evaluate the percentage of obstructive sleep apnea (OSA) patients with retrolingual obstruction in all moderate-severe OSA patients and the proportions of different causes in all moderate-severe OSA patients with retrolingual obstruction and to discuss the accuracy of the Friedman tongue position (FTP) and retrolingual cross-sectional area (RCSA) in assessing the retrolingual obstruction. METHODS Two hundred and twenty moderate-severe OSA patients were enrolled. After retrolingual obstruction was diagnosed, the percentage of OSA patients with retrolingual obstruction in all moderate-severe OSA patients was calculated. After that, the different causes of retrolingual obstruction were diagnosed based on different diagnostic criteria, and the proportions of different causes in all moderate-severe OSA patients with retrolingual obstruction were calculated. Finally, the correlations between FTP, RCSA, and apnea-hypopnea index after nasopharyngeal tube insertion (NPT-AHI) were analyzed, and the proportions of different causes of retrolingual obstruction based on different FTP and RCSA were observed. RESULTS There were 128 patients with retrolingual obstruction, accounting for 58.2% of all moderate-severe OSA patients. In 128 patients with retrolingual obstruction, the proportions of glossoptosis (48.4%), palatal tonsil hypertrophy (28.1%), and lingual hypertrophy (8.6%) were relatively high. Both FTP and RCSA did not correlate with NPT-AHI. The proportion of lingual hypertrophy increased gradually with the increase of FTP and the proportions of glossoptosis in all FTP classifications were high. The patients with RCSA > 180 mm2 were mainly affected by glossoptosis and palatal tonsil hypertrophy, while patients with RCSA ≤ 180 mm2 were mainly affected by lingual hypertrophy. CONCLUSION The percentage of patients with retrolingual obstruction in all moderate-severe OSA patients is relatively high, mainly glossoptosis, palatal tonsil hypertrophy, and lingual hypertrophy. FTP classification and RCSA can only reflect the retrolingual anatomical stenosis, but cannot fully reflect the retrolingual functional stenosis, especially the presence of glossoptosis.

Otolaryngol Head Neck Surg 2023; 169:412-421. [PMID: 36939430 DOI: 10.1002/ohn.258] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Revised: 12/05/2022] [Accepted: 12/17/2022] [Indexed: 02/10/2023]
Abstract
OBJECTIVE To examine the relationship between craniofacial skeletal anatomy and objective measures of pharyngeal collapse obtained during drug-induced sleep endoscopy. We hypothesized that transverse maxillary deficiency and an increased pharyngeal length will be associated with higher levels of pharyngeal collapsibility. STUDY DESIGN Cross-sectional analysis in a prospective cohort. SETTING University Hospital. METHODS A cross-sectional analysis was conducted in a cohort of consecutive patients from the positive airway pressure (PAP) alternatives clinic who underwent computed tomography (CT) analysis and drug-induced sleep endoscopy for characterization of upper airway collapsibility. PAP titration was used to determine pharyngeal critical pressure (PCRIT ) and pharyngeal opening pressure (PhOP). CT metrics included: Transverse maxillary dimensions (interpremolar and intermolar distances) and pharyngeal length (posterior nasal spine to hyoid distance). RESULTS The cohort (n = 103) of severe obstructive sleep apnea (Apnea and Hipopnea Index 32.1 ± 21.3 events/h) was predominantly male (71.8%), Caucasian (81.6%), middle-aged (54.4 ± 14.3 years), and obese (body mass index [BMI] = 30.0 ± 4.9 kg/m2 ). Reduced transverse maxillary dimensions were associated with higher PCRIT (intermolar distance: β [95% confidence interval, CI] = -.25 [-0.14, -0.36] cmH2 O/mm; p = .03) and PhOP (Interpremolar distance: β = -.25 [-0.14, -0.36] cmH2 O/mm; p = .02). Longer pharyngeal length was also associated with higher PCRIT (β = .11 [0.08, 0.14] cmH2 O/mm, p = .04) and PhOP (β [95% CI] = .06 [0.03, 0.09] cmH2 O/mm, p = .04). These associations persisted after adjustments for sex, age, height, and BMI. CONCLUSION Our results further the concept that skeletal restriction in the transverse dimension and hyoid descent are associated with elevations in pharyngeal collapsibility during sleep, suggesting a role of transverse deficiency in the pathogenesis of airway obstruction.

Abstract
BACKGROUND Evaluation and interpretation of the literature on obstructive sleep apnea (OSA) allows for consolidation and determination of the key factors important for clinical management of the adult OSA patient. Toward this goal, an international collaborative of multidisciplinary experts in sleep apnea evaluation and treatment have produced the International Consensus statement on Obstructive Sleep Apnea (ICS:OSA). METHODS Using previously defined methodology, focal topics in OSA were assigned as literature review (LR), evidence-based review (EBR), or evidence-based review with recommendations (EBR-R) formats. Each topic incorporated the available and relevant evidence which was summarized and graded on study quality. Each topic and section underwent iterative review and the ICS:OSA was created and reviewed by all authors for consensus. RESULTS The ICS:OSA addresses OSA syndrome definitions, pathophysiology, epidemiology, risk factors for disease, screening methods, diagnostic testing types, multiple treatment modalities, and effects of OSA treatment on multiple OSA-associated comorbidities. Specific focus on outcomes with positive airway pressure (PAP) and surgical treatments were evaluated. CONCLUSION This review of the literature consolidates the available knowledge and identifies the limitations of the current evidence on OSA. This effort aims to create a resource for OSA evidence-based practice and identify future research needs. Knowledge gaps and research opportunities include improving the metrics of OSA disease, determining the optimal OSA screening paradigms, developing strategies for PAP adherence and longitudinal care, enhancing selection of PAP alternatives and surgery, understanding health risk outcomes, and translating evidence into individualized approaches to therapy.

Abstract
OBJECTIVE To compare findings of same-day cine magnetic resonance imaging (MRI) and drug-induced sleep endoscopy (DISE) and examine how each technique uniquely contributes to the evaluation of persistent obstructive sleep apnea following adenotonsillectomy. STUDY DESIGN Retrospective cohort study. SETTING Quaternary care center. METHODS Chart review was performed for consecutive patients who underwent same-day cine MRI and DISE between 2015 and 2020. Descriptive statistics are reported, and Cohen kappa coefficients were calculated to evaluate the agreement between cine MRI and DISE for obstruction at the adenoids, lingual tonsils, and tongue base. RESULTS There were 137 patients, the mean age was 10.4 years (95% CI, 3.2-16.7), and 62.8% were male. The most common sites of obstruction on DISE were the tongue base (86.9%), velum (78.7%), epiglottis (74.5%), inferior turbinate (68.6%), and lingual tonsil (61.3%). The most common sites of obstruction on cine MRI were the hypopharynx (56.3%), tongue base (44.8%), lingual tonsil (38.0%), and macroglossia (37.6%). There was moderate agreement for adenoid hypertrophy (κ = 0.53) and poor agreement for lingual tonsil hypertrophy (κ = 0.15) and tongue base obstruction (κ = 0.09). DISE identified more instances of multilevel obstruction when compared with cine MRI (94.9% vs 48.2%). CONCLUSION DISE offered a better examination of nasal and supraglottic obstruction and is sensitive to partial vs complete collapse, while cine MRI offered better soft tissue resolution for lymphoid tissue hypertrophy and provided a global view of primary and secondary airway obstruction. Cine MRI and DISE are complementary modalities in the evaluation of children with persistent obstructive sleep apnea.

Abstract
OBJECTIVES To evaluate the role of clinical scores assessing the risk of disease severity in patients with clinical suspicion of obstructive sleep apnea syndrome (OSA). The hypothesis was tested by applying artificial intelligence (AI) to demonstrate its effectiveness in distinguishing between mild-moderate OSA and severe OSA risk. METHODS A support vector machine model (SVM) was developed from the samples included in the analysis (N = 498), and they were split into 75% for training (N = 373) with the remaining for testing (N = 125). Two diagnostic thresholds were selected for OSA severity: mild to moderate (apnea-hypopnea index (AHI) ≥ 5 events/h and AHI < 30 events/h) and severe (AHI ≥ 30 events/h). The algorithms were trained and tested to predict OSA patient severity. RESULTS The sensitivity and specificity for the SVM model were 0.93 and 0.80 with an accuracy of 0.86; instead, the logistic regression full mode reported a value of 0.74 and 0.63, respectively, with an accuracy of 0.68. After backward stepwise elimination for features selection, the reduced logistic regression model demonstrated a sensitivity and specificity of 0.79 and 0.56, respectively, and an accuracy of 0.67. CONCLUSION Artificial intelligence could be applied to patients with symptoms related to OSA to identify individuals with a severe OSA risk with clinical-based algorithms in the OSA framework.

Abstract
Zusammenfassung
Hintergrund Die Hyperplasie der Zungengrundtonsille ist eine seltene und zugleich auch potenziell gefährliche Veränderung im Bereich der oberen Atemwege. Die Pathogenese der Zungengrundhyperplasie (ZGH) ist immer noch weitgehend unbekannt. Im Rahmen dieser Studie wurde der Zusammenhang zwischen Zustand nach Tonsillektomie und kompensatorischer Zungengrundhyperplasie untersucht.
Material und Methoden In der HNO-Klinik der Medizinischen Hochschule Hannover wurden 300 Patienten konsekutiv untersucht. Im Rahmen der indirekten Laryngoskopie wurden die Zungengrundtonsille, Einsehbarkeit des Larynx sowie seiner Subregionen nach einem Schema beurteilt. Die Daten wurden anschließend in Abhängigkeit vom Status der Gaumentonsillen ausgewertet. Ergänzend wurde der Body-Mass-Index (BMI) ermittelt und mit Ergebnissen der Laryngoskopie verglichen.
Ergebnisse Von den 300 untersuchten Patienten war bei 89 (29,6%) eine Tonsillektomie beidseits durchgeführt worden. In der Gesamtpopulation war eine stark vergrößerte Zungengrundtonsille nur in 14 Fällen (4,6%) nachweisbar. Von diesen 14 wurde bei 4 Patienten in der Vorgeschichte eine Tonsillektomie durchgeführt. Der BMI zeigte bei Patienten mit einer normal großen Zungengrundtonsille einen Wert von 24,4 und bei Patienten mit starker Zungengrundhyperplasie 27,3.
Schlussfolgerungen Die Inzidenz der ZGH fällt nach unseren Ergebnissen mit 4,7 % gering aus. Ein Zusammenhang zwischen einem Zustand nach Tonsillektomie und kompensatorischer Zungengrundhyperplasie konnte nicht nachgewiesen werden. Es zeigte sich jedoch ein statistisch signifikanter Zusammenhang zwischen BMI und ZGH.

[PMID: 36431055 PMCID: PMC9693112 DOI: 10.3390/life12111920] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Revised: 11/15/2022] [Accepted: 11/16/2022] [Indexed: 11/19/2022]
Abstract
This study aimed to evaluate the influence of lingual tonsil (LT) volume measured using a three-dimensional (3D) reconstruction volume rendering program on clinical parameters and polysomnography (PSG) results. A total of 100 patients who underwent PSG, computed tomography (CT), and allergy test from April 2016 to April 2020 were randomly selected. LT volume was measured using an imaging software program that enables 3D reconstruction of CT images. PSG parameters were analyzed by dividing the subjects into two groups according to LT volume (each 50 people). Based on the medial volume of 0.863 cm3, the upper half LT volume group and the lower half LT volume group were analyzed. Clinical factors such as body weight, neck circumference, body mass index (BMI), and age showed no difference between the two groups. Among PSG parameters, supine arousal index and non-rapid eye movement (NREM) arousal index were significantly higher in the upper half LT volume group (p = 0.012, 0.037). However, there was no significant difference in apnea-hypopnea index (AHI) between the upper and lower half LT volume groups (p = 0.749). Arousal snoring index and REM arousal index also showed no difference between the two groups. The prevalence of allergic rhinitis was not different in the two groups. High LT volume is associated with NREM arousal and arousal in the supine position, but it is not related to AHI.

Transoral Tongue Suspension for Obstructive Sleep Apnea-A Preliminary Study. J Clin Med 2022; 11:jcm11174960. [PMID: 36078891 PMCID: PMC9456292 DOI: 10.3390/jcm11174960] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 08/10/2022] [Accepted: 08/20/2022] [Indexed: 11/30/2022] Open
Abstract
Objectives: To evaluate the safety and efficacy of a novel technique for transoral tongue suspension (TOTS) in obstructive sleep apnea (OSA) patients. Material and Methods: The retrospective study enrolled 24 consecutive OSA patients (21 males; average age, 43 years; average apnea−hypopnea index (AHI), 42.2 event/h; average body mass index (BMI), 25.7 kg/m2) with tongue obstruction confirmed by drug-induced sleep endoscopy. All patients received TOTS as the main procedure in conjunction with uvulopalatopharyngoplasty (UPPP). Key procedures of TOTS included a transoral sublabial approach, drilling two holes on the mandible, passing the polypropylene through the hole to the tongue base using a suture passer and returning the polypropylene through loop traction, and tying the polypropylene to the mandible. Lingual tonsil ablation (n = 8) was also implemented in hypertrophic lingual tonsils (grades III and IV). Results: The operation time for TOTS was around 30 min. No wound bleeding or airway compromise occurred throughout the postoperative period. Minor complications were temporary and included swelling of the tongue, numbness of the lower incisor, and sublabial wound dehiscence (n = 2). The quality of life improved significantly in the patients’ subjective daytime sleepiness according to the Epworth Sleepiness Scale (11.4 ± 3.2 vs. 5.7 ± 1.6, p < 0.001). The objective parameters of OSA also improved significantly in the apnea/hypopnea index (42.2 ± 21.8 vs. 19.5 ± 16.2, p < 0.001), minimal oxygen saturation (77.1 ± 12.2 vs. 81.7 ± 8.1, p = 0.026), and snoring index (207 ± 141 vs. 101 ± 91, p = 0.03). Conclusions: The demonstrated TOTS showed its advantage in low morbidity with a scarless exterior and easy performance with free availability in treating adult OSA patients with tongue obstruction. TOTS combined with UPPP significantly improved AHI and daytime sleepiness. TOTS can be implemented with lingual tonsillectomy to achieve both stabilization of the tongue and widening of hypopharyngeal airway.

Abstract
Background: Obstruction of the tongue is commonly seen in patients with obstructive sleep apnea (OSA). This study proposed whole tongue treatment using coblation ablation tongue (CAT) and aimed to explore the potential association between the dimensions of a tongue and the severity of OSA, to inspect volumetric changes of the tongue after CAT, and to search for factors that influence outcome of tongue volume change. Methods: The prospective study enrolled 12 OSA patients (all male, average age: 35 years, average apnea/hypopnea index (AHI): 45.5 event/h, average body mass index (BMI): 27.0 kg/m2). All patients received multi-level sleep surgery including septomeatoplasty, uvulopalatopharyngoplasty, and CAT. The CAT used a coblation wand to perform uniform multiple ablations (15 points, body −6, base −9) on dorsal tongue. Three dimensions of the tongue (length, height, and width) and tongue volume were measured from head and neck computed tomography. The perioperative changes in the tongue dimension/volume and AHI were assessed at baseline and 3 months after surgery. Result: The baseline tongue length and AHI had a significant correlation (r = 0.60, p = 0.02). The multi-level surgery significantly improved AHI (43.8 vs. 23.7, p = 0.008). The CAT significantly decreased tongue volume from 91.3 to 85.6 cm3 (p = 0.02), with an average tongue volume reduction of 5.7 cm3 per person and 0.38 cm3 per ablation. Further outcome analysis showed surgical success was significantly higher in patients with non-hypertrophic lingual tonsils (grade I/II) than in those with hypertrophic lingual tonsils (grade III/IV) (p = 0.02). Conclusion: Length of the tongue is associated with the severity of OSA. The CAT significantly decreased the tongue volume in OSA patients. A volumetric reduction of 0.38 cm3 per ablation could be useful in the optimal reduction of tongue for OSA. The CAT significantly enlarged the retroglossal airway volume, which is related to the non-hypertrophic lingual tonsil.

Multimodal phenotypic labelling using drug-induced sleep endoscopy, awake nasendoscopy and computational fluid dynamics for the prediction of mandibular advancement device treatment outcome: a prospective study. J Sleep Res 2022; 31:e13673. [PMID: 35734809 PMCID: PMC10078177 DOI: 10.1111/jsr.13673] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Revised: 05/11/2022] [Accepted: 05/30/2022] [Indexed: 11/30/2022]
Abstract
Mandibular advancement device (MAD) treatment outcome for obstructive sleep apnea (OSA) is variable and patient dependent. A global, clinically applicable predictive model is lacking. Our aim was to combine characteristics obtained during drug-induced sleep endoscopy (DISE), awake nasendoscopy, and computed tomography scan-based computational fluid dynamic (CFD) measurements in one multifactorial model, to explain MAD treatment outcome. A total of 100 patients with OSA were prospectively recruited and treated with a MAD at fixed 75% protrusion. In all, 72 underwent CFD analysis, DISE, and awake nasendoscopy at baseline in a blinded fashion and completed a 3-month follow-up polysomnography with a MAD. Treatment response was defined as a reduction in the apnea-hypopnea index (AHI) of ≥50% and deterioration as an increase of ≥10% during MAD treatment. To cope with missing data, multiple imputation with predictive mean matching was used. Multivariate logistic regression, adjusting for body mass index and baseline AHI, was used to combine all potential predictor variables. The strongest impact concerning odds ratios (ORs) was present for complete concentric palatal collapse (CCCp) during DISE on deterioration (OR 28.88, 95% confidence interval [CI] 1.18-704.35; p = 0.0391), followed by a C-shape versus an oval shape of the soft palate during wakefulness (OR 8.54, 95% CI 1.09-67.23; p = 0.0416) and tongue base collapse during DISE on response (OR 3.29, 95% CI 1.02-10.64; p = 0.0464). Both logistic regression models exhibited excellent and fair predictive accuracy. Our findings suggest DISE to be the most robust examination associated with MAD treatment outcome, with tongue base collapse as a predictor for successful MAD treatment and CCCp as an adverse DISE phenotype.

Awake endoscopic assessment of the upper airway during tidal breathing: Definition of anatomical features and comparison with drug-induced sleep endoscopy. Clin Otolaryngol 2020; 46:234-242.

Abstract
OBJECTIVES Awake nasopharyngoscopy is routinely performed in the assessment of patients who require treatment for sleep-disordered breathing (SDB). However, the applicability and accuracy of Müller's manoeuvre, the main evaluation method for this purpose, are disputable. The current study aimed to introduce an alternative method for awake nasopharyngoscopy in patients with SDB. DESIGN We defined qualitative anatomical features during tidal breathing at the levels of the soft palate, oropharynx, tongue base, epiglottis and hypopharynx, and compared these awake features to the sites and patterns of collapse as observed during drug-induced sleep endoscopy (DISE). SETTING Tertiary care academic centre. PARTICIPANTS Seventy-three patients diagnosed with SDB. MAIN OUTCOME MEASURES The primary outcome measure was the Kendall's tau correlation coefficient (τ) between observations during awake nasopharyngoscopy and DISE. Kappa-statistics (κ) were calculated to assess the agreement on awake endoscopic features with a second observer. RESULTS In contrast to epiglottis shape, the modified Cormack-Lehane scale was significantly associated with epiglottis collapse during DISE (P < .0001; τ = .45). Other upper airway features that were correlated with DISE collapse were the position of the soft palate (P = .007; τ = .29), crowding of the oropharynx (P = .026; τ = .32) and a posteriorly located tongue base (P = .046; τ = .32). Interobserver agreement of endoscopic features during tidal breathing was moderate (0.60 ≤ κ < 0.80). CONCLUSION The current study introduces a comprehensive and reliable assessment method for awake nasopharyngoscopy based on anatomical features that are compatible with DISE collapse patterns.

Abstract
Introduced in 2010, transoral robotic surgery (TORS) is recognized as an effective treatment of moderate to severe obstructive sleep apnea (OSA) in the setting of lymphoid and muscular tongue base hypertrophy. Upper airway stimulation (UAS) or hypoglossal nerve stimulation has emerged as a promising treatment of patients with moderate to severe OSA who have failed continuous positive airway pressure. UAS has shown favorable success rates and low morbidity compared with traditional soft tissue and skeletal framework surgery. UAS is in its infancy as a surgical procedure and concerns exist regarding narrow candidacy criteria, postimplant device titration, and durability of treatment response.

Abstract
Continuous positive airway pressure (CPAP) is the primary treatment of obstructive sleep apnea/hypopnea syndrome (OSA). Most sleep physicians are in agreement that a certain number of OSA patients cannot or will not use CPAP. Although other conservative therapies such as oral appliance, sleep hygiene and sleep positioning may help some of these patients, there are many who fail all conservative treatments. As experts of upper airway diseases, we often view an airway clearly and help OSA patients understand the importance of assessment and treatment for OSA. Surgery for OSA is not a substitute for CPAP but is an alternative treatment for those who failed conservative therapies and therefore have no other options. Transoral robotic surgery (TORS) is a relatively new technique and a valid option with minor post-operative morbidities for selected OSA patients. In the article, we provide an updated overview of the role and evidence of TORS for the treatment of OSA.

Abstract
Obstruction of the airway is a medical emergency. If it is not treated immediately, rapid and potentially life-threatening hypoxia develops. A 70-year-old woman with a history of hypertension and palatine tonsillectomy presented to our tertiary care hospital with dysphagia, odynophagia, muffled voice, and neck swelling of a one-week duration. She also complained of associated shortness of breath that began two days prior to hospital admittance. Bedside laryngoscopy revealed an enlarged base of the tongue and laryngeal edema, resulting in partial airway obstruction. A CT scan of the soft tissue of the neck revealed that lingual tonsillar hypertrophy (LTH) was the cause of the partial airway obstruction. While being closely monitored, the patient was treated with intravenous corticosteroids and antibiotics. Serial laryngoscopies were performed to track the resolution of the airway obstruction. Her hospital course remained uneventful, and the patient was discharged after four days. Though rare, LTH has a strong propensity to cause airway compromise, and it must be treated at once.

Abstract
BACKGROUND This study evaluates the efficacy of lingual tonsil resection by transoral robotic surgery (TORS) in a large group of patients with recurrent lingual tonsillitis (RLT). METHODS Eighty-four patients with RLT treated with a lingual tonsil surgical resection using TORS were analyzed in terms of their postoperative results, disease recurrence, postoperative dysphagia, and quality of life. RESULTS A reduction of the mean number/year of acute lingual tonsillitis (LT) episodes emerged after surgery (5.17 vs 0.54 events), comparing the mean number of preoperative and postoperative LT episodes, a statistical significance emerged (P = .0001). The postoperative endoscopic evaluation showed 94.1% of patients with absent or poor lymphatic tissue on the tongue base. Evaluation of postoperative dysphagia showed good results with an average score of 85.9 ± 7.5. CONCLUSION This article explains how in patients with chronic LT with medical therapy failure and impaired quality of life, TORS could represent a valid therapeutic option.

Abstract
PURPOSE The objective of this study is to analyse the relationship between the endoscopic signs of laryngo-pharyngeal reflux, the lingual tonsil hypertrophy (LTH) and its inflammation, adopting Narrow Band Imaging (NBI) technology. METHODS We enrolled, as cases, patients with clinical diagnosis of laryngopharyngeal reflux disease (LPRD), a Reflux Symptom Index (RSI) ≥ 13, and a Reflux Finding Score (RFS) ≥ 7. Controls were enrolled among patients who underwent the same transnasal endoscopy, equipped with NBI, with a RSI < 13 and a RFS < 7. Nasopharynx, Lingual Tonsils (LT), Hypopharynx and Larynx were evaluated by two experienced otolaryngologists, who calculated the Reflux Finding Scale (RFS) score and focused their attention on the base of the tongue, observing its surface with NBI technology. RESULTS 82 patients with diagnosis of laryngopharyngeal reflux were enrolled as cases. Mean RFS was 11.7 (SD = 2.9). As controls, we enrolled 80 patients. Mean RFS was 2.7 (SD = 1.63). We found that RFS positivity was associated with a significant increase in LT dimension (2.5 vs 1.1, p < 0.001), with a higher LT crypt inflammation grading (1.8 vs 0.09, p < 0.001) and with a higher Roman Cobblestone pattern grading (1.48 vs 0.11, p < 0.001). A significant correlation between the crypt inflammation and the hyperemia subscore of RFS was present (r = 0.696, p < 0.0001), while it was not possible to find a correlation between crypt inflammation and either diffuse laryngeal edema (r = 0.166, p = 0.135) and posterior commissure hypertrophy (r = 0.089, p = 0.427). CONCLUSIONS NBI allowed us to identify endoscopically the presence of enlarged lingual tonsil, crypt inflammation and superficial mucosal changes, in patients affected by LPRD. LEVEL OF EVIDENCE 2 (prospective, case-control study).

Abstract
Background: Patients with severe obstructive sleep apnea (OSA) require safe and effective surgical treatment. Objectives: To evaluate the effectiveness of combined Z-palatopharyngoplasty (ZPPP) and partial glossectomy via 70-degree endoscopy-assisted coblation (Eco-TBR) on severe OSA. Materials and methods: Twenty-two consecutive patients with severe OSA were enrolled between September 2014 and July 2016. The lingual artery was evaluated by contrasted computed tomography (CT). Drug-induced sleep endoscopy (DISE) was performed to determine the necessity of multilevel surgery. Combined ZPPP and Eco-TBR were performed. Polysomnographic parameters were collected pre-operatively and 6 months post-operatively. Results: No adverse events were observed postoperatively. The short-term ( < 12 months) rate of total surgical effectiveness was 63.6% (14/22), with Friedman classifications as follows: I (1/1), Friedman II (6/10) and Friedman III (7/11). There were no differences between Friedman classification groups. The differences in AHI, apnea index (AI), mean blood oxygen, and percentage of cumulative time with oxygen saturation < 90% (CT 90%) were different compared to preoperative levels. Tonsil size was also significantly larger in the multi-level surgery group (2.14 ± 1.03) compared with the control group (1.13 ± 0.64). Conclusions and significance: Combined ZPPP and Eco-TB is safe and effective, with good surgical effectiveness for the treatment of severe OSA patients.

Abstract
Background Lingual tonsils, part of the Waldeyers’ Ring, are located in base of the tongue. They are commonly observed in childhood, due to increased immunological activity. Several factors such as laryngopharyngeal reflux, younger age, smoking, and obesity are associated with hypertrophy of lingual tonsils (LTH) in adulthood. However, the relation between allergic rhinitis and LTH is not clearly highlightened in the literature so far. Objective To investigate the role of allergic rhinitis in the development of LTH. Methods Adult patients who were diagnosed with allergic rhinitis were included in the study group. The control group consisted of age- and sex-match healthy volunteers. Complete otorhinolaryngology examination including fiberoptic endoscopic evaluation was performed to both groups. Blood samples were obtained for total immunglobulin E levels, and skin prick tests were performed to both groups. Patients with allergy complaints and positive skin prick tests were included in the study group, while healthy volunteers with negative skin prick tests were enrolled in the control group. The grading for LTH was achieved by a physician who was blind to the study. Results The incidence of LTH was significantly higher in the study group when compared to the control group ( P = .001). Similarly, the incidence of grade 3 LTH was significantly higher in the study group compared to the controls ( P = .002). Conclusion According to our results, LTH is more frequently observed in patients with allergic rhinitis. Grade 3 representing larger LTH is more commonly seen in patients with allergic rhinitis.

Abstract
Laryngopharyngeal reflux (LPR) is a clinical entity diagnosed by history laryngoscopic findings that has a variable response to empiric proton-pump inhibitor (PPI) therapy. While the reflux finding score (RFS), an endoscopic scoring scheme, has been advanced as a measure of LPR, it has not been externally validated against symptom severity in practice. Extralaryngeal pharyngeal endoscopic findings may have diagnostic utility but remain underexplored. This study assesses the correlation between extralaryngeal findings and (1) 24-hour oropharyngeal pH & (2) PPI response in patients with suspected LPR. Subjects presented to a tertiary care center with laryngeal symptoms ≥1 month and reflux symptom index (RSI) ≥13. Following baseline questionnaires, laryngoscopy, and a 24-hour oropharyngeal pH probe study, subjects were prescribed 8-12 week omeprazole trials. Baseline endoscopic findings were scored in a blinded fashion using the RFS and extralaryngeal score criteria, summatively the 'ELS.' PPI response was defined as ≥50% improvement in RSI. Thirty-three subjects with flexible endoscopic recordings completed baseline and follow-up questionnaires. The cohort's baseline mean RSI was 23.0 ± 7.2 with a ΔRSI = 9.8 after PPI therapy. The baseline RFS score averaged 5.3 ± 2.7. 45% of our subjects was found to be PPI responsive. The Cohen's kappa for the ELS but not the RFS was significant. There were no significant differences between the RFS (P = 0.10) or ELS (P = 0.07) for PPI responders & nonresponders. Oropharyngeal pH measures did not correlate with the RFS or ELS. In conclusion, endoscopic scores of laryngeal and extralaryngeal findings did not predict PPI response or oropharyngeal acid exposure in suspected LPR.

Abstract
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.

Abstract
OBJECTIVE To conduct a systematic review and meta-analysis to evaluate effects of lingual tonsillectomy with palatal surgery as a combined procedure for the treatment of obstructive sleep apnea (OSA) in adults. SEARCH METHODS Data source: a comprehensive search of MEDLINE, Scopus, Ovid, Web of Science, and the Cochrane Library was performed through November 2017. Manual searches and subject matter expert input were also obtained. This review includes studies assessing efficacy of lingual tonsillectomy with palatal surgery as a combined procedure for the treatment of OSA in adults, who had multilevel obstruction including lingual tonsil hypertrophy, in which apnea/hypopnea index (AHI) or respiratory disturbance index (RDI) were reported. RESULTS A total of four studies (107 patients) met our inclusion criteria. Pooled random effects analysis demonstrated a statistically significant improvement of polysomnographic respiratory events postoperatively, with average AHI reduction of 18.51 events per hour, [95% confidence interval (CI) (- 31.72, - 5.31); P = 0.006] and increase in minimal arterial oxygen saturation of 5.26 [95% CI (0.10, 10.42); P = 0.05]. The result also showed that the procedures significantly improved sleepiness resulting in an average Epworth Sleepiness Scale (ESS) reduction of 5.44 [95% CI (- 8.69, - 2.18); P = 0.001]. CONCLUSION A combination of lingual tonsillectomy with palatal surgery may offer benefits in a selected group of OSA adults, in terms of apnea/hypopnea index, minimal arterial oxygen saturation and Epworth Sleepiness Scale. Data were based on meta-analysis of all case series with 2-6 months' follow-up.

Abstract
Objectives Benign enlargement of the lingual tonsils due to various causes may cause symptoms that warrant treatment. Conventional lingual tonsillectomy remains a challenging procedure, and there is no established standard procedure. We aimed to review the patients receiving different methods of lingual tonsil surgery for various indications at our institute. Methods Retrospective clinical data on all patients with an ablative operation of the tongue base during the 8-year period between 2007 and 2014 at the Helsinki University Hospital, Helsinki, Finland, were reviewed. The larger cohort comprised 35 patients, of whom 26 were men (74%). Ten patients had undergone solely lingual tonsil radio frequency ablation (LTRFA). The minimum follow-up time for all patients was 2 years. Results Of the 10 patients, 5 patients with LTRFA had been operated on because of symptomatic lingual tonsil hypertrophy and 5 because of periodic fever associated with possible lingual tonsil involvement. In 2 of the 5 patients with periodic fever, the fever cycles ended after the operation. Of the 5 patients, 3 patients with symptomatic lingual tonsil hypertrophy have been non-symptomatic after 1 to 3 treatment sessions. The last 2 patients continue to have persistent symptoms. There were no major complications. Conclusions Development of new approaches for the management of various lingual tonsil conditions is warranted. Lingual tonsil volume reduction by LTRFA seems to be a treatment alternative with low morbidity but with limited curative effect only.

Abstract
Objectives To characterize the incidence of lingual tonsil hypertrophy (LTH) in adults with and without obstructive sleep apnea (OSA) and to determine any potential correlation between them. Study Design Retrospective chart review. Setting Single-center database, September 2016 to April 2017. Subject and Methods Lingual tonsil grade (LTG) determined by awake endoscopy was collected as well as other physical examination findings, such as Friedman tongue position, palatine tonsil size, and neck circumference. STOP-BANG scores and polysomnography data were collected to characterize OSA. Incidence of clinically meaningful LTH (defined as LTG 3 and LTG 4) was compared between OSA and non-OSA groups. Results Ninety-three patient charts were studied in total. There was no significant difference between patients with and without OSA in the incidence of clinically meaningful LTH (OSA, 13.5%; non-OSA, 14.6%; P = .872). Patients with and without OSA were compared by grade: LTG 1, 13.5% (OSA) vs 35.6% (non-OSA); LTG 2, 73.1% (OSA) vs 48.8% (non-OSA); LTG 3, 13.5% (OSA) vs 14.6% (non-OSA). There were no significant correlations between OSA status and LTG (ρ = 0.190, P = .069). Conclusion The incidence of LTH is uncommon, even among those with OSA, and does not seem to differ between patients with and without OSA. Neck circumference appears to be a better clinical indicator than lingual tonsil tissue for the likelihood of a patient having OSA.

Abstract
Objectives To analyze correlations between endoscopic lingual tonsil grade (LTG) by the Friedman Lingual Tonsil Hypertrophy grading system and computed tomography (CT) measurements of lingual tonsil thickness (LTT). Study Design Retrospective chart review. Setting Single-center database, September 2016 to April 2017. Subjects and Methods Patients who received CT covering base of tongue and endoscopic LTG were included. LTT was measured on axial and sagittal CT. LTT measurements were compared against endoscopic LTG. One-way analysis of variance with Tukey's post hoc adjustment for multiple comparisons was performed. Results Seventy-five charts were included for a total of 150 LTT measurements. Axial CT measurements of LTG 1 and LTG 2 were each significantly different from LTG 3 ( P < .001 for both), and LTG 1 and LTG 2 also differed significantly ( P = .010). Mean sagittal CT measurements were significantly different between LTG 1 and LTG 3 ( P < .001) and between LTG 2 and LTG 3 ( P = .002) but not between LTG 1 and LTG 2 ( P = .186). Those without lingual tonsil hypertrophy had a mean axial CT thickness of 6.45 ± 1.39 mm and mean sagittal CT thickness of 6.58 ± 1.53 mm, which was significantly different from both the mean axial CT thickness of 8.48 ± 1.52 mm and the mean sagittal CT thickness of 8.07 ± 1.16 mm in the LTG 3 group ( P < .001 for both). Threshold analysis showed a potential cutoff of approximately 7.5 mm on axial and sagittal CT for defining clinically significant lingual tonsil hypertrophy. Conclusion Awake endoscopy grading of lingual tonsil hypertrophy is a subjective measurement that seems to correlate with objective CT measurements. LTT measurements of LTG 1 and LTG 2 on awake endoscopy differed significantly from LTG 3.

Abstract
Background Hypertrophy of the lingual tonsil tissue in the adult patient is thought to contribute to the pathophysiology of obstructive sleep apnea. The underlying etiology of lingual tonsil hypertrophy (LTH) in the adult patient is unclear and likely multifactorial. Previous studies have suggested that the lingual tonsils may undergo compensatory hyperplasia post-tonsillectomy in children, although it is unknown if this occurs or persists into adulthood. The purpose of this study was to determine what factors are associated with LTH in a population of Canadian adults. Methods Adult patients presenting for consultation to an academic Rhinology/General Otolaryngology practice were eligible for enrollment. Demographic data including age, body mass index (BMI), Reflux Symptom Index (RSI), history of allergy, and history of tonsillectomy was collected via questionnaire. Endoscopic photographs of the base of tongue and larynx were captured. These were graded for LTH and Reflux Finding Scale (RFS) by blinded examiners. Statistical analysis was performed by comparing the mean LTH value to the variables of interest using two-tailed T-test. P < .05 was considered significant. Results One hundred two subjects were enrolled. Age ranged from 18 to 78. 28 patients had previous tonsillectomy. This was not associated with a significant increase in lingual tonsil tissue (r = −0.05, p = 0.61). RFS >7 or RSI >13 was considered positive for laryngopharyngeal reflux. There was no difference in LTH based on RSI positivity (p = 0.44). RFS positivity correlated with increased lingual tonsil tissue (p < 0.05). BMI >30 was associated with increased lingual tonsil hypertrophy (p < 0.05). Conclusions An elevated body mass index and positive Reflux Finding Score are associated with lingual tonsil hypertrophy in adults. Reflux symptom index, history of allergy and history of childhood tonsillectomy are not associated with LTH.

Abstract
Lingual tonsil hypertrophy (LTH) is a common finding for children with residual obstructive sleep apnea (OSA) following an adenotonsillectomy. Secondary to the significant morbidity associated with OSA, identification and treatment of residual OSA are paramount. A dedicated LTH grading scale for children does not exist. The current adult LTH scale is impractical for children. Imaging is not routine for children, since it frequently requires sedation. We present a pediatric LTH grading scale with substantial interrater reliability to facilitate standardization of endoscopy findings and promote outcomes-based research for OSA surgery in children.
