RESUMO
Introduction Obstructive sleep apnea (OSA) is a severe form of sleep-disordered breathing (SDB) that is strongly correlated with comorbidities, in which epiglottic collapse (EC) and other contributing factors are involved. Objectives To evaluate the occurrence of EC in OSA patients through drug-induced sleep endoscopy (DISE) and to determine the factors contributing to EC. Methods A retrospective study of 37 adult patients using medical history. Patients were assessed for laryngopharyngeal reflux (LPR) and lingual tonsil hypertrophy (LTH) using reflux symptom index and reflux finding score (RFS); for OSA using polysomnography, and for airway collapse through DISE. An independent t -test was performed to evaluate risk factors, including the involvement of three other airway structures. Results Most EC patients exhibited trap door epiglottic collapse (TDEC) (56.8%) or pushed epiglottic collapse (PEC) (29.7%). Lingual tonsil hypertrophy, RFS, and respiratory effort-related arousal (RERA) were associated with epiglottic subtypes. Laryngopharyngeal reflux patients confirmed by RFS (t(25) = -1.32, p = 0.197) tended to suffer PEC; LTH was significantly associated (X2(1) = 2.5, p = 0.012) with PEC (odds ratio [OR] value = 44) in grades II and III LTH patients; 11 of 16 TDEC patients had grade I LTH. Pushed epiglottic collapse was more prevalent among multilevel airway obstruction patients. A single additional collapse site was found only in TDEC patients. Conclusion Laryngopharyngeal reflux causes repetitive acid stress toward lingual tonsils causing LTH, resulting in PEC with grade II or III LTH. Trap door epiglottic collapse requires one additional structural collapse, while at least two additional collapse sites were necessary to develop PEC. Respiratory effort-related arousal values may indicate EC.

RESUMO
OBJECT: Recurrent tonsillitis and tonsillar hypertrophy are two common diseases in children for which tonsillectomy is the definitive solution. The underlying causes of both diseases are not fully known. The aim of this study was to identify the predominant innate lymphoid cells in both diseases of the palatine tonsils, which are known to play an important role in the immune system. METHODS: Children who underwent tonsillectomy were divided into two groups as recurrent tonsillitis and tonsillar hypertrophy according to the indication for surgery. The proportions of innate lymphoid cell (ILC) groups and IFN-gamma, IL-10 and IL-17 secreting T lymphocyte cells were determined in tonsil and blood samples obtained during surgery. Local and peripheral immune responses were evaluated. Innate immune responses and acquired immune responses were compared. RESULTS: The results of our study showed that the proportions of the innate lymphoid cell 1 group (ILC1) were similar in tonsil tissue in patients with recurrent tonsillitis and tonsil hypertrophy, with no statistically significant difference. It was observed that the innate lymphoid cell 2 group (ILC2) was the predominant group in tonsil hypertrophy, the innate lymphoid cell 3 group (ILC3) was the predominant innate lymphoid cell group in recurrent tonsillitis, and the proportion of IL-17 secreting T lymphocytes in blood and tonsillar mononuclear cells was higher in recurrent tonsillitis patients than in tonsil hypertrophy patients. CONCLUSION: With the results obtained, the predominant innate lymphoid cells in the pathogenesis of both diseases were identified and local and peripheral responses were compared. These findings may be a guide for possible medical treatments for both diseases in the future.

Otitis media with effusion (OME) affects approximately 80% of children due to the middle ear being flooded with fluids, though with no microbial infection manifestations. Multiple issues can drive recurring pediatric OME, such as environment-based issues, previous medical issues, inherited vulnerability from family, contact time at childcare institutes, passive smoking, and more than three siblings together with atopy or allergic rhinitis. If OME is not promptly addressed, this could eventually result in hearing impairment or loss, with consequent negative repercussions on the child's communicative and behavioral patterns. OME diagnosis within the clinic is possible, with hearing capacity being assessed pre- and post-therapy. Adenoid hypertrophy (AH) represents a typical causative factor for middle-ear conditions, stemming from mechanical or anatomical issues. Consequently, adenoid size is paramount when determining tympanometry types and ear fluids. This systematic review investigated PubMed, Medline, Cochrane Library, and Science Direct databases in order to retrieve knowledge related to this issue, adopting inclusion and exclusion criteria and maintaining review quality through the employment of the Assessment of Multiple Systematic Reviews (AMSTAR), the Newcastle-Ottawa tool, and the Axis scale. This systematic review analyzed a previous review article, six observation-based investigations, and three cross-sectional investigations. Previous randomized controlled trials (RCTs) were not found within previous literature, suggesting such scarcity in this research niche and thus warranting future RCT investigations based on this compelling research niche.
RESUMO
Objective: The present study was developed to explore risk factors related to the incidence and severity of obstructive sleep apnea syndrome (OSAS) in children. Methods: The present study enrolled pediatric patients who admitted to our department for snoring and/or open-mouth breathing. All children completed a questionnaire and underwent physical examination and polysomnography (PSG). The cases were separated into OSAS and primary snoring (PS) groups. Factors associated with these two groups were analyzed, with risk factors significantly associated with OSAS then being identified through logistic regression analyses. OSAS was further subdivided into mild, moderate, and severe subgroups, with correlations between risk factors and OSAS severity then being analyzed. Results: In total, 1,550 children were included in the present study, of which 852 and 698 were enrolled in the OSAS and PS groups. In univariate analyses, obesity, family passive smoking, a family history of snoring, allergic rhinitis, asthma, adenoid hypertrophy, and tonsil hypertrophy were all related to pediatric OSAS (P < 0.05). In a multivariate logistic regression analysis, adenoid hypertrophy (OR:1.835, 95% CI: 1.482-2.271) and tonsil hypertrophy (OR:1.283, 95% CI:1.014-1.622) were independently associated with the risk of pediatric OSAS (P < 0.05). Stratification analyses revealed that OSAS incidence increased in a stepwise manner with increases in adenoid and tonsil grading (P < 0.01). Correlation analyses revealed that adenoid hypertrophy and tonsilar hypertrophy were not significantly associated with OSAS severity (r = 0.253, 0.069, respectively, P < 0.05), and tonsil and adenoid size were no correlation with obstructive apnea-hypopnea index (OAHI) (r = 0.237,0.193, respectively, P < 0.001). Conclusion: Obesity, family passive smoking, a family history of snoring, allergic rhinitis, asthma, tonsil hypertrophy, and adenoid hypertrophy may be potential risk factors for pediatric OSAS. Adenoid hypertrophy and tonsil hypertrophy were independently related to the risk of pediatric OSAS, with OSAS incidence increasing with the size of the adenoid and tonsil, while the severity of OSAS is not parallel related to the adenoid or tonsil size.
RESUMO
Background and Objectives: Obstructive sleep apnea (OSA) is a sleep-related respiratory disorder that affects between 5% and 20% of the population. In obstructive sleep apnea, lingual tonsillar hypertrophy (LTH) has been suggested as a contributing factor to airway blockage. Objectives: The aim of this work is to demonstrate the polysomnographic indices and their values in OSA patients with LTH before and after the surgical intervention. Materials and Methods: The study was conducted on eighteen patients endoscopically diagnosed as having LTH, with the main complaints being snoring, sleep apnea, and/or sleep disturbance. Clinical examination, grading of LTH, body mass index (BMI), endoscopic assessment using Muller's maneuver, and sleep endoscopy were recorded for all patients. The Epworth Sleepiness Scale (ESS) and overnight sleep polysomnography (PSG) were conducted before and after the surgical removal of LTH. All data were submitted for statistical analysis. Results: The mean ± SD of the AHI decreased from 33.89 ± 26.8 to 20.9 ± 19.14 postoperatively, and this decrease was of insignificant statistical value. The average SpO2 (%) mean ± SD was 91.14 ± 5.96, while the mean ± SD of the desaturation index was 34.64 ± 34.2. Following surgery, these indices changed to 96.5 ± 1.47 and 9.36 ± 7.58, respectively. The mean ± SD of the ESS was changed after the surgery, from 17.27 ± 6.48 to 7.16 ± 3.56. The mean ± SD of sleep efficacy was 71.2 ± 16.8 and the snoring index mean ± SD was 277.6 ± 192.37, and both improved postoperatively, to become 88.17 ± 9.1 and 62.167 ± 40.01, respectively. Conclusions: The AHI after lingual tonsillectomy showed no statistically significant change. The changes in the average SpO2 (%), desaturation index, sleep efficiency, snoring index, and Epworth Sleepiness Scale following the surgery were statistically significant.

OBJECTIVE: To summarize the results of a study of the clinical and polygrapic features of sleep in children with pathologic conditions of the tonsillar ring and obstructive sleep apnea. Tonsillar hypertrophy is the most common cause of obstructive sleep apnea in children. Using the data of overnight polysomnographic study and/or nocturnal pulse oximetry, groups of patients were distinguished depending on the presence and severity of their sleep breathing disorders. The effectiveness of adenotomy, adenotonsillotomy and/or adenotonsillectomy in children is demonstrated, depending on the severity of obstructive sleep apnea syndrome. Evaluation of breathing in sleeping children by polygraphic methods is necessary for early detection of obstructive sleep apnea syndrome and monitoring the effectiveness of surgical treatment.

Abstract: Eleven years old children, proposed for resection of pylocitic astrocytoma of cerebellum, presented with lingual tonsil hypertrophy causing a unpredictable difficult airway approach. The presence of a lingual tonsil hypertrophied isn't diagnosed most of the times, with their occurrence being associated with previous tonsillectomy in more than half of the cases. Its occurrence, and non-identification, can originate scenarios of difficult airway approach, with a higher morbility association.
Resumen: Niño con 11 años, propuesto para exéresis de recidiva de astrocitoma pilocítico del cerebelo con hipertrofia de las amígdalas linguales a condicionar vía aérea difícil no previsible. La hipertrofia de las amígdalas linguales es subdiagnosticada y se suele asociar a amigdalectomía previa en más de la mitad de los casos. Su ocurrencia y no reconocimiento, puede originar situaciones de vía aérea difícil, con alta morbilidad asociada.
RESUMO
BACKGROUND: Orthopedic surgery for cervical torticollis poses potential threat to airway management both in tracheal intubation and extubation. Klippel-Feil syndrome (KFS) is a complex syndrome of osseous and visceral anomalies. The anatomical characteristics of KFS might have significant implications for airway management. CASE PRESENTATION: This is a rare case of an 8-year-old boy presenting with osseous torticollis, congenital occipito-atlantal deformity, congenital basilar invagination and KFS undergone elective torticollis correction surgery. Though with difficulty, tracheal intubation was successfully performed. Extubation failed twice on postoperative day 2 and 10, and required tracheostomy. Based on radiological findings, we speculated that prolonged airway edema accounted for the main reason of the failed extubation, the hypertrophic tonsil and occipito-cervical fusion resulted in reduced oropharyngeal space and limited cervical range of motion. Moreover, the Chiari malformation and KFS complicated the airway condition and lead to prolonged airway obstruction. The tracheostomy casing was removed 1 month later. CONCLUSIONS: Cautions should be taken in extubation of pediatric patients undergone major osseous torticollis surgery. Reintubation should be prepared in case of failed extubation. Severe post-operative airway edema, complicated with hypertrophic tonsil, the structural abnormalities in the oropharyngeal cavity, and occipito-cervical deformities constituted the decreased oropharyngeal space and resulted in failed extubation. For severe airway compromise and prolonged intubation, tracheostomy should be considered.

OBJECTIVE: The aim: Grounding on the electronic microscopy of PT make conclusions about the tonsil activity in adults depending on the accompanied pathology of nose and PS. PATIENTS AND METHODS: Materials and methods: Ultramicroscopic examination of 111 patients with PT hypertrophy aged 18-55 was done. Depending on the nose and PS pathology (inflammatory, non-inflammatory) patients' PS biopsic materials were distributed into 2 groups: 58 cases on inflammatory and 53 on non-inflammatory background. The control group consisted of 24 patients aged 18 without nose and PS pathology. The images of ultrathin PT sections were received with the help of transmission electronic microscope PEM - 125 with digital camera (SELMI, Sumy). RESULTS: Results: Great variations in PT cell condition, depending on the pathology were distinguished. Features of the adenoiditis in inflammatory and non-inflammatory diseases of nose and PS were proved. CONCLUSION: Conclusions: 1. PT ultra-microscopy in control group shows great activity of lymphocytes and high energy exchange of cells, with prevailing B-lymphocyte population. 2. The complex of PT ultra structural changes while nose and PS inflammatory diseases shows the activation of immune reaction in competent cells with T-lymphocyte increase in patients older than 25, which witnesses chronic inflammation. 3. In group with nose and PT non-inflammatory diseases, activity of PT B-lymphocytes is unchanged accompanied by the T-lymphocytes growth, which is also characteristic for chronic inflammation.

AIM: To evaluate the feasibility of a two-stage screening strategy for otitis media with effusion (OME) in pre-school and school children. The risk factors of OME were also studied. METHODS: One hundred and eighty-nine children aged 4-8 years were recruited. The two-stage screening consisted of an on-site screening with a portable otoscopy along with a questionnaire to both diagnose children with OME and identify children at risk, and a standard screening performed at a regional hospital for final diagnosis. The prevalence detected from the two-stage screening approach was compared to the actual prevalence. RESULTS: The detection rate of OME through the two-stage screening approach was not significantly different from the actual prevalence rate (12.7% vs. 13.4%, P = 0.847). Children from the urban area had a lower risk for OME than that from the rural area (P = 0.007, odds ratio (OR) = 0.28, 95% confidence interval (CI): 0.11-0.74). Compared to childcare dining, family dining helped to reduce the chance of OME (P < 0.001, OR = 0.15, 95% CI: 0.06-0.38). CONCLUSIONS: The two-stage screening strategy was effective for screening for OME among pre-school and school children. It can be used in rural areas that have a high prevalence of OME and limited medical resources.

Objective: To study the relationship between adenoid hypertrophy, tonsillar hypertrophy and overweight or even obesity in children. Methods: A total of 799 children aged 2 to 12 years with tonsillar and adenoid hypertrophy from January 2015 to December 2019 in the Department of Otolaryngology Head Neck Surgery, the Sixth Medical Center of Chinese PLA General Hospital were selected. The body mass index (BMI) was calculated according to the height and weight measured routinely at the time of admission. The difference of BMI between children and normal children of the same age, and the correlation between adenoid, tonsil hypertrophy and obesity were compared. Chi-square test was used to compare the surgical children's BMI of different genders with normal children of the same age, and Spearman rank correlation was used to analyze the correlation between BMI and adenoid and tonsil hypertrophy. Results: The Spearman correlation coefficient between tonsil hypertrophy and BMI was 0.078, P=0.077, the Spearman correlation coefficient between adenoid hypertrophy and BMI was -0.058(P=0.100). χ(2) test showed that the proportion of overweight and obesity in school-age children (7~12 years old) was significantly higher than that in preschool children (2~6 years old), and the difference was statistically significant (χ(2)(male)=22.386, P(male)<0.001, χ(2)(female)=4.478, P(female)<0.001). Conclusion: There is no obvious correlation between adenoid hypertrophy, tonsil hypertrophy and overweight or obesity in children, but the probability of children overweight or obesity increases with age, and the proportion of obesity in children aged 7-12 years is higher.

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).

The authors studied the reporting documentation of otorhinolaryngological hospitals of the city of Moscow on the surgical treatment of pharyngeal pathology in adults from 2002 to 2017. It was found that for 16 years surgical treatment of 290 362 patients with ENT-diseases was performed: 181.206 (62.4%) patients with diseases of the nose and paranasal sinuses, 24.981 (8.6%) patients with ear pathology, 60.346 (20.8%) patients with diseases of the pharynx and 23.829 (8.2%) - with diseases of the larynx. The assessment of the overall dynamics of the studied indicators was carried out on the 'trend lines'. For the considered period, the number of patients with surgical pathology of the pharynx increased by 33.2%. The proportion of tonsillectomies increased by 1.85 times to 56.5%, drainage of peritonsillar abscesses and abscesses-tonsillectomies decreased by 19%, uvulopalatoplastic increased 4.1 times, removal of neoplasms of the pharynx increased 2.2 times, adenotomies decreased by 2.4 times. Analysis of the data allowed to establish that, against the background of an ever-increasing number of surgical interventions for diseases of the pharynx in adults, a descending trend was noted only in the treatment of complicated forms of chronic tonsillitis and hypertrophy of the pharyngeal tonsil.

Lingual tonsils are normal components of the oropharynx localized at the base of the tongue, which sometimes can become enlarged by inflammation. This may be a cause of unexpected difficult airway, considering most patients are asymptomatic and this supraglottic mass is not usually detected during a routine preoperative airway assessment. Commonly described in adults, there are limited reports in pediatric patients. We describe a case of a 12 years old boy diagnosed with a cerebellar brain tumor that was scheduled for a resection. The first surgery was postponed because of respiratory complications as a result of unexpected difficult airway due to lingual tonsil hypertrophy. His surgery was rescheduled and a plan for airway management was laid out: fibroscopic intubation with spontaneous ventilation. Considering this is a problem that cannot be identified by regular airway examination, we should be aware of the most effective ways to manage the situation as it arises.

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.

CONCLUSIONS: Patients with body mass index (BMI) < 25 kg/m2 and obstructive sleep apnea syndrome (OSAS) are highly suspicious for position-dependent OSAS. Diagnosis of position-dependent/position-independent OSAS can be difficult in patients satisfying both 'BMI >25 kg/m2' and 'any of tongue enlargement (TE), palatine tonsil hypertrophy (PTH) and obstruction by Muller's maneuver (OMM)'. Polysomnography is warranted in such patients. OBJECTIVES: The objective was to retrospectively elucidate criteria for differentiating position-dependent OSAS on the basis of patient information and physical examinations of the upper airway obtainable in clinics. METHODS: The 643 patients were categorized as positional patients (PPs) or non-positional patients (NPPs). The patient background factors examined were sex, age, BMI, and hypertension. TE, PTH, pharyngeal tonsil hypertrophy, and OMM were evaluated. Cross-validation was performed using even-numbered registrations as the training set group (Group A) and odd-numbered registrations as the test case group (Group B). RESULTS: In Group A, patients with BMI <25 kg/m2 were clearly more frequent among PP than among NPP. In Group A with BMI ≥25 kg/m2, significant differences were found for TE, PTH and OMM. Significant differences were found between 0 and 1/2/3 for number of factors. Results generated from Group A were validated in Group B.

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.
