Objective:To discuss the application of virtual endoscopy in the diagnosis of adenoid hypertrophy and the morphologic classification of adenoid. Methods:The clinical data of 97 children with adenoid hypertrophy admitted to Department of Otorhinolaryngology Head and Neck Surgery, Shenzhen University General Hospital from July 2022 to December 2022 were collected. The virtual endoscopic reconstruction of the nasopharynx was performed by cone beam computed tomography. The results of virtual endoscopic adenoid size measurement were compared with the results of nasopharyngeal CT median sagittal position and nasopharyngeal endoscopy. Virtual endoscopic classification of adenoid based on the size of the adenoids and their relationship with the torus tubarius. Results:The t-test results of the size of adenoids measured by virtual endoscopy and nasopharyngeal CT were t=1.699 and P=0.093, and the results of intra-group correlation coefficient（ICC） analysis were ICC=0.921 and P<0.01. The proportion of adenoids measured by virtual endoscopy and nasopharyngeal CT was highly consistent. The t-test results of the size of adenoids measured virtual endoscopy and nasopharyngeal endoscopy were t=1.543 and P=0.15, and the results of intra-group correlation coefficient（ICC） analysis were ICC=0.900 and P<0.01. The proportion of adenoids measured by virtual endoscopy and nasopharyngeal endoscopy was highly consistent. Among the 97 children, the morphological classification results of adenoids were 48 cases of overall hypertrophy type, 47 cases of central bulge type, and 2 cases of flat thickening type. Conclusion:The diagnosis of adenoid hypertrophy by virtual endoscopy has high accuracy, which not only avoids the invasive operation of traditional nasopharyngeal endoscopy, but also can observe the adenoid condition and its relationship with the torus tubarius from multiple angles. And, the morphological classification of adenoids using virtual endoscopy has guiding significance for perioperative preparation.

Objective:To investigate the changes of inflammation and immune function in children with chronic tonsillitis after tonsillotomy. Methods:Prospectively collected 60 children with obstructive sleep apnea （OSA） diagnosed as chronic tonsillitis with adenoids and tonsillar hypertrophy from January to June 2021. Two groups were divided, the experimental group （n=30） underwent bilateral partial tonsillectomy + adenoidectomy by hypothermia plasma ablation, and the control group （n=30） underwent adenoidectomy by using the same hypothermia plasma ablation method. The number of tonsillitis attacks before surgery and within one year after surgery was recorded, and the serum immunoglobulin IgM, IgG, IgA, complement C3 and complement C4 levels before operation, one month and three months after operation were measured. Results:The number of tonsillitis attacks in the experimental group and the control group at one year after surgery was lower than that before surgery（P<0.05）; The number of inflammatory attacks in the experimental group was （0.50±0.63） times/year, which was lower than that of （1.33±0.80） times/year in the control group. There was no significant difference in the five immunization results of the two groups at one month and three months after operation compared with before operation, and there was also no significant difference between the experimental and the control groups. Conclusion:Partial tonsillectomy can be applied to children with chronic tonsillitis, which can effectively reduce the number of tonsillitis attacks and has no effect on the immune function of children.

Objective: To assess the incidence of symptomatic torus tubarius hypertrophy (TTH) in recurred OSA in children, and to explore the preliminary experience of partial resection of TTH assisted with radiofrequency ablation. Methods: From January 2004 to February 2020, 4 922 children, who diagnosed as OSA and received adenotonsillectomy at the Department of Otolaryngology, The 4th Medical Center of the PLA General Hospital, were retrospectively reviewed. There were 3 266 males and 1 656 females, the age ranged from 1 to 14 years old(median age of 5.0 years). Twenty-two cases were identified with recurrence of OSA syndrome, and the clinical data, including sex, age of primary operation, age of recurrence and presentation, and opertation methods were analyzed. Follow-up was carried out by outpatient visit or telephone. Graphpad prism 5.0 software was used for statistical analysis. Results: Twenty-two cases were identified as recurred OSA and received revised surgery in 4 922 cases. Among these 22 cases, 11 cases were diagnosed as TTH resulting in an incidence of 2.23‰(11/4 922), 1 case was cicatricial adhesion on tubal torus (0.20‰, 1/4 922), 10 cases were residual adenoid combined with tubal tonsil hypertrophy (2.03‰, 10/4 922). Median age of primary operation was 3.0 years (range:2.4 to 6.0 years) in 11 TTH cases. Recurrent interval varied from 2 months to 5.5 years (2.4±1.9 years) after first operation. Age of revised partial resection of TTH was 7.0±2.7 years (range: 4.0 to 12.0 years). Average time interval between primary operation and revised operation was 3.5±2.1 years (range: 0.5 to 6.0 years). Individualized treatments were carried out based on partial resection of TTH assisted with radiofrequency ablation. All of 11 cases received satisfied therapeutic results without nasopharyngeal stenosis occured. Twenty-two cases were followed up for 1.6 to 13 years (median follow-up time was 6.2 years). Conclusions: TTH contributed to recurred OSA in child. TTH might be misdiagnosed as tubal tonsil hypertrophy. Partial resection of TTH assisted with radiofrequency ablation was a safty and effective treatment.

Objective: To study voice changes in children after adenotonsillectomy or adenoidectomy and the relationship with the vocal tract structure. Methods: Fifty patients were recruited in this study prospectively, aged from 4 to 12 years old with the median age of 6. They were underwent adenotonsillectomy or adenoidectomy in Beijing Tongren Hospital, Capital Medical University from July 2019 to August 2020. In the cases, there are 31 males and 19 females. Thirty-six patients underwent adenotonsillectomy and 14 patients underwent adenoidectomy alone. Twenty-two children (13 males, 9 females) with Ⅰ degree of bilateral tonsils without adenoid hypertrophy and no snoring were selected as normal controls. Adenoid and tonsil sizes were evaluated. Subjective changes of voice were recorded after surgery. Moreover, voice data including fundamental frequency(F0), jitter, shimmer, noise to harmonic ratio(NHR), maximum phonation time(MPT), formant frequencies(F1-F5) and bandwidths(B1-B5) of vowel/a/and/i/were analyzed before, 3 days and 1 month after surgery respectively.SPSS 23.0 was used for statistical analysis. Results: Thirty-six patients(72.0%,36/50) complained of postoperative voice changes. The incidence was inversely correlated with age. In children aged 4-6, 7-9, and 10-12, the incidence was 83.3%(25/30), 63.6%(7/11) and 44.4%(4/9) respectively. Voice changes appeared more common in children underwent adenotonsillectomy(77.8%,28/36) than in those underwent adenoidectomy alone(57.1%,8/14), but there was no statistical difference. After operation, for vowel/a/, MPT(Z=2.18,P=0.041) and F2(t=2.13,P=0.040) increased, B2(Z=2.04,P=0.041) and B4(Z=2.00,P=0.046) decreased. For vowel/i/, F2(t=2.035,P=0.050) and F4(t=4.44,P=0.0001) increased, B2(Z=2.36,P=0.019) decreased. Other acoustic parameters were not significantly different from those before surgery. The F2(r=-0.392, P =0.032) of vowel/a/and F2(r=-0.279, P=0.048) and F4 (r=-0.401, P =0.028) of vowel/i/after adenotonsillectomy were significantly higher than those of adenoidectomy alone. Half of patients with postopertive voice changes can recover spontaneously 1 month after surgery. Conclusions: Voice changes in children underwent adenotonsillectomy or adenoidectomy might be related to their changes in formants and bandwidths. The effect of adenotonsillectomy on voice was more significant compared with that of adenoidectomy alone. The acoustic parameters did not change significantly after surgery except MPT.

BACKGROUND AND OBJECTIVES: Partial intracapsular tonsillectomy and adenoidectomy (PITA) has become a well-recognized technique for tonsillectomy in children. Several studies have reported that PITA shows better postoperative morbidity compared to the conventional technique. However, there is still concern about the regrowth of remnant tonsil tissues. The authors evaluated the postoperative results of PITA, combined extracapsular and intracapsular tonsillectomy, and conventional tonsillectomy. SUBJECTS AND METHOD: The authors studied 97 children (male: 62, female: 35) aged 2 to 13 years old, who underwent tonsillectomy and adenoidectomy (PITA, combined extracapsular and intracapsular tonsillectomy, and conventional tonsillectomy). The degree of adenotonsillar hypertrophy, apnea-hypopnea index and lowest oxygen saturation was confirmed for all subjects. Operation time, quality of life, scale for postoperative pain, frequency of postoperative bleeding, and recurrence with tonsillar regrowth were compared after surgery performed by different surgical procedures. RESULTS: Regardless of the surgical technique, all the cases presented significant improvement in the quality of life before and after surgery. On the day of surgery and four days after surgery, PITA showed superior results in terms of postoperative pain level compared to the conventional technique. There were no statistically significant results with respect to the operation time and postoperative bleeding. Six months after the surgery, the recurrence of sleep apnea due to the regrowth of remaining tonsil was not obvious. CONCLUSION: Tonsillectomy technique preserving tonsillar capsule may show better results on early postoperative pain. It can be a good alternative to the conventional technique in surgical treatment for pediatric obstructive sleep apnea in terms of early postoperative pain control.

OBJECTIVES: Although adenotonsillar hypertrophy is the main cause of sleep-disordered breathing in children, surrounding anatomic factors, such as the width of the nasopharynx, can affect upper airway patency. However, there have been no reports of the association of nasopharyngeal width with sleep-disordered breathing in children. This study was undertaken to measure nasopharyngeal width in children undergoing adenotonsillectomy for sleep-disordered breathing and to investigate the clinical implications of this factor. METHODS: This was a retrospective study with a follow-up period of 1 year, performed at a tertiary referral center. We reviewed the operative records of children who underwent adenotonsillectomy at our center for symptoms of sleep-disordered breathing, such as snoring, apnea, and mouth breathing. The nasopharyngeal width was measured immediately before adenotonsillectomy, which was performed under general anesthesia with a microscopy-assisted mirror view. Adenotonsillar hypertrophy was graded on a four-point scale, and symptoms of sleep-disordered breathing were evaluated by using the Korean version of the Obstructive Sleep Apnea-18 questionnaire before and after surgery. The relationships between the average nasopharyngeal width and patient age and sex, adenotonsillar hypertrophy, and the Korean version of the Obstructive Sleep Apnea-18 score were analyzed. RESULTS: The study included 549 children (343 boys) with a mean age of 6.0 years (range, 2 to 11 years). The average nasopharyngeal width was 11.9 mm (range, 7.0 to 18.0 mm) and increased with age (range, 11.2 to 13.3; β=0.264; P<0.001). At 1 year after surgery, children with a greater nasopharyngeal width at the time of surgery exhibited additional improvements in symptoms of obstruction relative to those at 1 month after surgery. CONCLUSION: The average nasopharyngeal width in children is approximately 11.9 mm and exhibits a slight increase with age. The width of the nasopharynx may be a factor associated with the degree of improvement in symptoms of sleep-disordered breathing after adenotonsillectomy.

Upper airway myofunctional exercise is a training technique for patients with obstructive sleep apnea involving isotonic and isometric exercises of the upper airway muscles involved in obstructive sleep apnea designed to strengthen upper airway myofunction and improve patients' symptoms. The objective of this review was to evaluate the safety and effectiveness of upper airway myofunctional exercise. A literature search was conducted using 8 Korean databases, Medline, Embase, and the Cochrane Library. Of the 197 articles that were initially identified, 8 studies were included in this review. The results show that upper airway myofunctional exercise improved the apnea-hypopnea index in adult patients, and that it led to improvements in symptoms and upper airway myofunction when administered alone or after adenoidectomy in pediatric patients. On the basis of the current data, upper airway myofunctional exercise can be considered a safe and effective technique for patients with obstructive sleep apnea.

PURPOSE: Periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome is a leading cause of periodic fever in children. This study describes the clinical characteristics of PFAPA syndrome in patients from a single center.METHODS: Thirteen children diagnosed with PFAPA syndrome at Seoul National University Children's Hospital were included in this study. Retrospective medical chart reviews were performed.RESULTS: Among the 13 patients, 8 (61.5%) were male. The median follow-up duration was 3.3 years (range, 10 months–8.3 years). The median age of periodic fever onset was 3 years (range, 1–6 years). All patients had at least 5 episodes of periodic fever and pharyngitis, managed with oral antibiotics, before diagnosis. The median occurrence of fever was every 3.9 weeks and lasted for 4.2 days. All patients had pharyngitis and 12 (92.3%) had cervical lymphadenitis. Blood tests were performed for 12 patients, and no patients had neutropenia. Both the C-reactive protein and erythrocyte sedimentation rate were elevated at medians of 4.5 mg/dL (range, 0.4–13.2 mg/dL) and 29 mm/hr (range, 16–49 mm/hr), respectively. Throat swab cultures and rapid streptococcal antigen tests were negative. Nine (69.2%) patients received oral prednisolone at a median dose of 0.8 mg/kg, and in 6 (66.7%) patients, fever resolved within a few hours. Three (23.1%) patients received tonsillectomy and adenoidectomy.CONCLUSIONS: PFAPA syndrome should be considered when a child presents with periodic fever along with aphthous stomatitis, pharyngitis, or cervical lymphadenitis. Glucocorticoid administration is effective for fever resolution and can reduce unnecessary use of antibiotics.
