Abstract
PURPOSE Snoring and obstructive sleep apnoea (OSA) exhibit multifactorial aetiologies; mouth breathing increases airway obstruction and upper respiratory tract resistance. Of the many published studies, few have evaluated sleeping subjects. We explored how mouth breathing affected the upper respiratory tract anatomy and OSA during sleep. METHODS Eighteen patients with OSA, confirmed via full-night polysomnography, were enrolled in this study. We performed drug-induced sleep endoscopy (DISE) and defined obstruction sites before and after mouth closure using commercial mouth strips. We evaluated obstruction sites in two ways, i.e. by grading obstructions using our DISE grading system and measuring the affected areas. Patients who improved by at least one DISE grade were defined as responders. Areas were measured based on DISE videos analysed using ImageJ software. The apnoea-hypopnoea index (AHI) and body mass index (BMI) were recorded. RESULTS Based on the DISE grade, 40% (7/18) of patients showed obstruction site improvement. When assessed areally, the mean number of pixels improved significantly at both the retropalatal (p = 0.045) and retrolingual (p = 0.019) levels. However, DISE non-responders exhibited no areal improvements. Responders and non-responders did not differ significantly in terms of AHI or BMI (both p < 0.05). CONCLUSIONS Mouth closure improves or at least does not lead to further deterioration of the upper airway. Improvements were evident at the retropalatal and especially retrolingual levels. Neither the BMI nor the AHI differed between the two groups. However, responders tended to have a higher AHI than non-responders (39.4 vs. 32.8 events/h).

Abstract
Background: Continuous mouth breathing results not only morphological deformations but also poor learning outcomes. However, there were few studies that observed correlations between mouth breathing and cognition. This study aimed at investigating the changes in brain activity during mouth breathing while the participant simultaneously performed a cognitive task using electroencephalography (EEG).Methods: Twenty subjects participated in this study, and EEG electrodes (32 channels, 250-Hz sampling rate) were placed on their scalp. Brain waves during a resting state and n-back tasks (0-back and 2-back) and physiological parameters such as SpO2, ETCO2, and the airway respiratory rate were measured. The pre-processed EEG signals were analyzed based on their frequencies as delta waves (0.5 ∼ 4 Hz), theta waves (4 ∼ 8 Hz), alpha waves (8 ∼ 13 Hz), beta waves (13 ∼ 30 Hz) and gamma waves (30 ∼ 50 Hz) using fast Fourier transform (FFT).Results: When compared with nose breathing, theta and alpha powers were lower during mouth breathing at rest and alpha wave presented low power at 0-back and 2-back tasks. Furthermore, beta and gamma waves exhibited low powers at 2-back task. However, the behavioral results (accuracy and response time) have no significant difference between two breathing methods (mouth and nose). Mouth breathing showed different brain activity patterns, compared to nose breathing, and these changes are related to cognitive regions.Conclusion: The reason for this change seems to relate to the decreased oxygen saturation during mouth breathing, suggesting that when cognitive abilities are required, mouth breathing can act as one of the variables that cause different outcomes in brain activities.

Impact of adenotonsilectomy on nasal airflow and pulmonary blood pressure in mouth breathing children. Int J Pediatr Otorhinolaryngol 2019; 125:82-86. [PMID: 31271972 DOI: 10.1016/j.ijporl.2019.06.025] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2019] [Revised: 06/24/2019] [Accepted: 06/24/2019] [Indexed: 11/27/2022]
Abstract
INTRODUCTION Adenotonsillar hyperplasia (ATH) causing upper airway obstruction (UAO) may increase pulmonary artery systolic pressure (PASP). Early diagnosis and mouth breathing (MB) management may help in cases of high PASP. Total inspiratory nasal airflow (TINAF) obtained by active anterior rhinomanometry (AARM) is a means to quantify nasal patency. This study aimed to correlate TINAF with high PASP. METHODS This is a prospective study involving 30 children between two and twelve years of age, with indication for adenotonsillectomy due to ATH, evaluated before and six months after surgery; and 29 nasal breathing (NB) children in the same age group. We obtained the PASP, calculated for tricuspid regurgitation, by means of a transthoracic echocardiography. We assessed nasal patency using the AARM to estimate the TINAF. RESULTS The mean PASP among mouth breathing children was 25.99 mmHg, with a Standard Deviation of (±) 3.27, p = 0.01 in the preoperative period; and 21.79 mmHg (±2.48; p = 0.01) in the postoperative period. Among nasal breathers, this mean value was 21.64 mmHg (±3.87, p = 0.01). The mean pre-operative TINAF was 266.76 cm3/s (±112.21, p = 0.01); and 498.93 cm3/s (±137.80, p = 0.01) after surgery. Among nasal breathers it was 609.37 cm3/s (±109.16; p = 0.01). The mean nasal patency in the preoperative period was 42.85% (±17.83; p = 0.01); and 79.33% (±21.35; p = 0.01) in the post-op. Among nasal breathers it was 112.94% (±15.88, p = 0.01). There was a significant Spearman correlation value between TINAF and PASP (r = -0.459; p = 0.01) when we analyzed all the groups. CONCLUSION PASP and TINAF values improved postoperatively and had an inverse correlation. This study suggests that by improving TINAF there was a decrease in PASP.

Abstract
BACKGROUND The prevalence of vertical facial growth is very high in the developed world. Most authors agree that mouth breathing is its main cause. Even though care is mainly conducted by odontologists, the professionals who first see these patients are pediatricians and otolaryngologists. The objective of this study is to analyze the ability of pediatricians and otolaryngologists to identify early signs of vertical facial growth among children. METHODS 60 participant aged 4.1-13.7 years were analyzed subjectively by 9 otolaryngologists, 9 pediatricians and two specialists in dentofacial orthopedics. They were also assessed objectively with cephalometric analysis. RESULTS Otolaryngologists showed 34.78% sensitivity, 92.86% specificity and 48.33% efficiency. Pediatricians showed 13.04% sensitivity, 100% specificity and 33.33% efficiency. Using a linear regression model compared against the objective measurements we found a weak positive correlation both for otolaryngologists and pediatricians. CONCLUSION The sensitivity was very low for both groups. We believe it is of paramount importance to increase the awareness and the ability of otolaryngologists and pediatricians to recognize signs of disrupt facial growth.

Abstract
Nasal obstruction causes mouth breathing, and affects the growth and development of craniofacial structures, muscle function in the stomatognathic system, and the taste perceptive system. However, the detailed mechanism underlying the effects of nasal obstruction on taste perception has not been fully elucidated. In this study, we investigated this mechanism using the two-bottle taste preference test, immunohistological analysis, and quantification of the mRNA expression of taste-related molecules in the circumvallate papillae. Neonatal male Wistar rats were divided randomly into control and experimental groups. Rats in the experimental group underwent unilateral nasal obstruction by cauterization of the external nostril at the age of 8 days. Arterial oxygen saturation (SpO2) was recorded in awake rats using collar clip sensors. Taste preference for five basic taste solutions was evaluated. Immunohistochemical analysis and quantitative real-time polymerase chain reaction (RT-PCR) were conducted to evaluate the expressions of taste-related molecules in the taste cells of the circumvallate papillae. Body weights were similar between the two groups throughout the experimental period. The SpO2 in the 7- to 12-week-old rats in the experimental group was significantly lower than that in the age-matched rats in the control group. In the two-bottle taste preference test, the sensitivities to sweet taste decreased in the experimental group. The mRNA expression of T1R2, T1R3, α-gustducin, and PLCβ2 was significantly lower in the experimental group than in the control group as determined by quantitative RT-PCR, and the immunohistochemical staining for α-gustducin and PLCβ2 was less prominent. These findings suggest that nasal obstruction may affect sweet taste perception via the reduced expression of taste-related molecules in the taste cells in rat circumvallate papillae.

Abstract
Background When mouth breathing becomes habitual, it can cause sleep disorders and abnormal maxillofacial growth, thus early detection of habitual mouth breathing is important. We created a questionnaire for early detection of habitual mouth breathing using a score based on a spectrum of factors found to be characteristic of mouth breathers. Methods First, a draft 50-question questionnaire was given to 101 random dental clinic patients, classified by dental professionals into habitual mouth breathers (n = 28) and nose breathers (n = 73). The 10 questions that significantly differentiated mouth and nose breathers (p < 0.05) were identified from this questionnaire. These questions, regarding nasal obstruction, open mouth at rest, awareness of mouth breathing, gum swelling and dental staining of the front teeth, bad breath, maxillary protrusion, nasal obstruction in childhood, bottle-feeding, and history of asthma, formed the basis for a second questionnaire. This second survey was completed by another 242 participants, separately classified into mouth breathing (n = 26), suspected mouth breathing (n = 40), and nose breathing groups (n = 176). Results Receiver operating characteristic curve analysis of the resulting mouth breathing habit scores, representing the responses to the 10-question survey, showed moderate checklist diagnosability. Sensitivity of cut-off values was 61.5% (specificity 92.0%) for the mouth-breathing group, and 77.5% (specificity 56.3%) for the suspected mouth-breathing group. Information was also obtained from visual assessment of maxillofacial characteristics. We found that the mouth-breathing and suspected mouth-breathing groups showed significantly high odds ratios for 7 items: discomfort while breathing and increased chin muscle tonus with lip closure, maxillary protrusion, tongue thrust, open mouth at rest, open bite, and childhood asthma. For 94.6% of the nose breathing group, ≥1 of these items applied. Conclusions These findings were then used together to create a sample screening form. We believe that screening of this kind can facilitate more accurate diagnosis of habitual mouth breathing and contribute to its early detection.

Abstract
OBJECTIVES The aim of the study was to investigate the prevalence of upper respiratory tract infections (URI) - as indicated by rhinosinusitis (RS), ear infections (EI), and antibiotic consumption - in a general pediatric population and evaluate the relationship between these conditions and habitual snoring and mouth breathing during sleep. METHODS A population-based cross-sectional study was performed in three medium-sized Polish cities from 2011 to 2015. RESULTS 4837/6963 questionnaires (69.5%) were completed, returned and analyzed. Mean age of studied group was 7.07 ± 0.72 and 7.14 ± 0.73 in girls and boys, respectively. Habitual mouth breathing during sleep (MB) was reported in 907 (18.7%) children and habitual snoring (HS) in 290 (6.0%). 230/290 (79.3%) of children with HS were also MB. Both HS and MB were more prevalent in boys than in girls (p = 0.027 and p < 0.0001, respectively) and neither was associated with BMI (p = 0.11 and p = 0.07, respectively). Habitual snoring and habitual mouth breathing were highly associated with more frequent bouts of rhinosinusitis, ear infections, and antibiotic use (p < 0.0001 for each parameter). CONCLUSIONS Higher rates of rhinosinusitis, ear infections, and antibiotic consumption were similarly associated with HS and MB. MB is over three times more prevalent in the pediatric population relative to HS, therefore it might be considered as a risk factor for URI and may be included in history of URI.

Abstract
Introduction Imaging studies have hystorically been used to support the clinical otorhinolaryngological evaluation of the upper respiratory tract for the diagnosis of obstructive causes of oral breathing. Objective The objective of this study was to compare 3D volumetric measurements of nasal cavity, nasopharynx and oropharynx of obstructed mouth-breathing children with measurements of non-obstructed mouth-breathing children. Methods This retrospective study included 25 mouth-breathing children aged 5–9 years evaluated by otorhinolaryngological clinical examination, flexible nasoendoscopy and full-head multi-slice computed tomography. Tomographic volumetric measurements and dichotomic otorhinolaryngological diagnosis (obstructed vs. non-obstructed) in three anatomical regions (the nasal cavity, nasopharynx and oropharynx) were compared and correlated. An independent sample t-test was used to assess the association between the 3D measurements of the upper airways and the otorhinolaryngological diagnosis of obstruction in the three anatomical regions. Inter- and intra-observer intraclass correlation coefficients were used to evaluate the reliability of the 3D measurements. Results The intra-class correlation coefficients ranged from 0.97 to 0.99. An association was found between turbinate hypertrophy and nasal cavity volume reduction (p < 0.05) and between adenoid hyperplasia and nasopharynx volume reduction (p < 0.001). No association was found between palatine tonsil hyperplasia and oropharynx volume reduction. Conclusions (1) The nasal cavity volume was reduced when hypertrophic turbinates were diagnosed; (2) the nasopharynx was reduced when adenoid hyperplasia was diagnosed; and (3) the oropharynx volume of mouth-breathing children with tonsil hyperplasia was similar to that of non-obstructed mouth-breathing children. The adoption of the actual anatomy of the various compartments of the upper airway is an improvement to the evaluation method.

Abstract
INTRODUCTION Nasal obstruction is a common symptom in childhood, related to rhinitis and pharyngeal tonsil hypertrophy. In the presence of nasal obstruction, nasal patency may be reduced, and nasal breathing is replaced by mouth breathing. Orofacial and otorhinolaryngologic changes are related to this breathing mode. Objective evaluation of upper airways may be obtained through nasal patency measurement. OBJECTIVE To compare nasal patency and otorhinolaryngologic-orofacial features in children. METHODS One hundred and twenty three children, 6-12 year-old, and of both sexes underwent speech therapy evaluation, according to Orofacial Myofunctional Evaluation protocol, clinical and endoscopic otorhinolaryngologic examination and nasal patency measurement, using the absolute and predicted (%) peak nasal inspiratory flow values. RESULTS Lower values of absolute and estimated peak nasal inspiratory flow values were found in children with restless sleep (p=0.006 and p=0.002), nasal obstruction report (p=0.027 and p=0.023), runny nose (p=0.004 and p=0.012), unsystematic lip closure during mastication (p=0.040 and p=0.026), masticatory speed reduced (p=0.006 and p=0.008) and altered solid food swallowing (p=0.006 and p=0.001). Absolute peak nasal inspiratory flow was lower in children with pale inferior turbinate (p=0.040), reduced hard palate width (p=0.037) and altered speech (p=0.004). Higher absolute values were found in children with increased tongue width (p=0.027) and, higher absolute and predicted (%) in children with mild everted lip (p=0.008 and p=0.000). CONCLUSIONS Nasal patency was lower in children with restless sleep, rhinitis signs and symptoms, hard palate width reduced and with changes in mastication, deglutition and speech functions. It is also emphasized that most of the children presented signs and symptom of allergic rhinitis.

Abstract
The aim of our study was to assess long-term results of radiofrequency volumetric tissue reduction of inferior turbinates (RVTR). We performed a prospective long-term longitudinal evaluation of 305 patients affected by rhinitis (114 allergic and 191 non-allergic) who were unresponsive to medical treatment and underwent RVTR (January 2004 - December 2010). Subjects were followed for a mean period of 39.70 ± 19.41 months (range 24-60). Patients completed the NOSE-scale questionnaire pre- and post-operatively after 1 month and yearly for 5-years. Recurrence was assumed if the post-operative total NOSE score increased by at least 75% during follow-up and the patient restarted medical treatments. Estimation of relapse over time was performed by Kaplan-Meyer analyses. We documented overall good satisfaction of patients regarding the procedure, with a good rate of pain control and a low rate of complications. Post-operatively there was a significant improvement in nasal stuffiness, nasal obstruction and mouth breathing (p < 0.05). We observed a worsening trend for symptoms after 36 months with progressive increasing rate of recurrences that were significantly higher in allergic than non-allergic patients (p < 0.05). We also observed a slight worsening trend of global satisfaction of patients. Our study confirms the minor discomfort and low risk of side effects of RVTR. Our data showed good efficacy of the procedure in the majority of patients for at least 36 months after surgery, and in fact in this time period the cumulative probability to remain relapse-free was up to 0.8. In the following 2 years, we observed a worse temporal trend in term of recurrence rate, and in particular in allergic patients with a significant difference vs non-allergic individuals (p < 0.05).

Abstract
The ratio of bad habits, mouth breathing and malocclusion is an important issue in view of prevention and early treatment of disorders of the craniofacial growth. While bad habits can interfere with the position of the teeth and normal pattern of skeletal growth, on the other hand obstruction of the upper airway, resulting in mouth breathing, changes the pattern of craniofacial growth causing malocclusion. Our crosssectional study, carried out on 3017 children using the ROMA index, was developed to verify if there was a significant correlation between bad habits/mouth breathing and malocclusion. The results showed that an increase in the degree of the index increases the prevalence of bad habits and mouth breathing, meaning that these factors are associated with more severe malocclusions. Moreover, we found a significant association of bad habits with increased overjet and openbite, while no association was found with crossbite. Additionally, we found that mouth breathing is closely related to increased overjet, reduced overjet, anterior or posterior crossbite, openbite and displacement of contact points. Therefore, it is necessary to intervene early on these aetiological factors of malocclusion to prevent its development or worsening and, if already developed, correct it by early orthodontic treatment to promote eugnatic skeletal growth.

Abstract
Background Deformity in the dental arc and facial skeleton by adenoid hypertrophy due to chronic mouth breathing is a well-known process. Most of the related studies have been based on cephalometric analyses. The aim of this study is to detect the presence of skeletal deformities on the soft tissue by analyzing distances and angles on photographs. Methods Ninety-seven children having between 25 and 100 % of adenoids, ages 4–12 years (48 boys, 49 girls), and 90 cases having 0–25 % adenoid tissue, ages 4–12 years (54 boys, 36 girls), were studied by clinical history, physical examination (including endoscopy), and standardized clinical photographs. The children and parents were asked if any of the following were present in the children: snoring, sleep apnea, daytime sleepiness, poor school performance, mouth breathing during sleep, smoking parents, and restlessness during sleep. Results The assessment of linear and angular measurements on the clinical photographs showed, in the group having thicker adenoids compared with controls, a statistically significant increase in the distance between nasion and tip and nasion and subnasale and in the angle between Frankfort horizontal plane-gnathion-angulus mandible; there was also a statistically significant decrease in the distance between endocanthion and exocanthion and the angles between tragion-angulus mandible and gnathion and between nasion-angulus mandible and gnathion. Conclusions The analyses showed a significant increase in the anterior face height and increase in the angle between Frankfort horizontal plane-gnathion-angulus mandible and a retropositioned and posterior-rotated mandible due to thicker adenoids.

Abstract
OBJECTIVES Exercise induced bronchospasm (EIB) represents a common feature of childhood asthma which is most commonly revealed during free running. On the other hand aerobic exercise shows significant beneficial effects in asthmatics especially on the reduction of the level of systemic inflammation and is recommended as part of its treatment. The aim of this study was to test how mandatory mouth breathing influences the exercise induced level of decrease in lung function according to the level of severity of allergic rhinitis (AR). METHODS Free 6-minute running test preceded and followed by spirometry done with and without a nose clip a day apart was conducted in 55 children with moderate persistent asthma and AR. Children were divided into two groups according to the severity of nasal symptoms. RESULTS There was a greater fall in forced expiratory volume in one second after exercise with a nose clip in children with less nasal symptoms than in children with more nasal symptoms (mean ± SD; -5.28 (7.91) vs. -0.08 (4.58), p = 0.0228) compared to testing without the nose clip (mean ± SD; LNS, -1.31 ± 3.89%, p = 0.2408; MNS, -1.47 ± 3.68%, p = 0.2883). CONCLUSION Our results show that regular mouth breathing due to nasal congestion may lessen the degree of EIB in patients with persistent AR and allergic asthma.

Abstract
OBJECTIVE To measure the maxillary dentoskeletal and soft tissue changes of severely obstructed mouth breathing (MB) young children who had their mode of breathing normalized after adenotonsillectomy (T&A), in comparison with a matched group of severely obstructed untreated MB children (CG). METHODS Seventy patients who had an Ear, Nose, and Throat examination (ENT), including flexible nasal endoscopy, to confirm the severe obstruction of the upper airways and the indication of T&A composed the sample. Cephalograms and dental casts were available from the patient's orthodontic records. Treatment group (TG) and CG included 35 children each. Groups were matched by gender (24 males and 11 females in each group), age (TG, 6.7 ± 1.8 years; CG, 6.9 ± 2.3 years), tooth development (TG, 13 primary dentition, 22 mixed dentition; CG, 14 primary dentition, 21 mixed dentition), and skeletal maturation status. Records were taken at baseline (T0) and 1-year after T&A (T1) for TG; while CG records were taken with a 1-year interval. Dentoskeletal measurements were performed in the lateral cephalograms, and dental casts were used to assess the palatal volume and occlusal changes. RESULTS TG showed a significant increase (503.3 mm(3), P < 0.001) in the palatal volume (10% of change), while CG palatal volume was stable. No dimensional occlusal changes were detected between T0 and T1 in both groups. Significant downward (point A, 2.1 mm; ANS, 2.1 mm) and forward displacements (point A, 0.7 mm; ANS, 1 mm) of the anterior region of the maxilla were observed in the TG, but CG presented only significant downward displacement (point A, 1.8 mm; ANS, 1.4 mm). The maxillary posterior region (PNS, PTM, and Molar) displaced downward in both groups (P < 0.05), however no sagittal change was found. The palatal plane inclination was stable in both groups. CONCLUSIONS TG presented significant increase in the palatal volume and in the forward displacement of the maxilla. No other significant maxillary dentoskeletal changes were found.

Abstract
AIM Mouth breathing is a functional disorder that affects craniofacial and dento-alveolar growth and also upper airway (UA) anatomy. This is apparent mainly in dimensional abnormalities of the UA caused by hypertrophy of Waldeyer's ring and excessive vertical development of the lower part, giving rise to labial incompetence that perpetuates the functional disorder. The main aim of this study was to evaluate the development of the oropharyngeal structures in young hyperdivergent patients who had undergone functional genioplasty in the context of orthodontic treatment. METHODS This is a comparative retrospective study performed on 47 adolescents who were hyperdivergent, non-obese and exclusive or diurnal mouth breathers, treated at the Centre de soins, d'enseignement et de recherche dentaires (CSERD) in Montpellier, France. All were candidates for early genioplasty for vertical reduction, and were undergoing or at the end of treatment: 23 had been treated surgically (functional genioplasty), and 24 controls had received orthodontic treatment alone. Inter-group comparison of the changes in cephalometric measurements of the oro- and nasopharyngeal zones and maxillomandibular measurements was performed using covariance analysis (ANCOVA) to adjust for confounding factors. RESULTS Concerning the skeletal structures: in the sagittal dimension, genioplasty led to significantly greater projection of the symphysis in the surgical group than in the control group (P<0.001). However, the sagittal position of the hyoid bone was unchanged. Similarly, in the vertical dimension, the reduction in divergence of the bony base was significantly greater in the surgical group (P<0.001), but with no change in the vertical position of the hyoid bone. Concerning the upper airways: at the level of the nasopharynx, there was a significantly greater increase in the velopharyngeal space in the surgical group (P<0.033). The same observation can be made on the level of the oropharynx, where there was a significant increase in the linguopharyngeal space in the surgical group (P<0.05), which was not the case in the control group. The change in the depth of the pharynx did not differ significantly between the two groups. CONCLUSION Early genioplasty performed on adolescents during the growth phase helps to recalibrate the UA by encouraging spontaneous lip closure.

Abstract
INTRODUCTION Adenotonsillar hypertrophy (AH) is considered the most common cause of upper respiratory tract obstruction among children. It results in a spectrum of symptoms from mouth breathing, nasal obstruction, hyponasal speech, snoring, and obstructive sleep apnea (OSA) to growth failure and cardiovascular morbidity. Adenotonsillectomy is a typical strategy for patients with AH, but may lead to serious complications such as bleeding (4-5%) and postoperative respiratory compromise (27%), especially among young children, as well as recurrence of adenoid tissue (10-20%). Thus, non-surgical therapies have attracted considerable attention as an alternative strategy. The inflammatory mechanism proposed for AH has lead to the use of anti-inflammatory drugs to manage this condition. The present study aimed to evaluate the effect of chewable tablets of montelukast, a cysteinyl- leukotriene receptor antagonist, in children with AH. MATERIALS AND METHODS Sixty children between the ages of 4-12 years with >75% choanal obstruction on primary nasal endoscopy were recruited in this randomized, placebo-controlled trial and randomly divided into two groups. The study group was treated with montelukast 5 mg daily for 12 weeks while the control group received matching placebo for the same period of time. A questionnaire was completed by each child's parent/guardian to assess the severity of sleep discomfort, snoring, and mouth breathing before and after the intervention. RESULTS Adenoid size decreased in 76% of the study group compared with 3% of the placebo group after 12 weeks. A statically significant improvement was observed in the study group compared with the placebo group in terms of sleep discomfort, snoring, and mouth breathing. The symptoms average total score dropped from 7.7 to 3.3 in the study group, while in the placebo group the total score changed from 7.4 to 6.7. CONCLUSION Montelukast chewable tablets achieved a significant reduction in adenoid size and improved the related clinical symptoms of AH and can therefore be considered an effective alternative to surgical treatment in children with adenoid hypertrophy.

Abstract
OBJECTIVE To examine the effect of mouth breathing on chewing efficiency by evaluating masticatory variables. MATERIALS AND METHODS Ten adult nasal breathers with normal occlusion and no temporomandibular dysfunction were selected. Subjects were instructed to bite the chewing gum on the habitual side. While breathing through the mouth and nose, the glucide elution from the chewing gum, number of chewing strokes, duration of chewing, and electromyography (EMG) activity of the masseter muscle were evaluated as variables of masticatory efficiency. RESULTS The durations required for the chewing of 30, 60, 90, 120, 180, and 250 strokes were significantly (P < .05) longer while breathing through the mouth. There was no significant difference in the glucide elution rate (%) for each chewing stroke between nose and mouth breathings. The glucide elution rates for 1- and 3-minute chewing were significantly (P < .05) lower while breathing through the mouth. However, there was no significant difference in the glucide elution rate for 5-minute chewing between nose and mouth breathings. While chewing for 1, 3, and 5 minutes, the chewing stroke and EMG activity of the masseter muscle were significantly (P < .05) lower during mouth breathing. CONCLUSIONS It takes a longer amount of time to complete chewing to obtain higher masticatory efficiency when breathing through the mouth. Therefore, mouth breathing will decrease the masticatory efficiency if the duration of chewing is restricted in everyday life.

Abstract
BACKGROUND Adenotonsillectomy (T&A) may not completely eliminate sleep-disordered breathing (SDB), and residual SDB can result in progressive worsening of abnormal breathing during sleep. Persistence of mouth breathing post-T&As plays a role in progressive worsening through an increase of upper airway resistance during sleep with secondary impact on orofacial growth. METHODS Retrospective study on non-overweight and non-syndromic prepubertal children with SDB treated by T&A with pre- and post-surgery clinical and polysomnographic (PSG) evaluations including systematic monitoring of mouth breathing (initial cohort). All children with mouth breathing were then referred for myofunctional treatment (MFT), with clinical follow-up 6 months later and PSG 1 year post-surgery. Only a limited subgroup followed the recommendations to undergo MFT with subsequent PSG (follow-up subgroup). RESULTS Sixty-four prepubertal children meeting inclusion criteria for the initial cohort were investigated. There was significant symptomatic improvement in all children post-T&A, but 26 children had residual SDB with an AHI > 1.5 events/hour and 35 children (including the previous 26) had evidence of "mouth breathing" during sleep as defined [minimum of 44 % and a maximum of 100 % of total sleep time, mean 69 ± 11 % "mouth breather" subgroup and mean 4 ± 3.9 %, range 0 and 10.3 % "non-mouth breathers"]. Eighteen children (follow-up cohort), all in the "mouth breathing" group, were investigated at 1 year follow-up with only nine having undergone 6 months of MFT. The non- MFT subjects were significantly worse than the MFT-treated cohort. MFT led to normalization of clinical and PSG findings. CONCLUSION Assessment of mouth breathing during sleep should be systematically performed post-T&A and the persistence of mouth breathing should be treated with MFT.

Abstract
BACKGROUND It is recognized that adenotonsillar hypertrophy leads to muscular and functional changes in face, and that adenotonsillectomy is associated to improvement in this condition. However, the ideal interval one should wait until this spontaneous recovery is not well defined, neither if this recovery is expected to be complete or partial. OBJECTIVE To compare the muscular and functional changes in face of children prior and after adenotonsillectomy in a monthly evaluation. METHODS 8 children aged from 4 to 6 years were prospectively studied. All patients underwent adenotonsillectomy, and were assessed before and monthly-after surgery up to 6 months, through the Protocol of Orofacial Myofunctional Evaluation with Scores (OMES). RESULTS There was a progressive improvement in OMES score in all measured parameters, including the "mobility" and "posture" sub-tests; this improvement was significant at the first month after surgery. The sub-test "function" was not affected by surgery. Improvement continued from the first to the sixth month after surgery, although it was not significant between these two periods. Additionally, all parameters remained altered after the final evaluation at six months. There was a significant correlation between the improvement in "mobility" sub-test and in total score of OMES. CONCLUSION We observed a partial recovery in facial muscular and functional changes following adenotonsillectomy, particularly during the first month after surgery. This improvement was especially observed in the "mobility" and "posture" sub-tests. We conclude that waiting for a spontaneous muscular and functional facial recovery during the first month post-operatively seems reasonable. Nevertheless, after this period, if the patient fails to achieve recovery, it may be advised that this child should undergo myofunctional therapy.

Abstract
Objective The objective of the present study was to evaluate current radiographic parameters
designed to investigate adenoid hypertrophy and nasopharyngeal obstruction, and to
present an alternative radiographic assessment method. Materials and Methods In order to do so, children (4 to14 years old) who presented with nasal
obstruction or oral breathing complaints were submitted to cavum radiographic
examination. One hundred and twenty records were evaluated according to
quantitative radiographic parameters, and data were correlated with a
gold-standard videonasopharyngoscopic study, in relation to the percentage of
choanal obstruction. Subsequently, a regression analysis was performed in order to
create an original model so the percentage of the choanal obstruction could be
predicted. Results The quantitative parameters demonstrated moderate, if not weak correlation with
the real percentage of choanal obstruction. The regression model (110.119*A/N)
demonstrated a satisfactory ability to "predict" the actual percentage of choanal
obstruction. Conclusion Since current adenoid quantitative radiographic parameters present limitations,
the model presented by the present study might be considered as an alternative
assessment method in cases where videonasopharyngoscopic evaluation is
unavailable.

Abstract
BACKGROUND Nasorespiratory function and its relation to craniofacial growth are of great interest because of the basic biological relationship between form and function, and the accumulating findings of the relationship between mode of breathing, craniofacial growth and orthodontic treatment. OBJECTIVES The aim of this study was to evaluate the effect of adenoid hypertrophy and sociodemographic variables on the occlusion of children. METHODOLOGY A total of 180 subjects aged 3-12 years were selected at the Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria. Ninety subjects had hypertrophied adenoids while 90 normal children served as the control group. Orthodontic examinations were carried out and impressions for study models taken. Occlusion was assessed in the anterior-posterior, transverse and vertical planes. RESULTS Class I relationship was the most prevalent occlusion in both adenoid and control subjects (55.6% and 72.2%, respectively). The occurrence of class II division 1 was significantly higher among adenoid than control subjects (P=0.003). Posterior crossbites occurred significantly more in adenoid subjects in the 9-12 years category. In the vertical plane, the occurrence of deep bite was significantly greater in male than female adenoid subjects. Age had a statistically significant but weak correlation with anterior open bite (r=0.37). Age and BMI also had significant though weak correlations with posterior crossbite in female adenoid subjects (r=0.39 and r=0.36, respectively). Regression analysis also showed that age had a significant effect on the occurrence of anterior open bite, while BMI had a significant effect on the occurrence of class II occlusion in adenoid subjects (P<0.05). CONCLUSION The presence of hypertrophied adenoids affects the occlusion in the three planes. Age and BMI have significant effects on the occurrence of anterior open bite and class II division 1 malocclusion respectively in adenoid subjects.

Abstract
OBJECTIVE To test the null hypothesis that mouth-breathing (MB) children by distinct obstructive tissues present a similar cephalometric pattern. METHODS The sample included 226 prepubescent children (113 MB and 113 nasal breathing (NB) controls). An ENT clinical examination, including flexible nasal endoscopy, orthodontic clinical and cephalometric examinations, was performed on the MB population. MB children were grouped into three categories, according to the obstructive tissues: 1) adenoid group (AG), 2) tonsillar group (TG), and 3) adenotonsillar group (ATG). The NB controls were matched by gender, age, sagittal dental relationship and skeletal maturation status. Lateral cephalometric radiography provided the cephalometric pattern comparisons between the MB and NB groups. RESULTS MB cephalometric measurements were significantly different from those of NB children, exception in the SNB° (P=0.056). All comparisons between the three groups of MB children with the NB children showed a significant difference. Finally, even among the three groups of MB children, a significant difference was observed in the measurements of the SNB° (P<0.036), NSGn° (P<0.028) and PFH/TAFH ratio (posterior facial height/total anterior facial height) (P<0.012). CONCLUSIONS The cephalometric pattern of MB and NB children was not similar. Cephalometric measurements of the MB group differed according to the etiology of upper airway obstruction. Children with isolated hypertrophy of the palatine tonsils presented with a mandible that was positioned more forward and upward compared to children obstructed only by the enlarged adenoid.

Abstract
INTRODUCTION When there is a change in the physiological pattern of nasal breathing, mouth breathing may already be present. The diagnosis of mouth breathing is related to nasal patency. One way to access nasal patency is by acoustic rhinometry. OBJECTIVE To systematically review the effectiveness of acoustic rhinometry for the diagnosis of patients with mouth breathing. METHODS Electronic databases LILACS, MEDLINE via PubMed and Bireme, SciELO, Web of Science, Scopus, PsycInfo, CINAHL, and Science Direct, from August to December 2013, were consulted. 11,439 articles were found: 30 from LILACS, 54 from MEDLINE via Bireme, 5558 from MEDLINE via PubMed, 11 from SciELO, 2056 from Web of Science, 1734 from Scopus, 13 from PsycInfo, 1108 from CINAHL, and 875 from Science Direct. Of these, two articles were selected. RESULTS The heterogeneity in the use of equipment and materials for the assessment of respiratory mode in these studies reveals that there is not yet consensus in the assessment and diagnosis of patients with mouth breathing. CONCLUSION According to the articles, acoustic rhinometry has been used for almost twenty years, but controlled studies attesting to the efficacy of measuring the geometry of nasal cavities for complementary diagnosis of respiratory mode are warranted.

Abstract
Rapid maxillary expansion (RME) is a widely used practice in orthodontics. Scientific evidence shows that RME can be helpful in modifying the breathing pattern in mouth-breathing patients. In order to promote the restoration of physiological breathing we have developed a rehabilitation program associated with RME in children. The aim of the study was a literature review and a model of orofacial rehabilitation in children with obstructive sleep apnea undergoing treatment with rapid maxillary expansion. Muscular training (local exercises and general ones) is the key factor of the program. It also includes hygienic and behavior instructions as well as other therapeutic procedures such as rhinosinusal washes, a postural re-education (Alexander technique) and, if necessary, a pharmacological treatment aimed to improve nasal obstruction. The program should be customized for each patient. If RME is supported by an adequate functional rehabilitation, the possibility to change the breathing pattern is considerably amplified. Awareness, motivation and collaboration of the child and their parents, as well as the cooperation among specialists, such as orthodontist, speech therapist, pediatrician and otolaryngologist, are necessary conditions to achieve the goal.

Abstract
PURPOSE Adenoid hypertrophy is a physical alteration that may affect speech, and a speech disorder can have other negative effects on a child's life. Airway obstruction leads to constricted oral breathing and causes postural alterations of several oro-facial structures, including the mouth, tongue, and hyoid bone. The postural modifications may affect several aspects of speech production. METHODS In this study, we compared articulation errors in 19 children with adenoid hypertrophy (subject group) to those of 33 children with functional articulation disorders independent of anatomical problems (control group). RESULTS The mean age of the subject group was significantly higher (P=0.016). Substitution was more frequent in the subject group (P=0.003; odds ratio [OR], 1.80; 95% confidence interval [CI], 1.23-2.62), while omission was less frequent (P<0.001; OR, 0.43; 95% CI, 0.27-0.67). Articulation errors were significantly less frequent in the palatal affricative in the subject group (P=0.047; OR, 0.25; 95% CI, 0.07-0.92). The number of articulation errors in other consonants was not different between the two groups. Nasalization and aspiration were significantly more frequent in the subject group (P=0.007 and 0.014; OR, 14.77 and 0.014; 95% CI, [1.62-135.04] and NA, respectively). Otherwise, there were no differences between the two groups. CONCLUSION We identified the characteristics of articulation errors in children with adenoid hypertrophy, but our data did not show the relationship between adenoid hypertrophy and oral motor function that has been observed in previous studies. The association between adenoid hypertrophy and oral motor function remains doubtful.
