Abstract: dioelectric asymmetric brain stimulation and lingual apex repositioning in patients with atypical deglutition Original Research (10458) Total Article Views Authors: Castagna A, Rinaldi S, Fontani V, Mannu P Published Date June 2011 Volume 2011:4 Pages 209 - 213 DOI: http://dx.doi.org/10.2147/JMDH.S22830 Alessandro Castagna1, Salvatore Rinaldi1,2, Vania Fontani1, Piero Mannu1 1Rinaldi-Fontani Institute, 2School of Occupational Medicine, University of Florence, Florence, Italy Background: Atypical deglutition is exacerbated by stress and anxiety. Several therapeutic approaches have been employed to treat stress and anxiety disorders, ranging from typical psychopharmacological strategies to novel physical protocols, such as transcranial magnetic stimulation and radioelectric asymmetric conveyor (REAC) stimulation. The purpose of the present study was to test the efficacy of REAC brain stimulation in atypical deglutition. Methods: The position of the lingual apex (Payne method), pattern of free deglutition, and subjective and objective impression of deglutition were evaluated in 128 outpatients suffering from atypical deglutition. Deglutition testing consisted of an operator holding down the lower lip, hence counteracting the strength exerted by the orbicularis muscle. All subjects were treated using two REAC brain stimulation protocols. Patients were assessed before treatment, immediately after treatment, and three months following the last cycle of REAC therapy. Results: REAC stimulation led to an improvement in positioning of the lingual apex and a significant decrease of muscle involvement in all patients immediately after REAC treatment, and the improvement was maintained at three-month follow-up. Conclusion: In the present study, the REAC therapeutic protocols led to normalization in lingual apex positioning and significant improvement in swallowing in all participants suffering from atypical deglutition.

Abstract: The purpose of this research was to elucidate the relationship between tonsillar hypertrophy and Obstructive Sleep Apnea Syndrome (OSAS) in terms of cephalometric analysis, as well as to determine factors that affect OSAS severity. 25 patients were enrolled in this study. Lateral cephalograms of the subjects were taken. Disease severity was evaluated by the Apnea Hypopnea Index (AHI). Cephalometric measurements (angle between line S-N and line N-A (SNA), angle between line S-N and line N-B (SNB), distance between the Mandibular Plane and the Hyoid (MPH), posterior airway space, the width of the airway behind the base of tongue along the B-Go line (PAS), upper airway space, the distance parallel to long axis of the airway, between a horizontal plane tangent to the superior aspect of the hyoid and a horizontal plane tangent to the posterior palate (UAL), multiplication of PAS and UAL (PAS × UAL)) were analyzed and compared between the groups with and without tonsillar hypertrophy. PAS and PAS × UAL were lower in the no hypertrophy group. SNB was significantly lower in the severe apnea group than mild to moderate group in no hypertrophy group (p = 0.035). In conclusion, patients with tonsillar hypertrophy had severe obstruction, but they had a relatively larger pharyngeal space on cephalometric analysis. After exclusion of the tonsillar hypertrophy group, cephalometric analysis could be more effective for analyzing OSAS severity.

Abstract: OBJECTIVE: To compare vertical and antero-posterior ratios of facial structures, pharyngeal dimensions and of the soft palate at the sagittal plane as well as the position of the hyoid bone using lateral cephalometric radiographs in patients with Obstructive Sleep Apnoea Syndrome (OSAS) and Metabolic Syndrome (MS) and patients with OSAS without MS. SUBJECTS (MATERIALS) AND METHODS: Prospective and cross-sectional trial conducted between 2007 and 2009 at the Postgraduate Orthodontics Clinic, Aristotle University of Thessaloniki. Thirty nine patients aged between 29 and 62 years old (4 females and 35 males) with OSAS and ΑΗΙ≥30 were enrolled and assigned into two groups. The first included 19 subjects diagnosed with OSAS and MS and the second included 20 subjects diagnosed with OSAS, but with a negative diagnosis of MS. Lateral cephalometric radiographs of all subjects were obtained in Natural Head Position. The cephalometric radiographs were processed electronically and resulted in measurements regarding skeletal structures, pharyngeal dimensions, palate dimensions, and the hyoid bone position. A statistical analysis of the results was performed using Student’s t-test and the Mann Whitney test. The level of significance was set at p<0.05. RESULTS: The subjects with OSAS and MS were found to have a greater distance between the superior wall of the nasopharynx and the posterior nasal spine (PNS-SPW) (p<0.001). There were no statistically significant differences between the groups in terms of the hyoid bone position, the soft palate dimension, the antero-posterior pharyngeal dimensions, the vertical facial structure ratios and the antero-posterior maxillary position. However, in relation to mandibular position, the facial angle was found significantly increased in the group of subjects with OSAS and MS (p<0.017).CONCLUSIONS: This study compared the characteristics in lateral cephalometric radiographs of subjects with OSAS and MS and subjects with OSAS without MS and found that subjects with MS have a statistically significant greater distance between the superior wall of the nasopharynx and the posterior nasal spine, as well as a greater facial angle.

Abstract: Introduction: Two main causes of nasal airway obstruction and mouth breathing Consist: 1- anterior nasal obstruction is caused by obstruction in nasal cavity, 2- posterior (nasopharyngeal) obstruction is caused by adenoid enlargement and decreased nasopharyngeal airway. The purpose of this study was the comparison of nasopharyngeal cephalometric measurements between two groups of mouth breathing with anterior (nasal cavity) and posterior (nasopharyngeal) obstructions. Methods: In this descriptive study, a sample of 79 mouth breathers between the ages of 7 and 15 years old were selected in two anterior and posterior nasal obstruction groups. The sample had 39 patients with nasopharyngeal obstruction and mean of 10.87 years old in posterior obstruction group and 40 patients with nasal cavity obstruction without nasopharyngeal obstruction and mean of 10.97 years old in anterior obstruction group. After clinical examination by orthodontist, type of obstruction was diagnosed by ENT specialist .For each patient a lateral cephalogram was taken in centric occlusion. After tracing, 8 nasopharyngeal variables were measured and statistical t-test was conducted by calculating the mean, standard deviation and p-value of parameters. Results: In posterior nasal obstruction group, nasopharyngeal airway variables (PP, Ad.pmp and Air area) significantly decreased and nasopharyngeal bony variables (d and NP area) significantly increased. From bony nasopharyngeal measurements, mean of h, Ba.pmp and N.S.Ba variables insignificantly increased in posterior nasal obstruction group . Conclusion: We conclude that in lateral cephalometric radiography, in posterior nasal obstruction group nasopharyngeal airway measurements decrease and bony nasopharyngeal measurements increase.

Abstract: Objetivo: El presente trabajo se realizó con el propósito de describir el comportamiento de la posición del hueso hioides, en ni os respiradores bucales y no respiradores bucales. Métodos: Se recogieron historias clínicas de 60 pacientes con edad de 11 a os que acudieron a la consulta de Ortodoncia en el área de salud de la Facultad de Estomatología y nos propusimos comparar desde el punto de vista cefalométrico a un grupo de pacientes respiradores bucales, con el objetivo de determinar si existían diferencias en el comportamiento de la posición del hioides con ciertas variables cefalométricas (lineales y angulares), con respecto a pacientes no respiradores bucales (controles). Para cada una de las mediciones se calculó la media y la desviación estándar. Para determinar la posible diferencia de las mediciones para muestras independientes se realizó Prueba de t de Student para muestras independientes o su equivalente no paramétrico (Mann- Whitney y Kolmogorov- Smirnov). En todas las pruebas de hipótesis se utilizó un nivel de significación del 5 %. Resultados: El mayor número de pacientes se encuentra entre los rangos de 30-35 mm. Los valores y la frecuencia de las variables H-C3 y H-PPF tienen una distribución similar tanto en el grupo de Control como en el Grupo Respirador Bucal. La variable Gn-H muestra su mayor frecuencia en el rango de 40-45 mm. Conclusiones: Se encontró una resistencia de los músculos constrictor medio de la faringe, estilohioideo y vientre posterior del digástrico y del ligamento estilohioideo al traslado del hioides en sentido anterior, resistencia que ejercen los músculos milohioideo, genihioideo y vientre anterior digástrico en los respiradores bucales (descenso del hueso) OBJECTIVE: this paper is aimed at describing the behavior of the position of the hyoid bone in mouth- and non-mouth breathing children. METHODS: the medical histories of 60 patients aged 11 that were seen at the Orthodontics Department in the health area of the Faculty of Stomatology were collected to compare from the cephalometric point of view a group of mouth-breathing patients in order to determine if there were differences in the behavior of the position of the hyoid bone with certain cephalometric variables (linear and angular) with respect to non-mouth breathing patients (controls). The mean and standard deviation were calculated for each of the measurements. To determine the possible difference of the measurements for independent samples, the Student's t test for independent samples or their non-parametric equivalent (Mann- Whitney y Kolmogorov- Smirn

Yassaei S,Soroush MM
Journal of Dental Medicine , 2007,
Abstract: Background and Aim: Unlike other bones of the head and neck, hyoid bone has no bony articulations. It is connected to mandible, cranium and pharynx through muscles and ligaments. During treatment with functional appliance in patients with class II div1 malocclusion, mandible is positioned in inferior and anterior direction. Regarding the relation between hyoid and mandibular bone, alterations of hyoid bone position can be a result of functional appliance therapy. The aim of this study was to evaluate the changes of hyoid bone position following treatment with Farmand functional appliance in patients with class II div 1 malocclusion. Materials and Methods: In this before-after clinical trial, 28 patients with class II div 1 malocclusion which were under treatment with Farmand functional appliance for 11 months were selected. Facial growth in vertical, normal or horizontal direction was determined by cephalometric measurement. Data were analyzed with Paired-t test to compare the differences of mean values pre and post treatment. Variance analysis was used to compare the three growth patterns. P<0.05 was considered as the limit of significance. Results: Hyoid bone shifted significantly forward in horizontal dimension (P<0.01) and non-significantly upward in vertical dimension. There was no significant difference among the three studied groups with respect to hyoid bone position alterations in horizontal dimension but significant difference was observed between horizontal and vertical growth pattern in vertical dimension (P<0.05). There was significant correlation between decrease of ANB angle and forward movement of hyoid bone. Conclusion: Based on the results of this study, treatment with Farmand functional appliance (Fa II) leads to significant alterations in the position and anterior displacement of the hyoid bone.

Abstract: A 42-year-old Japanese man noticed a mass in the right submandibular region of his neck. A hard 3.0 × 2.8 cm tumor was noted on the right side of his hyoid bone. The mass was immobile and moved with deglutition.Even though radiographic studies, including positron emission tomography-computed tomography, were inconclusive, the cartilaginous tumor was surgically removed en bloc, and the tumor was diagnosed based on the results of pathological investigations. Close follow-up is recommended in such cases due to the potential for recurrences, because local recurrence occurred in 50% of the reported cases of grade one chondrosarcomas.Chondrosarcoma, a malignant tumor characterized by the production of a cartilage matrix, accounts for about 11% cases of primary malignant bone tumors [1]. The parts of the body where it develops at relatively high incidences include the long bones, the pelvis and the ribs [1]. The head and neck area are seldom affected; chondrosarcomas in this area reportedly account for 1% to 12% of all reported cases of the disease [1]. Chondrosarcoma of the hyoid bone is extremely rare, with only 15 cases being reported in international literature. Here, we describe a case of low-grade chondrosarcoma of hyoid origin. We also discuss its preoperative imaging features and its recurrence rate.A 42-year-old Japanese man noticed a mass in the right submandibular region of his neck in June 2010. He visited the department of otolaryngology at a nearby general hospital the next month and was referred for medical treatment. More than two weeks later, he visited our University Hospital. A hard 3.0 × 2.8 cm tumor was noted on the right side of his hyoid bone. The mass was immobile and moved with deglutition. No spontaneous or tender pain was noted.Laryngeal endoscopy revealed no contributory abnormal findings. Computed tomography (CT) demonstrated a gourd-shaped distension of bone in the area extending from the body of the hyoid bone to the right greater horn. A mul
