Background: The neuromuscular activity has a critical role in the permeability of the upper airways.
Objective: The present study aimed to conduct a detailed and comparative investigation of the orofacial musculature and motor skills of children with obstructive sleep apnea (OSA).
Materials And Methods: Children aged 7 to 12 years with OSA (OSA group, n = 12) and without OSA (Control group, n = 12) were compared.
Objective: Dentofacial deformities (DFD) require orthodontic treatment, orthognathic surgery, and speech therapy for aesthetic and functional problems. This longitudinal study analyzed changes in masticatory function and three-dimensional (3D) facial soft tissue in patients with Class II and Class III DFD after orthognathic surgery. In addition, the study investigated the relationship between facial measurements, maximum bite force (MBF), and orofacial myofunctional status (OMS).

Int J Pediatr Otorhinolaryngol
November 2016
Objectives: The purposes of this study were (1) to identify possible differences in muscular and orofacial functions between children with obstructive sleep apnea (OSA) and with primary snoring (PS); (2) to examine the standardized difference between normal values of myofunctional scores and those of subjects with OSA or PS; and (3) to identify the features associated with OSA.
Methods: Participants were 39 children (mean age 8 ± 1.2 years) of which, 27 had a diagnosis of OSA and 12 had PS.
Purpose: To present the measures for tongue pressure in Brazilian young adults, considering specific tasks, and to verify the differences regarding gender and according to the tasks.
Methods: Fifty-one volunteers aged 18 to 28 years, of both genders with normal occlusion and without speech disorders were evaluated. We used the Iowa Oral Performance Instrument in the evaluation of tongue pressure (kilopascal) during specific tests of elevation, protrusion, swallowing, and lateralization, in addition to the endurance test (seconds).
Muscular and functional changes following adenotonsillectomy in children.
Int J Pediatr Otorhinolaryngol
April 2015
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.
Objective: Uvulopalatopharyngoplasty (UPPP) has been described as an option for treating obstructive sleep apnea syndrome (OSAS), with variable success rates. The main purpose of our study was to correlate UPPP success to craniofacial bony structure and orofacial muscles function.
Methods: Clinical variables, including body mass index (BMI), age, and preoperative apnea-hypopnea index (AHI); cephalometric measurements of the craniofacial region and hyoid bone position; and muscle function variables including clinical protocol and tongue strength measures were evaluated in 54 patients who underwent UPPP in the last 7years.
Unlabelled: The changes in mastication and deglutition in children with adenotonsillar hypertrophy need to be better characterized.
Objective: To evaluate the frequency of parent-reported myofunctional changes and to determine if there are differences in the alteration patterns of children with adenotonsillar hypertrophy and subjects with adenoid hypertrophy.
Method: Questionnaire and assessment by a speech therapist of children aged between three and six years with tonsillar hypertrophy.
Purpose: To verify whether the number of chewing strokes and the chewing time are influenced by dentofacial deformities in habitual free mastication.
Methods: Participants were 15 patients with diagnosis of class II dentofacial deformity (GII), 15 with class III (GIII), and 15 healthy control individuals with no deformity (CG). Free habitual mastication of a cornstarch cookie was analyzed, considering the number of chewing strokes and the time needed to complete two mastications.
Objective: To analyse the effect of integrated orthodontic treatment, orthognathic surgery and orofacial myofunctional therapy on masseter muscle thickness in patients with class III dentofacial deformity three years after orthognathic surgery.
Design: A longitudinal study was conducted on 13 patients with class III dentofacial deformities, denoted here as group P1 (before surgery) and group P3 (same patients 3 years to 3 years and 8 months after surgery). Fifteen individuals with no changes in facial morphology or dental occlusion were assigned to the control group (CG).
Background: swallowing in children with neurologic disorders.
Aim: to relate the data obtained in the clinical and in the videofluoroscopic evaluations of swallowing in children with neurologic disorders.
Methods: a retrospective analysis of 24 protocols of speech-language evaluation and of medical records of children, of both genders, referred to clinical and videofluoroscopic evaluations of swallowing at the School of Medicine of Ribeirão Preto - University of São Paulo, from January 2001 to June 2005.
Introduction: Bruxism is characterized by repeated tooth grinding or clenching. The condition can occur in all age ranges and in both genders, being related or not to other oral habits.
Objective: The objective of the present study was to investigate the occurrence of bruxism in children with nasal obstruction and to determine its association with other factors.
Objective: The objective of the present study was to determine the modifications in masseter muscle thickness before and after interdisciplinary orthodontic, oromyofunctional and surgical treatment of class III dentofacial skeletal deformities (DFSD).
Design: Fifteen patients with class III DFSD participated in the study, denoted P1 group before the interdisciplinary treatment and P2 group (same patients) 6-8 months after surgery. Fifteen individuals with no DFSD were used as the control group.
Aim: Breast-feeding promotes several benefits in childhood, among them favoring the nasal breathing. In the present study, the relationship between breathing pattern and the history of breast-feeding and of deleterious oral habits was determined.
Study Design: clinical with transversal cohort.
