One group will be submitted to injection snoreplasty and another group will be submitted to daily sessions of oropharyngeal exercises. Researchers involved in interventions will not participate in the outcomes evaluation and researchers responsible for the assessment of outcomes will be blinded to the tested therapeutic modalities.\n\nAll patients will be evaluated at a pre-intervention visit, when will be collected objective data and carried out a complete otorhinolaryngological exam. Patients will fill validated specific questionnaires for evaluation of snoring, apnea, daytime sleepiness, fatigue, presence of systemic arterial hypertension and sleep quality. The quality of sleep of the patients bedroom companions will be also evaluated. Patients will be randomized only after these evaluations.\n\nAll patients included in the study will be submitted to a portable sleep study. Simultaneously, the objective assessment of snoring will be held, covering the analysis of snoring intensity (measured in decibels) and the snoring index (number of snores per hour of sleep).\n\nPatients allocated to group A will receive injection snoreplasty. Patient returns will be weekly, until the complete healing of the palate. After four weeks of treatment, the bedroom companion will be asked about whether the snoring remains a problem, and if so, the procedure is repeated, with each patient receiving up to three applications. At the end of three months, all evaluations will be repeated and the data obtained will be compared to baseline data.\n\nPatients allocated at group B will be evaluated by a speech therapist. Patients will undergo weekly oropharyngeal exercises sessions under supervision, lasting about 30 minutes each, and will be instructed to perform the exercises daily at home, for a period of three months. At the end of this period, patients will be re-evaluated and the initial data will be compared to the obtained final data.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients evaluated at the Snoring and Apnea Ambulatory of Hospital de Clinicas de Porto Alegre with clinical complaints related to snoring and sleep apnea with polysomnography held within 90 days before the inclusion, evidencing index of apnea/hypopnea from 0 to 30 events per hour of sleep (snoring , mild and moderate apnea), without showing desaturation below 90% for time periods longer than 60 minutes.\n* Patient without specific prior treatment for snoring and/or apnea.\n\nExclusion Criteria:\n\n* Prior pharyngeal surgery to treat snoring or obstructive sleep apnea/hypopnea syndrome (OSAHS).\n* Body mass index above 35Kg / m2.\n* Nasal or pharyngeal anatomical obstruction higher than 50% of the light.\n* Craniofacial deformity.\n* Pregnancy.\n* Major illnesses associated.\n* Ethanol allergy history.\n* Absence of a companion to observe the intensity of snoring.\n* Patients with no ability to understand the issues (understanding of the proposed procedure and consent form).'}, 'identificationModule': {'nctId': 'NCT02568761', 'briefTitle': 'Injection Snoreplasty and Oropharyngeal Exercises', 'organization': {'class': 'OTHER', 'fullName': 'Hospital de Clinicas de Porto Alegre'}, 'officialTitle': 'Injection Snoreplasty and Oropharyngeal Exercises: Two Therapeutic Options in the Management of Snoring and Obstructive Sleep Apnea Syndrome.', 'orgStudyIdInfo': {'id': '14-0637'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Injection snoreplasty', 'description': 'Nonsurgical treatment involving the injection of 1.5 ml of 50% ethanol (1 ml of 99.5% ethanol diluted in 1ml of 2% xylocaine) into the upper palate. 0.5 ml of the solution will be implemented in three different regions of the submucosal layer of the soft palate, one median and two paramedians.', 'interventionNames': ['Procedure: Injection Snoreplasty']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Oropharyngeal Exercises', 'description': 'Weekly sessions of myofunctional exercises under the supervision of a qualified professional, lasting about 30 minutes each, combined with daily exercises without supervision for a period of three months.', 'interventionNames': ['Other: Oropharyngeal Exercises']}], 'interventions': [{'name': 'Injection Snoreplasty', 'type': 'PROCEDURE', 'description': 'Nonsurgical treatment involving the injection of 1.5 ml of 50% ethanol (1 ml of 99.5% ethanol diluted in 1ml of 2% xylocaine) into the upper palate.', 'armGroupLabels': ['Injection snoreplasty']}, {'name': 'Oropharyngeal Exercises', 'type': 'OTHER', 'description': 'Myofunctional isometric and isotonic exercises of the soft palate, pharyngeal side walls, face and tongue.', 'armGroupLabels': ['Oropharyngeal Exercises']}]}, 'contactsLocationsModule': {'locations': [{'zip': '90035-903', 'city': 'Porto Alegre', 'state': 'Rio Grande do Sul', 'status': 'RECRUITING', 'country': 'Brazil', 'contacts': [{'name': 'Caroline P Royer', 'role': 'CONTACT', 'email': 'carol_persch@hotmail.com', 'phone': '55 51 3359-8000', 'phoneExt': '8349'}, {'name': 'Simone C Fagondes', 'role': 'CONTACT', 'phone': '55 51 3359-8000', 'phoneExt': '8241'}], 'facility': 'Serviço de Otorrinolaringologia do Hospital de Clínicas de Porto Alegre', 'geoPoint': {'lat': -30.03283, 'lon': -51.23019}}], 'centralContacts': [{'name': 'Caroline P Royer', 'role': 'CONTACT', 'email': 'carol_persch@hotmail.com', 'phone': '55 51 3359 8000', 'phoneExt': '8314'}, {'name': 'Simone C Fagondes', 'role': 'CONTACT', 'phone': '55 51 3359 8000', 'phoneExt': '8241'}], 'overallOfficials': [{'name': 'Michelle Lavinsky', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Hospital de Clínicas de Porto Alegre'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'UNDECIDED'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Hospital de Clinicas de Porto Alegre', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
