Objective This study uses polysomnography and the Epworth sleepiness scale to assess the efficiency of the Ocluch©MAD in patients with Obstructive sleep apnea-hypopnea syndrome (OSAS), on overall respiratory disturbance indices (RDI), supine respiratory disturbance index (SRDI), minimum oxygen saturation, microarousals, CT90 (or ID90), sleep efficacy and snoring. These data are associated with skeletal class and facial biotype in order to establish predictive parameters for its effectiveness according to craniofacial morphology. Methods 22 adult patients (between 38 and 60 years of age) of both sexes (7 women, 15 men) diagnosed with OSAS in the Hospital de Carabineros de Chile (HOSCAR) Neurology Unit were recruited and given the Ocluch© MAD in the hospital's dental clinic, for its use during a three-month period. Patients were assess at the beginning and in the end of this period. Results 87.5% of patients with mild OSAS achieved the success criterion and normalization; 71.5% of patients with moderate OSAS achieved the success criterion and 33.3% achieved normalization; 85.7% of patients with severe OSAS achieved the success criterion and 57.1% achieved normalization. All class I and mesofacial patients achieved normalization, but class II patients had the greatest proportional improvement. Conclusions The Ocluch MAD is an efficient low-cost alternative that should be considered among the therapeutic arsenal for a multidisciplinary approach to treating this disease.

ResumenObjetivoPara el manejo de los trastornos temporomandibulares y del bruxismo de sueño (BS) se ha recurrido durante años a los dispositivos oclusales rígidos superiores (DORS). Estos dispositivos podrían modificar la posición de la mandíbula induciendo una posición más posterior de la lengua y del hueso hioides, comprometiendo la permeabilidad de la vía aérea superior y agravando los trastornos respiratorios del sueño. Este trabajo tiene como objetivo evaluar el cambio de las dimensiones lineales y de área de la luz de la vía aérea faríngea en pacientes diagnosticados con BS que estén usando un DORS, mediante una telerradiografía lateral.MetodologíaSe reclutaron 20 pacientes del Hospital de Carabineros, de ambos sexos, diagnosticados con BS probable manejados con un DORS, a los cuales se les tomó una telerradiografía lateral sin DORS y otra con DORS sin modificar la postura para evitar distorsiones por posición craneocervical. Se analizó el área y profundidad faríngea por medio de cefalometría para medir el espacio faríngeo.ResultadosSe observaron diferencias estadísticamente significativas en la disminución del área de la orofaringe (promedio: 41,2mm2, p=0,035) y la profundidad al nivel del gonion (promedio: 0,38mm, p=0,019) y la úvula (promedio: 1,38mm, p=0,009). No se encontró correlación entre el aumento de la dimensión vertical y las diferencias dimensionales.ConclusiónBajo las condiciones de este estudio el uso de un DORS produce una tendencia a la disminución del área y profundidad orofaríngea.AbstractObjectiveThe use of the superior rigid occlusal splint (SROS) has been used to management temporomandibular disorders and sleep bruxism for many years. These SROS could change the mandibular position leading to a more posterior position of the tongue and hyoids bone, and compromising the upper airway flow permeability and make sleep-breathing disorders worse. The aim of this study is to evaluate the linear and area changes of lumen in patients with sleep bruxism who are using a SROS, measured by lateral teleradiograph.MethodologyThe study included 20 patients, of both sexes, from the Hospital de Carabineros, Chile, who were diagnosed with probable sleep bruxism due to using and SROS. The cephalometric analysis was performed of the area and pharyngeal depth in order to measure the pharyngeal space, by obtaining a lateral teleradiograph without SROS and a second teleradiograph using SROS, at the same time, to avoid dimensional variation due to possible craniocervical positional changes.ResultsA statistical significance was found for oropharynx reduction (mean: 41.2 mm2, P=.035), for the gonion linear depth (mean: 0.38mm, P=.019), and at uvula level (mean: 1.83mm, P=.009). No correlations were found between the increasing vertical dimensions using SROS and pharyngeal spaces.ConclusionThe using of a superior occlusal splint (SROS) could reduce the oropharyngeal depth and space.

La microsomía hemifacial corresponde a la segunda malformación congénita en prevalencia, luego de la fisura labiopalatina, y se describe como una alteración congénita del primer y el segundo arcos branquiales. El síndrome de Goldenhar tiene características típicas de la microsomía hemifacial, con la adición de dermoides epibulbares y anomalías vertebrales. Ambas patologías presentan características de expresión variable y por tanto los tratamientos son acordes a su individualidad. En esta revisión de tema se analizan su etiología, clasificaciones, características y tratamiento., Hemifacial microsomia is the second congenital malformation in prevalence, after cleft lip and palate, and is described as a congenital alteration of the first and second branchial arches. Goldenhar syndrome has typical characteristics of hemifacial microsomia with the addition of epibulbar dermoids and vertebral anomalies. Both pathologies have variable expression’s characteristics and therefore the treatments are according to their individuality. In this review of the topic is analyzed the etiology, classifications, characteristics and treatment.

RESUMEN: La fisura labio palatina (FLP) es una alteración del desarrollo, congénita, de etiología desconocida. La fístula oronasal es la complicación más común de la reparación del paladar con fisura. Los problemas más comunes incluyen hipernasalidad al hablar y el pase de fluidos y comida hacia la cavidad nasal. El caso corresponde a un paciente de 16 años de edad, sexo masculino, con fístula buconasal de 2,1 cm de diámetro mayor en sentido transversal, como secuela de FLP unilateral derecha. Además relata problemas en la alimentación, traspaso de fluidos a la cavidad nasal, problemas de habla por insuficiencia velo faríngea (IVF) valor 9, alteraciones en sus relaciones interpersonales y baja autoestima. Se realizó el injerto de lengua en fístula buconasal, tratamiento de ortodoncia y rehabilitación oral para dar solución estética y funcional. El éxito del tratamiento integral le permitió al paciente mejorar sus relaciones sociales debido a una mayor autoestima.
