In recent years, many researchers have investigated the various factors that can influence body posture: mood states, anxiety, head and neck positions, oral functions (respiration, swallowing), oculomotor and visual systems, and the inner ear. Recent studies indicate a role for trigeminal afferents on body posture, but this has not yet been demonstrated conclusively. The present study aims to review the papers that have shown a relationship between the stomatognathic system and body posture. These studies suggest that tension in the stomatognathic system can contribute to impaired neural control of posture. Numerous anatomical connections between the stomatognathic system's proprioceptive inputs and nervous structures are implicated in posture (cerebellum, vestibular and oculomotor nuclei, superior colliculus). If the proprioceptive information of the stomatognathic system is inaccurate, then head control and body position may be affected. In addition, the present review discusses the role the myofascial system plays in posture. If confirmed by further research, these considerations can improve our understanding and treatment of muscular-skeletal disorders that are associated with temporomandibular joint disorders, occlusal changes, and tooth loss.

Los schwannomas son tumores de naturaleza benigna o maligna, originados a partir de las células de Schwann de la vaina de mielina de nervios periféricos, autónomos y pares craneanos. Dentro de estos últimos, el nervio trigémino es el segundo en frecuencia en ser afectado. Se presenta el caso de una paciente de 33 años portadora de una neuralgia trigeminal izquierda típica de 4 meses de evolución, con un estudio imagenológico que muestra un tumor originado del nervio infraorbitario izquierdo. Se practica exéresis de la lesión, cuyo estudio histológico revela un schwannoma benigno del nervio infraorbitario. No existen casos con afectación de este nervio publicados a la fecha en la literatura internacional que se ha revisado.
Schwannomas are benign or malignant tumors that arise from Schwann cells in the myelin sheath of peripheral, autonomic or cranial nerves. Among the latter, involvement of the trigeminal nerve is usually the second in frequency. We report the case of a 33 year old patient presenting with a left trigeminal neuralgia of 4 month of evolution. The imaging study showed a tumor of the left infraorbital nerve. The lesion was excised, and the histological study revealed a benign Schwannoma of the infraorbital nerve. To our knowledge, this is the first report of this nerve being affected.

A anestesia corneana por ser uma condição rara, freqüentemente é confundida ou não diagnosticada durante o exame de rotina do segmento anterior. Relato de caso de um paciente de 18 anos encaminhado ao ambulatório de córnea e doenças externas com quadro clinico de síndrome de olho seco e com diagnóstico provável de síndrome de Sjõgren. Era amblíope de olho direito devido à opacidade corneana no eixo visual secundária a trauma com unha na infância. Foi pesquisada sensibilidade corneana que era ausente em ambos os olhos; olho seco grave e com BUT (tempo de quebra do filme lacrimal) menor que 4 segundos. Foi feito diagnóstico de anestesia corneana congênita associada a hipoestesia do nervo trigêmio pela avaliação neurológica da sensibilidade facial e movimentos bruscos do queixo que evidenciavam alterações sensoriais do nervo. O oftalmologista geral e principalmente o especialista em segmento anterior devem ter como rotina a pesquisa da sensibilidade corneana no exame do segmento anterior.
