[The child with lip, maxillary, palatal cleft].
Clefting of lip, alveolus and palate may occur in multiple variations. It causes aesthetic and functional detractions. Soft palate clefts may result in hearing-, speech- and swallowing-disorders. Therefore the otolaryngologist is a very important member in the interdisciplinary team directory. A cleft-palate child belongs to an interdisciplinary consulting hour in special hospitals, where different medical specialties are involved. Most important for a sufficient medical rehabilitation are maxillofacial surgery, otolaryngology, paediatrics, plastic surgery, speech therapy, psychology and human genetics. Also many other specialties may be involved. The cleft demands a complete follow up from the child's birth until it is grown up. Hearing disorders are caused by eustachian tube disfunction. There is a high prevalence of hearing loss and middle ear diseases in cleft palate patients. Hearing losses due to middle ear effusions in the very young child. Without therapy up to 50% of the cleft palate population will develop chronic middle ear diseases with and without cholesteatomas. Early and consequent therapy with myringotomy and insertion of a tympanostomy ventilation tube is necessary and helps to avoid chronic hearing problems. There is no general accepted system of speech disorders in cleft palate patients because of the difference in shaping of the cleft and rehabilitation development. Essential for speech rehabilitation are an intact velopharyngeal system and a keen sense of hearing. Both of it is disturbed in cleft palate children. Speech disorders are treated by speech therapists with prior consultation of the interdisciplinary team. The author presents a system of primary, secondary and tertiary speech disorders in cleft palate children. Primary speech disorders are caused by faulty velopharyngeal valving, offering in hypernasality, weak plosives, fricatives and affricates. Secondary speech disorders are substitute mechanisms for plosives, nasal and pharyngeal sounds. Tertiary speech disorders are hyper- and hypofunctional dysphonias following primary and secondary speech dysfunctions.
