Role of Passavant's ridge in cleft palate speech.

In order to reevaluate the role of Passavant's ridge, 10 adult cleft palate patients with a marked ridge were examined by a radiographic and cineradiographic method. Following results were obtained: 1. Height of the ridge varies with the vowels. 2. Height of the ridge in consonant syllable phonation is not related to velopharyngeal closure required for each consonat but to the succeeding vowels. 3. Tongue position for vowel phonation has a great effect on the appearance of the ridge. In conclusion, formation of Passavant's ridge is not associated with the degree of velopharyngeal closure necessary for the specific speech sound, but it closely related to the tongue position for vowel production. Thus the significance of Passavant's ridge in cleft palate speech remains quite doubtful.

Hearing in cleft palate patients.

Permanent hearing loss is present in more than 50% of the adult cleft palate population. Serous otitis media related to eustachian-tube dysfunction is present from birth in over 90% of infants with cleft palates and leads to middle ear changes responsible for permanent hearing loss in adulthood. Early and successful closure of the cleft palate is associated with decreased adult hearing loss and secondary surgery for hypernasal cleft palate is also associated with a decreased incidence. Hard-of-hearing patients have a tendency to remain more hypernasal than their normal-hearing peers and are less likely to respond to conventional speech therapy.

Accelerated Healing of The Wider Lateral Defects in Adult Cleft Palate Repairs

Background: Adult primary palatoplasty is more challenging tha n in infants because the gaps are wider. The risk ofintraoperative bleeding and palatal fistula are higher. Most adults with un-operated palatal cleft have good maxillary growth but poor speech. The aim of this study is to introduce our technique in repairing wide cleft palate in adult patients. Patients and Methods: We report four patients with cleft palate who underwent palatoplasty at adulthood. The age ranges from 17 to 20 years. Interspina distance were between 2 to 3.5 cm. All of them were nonsyndromic and had normal maxillary growth. The surgical technique used on these patients was two-flap palatoplasty with an additional 3 mm gingival bulk on the lateral side of the flap. Honey was given as oral drops postoperatively. Result: Lateral palatal defect healed well and epithelialized completely between 7 -14 days postoperative and only one small palatal fistula was found with this modified technique. All subjects had good maxillary growth, and speech outcome was poor to begin with.Summary: Two-flap palatoplasty can adequately provide palatal closure, especially with an additional lateral flap extension to include gingival components. This extension widens the flaps and aid palatal closure by not leaving lateral defects too wide.

Auditory assessment of cleft palate adults.

The study was designed to obtain data relative to hearing level and discrimination in cleft palate adults. The results indicated that the subjects as a group have hearing levels within normal limits and that their auditory discrimination is normal. Furthermore over 50% of the subjects showed evidence of previous middle ear infection. However, there were only two cases of active middle ear pathology. The findings suggests that middle ear infection in cleft palates runs its course before adolescence.

The application of the principles of cephalometric laminagraphy to studies of the frontal planes of the human head

1. 1. Laminagraphy is explained and applied with existing cephalometric techniques to produce cephalometric laminagrams. 2. 2. The apparatus requisite to the production of cephalometric laminagrams may be classified in two principal groups: (1) essential apparati and (2) accessory instruments. The essential apparati comprise: 2.1. 1. Laminagraph with tube furnishing relatively small (1.5 mm.) focal spot and standard energizing apparatus with its control panel. 2.2. 2. Headholding device. 2.3. 3. Projection scale and accurate rules. 2.4. 4. Head measuring calipers. 2.5. 5. X-ray films and equipment for processing them. The accessory instruments comprise: 2.1. 1. Horizontal tracing table or viewing box. 2.2. 2. Fine pointed dividers. 2.3. 3. Drawing instruments. 2.4. 4. Tracing film. 2.5. 5. Miscellaneous adjuncts. 3. 3. A critical test was conducted upon the laminagraph to evaluate the accuracy with which the focal plane may be selected and to determine the thickness of the focal plane rendered. 4. 4. The material upon which this investigation was conducted comprised: 4.1. 1. Infant material from the Pediatrics Department, Research and Educational Hospital, University of Illinois, Chicago, Illinois. 4.2. 2. Normal adult material volunteered by the graduate students of the Department of Orthodontics, University of Illinois, class of 1948. 4.3. 3. An adult cleft palate was volunteered by one of the author's patients. 5. 5. Laminagraph exposure factors are enumerated and described: 5.1. 1. Factors unique to laminagraphy. 5.2. 2. Conventional exposure factors as employed in laminagraphy. 6. 6. Measurements were made of certain dental structures in laminagraphic projection utilizing a projected scale. Actual measurements of the same structures were taken upon dental casts of the same individuals. These measurements were compared to determine the accuracy of this method for cephalometric purposes. 7. 7. Suggestion is offered pertinent to the standardization of apparatus positioning, of patient positioning, and of exposure technique so as to make practicable the application of cephalometric laminagrams to longitudinal investigations on the growth of the human head. 8. 8. The detailed technique for producing cephalometric laminagrams was given in summation.
