RESUMO
OBJECTIVE: Cleft palate increases the risk of chronic middle ear disease and hearing loss. The goal of this report was to determine which of two palate surgeries and which timing of palate surgery were associated with better otologic and audiologic outcomes in children with unilateral cleft lip and palate at 5 to 6 years of age. DESIGN: Subjects were randomly assigned to the von Langenbeck with intravelar veloplasty or Furlow palate repair, to palate surgery at 9 to 12 months or 15 to 18 months of age, and to the Spina or Millard lip repair. SETTING: Centralized, tertiary care craniofacial treatment center. PATIENTS: A total of 673 infants with unilateral cleft lip and palate. INTERVENTIONS: Palate and lip were repaired using established techniques. Serial otoscopic and audiometric evaluations were performed. MAIN OUTCOME MEASURES: Hearing and otoscopic findings at 5 to 6 years old. RESULTS: There were 370 children available for analysis. Hearing and need for tympanostomy tube placement did not differ by palatoplasty, age at palatoplasty, cheiloplasty, or surgeon. Risk of developing cholesteatoma or perforation was higher with Millard cheiloplasty (odds ratio â=â 5.1, 95% confidence interval â=â 1.44 to 18.11, p â=â .012). Type and age at palatoplasty were not significantly associated with either the rate of developing these sequelae or the rate of achieving bilaterally normal hearing and ear examinations. CONCLUSIONS: Type of palatoplasty did not influence otologic and audiologic outcomes in 5- to 6-year-olds with unilateral cleft lip and palate. The potential influence of lip repair on otologic outcomes warrants further investigation.

OBJECTIVE: The obturating pharyngeal flap used in correcting velopharyngeal insufficiency has been implicated in creating difficulty in nasal breathing for some patients and/or in causing hyponasal speech, obstructive sleep apnea, and snoring. This is a case report of an individually designed removable prosthesis that positions an acrylic tube through each port lateral to the pharyngeal flap, with the goal of preventing the collapse of the ports during sleep and the consequent snoring. DESIGN: The acrylic tubes maintain an opening through both lateral ports preventing the soft tissues of the lateral walls from vibrating against the pharyngeal flap (causing the snoring sound) and allowing nasal breathing. RESULTS: The acrylic tubes effectively eliminated the patient's problem of snoring. CONCLUSIONS: This case study demonstrates that snoring associated with a pharyngeal flap can be controlled prosthetically by maintaining an opening through the two lateral ports, preventing the soft tissues of the walls of the lateral ports from vibrating against the flap.

OBJECTIVE: The purpose of this study was to evaluate the effect of nasal decongestant on nasalance scores for a group of 100 individuals. PARTICIPANTS: Forty-one subjects with hypernasality and 59 subjects without hypernasality underwent nasometric assessment at the Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo, Bauru, Brazil. DESIGN: Nasalance scores were obtained for each subject before the application of a nasal decongestant and again 10 minutes after subjects received a topical nasal decongestant applied into both nostrils. RESULTS: The nasalance scores obtained after the application of the nasal decongestant were significantly higher than those obtained before the decongestant. CONCLUSIONS: Nasal decongestion had a small but statistically significant effect on nasalance scores, suggesting that in some individuals, nasal congestion should be a variable of concern when using the Nasometer. Both nasal congestion (i.e., due to nasal rhinitis) and the effects of nasal decongestant sprays may influence Nasometer test results. Interpretation of nasalance scores, therefore, should be done carefully. Furthermore, nasometry, with and without nasal decongestant, can be a valuable clinical tool for screening anterior nasal obstruction, helping to isolate obstruction due to nasal congestion from structural obstruction in the nasal cavities.

OBJECTIVE: To determine the immediate and longer-term effect(s) on tongue movement following the placement of an experimental opening through a palatal obturator (replicate of subject's prosthesis) worn by an adult male with an unrepaired cleft of the hard and soft palate. METHODS: Tongue movements associated with an anterior experimental opening of 20 mm(2) were examined under three conditions: a control condition in which the subject wore the experimental obturator completely occluded, a condition immediately after drilling the experimental openings through the obturator, and a condition after 5 days in which the subject wore the experimental obturator with the experimental opening. An Electromagnetic Articulograph was used for obtaining tongue movements during speech. RESULTS: The findings partly revealed that the immediate introduction of a perturbation to the speech system (experimental fistula) had a temporary effect on tongue movement. After sustained perturbation (for 5 days), the system normalized (going back toward control condition's behavior). Perceptual data were consistent with kinematic tongue movement direction in most of the cases. CONCLUSIONS: Although the immediate response can be interpreted as indicative of the subject's attempts to move the tongue toward the opening to compensate for air loss, the findings following a sustained perturbation indicate that with time, other physiological adjustments (such as respiratory adjustments, for example) may help reestablish the requirements of a pressure-regulating system.
