Results speech after palatoplasty in individuals with cleft palate

Abstract

Introduction: The primary palatoplasty to correct cleft lip and palate aims to repair the palate anatomically and functionally, to allow the proper functioning of the velopharyngeal mechanism for the acquisition of speech. However, even after the palatoplasty, 20% of the patients in average can present velopharyngeal dysfunction. Perceptual assessment of speech is the primary indicator of clinical significance of the speech symptoms. Today there is a general consensus that the protocol for surgical repair of the palate is crucial for the development of normal speech and facial growth in long term. Objective: This study aims to compare the speech results of patients with unilateral cleft lip and palate who underwent primary palatoplasty, either by the Furlow (F) or by the modified von Langenbeck (vL) techniques. Material and Methods: The sample of this study was composed of 466 patients with unilateral cleft lip and palate. Out of the total sample, 211 were submitted to primary palatoplasty by the F technique and 255 by the vL, between 9 and 18 months of age, by four surgeons. Data were collected from the Articulatory Assessment Protocol contained in the medical records of patients, with regard to the results of the Test of Nasal Air Emission, Test of Hypernasality, auditory perception judgment of speech nasality, and assessment of occurrence (presence/absence) and the type of compensatory articulation, referring to the last speech evaluation the patient was submitted at the HRAC/USP. Results: None of the compared results between surgical techniques (F vs. vL) was statistically significant (p>0.05), except the auditory perception of nasality judgment, with regard to moderate hypernasality (p<0.05). Conclusion: The hypothesis that the speech outcomes of patients operated by Furlow technique were higher than those operated by the von Langenbeck was not confirmed. Therefore, it was concluded that although both surgical techniques used in the primary palatoplasty present good results, there were not relevant to determine significant differences in the speech results.
