Change in nasal resonance over time: a clinical study

Fifteen of the 20 patients who had been judged by a speech pathologist and two surgeons to have had poor resonance following surgical treatment were recalled in order to review factors that may have been related to this poor result. In the present study, the poor-resonance patients were reanalyzed for present status given that they had received no further surgical intervention. The results indicate that over one-half of those patients now have normal resonance; this gives the patients who were repaired by the Cronin technique an 89 percent probability of achieving normal resonance. The age of the patient at the time of evaluation appears to be an important factor. Patients judged as "poor-resonance results" were more likely to be less than 5 years of age, but as they matured, judgment of "resonance" indicated improvement.
