Abstract
Objective speech evaluation such as analysis of formants 1 and 2 and nasality measurement
have been used in maxillofacial rehabilitation for outcome assessment. However, in
some patients, those evaluations are insufficient to assess a specific or unique problem.
This report describes the use of a new speech evaluation including formant 3 analysis
and voice visualization in a patient with a maxillofacial defect. The patient was
a 67-year-old man who had a maxillary defect that opened to the maxillary sinus and
who had an unnatural voice even when wearing an obturator. Nasality was low and the
frequency of formants 1 and 2 were normal even without the obturator. However, a low
frequency of formant 3 and a shifted center of voice were observed. These results
indicated that the unnatural voice was related to increased resonant volume in the
pharynx rather than hypernasality. This patient demonstrates that advanced speech
analysis can be useful for detecting the cause of speech disorder and planning maxillofacial
rehabilitation.
