Objective: Previous worldwide popular Nasometer (such as Nasometer II 6450) requires tight contact between the plate and the philtrum of patient that restricts natural oral movement. The Smart Naso was developed with the desiration to provide clinician with more comfortable and affordable device. Therefore, the present study was conducted to evaluate the usefulness of this new device.
Methods: Two cleft palate patients were measured nasalance using both Nasometer II 6450 and Smart Naso. Besides, repetitive measurements with one-week interval and by two examiners were performed for Smart Naso to assess its intra-rater and inter-rater reliability. Speech materials including /a/, /i/, /papapapapapa/, /mamamamamama/, and oral phrase were used. Nasalance results measured using two devices, by two examiners and two measurements with one-week interval were compared each other.
Results: Applying Smart Naso for nasalance measurement in two patients showed similar results to Nasometer II 6450 (First patient: 12.5 and 11 for /a/, 13.5 and 14 for /i/, 11.5 and 12 for /papapapapapa/, 30.5 and 40 for /mamamamamama/, 15.6 and 10 for oral phrase; Second patient: 60.5 and 61 for /a/, 74.4 and 93 for /i/, 53.9 and 62 for /papapapapapa/, 72.2 and 68 for /mamamamamama/, 62 and 74 for oral phrase). Repetitive measurement with one-week interval by the same examiner using Smart Naso showed similar scores (First patient: 12.7 and 12.5 for /a/, 25.8 and 13.5 for /i/, 11 and 11.5 for /papapapapapa/, 22.1 and 30.5 for /mamamamamama/, 17.2 and 15.6 for oral phrase; Second patient: 73.5 and 60.5 for /a/, 62.4 and 74.4 for /i/, 69.6 and 53.9 for /papapapapapa/, 76 and 72.2 for /mamamamamama/, 69.7 and 62 for oral phrase). There were also similarity between results of two examiners using Smart Naso (First patient: 12.5 and 12.3 for /a/, 13.5 and 17.5 for /i/, 11.5 and 6.3 for /papapapapapa/, 30.5 and 23.9 for /mamamamamama/, 15.6 and 15.8 for oral phrase; Second patient: 60.5 and 62.4 for /a/, 74.4 and 70.4 for /i/, 53.9 and 56.5 for /papapapapapa/, 72.2 and 65.9 for /mamamamamama/, 62 and 62.6 for oral phrase).
Conclusions: The developed Smart Naso showed similar nasalance results to Nasometer II 6450. There were similarity in results of repetitive measurements with one-week interval and by two examiners using Smart Naso. More cleft patients are needed to assess the reliability and validity of this new device in nasalance measurement.
