Long-Term Hypernasality and Nasalance Scores After Intravelar Veloplasty for VPI

60 patients with repaired cleft palate and residual velopharyngeal insufficiency were analyzed before and after secondary palatoplasty with intravelar veloplasty. The dataset includes perceptual hypernasality ratings on a 6-point scale and nasalance scores from nasometry, assessed pre-surgery and an average of 16 months post-surgery. The data was collected by Renata Paciello Yamashita to investigate the long-term effectiveness of the surgical procedure.

Use Cases

• Modeling the relationship between surgical intervention and hypernasality reduction based on pre- and post-operative perceptual scores.
• Predicting nasalance normalization outcomes based on patient characteristics and baseline nasalance scores.
• Analyzing the long-term efficacy of intravelar veloplasty for VPI management using longitudinal clinical assessment data.

Strengths

• Includes data from 60 patients with a defined age range of 4 to 52 years.
• Provides longitudinal data with assessments conducted an average of 16 months apart.
• Uses standardized clinical measures: a 6-point perceptual scale for hypernasality and a 27% nasalance cutoff score.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
• Data may reflect geographic and linguistic bias inherent to the study's use of Brazilian Portuguese sentences.

Collection Method

Clinical study involving perceptual speech assessment and nasometry on patients undergoing surgery.

Time Range

Assessments were done 4 days before and an average of 16 months after surgery.

Geography

Likely Brazil, given the use of Brazilian Portuguese sentences for assessment.
