Summary
This study analyzed lip dimensions in 240 Nigerian children aged 0-12 years. Findings reveal age-related growth patterns and sex differences in lip anatomy, crucial for surgical planning.
Area of Science:
- Pediatric Anatomy
- Craniofacial Morphology
Background:
- Accurate anthropometric data for lip and mouth dimensions are essential for pediatric plastic surgery and orthodontics.
- Establishing normative data in diverse populations is critical for assessing developmental deviations.
Purpose of the Study:
- To determine normal lip dimensions in Nigerian children.
- To analyze the relationship between lip/mouth size and age, sex, weight, and height.
- To provide a basis for objective assessment and surgical planning.
Main Methods:
- Cross-sectional study conducted at University College Hospital, Ibadan, Nigeria (1986-1987).
- Measurements of upper vermilion arc length, mouth width, cutaneous upper lip height, and upper vermilion height in 240 children (birth to 12 years).
- All measurements taken with lips at rest.
Main Results:
- Lip dimensions showed a steady increase with age, with males exhibiting significantly larger measurements than females at specific age intervals (2-3 and 8-9 years).
- Cutaneous upper lip and upper vermilion heights demonstrated growth up to 6 years, followed by a slower growth rate.
- A linear correlation was observed between children's weight/height and lip/mouth dimensions.
Conclusions:
- Normal anthropometric values for lip and mouth dimensions in Nigerian children were established.
- Age, sex, weight, and height are significant factors influencing lip anatomy.
- These findings support objective assessment and aid in surgical planning for pediatric lip and mouth conditions.
