Glossal double fissures in pre- and post-natal human specimens
Journal of Oral Pathology
|November 1, 1977
Summary
Double fissures on the tongue appear similarly in pre- and post-natal specimens across diverse populations. This glossal condition likely stems from underlying muscle topography rather than true fissuring.
Area of Science:
- Anatomy
- Histology
- Oral Pathology
Background:
- The prevalence and etiology of glossal double fissures are not well-understood.
- Previous studies have not extensively characterized this lingual anomaly.
Purpose of the Study:
- To investigate the occurrence and histological basis of glossal double fissures.
- To determine if the fissure appearance relates to specimen age, sex, or ethnicity.
Main Methods:
- Comparative analysis of pre- and post-natal tongue specimens.
- Cross-sectional examination of fissure morphology.
- Histological evaluation of tissue topography.
Main Results:
- Glossal double fissures were observed in similar proportions in both pre- and post-natal tongue samples.
- The condition was present across both sexes and various ethnic groups (Negro, Caucasian, mixed).
- Fissure area varied (raised, flat, depressed) and correlated with subjacent muscle bundle topography.
Conclusions:
- The double fissure appearance is likely a secondary phenomenon reflecting underlying muscle structure, not primary fissuring.
- True glossal fissuring, if present, may be an acquired condition akin to plication.
