Six distinct patterns of tongue fissuring have been observed: plication, central longitudinal fissuring, double fissures, transverse fissures arising from a central fissure (type "A"), transverse fissures without a central fissure (type "B") and lateral longitudinal fissures. Some tongues exhibited more than one pattern. There was a significant correlation between double fissures and central longitudinal fissuring (P less than 0.002) but not between other forms of fissuring. No significant relationship was found between the occurrence of atrophic lesions and the prese-ce of fissuring. Significant differences were found between the prevalences in Xhosa and Europeans for central longitudinal fissuring, double fissures and both types of transverse fissures but not for plication. No significant differences were found between males and females and in the age distribution for those with and those without each type of fissuring. It is suggested that most tongue fissuring seen in children should be considered variations in normal anatomy rather than an abnormality.
褶皱、中央纵向裂、双裂、由中央裂产生的横向裂（“A”型）、无中央裂的横向裂（“B”型）和外侧纵向裂。有些舌头呈现不止一种模式。双裂与中央纵向裂之间存在显著相关性（P小于0.002），但其他形式的裂之间不存在显著相关性。萎缩性病变的发生与裂的存在之间未发现显著关系。科萨人和欧洲人在中央纵向裂、双裂和两种类型的横向裂的患病率上存在显著差异，但褶皱的患病率无显著差异。男性和女性之间以及有和没有每种类型裂的人群在年龄分布上均未发现显著差异。有人认为，儿童中出现的大多数舌裂应被视为正常解剖结构的变异而非异常。
