Congenital or Developmental, continued
Bifid Uvula
 
Bifid uvula can be an isolated finding but is often associated with a congenital submucosal cleft, which may be difficult to appreciate on examination.
 
Children with submucosal clefts may develop hypernasal speech. Children with a bifid uvula should be referred for speech therapy and an ENT evaluation if speech concerns arise.

Ranula/Mucocele
 
Mucocele: A swelling like a sac due to distension of a hollow organ or cavity with mucus.
Mucocele: A bluish or translucent cyst resulting from accumulation of mucous from trauma to a minor salivary gland. Usually located on the lower lip. Generally painless and can range from very small to several centimeters in size.
 
Ranula: Larger collection of mucous under the tongue that is unilateral. Ranulas result from blockage of a major or minor salivary duct located on the floor of the mouth.
 
Treatment: Mucoceles generally require no treatment and many resolve spontaneously. If the lesion is large or uncomfortable, excision may be warranted. In contrast, ranulas require surgical excision with marsupialization of larger lesions because they are likely to recur.

Eruption Cyst or Hematoma
 
Eruption cysts develop 1 to 3 weeks prior to eruption of a tooth. As the tooth breaks through, the fluid becomes bloody and blue or purple in color (an eruption hematoma).
 
No treatment is recommended because the cyst will resolve spontaneously when the tooth completely erupts.

Enamel: Intensely hard calcareous substance that forms a thin layer partly covering the teeth; the hardest substance of the animal body; consists of minute prisms arranged at right angles to the surface and bound together by a cement substance.

 
 
Submucosal cleft commonly accompanies a bifid uvula.
 
Spontaneous resolution is expected with a mucocele but not a ranula.
