[1] [2] Cleft lip and cleft palate can often be diagnosed during pregnancy with an ultrasound exam. [1] A cleft lip or palate can be successfully treated with surgery. [1] This is often done in the first few months of life for cleft lip and before eighteen months for cleft palate. [1] Speech therapy and dental care may also be needed. [1]
However, when growth of the mandibular process is impeded, a lip pit occurs. Lip pits begin to develop on day 36. Cleft lip begins to develop on day 40, and cleft palate emerges on day 50 of development. [3] There are three types of lip pits, which are classified according to their location: midline upper, comissural, and lower lip.
Major symptoms of Hay–Wells syndrome include: sparse hair and eyelashes, missing teeth, cleft palate, cleft lip with fusing of the upper and lower eyelids, and deformed nails. [ 5 ] [ 22 ] Therefore, a diagnosis of Hay–Wells syndrome is largely based upon the physical clinical presentation of the patient.
Maxillary hypoplasia is the most common secondary deformity that results from cleft lip and cleft palate. Because of the subjective nature of the diagnosis, the incidence of maxillary hypoplasia in people with cleft lip and palate varies between 15-50%. It is estimated that 25-50% of these patients require surgical intervention. [7]
Holoprosencephaly-ectrodactyly-cleft lip/palate syndrome, also simply known as Hartsfield syndrome, is a rare genetic disorder characterized by the presence of variable holoprosencephaly, ectrodactyly, cleft lip and palate, alongside generalized ectodermal abnormalities.
These abnormalities include a cleft lip, a cleft palate which is an opening in the roof of the mouth, widely spaced eyes (hypertelorism), sharp corners of the mouth that point upward, a broad nose that can include a flattened tip, along with several deformations of both the external and middle ear structures. This syndrome is restricted to the ...
Ectrodactyly–ectodermal dysplasia–cleft syndrome, or EEC, and also referred to as EEC syndrome [1] and split hand–split foot–ectodermal dysplasia–cleft syndrome [2]: 520 is a rare form of ectodermal dysplasia, an autosomal dominant disorder inherited as a genetic trait.
A congenital lip pit or lip sinus is a congenital disorder characterized by the presence of pits and possibly associated fistulas in the lips. They are often hereditary, and may occur alone or in association with cleft lip and palate , termed Van der Woude syndrome .
