Ectrodactyly-ectodermal dysplasia-clefting syndrome: the oral hygiene management of a patient with EEC

Ectrodactyly-ectodermal dysplasia-clefting syndrome (EEC) is a rare genetic disorder. EEC was first described in 1970 and occurs in 7 of 10,000 people. This paper discusses the effects of EEC and the dental complications typically associated with this syndrome. It is important for dental practitioners to be aware of EEC due to the number of dental conditions associated with it. A case report is presented to discuss the dental management, especially issues related to oral hygiene, of a patient who had EEC.

Pierre Robin sequence in a patient with ectrodactyly-ectodermal dysplasia-clefting syndrome: a case report and review of the literature

Ectrodactyly-ectodermal dysplasia-clefting (EEC) syndrome is a rare condition first identified in 1970. The majority of cases are reported to be autosomal dominant with variable expression and penetrance. The most common clinical feature is ectodermal dysplasia. Ectrodactyly, cleft lip with or with out cleft palate and urogenital anomalies are also main clinical features of EEC syndrome. Pierre Robin (PR) sequence has the clinical findings of micro-retrognathia, retroposed tongue (glossoptosis), cleft of the secondary palate, and upper airway obstruction. Etiologically PR sequence is heterogeneous. It has been reported that less than 20% of cases are isolated, non-syndromic PR sequence. We present a case of a newborn male who was referred to our craniofacial clinic with EEC syndrome and PR sequence. This case represents a unique clinical association. We found no other reports in the literature of these two clinical entities occurring together. Upper airway obstruction of PR sequence, secondary to glossoptosis and micro-retrognathia, gives this association clinical relevance. In addition, this clinical association may represent a new gene locus associated with EEC syndrome.
