Treatment
The dental treatment included root canal treatment, composite restorations, extractions and removable prostheses. This paper highlights features of Rapp-Hodgkin Syndrome and its dental rehabilitation. [ncbi.nlm.nih.gov]
The focus of our treatment was to restore the function and esthetics. However, this should not underestimate the importance of prevention. Age and psychological aspect governed our treatment. [jisppd.com]
Prognosis
Prognosis - Rapp-Hodgkin syndrome Not supplied. [checkorphan.org]
Prognosis This syndrome is rare and has only recently been delineated, so it is difficult to find any reliable information on long-term outlook. Patients who are adequately managed seem to do well in the medium term. [patient.info]

Etiology
(Etiology) Rapp-Hodgkin Syndrome is a genetic disorder that is caused by mutations in the TP63 gene The condition is inherited in an autosomal dominant manner Autosomal dominant: Autosomal dominant conditions are traits or disorders that are present when [dovemed.com]

Pathophysiology
Pathophysiology Ectodermal dysplasia results from the abnormal morphogenesis of cutaneous and/or oral embryonal ectoderm (ie, hair, nails, teeth, eccrine glands). In some forms, mesodermal abnormalities are also present. [emedicine.medscape.com]
The following are the 3 most commonly recognized entities: EEC (ectodermal dysplasia, ectrodactyly, cleft lip/palate) syndrome Rapp-Hodgkin syndrome Hay-Wells or AEC (ankyloblepharon, ectodermal dysplasia, cleft lip/palate) syndrome Pathophysiology: ED [doctors.co.il]
In 2003, Lamartine reclassified ED into the following 4 functional groups based on the underlying pathophysiologic defect: (1) cell-to-cell communication and signaling (2) adhesion (3) development (4) other 27. The most common ectodermal [de.slideshare.net]
Prevention
Topical management of the recurring external otitis slows the process but has been unsuccessful in preventing restenosis of both external auditory canals. [ncbi.nlm.nih.gov]
