A case of congenital heminasal hypoplasia with an intranasal cyst: an extremely rare occurrence.

Various congenital nasal deformities can occur because of the complexities of the developmental process. These conditions range from partial deformities of the nose (such as isolated absence of the nasal bones, absence of columella, absence of the septal cartilage, and absence of vomeral bone) to complete absence of the nose. Congenital heminasal hypoplasia is an extremely rare defect of embryogenesis. We present a case of congenital heminasal hypoplasia with an associated dacryocystocele and intranasal cyst. The treatment of congenital dacryocystocele remains controversial. The majority of researchers recommend an initial treatment plan that does not include surgical intervention. Surgical reconstruction of the external nose and inner cavities can be delayed at least until the preschool years, when facial development is nearly complete.
