Congenital Heminasal Hypoplasia with an Intranasal Cyst and Its Management by Subnasal Rotation Flap

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 25-year-old lady with congenital heminasal hypoplasia associated with intranasal cyst. Computed tomography (CT) scan revealed gross septal deviation to left, rudiment left lateral wall of the nose, rudiment left external nasal framework, and intranasal cyst. Functional septorhinoplasty was done with subnasal rotation flap technique to gain airway on both sides of the nose.
