Removal is usually achieved via anterior rhinoscopy or endoscopy, although a lateral rhinotomy approach has been required in select cases in which complete removal through the nostrils or the posterior choanae
was not possible due to the large size of the mass (13).

Emily was born with CHARGE (coloboma--a cleft, slit, gap, or fissure of the eye; heart defects; atresia of the choanae
