Nasal glial heterotopia in children: Two case reports and literature review.

Nasal glial heterotopia is a rare developmental anomaly. We present two cases of nasal glial heterotopia. The presenting symptoms, imaging findings, treatment, histological appearance, and follow-up are described in detail. We additionally reviewed all pediatric cases of nasal glial heterotopia published between 1980 and 2018 in the PubMed and Baidu Scholar databases. We identified 60 pediatric patients (36 [60%] boys). The main symptoms were nasal congestion and open-mouth breathing. Treatment was successful in all patients, and the recurrence rate was low (3/60, 5%). Nasal glial heterotopia requires multidisciplinary management but has a good prognosis.
