    Abstract:
    INTRODUCTION: Tuberculosis (TB) in children under 15 years often results in airway compression, with bronchus intermedius (BI) being the most common site. Endoscopic enucleations can be used to remove lymph nodes and establish an airway in severe cases. Both rigid and flexible bronchoscopy are suitable, with alligator forceps being preferred for its ability to extract tissue. Recent studies have also explored cryoprobe enucleation. CASE PRESENTATION: An HIV-positive boy with persistent symptoms after 9 months of TB treatment was diagnosed based on his mother's and sister's Xpert MTB/RIF positive status. He was started on 4-drug TB treatment, but the child remained clinically symptomatic with abnormal chest X-ray and unconfirmed TB. Bronchoscopy was performed, revealing complete obstruction of BI due to caseating granulomas causing collapse of the right middle and lower lobes. Cryotherapy was used to recanalize the airway, and follow-up bronchoscopy confirmed patent BI. CONCLUSION: While cryotherapy was effective in the restoration of airway patency in this case, there is a lack of knowledge about its use in children.
