The endobronchial pattern of significant bronchial obstructive syndrome of various etiologies was analyzed in 4,000 patients with this condition. At the same time, bronchial malformations were encountered as supplementary bronchi of the left and right basal pyramids, axillary left bronchi, supplementary and displaced tracheal bronchi, and a single case of distal transposition of the right proximal bronchus in 1.58% of cases. According to the bronchoscopic findings, supplementary bronchi and transpositions of the left bronchi are the most common anatomic bronchial abnormalities (1.08%).
