As the anatomic variations among Turkish population have not been studied previously, we aimed to evaluate the type and frequency of tracheobronchial variations (TBVs) in our bronchoscopy population. In a 3\u2010year period, 1,114 patients underwent flexible bronchoscopy (FB). Among these, 780 (70%) were male. The mean age of the patients was 51.3 \u00b1 15.1 (range: 17\u201384) years. In 639 cases, no TBV were detected. A total of 999 TBV were observed in 475 patients. Of all, 71.3% (713) of the total TBV were detected in males. Forty\u2010nine and six\u2010tenths percent (49.6%) of the TBV were observed on the right bronchial system, 49.2% on the left, and 1.2% in the trachea. The five most frequently observed TBV were right lower lobe basal orifice with two subsegments, left lower lobe basal orifice with two subsegments, left upper lobe with three segments, right upper lobe with two segments, and right lower lobe with a subapical segment. In the same lobe bronchus, single variation and two different TBV were seen in 85% and 15% of patients, respectively. Number of TBV increased linearly with the number of lobes involved. The availability and popularity of FB in recent years has led to the increase in identification and reporting of TBV. TBV should be correctly identified and documented. This information is invaluable during follow\u2010up bronchoscopies as well as lung resection. Clin.
