“…TB is reported to be located about 2-6 cm superior to carina in the literature. [2,[5][6][7][8] In our study distance of TB from carina was analyzed within each type ( Table 2). This data provides a contribution to literature.…”

“…Tracheal bronchus (TB) is a congenital anomaly which is usually located at the junction of the mid and distal thirds of trachea on the right lateral wall. [1,2] It originates from trachea or either from the main bronchus and it is directed to the upper lobe of the lung. [3] Tracheal bronchii are commonly seen on the right side but can also be seen on the left side or rarely seen bilaterally.…”

“…[2,[5][6][7][8] It typically originates from lateral wall of trachea or from the main bronchus. [2,5] Even if they originate from different parts of the airway tree its' direction is the upper lobe. [5] There are three types of TB described; displaced type, supernumerary type and true 'pig' bronchus type.…”

“…Entire right upper lobe bronchus is displaced to trachea from right main bronchus in the true bronchus type. [2,6] Levin et al [2] reported the displaced type (18%) to be the most common one. In the present study we aimed to recognize and classify the TB in our population.…”

“…[5] There are three types of TB described; displaced type, supernumerary type and true 'pig' bronchus type. [2,8] These subdivisions are based on the branching patterns of the right upper lobe bronchus. In the displaced type right upper lobe bronchus bifurcates and anomalous bronchus (apical segment) arises from trachea.…”

Amaç: Bu çalışmanın amacı, popülasyonumuzdaki Trakeal Bronkusları (TB) tespit etmek ve sınıflandırmaktır. Gereç ve Yöntem: Bu retrospektif çalışmaya farklı nedenlerle torasik BT çektiren toplam 1500 hasta dahil edildi. 12 bireyde TB tespit edildi. TB'li 12 hastanın; beşi erkek, yedisi kadındı. TB prevalansı %0,8 bulundu. Kadınlarda (% 58,3) erkeklerden (% 41,7) daha sık tespit edildi. Bulgular: TB'lu 12 bireyin yedisinde displaced tip (% 58.3), ikisinde supernumarary tip (% 16.7) ve üçünde pig tip (% 25) bronkus vardı.Displaced tip kadınlar arasında en yaygın olanıdıydı. Beş erkekten ikisinde displaced tip, ikisinde pig tip, birinde supernumerary tip görüldü. Cinsiyet ve tip arasındaki ilişki istatistiksel olarak anlamlı bulunmadı (p = 0.516). TB'nin ortalama çapı 5.24 ±1.53 mm idi. Displaced ve pig bronkus tipleri arasındaki çapa göre fark istatistiksel olarak anlamlıydı (p = 0,017). Bu çalışmada ayrıca carina ve TB arasındaki mesafe de ölçüldü. Displaced tip ile pig bronkus tiplerinin carina'ya olan mesafeleri açısından fark yoktu (p = 0.067).Sonuç: TB'nin tanınması endotrakeal entübasyonda kritik öneme sahiptir. TB, tüpün yan yüzü tarafından tıkandığında, lob kollapsa uğrayabilir. Diğer yandan, yanlışlıkla entübe edildiğinde, aşırı havalanma sonucu pnömotoraks oluşabilir. Abstract ÖzEmre Can ÇELEBİOĞLU1, Selma ÇALIŞKAN2, Sinem AKKAŞOĞLU2, Hilal Göktürk Nakkaş3, İbrahim Tanzer SANCAK4Aim: The aim of the study recognize and classify the Tracheal Bronchus (TB) in our population. Material and Method:A total of 1500 patients who underwent thoracic Computed Tomography (CT) examination for different reasons were enrolled in this retrospective study. 12 patients with TB were reported. Of the 12 patients with TB; five were males and seven were females. Prevalence of TB was found to be 0.8%. It was indicated more frequently in women (58.3%) than in men (41.7%). Results:Of the 12 patients with TB seven had displaced type (58.3%), two had supernumerary type (16.7%) and three had pig bronchus (25%). Displaced type was most common among the females. Of the five males two had displaced type, two had pig bronchus and one had supernumerary type. Relation between gender and type was not found to be statistically significant (p=0.516). The mean diameter of the TB was 5.24±1.53 mm. Difference between displaced and pig bronchus types according to diameter is statistically significant (p=0.017). Distance between carina and TB was also measured in the present study. There was no difference between displaced type and pig bronchus type according to distance from carina (p=0.067). Conclusion:Recognizing the TB is critically important during endotracheal intubation. When the TB is occluded by the side of the tube the lobe may collapse. On the other hand when it is mistakenly intubated, over aeration may lead pneumothorax.

The optimal treatment for tracheal tumors necessitates sequential tumor elimination and tracheal cartilage reconstruction. This study introduces an innovative inorganic nanosheet, MnO2/PDA@Cu, comprising manganese dioxide (MnO2) loaded with copper ions (Cu) through in situ polymerization using polydopamine (PDA) as an intermediary. Additionally, a specialized methacrylic anhydride modified decellularized cartilage matrix (MDC) hydrogel with chondrogenic effects is developed by modifying a decellularized cartilage matrix with methacrylic anhydride. The MnO2/PDA@Cu nanosheet is encapsulated within MDC‐derived microneedles, creating a photothermal‐controllable MnO2/PDA@Cu‐MDC microneedle. Effectiveness evaluation involved deep insertion of the MnO2/PDA@Cu‐MDC microneedle into tracheal orthotopic tumor in a murine model. Under 808 nm near‐infrared irradiation, facilitated by PDA, the microneedle exhibited rapid overheating, efficiently eliminating tumors. PDA's photothermal effects triggered controlled MnO2 and Cu release. The MnO2 nanosheet acted as a potent inorganic nanoenzyme, scavenging reactive oxygen species for an antioxidant effect, while Cu facilitated angiogenesis. This intervention enhanced blood supply at the tumor excision site, promoting stem cell enrichment and nutrient provision. The MDC hydrogel played a pivotal role in creating a chondrogenic niche, fostering stem cells to secrete cartilaginous matrix. In conclusion, the MnO2/PDA@Cu‐MDC microneedle is a versatile platform with photothermal control, sequentially combining antitumor, antioxidant, pro‐angiogenic, and chondrogenic activities to orchestrate precise tracheal tumor eradication and cartilage regeneration.
