Background:
The objective of this study was to identify the characteristics and incidence of Tracheobronchial branching abnormalities in patients with microtia and to evaluate the risk of anesthesia.
Methods:
A total of 204 consecutive microtia patients and 465 nose cosmetic patients without microtia received a preoperative chest computed tomography. A retrospective study was performed with the clinical and imaging data from July 2016 to April 2017.
Results:
With the chest computed tomography images, a total of 7 cases were documented with Tracheobronchial branching abnormalities, including 6 cases among the microtia patients and 1 case among the cosmetic patients without microtia. The incidence of Tracheobronchial branching abnormalities was higher in microtia patients than the cosmetic patients without microtia (2.94% versus 0.22%, P < 0.01).
Conclusions:
The incidence of Tracheobronchial branching abnormalities was high in patients with microtia. Preoperative diagnosis of tracheal bronchus can help anesthesiologists avoid complications. Microtia with Tracheobronchial branching abnormalities may involve a new syndrome previously undiscovered or just another extension with the very wide spectrum of microtia.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
