Bilateral congenital cholesteatoma (BCC) is rare among congenital cholesteatoma (CC) cases, and bilateral surgery poses a significant psychophysical burden on pediatric patients. Here, we present 2 pediatric cases of BCC that were successfully managed using simultaneous bilateral transcanal endoscopic ear surgery (TEES). The surgical approach provided clear visualization of the middle ear structures, enabling successful cholesteatoma removal with minimal invasiveness and a short operative time.

To address these issues, an artificial nose (heat and moisture exchanger (HME)) has been developed. However, the current HMEs do not provide sufficient physiological upper airway function.

This research aimed to elucidate the TIME of SGC and its relationship with tumor mutation burden (TMB) and to explore the rationale for the applicability of ICPi.
Materials And Methods: We selected five pathological types, namely adenoid cystic carcinoma (ACC); adenocarcinoma, not otherwise specified (ANOS); salivary duct carcinoma (SDC); and low/high-grade mucoepidermoid carcinoma (MEC).
