CONCLUSION
Our study showed that the application of CI in patients who underwent chemoradiotherapy for NPC is relatively safe and feasible. The long-term complications reported here, including mastoiditis, ORNTB, and REP, are not absolute surgical contraindications. MDT has an important role in the whole process of diagnosis and treatment, which can rapidly reduce the perioperative risk, effectively predict the postoperative auditory effect, and prevent the occurrence of postoperative complications.
