Abstract:Abstract :Objectiv To explore the clinical features and surgical efficacy of nasal sinus adenoid cystic carcinoma. Methods The main clinical manifestations and biological characteristics of 31 patients with pathologically confirmed nasal sinus adenoid cystic carcinoma admitted from June 2010 to June 2017 in the Third People's Hospital of Yunnan Province were retrospectively analyzed, and different methods of surgery and postoperative radiotherapy were carried out for patients with different parts and stages.Results After 31 patients were followed up and one was lost to follow-up, four patients died within 3 years (survival rate was 87.1%) ,The 5-year survival rate was 70.9%.5 patients had local recurrence (recurrence rate16.2%), and a 5-year recurrence rate was 25.8%. Conclusion Nasal sinus adenoid cystic carcinoma growth site is deep, adjacent to the complex structure, tumor high invasion and along the nerve infiltration growth habit. remove tumor completely and clean by surgery is difficult, easy to recur, traditional surgery combined with nasal endoscopic skull base technology and nerve tracking technology is an effective way to reduce recurrence and improve survival rate.
