Ngoku usebenza kutyando lwentloko nentamo kwiSibhedlele soMhlaza saseBeijing. Usebenze kutyando lwentloko nentamo kangangeminyaka engama-30 kwaye uqokelele amava amaninzi ezonyango. Ugqibe phantse ii-10,000 zotyando kuzo zonke iintlobo zeethumba zentloko nentamo, kwaye ulungile kuzo zonke iintlobo zonyango lotyando lweethumba zentloko nentamo, ngakumbi kwiithumba ezinobungozi ze-thyroid. Unyango lweentlobo ezahlukeneyo zomhlaza we-laryngeal lunesifundo esinzulu ngakumbi, ukuze ukuxhaphaka kweengxaki kutyando lwe-thyroid kuncitshiswe ukuya kwi-0.1%, kwaye izinga lokusinda kweminyaka eli-10 lomhlaza we-thyroid lingaphezulu kwama-90%. Izinga lokusinda kweminyaka emi-5 lomhlaza we-laryngeal yi-75%, kwaye ama-70% ezigulana ezinomhlaza we-laryngeal zinokubuyisela umsebenzi wazo wokuphefumla nowokuthetha emva kokususwa. Inokwenza ngobuchule ukulungisa nokwakha kwakhona iziphene ezahlukeneyo emva kokususwa kweethumba zomlomo neze-maxillofacial (ezifana nomhlaza wolwimi, umhlaza womlomo ophantsi, ithumba le-maxillary ne-mandible, umhlaza womlomo, i-buccal mucosa, njl.njl.). Amaphepha ezonyango angaphezu kwama-30 apapashwe kwiijenali eziphambili zelizwe. Ngokunyuka kokusetyenziswa konyango olupheleleyo lomhlaza wentloko nentamo ophucukileyo, umgangatho wobomi kunye nenqanaba lokusinda kwezigulane ezinomhlaza wentloko nentamo kuye kwaphucuka kakhulu.

Unobuchule kuzo zonke iintlobo zonyango lotyando lweethumba zentloko nentamo, ingakumbi kwiithumba ezinobungozi ze-thyroid kunye neentlobo ezahlukeneyo zomhlaza we-laryngeal.
