通常临床上对任何声音嘶哑超过4周的病人,一定要做喉部检查。一般用间接喉镜检查,由于功能及解剖学的原因,即使在局部麻醉情况下,也不可能做到充分检查。为了排除喉部病变,这些病人过去是在全麻情况下行直接喉镜检查。纤维导光喉镜现尚未广泛应用,然而它对于成人及大龄儿童已证明是可行的。虽然它不能检查环构部,但操作迅速、简便,避免了用直接喉镜可能产生的并发症,多数病人也无不适感,使医生有充裕的时间在静止或发音状态时检查喉部。间接喉镜与之相比没有这些优点。 1981年一架性能良好的新型Olympus纤维导光喉镜价值5000美元。住院病人一天要花费85美元,这样,如果采用纤维导光喉镜,28
Clinically, any patient who has hoarseness for more than 4 weeks must have a laryngeal examination. Indirect laryngoscopy is generally used. Due to functional and anatomical reasons, adequate examination cannot be performed even under local anesthesia. In order to rule out laryngeal lesions, these patients used to have direct laryngoscopy under general anesthesia. Fiber-optic laryngoscopes are not yet widely used, but it has proven to be feasible for adults and older children. Although it can not check the ring structure, it is quick and easy to operate, avoiding possible complications from direct laryngoscopy. Most patients do not feel uncomfortable, giving doctors plenty of time to check the throat during rest or pronunciation. Indirect laryngoscopy does not have these advantages. In 1981, a new Olympus fiber optic laryngoscope with good performance was worth US$5,000. Inpatients spend $85 a day, so if fiber-optic laryngoscopes are used, 28
