**9.3 Examination of cystic fluid**

Cysts contain a fluid or semi-fluid material, which for diagnostic purposes is aspirated by the means of glass syringe and hypodermic needle. The anesthetized place where the needle is to be inserted or the bone perforated with a sterilizing agent is prepared; the area with sterile gauze should be isolated. The cystic content is then aspirated and examined on a slide or cultured [10].
