Smoking is not recommended after pituitary tumor surgery. The current surgical approach for pituitary tumors usually takes endoscopic tumor resection through the transnasal butterfly approach, which requires blocking the nostrils with medical materials such as expanding sponges in the early days after the surgery to provide compressive hemostasis of the surgical channel. Smoking may cause microvascular contracture, superimposed on some trace harmful substances contained in cigarettes, which is detrimental to wound healing as well as recovery of the area where the lesion was removed. Even in the late stages of pituitary tumor surgery, when the patient is almost fully recovered, smoking is not recommended from a health point of view. Smoking can easily lead to bronchitis, bronchitis, chronic obstructive pulmonary disease, lung cancer, cardiovascular and cerebrovascular diseases and other diseases. After pituitary tumor surgery, you should listen carefully to the medical advice of the competent doctor and cooperate with the treatment to strive for a speedy recovery.
