Patient Q: I went to the hospital for throat discomfort and was diagnosed with mycosis fungoides, which is best treated only with surgery. But I am over 60 years old, and I am poorly and sickly, so surgery is not an option, is there a cure without surgery? What is the danger of this disease? Doctor’s Answer: Mycosis fungoides is a common type of sinusitis caused by fungal infection, mostly starting from a single sinus, with the highest incidence in the maxillary sinus, followed by the pterygoid sinus and septal sinus. It can be divided into two categories: invasive and non-invasive. Invasive cases are rare, but have a rapid onset and progression, and can invade the skull or orbit, causing serious complications, high mortality, and poor prognosis. Non-invasive is the most common type and can be divided into two types of mycobacterial sinusitis, mycobacterial ball and allergic mycobacterial sinusitis, with relatively slow progression, rarely invades the intracranial or orbital area, and has a good prognosis. This diagnosis should be non-invasive, due to the location of the butterfly sinus deep in, antifungal drugs are difficult to achieve the radical effect, and toxic side effects, the clinical use is rarely used. The first choice of treatment for this disease is surgery. Through minimally invasive nasal endoscopic surgery, the sinuses are opened and the diseased tissues are completely removed, which can achieve a very good treatment effect. Since it is a minimally invasive surgery, patients can generally tolerate it and recover quickly after the operation, and most of them can be cured by regular outpatient follow-up. Therefore, it is recommended that Ms. Jiang should be treated by surgery. If she cannot tolerate surgery, she can be treated conservatively with nasal hormone sprays, oral mucus promoters, oral nasal rinse, and other medications. However, the use of antibiotics is not recommended.
