Mohs surgery is also used for squamous-cell carcinoma, melanoma, atypical fibroxanthoma, dermatofibrosarcoma protuberans, Merkel cell carcinoma, microcystic adnexal carcinoma, and multiple other skin cancers; usually with cure rates higher than for other surgical and non-surgical treatments.An  essential aspect of Mohs surgery is that the Mohs surgeon performs the surgery and personally reviews the Mohs pathology slides. Most standard excisions done in an office setting are sent to an outside laboratory for standard bread loafing method of processing. With this method, it is likely that less than 5% of the surgical margin is examined, as each slice of tissue is only 6 micrometres thick, about 3 to 4 serial slices are obtained per section, and only about 3 to 4 sections are obtained per specimen. Cryosurgery
Cryosurgery is an old modality for the treatment of many skin cancers. When accurately utilized with a temperature probe and cryotherapy instruments, it can result in very good cure rate. Disadvantages include lack of margin control, tissue necrosis, over or under treatment of the tumor, and long recovery time. Overall, there are sufficient data to consider cryosurgery as a reasonable treatment for BCC. There are no good studies, however, comparing cryosurgery with other modalities, particularly with Mohs surgery, excision, or electrodesiccation and curettage so that no conclusion can be made whether cryosurgery is as efficacious as other methods. Also, there is no evidence on whether curetting the lesions before cryosurgery affects the efficacy of treatment.
Nafcillin 1.5 g IV q4h
Cefotaxime 1.5 to 2 g IV q4h
Metronidazole 15 mg/kg load followed by 7.5 mg/kg IV q6hVancomycin may be substituted for nafcillin if significant concern exists for infection by methicillin-resistant Staphylococcus aureus or resistant Streptococcus pneumoniae. Appropriate therapy should take into account the primary source of infection as well as possible associated complications such as brain abscess, meningitis, or subdural empyema. People with CST are usually treated with prolonged courses (3–4 weeks) of IV antibiotics. If there is evidence of complications such as intracranial suppuration, 6–8 weeks of total therapy may be warranted.All patients should be monitored for signs of complicated infection, continued sepsis, or septic emboli while antibiotic therapy is being administered. Heparin
Anticoagulation with heparin is controversial. Retrospective studies show conflicting data. This decision should be made with subspecialty consultation. One systematic review concluded that anticoagulation treatment appeared safe and was associated with a potentially important reduction in the risk of death or dependency. Steroids
Steroid therapy is also controversial in many cases of CST. However, corticosteroids are absolutely indicated in cases of pituitary insufficiency. Corticosteroid use may have a critical role in patients with Addisonian crisis secondary to ischemia or necrosis of the pituitary that complicates CST. Surgery
Surgical drainage with sphenoidotomy is indicated if the primary site of infection is thought to be the sphenoidal sinuses. Prognosis
Cavernous sinus thrombosis has a mortality rate of less than 20% in areas with access to antibiotics. Before antibiotics were available, the mortality was 80–100%.
