Hundreds of clinical trials are being planned or conducted at any given time.Basic science research studies the disease process at a distance, such as seeing whether a suspected carcinogen can cause healthy cells to turn into lymphoma cells in the laboratory or how the DNA changes inside lymphoma cells as the disease progresses. The results from basic research studies are generally less immediately useful to people with the disease, but can improve scientists understanding of lymphoma and form the foundation for future, more effective treatments.

Posterior septal perforations, which mainly occur iatrogenically, are often managed with simple observation and are at times intended portions of skull base surgery. Septal perforations that are not bothersome can be managed with simple observation. While no septal perforation will spontaneously close, for the majority of septal perforations that are unlikely to get larger observation is an appropriate form of management. For perforations that bleed or are painful, initial management should include humidification and application of salves to the perforation edges to promote healing. Mucosalization of the perforation edges will help prevent pain and recurrent epistaxis and majority of septal perforations can be managed without surgery. For perforations in which anosmia, or the loss of smell, and a persistent whistling are a concern, the use of a silicone septal button is a treatment option. These can be placed while the patient is awake and usually in the clinic setting. While complications of button insertion are minimal, the presence of the button can be bothersome to most patients. For patients who desire definitive close, surgery is the only option. Prior to determining candidacy for surgical closure, the etiology of the perforation must be determined. Often this requires a biopsy of the perforation to rule out autoimmune causes. If a known cause such as cocaine is the offending agent, it must be ensured that the patient is not still using the irritant. For those that are determined to be medically cleared for surgery, the anatomical location and size of the perforation must be determined.
