Microdebriders are being used with increasing frequency in endoscopic sinus surgery to provide precise removal of soft tissue and bone with simultaneous suction and irrigation. To date, no one has analyzed whether histopathology of tissue processed through a microdebrider is maintained. Fifteen tissue samples (squamous cell cancer, esthesioneuroblastoma, lymphoma, sarcoma, inverted papilloma, benign thyroid, and nasal mucosa) were processed though a microdebrider in various modes and speeds. Pathology slides were developed, coded, and presented as unknowns to the pathologist for diagnosis. Specimens taken from routine biopsy techniques were then compared to those passed through the microdebrider. The study found no significant loss of morphologic features in the tissue passed through the microdebrider. The microdebrider may be used for both routine and oncologic procedures without altering the histopathology necessary for diagnosis.
