Histopathology of tissue samples removed using the microdebrider technique: Implications for endoscopic sinus surgery

Microdebriders are being used with increasing frequency in endoscopic sinus surgery to provide precise removal of soft tissue and bone with simultaneo us suction and irrigation. To date, no one has analyzed whether histopathol ogy of tissue processed through a microdebrider is maintained. Fifteen tiss ue 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 develop ed, coded, and presented as unknowns to the pathologist for diagnosis. Spec imens taken fr-om routine biopsy techniques were then compared to those pas sed through the microdebrider. The study found no significant loss of morph ologic features in the tissue passed through the microdebrider. The microde brider may be used for both routine and oncologic procedures without alteri ng the histopathology necessary for diagnosis.
