  • Title: Diagnosis of tuberculosis in the head and neck.
    Author: McAllister KA, MacGregor FB.
    Journal: J Laryngol Otol; 2011 Jun; 125(6):603-7. PubMed ID: 21269551.
    Abstract:
    OBJECTIVES: To establish the features of Mycobacterium tuberculosis infection in the head and neck region, and to determine which investigations have the greatest diagnostic accuracy. STUDY DESIGN: Region-based, retrospective cohort study. METHOD: The study included 148 patients with tuberculosis of the head and neck treated in the Greater Glasgow and Clyde region between 2000 and 2007. RESULTS: The following diagnostic sensitivities were calculated: 53 per cent for fine needle aspiration, 95 per cent for core biopsy and 91 per cent for lymph node excision biopsy. There was a statistically significant difference between the sensitivity results for fine needle aspiration versus core biopsy (p = 0.0003) and fine needle aspiration versus excision biopsy (p < 0.0001). There was no statistically significant difference between the sensitivity results for core biopsy and excision biopsy. CONCLUSION: Core biopsy has equivalent diagnostic accuracy to excision biopsy in the investigation of head and neck tuberculosis. We suggest that core biopsy should be used in preference to lymph node excision, as it can be performed under local anaesthetic outside the operating theatre. A proposed algorithm for diagnostic management is included.
