Measurements of Adult Lingual Tonsil Tissue in Health and Disease

Friedman M, Wilson M, Pulver T, et al. Otolaryngol Head Neck Surg. 2010 Apr;142(4):520-5.

OBJECTIVES: To report computed tomography (CT) measurements of lingual tonsil tissue (LTT) in patients with laryngopharyngeal reflux (LPR), obstructive sleep apnea-hypopnea syndrome (OSAHS), both LPR and OSAHS, or neither disease.

RESULTS: The mean LTT thickness for group 1 (21 patients without reflux or OSAHS) was 0.937 mm (range 0-2.67 mm). The mean for group 2 (29 patients with LPR only) was 3.35 mm (range 0-7.4 mm). The mean for group 3 (16 patients with OSAHS only) was 4.29 mm (range 0-9 mm). The mean for group 4 (32 patients with LPR and OSAHS) was 4.00 mm (range 0-19.2 mm). The mean for group 1 was lower than the other 3 groups (P < 0.001).

CONCLUSION: CT images including the tongue base allow precise measurement of LTT thickness. LTT > 2.7 mm was not identified in patients without OSAHS or LPR. The mean LTT for patients with LPR and/or OSAHS was significantly greater than for patients without either disease.
