Anterior and Posterior Pharyngeal Pillars
The anterior and posterior pillars should appear vascular, smooth and symmetrical (Figure 25). Atypical findings one may encounter include lymphoid aggregates (as found on the posterior pharyngeal wall), areas of pale scarring in a radial or stellate pattern from tonsillectomy, or torn or absent pillars also a result of this surgery. Pathologic findings include:
Asymmetry, unless due to tonsillectomy
Lesions of any kind
Erythema associated with tenderness or exudates
