Treatment outcome and prognostic factors of tonsillectomy for palmoplantar pustulosis and pustulotic arthro-osteitis: A retrospective subjective and objective quantitative analysis of 138 patients.

Pustulosis palmaris et plantaris (PPP) and pustulotic arthro-osteitis (PAO) are tonsil-related diseases. Treatment outcome of tonsillectomy and prognostic factors influencing the outcome have not been analyzed quantitatively. We evaluated those using the Palmoplantar Pustulosis Area and Severity Index (PPPASI).
