Long-term follow-up of tonsillectomy efficacy in children with PFAPA syndrome

Introduction: The role of tonsillectomy in the periodic fever, aphthous stomatitis, pharyngitis, and adenitis syndrome, is controversial. Although some studies reported high success rates with tonsillectomy, further investigations are needed with larger numbers of patients. Objective: To seek the long-term outcomes of tonsillectomy in periodic fever, aphthous stomatitis, pharyngitis, and adenitis syndrome. Methods: Case series; multi-center study. The study comprised 23 patients with periodic fever, aphthous stomatitis, pharyngitis, and adenitis syndrome who underwent surgery (tonsillectomy with or without adenoidectomy) between January 2009 and November 2014. Results: 21 (91%) of 23 patients had complete resolution immediately after surgery. One patient had an attack 24 h after surgery, but has had no further attacks. One patient had three attacks with various intervals, and complete remission was observed after 3 months. Conclusions: Tonsillectomy is a good option for the treatment of periodic fever, aphthous stomatitis, pharyngitis, and adenitis syndrome.
