Despite widespread anecdotal evidence of an increase in tonsil stone formation during pregnancy, including messages on internet pregnancy forums, there is little published research on this topic. Here we present three patients who experienced new or worsening of existing tonsil stones during various points of their pregnancy. Additionally, common presentations of tonsil stones as well as the medical and surgical management options are discussed. Physiological changes during pregnancy could be a contributing factor to an increase in tonsil stones during this period. Since patients may voice complaints of tonsil stones to their obstetricians prior to establishing care with an otolaryngologist, it is important that obstetricians are aware of this disease process and its management.
