A form for use in both the clinical and research setting for documenting the presence and course of otitis media with effusion by pneumatic otoscopy has been developed. The form is based on the data obtained in a large Finnish study on pneumatic otoscopy signs and findings at myringotomy (Karma P, Penttilä M, Sipilä M, & Kataja M, Int J Pediatr Otorhinlaryngol 1989). The rationale for development and the clinical and research applications of the form are discussed.
