Most simulation models in rhinology are costly and are primarily meant to enhance endoscopic surgical skills. The present study aimed to construct a 3-dimensional model of the nose which is easily constructible with commonly available low cost plaster of Paris (POP) and assess its usefulness in training residents in basic transnasal procedures. A nose model was created using plaster of Paris and assessed for face and content validity by experts in rhinology while a construct validation was performed on five specified tasks by residents. All experts agreed with the resemblance of 10 of the 13 anatomical landmarks in the POP model and its utility in teaching basic transnasal procedures. There was a statistically significant difference in the time taken by I and III year residents in performing a diagnostic nasal endoscopy ( = 0.007), anterior nasal packing with polyvinyl alcohol tampon ( = 0.007), posterior nasal packing with Foley's catheter ( = 0) and nasopharyngeal swabbing ( = 0.025). This study demonstrates the construct of a low cost 3-dimensional POP model and validates its utility in training residents in routine transnasal rhinological procedures. Face and content validation showed a high degree of resemblance to human anatomy with good agreement that this model could increase resident competency. The significant difference in time taken by residents at various levels of experience in performing rhinological procedures also confirmed a reliable construct validity. The described model could be an affordable and easily constructible alternative tool to other simulation models in otorhinolaryngology residency programs especially in developing countries.
