| Concept | Tos Classification |
| Description | A classification of the degree of tympanic membrane pars flaccida retraction, related to extent and severity and as described by Tos and Poulsen. |
| Use | Use to record the grading of tympanic membrane retraction, particularly by specialist physicians. Designed to be optionally nested within the CLUSTER.exam_tympanic_membrane archetype to provide additional detail on tympanic membrane retraction, if it is useful within a given clinical scenario. This archetype extends the Tos Classification to allow recording of Tos Grade 5 which is described in some documentation but is not described in the original paper and appears not to be in common usage. |
| Purpose | To record the grading of attic retraction of the tympanic membrane, based on the classification by Tos and Poulsen. |

| Tos Classification | Tos Classification: Grading of the degree of tympanic membrane pars tensa retraction / atelectasis based on the Tos & Poulson Classification. 1: Grade 1 [Pars flaccida is dimpled and is more retracted than normal. It is not adherent to the malleus (airspace visible).] 2: Grade 2 [Retraction onto neck of malleus - no airspace visible behind membrane.] 3: Grade 3 [Retraction extends beyond osseous malleus full extent seen.] 4: Grade 4 [Erosion of outer attic wall. Part of the retraction pocket may be hidden.] 5: Grade 5 [Bottom of the retraction pocket can be seen only by using an endoscope.] |
