Local Absence of the IPB & Marginal Lateral Temporal Flatness - Lx- (kay)

The differentiation of atrophy and absence of the IPB :
- Sectional atrophy of the IPB structure at 340' to 15', the diameter of the IPB less than 50 micron.
- Localised absence of the IPB at 55' & 70' to 80', the diameter of the IPB is in 0 micron.
The basic requirements / conditions for Space Risk analysis as below :
- Localised absence of the IPB
- Localised hypertrophy of the IPB
- Introflession & Extroflession
- Pigmented IPB or adjacent to the IPB
- Solitary abnormal morphologies of the IPB
In this case study, the localised absence of the IPB was located in various direction along the IPB structure such as 50', 70'~80' and 215'~223'.
Please observe the importance correlation of :
1) Localised absence of the IPB - 70'~80' relates to Space Risk 9,10 & 11 correspond to the crypt attached on the collarette at 225', 80' & 75'.
2) The marginal Lateral Temporal Flatness at 75' to 82' correspond to the crypt at 75', 80' and Space Risk 9 & 10.
