The Bone Mineral Density of the Lateral Skull Base and its Relation to Obesity and Spontaneous Cerebrospinal Fluid Leaks

Abstract: There appears to be no difference between the BMD of the lateral skull base as it relates to obesity or spontaneous CSF leaks compared with normal weight controls. These findings suggest the BMD does not have a significant role in the development of lateral skull base thinning or dehiscence leading to CSF leaks.

“…A history of temporal bone trauma should raise suspicion for post-traumatic CSF leak, as demonstrated by Case 1. Conversely, a history of obesity, OSA and/or IIH should prompt further workup for sCSF-L (2–4,9–14,16–28,37). However, as demonstrated by cases 2 and 3, these demographic features need not be present for a patient to develop a “spontaneous” leak.…”

“…Of the few previous tegmen measurement algorithms that have been reported, only one has focused on tegmen bone mineral density. 13 Our measurement algorithm is different from that one in that we designed ours to focus specifically on areas of potential pathophysiology. In contrast, previous algorithms have taken a broader measurement of the tegmen as a whole.…”

“…We did not find any significant differences in bone mineral density between obese and non-obese patients, in agreement with one previous quantitative study by Hatch et al from 2018, which reported no difference in bone mineral density of the lateral skull base as it relates to obesity or spontaneous CSF otorrhoea compared with normal-weight controls. 13 To date, the Hatch et al study remains the only published study on the quantitative analysis of tegmen bone mineral density.…”
