Case-control study investigates supratubal recess volume in chronic otitis media, highlighting anatomical differences.

This research examines how supratubal recess volume correlates with chronic otitis media and mastoid pneumatization.
Retrospective analysis of 152 COM patients and 35 control subjects.
Measurement of STR dimensions via 3D HRCT and volume calculation using Horos software.
Mastoid pneumatization type and disease subgroups were analyzed using multivariable regression.
STR volume was significantly larger in pneumatized mastoids compared to diploic and sclerotic types (p < 0.001).
CSOM and CNSOM were positively associated with STR volume (β = 0.220, p = 0.002 and β = 0.416, p < 0.001, respectively).
Diploic and sclerotic mastoids exhibited significantly lower STR volumes compared to pneumatized mastoids (β = −0.519 and β = −0.665; both p < 0.001).

Günay et al. (2026) studied this question.
