The purposes of this study were to determine the prevalence of concha
bullosa in patients with chronic sinusitis, to assess the origin of th
e pneumatisation (from the anterior or posterior ethmoid cells), and t
o evaluate the significance of the concha bullosa in the genesis of in
flammatory sinus disease. We reviewed the CT studies of 308 patients w
ith chronic sinusitis, assigning four grades of pneumatisation: absent
, small, medium and large. Unilateral or bilateral concha bullosa was
found in 164 patients (53 %). In 79 % of cases it was pneumatised via
the posterior ethmoidal cells and in 21 % via the anterior. A small co
ncha bullosa was associated with abnormalities of the maxillary sinus,
ethmoidal cells and ostiomeatal unit respectively in 49 %, 28 % and 3
4 % of cases, whereas with a large concha bullosa the association was
55 %, 36 % and 41 % respectively on the ipsilateral side and 55 %, 32
% and 41 % on the contralateral side. The usually accepted hypothesis
that the concha bullosa may contribute to the pathogenesis of inflamma
tory sinus disease seems doubtful.
