Abstract:
Objectives: Investigate the relationship between the mastoid
pneumatization and the paranasal sinus volumes in patients with
unilateral chronic otitis media (COM) and make a contribution to
understanding of COM etiopathogenesis.
Design: 101 patients were divided into two groups: group 1, COM
with isolated tympanic membrane perforation, consists of 51 patients and
group 2, COM with cholesteatoma/retraction pocket, consists of 50
patients. Mastoid and sinus volumes were evaluated on preoperative
temporal bone High-Resolution Computed Tomography (HRCT).
Results: Sphenoid sinus volumes were significantly lower at the
diseased side (p< 0.05), while there is no statistically
difference in the maxillary and frontal sinus volumes. Also, the
sphenoid sinus volumes significantly lower at the side of the ear with
sclerotic mastoid than others (p<0.001).
Conclusions: Long-standing childhood COM might restrict to
pneumatization of the same sided sphenoid sinus considering the delayed
development of the sphenoid sinus compared with other sinuses.
