Abstract
Abstract: Objective: 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. Methods: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.
