Objectives: To find out size of mastoid bone pneumatization (MBP) according to cleft
lip and palate types of different severity and age subgroups, growing rate of MBP with
aging , ear side dependence according to cleft side.
Method: Measurement and analysis of mastoid bone pneumatization size on x-ray
pictures (made according to Schuler technique) performed plane metrically using
pixels separately for left and right ears. Study group include 14 bilateral (BCLP), 58
unilateral cleft lip and palate (UCLP) and 74 children with isolated cleft palate (ICP) (all
groups have median age of 6.0years) suffered of recurrent episodes of otitis media
with effusion (OME). Control group included 52 non-cleft children suffered of recurrent
episodes of OME (median age of 6.0yr). Comparation of size of MBP of left vs. right
ears for different age groups performed in different cleft lip and palate types.
Results: Size of MBP for total group of tested cleft palate ears was (7.3cm2), that is
significantly smaller thanMBP for total group of OME ears (8.12cm2) (p=0.0018). MBP
in OME ears (8.12cm2) was bigger than in separate cleft type ears: BCLP (6,5cm2,
p=0.0042), UCLP (7.4cm2, p=0.0052) and ICP (7,2cm2 p=0.0022). MBP in SOM ears
showed faster rate of pneumatization growth (development) with aging(r=0.293,
p=0.0035) than total group of cleft palate ears (r=0.174,p=0.003). Mastoid bone
pneumatization in BCLP and UCLP have smallest MBP size which do not grow
significantly with aging. MBP in isolated cleft palate have highest size if compared
with other cleft types. This is only cleft typewith significant growing of MBPwith aging.
Conclusion:Cleft types with highest severy of structural defects bilateral and unilateral
cleft lip and palate have smallest MBP , and no tendency of growth in size with aging.
Ears of children of isolated cleft palate type showed higher size and growing rate
of MBP with aging than. High severity and structural defects in BCLP and UCLP are
accompanied with retardation of development and growth of MBP, what makes them
of high risk for further frequent inflamations and reoccurence of OME, that contributes
to retardation or/and slower development of mastoid pneumatization.
