Several reports have suggested a risk of problems due to sinus septum during the
sinus lift procedure. However, there has been no wide-ranging clinico-anatomical study
of sinus septum. This study was performed to examine the occurrence and anatomical
characteristics of sinus septum of the maxillary sinus.
The computed tomographs of the maxillary sinus in 488 patients were analyzed. THe
incidence, location, and orientation of the septum were examined.
The septa were observed in 177 of 488 patients (24.0%). The septa could be observed
at any age (from 7 to 74 years). The incidence of sinus septum was higher in female
(30.8%) than in male (20.8%). The average number of present septa in one patient was
1.56¡¾0.84. One hundred and fifty-seven septa (86.3%) were oriented in a buccopalatal
plane, 16 septa (8.8%) in a sagittal plane, and 9 septa (4.9%) in a transverse plane.
There were no significant differences in location of septa within the maxillary sinus.
These results were suggested that the incidence of sinus septum was 24.0%, and its
shape and location were irregular. The identification of sinus septum should occur prior
to the sinus lift procedure so that the modification of the basic sinus lift procedure can
be planned according to the shape and the location of septa. Then successful results
may be achieved through surgical removal of septa or several modifications to the sinus
lift procedure.
