MaxiIlary sinusitis is a common condition. Impaired drainage and reduced ventilation of the
paranasal sinuses are known to increase the risk of a more long-standing inflammaiory
process. MIA had been accepted as a minimally invasive technique for the treatment of
recurrent acute and chronic maxilla), sinusitis, but there is a great difference among
investigators as regard direction and size of widening the natural maxillary ostium. hi our
work MMA was done by different technique and the mucocilialy friction at the maxilla),
side of the ostium was studied to determine the effect of each technique on the .fitnction qf
mucociliary .system, and to know which technique is more physiologic. Fourteen adult
patients ofboth sexes with chronic or recurrent n2axillary sinusitis were included in this study
The evaluation included objective assessment endoscopic nasal examination of the
surgical site and MCC test via the canine .fossa route.
Good healing and normal mucosa was observed in the surgical area in all cases (100 %) in
spite of the different techniques. No evidence of stenosis was noted. Thrre was no crust or
granulation in the MM. Widening the natural maxillary ostium in different techniques
showed active mucociliary flow. However, posterior technique MOP appear to be the more
ideal .The PP. where the lateral wall of MM contains no bone. may be preferred to create a
wide antrostomy opening It is easy to remove 17111COSO precisely without stripping or exposing
bone. |
