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.
