Maxillary sinus

  • Carlos Yañez


The maxillary sinus may suffer several different pathologies that may be corrected easily with minimally invasive endoscopic procedures. Our efforts must be directed during the surgeries at the uncinate process, and the natural maxillary ostium because they are the most important structures involved in the corrective procedures. Maxillary sinus surgery is underestimated because it is the easiest to imagine, however middle antrumostomy and ostiumplasty should not be done unless there is a pathology within said sinus. The management of the natural ostium should follow the physiological principals that are shown by the mucociliary clearance patterns. One must not touch the ostium whenever possible and maxillary sinus surgery usually consists only in mar-supializing the infundibulum to visualize and decompress the natural maxillary ostium. The two most important aspects of this procedure are to be acquainted with the anatomy and physiology of the natural maxillary ostium, and to have clear criteria in the management of the ostium once the endoscopic paranasal sinus surgery (ESS) commences.
