In chronic sinusitis, the problem is not the sinuses themselves but the narrowing or blockage of their openings into the nose. During surgery, these passages are widened and, if necessary, polyps, inflamed, or diseased tissue inside the sinus is cleared. However, the sinus cavities are preserved and left in place. In short, sinus surgery is a conservative procedure that aims not to remove the sinuses, but to <strong>restore their natural function by reestablishing ventilation and drainage<\/strong>.<\/p>\n<p><strong>The sinuses are among the most anatomically variable regions of the human body.<\/strong><\/p>\n<p>This means every patient&#8217;s sinus structure can differ significantly. For this reason, when planning <strong>sinus surgery<\/strong>, the most critical factor is not technology alone, but <strong>thorough mastery of sinus anatomy<\/strong> and accurate
