*10.1.1.2.2 Extended lateral rhinotomy*

The lateral rhinotomy incision is further extended inferiorly along the ipsilateral ridge of the philtrum and continued to split the upper lip in paramedian position. After dividing the upper lip, incision is continued laterally along the gingivobuccal sulcus upto the first molar. This approach is required in cases needing exposure beyond the infraorbital neurovascular bundle.
