Advances in clinical anatomy of the superior meatus complex area

In recent years, with the functional endoscopic sinus surgery extensive, at home and abroad on the ostiomeatal complex anatomic variation of the study has been more in-depth, But the clinical diagnosis and treatment found some new problems, that OMC normal or mild lesions, and the upper turbinate, the nasal meatus, butterfly screen recess, olfactory cleft lesions were heavier More and more attention to the problem by clinicians. Some domestic and foreign related literature will this region as the upper nasal sinus ostium compound area. This area includes the upper turbinate, the nasal meatus, butterfly screen recess, olfactory cleft region, after the screen, sphenoid sinus and other major structures. This article will be the region of the lesion type, adjacent anatomical structure of the anatomical variation and pathogenesis were reviewed in order to provide a more detailed clinical anatomical data.
