Importance of the Depressor Septi Nasi Muscle in Rhinoplasty: Anatomic Study and Clinical Application

During the past 5 years, the authors have used a direct trans-lower lid blepharoplasty subperiosteal approach to the lower lid and midface for the purpose of correction of midfacial aging in 757 patients. In a smaller but significant group, this approach has proven valuable in difficult reconstructive situations. The purpose of this article is twofold: (1) to provide a comprehensive retrospective evaluation of the value and promise of the technique and (2) to provide a comprehensive discussion of the pitfalls and complications that have been associated with use of this technique. In addition, technical modifications that may lower the rate of morbidity associated with the use of the procedure are described.
