Balcony genioplasty: a novel technique for better esthetic results in patients with deep mentolabial fold

Abstract

Background To introduce a novel technique for advancement genioplasty helping surgeons to avoid soft tissue difficulties especially in short-faced patients with deep mentolabial fold and everted lower lip. Case presentation In a trapezius-shaped, osteotomy was performed in the chin region. The mobilized segment was advanced, and the existing gap was grafted using interpositional allograft materials. Each side had been fixated by three-hole plates and two screws. The outcomes revealed no change in lower anterior teeth vitality. The patients did not report any changes of sensation in lower lip and chin either. The measurements indicated no increase in depth of mentolabial fold in patients undergoing this surgical technique. The postoperative evaluation showed a successful esthetic outcome for the patient and the surgeon concurrently. Conclusion Based on our experience, the authors concluded that the Balcony technique is a simple and reliable procedure for patients with a deep mentolabial fold.

What is the angular accuracy of regional voxel-based registration for segmental Le Fort I and genioplasty osteotomies?

“…A potential limitation of this study is that it did not account for variability of osteotomy design. For example, variations of the horizontal mandibular osteotomy that extend superiorly 33 to capture the genial tubercle or to mitigate unwanted mentolabial changes 34 would produce larger ROI, and could potentially have greater angular accuracy than was found in the present study. Indeed, the typical genioplasty segment from horizontal mandibular osteotomies consists mostly of cortical bone with a largely homogeneous radiodensity, potentially making R-VBR less accurate, as was found in proximal mandibular segments in sagittal split osteotomies 30 .…”

Bow-tie genioplasty: a novel technique for sagittal reduction of chin using segmental rotation setback movement

“…Since genioplasty was first described in 1942 by Hofer via the extraoral approach, Trauner and Obwegeser introduced genioplasty via an intraoral approach in 1957 [1][2][3]. To achieve more favorable esthetic results, many surgeons have developed and modified various analyses, categories, parameters, and techniques for genioplasty.…”

Computer-assisted horizontal translational osseous genioplasty: a simple method to correct chin deviation

“…A variety of developmental (such as hemifacial hypertrophy), pathological (such as tumors and cysts), traumatic (such as fractures), and functional (such as mandibular displacement) factors can cause chin asymmetry [2,3]. So far, due to the nature and extent of asymmetry, various treatment plans have been introduced to correct these conditions [1,[4][5][6][7]. The use of prefabricated customized implants [7] and genioplasty [8] is considered the most common treatment options for the management of these abnormalities.…”
