Correlations between facial bony structures and soft facial features are fundamental for facial approximation methods The purpose of this study was to assess the strength of the association between craniofacial shape and the shape of the soft-tissue profile and to determine the extent to which it might be possible to predict the latter from the former. Soft-tissue and skeletal facial profile curves were extracted from 86 lateral head cephalograms of a recent Central European population (52 males and 34 females, aged between 19 and 43 years), divided into five parts, segmented automatically and evaluated using geometric morphometrics...

BACKGROUND: For reconstructive surgeons, massive midface defects, including large, full-thickness wounds on the upper lip, can be very challenging. Although there are many methods for reconstruction of upper lip defects, it is difficult to obtain satisfactory restoration of oral functions and good cosmetic results. CASE PRESENTATION: This case report presents a man with massive midface defects, including upper lip, left nose, and cheek defects. Over the previous 2 years, the patient had three reconstructions with sequential free flaps for the resection of recurrent tumors, the first of which was in March of 2016; this resulted in the patient having massive midface defects, including an upper lip defect, a defect on the left side of the nose, and one on the left cheek...

BACKGROUND: Functioning free muscle transplantation (FFMT) is currently the gold standard for the reconstruction of facial paralysis, focusing more on the upper lip reconstruction rather than the lower lip. This study aimed to compare different lower lip reconstructive methods when performing FFMT for facial reanimation. MATERIALS AND METHODS: Retrospective review of FFMT for facial reanimation from 2007 to 2015 was performed. Patients were divided into three groups: Group 1 (n=15), a free plantaris tendon graft anchored to the gracilis muscle was passed into the lower lip to create a loop within; Group 2 (n=12), an aponeurosis tail of the gracilis muscle was attached to the lower lip; Group 3 (n=18), no suspension of lower lip was performed...

BACKGROUND: Proper pre-operative facial analysis that includes a thorough evaluation of both the bony and soft tissue anatomy is paramount to success in performing aesthetic surgery of the face. Ethnic variations in soft tissue profile add an important variable to pre-operative facial analysis. The aim of our study was to determine the role of ethnic variations in soft tissue facial profiles through profile analysis of Iranian male and female patients. METHODS: Photographs of 100 Iranian males and 100 Iranian females (16 to 40 years old) were carried out...

The normal commissure is not a simple joint of the upper and lower lip, but a triangular mucosal area. To reconstruct a symmetrical oral commissure in patients with a unilateral transverse facial cleft, we designed composite vermilion flaps, including triangular flaps. We retrospectively studied 17 patients with unilateral transverse facial clefts from 2013-2016. Three-dimensional images were obtained with a 3-dimensional photogrammetry system at the 1-year follow-up, and we used an anthropometric method to evaluate the postoperative symmetry of the commissure...

The nose is an important landmark of the face and its shape and beauty is of significant concern. The columella is the subunit between the two nostrils that provides support and projection to the nasal tip and has functional role in nostrils, as well as aesthetic. Ethiology for columellar absence or deficiency is diverse, and it is one of the most complex nasal subunits to reconstruct because of its narrow horizontal dimension, its tenuous vascularity and limited availability of adjacent tissue. We present a patient with columellar, membranous septum and upper lip defect, due to oncological resection...

Abel Gonzalez, Dardo Etchichury
INTRODUCTION: Lower lip reconstruction should restore oral competence, speech, and cosmesis. These goals are a challenge when reparing large lower lip defects. Karapandzic flap is a reliable technique with consistent functional and esthetic outcome. In large defects, it might result in disproportion between the upper and lower lips and blunting of the commissures. The Abbe flap is useful as a lip balancing procedure and avoids the rounding of the commissures. PATIENTS AND METHODS: Five cases of lower lip skin cancer treated with Mohs surgery with defects up to 80% were reconstructed with a combination of Karapandzic and Abbe flaps...

BACKGROUND: The human smile is a complex coordinated activity of mimetic muscles predominantly recognizable by a superolateral pull at the commissure and elevation of the upper lip. The aim of this study was to revisit the muscles of facial expression responsible for these motions, evaluate their relational anatomy and orientation, and relate this to optimal positioning of free muscle transfer in smile reanimation. METHODS: Nineteen hemifaces from fresh cadaveric specimens were dissected...

In this review, classical data on the early steps in human odontogenesis are summarized and updated with specific insights into the development of the upper and lower embryonic jaws to help in understanding some oral pathologies. The initial step of human odontogenesis is classically characterized by two parallel horseshoe-shaped epithelial laminae. These originate from the oral epithelium and an ingrowth into the jaw mesenchyme: the internal dental lamina gives rise to deciduous tooth primordia, while the external vestibular lamina represents the developmental base of the oral vestibule...

Repositioning of the maxilla in orthognathic surgery is carried out for functional and aesthetic purposes. Pre-surgical planning tools can predict 3D facial appearance by computing the response of the soft tissue to the changes to the underlying skeleton. The clinical use of commercial prediction software remains controversial, likely due to the deterministic nature of these computational predictions. A novel probabilistic finite element model (FEM) for the prediction of postoperative facial soft tissues is proposed in this paper...

OBJECTIVES: This prospective morphometric study evaluated the growth of the upper dental arch in UCLP patients after early neonatal cheiloplasty and compared the selected dimensions with published data on non-cleft controls and on later operation protocol patients. METHODS: The sample comprised 36 Czech children with nonsyndromic complete UCLP (cUCLP) and 20 Czech children with nonsyndromic incomplete UCLP (UCLP + b). 2-D and 3-D analyses of palatal casts were made at two time points: before neonatal cheiloplasty at the mean age of 3 days (±1 day), and 10 months after surgery at the mean age of 10 months (±1 month)...
