Porous polyethylene implants have been used as an alternative in the treatment of patients with zygomatic and paranasal projections deficiency. These implants promote a facial rejuvenating effect due to the attenuation of the nasal and chin prominences. The advantages of porous polyethylene include biocompatibility, dimensional stability, easy adaptation and fixation, low complication rate, and its availability in different sizes and shapes. A 27-year-old woman presenting vertical deficiency associated with midface hypoplasia was treated with orthognathic surgery...

INTRODUCTION: The ectopic ciliated cyst is a rare non-odontogenic cyst which occurs as a delayed complication after maxillary sinus radical surgery; this lesion emerges due to the destruction of the sinus mucosa during the surgery and entrapment of the respiratory epithelium in the region. This lesion has been observed in very rare cases following genioplasty and bimaxillary orthognathic surgery. CASE REPORT: We reported a case of the ectopic ciliated cyst in in the mandible of a 37-year-old Iranian woman following genioplasty and Lefort 1 surgery after 2 years...

Multilevel surgery has been established as the mainstay of treatment for the surgical management of obstructive sleep apnea (OSA). Combined with uvulopalatopharyngoplasty, tongue-base surgeries, including the genioglossus advancement (GA), sliding genioplasty, and hyoid myotomy and suspension, have been developed to target hypopharyngeal obstruction. Total airway surgery consisting of maxillomandibular advancement (MMA) with/without GA has shown significant success. Skeletal procedures for OSA with or without a palatal procedure is a proven technique for relieving airway obstruction during sleep...

The complexity of treatment of faciocraniosynostosis justifies the treatment in a reference center for rare diseases. The growth disturbances in the skull and face being variable according to the type of mutation in the FGFr (Crouzon, Pfeiffer, Apert), the strategy is adapted to the phenotype according to the following principles: posterior expansion with or without distraction around 6 months to limit the descent of the cerebellum tonsils and to prevent the turricephalic development; fronto-facial monobloc advancement with internal distraction around the age of 18 months in case of severe exorbitism or breathing impairment...

The chin plays a very important role in overall facial appearance, and aesthetic procedures to augment the chin in patients with microgenia can improve overall facial balance. Many procedures exist to enhance the appearance of a small chin. Procedures include surgeries such as placement of an alloplast implant and bony osteotomy of the mentum (sliding genioplasty). The advantages and disadvantages of each surgical technique are well documented. Although surgical augmentation of the chin has been the gold standard of therapy, recent development of injectable filler products with lifting capacity has changed the way that many practitioners alter chin shape and size...

BACKGROUND: Horizontal advancement genioplasty can be extremely rewarding for microgenia. However, it is challenging for even very experienced surgeon to determine the three-dimensional position of the distant bone fragment during the operation. This study aimed to apply and evaluate computer-aided design (CAD) and computer-aided manufacturing techniques for horizontal advancement genioplasty to improve surgical accuracy. METHODS: Seven patients with microgenia were prospectively enrolled in the study...

Maxillomandibular advancement (MMA) surgery, which is the most effective treatment modality for patients with moderate-to-severe obstructive sleep apnea with apparent skeletal discrepancies, has been modified in conjunction with segmental osteotomies, counterclockwise rotation of maxillomandibular complex, and other adjunctive procedures. However, any single type of MMA could not treat or cure all the patients with obstructive sleep apnea showing different dentofacial and pharyngeal patterns. We aimed to suggest critical decision factors for the selective application of MMA subtypes, categorized as straight MMA with genioplasty, rotational MMA, segmental MMA, and segmental-rotational MMA, in the surgical treatment objective process: anteroposterior position of maxilla, upper lip projection, overjet, lower incisor inclination as sagittal factors, and upper incisor exposure and occlusal plane angle as vertical factors...

BACKGROUND: Previous studies assessing outcomes following orthognathic surgery rely primarily on single-center/surgeon experience. In addition to issues of generalizability, these studies are limited in evaluating the effect of operative volume on patient outcomes. METHODS: Orthognathic procedures were identified in the 1999 to 2011 Healthcare Cost and Utilization Project Nationwide Inpatient Sample. Outcomes included occurrence of any in-hospital complication, extended length of stay (>2 days), and increased costs (>$10,784)...

Maxillomandibular dysmorphia may be associated with structural chin pathologies. Three-dimensional jaws displacements have limits. Specific genioplasty is an additional surgical mean for soft tissues profile normalization. Osteotomy line is examined according an incline angle and a possible lateral extension, as chin wing technique, improves facial shape. Cephalometric set-up with R line analyzes surgical chin movements and impact of lower incisors labial inclination on lower lip and mentolabial fold after advancement genioplasty...

BACKGROUND: Lower face aesthetic contouring is in high demand among Asians with wide and short faces desiring a slim lower face. For this purpose invasive mandible angle reduction and genioplasty are complex procedures with significant risks and downtime. Non-invasive botulinum toxin A injection into bilateral masseters - while popular for lower face contouring - does not address facial length deficiency in wide and short faces. Autologous chin fat grafting is a simple minimally-invasive technique for facial lengthening...
