Facial defects reconstruction by titanium mesh bending using 3D printing technology: A report of two cases.

Ann Med Surg (Lond) 2022 Jun 20;78:103837. Epub 2022 May 20.

Maxillofacial Surgery Department, Aleppo University Hospital, Aleppo, Syria.

Introduction: Facial injuries and deformities have received special attention during the previous decades for their functional, esthetic impairment, surgical challenges related to the location of the intervention, and their relationship to a lower survival rate. Moreover, there have been many surgical reconstructive methods due to the different materials and tools available and thus the final results following the surgical intervention.

Case Presentation: This study was conducted on two patients with severe war injuries; they both suffered from a significant loss in one or more of the following bones: the zygomatic bone, maxilla, nasal bone, infraorbital rim, and mandible. Read More

Midface advancement in an adult patient with Crouzon syndrome: Modified LeFort III + LeFort I osteotomy accompanied by genioplasty and nasal dorsum augmentation.

Dent Res J (Isfahan) 2022 27;19:38. Epub 2022 Apr 27.

Dental Implants Research Center, Dental Research Institute, Isfahan University of Medical Sciences, Isfahan, Iran.

Crouzon syndrome is an autosomal dominant trait, leading to midface deficiency, undeveloped orbits, short nasal dorsum, and exophthalmos as the typical clinical features. Early correction of craniofacial problems can improve patients' quality of life, but many of these patients with Crouzon syndrome are seeking treatment in older ages when they are missed for multidisciplinary management and distraction technique in proper timing. Modified LeFort III osteotomy is one of the treatment options that can be used for proper resolution in adult patients. Read More

Evaluation of Soft Tissue and Airway Changes in Individuals Treated with Mini-Implant Assisted Rapid Palatal Expansion (MARPE).

J Long Term Eff Med Implants 2022 ;32(1):7-18

A.B. Shetty Memorial Institute of Dental Sciences, Mangalore, India.

Introduction: Mini-implant assisted rapid palatal expansion (MARPE) is gradually becoming the treatment of choice to correct the transverse dimension, exceeding the limitations of conventional RME devices. One of the key factors for orthodontic diagnosis and treatment planning apart from a stable occlusion is a balanced and aesthetic facial profile that is influenced by maxillary expansion. Similarly, it also affects the anatomy and physiology of the nasal cavity since nasal airflow is a continuous stimulus for lowering of the palate and for lateral maxillary growth. Read More
