[BACKGROUND] Autologous fat injection techniques are specially performed to restore the lack of face volume. [AIM] However, no reports have focused on the effect of sides of injection on the sagging appearance improvements and facial lifti…

Placing dental implants in microvascular bone free flaps used for reconstructing the mandible or maxilla has been previously reported. However, there is scarce information available on the restorative protocol using short dental implants pl…

[BACKGROUND] Based on a three-dimensional (3D) orthognathic simulation, this technical report introduces a method for augmentation genioplasty using a proximal bone fragment of the mandible, which is typically discarded in intraoral vertica…

[BACKGROUND] The injection of botulinum toxin into the masseter muscle is an important method for improving hypertrophy. However, some patients may experience adverse reactions, such as sagging of the lower jaw. Therefore, we proposed a met…

[BACKGROUND] Despite the significant roles it plays in the functions of the platysma and lower lip, the cervical branch of the facial nerve is often overlooked compared to other branches, but its consideration is critical for ensuring the s…

[BACKGROUND] Ameloblastoma is a locally aggressive, benign tumor presenting in the maxilla and mandible prone to recurrence. Resection greatly limits recurrence; however, reconstruction becomes critical to preserve patients' functionality a…

Facial contouring relates to hard and soft structures that make up the face. Skeletal class II and III subjects present bone structure and position changes, significantly impacting the soft tissues. This study aims to analyze the morphology…

[BACKGROUND] Surgical ciliated cysts occur mainly in the maxillae after radical maxillary sinus surgery; they rarely develop in the mandible. This study aims to gather information on all the characteristics of patients suffering from mandib…

: Defects of the ascending ramus of the mandible, including the condylar head and neck or the whole temporomandibular joint (TMJ), are difficult to reconstruct. Reconstruction is mainly based on the use of alloplastic joint prosthesis, cost…

This systematic review aimed to evaluate the dental prosthetic rehabilitation (DPR) in patients after jaw reconstruction with fibula free flap. Four databases were searched from January 2000 to January 2023. Of the 2507 studies identified, …

Chondrosarcoma is among the most common primary bone tumors in adults. In the mandible, chondrosarcoma is a very uncommon malignant cartilage-producing tumor. This case report shows how virtual planning combined with other digital technolog…

[BACKGROUND] Vascularized fibula free flap (VFFF) remains gold standard for reconstruction of bony defects of the maxilla or mandible. Research and publications in recent years essentially focused on the evolution and improvement of the rec…

Case report. Osteoradionecrosis (ORN) of the jaw is a potentially devastating consequence of head and neck irradiation. The progression of ORN can lead to loss of bone, teeth, soft tissue necrosis, pathologic fracture, and oro-cutaneous fis…

[BACKGROUND] The intricate mechanisms of jowl formation, which ultimately lead to loss of lower jaw definition, skin laxity, and localized fat accumulation, involve interrelated factors such as skin aging, fat redistribution, muscle dynamic…

Parry-Romberg syndrome (PRS) is a rare neurocutaneous and craniofacial disorder characterized by progressive hemifacial wasting and atrophy that predominantly affects children and young adults, with an estimated prevalence of 1 in 700,000 i…

[PURPOSE] The aim of this study is to define the intramuscular nerve distribution of the sternocleidomastoid muscle (SCM) and the innervation zones (IZ) to describe the optimal botulinum toxin injection sites. [METHODS] The cricoid cartila…

This case report presents a mandible reconstruction with temporomandibular joint (TMJ) prothesis for treatment of osteomyelitis infection following a bimaxillary orthognathic and genioplasty surgeries. The patient, a 41-year-old female, pre…

The mandibular interforaminal region has been considered safe for surgical procedures; nevertheless, the risk of injury to neurovascular structures, such as the mental foramen (MF) and its related structures (anterior loop [AL] and lingual …

Genioplasty, a key technique for dentofacial abnormalities, is essential for establishing facial harmony. This surgical procedure entails an osteotomy of the chin, which alters its three-dimensional location to restore overall face equilibr…

[OBJECTIVES] Augmented reality (AR) and virtual reality (VR) are emerging technologies with wide potential applications in health care. We performed a scoping review of the current literature on the application of augmented and VR in the fi…
