Pulsed electromagnetic fields (PEMF) as a valid tool in orthognathic surgery to reduce post-operative pain and swelling: a prospective study.

Purpose: PEMF (pulsed electromagnetic fields) founds application in several medical fields to accelerate bone wounds healing and to reduce inflammation. The aim of our study was to evaluate the effectiveness of PEMF in reducing postoperative swelling and pain in patients undergoing orthognathic surgery.

Methods: A prospective observational monocentric study was conducted on a sample of 30 patients undergone to orthognathic surgery in Maxillofacial Surgery Unit of University of Naples Federico II.

Bad splits in bilateral sagittal split osteotomy: A retrospective comparative analysis of the use of different tools.

This study aims to analyse the relationship between the incidence of bad splits and the surgical tools adopteded to perform bilateral sagittal split ramus osteotomy (BSSRO).BSSROs performed by the same experienced surgeon period were reviewed, retrospectively. The patients were divided into three groups according to the surgical instrument used to perform the osteotomy: a Lindemann burr, reciprocating saw or piezosurgery.

Condylar Reshape in Orthognathic Surgery: Morphovolumetric and Densitometric Analysis Based on 3D Imaging and Digital Workflow.

Background: Condylar remodelling (CR) is a complex of phenomena that generates in response of the temporo-mandibular joint to forces and stress to maintain a morphological, functional and occlusal homeostasis. The most worrying aspect of the condylar reshape is the condylar resorption which implies fast loss of vertical dimension (>6% of pre-surgical value), mandibular retraction and open bite with preserved articular function.

Materials And Methods: Six parameters were analysed to study the condyles of twelve patients that underwent orthognathic surgery.

Efficacy of Hilotherapy face mask in improving the trend of edema after orthognathic surgery: a 3D analysis of the face using a facial scan app for iPhone.

Purpose: Cryotherapy after orthognathic surgery is essential for the control of facial edema. The aim of our study is to evaluate the efficacy of Hilotherapy face mask in reducing facial edema after orthognathic surgery, studying facial surfaces with an innovative, fast, economical 3D facial scan system based on an iPhone app.

Methods: Eighty-four patients with Class III were included: 35 patients treated with Hilotherm after orthognathic surgery (Group 1), 32 patients with ice packs (Group 2), 7 patients who refused cryotherapy (not 1 - not Group 2).

Surgical Management of Large Odontogenic Cysts of the Mandible.

Introduction: Odontogenic cysts are defined as those cysts that arise from odontogenic epithelium and occur in the tooth-bearing regions of the jaws. Cystectomy, marsupialization, or decompression of odontogenic cyst are the most common treatments proposed for this pathology. The aim of this study is to retrospectively evaluate the result of decompression based on the volumetric reduction of the cystic cavity and new bone formation by cone beam computerized tomography (CBCT).

Complications after parotid gland surgery Our experience.

Aim: Complications after parotid surgery include deficit of the facial nerve, wound complications, as sialocele and salivary fistula, and Frey syndrome; the goal of this study was to evaluate the relationship between the type of parotid surgery performed and the incidence of each of these complications.

Material Of Study: A total of 184 patients were evaluated and 158 were included in the study. Four different kinds of intervention were made: extracapsular dissection, partial superficial parotidectomy; superficial parotidectomy and total parotidectomy.

Retained upper third molars during Le Fort I osteotomy with downfracture.

Aim: The aim of our study is to demonstrate that the presence of upper wisdom teeth must be evaluated before and during Le Fort I osteotomy because attention must be focused to the disadvantages or facilitations of surgery depending on molar presence.

Materials Of Study: Our study has analyzed two groups, each one including 20 patients, 10 males and 10 females, with an age between 16-30 years. The first group was treated with le Fort I osteotomy leaving in situ the wisdom upper third molars.

Complications after orthognathic surgery: our experience on 423 cases.

Introduction: Orthognathic surgery is widely used to correct dentofacial discrepancies. However, this procedure presents numerous possible complications. The aim of our study is to review intraoperative and postoperative complications related to orthognathic surgery based upon a 10-year period in the Maxillofacial Surgery Department of Federico II University of Naples.

Neck dissection versus "watchful-waiting" in early squamous cell carcinoma of the tongue our experience on 127 cases.

Background: Early oral squamous cell carcinoma (EOSCC) represents about 90% of the oral cancers especially in older males. The etiology is multifactorial, strongly related to tobacco and alcohol abuse, but also infective agents, Human papillomaviruses (HPV16-18), genetic factors and pre-neoplastic lesions seem to be implicated. There is no consensus in the literature for the treatment of early squamous cell carcinoma of the tongue (stages I-II); both an elective neck dissection policy and a watchful-waiting policy have their proponents in the different centers.

Rare fibrolipoma of the tongue: a case report.

Introduction: Lipoma is a benign tumor infrequent in the oral cavity, particularly in the tongue: indeed, lipomas only represent approximately 0.3% of all tongue neoplasia. Compared to conventional lipoma, fibrolipoma of the tongue is a very rare lesion that accounts for around 25-40% of tongue lipomas, and until now, to the best of our knowledge, only 14 cases have been described in which histological diagnosis of fibrolipoma was specifically confirmed.

Impaired mitochondrial protein synthesis in head and neck squamous cell carcinoma.

Human head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer type worldwide, possibly due to the significant role of alcohol and tobacco use in its development. Underlying most cancers are defects in mitochondrial functions such as energy metabolism and apoptosis. In fact, the mutations in mitochondrial DNA (mtDNA), which encode proteins for oxidative phosphorylation (OXPHOS), have been associated with human head and neck cancers.

The pectoralis major myocutaneous pedicled flap: a refined surgical technique.

The pectoralis major myocutaneous pedicled flap is a commonly used flap for reconstructive head and neck surgery, but associated with high complication rates. The purpose of this study was to evaluate a refined surgical technique that can reduce flap complications and compare the proposed technique with the conventional surgical technique. A retrospective analysis was performed on 35 consecutive patients affected by malignant tumors of the head and neck, who underwent a pectoralis major myocutaneous pedicled flap reconstruction in our institution, between 2004 and 2009.

Extracranial primary and secondary meningiomas.

Meningioma is a well-recognized tumour of the central nervous system. However, extracranial non-dural or ectopic meningiomas are rare and in most of the reported cases, meningiomas are diagnosed only after histopathologic examination. Over the last 5 years, the authors have seen three cases.
