The Occurrence and Outcomes of Cemento-Osseous Dysplasias (COD) in the Jaw Bones of the Population of Lower Silesia, Poland.

Cemento-osseous dysplasias (CODs) are rare lesions of the jawbone. Their occurrence, localization, type, size, and shape can vary between cases. This fibro-osseous lesion is typically found in the jaw near tooth-bearing areas and is often asymptomatic, discovered incidentally, and may be associated with the periapical region of the teeth.

Late Outcomes of Undiagnosed Unilateral Condylar Hyperplasia and Reoccurrence of Mandibular Asymmetry.

Unilateral condylar hyperplasia (UCH) is a rare cause of asymmetrical mandibular overgrowth because of the presence of an atypical growth in the affected condyle. SPECT (single-photon emission computed tomography) can easily establish the presence of an atypical, prolonged growth exceeding far beyond normal condylar growth and activity. A CT, CBCT, or LDCT (computed tomography, cone-beam computed tomography, or low-dose computed tomography) can confirm the diagnosis by evaluating the scope of bone overgrowth, mandibular basis/ramus asymmetry, tendency to condylar head enlargement, changes in bone density, and occurrence of differences in condylar head shapes, size, and bone structure.

Methods of Definitive Correction of Mandibular Deformity in Hemimandibular Hyperplasia Based on Radiological, Anatomical, and Topographical Measurements-Proposition of Author's Own Protocol.

In order to fully evaluate and establish the degree of bone overgrowth, various radiological studies are essential in the careful planning of the amount of surgical excision. In the presented paper, the authors use self-designed anatomo-topographical reference points for planning the surgeries. Routine panoramic radiographs and low-dose computed tomography based on anatomical landmarks help in measuring the proportions of mandibular bone overgrowth with the following preoperative anatomical landmarks: (Go-Go), (Go(Right)-Gn), (Go(Left)-Gn), and (Me−Gn).

Anatomical and Clinical Implications in Neocondyle Stability After a Condylectomy.

Unlabelled: : A condylectomy of the mandibular condyle is considered to be the treatment of choice in most cases of condylar head hyperactivity. The aim of the procedure is to remove the growth center of the mandible which is responsible for the mandibular enlargement and asymmetry. This surgical procedure has an impact on the condyle shape and position, but the restoration of mandibular movement and a stable joint position (namely, the proper alignment of the newly shaped condylar head within the condyle fossa) should also be considered important surgical outcomes.

Filler Migration and Florid Granulomatous Reaction to Hyaluronic Acid Mimicking a Buccal Tumor.

Hyaluronic acid is among the most commonly used cosmetic fillers. Although considered biocompatible and safe, it may rarely cause a wide range of complications. The authors report a case of migration of hyaluronic acid concomitant with granulomatous inflammatory response that mimicked a buccal tumor.

Ten years of observations and demographics of hemimandibular hyperplasia and elongation.

Introduction: The full epidemiology and etiology of hemimandibular hyperplasia (HH) has not yet been clarified. In most cases it starts before puberty and results in various forms of dento-alveolar and skeletal discrepancies. This study is the first attempt at evaluating and describing some of the authors' key experiences, clinical philosophical approach, and gathered demographic data on hemimandibular hyperplasia and hemimandibular elongation (HE) among the Polish population.

Abdominal Retraction Pad Used in Orthognathic Surgery: A Novel Technique for Nasotracheal Tube Stabilization During Le Fort I Osteotomy.

Many types of surgical osteotomies of the cranio-facial skeleton relay on adequate surgical field preparation. Placement and stabilization of nasotracheal tube during orthognathic surgery is very important. In most cases, long-lasting surgery includes various surgical maneuvers around patient's skull, which depend on accurate nasotracheal tube stabilization.

The Lipomatosis of the Parapharyngeal and Retropharyngeal Space: A Case Report.

Introduction: Lipomas are the most common benign mesenchymal tumors, which account for almost 50% of all soft-tissue tumors.

Case Outline: The case of a 75-year-old patient with a slow growing lesion of para- and retropharyngeal space was reported. The patient was suffering from progressive dysphagia, respiratory obstruction and sleep apnea.

Stem cells and related factors involved in facial nerve function regeneration.

The facial nerve (VII) is one of the most important cranial nerves for head and neck surgeons. Its function is closely related to facial expressions that are individual for every person. After its injury or palsy, its functions can be either impaired or absent.

Primary hyperparathyroidism presenting as a giant cell tumor of the jaws.

Objective: Giant cell tumors of the maxillofacial skeleton are uncommon, they are usually late manifestation of primary hyperparathyroidism. A series of five clinical cases in four women and one man presenting as the giant cell lesions in the maxilla and/or mandible are discussed.

Methods: Biopsy of the lesions, biochemical and hormonal analyses, densitometry and parathyroid scintigraphy were carried out.

Clinical and radiological features of nonfamilial cherubism: A case report.

Background: Cherubism is an uncommon hereditary benign fibro-osseous disorder characterized by bilateral enlargement of the mandible and the maxilla that presents with varying degrees of involvement and a tendency toward spontaneous remission. On radiography cherubic lesions appear as cystic multilocular radiolucencies limited to the jaw bones.

Case Report: A 5-year-old boy was referred to the Department of Maxillo-Facial Surgery due to deformation of the lower and middle section of the face and displacement or absence of teeth.

Bisphosphonate-related osteonecrosis of the jaws: a review of 34 cases and evaluation of risk.

Introduction: The purpose of this study was to identify factors that influence bisphosphonate-related osteonecrosis of the jaws (BRONJ).

Patients And Methods: Patients undergoing treatment for BRONJ (n=34) were evaluated. Sex, age, underlying diagnosis, type of bisphosphonate (BP), duration and route of administration, location of osteonecrosis, clinical symptoms, Actinomyces colonisation, treatment and outcome were recorded.

Impact of tumour characteristic and treatment modality on the local recurrence and the survival in patients with oral squamous cell carcinoma.

Purpose Of The Study: To evaluate the impact of tumour location, local and regional advancement, histological differentiation, status of the surgical margins and radiotherapy on the disease-free time and overall survival rates in patients with oral squamous cell carcinoma.

Material And Methods: A retrospective analysis of 67 patients treated with surgery (61 pts.), radiotherapy (6 pts.

Multiple giant cell lesions in patients with Noonan syndrome and cardio-facio-cutaneous syndrome.

Noonan syndrome (NS) and cardio-facio-cutaneous syndrome (CFCS) are related developmental disorders caused by mutations in genes encoding various components of the RAS-MAPK signaling cascade. NS is associated with mutations in the genes PTPN11, SOS1, RAF1, or KRAS, whereas CFCS can be caused by mutations in BRAF, MEK1, MEK2, or KRAS. The NS phenotype is rarely accompanied by multiple giant cell lesions (MGCL) of the jaw (Noonan-like/MGCL syndrome (NL/MGCLS)).

Treatment of monostotic fibrous dysplasia with pamidronate.

Introduction: Fibrous dysplasia is a condition where fibrous tissue and bone with an altered structure replace normal bone. The craniofacial involvement is difficult to treat due to location, uncontrolled proliferation and compression of nerves. These result in facial asymmetry, pain, cranial nerve deficiencies, loss of vision or hearing, alterations in breathing, etc.

Tissue reaction after implantation of Spongostan, as the carrier of xenogenic bone morphogenetic protein. Experimental study.

Reconstruction or filling of bone defects, especially in the maxillofacial region, often requires use of biomaterials. An implant should fasten healing of the bone gap or it should replace autogenic bone grafts. The combination of bone morphogenetic proteins with suitable carrier may fulfill these requirements.
