Radioguided Surgery for the Localisation of Specific Adenopathies in the Head and Neck Area.

Purpose: Intraoperative identification and excision of specific lymphadenopathies is not always easy; it is, therefore, important to have complementary techniques that help us in the identification of these structures intraoperatively. The aim of this study is to present preliminary results of the use of ROLL technique (radioguided occult lesion localisation) as a method of excisional biopsy in the head and neck territory.

Material And Methods: We present 10 cases of patients with difficult to localise lymphadenopathies in the head and neck territory that underwent the ROLL technique.

Unlocking the Temporomandibular Joint: CT, MRI, and Arthroscopic Correlation.

The temporomandibular joint constitutes a synovial connection between the mandible and the skull base and plays a pivotal role in functions such as jaw movement, chewing, and verbal and emotional expression. Temporomandibular joint dysfunction is observed in about 30% of the population, with a higher prevalence in young to middle-aged women. Interestingly, a majority of individuals affected do not report pain, and only 5%-10% of symptomatic cases necessitate therapeutic intervention.

Arthroscopic treatment of temporomandibular dysfunction: preliminary results from a prospective follow up of over five years.

Patients with refractory temporomandibular dysfunction (TMD) despite conservative therapies often require surgical intervention. Although techniques such as arthrocentesis or arthroscopy have been established for years, there remains a dearth of evidence regarding the long-term efficacy of these interventions. This preliminary prospective study aims to elucidate the outcomes of arthroscopic treatment conducted over five years ago in patients with temporomandibular dysfunction.

"Skeletal surgical approach in Down Syndrome with Obstructive Sleep Apnea.".

Failing to address Obstructive Sleep Apnea (OSA) in Down Syndrome (DS) patients can have serious consequences, leading to increased mortality. Moreover, a notable portion of individuals find it challenging to tolerate Continuous Positive Airway Pressure (CPAP). Therefore, this study aims to share our experiences in treating adult DS patients with moderate to severe OSA who don't tolerate CPAP using various surgical approaches.

Temporomandibular Joint: Approach to the Intermediate Space by Triangulation With Transillumination Reference.

Arthroscopy of the temporomandibular joint is a minimally invasive surgical procedure. Nowadays, 3 levels are described depending on the complexity. Level I involves a single puncture with an anterior irrigating needle for outflow.

Influence of Genetic Polymorphisms on the Response to Tramadol, Ibuprofen, and the Combination in Patients With Moderate to Severe Pain After Dental Surgery.

Purpose: We aimed to elucidate the influence on analgesic effect of genetic polymorphisms in enzymes responsible for biotransformation of tramadol and ibuprofen or other possible genes involved in their mechanism of action.

Methods: The study population comprised 118 patients from a multicenter, randomized, double-blind, placebo-controlled, Phase III clinical trial that assessed the analgesic efficacy and tolerability of a single dose of ibuprofen (arginine)/tramadol 400/37.5 mg compared with ibuprofen arginine 400 mg alone, tramadol 50 mg alone, and placebo in patients with moderate to severe pain after dental surgery.

Is There a Relationship Between Age, Personal Factors or Surgical Findings, and Outcome After Temporomandibular Joint Arthroscopy?

Purpose: The variables involved in prognosis after treatment of internal derangement (ID) of the temporomandibular joint (TMJ) are unclear. The purpose of this study was to estimate the frequency and identify which factors are associated with treatment success (or failure) among patients with ID managed with arthroscopy.

Material And Methods: A retrospective cohort study was carried out of patients undergoing TMJ arthroscopy over a 9-year-period.

TMJ arthroscopy with hyaluronic acid: A 12-month randomized clinical trial.

Objectives: To determine the effects of hyaluronic acid (HA) as an adjunct to temporomandibular joint (TMJ) arthroscopy, relative to standard TMJ arthroscopy, in Wilkes stage-III and stage-IV patients.

Methods: A randomized clinical trial design was utilized (ClinicalTrials.gov NCT04110587).

Arthroscopic Management of Synovial Chondromatosis of the Temporomandibular Joint. Case Series and Systematic Review.

Aim: Synovial chondromatosis (SC) is a benign condition that is characterized by the formation of cartilaginous nodules within the synovial tissue of a joint that may detach and form loose bodies inside the articular space. The purpose of this study is to evaluate the use of surgical arthroscopy for the treatment of SC of the temporomandibular joint (TMJ).

Materials And Methods: A series of six patients treated with arthroscopy (one patient requiring an open arthrotomy due to the size of the loose bodies) in our centre between 1997 and 2016 is presented and results are discussed.

Zygomatic distraction osteogenesis for correction of midfacial support after hemimaxillectomy: experience and technical considerations.

Purpose: The maxilla is the functional and esthetic keystone of the midface, and large maxillary defects remain a challenge for reconstructive surgery. Different regional and microvascularized flaps have been used to restore the hemimaxilla. Distraction osteogenesis offers an alternative to complex flaps, with less donor-site morbidity.

Temporomandibular joint disc perforation: long-term results after operative arthroscopy.

Purpose: Disc perforation (DP) is one of the most important pathologic signs of intracapsular temporomandibular joint (TMJ) disease; however, few clinical studies have focused on the arthroscopic management of this feature. The purpose of the present study was to assess whether operative arthroscopy with abrasion of the perforation borders is effective for the treatment of this alteration of the internal derangement of the TMJ.

Patients And Methods: Thirty-six patients (39 joints) who underwent TMJ arthroscopy under general anesthesia and presented with DP (Wilkes stages IV and V) from 1994 through 2006 were included in this study.

The posterior double pass suture in repositioning of the temporomandibular disc during arthroscopic surgery: a report of 16 cases.

Aim: Several procedures have been described to reposition and secure the disc during arthroscopic surgery of the temporomandibular joint. The usefulness of these procedures remains controversial since simple lysis and lavage shows a high percentage of clinical success and it is difficult to obtain radiological imaging of the surgically acquired new disc position. This report describes a new arthroscopic discopexy method, and the clinical as well as radiological results obtained with this new technique.

A 12-year retrospective analytic study of the implant survival rate in 177 consecutive maxillary sinus augmentation procedures.

Purpose: This retrospective study sought to demonstrate the outcome of maxillary sinus elevation surgery in a series of 177 procedures performed over 12 years and to determine the existence of variables that could independently predict implant survival.

Materials And Methods: A retrospective descriptive and analytic study of a series of maxillary sinus elevation procedures performed between 1996 and 2007 was undertaken. The sample was composed of patients with severe atrophy of the posterior maxilla who had been rehabilitated with osseointegrated implants placed in grafted maxillary sinuses.

Prognostic factors influencing contralateral neck lymph node metastases in oral and oropharyngeal carcinoma.

Purpose: The prognostic influence of different clinicopathologic factors in contralateral lymph node metastases of oral and oropharyngeal squamous cell carcinoma (SCC) has been rarely described in the literature. Prediction of these contralateral metastases may be of relevance because this factor is strongly associated with poor prognosis. This study analyzed the relationship between predictor factors and the development of contralateral metastases in oral and oropharyngeal SCC.

Bifocal transport osteogenesis for the reconstruction of adult calvarial defects: a new surgical technique.

Calvarial defects are common problems in craniofacial surgery. They may be explained by surgical interventions, infectious processes, cranial trauma or congenital anomalies. Calvarial defects are particularly challenging because they do not heal spontaneously in humans older than 24 months.

Polymorphisms in the hypoxia inducible factor 1-alpha and the impact on the prognosis of early stages of oral cancer.

Background: Hypoxia-inducible factor-1 (HIF-1) is the key regulator of cellular responses to hypoxia and presumably plays a central role in the control of tumor growth. Polymorphisms or mutations increasing its activity and stability in vitro under normoxia have recently been identified. In this study, we aimed to investigate the effect of C1772T and G1790A single nucleotide polymorphisms (SNPs), located within the exon 12 of HIF-1alpha on the prognosis of early stages of oral squamous cell carcinoma (OSCC).

Le Fort I osteotomy, bilateral sinus lift, and inlay bone-grafting for reconstruction in the severely atrophic maxilla: a new vision of the sandwich technique, using bone scrapers and piezosurgery.

Severe atrophy of the edentulous maxilla and progressive pneumatisation of the maxillary sinus can compromise the insertion of dental implants. In this context, ideal implant positioning is limited by inadequate height, width, and quality of the bone. Le Fort I osteotomy and interpositional bone graft is an excellent treatment concept for the dental rehabilitation of patients with atrophied maxilla and reversed intermaxillary relationship.

Endoscopically-assisted transoral approach for the treatment of subcondylar fractures of the mandible.

Introduction: Treatment of subcondylar fractures of the mandible is one of the most controversial aspects in the field of maxillofacial traumatology. This controversy centers on the positive and negative aspects of open and closed approaches for the treatment of this kind of fractures. Open techniques lead to good reduction and osteosynthesis, but have a high risk of injury to the facial nerve and produce facial scars.

Contralateral lymph neck node metastasis of squamous cell carcinoma of the oral cavity: a retrospective analytic study in 315 patients.

Purpose: In relation to primary squamous cell carcinoma (SCC) of the oral cavity, many clinical and histopathologic factors have been reported to be predictive for lymph neck node relapse. However, few large studies concerning the association between clinical-histopathologic features and the development of contralateral lymph neck node relapse (CLNR) after surgical resection of primary SCC of the oral cavity are available. The purpose of this study was to analyze those factors related to the appearance of contralateral lymph neck node relapse in patients with SCC of the oral cavity primarily treated by means of surgery.

Vascularized free fibular flap for the reconstruction of mandibular defects: clinical experience in 42 cases.

Objective: Since the advent of modern microvascular techniques, the fibula has become a reliable method for the reconstruction of partial or total mandibular defects. The purpose of this study is to evaluate our experience with the use of the vascularized free fibular flap for the reconstruction of mandibular defects following surgical resection.

Patients And Methods: During a 5-year period, 102 consecutive patients were treated in our department for reconstruction of oral and maxillofacial defects, using microvascularized free flaps.

Internal distraction osteogenesis in mandibular reconstruction: clinical experience in 10 cases.

Background: Distraction osteogenesis has been used for reconstruction of bone and soft-tissue defects. The authors present their clinical experience in the reconstruction of mandibular segmental defects by means of internal distraction osteogenesis.

Methods: Ten patients with mandibular defects ranging from 30 to 80 mm in length were treated in the authors' department.

Migration of aluminum silicate from the oral cavity to the submandibular region, with foreign body granuloma formation: report of a case.

We present the first case of foreign body granuloma in the cervical (submandibular) region as a result of migration of noninjected aluminium silicate particles from the oral mucosa. This migration can be explained by macrophage phagocytosis and transport through the local lymphatic network and surgical disruption of fascial layers. The appearance of foreign body granulomas in distant sites may appear several weeks after the local event in a specific disposition according with the migration route.

Elective neck dissection in early-stage oral squamous cell carcinoma--does it influence recurrence and survival?

Background: This study investigates the influence on survival and regional control rates of neck dissection therapy at the time of surgery of the primary tumor in early stages of squamous cell carcinoma (SCC) of the oral cavity.

Methods: A series of 154 patients with pT1N0M0 and pT2N0M0 intraoral carcinomas was analyzed retrospectively. Neck dissection was associated with tumor ablation in 87 patients (56.
