Intraoral Approach for Surgical Treatment of Psammomatoid Juvenile Ossifying Fibroma.

Psammomatoid juvenile ossifying fibroma (PJOF) is a rare benign tumor that usually affects the paranasal sinuses, orbit, and skull. In most cases, extensive incisions are necessary for full access to the tumor site. The aim of this paper is to report a case of extensive PJOF in which an intraoral surgical approach was performed with complete excision of the tumor.

Virtual Surgical Planning and One-Stage Treatment of Active Hemimandibular Hyperplasia.

Hemimandibular hyperplasia was first described in 1836 by Adams as a disorder that causes condylar hyperplasia, deforming facial asymmetry and has an unknown etiology. The objective of this study was to report a patient with surgical correction through orthognathic surgery and high condilectomy for the treatment of hemimandibular hyperplasia. The patient complained of pain and cracking in the right temporomandibular joint region and was dissatisfied with the aesthetic appearance of the face.

Methods: This randomized, clinical trial used dependent samples and the split-mouth method. A sample of 30 patients, with impacted or semi-impacted third molars, as well as vertical and mesioangular positions of a similar surgical difficulty (on both sides), was subjected to 2 operations: an experimental operation and a control procedure, with a 30-day wash-out.

Cryosurgery with refrigerant gas as a therapeutic option for the treatment of leukoplakia: a case report.

Leukoplakia is a nondetachable, potentially malignant, white lesion that is commonly found in smokers of advanced age. Leukoplakia occurs more frequently in men; however, there is a higher index of dysplastic changes and malignant transformation in women. The proposed treatments for this disease range from monitoring to surgical excision.

Treatment of Large Thyroglossal Duct Cyst.

The thyroglossal duct cyst is the neck congenital abnormality most common in the childhood. Clinically, it shows itself as a solitary neck mass in the region of hyoid bone, it is painless and can be dislocated during de physical examination and tongue protrusion. The most common treatment is its removal through the Sistrunk technique.

Decision making in third molar surgery: a survey of Brazilian oral and maxillofacial surgeons.

This study was designed to evaluate the variations in decision making among Brazilian oral and maxillofacial surgeons (OMFS) and trainees in relation to third molar surgery. A survey on 18 diverse clinical situations related to the assessment and treatment of the third molar surgeries was conducted during the 20th Brazilian National OMFS meeting. Participants were divided into three groups according to their level of training.

Treatment of condylar fractures with an intraoral approach using an angulated screwdriver: results of a multicentre study.

Background: This multicentre study aimed to investigate long-term radiographic and functional results following the treatment of condylar fractures using an angulated screwdriver system and open rigid internal fixation with an intraoral surgical approach.

The patients were investigated prospectively based on the following variables: age, sex, aetiology, side, location and classification of the fracture, degree of displacement, associated fractures, surgical approach, oral health status, type of osteosynthesis plate, duration of surgery, mouth-opening, complications, and duration of follow-up.

Effect of infrared laser in the prevention and treatment of paresthesia in orthognathic surgery.

Orthognathic surgery is the surgical procedure that makes correcting deformities of the bones in the region of the maxilla and mandible a reality in the Brazilian dentistry. However, this type of surgery usually involves paresthesia in the postoperative period, concerning the surgeons who perform them and generating discomfort to patients. This study aimed at evaluating the effect of infrared laser (830 nm) in the prevention and treatment of paresthesias after orthognathic surgery.

Purpose: The objective of the present study was to conduct a computational, laboratory-based comparison of the biomechanical stability of 2.0 fixation locking plates with different profiles in Class III atrophic mandibular fractures using 3-dimensional finite element analysis.

Materials And Methods: Three-dimensional finite element models simulating Class III atrophic mandibular fractures were constructed.

Survey on complications of orthognathic surgery among oral and maxillofacial surgeons.

Background: Orthognathic surgery is performed to correct dentofacial and craniofacial deformities and improve facial aesthetics, occlusal relations, and the functionality of the stomatognathic apparatus. However, complications in orthognathic surgery may occur at any time during the course of treatment: in the preoperative judgment and planning, during perioperative orthodontic care, or intraoperatively. The aim of the current study was to survey oral and maxillofacial surgeons regarding the main complications of orthognathic surgery.

Nasal airway function after maxillary surgery: a prospective cohort study using the nasal obstruction symptom evaluation scale.

Purpose: To examine nasal airway function using a disease-specific quality-of-life survey instrument in subjects undergoing Le Fort I osteotomy without simultaneous rhinosurgical procedures.

Materials And Methods: We conducted a prospective cohort study of nasal airway function in consecutive Le Fort I osteotomy patients, who had not received simultaneous rhinosurgical procedures, between 2007 and 2008 at Kaiser Permanente Oakland Medical Center. We administered the Nasal Obstruction Symptom Evaluation (NOSE) survey before and 3 months after surgery.

Foreign body ingestion during dental implant procedures.

Two cases of swallowing of foreign material related to dental implants during dental practice are described. A conservative approach by clinical-radiographic follow-up was performed in both cases; however, one of the patients required colonoscopy under general anesthesia for the removal of the impacted foreign body from the intestinal region. These complications not only have associated economic cost but also carry the risk of malpractice litigation against the professional; thus, the surgeon was responsible for all the costs of hospital and surgery management of this case.

Comparative analysis of preemptive analgesic effect of tramadol chlorhydrate and nimesulide following third molar surgery.

The aim of this prospective, randomized, controlled, paired trial was to perform a comparative analysis of the preemptive analgesic effect of nimesulide and tramadol chlorhydrate during third molar surgery. The study was carried out between March and November 2009, involving 94 operations in 47 male and female patients with bilateral impacted lower third molars in comparable positions. The sample was divided into two groups.
