Radiological examination of the relationship between the pterygomaxillary junction and fracture pattern.

Background: Le Fort 1 (LF1) osteotomies are widely used to correct midface deformities. To move the maxilla freely, the ptery-gomaxillary junction (PMJ) must be separated. When performing this osteotomy, the pterygoid plate must remain intact.

Histopathological investigation of the effect of chitosan on oral mucous wound healing in experimentally established diabetic rats.

Background: In our study, it was aimed to histopathologically investigate the effects of chitosan on wound healing in the oral mucosa by applying the gel form of experimentally induced diabetes mellitus.

Methods: In our study, 42 male Sprague Dawley rats weighing 340±20 g, 14-16 weeks old, were used. Diabetes induction was achieved by administering 55 mg/kg streptozotocin intraperitoneally (i.

Nasal Airway Function After Prophylactic Intranasal Surgery for Excessive Maxillary Superior Repositioning: A Retrospective Cohort Study Using the Nasal Obstruction Symptom Evaluation Scale.

Purpose: The purpose of this study is to evaluate the degree of nasal airway function after simultaneous intranasal corrective surgery and bimaxillary surgery in patients with excessive superior maxillary repositioning.

Materials And Methods: A retrospective cohort study was conducted on consecutive LeFort I superior repositioning patients who also underwent simultaneous intranasal surgery to prevent airway obstruction between 2015 and 2019. The Nasal Obstruction Symptom Evaluation (NOSE) scale was administered to all participants before the operation and after 1 year.

Comparison of standard miniplates and locked miniplates in post-traumatic fracture stabilization.

Background: Bicortical screws (lag and positional) or miniplates with monocortical screws are generally used for the rigid fixa-tion of the sagittal split ramus osteotomy (SSRO) in maxillofacial surgery. However, in this osteosynthesis method, the plate must be perfectly adapted to the bone to prevent misalignment of the bone segment and occlusal changes. In addition, it is necessary to prevent the position of the condyle in the mandibular fossa from changing after fixation.

Retrospective examination of complications observed in orthognathic surgical surgery in 85 patients.

Background: The aim of our study is to examine the possible complications, risk factors, and solutions encountered in orthog-nathic surgery in the light of the cases; we performed in our clinic.

Methods: This study includes a retrospective analysis of the records of 85 patients who underwent orthognathic surgery between 2015 and 2020 in Istanbul Pendik District Hospital Oral and Maxillofacial Surgery Service. The types of complications encountered during the operations were recorded in the study.

Retrospective Analysis of Zygomatic Implants for Maxillary Prosthetic Rehabilitation.

Purpose: The aim of this study was to evaluate 141 zygomatic implants for the reconstruction of severely atrophic maxillae.

Materials And Methods: In this retrospective case series study, zygomatic implants were placed under general anesthesia. Inclusion criteria were as follows: ASA I or ASA II, age older than 18 years, inadequate bone for restoration with conventional implants, alternative augmentation procedures considered either inappropriate or contraindicated, absence of a medical condition related to implant failure, and providing written consent.

Ocular injuries among oral and maxillofacial surgeons: Have high risk or not? An overview of a two-centered experience.

Background: Oral and maxillofacial surgeons are occupationally exposed to ocular injuries via bodily fluid (ie, blood or saliva), which can carry substantial latent risks, both bacterial and viral. The aim of this study was to determine the prevalence of ocular injury and infection among oral and maxillofacial surgeons during outpatient procedures.

Methods: Data were collected from a consecutive series of 500 surgeries conducted by 26 resident surgeons via a questionnaire.

Evaluation of potential salivary acetaldehyde production from ethanol in oral cancer patients and healthy subjects.

Background: Acetaldehyde has been implicated as a major factor in oral carcinogenesis associated with alcohol consumption. In this study, saliva samples from oral cancer patients and healthy individuals were incubated in vitro with ethanol in order to investigate factors which can influence salivary acetaldehyde production.

Materials And Methods: A total of 66 individuals (40 males and 26 females, mean age 52 years) participated in the study.

Genotoxicity of fixation devices analyzed by the frequencies of sister chromatid exchange.

Background: Metal alloys utilized in the management of jaw fractures may exert genotoxic effects. Our purpose was to compare the genotoxicity of intermaxillary fixation devices containing nickel and chromium to that of titanium miniplates utilized in treatment of jaw fractures through the analysis of sister chromatid exchange.

Methods: In this prospective study, in a total of 28 non-smoker patients (10 females, 18 males; mean age 33.

Bimaxillary surgery in Class III malocclusion: soft and hard tissue changes.

The aim of this study was to quantify anteroposterior facial soft tissue changes with respect to underlying skeletal movements after Le Fort I maxillary advancement and mandibular setback surgery with sagittal split osteotomy in Class III skeletal deformity by using lateral cephalograms taken before and after the operation. The material consisted of 31 patient (15 female, 16 male cases, mean age was 26.7 ± 2.

[The use of botulinum toxin type A in masseter muscle hypertrophy: long-term effects and lasting improvement].

Objectives: In this study, we aimed to evaluate the long-term efficacy of botulinum toxin A injection in reducing the masseter muscle thickness.

Patients And Methods: Between 2007 and June 2008, we retrospectively analyzed the data from 28 patients (21 females, 7 males; mean age: 25.5±4.

Facial soft tissue changes after maxillary impaction and mandibular advancement in high angle class II cases.

The aim of this study was to determine the vertical and anteroposterior alterations in the soft, the dental and the skeletal tissues associated with the facial profile after Le Fort I maxillary impaction in conjunction with sagittal split osteotomy for mandibular advancement performed in patients with a high angle Class II skeletal deformity.The study population consists of 21 patients (11 females and 10 males, mean age 24.5±1.

Cervical wear and occlusal wear from a periodontal perspective.

The aim of this study was to investigate whether cervical wear was associated with occlusal wear and clinical periodontal parameters in relatively older adults. A total of 30 patients, with multiple non-carious cervical lesions (NCCLs) and without a disease or condition that could cause heavy tooth wear, were included in the study. The periodontal parameters including plaque index, probing pocket depth, gingival recession (GR) and tooth mobility were obtained from 641 teeth of which 475 (74·1%) displayed NCCLs.

Orbital pain and headache secondary to overfilling of a root canal.

A 35-yr-old woman was referred to the Istanbul University, Faculty of Dentistry, Oral Surgery Department with complaints of orbital pain and headache. Panoramic radiographs showed overfilling of a maxillary premolar, which caused a perforation in the maxillary sinus floor. The etiology, clinical manifestations, and treatment of this complication are discussed with emphasis on early surgical intervention to decrease the risk of a superimposed aspergillosis infection.
