Background: The aim of this study was to systematically review the literature on the treatment options of maxillofacial fractures in Iran, complementing a previous article regarding causes and the overall prevalence.

Methods: A systematic search of PubMed, Cochrane Library, Web of Science (WS) and Google Scholar (GS) electronic databases was conducted to identify the relevant articles published up to January 2023. Studies reporting the treatment option of maxillofacial fractures in Iran were included in the analysis. MOOSE guidelines were adopted for the current systematic review. No data or language restriction were applied. Risk of bias across the articles was assessed.

Results: This systematic review included 13 articles with a total of 19,147 treated patients for maxillofacial fractures. ORIF was the most common type of treatment, but complications occurred in approximately 5% of cases. Mandible fractures were not statistically more treated by ORIF than closed reduction or conservative treatment, and no type of treatment was considered statistically preferable depending on the anatomical region affected by Iranian maxillofacial surgeons. The included studies were considered to have a low risk of bias, but many were not clear in reporting cross-referenced data regarding the type of treatment, which could be considered a major flaw.

Conclusion: Overall, this study provides valuable insights into the types of treatment used for maxillofacial fractures by Iranian surgeons and highlights the importance of clear reporting of data in research articles.

Background: We aimed to compare the diagnostic quality of multidetector computed tomography (MDCT) and cone-beam computed tomography (CBCT) in high (HR) and low (LR) resolution modes for assessment of the nasal cavity and paranasal sinuses.

Methods: This in vitro study was conducted on 5 dry human skulls by using a CBCT and a MDCT scanner in HR and LR modes to assess their diagnostic quality for 21 anatomical landmarks of the nose. The quality of images was evaluated by two oral and maxillofacial radiologists and a dentist using a four-point Likert scale of (I) poor, (II) decreased, (III) good, and (IV) excellent. Data were analyzed by STATA at 95% confidence interval. The Chi-square test was applied to compare the quality of visualization of landmarks based on the type of scanner.

Results: The diagnostic quality of HR CBCT and CT for the majority of landmarks was higher than that of LR CBCT and CT (P<0.05). The diagnostic quality of HR CBCT for agger nasi cells (P=0.010), olfactory cleft (P=0.032), sphenoethmoidal recess (P=0.032), and nasolacrimal duct (P=0.014) and LR CBCT for the middle turbinate (P=0.046) and middle meatus (P=0.031) was significantly higher than that of MDCT.

Conclusion: The diagnostic quality of HR CBCT and CT for the majority of the landmarks in the nasal cavity and paranasal sinuses was higher than that of LR CBCT and CT. For the majority of landmarks, the diagnostic quality of CBCT and CT was the same; while for some landmarks, the diagnostic quality of HR and LR CBCT was higher than HR and LR CT. In general, CBCT has high efficacy for evaluation of the paranasal sinuses and the nasal cavity, and provides diagnostic information comparable to those provided by CT, but with a much lower radiation dose.

Polydactyly is a congenital anomaly with a wide range of manifestations that occurs in many forms, ranging from varying degrees of mere splitting to completely duplicated thumb. When duplication occurs alone, it is usually unilateral and sporadic. In this case report, I report left hand polydactyly with 2 more fingers on 5^th finger in a 6 month old male. He subsequently underwent surgical correction, and the over number thumb was removed with associated meticulous skeletal and soft tissue reconstruction. Polydactyly is the most common congenital digital anomaly of the hand and foot. It can occur in isolation or as part of a syndrome. Surgery is necessary to create a single, functioning thumb indicated to improve cosmetics. Skin, nail, bone, ligament, and musculoskeletal elements must be combined to reconstruct an optimal digit. Treatment options of polydactyly depend on the type and the underlying features. In the literature, different surgical treatments for lateral and medial polydactyly are described.

Orthokeratinized Odontogenic Cyst (OOC) is a rare odontogenic cyst, which is important because it has a low recurrence potential, but it has a percentage of the potential for malignant changes. OOC characteristics can be different from OKC (odontogenic keratocyst), which was once classified in its category. The microscopic view of OOC cyst is the reason for its easy identification from OKC, the orthokeratinized epithelial covering and the clear granular layer, and the hyperplasia of the basal layer, and the smooth surface of this cyst. OOC cyst treatment is conservative and can be usually carried out by enucleation. In terms of gender predominance, it is often reported in men. Furthermore, OOC is more common in the 3rd and 4th decades of life. Hereby, we report a rare case of OOC in the posterior mandible of a young adult 18-year-old boy and its treatment method. The clinical and diagnostic points of view and the treatment options were discussed in this article.

Background: We aimed to compare the emergence from anesthesia between the isolated mandibular setback and bimaxillary orthognathic surgeries in Skeletal Class III Patients.

Methods: All healthy patients with skeletal class III deformity admitted to Mashhad Dental School, Mashhad, Iran from the years 2017 to 2018 were included in this study. They were candidates for either bimaxillary orthognathic surgery (Bimax surgery) through a combination of mandibular setback surgery plus maxillary advancement or isolated mandibular setback (Monomax surgery). The predictor variable was the type of jaw displacement and anesthesia duration, while the outcome variable was the duration of emergence from general anesthesia. The duration of emergence from anesthesia was calculated from the time the patient was transported to the recovery room until the time of safely discharging from the recovery room. For statistical analysis, the significance level was set at 0.05 using SPSS 21.

Results: A total of 81 consecutive patients, comprising 45 (55.6%) males and 36 (44.4%) females, with an average age of 23.15±4.58 years were recruited. Among the participating patients, 56 (69.1%) underwent bimaxillary surgery while the other 25 (30.9%) were treated with Monomax surgery. Regardless of the type of performed surgery, the duration of general anesthesia was the only factor to be significantly correlated to the length of emergence from anesthesia (P= 0.001).

Conclusion: Increased exposure time to general anesthesia might result in a longer emergence from anesthesia, despite the type of performed orthognathic surgery. Further clinical trials are needed to support the relevancy.

Background: Patients' attitudes about their nose changes after orthognathic surgeries. We aimed to evaluate the patient's opinion about nasal change and morphologic changes following orthognathic surgery.

Methods: This was a cross-sectional study. The sample was derived from the population of patients who underwent orthognathic surgery in the Oral and Maxillofacial Surgery Department of Shahid Beheshti University of Medical Sciences, Tehran, Iran between 2017 and 2019. Subjects who underwent orthognathic surgery were studied. Subjects filled a modified nose evaluation form before and nine months after orthognathic surgery. For objective assessment, the nasolabial angle, nasofrontal angle, nasofacial angle, tip projection, and tip deviation and alar width were evaluated. Sixty-two patients were studied.

Results: Forty (64.5%) patients did not absolutely like their nose before orthognathic surgeries, two (3.2 %) expressed a little satisfaction, 17(27.4%) answered they liked more or less, and three liked very much. Nine months after orthognathic surgeries, 4 (6.5%) patients did not like their nose, nine patients (14.5%) liked a little, 30 (48.4%) liked more or less, and 19 liked very much. Analysis of the data demonstrated a significant difference in patients' satisfaction with their noses before and nine months after orthognathic surgeries (P<0.001). Patients' satisfaction nine months after orthognathic surgery was not affected by nasal morphologic changes.

Conclusion: It seems, patients' satisfaction with their nose improved after orthognathic surgeries. Patients' attitude was not associated with nasal morphologic changes.

Background: Burns are one of the most important health problems in communities. Traumatic injuries, especially Traumatic Brain Injury (TBI) associated with burns, may increase disability and mortality. In addition to preventing burns, any action for a better treatment approach and early detection of concomitant traumatic injuries can reduce complications, disability, and treatment costs. We aimed to investigate the outcome of children with burn injury with and without TBI.

Methods: In this cross-sectional study, 392 children with burn injuries treated at Motahari Hospital in Tehran, Iran from 2018-2019 were enrolled. Patient demographics, burn injury information and TBI-related information including head trauma and fracture were recorded in a checklist. Patients were divided into two groups of death (24 people) or discharge (368 people) in terms of outcome and the underlying variables were compared in the two groups.

Results: There was no significant difference between the mean age of patients and gender in the two groups. The difference in the length of hospital stay, inhalation injury and skull fracture in the two groups was not statistically significant. The mean burn severity based on Total Body Surface Area (TBSA) and the frequency of TBI in the deceased group was significantly higher (P=0.001).

Conclusion: The severity of burns based on TBSA and TBI is associated with increased mortality among children with burn injuries. The results suggest the need to examine children with burn injuries for TBI using clinical examination or imaging.

Background: Rhinoplasty Outcome Evaluation (ROE) is an easy-to-use questionnaire that allows comprehensive assessment of rhinoplasty-related patient satisfaction. However, the normal values for this questionnaire are not known. Therefore, we aim to validate the ROE questionnaire adapted to Iranian culture.

Method: In this cross-sectional descriptive study, the statistical population consisted of applicants for cosmetic surgery referred to Shahid Rajaee Hospital, Shiraz, Iran, in the autumn and winter of 2017. Two hundred individuals participated in this research by a convenience sampling method. The questionnaire (ROE) was translated to Persian and backward translated to English by independent medical extern Persian speakers with complete English proficiency. The data were analyzed using SPSS software version 23 using exploratory factor analysis.

Results: The findings showed that the Cronbach's Alpha of composite reliability (CR) and average variance extracted (AVE); overall, values above 0.4 were favorable in this measure. In addition, the AVE ranged from 0.50 to 0.59, which confirmed convergent validity. The AVEs of each factor was higher than the squared correlations and confirmed discriminant validity within the constructs. In the presence of significant factor loadings and composite reliability greater than 0.70, convergence validity was confirmed. Furthermore, the higher AVEs for each factor were compared to the squared correlations to confirm discriminant validity.

Conclusion: The Iranian version of ROE is a valid instrument to assess results in rhinoplasty patients.
