Computer-assisted navigation in oral and maxillofacial surgery: A systematic review.

Background: The term "navigation" describes a device that can pinpoint critical anatomical features, the most direct path to the target, and the optimal surgical orientation. This study aimed to conduct a comprehensive literature search on computer-assisted navigation for use in oral and maxillofacial surgery. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, relevant studies were retrieved from five electronic databases: Medline, Web of Science, PubMed, Google Scholar, and Saudi Digital Library (SDL). The central question was, "Does the computer-assisted navigation system improve the outcome of surgical procedures in the oral and maxillofacial region?" The Cochrane Risk of Bias 2 was used to determine the various types of bias. Results: Post-traumatic midfacial reconstruction is one of the many fields that have benefited from the use of computer-assisted navigation because of its reliability. It can also be used to extricate difficult foreign entities from the operative zone. Locating critical anatomical components, communicating the surgical plan to the patient, and verifying surgical success can improve the function and appearance of patients with dentofacial abnormalities. In addition, it decreases the surgical error margin and duration. Conclusion: Computer-assisted navigation is promising in surgical practice. The accuracy of surgery can be significantly enhanced by first planning the process in a virtual environment and then performing it under close supervision in real time. In addition, the time required for preoperative planning and surgery can be reduced by creating and improving software programs.

Awareness of Contraceptives and Their Use Among Saudi Women Attending Primary Care Centers in King Abdulaziz Medical City, Riyadh, Saudi Arabia.

Background The objective of this cross-sectional study is to identify the prevalence of contraceptive use and the knowledge and attitudes of Saudi women towards it. Methods We distributed a survey to Saudi women aged 19-49 attending primary care centers under King Abdulaziz Medical City in Riyadh to identify their views on using contraceptives and what they know about them. We calculated the sample size using the Roasoft sample calculator. Results This study enrolled 432 Saudi women. The number of women who were contraceptive users was 249 (57.6%). Among those who were using contraceptives, the most common reason was the idea of taking care of themselves and avoiding consecutive pregnancies (105, 42.2%). Of the non-users, the most common reason was concerns regarding side effects (41%). The most commonly used contraceptive methods were contraceptive pills (55.6%) and intrauterine devices (IUDs) (17.6%). The most commonly used non-pharmacological contraception methods were withdrawal (17.6%) and rhythm (8.6%). Conclusion In this study, factors associated with contraceptive use among Saudi women were explored. Demographic data, type, attitude, and associations provided insight into factors taken into consideration while developing future contraceptives in addition to improving clinical practice.

Prevalence and Risk Factors of Home Accidents Among Children Under Five Years of Age in Al-Baha, Saudi Arabia.

INTRODUCTION: Internationally, home accidents are the main cause of preventable debilities and death among children and young persons. Many times, children survive accidents with physical or mental damage that curtails their activities in the long term. The most commonly reported accidental injuries include head injuries, open wounds, and poisoning. This study aims to assess the prevalence and factors associated with home accidents among children under five years old in the Al-Baha region, Saudi Arabia. METHODS: A descriptive cross-sectional study was conducted among the community population in the Al-Baha region, Saudi Arabia, targeting all accessible parents who have children under five years old. A convenience sampling technique was used for sample collection during the period of three months (May 2023 to July 2023), where all accessible parents who fulfilled the inclusion criteria and agreed to participate were invited to fill out the received online study questionnaire. Section 1 covered the participants' demographic data. The second section covered the children's data and the third section included questions about home accident types, frequency, severity, and causes.  Results: The findings showed that 205 (58.2%) study parents reported a history of home accidents among their children. As for accident data, about 122 (59.5%) of the injured children were males. The most reported home accidents among children were fall/impact with hard objects (58.2%), burn (30.7%), asphyxia (27.6%), and poisoning (24.4%). Families with more than seven members and those with four or more siblings significantly experienced higher home accidents than others (p<0.001). CONCLUSION: In conclusion, the current study showed that home accidents among children under five years of age were mainly falls and burns; they were mainly found among male children and children in families with highly educated mothers and many kids. A majority of the reported cases of home accidents were less severe and the hospitalization rates with complications were very few.

Facial Reconstruction Using Facial Artery Myomucosal Flap: A Comprehensive Review.

The facial artery myomucosal (FAMM) flap is a type of facial flap that is constructed with the buccal mucosa and submucosa along with a portion of the buccinator muscle, which is connected to nearby blood vessels to maintain its blood supply. It is a versatile and reliable option for head and neck reconstruction, particularly in oral cavity defects. This flap is employed in the reconstruction of the floor of the mouth, alveolar cleft surgery, and tongue defect repair. Previous studies have discussed the use of FAMM flaps for facial reconstructions. However, there are no current and updated comprehensive reviews discussing the use of FAMM flaps in facial reconstruction. In light of this, this study aimed to review all relevant studies that discuss the use of FAMM flaps in facial reconstruction.

Facial Reconstruction Using Sternocleidomastoid (SCM) Flap: A Review of the Literature.

The sternocleidomastoid (SCM) flap has been used for a long time in protective coverage of major vessels, reconstruction of intraoral pharyngeal, closure of pharyngo-cutaneous fistulas, and augmentation of soft tissue defects in the oral and maxillofacial region. However, this flap is not yet commonly used due to doubtful blood supply to the flap. This flap offers favorable esthetic results, combined flap, rich vascularization, and the possibility of shifting the two heads of the muscle. Thus, this flap has been used broadly in the maxillofacial region to reconstruct the defects of the post-parotidectomy, mandible, pharynx, and floor of the mouth defects. Previous studies discussed the use of a SCM flap following parotidectomy. However, few studies explained the use of SCMs in facial reconstruction. This study aims to review published articles discussing the use of SCMs for facial reconstruction.

Outcomes of Cataract Surgery in Diabetic Patients in King Abdulaziz Medical City in 2019.

Background In this study, we aimed to analyze various complications following cataract surgery in diabetic patients and compare the outcomes of diabetic patients with comorbidities versus diabetic patients without comorbidities. Methodology This study was conducted in the adult ophthalmology department at a tertiary teaching care center. A retrospective cross-sectional chart review was conducted from January 1, 2019, to December 31, 2019. The selection was made using a non-probability consecutive sampling technique with a data collection sheet to include all male and female Saudi diabetic patients 40-80 years old who underwent cataract surgery in 2019. The data were divided into diabetic patients with comorbidities and diabetic patients without comorbidities to assess the postoperative complications in both groups. SPSS version 26 (IBM Corp., Armonk, NY, USA) was used for data analysis. Results This study analyzed 290 diabetic patients; the most common age group was more than 65 years old (150, 51.7%), with slightly more females (147, 50.7%). A total of 181 (62.7%) patients had complications after surgery, and 255 (87.9%) patients had comorbidities. The most reported complication was corneal edema (181, 62.4%). Additionally, hypertension was the most frequently reported comorbidity (206, 71%). We also found that complications after cataract surgery were more common among females (p = 0.025). Conclusions The most prevalent postoperative cataract surgery complication was corneal edema in 181 (62.4%) patients. Despite comorbidities, no changes were reported in the prevalence of postoperative complications.

Public Awareness of Colorectal Cancer Screening in the Al-Baha Region, Saudi Arabia, 2022.

BACKGROUND: According to the WHO, cancer is ranked as the second leading cause of death, accounting for an estimated 9.6 million deaths in 2018. This study aimed to assess public awareness about colorectal cancer (CRC) screening and the barriers that prevent Saudi individuals from undergoing CRC screening.  Materials and methods: A cross-sectional study was conducted in the Prince Mishari Bin Saud General Baljurashi Hospital, and a supervised self-administered questionnaire was utilized. Sociodemographic data, knowledge about colorectal cancer, and attitude toward screening were included in the survey. Data were analyzed using IBM SPSS Version 23 (SPSS Inc., Chicago, IL, USA) and Pearson's chi-square test. A P<0.05 was considered statistically significant. RESULTS: A total of 396 eligible participants completed the survey. About 209 (52%) were female, and 124 (31.3%) belonged to the age group of 18-29 years. Nearly (49.7%) knew that detecting colorectal cancer before symptoms appear is possible. About 64% of the participants cited colonoscopy as the screening method for CRC. More than half of the participants (58.1%) expressed their willingness to be screened for colorectal cancer, while only 2.8% reported that they had undergone screening before. Participants with higher educational status demonstrated better knowledge regarding CRC than others (p<0.05). CONCLUSION:  The overall knowledge of CRC was found to be poor in Al-Baha residents, irrespective of age. Implementing new strategies to increase public awareness about colorectal cancer will aid in the early diagnosis of CRC. We recommend targeted education and screening programs to improve the level of screening awareness and aid in the early diagnosis of colorectal cancer.
