Cranioplasty in Oman: Retrospective review of cases from the National Craniofacial Center 2012-2022.

Objectives: Cranioplasty is a complex craniofacial and neurosurgical procedure that aims to reinstate the architecture of the cranial vault and elevate both its aesthetic and neurological function. Several reconstructive materials have been thoroughly explored in the search for the optimal solution for cranioplasty. This study aimed to evaluate different material used for cranial reconstruction in Oman. Methods: This retrospective study included all patients who had had cranioplasty procedures performed at Khoula Hospital, Muscat, Oman, from 2012 to 2022. Demographic information, the characteristics of the cranial defect and any complications that occurred post-operatively were analysed. Results: A total of 47 patients were included in this study. The most common cause of cranial defects was craniectomy following traumatic head injury (70.2%) along with excision of fibrous dysplasia (10.6%). The most frequently utilised material for cranial repair was autologous bone grafts (n = 28), followed by polyetheretherketone (PEEK; n = 14). Interestingly, the replacement of bone grafts from previous craniectomy showed a notably high resorption rate (71.4%), in contrast to split calvarial grafts (0%) and other types of bone grafts (14.3%). Additionally, delayed graft infection was observed in 3.6% of the bone graft group and 7.1% of the PEEK group. Conclusion: Patient-specific alloplastic implants such as PEEK have gained popularity for large and complex cranioplasty, as they provide excellent aesthetic outcomes and leave no donor site morbidity. In contrast, bone grafts remain the gold standard for small to medium-sized cranial defects.

A domain specific health-related quality of life of omani patients living with chronic wounds.

AIM: Chronic wounds, defined as wounds that do not heal in a logical set of stages, impact patients' quality of life by disrupting their self-esteem, sleep, social interaction, work capacity, and psychological well-being. Chronic wounds are a prevalent problem in Oman due to the high number of patients with diabetes, sickle cell disease, road traffic accidents, and decubitus ulcer. Therefore, it is paramount to analyse the health-related quality of life (HRQOL) of these patients with chronic wounds. MATERIAL AND METHODS: An observational, cross-sectional, descriptive study with a quantitative approach was conducted among 275 adult patients with chronic wounds in three tertiary hospitals of Muscat from June to December 2021 using a self-reported Cardiff life wound impact questionnaire and the Bates-Jensen wound assessment tool. Data were analysed with IBM SPSS version 23 using inferential statistics and chi-square test. RESULTS: We found that the majority of participants were men (178; 64.7 %), aged between 41 and 60 years (107; 38.9 %), predominantly with diabetic wounds (80; 29.1 %). Respondents reported poor HRQOL across all domains: well-being (63.24 ± 18.092), physical (53.24 ± 18.387), and social (59.54 ± 19.025). Statistically significant poorer HRQOL was observed among the elderly above 60 years, illiterates, those with traumatic wounds, and those receiving medication and dressing as treatment. CONCLUSIONS: Our findings indicate that Omani patients with chronic wounds experience low HRQOL. It is imperative for healthcare providers to offer comprehensive care to these patients. To enhance their quality of life and alleviate suffering, evaluating both the wounds and HRQOL is essential. Such assessments will enable the optimisation of treatment and coping strategies for patients.

Analysis of Blood Cultures from Major Burns Patients in a Tertiary Care Burn Unit in Oman.

Objectives: This study aimed to review the blood stream infections of major burn patients in a tertiary care burn unit to determine the most prevalent infecting organisms in order to have a better empirical therapy protocol. Methods: This retrospective study analysed the blood stream infection of 155 major burn (>20% Total Body Surface Area [TBSA]) patients in Khoula Hospital, Muscat, Oman between January 2014 to December 2019. Results: The median age was 33 years and 57.42% of patients were male. The median TBSA was 38%, mortality was 25.16% and 50.9% of patients had positive blood cultures. The expired patients had higher TBSAs, Abbreviated Burns Severity Index scores and earlier first positive blood cultures. Candida was commonly grown in all the blood cultures, but the most prevalent organisms were Acinetobacter, Staphylococci, Klebsiella, Enterococcus and Pseudomonas. All Acinetobacter species are multidrug resistant. Of the 17 patients who had Kelbsiella grown in the blood culture, 8 grew multidrug-resistant Klebsiella. Only 4 patients' blood cultures grew methicillin-resistant Staphylococcus aureus. The number of blood culture samples taken ranged between 1-28 (median = 6). The first positive blood culture showed that Staphylococcus epidermidis and Acinetobacter were the most common infecting organisms. Conclusions: Multidrug-resistant Acinetobacter was the most predominant microorganism grown from the blood cultures of major burn patients in a tertiary care burn unit. Empirical therapy should include antibiotics that are effective against this organism to reduce the mortality.

Experience of Unilateral Cleft Lip Repair using the Anatomical Subunit Technique in an Omani Population over a Five-Year Period.

Objectives: This study aimed to report the authors' experience with the anatomical subunit technique for unilateral cleft lip repair, which has gained popularity worldwide. Methods: From July 2015 to April 2020, 114 consecutive cases of cleft lip underwent primary cleft lip repair with closed rhinoplasty by a single surgeon. The demographic data, severity and type of the cleft lip, surgical outcomes, including vermillion notching, were assessed by an independent senior surgeon. The rate of revision surgery was collected from the Al-Shifa® - 3Plus healthcare information system (Ministry of Health, Oman). Parents' satisfaction regarding scar quality and lip and nose appearance was collected and all data were statistically analysed. Results: A total of 82 cases satisfied the inclusion criteria. The mean age at surgery for cleft lip was 32 weeks. Among these, 35 cases (43%) were complete cleft lips and 47 cases (57%) were incomplete. Additionally, 43 children (52%) were born of consanguineous marriage. Six patients (7%) needed revision surgery. The digital survey was completed by 40 subjects (response rate: 48.8%) which showed 85% satisfaction rate with the postoperative scar and 77.5% satisfaction with the aesthetic appearance of the nose. Conclusion: The anatomical subunit technique resulted in a predictable outcome indicating a high rate of patient satisfaction with scar quality and nasal and lip symmetry in children with varying severity of cleft lip. The high percentage of consanguinity (52%) in this study highlights the need for more targeted national campaigns involving premarital counselling in the Omani population.
