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.

Five-Segment Mandibular Osteotomy: A Novel Approach to the Correction of Complex Post-Traumatic Mandibular Deformities.

BACKGROUND: Post-traumatic mandibular malocclusion is a complex condition that poses a significant challenge to reconstructive surgeons. The malocclusion that ensues from bilateral condylar and parasymphseal fractures presents a particular challenge as it leads to bilateral posterior shortening and lingual tilting of dental arch leading to a combination of open anterior bite, crossbite, overbite, underbite, and/or facial asymmetry. The complexity of such malocclusion requires intricate freedom of movement of the mandibular arch that can be achieved by performing a 5-segment mandibular osteotomy. METHOD: This is a case series of 9 adult patients with significant post-traumatic mandibular malocclusion who were treated with 5-segment mandibular osteotomy technique. This article details the demographics, surgical technique and outcomes in this cohort of patients. RESULTS: All 9 patients in this series had condylar fracture as part of the index mandibular trauma. They have a common post-traumatic deformity of the mandibular arch due to shortening of the vertical mandibular height in the fracture site and variable degrees of lingual tilting leading to crossbite. The 5-segment mandibular osteotomy provided an adequate correction of dental and facial deformities in all 9 patients. One patient had a relapse of the dental malocclusion that required postoperative rescue orthodontics. Furthermore, one patient had a significant postoperative hemorrhage that required a facial artery ligation. CONCLUSION: Post-traumatic mandibular malocclusion is a complex deformity that poses a great challenge to practicing surgeons. Five-segment mandibular osteotomy is a technique that provides ample degrees of movement of mandibular segments that is necessary to correct such deformity.

Morphometric analysis and outcomes following posterior cranial vault distraction in syndromic and multisuture craniosynostosis.

BACKGROUND: Turribrachycephaly is a common feature in many syndromic and multisuture craniosynostoses and is traditionally treated with total cranial vault reshaping and fronto-orbital advancement. A staged approach with posterior cranial vault distraction as a primary procedure followed by anterior cranial vault reshaping has the advantage of reducing the vertical dimension of the skull in a controlled and gradual manner while expanding the cranial volume. The purpose of this study was to evaluate outcomes following posterior cranial vault expansion using distraction osteogenesis at a single tertiary pediatric center. METHODS: This retrospective review included all cases of posterior cranial vault distraction at a single institution from 2008 to 2022 performed by one surgeon. Morphometric outcomes such as Turricephaly Index (TI) and posterior cranial volume (PCV) were assessed from pre- and postoperative computerized tomography scans for patients who underwent posterior cranial vault distraction as a primary first-stage operation. Clinical outcomes and complications were collated. RESULTS: A total of 41 patients (25 females, 16 males; mean age 11 months) with syndromic craniosynostosis (n = 32) and nonsyndromic craniosynostosis (n = 9) were included. The main indication for posterior cranial vault distraction in this cohort was turricephaly (63%). The mean distraction distance was 25.9 mm and the mean decrease in TI was 18%. The estimated increase in PCV from distraction in this cohort was 19.7%. In this cohort of patients, 13 patients (32%) experienced complications but there were no mortalities. CONCLUSION: Posterior cranial vault distraction osteogenesis is an effective surgical procedure to increase intracranial volume and correct turricephaly in children with syndromic and nonsyndromic craniosynostosis. This procedure is considered a safe and effective first-stage cranial operation in children with syndromic craniosynostosis with increased intracranial pressure and or turricephaly.

COVID-19 Restrictions Presented Opportunities and Challenges for Plastic Surgery Residents.

BACKGROUND: Restrictions placed during the COVID-19 pandemic to prevent viral spread led to substantial changes in surgical resident education. The aim of this study was to assess the positive and negative impact of COVID-19 on plastic surgery education and training and provide recommendations for continued competency. METHODS: A cross-sectional online survey of plastic surgery residents across Canada was used to evaluate the impact of COVID-19 on clinical exposure, experience with virtual education, and long-term impact of COVID-19 on surgical training. RESULTS: This study included 61 plastic surgery residents (40% participation rate). Common educational modalities used during COVID-19 included online seminars (95%) and workshops (58%). Teaching sessions were effective if structured around patient cases (72%), recorded (66%), and limited to 1 hour (64%). There were mixed reactions towards online education sessions; residents reported feeling grateful (54%), motivated (38%), enthusiastic (28%), overwhelmed (41%), pressured to participate (23%), and anxious (13%). There were significantly less residents who felt that their clinical exposure was sufficient during (21%) versus before (72%) pandemic restrictions (P < .001). Overall, 87% of residents felt that the pandemic had a negative impact on their training, surgical skill development, fellowship plans, and job prospects. CONCLUSIONS: During the initial wave of COVID-19, residents faced altered educational opportunities, which elicited positive and negative emotions with concern regarding surgical skill development and impact on future career plans. Characterizing early educational impact on residency training to identify opportunities for change is worthwhile as the overall effect of the pandemic is ongoing and remains uncertain.

HISTORIQUE: Les restrictions imposées pendant la pandémie de COVID-19 pour en éviter la propagation virale ont entraîné des changements importants dans la formation des résidents en chirurgie. La présente étude visait à évaluer les répercussions positives et négatives de la COVID-19 sur l'enseignement et la formation en chirurgie plastique et à formuler des recommandations sur le maintien des compétences. MÉTHODOLOGIE: Les chercheurs ont utilisé un sondage transversal en ligne auprès des résidents en chirurgie plastique du Canada pour évaluer les répercussions de la COVID-19 sur l'exposition clinique, l'expérience de l'enseignement virtuel et les conséquences à long terme de la COVID-19 pour la formation en chirurgie. RÉSULTATS: La présente étude incluait 61 résidents en chirurgie plastique (pour un taux de participation de 40%). Les modes d'enseignement couramment utilisés pendant la COVID-19 incluaient les séminaires en ligne (95%) et les ateliers (58%). Les séances d'enseignement étaient efficaces si elles étaient structurées autour de cas de patients (72%), enregistrées (66%) et se limitaient à une heure (64%). Les réactions étaient mitigées quant aux séances de formation en ligne. Les résidents ont déclaré se sentir reconnaissants (54%), motivés (38%), enthousiastes (28%), dépassés (41%), poussés à participer (23%) et anxieux (13%). Beaucoup moins de résidents avaient l'impression que leur exposition clinique avait été suffisante pendant les restrictions liées à la pandémie (21%) qu'auparavant (72%; p<0,001). Dans l'ensemble, 87% des résidents trouvaient que la pandémie avait un effet négatif sur leur formation, l'acquisition de leurs compétences chirurgicales, leurs projets de surspécialité et leurs perspectives professionnelles. CONCLUSIONS: Pendant la première vague de COVID-19, les résidents ont dû composer avec des modifications à leurs possibilités de formation, qui ont donné lieu à des émotions positives et négatives et à des inquiétudes quant à l'acquisition de leurs habiletés chirurgicales et aux répercussions sur leur plan de carrière. Il est intéressant de caractériser les répercussions précoces sur la formation en résidence pour déterminer les occasions de changement, car l'effet global de la pandémie se poursuit et demeure incertain.

Endoscopic Versus Open Total Vault Reconstruction of Sagittal Craniosynostosis.

Sagittal craniosynostosis is the most common form of congenital cranial deformity. Surgical interventions are performed either open or endoscopic. Advancements in minimally invasive surgery have enabled the development of the endoscopic suturectomy technique. This is contrasted to the traditional open cranial vault reconstruction. There is a paucity of data comparing the head shape changes from both techniques. This study aims to compare the morphological outcome of endoscopic suturectomy versus total cranial vault reconstruction. METHODS: This is a retrospective comparative study involving 55 cases of sagittal craniosynostosis, 37 of which has open total cranial vault reconstruction and 18 had endoscopic suturectomy procedure. Preoperative and postoperative 3D photographs of both groups were analyzed and compared. The change in correction between preoperative and postoperative state was measured against a crowd-driven standard for acceptable head shape. RESULTS: Total cranial vault had higher percentage change between pre and postoperative cranial index than endoscopic suturectomy (14.7% versus 7.7%, P = 0.003). However, both techniques were able to achieve the minimum standard of 70% correction (TCV 107.5%, ES 100.4%, P = 0.02). CONCLUSION: Total cranial vault and endoscopic suturectomy are effective in correcting scaphocephaly among children with sagittal craniosynostosis. Additionally, both techniques are able to achieve a percentage correction that exceeds the 70% benchmark established by the lay public.

Best Practice Guidelines for the Management of Acute Craniomaxillofacial Trauma During the COVID-19 Pandemic.

Coronavirus disease 2019 (COVID-19) is an infectious disease that is caused by severe respiratory syndrome coronavirus 2. Although elective surgical procedures are being cancelled in many parts of the world during the COVID-19 pandemic, acute craniomaxillofacial (CMF) trauma will continue to occur and will need to be appropriately managed. Surgical procedures involving the nasal, oral, or pharyngeal mucosa carry a high risk of transmission due to aerosolization of the virus which is known to be in high concentration in these areas. Intraoperative exposure to high viral loads through aerosolization carries a very high risk of transmission, and the severity of the disease contracted in this manner is worse than that transmitted through regular community transmission. This places surgeons operating in the CMF region at particularly high risk during the pandemic. There is currently a paucity of information to delineate the best practice for the management of acute CMF trauma during the COVID-19 pandemic. In particular, a clear protocol describing optimal screening, timing of intervention and choice of personal protective equipment, is needed. The authors have proposed an algorithm for management of CMF trauma during the COVID-19 pandemic to ensure that urgent and emergent CMF injuries are addressed appropriately while optimizing the safety of surgeons and other healthcare providers. The algorithm is based on available evidence at the time of writing. As the COVID-19 pandemic continues to evolve and more evidence and better testing becomes available, the algorithm should be modified accordingly.

Prevalence of Machine Learning in Craniofacial Surgery.

Machine learning (ML) revolves around the concept of using experience to teach computer-based programs to reliably perform specific tasks. Healthcare setting is an ideal environment for adaptation of ML applications given the multiple specific tasks that could be allocated to computer programs to perform. There have been several scoping reviews published in literature looking at the general acceptance and adaptability of surgical specialities to ML applications, but very few focusing on the application towards craniofacial surgery. This study aims to present a detailed scoping review regarding the use of ML applications in craniofacial surgery.

Public Perception of a Normal Head Shape in Children With Sagittal Craniosynostosis.

: A question that remains unanswered is at what level of surgical correction does the public perceive a head shape to be "normal" or "acceptable?" For most cases of non-syndromic asymptomatic craniosynostosis, the parents desire for surgical correction is to improve the cosmetic appearance of head shape. At the time of this writing, the intraoperative surgeons' perspective of what constitutes an acceptable head shape is the target for surgical correction. In introducing an improved objectively cosmetic goal, an appropriate outcome measure would be to assess what the general public considers a normal or acceptable head shape in children with craniosynostosis. METHOD: Twenty-two unique images were presented via an online crowdsourcing survey of a severe case of non-syndromic sagittal craniosynosis gradually corrected to an age and gender matched normalized head shape. Participants were recruited via the Sick Kids Twitter account. Participants were invited to rate the head shapes as "normal" or "abnormal." RESULTS: The 538 participants completed the online survey. Participants were able to reliably and consistently identify normal and abnormal head shapes with a Kappa Score >0.775. Furthermore, participants indicated that a correction of 70% is required in order for the cranial deformity to be regarded as "normal." This threshold closely reflects a normal Cranial Index, which is a widely used morphometric outcome in craniosynostosis. CONCLUSION: Crowdsourcing provides an ideal method for capturing the general population's perspective on what constitutes a normal and acceptable head shape in children with sagittal craniosynostosis. Laypersons are able to reliably and consistently distinguish cranial deformities from a "normal" head shape. The public indicates a threshold correction of 70% in sagittal craniosynosis to regard it as a "normal" head shape.

Practice Management Knowledge Amongst Plastic Surgery Residents in Canada: A National Survey.

Business and practice management principles are critical components of healthcare provision. Business and practice management is currently undertaught in plastic surgery training programs. The objective was to assess the status of business and practice management teaching amongst plastic surgery programs in Canada. An online survey of all enrolled plastic surgery residents was conducted in 2019 to 2020. Participants were invited to rate their knowledge and confidence about core principles in business and practice management. Sixty-five out of 126 residents responded to this survey (response rate, 51.6%). Only 7.8% of participants had previous business and practice management training; 23.1% reported receiving training in business and practice management during their residency. Participants reported a low level of knowledge and confidence in business and practice management (average Likert score between 3 and 4). Participants reported a high desire for future training in business and practice management particularly in billing and coding (91.2%) and business operations (91.2%). Plastic surgery residents in Canada reported a low level of knowledge and confidence about business and practice management. They desire the inclusion of business and practice management training in future curriculum.

Characteristics, Trends, and Factors Associated With Publication Among Residents of Oman Medical Specialty Board Programs.

BACKGROUND: Research during residency is associated with better clinical performance, improved critical thinking, and increased interest in an academic career. OBJECTIVE: We examined the rate, characteristics, and factors associated with research publications by residents in Oman Medical Specialty Board (OMSB) programs. METHODS: We included residents enrolled in 18 OMSB residency programs between 2011 and 2016. Resident characteristics were obtained from the OMSB Training Affairs Department. In April 2018, MEDLINE and Google Scholar databases were searched independently by 2 authors for resident publications in peer-reviewed journals using standardized criteria. RESULTS: Over the study period, 552 residents trained in OMSB programs; 64% (351 of 552) were female, and the mean age at matriculation was 29.4 ± 2.2 years. Most residents (71%, 393 of 552) were in the early stages of specialty training (R ≤ 3) and 49% (268 of 552) completed a designated research block as part of their training. Between 2011 and 2016, 43 residents published 42 research articles (range, 1-5 resident authors per article), for an overall publication rate of 8%. Residents were the first authors in 20 (48%) publications. Male residents (odds ratio [OR] = 2.07; P = .025, 95% CI 1.1-3.91) and residents who completed a research block (OR = 2.57; P = .017, 95% CI 1.19-5.57) were significantly more likely to publish. CONCLUSIONS: Research training during residency can result in tangible research output. Future studies should explore barriers to publication for resident research and identify interventions to promote formal scholarly activity during residency.

Standardization of Cranial Index Measurement in Sagittal Craniosynostosis.

: Cranial index is a widely used 2-dimensional measure of skull form. It has traditionally been calculated as a ratio of the maximal cranial width divided by the maximal skull length. Nevertheless, the points of maximal skull length change dramatically in sagittal craniosynostosis due to variable degrees of frontal and occipital bossing. Therefore, such anatomical changes influence the calculated cranial index. METHOD: This is a retrospective comparative study of 2 methods of measuring cranial index; the traditional method that measures the skull length from glabella to opithcranion versus a modified method that measures the maximal skull length from the most anterior point of the frontal bossing to opithcranion. Cranial indices for 115 patients of radiologically and clinically diagnosed nonsyndromic sagittal craniosynostosis were calculated using both methods. Correlation and Agreements Limits were calculated for comparison between the 2 methods. RESULTS: Males constituted 74.8% (n = 86) of the total sample size with the remaining 29 participants identified as female. The mean age of the study participants was 4.8 months (range 8 days-12 months). The 2 methods were strongly correlated (r = 0.94). The Agreement Limits were calculated to be between 4.02% and 0.18%. CONCLUSION: Typical anatomical changes such as variable degrees of frontal and occipital bossing influence the accuracy of cranial index measurement in sagittal craniosynostosis. Traditional method of cephalic index measurement could underestimate the severity of scaphocephaly.

Proboscis lateralis: A case report of a rare giant craniofacial teratoma in an infant.

Teratomas can occur in almost any region of the body and are the most common extragonadal germ cell childhood tumors. However, craniofacial teratomas are rare. Craniofacial teratomas can present unique features and cause significant functional and aesthetic concerns. There are complex lesions that can have components intra-cranially and extra-cranially. Therefore, their management requires significant multi-stage multidisciplinary surgical procedures. Herein, we present a case of craniofacial teratoma in a child with the phenotype of proboscis lateralis that highlights some of the pertinent point of the diagnosis and management of congenital neonatal teratomas.

The Natural History of Cranial Morphology in Sagittal Craniosynostosis.

BACKGROUND: Children with craniosynostosis have abnormal head shapes. Parents frequently ask whether the abnormal head shape will get worse with time. However, there is no information in the literature to indicate whether the deformity gets worse. OBJECTIVE: To assess the progression of cranial morphology in children with unoperated craniosynostosis. METHODS: A retrospective review of all children with unoperated sagittal craniosynostosis who were referred to the Craniofacial Clinic at the Hospital for Sick Children (SickKids) was conducted. Serial 3D photographs of patients with sagittal craniosynostosis who have not undergone surgical correction were included in the study. There were 14 cases included, with 9 males and 5 females. Ages at time of scans ranged from 3 months to 5 years of age (mean = 28.3 months, SD = 28.2 months). Nine patients had the first scan at age of <12 months. Multiple scans for each patient were sized for volume over time and compared with a normative skull database. RESULTS: The results of measuring skull volume changes over time revealed no significant difference from infants without craniosynostosis. Furthermore, there cranial index was stable over time in patients with craniosynostosis. CONCLUSION: The severity of craniosynostosis does not worsen or improve with time. Parents having difficulty in deciding to proceed with surgical correction of craniosynostosis can be reassured that the skull deformity will remain stable with the growth of their child if they decide not to proceed with surgical correction.

Outcomes of Multi-Trauma Road Traffic Crashes at a Tertiary Hospital in Oman: Does attendance by trauma surgeons versus non-trauma surgeons make a difference?

OBJECTIVES: Trauma surgeons are essential in hospital-based trauma care systems. However, there are limited data regarding the impact of their presence on the outcome of multi-trauma patients. This study aimed to assess the outcomes of multi-trauma road traffic crash (RTC) cases attended by trauma surgeons versus those attended by non-trauma surgeons at a tertiary hospital in Oman. METHODS: This retrospective study was conducted in December 2015. A previously published cohort of 821 multi-trauma RTC patients admitted between January and December 2011 to the Sultan Qaboos University Hospital, Muscat, Oman, were reviewed for demographic, injury and hospitalisation data. In-hospital mortality constituted the main outcome, with admission to the intensive care unit, operative management, intubation and length of stay constituting secondary outcomes. RESULTS: A total of 821 multi-trauma RTC cases were identified; of these, 60 (7.3%) were attended by trauma surgeons. There was no significant difference in mortality between the two groups (P = 0.35). However, patients attended by trauma surgeons were significantly more likely to be intubated, admitted to the ICU and undergo operative interventions (P <0.01 each). The average length of hospital stay in both groups was similar (2.6 versus 2.8 days; P = 0.81). CONCLUSION: No difference in mortality was observed between multi-trauma RTC patients attended by trauma surgeons in comparison to those cared for by non-trauma surgeons at a tertiary centre in Oman.

The Painful Sacrifice: The Epidemiology of Hand Injuries During the Holy Festivals in the Sultanate of Oman-A 10-Year Case-Control Study.

BACKGROUND: The human hand is an important functional and sensory organ. Its complex anatomy reflects its important functional capabilities. Many Muslim countries observe the holy festivals with a traditional sacrifice of an animal in order to share the meat (basic commodity) with beloved ones. During such festivals hand injuries have been reported to increase. This study aimed to compare cases and controls of hand injuries treated at the national trauma center in the Sultanate of Oman during a 10-year time period. METHODS: This is a case-control retrospective review for 10 years in the Sultanate of Oman. The cases were all hand injuries registered and assessed at Khoula Hospital in the Sultanate of Oman during the 3 days of both holy festivals from January 2004 to December 2013. Controls were hand injuries registered and assessed at Khoula Hospital in the Sultanate of Oman during nonfestival days. Data were extracted and collected from the Emergency Department database. A descriptive and comparative analysis was done. RESULTS: There were 1091 cases reviewed in this study. Knife laceration was 2.4 more common during holy festivals than any other time. Extensor tendon injuries were 2.7 more common during holy festivals than nonfestival times. Thumb and index fingers constituted around 40% of the total injuries. Of all patients reviewed, 85% were treated and discharged home without admission. CONCLUSION: Holy festivals in the sultanate of Oman are risky times for hand injuries. Knife lacerations are more common during such times than any other times. Emergency and plastic services should be aware of the pattern of hand injuries during such times in order to prepare and plan services accordingly.

Cutaneous Scar Prevention and Management: Overview of current therapies.

Cutaneous scarring is common after trauma, surgery and infection and occurs when normal skin tissue is replaced by fibroblastic tissue during the healing process. The pathophysiology of scar formation is not yet fully understood, although the degree of tension across the wound edges and the speed of cell growth are believed to play central roles. Prevention of scars is essential and can be achieved by attention to surgical techniques and the use of measures to reduce cell growth. Grading and classifying scars is important to determine available treatment strategies. This article presents an overview of the current therapies available for the prevention and treatment of scars. It is intended to be a practical guide for surgeons and other health professionals involved with and interested in scar management.

Students' contribution to the New Zealand Medical Journal: a 14-year review.

AIMS: Little is known about students' contribution to mainstream New Zealand (NZ) medical literature. This study aimed to analyse the pattern of students' contributions to the New Zealand Medical Journal (NZMJ). METHODS: A retrospective review of all articles authored or co-authored by students, and published in the NZMJ from November 1999 to December 2013. Author and article related information were collected and analysed. RESULTS: There were 288 issues and 4205 articles published between November 1999 and December 2013. Students authored or co-authored 376 (8.9%) articles during this time period. There is an increased trend in the number of articles published during the study period in that students published three times more in 2013 when compared to 2000. Senior medical students and postgraduate students contributed the most with 41.2% and 40.3% of the total student publications respectively. Original articles constituted the most common type of students' publications (67.6%). CONCLUSION: Students contributed substantially to mainstream published NZ medical literature. Students' contribution continues to increase and this reflects the increased participation in research activities. Academic institutions should harness this potential and encourage students to publish their research findings.
