Maxillofacial prosthetics and digital technologies: Cross-sectional study of healthcare service provision, patient attitudes, and opinions.

PURPOSE: Digital technologies are continuously improving the accuracy and quality of maxillofacial prosthetics, but their impact on patients remains unclear. This cross-sectional study aimed to analyze the impact of facial prosthetics service provision, patients' perception, and digital technology on prostheses construction. MATERIALS AND METHODS: All patients who presented for evaluation and management of facial defects between January 2021 and December 2021 at the ENT clinic were eligible for study enrollment. Patients requiring prosthetic reconstruction of their missing facial parts were included in the study. Forty-five questionnaires were delivered, inquiring about the patients' prosthetic demographics, prosthesis manufacture using 3D technologies, and their perceptions and attitudes. RESULTS: A total of 37 patients responded (29 males, eight females; mean age 20.50 years). The congenital cause was the highest among other causes (p = 0.001) with auricular defects being the highest (p = 0.001). A total of 38 prostheses were constructed and 17 prostheses were retained by 36 craniofacial implants (p = 0.014). The auricular and orbital implants success rates were 97% and 25%, respectively. The implant locations were digitally planned pre-operatively. Digital 3D technologies of defect capture, data designing, and 3D modeling were used and perceived as helpful and comfortable (p = 0.001). Patients perceived their prosthesis as easy to handle, suited them, and they felt confident with it (p = 0.001). They wore it for more than 12 h daily (p = 0.001). They were not worried that it would be noticed, and found it comfortable and stable during various activities (p = 0.001). Implant-retained prosthesis patients were more satisfied with it, and found it easy to handle and stable (p = 0.001). CONCLUSIONS: Congenital defects are the main cause of facial defects in the study country. The overall acceptance of maxillofacial prostheses was good, showing high patient perception and satisfaction. Ocular and implant-retained silicone prostheses are better handled, more stable, and the latter is more satisfying than traditional adhesive prostheses. Digital technologies save time and effort invested in manufacturing facial prostheses.

Use of 3-dimensional imaging and manufacturing for bilateral auricular prostheses: A case series of six patients with congenital auricular defects.

The prosthetic reconstruction of unilateral ear deformity is a straightforward procedure which relies on copying the details, position, and symmetry of the existing contralateral ear. However, reconstructing bilaterally missing ears is challenging. The use of 3-dimensional (3D) technology in the prosthetic reconstruction of the bilaterally missing ears of 6 patients is described. The deformity site was created directly by segmenting the patient's digital scan or indirectly via a desktop scanner. Adequate bone quantity and quality for implant retention and optimal implant locations were also identified virtually. The use of 3D technologies has made it more straightforward to accomplish ear symmetry, as well as to validate the orientation and location of the ears reliably with the minimum subjectivity. The printed ears were matched in shape, surface texture, and anatomy. The skin color was straightforward to record and store so that it could be reproduced at a future time. Overall, the digital manufacture of the ears was controlled, consistent, and reproducible.

Knowledge, Attitude, and Practice of Hearing Loss Among Physicians in Jordan.

PURPOSE: The aim of this study is to assess the knowledge, attitude, and practice of physicians regarding hearing loss and its management among children in Jordan as an example of developing countries. METHOD: The cross-sectional survey composed of 18 questions was used to fulfill the aim of the study. The study population consisted of 335 physicians working in Jordan, with different specialties. The data were collected through site visits to a variety of health care facilities, as well as an online version of the survey to facilitate data collection and ensure participants' comfort. RESULTS: The majority of physicians (30.7%) were general practitioners or family doctors, followed by pediatricians (12.8%). Most of the physicians (88.7%) had experience ranging from 1 to 10 years; the majority of physicians (60.3%) were younger than 30 years of age. Most of the physicians identified the importance of newborn hearing screening. Physicians showed limited knowledge about the management and intervention of infants with permanent hearing loss. Only 11.5% of respondents would refer a child with confirmed hearing loss to an audiologist, and 1.9% of them would refer to a speech therapist. Even though the majority of the physicians (69.0%) reported not receiving any training to deal with deaf and hard of hearing children, they felt confident in talking with parents about hearing loss and its management. CONCLUSIONS: This study revealed that physicians have limited knowledge regarding hearing loss in children as well as its management and intervention. Furthermore, this study illustrates the need for more ongoing medical education programs regarding hearing loss in children.

The Effects of Clinical Factors and Neonatal Morbidities on Hearing Screening among Neonatal Admissions.

BACKGROUND: Hearing loss is an important disorder affecting newborns admitted to NICU. A national hearing screening program using otoacoustic emission testing is an essential tool to identify hearing loss early in neonates, enabling early intervention to avoid further challenges of pediatric deafness. On the other hand, a delay of the auditory pathway maturation in preterm babies compared to term newborns has already been suggested in the literature. Taking this information into account, in this paper, we aim to identify the best time to perform NICU infant hearing screening tests. OBJECTIVES: We aim to study the clinical factors and neonatal morbidities that may affect neonatal hearing screening results using otoacoustic emission test in order to decrease the false-positive test results that increase parental anxiety and increase the need for subsequent investigations. METHODS: This is a prospective cross-sectional study that included 204 infants who were admitted to a tertiary referral hospital NICU unit between September 2017 and May 2018. Both transients evoked otoacoustic emissions (TEOAE), and distortion product otoacoustic emission (DPOAE) screening tests were performed in order to screen hearing loss. RESULTS: Our study included 204 infants, 52.9 % of which were males and 47.1 % females. There were correlations between both hyperbilirubinemia and ventilation ≥ 5 days and the failure rate of the first OAE test results among NICU infants where the P-values were (p=0.0133) and (p=0.0456), respectively. Moreover, 165 babies (80.9 %) passed the first OAE with a mean birth weight of 2759 gram and mean maternal age of 30.6 years, while 39 babies (19.1 %) failed the test with a mean birth weight of 2436 gram and a mean maternal age of 32 years. There was no statistically significant relation between both maternal age and birth weight with failure of the first screening test. CONCLUSION: Our study suggests a higher failure rate of the first OAE in NICU infants who had hyperbilirubinemia or ventilation ≥ 5 days. Therefore, our recommendation is to postpone the first phase of hearing screening for those infants until the first scheduled vaccine appointment to achieve high compliance to attendance and decrease distress to the family that can be associated with false-negative results of the test.

Successful prosthetic salvage of a suboptimal autogenous auricular reconstruction with digital technologies: A report of 3 challenging treatments.

The surgical reconstruction of congenitally missing or malformed ears is challenging and involves complicated surgeries. Ear shape, position, and skin color will likely be compromised in patients with relative anatomic symmetry, and it is easier to reproduce these features with a prosthesis. This article describes the prosthetic reconstruction of 3 patients who had received failed or suboptimal surgical reconstruction of their missing or deformed ears. Challenging characteristics included limited soft-tissue availability, skeletal hypoplasia with prominent concavity defect, and bilaterally missing ears with abnormally low hairline. Three-dimensional planning using a software program was used to determine the ideal implant locations and mirror the contralateral ear. The mirrored ear was 3-dimensionally printed with a stereolithography printer. The skin color was reproduced digitally by using the Spectromatch Pro system.

An Overview of the Effect of Age at Time of Cochlear Implantation on Language Outcomes in Jordan: A Retrospective Cohort Study.

INTRODUCTION: Cochlear Implantation (CI) surgery has long been used as an effective treatment for children with bilateral profound sensorineural hearing loss who failed to benefit from the use of hearing aids. Among other factors, the age at which implantation is done is thought to have an effect on the speech progression outcome of patients postoperatively. OBJECTIVES: The Jordanian CI Program has limited resources, and Jordan has an underdeveloped early screening and intervention program for deafness. In this study, we aimed to explore the effect of age at time of implantation on receptive and expressive language outcomes in Jordan, to guide funding and focus efforts on patient groups who would benefit most, thus reducing unnecessary longterm morbidity and disability, and improving cost efficiency. METHODS: Data was gathered from all major sectors in Jordan on patients who underwent CI from 2006 to 2018 (a total of 1815 patients). We compared the language outcome 2 to 4 years after implantation for patients aged below 3 years, 3 to under 6, 6 to under 9 years, and 9 and older at the time of implantation. RESULTS AND CONCLUSION: We found a statistically significant difference in language outcomes between patients aged below 6 years vs those 6 and older, with better receptive and expressive language outcomes in the younger age groups.

The feasibility of vagal nerve stimulation revision surgery and surgical techniques: a retrospective review.

BACKGROUND: With the large number of VNS implants performed worldwide, the need for removal or replacement of the device in selected cases is emerging, this removal or replacement of VNS can be challenging. AIMS/OBJECTIVE: To describe the feasibility and safety of revising vagal nerve stimulation surgery in terms of the indications, surgical techniques, and outcomes. MATERIALS AND METHODS: A retrospective study, a series of eight cases with VNS implants that needed revision surgery have been reviewed, four devices were completely removed and four were only revised. The revision surgery was performed after a range of 7 months to 6 years, due to different reasons. Initial surgeries and revisions were performed at the otolaryngology department in a major tertiary center. CONCLUSIONS AND SIGNIFICANCE: We concluded that the previously implanted vagal nerve stimulation electrodes can be completely removed without any significant sequelae on the nerve. It may also be re-implanted safely at the previously used segment of the vagus nerve with a similar outcome in seizure control as the initial implantation.

The effects of mode of delivery, maternal age, birth weight, gender and family history on screening hearing results: A cross sectional study.

INTRODUCTION: Congenital hearing impairment is one of the principal issues that make distress to families especially those with a family history of hearing problems. Early detection of hearing impairment can make a difference regarding cognitive, attention, learning, speech, and social and emotional development of babies. Otoacoustic test emission is a very common screening test that can be used to pick up early cases and relieve family stress. We tried to evaluate the factors that may disrupt our results regarding the OAE test. METHODS: A cross-sectional study included infants who were admitted to the nursery unit alone. Infants who were admitted to the NICU unit, infants with craniofacial anomalies, infants with vernix in the external auditory canal, and Infants with Stigmata associated with a syndrome known to include a sensorineural hearing loss were excluded from the study. Both transient evoked otoacoustic emissions (TEOAE) with distortion product otoacoustic emissions (DPOAE) Screening tests were performed by the same professional audiologist experienced in neonatal screening. RESULTS: A total of 1413 newborns (733 males and 680 females) were included in the study. Among them, 1368 babies (96.8%) passed the first OAE in both ears, while 45 babies (3.2%) didn't pass the first OAE in one or both ears.Significant correlations between the female gender and family history of congenital hearing loss with failure of the first OAE test results. Moreover, vaginal delivery (VD) infants had a 1.5-fold higher failure rates of first OAE test screening results in comparison to caesarian delivery (CD) infants. CONCLUSION: Our study demonstrated higher failure rates of the first OAE in female infants, vaginal delivery infants, and infants with a family history of hearing impairment. It is recommended to postpone the first phase of hearing screening for those infants until the first scheduled vaccine appointment to achieve higher compliance attendance, and decrease family stress associated with false-negative results of the test.

Knowledge and Practice of Hearing Screening and Hearing Loss Management among Ear, Nose, and Throat Physicians in Jordan.

Introduction One of the main factors that affect the early diagnosis and intervention of hearing loss is inadequate knowledge by the health care workers. Ear, nose, and throat (ENT) specialists are the main source of information about hearing loss and its management in most developing countries, such as Jordan. Objective The purpose of the present study is to explore the level of knowledge and the practice of hearing screening and hearing loss management for children among ENT physicians in Jordan as an example of health care providers in developing countries of the Middle East. Methods This was a cross-sectional study, adapting a questionnaire of knowledge and the practice of hearing screening and hearing loss management for children. The questionnaire consisted of 2 sections with 20 questions. A total of 40 ENT physicians completed the questionnaire. Results The majority of the respondents acknowledged the importance of hearing screening for children; however, there was limited knowledge regarding hearing loss management and testing. Only 10 of the ENT physicians believed that a referral to an audiologist is warranted, and the majority of the respondents were not aware that a child with a confirmed permanent hearing loss should be referred to a speech pathologist or to a rehabilitation center. Managing unilateral and mild sensorineural hearing loss (SNHL) was another area about which ENT physicians have limited knowledge. Conclusion There is a strong need for professional intervention programs, providing the latest updates and standardizations in the field of audiology and pediatric rehabilitation for ENT physicians.

The impact of COVID-19 outbreak on otolaryngology practice, jordanian experience: A qualitative study.

BACKGROUND: In response to the rapid spread of coronavirus disease 2019 (COVID-19) caused by "severe acute respiratory syndrome coronavirus 2" (SARS-CoV-2), many countries including Jordan have implemented strict lockdowns. These lockdowns were associated with temporary suspension of all outpatient clinics and all elective (Non emergent, non-oncologic) surgical procedures. OBJECTIVE: We aimed to report the impact of COVID-19 outbreak on otolaryngology practice in Jordan. METHODS: Retrospectively we reviewed all admissions to the otolaryngology wards of King Abdullah University Hospital during the lockdown and for the same dates for the year 2019, results were compared.Additionally, an online questionnaire was sent to a sample of Jordanian otolaryngologists in June 2020. The questionnaire was comprised of a series of multiple choice questions regarding each physician's participation in the treatment or screening of COVID-19 patients, the number of consultations during the lockdown, the numbers of elective and emergency surgical procedures performed during the lockdown and the effects the lockdown had on their practices, their patients conditions and teaching and training processes.The study was done in line with the criteria set by the Standards for Reporting Qualitative Research (O'Brien et al., September 2014) [12]. STRENGTHS AND WEAKNESSES: In our study, we aimed to include the experience of all otolaryngology practitioners in Jordan, providing a comprehensive view of the lockdown effects on practice in the region. The data found is likely representative of lockdown effects on all departments, not just otolaryngological practice, and may be beneficial in providing a pathway to minimize any negative impact on patient care.However, our data may be limited due to its dependence on responses through a Whatsapp questionnaire, with no guarantee that the answers provided are fully accurate. It also may have a certain degree of sampling bias, as while the questionnaire was sent to all ENT practitioners in Jordan, answering it was totally optional, and so people who did not respond to the survey were not accounted for. RESULTS: During the lockdown period in Jordan all outpatient clinics were closed, and all elective surgical procedures (non-emergency and non-oncologic procedures) were suspended. During the lockdown it was observed that there was a reduction in the number of admissions related to post-operative complications, head and neck abscesses & infections and foreign bodies related admission when compared to the same period of 2019.A total of 144 otolaryngologists have participated in the questionnaire part of the study. More than half of the participants (n = 80, 55.6%) reported providing 10 or less consultations during the lockdown, more than half of the them have not performed any emergency surgical procedures during the lockdown, and a total of 110 (76.4%) of the 144 participants reported having at least 1 patient whose condition worsened during the lockdown due to lack or delay in medical care. CONCLUSION: The COVID-19 pandemic, and the resultant lockdown period in Jordan has caused a significant shift in otolaryngological practice throughout the country, with a complete cessation of all outpatient clinics and elective surgical procedures and admissions, with activity being limited to oncological and emergency procedures only. These changes have already impacted the dynamics of patient care and might lead to a risk of diagnostic delays which will have severe impacts on patient's health.

Electronic Smoking Behavior Among Adult Males in Jordan.

The use of Electronic cigarettes (E-cigarettes) has considerably expanded especially among adults. This paper highlights the behavior regarding E-cigarettes uses among adult males in Jordan. Moreover, we studied the electronic cigarette devices, the electronic cigarette liquids used in them, and the health-related complaints associated with e-smoking. Among smokers, we studied the association between E-cigarette use and their interest in smoking cessation. A questionnaire-based study regarding electronic cigarette prevalence and awareness among Jordanian individuals was conducted with a total sample size of 1536 participants. The questionnaire was distributed using Facebook and WhatsApp social groups. In this study, we included data of a total of 254 adult male participants after excluding non-E-cigarettes smokers, female smokers, and male smokers younger than 18 years old from the previously published study (Electronic Cigarettes Prevalence and Awareness among Jordanian Individuals) to describe electronic smoking behavior among adult males in Jordan. We described smoking behavior, electronic smoking technologies and materials, source of knowledge, and believe regarding electronic smoking among participants. A total of 254 E-cigarette smokers have participated in this study. 104 participants (40.9%) were found to smoke both traditional and electronic cigarettes, 111 (43.7%) quit traditional cigarette smoking and switched to E-cigarettes, and 39 (15.3%) individuals are exclusively e-smokers. More than half of the participants (n = 144; 56.7%) believe E-smoking is not addictive, and 213 (83.8%) suppose that the overall health effects attributable to E-smoking are less severe and not as serious as those related to traditional smoking. The use of E-cigarettes increased both nationally and globally in the past few years and is considered an emerging modality of smoking among non-smokers. Social media and other internet websites are the main sources of knowledge regarding E-cigarettes. Health-related issues and addiction are thought to be less than traditional smoking in considerable percentages of E-smokers. A more comprehensive conception of E-smoking patterns in Jordan is required to approach this phenomenon. Health authorities in collaboration with governmental policymakers are obligate to adopt strict recommendations to control the promotion of E-smoking through social media and other internet websites to limit its distribution among people especially youths.

Neonatal Screening for Congenital Hearing Loss in the North of Jordan; Findings and Implications.

BACKGROUND: Congenital hearing loss is one of the important illnesses that affect newborns. Early diagnosis and treatment are a challenge for medical authorities in developing countries to improve children's functional, intellectual, emotional, and social abilities. We aimed to study the prevalence of congenital hearing loss in northern Jordan community and identify factors that could affect hearing screening protocol. METHODS: Prospective cross-sectional study of 1595 infants born in our hospital underwent hearing screening tests. Totally, 104 were tested in NICU and the rest examined in the nursery room using Otoacoustic emission (OAE) test as a primary testing tool. The patients were followed in the three hearing screening phases. Factors affecting screening results were studied and analyzed. RESULTS: The total number of newborns who didn't pass the first OAE test in one or both ears were 90 (5.6%); 69 from the nursery group and 21 from the NICU group. In the 2nd screening phase 21 (23.3%) didn't attend the appointment. Sixty-four passed the second screening OAE test. Five newborns (5.6%) had a second refer result in one or both ears and referred for a diagnostic ABR test. Three infants passed the test and two found to have bilateral hearing loss. CONCLUSIONS: Hearing screening test is conducted via a 3-phases-protocol. OAE is used in the first two phases and ABR in the third phase. Hearing results is significantly affected for infants admitted to NICU. The following factors increase OAE fail response: mechanical ventilation for more than 5 days, Hyperbilirubinemia, associated congenital anomalies. Mode of delivery doesn't have statistical significance on hearing screening results.

Prevalence of Frontal Sinus Aplasia in Jordanian Individuals.

Our paper aims to investigate the prevalence of frontal sinus aplasia among Jordanian individuals and compare it with values from different populations. Retrospectively, the study was done for 167 of the paranasal sinuses coronal tomography (CT) for patients who attended the clinic from January 2019 to August 2019 in King Abdullah University Hospital Irbid, Jordan. The authors analyzed the multiplanar CT scans to perform our work. The authors excluded the following images from our study: patients younger than 18 years old, patients with history of skull base trauma that impaired visualization of the frontal sinus, and images with fibro-osseous lesions that impaired the visualization of the frontal sinus. The prevalence of bilateral frontal sinus aplasia is 4.2% among Jordanian individuals and 6.6% is the prevalence of unilateral frontal sinus aplasia. Both values are consistent with average values among different populations. Moreover, we noticed the higher prevalence in both the bilateral and unilateral frontal sinus aplasia in males compared to females. The prevalence of frontal sinus aplasia among Jordanian individuals is almost within the same values among different populations. These numbers regarding the bilateral and unilateral frontal sinus aplasia is crucial to push the surgeon to evaluate CT of the paranasal sinuses preoperatively and focus on the presence of frontal sinuses on CT images to prevent unwanted complications during sinus surgeries.

Overview of Upper Airway Management During COVID-19 Outbreak: Head and Neck Surgeon's Perspective.

At the end of December, 2019, a new virus was named severe acute respiratory syndrome coronavirus 2 appeared in Wuhan, China, and the disease caused is called as coronavirus disease 2019 (COVID-19) by World Health Organization, which to date having infected more than 3,588,773 people worldwide, as well as causing 247,503 deaths. A human to human transmission is thought to be predominantly by droplet spread, and direct contact with the patient or contaminated surfaces. This study aims to provide a comprehensive overview as well as to highlight essential evidence-based guidelines for how head and neck surgeon and healthcare providers need to take into consideration during their management of the upper airway during the COVID-19 pandemic safely and effectively to avoid the spread of the virus to the health provider.

Parents' satisfaction with a trial of a newborn hearing screening programme in Jordan.

OBJECTIVE: This study examines parents' satisfaction level toward a trial of a newborn hearing screening programme (NHSP) that was applied in King Abdullah II University Hospital (KAUH) in Jordan over one year. This is the first study that investigated parents' satisfaction toward a hearing screening programme in the Arab countries, and the results will improve any future screening programmes in the Arabian region. METHOD: The main tool for this study was a questionnaire that was translated and modified from the original version of the Parental Satisfaction with the Newborn Hearing Screening Programme (PSQ-NHSPs1). The questionnaire consisted of 19 items covering five main aspects of the NHSP. The parents' responses were not anonymously given where the parents whose children had undergone the hearing screening were contacted by phone using the data record of the hospital. RESULTS: The majority of the parents were very satisfied with the programme overall and showed great support and appreciation for the effort in testing their babies and increasing their awareness. The satisfaction levels varied among the specific aspects of the programme. Good portion of the parents did not receive the brochure containing information about the screening, and almost half of them did not know the results of the hearing screening. CONCLUSION: Parents were overall satisfied with neonatal hearing screening programme that was conducted at KAUH. However, parents were less satisfied with information related to the test procedure and results. Parents' responses in this study could be used to improve any future hearing screening program in Jordan or in the Arab countries.

Accuracy of intraoperative electrophysiological testing in confirming correct cochlear implant electrode positions.

Objective: To investigate the accuracy of intraoperative electrophysiological studies in detecting incorrectly positioned electrodes in cochlear implant surgery. Study design: A retrospective chart review. Setting: Tertiary referral centre. Patients: In total, 104 consecutive patients with a mean age of 5 years underwent cochlear implant surgery at our centre between January 2012 and December 2013. All patients were implanted with Cochlear Nucleus Freedom implants. Method: A retrospective study to compare intraoperative neural response telemetry (NRT), impedance and electrode position using Stenver's transorbital plain X-ray view. Results: Intraoperative electrophysiological tests for patients with Cochlear Nucleus Freedom implants showed 97% sensitivity and 100% specificity compared with postoperative X-ray imaging. Conclusion: NRT results for the position of cochlear implants were very accurate when checked by X-ray imaging showing that this technique is sufficient in most cases. Stenver's plain X-ray view is needed in complicated cases with abnormal NRT testing or difficult electrode insertion.

Prevalence and correlations of temporomandibular disorders in Northern Jordan using diagnostic criteria axis I.

AIM: The aim of the present study was to document the prevalence and possible correlations of temporomandibular disorders (TMD) in a sample of participants from Northern Jordan. METHODS: A total of 368 adult participants were consecutively selected from visitors to a major health facility in Northern Jordan and examined according to the diagnostic criteria (DC) for TMD (DC/TMD) protocol. Patients with conditions that could interfere with TMD diagnosis were excluded. Pearson correlation and analysis of variance statistical tests were applied. Statistical significance was set at P ≤ 0.05, with a 95% confidence interval. RESULTS: A total of 98 patients (26.7%) had 1 TMD diagnoses; 60 participants (16.3%) had a pain-related TMD diagnosis, 48 (13%) had intra-articular joint disorders (IAD), and 16 had both pain-related TMD and IAD. In addition, six (1.6%) participants were found to have degenerative joint disease. Females were found to have a higher prevalence of pain-related TMD diagnoses (r = 0.111, P = 0.034) and headache (r = 0.129, P = 0.013) than males. Clicking was positively related to both pain-related TMD (r = 0.154, P = 0.003) and IAD (r = 0.576, P = 0.000). CONCLUSION: The frequency of TMD and related features was reported in a Northern Jordanian population using DC/TMD for the first time, and the results are comparable to other populations in similar study settings.

Direct 3D Printing of Flexible Nasal Prosthesis: Optimized Digital Workflow from Scan to Fit.

A maxillofacial prosthesis is a successful treatment modality to restore missing facial parts. Digital technologies and 3D printing are employed in constructing facial prostheses such as ears; however, their application is still partial, and final prostheses are usually manufactured conventionally using stone molds. This report aims to introduce a complete digital workflow to construct a nasal prosthesis and compare it to the conventional workflow of a patient requiring a nasal prosthesis. A computer tomography scan showing the defect was exported to specialized software to create 3D reconstructions of the patient's face and underlying bone. The nose was digitally designed restoring facial esthetics, anatomy, shape, and skin color. Different skin tones were digitally matched to skin tissues adjacent to the defect area using the Spectromatch system. The design was 3D printed in flexible and colorful material at 16 µm resolution using a 3D printer. External color pigmentations were applied to the nose for optimum esthetics, and the prosthetic nose was sealed in silicone and left to heat polymerize for 15 minutes. The prosthetic nose was retained in place using biomedical adhesive, and the patient was pleased with it. This report proposes a complete digital workflow to directly design and fabricate a prosthetic nose of acceptable esthetics. Such a workflow can lead to enhanced prosthesis reproducibility and acceptability and may become an effective treatment option for treatment of patients with facial defects.
