Background. Eyes are an important component of the face and vital organs of vision. Eye loss can be caused by congenital defects, trauma, or tumor. Loss of an eye produces physical abnormalities that pose a psychological burden on the patient, as well as visual function damage. An ocular prosthesis is an artificial maxillofacial prosthesis to replace the lost eye. Case summary. A 54-year-old man consults at the Prosthodontics Specialist Universitas Airlangga Dental Hospital for an eye prosthesis. The patient did not have the right eyeball since birth. Soft tissue around the eye is normal, including the palpebral muscles. Case management. An impression was made using a custom tray and alginate in the defect area, followed by filling the impression with gypsum type 3 to get a working model, from which a wax model is made and adjusted to the patient. After that, sclera and ocular acrylic prostheses are made on the basis of an adjusted wax model. The prosthesis is then polished and colored according to the contralateral eye. Then the prosthesis is delivered to the patient. Conclusion. The hollow custom-made eye prosthesis can be considered in the treatment of anophthalmia. It is able to improve the patient's psychological and emotional status.

Custom Ocular Prosthesis

Physical defects that compromise appearance or function, which prevent an individual from leading a normal life, usually prompt the individual to seek treatment that will reinstate acceptable normalcy. The loss of an eye impairs the patient’s visual function, yet also results in a noticeable deformity. Prosthesis should be provided as soon as possible to raise the spirits and ease the mind of the afflicted. An ocular prosthesis is a maxillofacial prosthesis that artificially replaces an eye missing as a result of trauma, surgery, or congenital absence. A custom ocular prosthesis has advantage of close adaptation to the tissue bed, provides maximum comfort and restores full physiological function to the accessory organs of the eye.

Trigeminal neuralgia is a chronic condition which produces severe pain involving a part of the face. The aim of this study was to evaluate the prevalence of trigeminal neuralgia among dental patients visiting a dental institution. This retrospective study included patients who were diagnosed with trigeminal neuralgia from July 2019 to March 2020 in a dental hospital. The digital case records of all patients were retrieved and details were recorded, which included the clinical, radiographic examination and treatment undergone by the patients. Variables such as age, gender, site of involvement were also retrieved from the case records. Data were tabulated and statistically analysed using IBM SPSS version 23.0 and results obtained. P value < 0.05 was considered statistically significant. In the present study, out of 28 patients, males (53.6%) were more affected by trigeminal neuralgia than females (46.4%) with a higher prevalence on the right side (57.1%). Quadrant I (25%) and combination of quadrant II and quadrant III (25%) were most commonly involved by this condition. No statistically significant association was found between age and quadrant affected; gender and quadrant affected. (p>0.05). It can be concluded from our study that males were more affected with trigeminal neuralgia, the majority involving the right side of the face and seen commonly among the elderly age group. Dentists must be aware of the clinical features of trigeminal neuralgia for accurate diagnosis and early initiation of prompt treatment to avoid untoward complications.

Artificial Prosthesis

An artificial eye is a prosthetic unit that serves to replace the lost orbital volume when the living eye is either shrunken or surgically removed. The custom prostheses are made to adapt to the contour of the orbital tissues and eyelids, and colored to match the companion eye. Although implant eye prosthesis has a superior outcome, due to economic factors it may not be advisable in all patients. Therefore, a custom-made ocular prosthesis is an excellent alternative. But the common failing of such custom made ocular prosthesis has been that there is no or very limited mobility of the eye prosthesis, which marks it as what it is, an artificial prosthesis. In the following clinical report it will be demonstrated with the help of a patient the use of a movable custom made ocular prosthesis, which shows marked mobility.

Purpose: Recurrent contracted sockets are complex situations where previous surgeries have failed, disabling the wear of an ocular prosthesis. A combined method of surgery and long-term fixation using custom-made, three-dimensional (3D) printed conformers is evaluated. Methods: Retrospective case series of nine patients with recurrent excessive socket contraction and inability to wear a prosthesis, caused by chemical burns ( n = 3), fireworks ( n = 3), trauma ( n = 2) and enucleation and radiotherapy at childhood due to optic nerve glioma ( n = 1) with three average previous socket surgeries (range 2–6). Treatment consisted of a buccal mucosal graft and personalized 3D-printed conformer designed to be fixated to the periosteum and tarsal plates for minimal 2 months. Primary outcome was the retention of an ocular prosthesis. Secondary outcome was the need for additional surgeries. Results: Outcomes were measured at final follow-up between 7 and 36 months postoperatively (mean 20 months). Eight cases were able to wear an ocular prosthesis after 2 months. Three cases initially treated for only the upper or only the lower fornix needed subsequent surgery for the opposite fornix for functional reasons. Two cases had later surgery for cosmetic improvement of upper eyelid position. Despite pre-existing lid abnormalities (scar, entropion, lash deficiency), cosmetic outcome was judged highly acceptable in six cases because of symmetric contour and volume, and reasonably acceptable in the remaining two. Conclusions: Buccal mucosal transplant fixated with a personalized 3D-designed conformer enables retention of a well-fitted ocular prosthesis in previously failed socket surgeries. Initial treatment of both upper and lower fornices is recommended to avoid subsequent surgeries for functional reasons.

AbstractThe right ventricle´s (RV) characteristics—thin walls and trabeculation—make it challenging to evaluate extracellular volume (ECV). We aimed to assess the feasibility of RV ECV measurements in congenital heart disease (CHD), and to introduce a novel ECV analysis tool. Patients (n = 39) and healthy controls (n = 17) underwent cardiovascular magnetic resonance T1 mapping in midventricular short axis (SAX) and transverse orientation (TRANS). Regions of interest (ROIs) were evaluated with regard to image quality and maximum RV wall thickness per ROI in pixels. ECV from plane ROIs was compared with values obtained with a custom-made tool that derives the mean T1 values from a “line of interest” (LOI) centered in the RV wall. In CHD, average image quality was good (no artifacts in the RV, good contrast between blood/myocardium), and RV wall thickness was 1–2 pixels. RV ECV was not quantifiable in 4/39 patients due to insufficient contrast or wall thickness < 1 pixel. RV myocardium tended to be more clearly delineated in SAX than TRANS. ECV from ROIs and corresponding LOIs correlated strongly in both directions (SAX/TRANS: r = 0.97/0.87, p < 0.001, respectively). In conclusion, RV ECV can be assessed if image quality allows sufficient distinction between myocardium and blood, and RV wall thickness per ROI is ≥ 1 pixel. T1 maps in SAX are recommended for RV ECV analysis. LOI application simplifies RV ECV measurements.

Abstract Background The biatrial trans-septal approach (BTSa) ameliorates mitral valve (MV) exposure in difficult cases when routine left atriotomy doesnt"t allow it. Main steps are an oblique incision on the right atrium (RA), reaching medially the right pulmonary veins (PV), a septal incision from the fossa ovalis, extended up to reach the first incision, then on the left atrium (LA). Purpose We aim to study the arrhythmic burden in this post-surgical context, focusing on atrial tachycardia (AT), to investigate the complexity of several possible circuits. Methods All patients (&gt;18yo) with previous MV surgery via BTSa for MV repair or replacement, who underwent ablation of AT from January 2017 to September 2019, were enrolled. Patients ablated for persistent or paroxysmal AF, or with AF during the index procedure were excluded. Patients with associated surgery on other valves or congenital defects, coronary, surgical or percutaneous rhythm interventions weren’t excluded. Electroanatomical mapping was created using 2 different high-density mapping system. Substrate and activation map and radio-frequency (RF) ablation (25-50W, Ablation Index target 400) were realized. Cartographies were analysed to evaluate AT re-entry circuit, critical isthmus (CI) location and characterization, atrial vulnerability. Procedural outcomes (AT termination, sinus rhythm (SR) restoration, anti-arrhythmic drugs (AAD) withdrawal), and peri-procedural complications were also evaluated. Results We enrolled 49 patients (median age 57 ± 15), finding a maximum of 5 AT per procedure (2 ± 1). A total of 112 AT were mapped: the majority (72%) were persistent AT, 8,2% common atrial flutter. Cycle length was 314 ± 74 msec, with proximal-distal activation of coronary sinus (78%). A multiple re-entry circuit was observed in 70% of index AT. We identified 152 critical isthmus (maximum 5 per procedure). Only 27,9% of our patients had a single CI; CTI was the most frequent one (n = 37), envolved in 33% of all AT, while BTS scars altogether were envolved in 65% AT. A complete AT circuit was mapped in the RA, the LA and both atria in respectively 49%, 11,5% and 39%AT. The distribution of CIs is shown in figure 1. Biatrial and left AT leads to superior procedure, RF and fluoroscopy duration (p &lt;0,05). SR was restored in 93,4%of patients, requiring a DC shock in 4 cases. Immediate AAD withdrawal was achieved after 41%procedures. No pericardial, oesophageal, vascular or phrenic complication occurred. 4 pace-maker implantations were realized because of 3 interatrial, 2 AV block and a sinus node dysfunction. Conclusions AT occurring after a BTSa have a high prevalence of multiple re-entry circuits with multiple critical isthmus. Ablation in this context is feasible and safe but often requires a left atrial access. Mapping of both atria should be considered to identify critical isthmus and tailored ablation strategy.

Cavopulmonary Connection

Background—The total cavopulmonary connection (TCPC), a palliative correction for congenital defects of the right heart, is based on the corrective technique developed by Fontan and Baudet. Research into the TCPC has primarily focused on reducing power loss through the connection as a means to improve patient longevity and quality of life. The goal of our study is to investigate the efficacy of including a caval offset on the hemodynamics and, ultimately, power loss of a connection. As well, we will quantify the effect of vessel wall compliance on these factors and, in addition, the distribution of hepatic blood to the lungs. Methods—We employed a computational fluid dynamic model of blood flow in the TCPC that includes both the non-Newtonian shear thinning characteristics of blood and the nonlinear compliance of vessel tissue. Results—Power loss in the rigid-walled simulations decayed exponentially as caval offset increased. The compliant-walled results, however, showed that after an initial substantial decrease in power loss for offsets up to half the caval diameter, power loss increased slightly again. We also found only minimal mixing in both simulations of all offset models. Conclusions—The increase in power loss beyond an offset of half the caval diameter was due to an increase in the kinetic contribution. Reduced caval flow mixing, on the other hand, was due to the formation of a pressure head in the offset region which acts as a barrier to flow.
