Evaluation of Intermediate Visual Outcomes in Eyes Implanted with Bilateral Advanced Monofocal Intraocular Lens Targeting for Mini-Monovision and Its Association with Age and Corneal Asphericity.

To assess the visualoutcomes in patients bilaterally implanted with novel Clareon® intraocular lens when targeting mini monovision post-operatively. The study was conducted at Laxmi Eye Institute; itis a tertiary care eye institution in Panvel, India. This is an investigator initiated, prospective, single-centre longitudinal study of 45 patients to assess the visual outcomes in patients who were implanted with Clareon ® IOL bilaterally. Patients with corneal astigmatism of ≤0.75 D who underwent bilateral cataract surgery with pseudophakic mini-monovision and implanted with novel Clareon® intraocular lens were included. Patients having post op manifest refraction >±0.25 D in the dominant eye and <-0.5 D or >-0.75 D in the non-dominant eye were excluded. The main study outcomes were assessed at 1 and 3 months; itincluded uncorrected visual acuities assessment, defocus curve, and patient reported spectacle use. The mean (SD) binocular distance corrected intermediate visual acuity at 3 months was 0.22 (0.09) LogMAR. At 3 months, 54% of patients enjoyed 0.4 LogMAR or better BUCNVA. The defocus curve showed good distance and intermediate visual acuity with >0.2 LogMAR vision from +0.50 D to -1.50 D. We found a positive correlation between the Q value of the dominant eye and the BCIVA at 3 months postoperatively, however it was not statistically significant. The Q value was more negative when the intermediate vision was closer to 0 LogMAR. Post operatively, at3 months,95% patients did not need glasses for distance and intermediate vision and 73% of patients were comfortable for intermediate vision without glasses all the time. Mini-monovision with Clareon® monofocal IOL implantation can offer overall satisfactory vision for far and intermediate distances with minimal need for use of spectacles for near vision.

Various local facial flaps for traumatic and surgical facial defects

Aims: This study aimed to analyze the various modalities of reconstruction using local flaps for facial defects that occur after surgical excision and trauma and their advantages and disadvantages. Materials and Methods: A retrospective analysis was performed for 65 cases (age group from 20-45 years) with small to medium-sized facial defects from various causes over a period of 5 years. Patients with immunodeficiency, terminal illnesses and head injury were excluded. Treatment methods depended on size and location of defect. Results: Of the 65 patients, 15 had nasolabial flaps, 6 had V-Y advancement flaps, 3 had cheek advancement flaps, 2 had forehead flaps, 2 had Limberg flaps, 20 had fillet flaps and 17 were bilateral advancement flaps. Postoperatively none developed complications with acceptable functional and aesthetic outcome which were excellent in 55 patients, good in 5 patients and fair in 5 patients after 6 months of follow up. Conclusions: Local facial flaps are a simple, easy and versatile option to reconstruct small to medium sized facial defects and provides a good match with adjacent skin thus providing good aesthetic and functional results along with fast recovery.

The Intermarium As a Pivotal Geopolitical Buzzword

This article focuses on historical and contemporary connotations of the Intermarium concept—Ukrainian and Polish academic and political thought on how to organize and govern the space between the Baltic and Black seas—employing the ideas of Józef Piłsudski, Józef Beck, Michał Czajkowski (Mykhailo Chaikovs'kyi), Mykhailo Drahomanov, members of the Brotherhood of Saints Cyril and Methodius, and other intellectuals. In this context, it traces Ukraine’s and Poland’s attempts to construct Intermarium-type intergovernmental frameworks in the aftermath of the Cold War. It also examines the current stage of Ukrainian-Polish co-operation—the latter being regarded by Intermarium founding fathers as a vital precondition for this framework to be realized. In this respect, the article considers bilateral advancements in political, economic, cultural, and security spheres. As the emergence of a Ukrainian-Polish institutionalized linchpin is impossible in the contemporary geopolitical architecture, the article proposes that the term “Intermarium” has become ambiguous. If by chance the Intermarium comes into being as a defensive alliance today, it might bring more harm than benefit to the regional security.

Bilateral Advancement Heart-Shaped Anoplasty for Severe Anal Stenosis: A New technique

AbstractSevere anal stenosis is an unusual complication following hemorrhoidectomy but leads to severe morbidity. The treatment of severe anal stenosis is usually some type of anoplasty. We designed a heart-shaped bilateral advancement anoplasty for the correction of this condition. We carried out this operation in five patients with successful results.

The impact of advanced age-related macular degeneration on the National Eye Institute's Visual Function Questionnaire-25.

To assess visual function among patients diagnosed with age-related macular degeneration (AMD) by stage of disease and laterality. This is a cross-sectional cohort study of 739 AMD patients and their responses to the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25) at time of study enrolment. Patients with AMD were categorized into Early/Intermediate AMD and three groups of advanced AMD: (i) neovascular AMD (NV), (ii) geographic atrophy (GA) and (iii) Both Advanced forms. These three advanced stages were further stratified into unilateral or bilateral advanced disease. Mean composite scores and subscale scores for 12 different areas were based on a 100-point scale with the lowest and highest possible scores set at 0 and 100, respectively. Scores for the advanced AMD groups were compared with Early/Intermediate AMD using general linear modelling. A total of 739 AMD patients (294 Early/Intermediate, 115 GA, 168 NVAMD and 162 Both Advanced) were included in the analysis. Mean composite scores were highest among Early/Intermediate patients (89.9), followed by patients diagnosed with unilateral disease in the Both Advanced (88.0) and NV (86.1) groups. Mean composite scores were similar for bilateral NV (82.9) and unilateral GA (81.7), and mean scores were lowest for the bilateral GA (71.3) and bilateral Both Advanced (68.5) groups. In general, this pattern persisted across the twelve subscales as well. Subscale scores ranged from a low of 35.1 for driving among bilateral Both Advanced patients to a high of 99.2 for colour vision among patients with unilateral Both Advanced. Overall, patients with unilateral advanced disease consistently had higher mean scores than their bilateral counterparts. The largest difference was 19.5 composite score points between the unilateral and bilateral Both Advanced groups, there was a difference of 10.4 points between the GA groups, and a relatively small difference of 3.2 points between the NV groups. We found large differences in visual function as reported from the VFQ-25 across the different types of advanced stage AMD groups and number of eyes affected with advanced AMD. These findings demonstrate the importance of accounting for the type and number of eyes affected by advanced stage AMD.

Validating the Asher-McDade score to assess facial aesthetic outcomes in 22 consecutive complete bilateral cleft lip repairs

Most scoring systems used to assess facial aesthetics in cleft patients tend to lack consistency, and the absence of an internationally agreed system makes comparison challenging. The most widely used and validated tool is the five-point Asher-McDade index. We note that there are currently no reports (to our knowledge) of its use for scoring outcomes after bilateral cleft lip repair. To validate it for this use, the aim was to describe the outcomes of 22 consecutive bilateral cleft lip repairs assessed using this scale. A retrospective review was undertaken of 22 consecutive patients with bilateral cleft lip repairs performed at our centre. Each patient underwent bilateral advancement rotation repair with a vomer flap on one side at three months followed by repair of the remaining hard palate and an intravelar veloplasty three months later. Standardised photographs were taken five years after repair and were cropped to isolate the nasolabial component. Eleven members of the cleft multidisciplinary team were asked to rate each image on a five-point Likert scale. Statistical analysis was performed using a two-way ANOVA test and intraclass correlation coefficient to interrogate intraobserver and interobserver variance. A total of 22 consecutive patients with complete bilateral cleft lips were photographed. The overall mean (range) score for the repairs was 3.2 (4.3 - 1.8). Two-way ANOVA demonstrated that inter-rater variability accounted for just over 10% (11.23% of the total variance, p < 0.0001). As predicted, the single biggest factor affecting score variability was the patient’s appearance, which accounted for 44.51% of the total variance between scores (p < 0.0001). Intraobserver variance was not found to be significant, accounting for 0.33% of the total variance (p = 0.0006). We demonstrate that the Asher-McDade scoring system is a valid tool to use when assessing bilateral cleft lip repairs. Variance in the patient’s score was significantly related to a true difference in appearance, with only a small percentage of differences being due to intraobserver and interobserver variation.

Penile and scrotal defects post-Fournier gangrene: reconstructive options and challenges in resource limited settings

Introduction: Penile and scrotal defects following necrotizing fasciitis (Fournier gangrene) of the perineum in males can be a source of great morbidity and psychological concern to the patients inflicted with such a problem. In severe cases, it can result in mortality. Reconstruction of extensive defects/ulcers can be challenging in resource limited settings due to limited availability of tools such as doppler ultrasound/stethoscope, loupes, and operating microscopes for microsurgical procedures. Fournier gangrene is usually managed by the urologists in most centers in collaboration with the plastic surgeons for reconstruction of more extensive defects. Objective: The aim of the study was to review the penile and reconstructive options deployed for post-Fournier gangrene patients over a 3-year period (April 2017 to March 2020) in a tertiary hospital setting highlighting options utilized, indications for the respective options, and challenges encountered. Methodology: Case notes of Fournier gangrene patients offered penoscrotal reconstruction by the urology and plastic surgical teams within the period were retrieved, reviewed, and relevant data useful in achieving the above objectives extracted for analysis. Clinical photographs of some of the patients were included for illustration. Results: Twenty patients (20) that met the inclusion criteria were reviewed. Fourteen (70%) had defects involving both the scrotum and the penis, five (25%) involved the scrotum alone, while one (5%) had defect on the penis alone. Four (20%) had diabetes mellitus, three (15%) had HIV infection, and two (10%) had hypertension. Seventy percent (14) of the patients had secondary wound repair by direct closure, 5% (one) had split skin grafting alone, 5% (one) had a combination of split skin grafting and local advancement flap, and 20% (four) required the use of available locoregional flap [three being bilateral scrotal advancement flaps and one being bilateral pudendal thigh (Singapore) flap]. Healing was satisfactory in all the patients although two of them (10%) had surgical site infection whereas one (5%) had mild wound dehiscence, but all healed within 2 weeks. Conclusion: Post-Fournier gangrene defects can be reconstructed using several options, the choice of which is dependent on the size of the defect, elasticity of residual scrotal skin, status of defined locoregional pedicles, availability of modern diagnostic and operating equipment, and expertise of the surgeon. Collaboration between the urologists and the plastic surgeons is recommended for optimal outcome.

Large versus small mandibular counterclockwise rotation during bimaxillary surgical correction of class II deformities-a retrospective CBCT study on skeletal stability.

Postsurgical skeletal relapse is a concern for class II deformities corrected with counterclockwise rotation of the occlusal plane. Therefore, the aim of this study was to compare the skeletal stability between large and small counterclockwise rotational advancement of the mandible in patients with skeletal class II deformity. This retrospective study included 50 adult patients with skeletal class II deformity corrected by Le Fort I setback and bilateral sagittal split osteotomy counterclockwise rotational advancement. Patients were divided into two groups, according to the amount of counterclockwise rotation: small rotation (n = 25) and large rotation (n = 25). Serial cone beam computed tomography scans were analyzed to identify skeletal and dental position from presurgery to at least 12months postsurgery. Changes in the facial skeleton (maxilla and mandible) and teeth (central incisor and first molar) were determined for six skeletal and four dental landmarks by measures before treatment (T0) and 1week postsurgery (T1), and from T1 to at least 12months postsurgery (T2). A relapse was found both after large and small rotational advancement of the mandible (pogonion: 1.0 (2.4) mm and 1.4 (3.0) mm, respectively). The result was statistically significant (both p< 0.05) and was with less than 1.5mm clinically acceptable. There were no between-group differences in the postsurgical horizontal and vertical mandibular stability. The results suggest that counterclockwise rotational advancement of the mandible using bilateral sagittal split osteotomy is a clinically stable procedure. The amount of rotation does not affect the postsurgical stability of the mandible. The findings help clinicians better understand the surgical and postsurgical changes of the skeleton and teeth after counterclockwise rotational advancement of the mandible for class II deformity.

Analysis of Immediate versus Delayed Sternal Reconstruction with Pectoralis Major Advancement Versus Turnover Muscle Flaps.

The pectoralis major muscle flap is a versatile reconstructive option for deep sternal wound infections (DSWI). The timing and surgical technique of bilateral pectoralis major muscle advancement flaps versus unilateral pectoralis major muscle turnover and unilateral pectoralis major muscle advancement flap on patient outcomes remain to be elucidated. The purpose of this investigation was to compare timing, immediate versus delayed reconstruction, and the surgical technique in patients with deep sternal wounds infections on patient outcomes. A retrospective review of patients who underwent sternal reconstruction with pectoralis major muscle was conducted. Patients diagnosed with DSWI after undergoing cardiac surgery were included for analysis. Patients were divided by flap timing and flap type for analyses. Bivariate tests were performed to compare patient clinical characteristics. Outcomes of interest were rates of postoperative complications, same admission mortality, reoperation, readmission, operating room time, and length of stay. A total of 88 patients were included for analyses (n = 57 bilateral advancement, n = 31 unilateral advancement with unilateral turnover; n = 62 immediate, and n = 26 delayed). Baseline characteristics did not differ between groups of flap type or timing. When postoperative complication rates were compared, the rate of tissue necrosis was significantly greater in patients with unilateral advancement with unilateral turnover flaps (n = 6 [19.4%]) compared with bilateral advancement flaps (n = 2 [3.5%]; p = 0.021). Mortality during admission did not differ with respect to flap type but differed significantly with respect to flap timing (immediate n = 7 [11.3%], delayed n = 9 [34.6%]; p = 0.015). Length of stay differed significantly by both type and timing (type: bilateral advancement = 26.9 ± 22.6 days, unilateral turnover = 38.0 ± 26.7 days, p = 0.042; timing: immediate = 26.8 ± 22.1 days, delayed = 40.2 ± 27.8, p = 0.019). Patients who underwent pectoralis major muscle advancement flaps had lower incidence of tissue necrosis. Furthermore, the timing of immediate sternal reconstruction was associated with a decreased hospital length of stay.

Chondrocutaneous Bilateral Advancement Flap with Postoperative Radiation Therapy for a Helical Rim Keloid.

Keloids can be recalcitrant, and a well-planned treatment strategy is essential. Multiple ear piercings have recently become popular, particularly among younger age groups. Management of keloids that develop after piercing of the ear cartilage may be particularly problematic. Helical rim keloids are difficult to excise because of the complex, three-dimensional, cartilaginous structure of the helix and its thin and tightly adherent covering layer of skin. The chondrocutaneous advancement flap introduced by Antia and Buch may be a useful reconstructive option for a helical rim keloid after marginal loss of a segment of the helix as a result of trauma, a burn, or excision of a malignant tumor. However, this technique is limited to wounds that involve only the helix. In this technical note, we describe the use of a chondrocutaneous bilateral advancement flap with postoperative radiation therapy to treat a more invasive and relatively large keloid on the scapha. This technique is straightforward and safe in terms of preserving the blood supply. The addition of adjuvant radiation therapy can help to decrease the risk of recurrence and preserve the morphological structure of the ear and patient satisfaction.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

A New Technique for Reconstruction of Medium-Sized Eyelid Defects (A Modification of Tessier Nasojugal Flap).

Eyelid reconstructions are considered challenging surgical procedures, which are mostly performed due to trauma, tumor resections, and congenital defects. Several techniques can be used to reconstruct the lower eyelid defects. In this study, the authors aimed to introduce a new single-step technique for the reconstruction of medium-sized lower eyelid defects while preventing ectropion. A modified nasojugal flap was designed and harvested after making a complete incision. A dermal extension from the nasolabial area was added to the end of the nasojugal flap. A tunnel was created under the orbicularis oculi muscle, and the dermal tail was passed through this tunnel toward the lateral canthus. The flap was fixed in its new position by suturing. The defect in the nasojugal area was repaired by bilateral advancement of the surrounding tissue. The recovery of the patients was followed up for 6 months, which included assessment of the eyelid position and donor site morbidity. A total of four patients with an age range of 64 ± 8 years who suffered from basal cell carcinoma were treated using the technique introduced in this study. No ectropion or abnormal eyelid position nor donor site morbidity was observed during the follow-up period. Reconstruction of a medium-sized lower eyelid defect using nasolabial flap with local modification combined with orbital canthus fixation resulted in appropriate functional and cosmetic outcomes and limited the risk of complications and morbidity.

Microscopic approach for repairing nasal septal perforations using bilateral advancement flaps.

Septal perforations consist in an anatomic defect of the mucosal, cartilaginous and/or bone tissues of the nasal septum. A huge variety of approaches and techniques for nasal perforation repair have been reported. Between January 2008 and January 2017, 38 patients were treated for nasal septal perforation in Department of Otorhinolaryngology Head and Neck Surgery, Fundación Jiménez Díaz University Hospital, Madrid, Spain. A novel approach is presented based on microscope. Septal perforation closure was performed with endonasal bilateral advancement flaps-established technique and autologous cartilage and muscle temporal fascia grafts. We performed a retrospective review of closure rates and complications. A postoperative follow-up of at least 12months was performed in 37 patients. The mean size of perforation was 1.33cm. After the withdrawal of the silicone splints, perforations were completely closed in all cases. However, during the follow-up, four patients resulted in a reperforation, so our closure rate was 89.19%. For all cases, symptoms related to septal defect were solved. Only one case was reported of local infections that was resolved with antibiotics in a few days. Microscopic approach of septal perforation closure using bilateral advancement flaps can be an affordable technique with a high percent of success and low rate of complications.

Basic skin surgery interactive simulation: system description and randomised educational trial

BackgroundLearning the skills required for open surgery is essential for trainee progression towards more advanced technical procedures. Simulation supports skill enhancement at a time when exposure to actual surgical procedures and traditional apprentice-based teaching has declined. The proliferation of smartphone and tablet devices with rich, touch sensitive displays and increasing processing power makes a compelling argument for expanding accessibility further by development of mobile virtual simulations for training on demand in any setting, at any time.We present a tablet-based mobile simulation App for educating surgical trainees in the planning and surgical procedures involved in facial lesion resection and local skin flap surgery.MethodsNovel algorithms were developed and modules included in a mobile simulation App to teach concepts required for three defect reconstruction techniques: elliptical closure, bilateral advancement (H flap) and the semi-circular rotation flap, with additional resources such as videos and formal guidelines made available at relevant points in the simulation. A randomised educational trial was conducted using the mobile simulation App with 18 medical students that were divided equally into two groups: the intervention group learning using the new mobile simulation App, and a control group, undergoing traditional text-based self-study. The students were then assessed on knowledge and skills’ acquisition through an MCQ and a task analysis score.ResultsThere was a statistically significant difference between the scores of students in the intervention group and the students in the non-intervention group in both forms of assessment, with an average multiple-choice assessment score of 62.95% points versus 56.73%, respectively (p = 0.0285), and an average task analysis score of 3.53 versus 2.58, respectively (p = 0.0139).ConclusionsTouch-based simulation provided an efficient and superior method of learning three different local flap techniques for facial soft tissue reconstruction, and helped recalling steps involved in the surgery in a fluid manner that also improved task performance.
