Aptis Distal Radioulnar Joint Arthroplasty: A Multicenter Evaluation of Functional Outcomes, Complications, and Patient Satisfaction.

Background The Aptis distal radioulnar joint (DRUJ) implant has been commonly used to replace the DRUJ and restore wrist function in patients with a severely destroyed DRUJ. Objective Promising results have been described in the literature. However, the clinical results in a multicenter setting are sparse and variable. This study evaluates the short- to midterm clinical results of 53 patients with a (mean) follow-up of 51 months. Patients and Methods Fifty-three patients (59 implants) treated between 2011 and 2020 in three different institutions were retrospectively identified in a prospectively collected database. The main indication for Aptis DRUJ arthroplasty was a destroyed DRUJ and gross distal radioulnar instability and isolated DRUJ osteoarthritis. Functional outcome, complications, and patient satisfaction were evaluated. Patients completed the Patient-Rated Wrist Evaluation (PRWE) questionnaire and an additional questionnaire about patient satisfaction and return to hobby/work. Results Implant survival was 92%, the surgical follow-up showed many complications (64,4%), and revision surgery was needed frequently (40.7%). In 13 cases, the follow-up was longer than 5 years. Three reimplantations had to be performed and two implants were permanently explanted. In spite of this all, wrist and forearm motion as well as pain reduction was adequate and patient satisfaction was reasonable (72.2%). Conclusion The Aptis DRUJ arthroplasty is a viable option that can provide adequate wrist and forearm function after secure patient selection and surgical placement of the implant in the wrist with a good bone stock of the radius. The complication rate was found to be high, yet patient satisfaction was reasonable. In the case of secondary surgery, additional surgery seems to be needed. For primary surgery, the implant seems to be successful without complications. Different complications have been described, but further analysis is warranted to find the causes of complications and to objectify the performance of the Aptis DRUJ implant. Level of Evidence IV.

#MadelungDeformity: Insights Into a Rare Congenital Difference Using Social Media.

BACKGROUND: Madelung deformity is a rare congenital hand difference with little known regarding the patient perspective. In this cross-sectional survey study, we harnessed the global reach of social media to understand the clinical spectrum of Madelung deformity and its impact on physical, mental, and social health. METHODS: A survey was developed based on a previously published protocol and multiple Patient-Reported Outcomes Measurement Information System (PROMIS) short forms. The survey was distributed on several Madelung deformity communities on Facebook and Instagram. T-scores were calculated, interpreted, and compared between patients who underwent surgery and those who did not. Correlations between scores were calculated using the Spearman rank correlation coefficient. RESULTS: Mean PROMIS scores for adults were as follows: pain intensity, 4.9 ± 2.8; pain interference, 57.6 ± 10.0; upper extremity, 35.2 ± 8.1; depression, 53.8 ± 11.1; anxiety, 55.4 ± 11.4; and ability to participate in social roles and activities, 42.5 ± 7.7. Mean scores for children were as follows: pain intensity, 5.0 ± 2.8; pain interference, 55.7 ± 11.3; upper extremity function, 24.6 ± 10.4; depressive symptoms, 57.7 ± 11.3; anxiety, 57.3 ± 11.9; and peer relationships, 42.2 ± 10.3. CONCLUSIONS: Madelung deformity has significant effects on patients' physical, mental, and social well-being, even after surgical treatment. Using social media, we were able to compensate for Madelung deformity's rarity by engaging an international audience, demonstrating the feasibility to conduct research through it, and providing a global perspective of the disease entity.

Madelung Deformity: Radioscapholunate Arthrodesis With a Neo-DRUJ.

BACKGROUND: Madelung deformity is a rare wrist anomaly that causes considerable pain while restricting function. In this study, we describe a radioscapholunate (RSL) arthrodesis with a neo-distal radioulnar joint (DRUJ) in Madelung deformity patients with an abnormal sigmoid notch and compare results to patients after a reverse wedge osteotomy. METHODS: Six wrists underwent RSL arthrodesis with a neo-DRUJ in a two-phase approach: (1) modified RSL arthrodesis with triquetrectomy; and (2) distal scaphoidectomy. Seven wrists underwent a reverse wedge osteotomy procedure. RESULTS: There were no differences found in postoperative pain, grip strength, or range of motion (ROM), apart from extension, which was decreased after RSL arthrodesis with a neo-DRUJ. Quality of life and Michigan Hand Outcomes Questionnaire scores were similar. CONCLUSIONS: Although clinical outcome parameters are not different among the two groups, the RSL arthrodesis with construction of a neo-DRUJ could prove a valid treatment option for a subset of patients with a severely affected sigmoid notch.

Quantitative Fluorescence Imaging of Perfusion-An Algorithm to Predict Anastomotic Leakage.

This study tests fluorescence imaging-derived quantitative parameters for perfusion evaluation of the gastric tube during surgery and correlates these parameters with patient outcomes in terms of anastomotic leakage. Poor fundus perfusion is seen as a major factor for the development of anastomotic leakage and strictures. Fluorescence perfusion imaging may reduce the incidence of complications. Parameters for the quantification of the fluorescence signal are still lacking. Quantitative parameters in terms of maximal intensity, mean slope and influx timepoint were tested for significant differences between four perfusion areas of the gastric tube in 22 patients with a repeated ANOVA test. These parameters were compared with patient outcomes. Maximal intensity, mean slope and influx timepoint were significantly different between the base of the gastric tube and the fundus (p < 0.0001). Patients who developed anastomotic leakage showed a mean slope of almost 0 in Location 4. The distance of the demarcation of ICG to the fundus was significantly higher in the three patients who developed anastomotic leakage (p < 0.0001). This study presents quantitative intra-operative perfusion imaging with fluorescence. Quantification of the fluorescence signal allows for early risk stratification of necrosis.

Comparison of an oblique single cut rotation osteotomy with a novel 3D computer-assisted oblique double cut alignment approach.

An oblique double-cut rotation osteotomy (ODCRO) enables correcting a complex bone deformation by aligning, in 3D, the distal, middle and proximal bone segments with a target bone, without intersegmental gaps. We propose virtual preoperative planning of an ODCRO. To minimize a residual translation error, we use an optimization algorithm and optimize towards bone length, alignment in the transverse direction, or a balanced reconstruction. We compare the residual alignment error with an oblique single-cut rotation osteotomy using 15 complex bone deformations. The single-cut approach was not feasible in 5 cases, whereas the ODCRO procedure was feasible in all cases. The residual alignment error was smaller for the ODCRO than for the single-cut approach except for one case. In a subset for length reconstruction, the length error of 7.3-21.3 mm was restored to 0.0 mm in 4 of 5 cases, although at the cost of an increased transverse translation. The proposed method renders planning an ODCRO feasible and helps restoring bone alignment and lengthening better than an oblique single-cut rotation osteotomy. Awareness of the challenges and possibilities in preoperative planning of an ODCRO will be of value for future alignment surgery and for patients.

Variation in Treatment for Trapeziometacarpal Arthrosis.

BACKGROUND: Treatment recommendations for trapeziometacarpal (TMC) arthrosis are highly variable from surgeon to surgeon. This study addressed the influence of viewing radiographs on a decision to offer surgery for TMC arthrosis. METHODS: In an online survey, 92 hand surgeons viewed clinical scenarios and were asked if they would offer surgery to 30 patients with TMC arthrosis. Forty-two observers were randomly assigned to review clinical information alone and 50 to review clinical information as well as radiographs. The degree of limitation of daily activities, time since diagnosis, prior treatment, pain with grind, crepitation with grind, and metacarpal adduction with metacarpophalangeal hyperextension were randomized for each patient scenario to determine the influence of these factors on offers of surgery. A cross-classified binary logistic multilevel regression analysis identified factors associated with surgeon offer of surgery. RESULTS: Surgeons were more likely to offer surgery when they viewed radiographs (42% vs. 32%, P = 0.01). Other factors associated variation in offer of surgery included greater limitation of daily activities, symptoms for a year, prior splint or injection, deformity of the metacarpophalangeal joint. Factors not associated included limb dominance, prominence of the TMC joint, crepitation with the grind test, and pinch and grip strength. CONCLUSION: Surgeons that view radiographs are more likely to offer surgery to people with TMC arthrosis. urgeons are also more likely to offer surgery when people do not adapt with time and nonoperative treatment. Given the notable influence of surgeon bias, and the potential for surgeon and patient impatience with the adaptation process, methods for increasing patient participation in the decision-making process merit additional attention and study.

Carpal Kinematics in Madelung Deformity.

PURPOSE: Various skeletal and soft tissue abnormalities have been identified in Madelung deformity and have been hypothesized to play a causal role in its progressive symptomatology; however, our pathological understanding of these changes remains limited. In this study, we biomechanically assessed the Madelung deformity wrist, using 4-dimensional computed tomography imaging. METHODS: Nine Madelung deformity wrists (5 patients; age, 24 ± 5 y) and 18 healthy wrists (9 volunteers; age, 28 ± 3 y) underwent 4-dimensional imaging during flexion-extension motion and radioulnar deviation. Carpal kinematics and radiocarpal joint parameters were quantified and compared. RESULTS: In Madelung deformity wrists, significantly decreased rotation was seen in the lunate (-4.6°) and the triquetrum (-4.8°) during flexion-extension motion. During radioulnar deviation, significant decreases were visible in lunate bone translation (-0.7 mm), triquetrum bone translation (-0.6 mm), and triquetrum bone rotation (-1.9°). Patients had significantly decreased articulating surface areas of the scaphoid (1.4 ± 0.2 cm2 versus 1.6 ± 0.2 cm2) and lunate (1.2 ± 0.4 cm2 versus 1.5 ± 0.3 cm2) fossa, and significantly increased radioscaphoid (1.3 ± 0.1 mm versus 1.2 ± 0.1 mm) and radiolunate (1.6 ± 0.2 mm versus 1.3 ± 0.3 mm) joint space thicknesses. CONCLUSIONS: There is a decreased mobility of the lunate and triquetrum bones in Madelung deformity. CLINICAL RELEVANCE: Four-dimensional imaging could be used in future studies that investigate the effect of surgical ligament release on carpal kinematics and subsequent wrist mobility.

Patient-specific plate for navigation and fixation of the distal radius: a case series.

PURPOSE: Corrective osteotomy of a malunited distal radius conventionally relies on 2D imaging techniques for alignment planning and evaluation. However, this approach results in suboptimal bone repositioning, which is associated with poor patient outcomes. In this case series, we evaluate the use of novel patient-specific plates (PSPs), which feature navigation and fixation of bone segments as preoperatively planned in 3D. METHODS: Ten participants with distal radius malunion underwent CT scans for preoperative alignment planning. Patient-specific guides and plates were designed, 3D-printed, and sterilized for use in corrective surgery of the distal radius. Pre- and postoperative results were compared in regard to clinical, functional, and radiographic outcomes. RESULTS: The application of a PSP was successful in 7 of the 10 cases. After treatment, the residual alignment error was reduced by approximately 50% compared with conventional treatment. The use of PSPs reduced pain significantly. Pre- and postoperative results were pooled and demonstrated significant correlations between: (1) pain and malpositioning, (2) the range of pro- and supination motion, the MHOQ score, the EQ-5D-5L score and dorsovolar angulation, and (3) MHOQ score and proximodistal translation. CONCLUSION: The correlation between malalignment and MHOQ score, EQ-5D-5L score, pain, and range of motion shows that alignment should be restored as well as possible. Compared to the conventional approach, which relies on 2D imaging techniques, corrective osteotomy based on 3D preoperative planning and intraoperative fixation with a PSP has been shown to improve bone alignment and reduce pain. LEVEL OF EVIDENCE: IV.

Quantitative change of perfusion in gastric tube reconstruction by sidestream dark field microscopy (SDF) after esophagectomy, a prospective in-vivo cohort study.

BACKGROUND: Anastomotic leakage is one of the most severe complications in patients undergoing esophagectomy with gastric tube reconstruction. Transection of the left gastric and gastro-epiploic artery and vein results in compromised perfusion which is seen as the major contributing factor for anastomotic dehiscence. The main objective of this prospective, observational, in-vivo pilot study is to microscopically evaluate gastric tube perfusion with Sidestream Darkfield Microscopy (SDF). METHODS: Intra-operative microscopic images of gastric-microcirculation were obtained with SDF directly after reconstruction in 22 patients. Quantitative perfusion related parameters were: velocity, Microvascular Flow Index(MFI), Total Vessel Density(TVD), Perfusion Vessel Density(PVD), Proportion of Perfused Vessels(PPV) and De Backer Score(DBS). Dedicated software was used to assess parameters predictive for compromised perfusion. RESULTS: SDF was feasible to accurately visualize and evaluate microcirculation in all patients. Velocity(µm/sec) was significantly decreased towards the fundus (p = 0.001). MFI, PVD and PVD were decreased distal of the watershed - between the right and left gastro-epiploic artery and vein - and in the fundus, compared to the base of the gastric tube(p = 0.0002). No differences in TVD and DBS were observed; because of vessel-dilation in the fundus-area. This suggests that venous congestion results in comprised inflow of oxygen rich blood and plays a role in the development of ischaemia. CONCLUSION: We present quantitative perfusion imaging with SDF of the gastric tube. Velocity, MFI, TVD and PPV are accurate parameters to observe perfusion decrease. Also, venous congestion is visible in the fundus, suggesting an important role in the development of ischaemia. These parameters could allow early risk stratification, and, potentially, can accomplish a reduction in anastomotic leakage.

Computed Tomography-Mediated Registration of Trapeziometacarpal Articular Cartilage Using Intraarticular Optical Coherence Tomography and Cryomicrotome Imaging: A Cadaver Study.

OBJECTIVE: Accurate, high-resolution imaging of articular cartilage thickness is an important clinical challenge in patients with osteoarthritis, especially in small joints. In this study, computed tomography (CT) mediated catheter-based optical coherence tomography (OCT) was utilized to create a digital reconstruction of the articular surface of the trapeziometacarpal (TMC) joint and to assess cartilage thickness in comparison to cryomicrotome data. DESIGN: Using needle-based introduction of the OCT probe, the articular surface of the TMC joint of 5 cadaver wrists was scanned in different probe positions with matching CT scans to record the intraarticular probe trajectory. Subsequently and based on the acquired CT data, 3-dimensional realignment of the OCT data to the curved intraarticular trajectory was performed for all probe positions. The scanned TMC joints were processed using a cryomicrotome imaging system. Finally, cartilage thickness measurements between OCT and cryomicrotome data were compared. RESULTS: Successful visualization of TMC articular cartilage was performed using OCT. The CT-mediated registration yielded a digital reconstruction of the articular surface on which thickness measurements could be performed. A near-perfect agreement between OCT and cryomicrotome thickness measurements was found (r2 = 0.989). CONCLUSION: The proposed approach enables 3D reconstruction of the TMC articular surface with subsequent accurate cartilage thickness measurements, encouraging the development of intraarticular cartilage OCT for future (clinical) application.

Accuracy of manual and automatic placement of an anatomical coordinate system for the full or partial radius in 3D space.

Accurate placement of a coordinate system on the radius is important to quantitatively report 3D surgical planning parameters or joint kinematics using 4D imaging techniques. In clinical practice, the scanned length of the radial shaft varies among scanning protocols and scientific studies. The error in positioning a radial coordinate system using a partially scanned radius is unknown. This study investigates whether the imaged length of the radius significantly affects the positioning of the coordinate system. For different lengths of the radius, the error of positioning a coordinate system was determined when placed automatically or manually. A total of 85 healthy radii were systematically shortened until 10% of the distal radius remained. Coordinate systems were placed automatically and manually at each shortening step. A linear mixed model was used to associate the positioning error with the length of the radial shaft. The accuracy and precision of radial coordinate system placement were compared between automatic and manual placement. For automatic placement of the radial coordinate system, an increasing positioning error was associated with an increased shortening of the radius (P = < 0.001). Automatic placement is superior to manual placement; however, if less than 20% of the radial shaft length remains, manual placement is more accurate.

Computer-Assisted Techniques in Corrective Distal Radius Osteotomy Procedures.

Malunion of the distal radius is a common complication following a distal radius fracture. The surgical treatment of a symptomatic distal radius malunion is a corrective osteotomy (CO) procedure aimed at the restoration of the anatomical alignment of the distal radius articular surface in the wrist joint. Traditional two-dimensional imaging techniques in the management of malunion have demonstrated to be limited in pre-, intra-, and postoperative imaging and visualization of the bone architecture. Over the past decades, with the advent of three-dimensional (3-D) imaging techniques, innovations have emerged in the field of preoperative planning, navigation, and 3-D printing. The aim of this paper is to review the existing literature and inform clinicians and biomedical engineers approaching the field about advantages, disadvantages, and future perspectives of existing computer-assisted technology for CO. Collected studies agree on showing the efficacy of the computed-tomography-based 3-D virtual planning. Currently, patient-specific 3-D printed guides and implants are the most promising technology to transfer the preoperative plan to the patient. However, further biomechanical studies, larger clinical trials, and a major exposure of clinicians to 3-D planning are needed to augment the feasibility of using these technologies in standard practice.

Selective denervation of the wrist for chronic pain: a systematic literature review.

Selective denervation of sensory nerve branches to the wrist is a palliative surgical treatment option for patients with chronic wrist pain when preserving the range of motion and function is preferred. Treatment varies from partial isolated denervation of the posterior interosseous nerve to extensive 'complete' denervations. This study aimed to provide an overview of the literature regarding treatment outcomes in the domains of pain, grip strength, patient satisfaction and return to work. MEDLINE (PubMed), EMBASE and Cochrane databases were systematically searched and identified 993 studies, of which 12 were eligible for analysis. Denervation resulted in high 'return to work' rates (up to 94%), patient satisfaction (up to 92%), increased grip strength (7%-64%) and improved average pain scores (36%-92%). Treatment outcomes of both partial and complete denervations were favourable; however, variations in outcomes suggest the need for improving evidence regarding surgical technique and nerve identification.

Quantitative three-dimensional assessment of Madelung deformity.

In the diagnostic work-up of Madelung deformity conventional radiographic imaging is often used, assessing the three-dimensional deformity in a two-dimensional manner. A three-dimensional approach could expand our understanding of Madelung deformity's complex wrist anatomy, while removing inter- and intra-rater differences. We measured previous two-dimensional-based and newly developed three-dimensional-based parameters in 18 patients with Madelung deformity (28 wrists) and 35 healthy participants (56 wrists). Madelung deformity wrists have increased levels of ulnar tilt, lunate subsidence, lunate fossa angle, and palmar carpal displacement. The lunate fossa is more concave and irregular, and angles between scaphoid, lunate, and triquetral bones are decreased. These findings validate the underlying principles of current two-dimensional criteria and reveal previously unknown anatomical abnormalities by utilizing novel three-dimensional parameters to quantify the radiocarpal joint.

Carpal kinematic changes after scaphoid nonunion: an in vivo study with four-dimensional CT imaging.

The aim was to evaluate if motion between the scaphoid bone fragments is related to the position of the fracture line and if a scaphoid nonunion results in the uncoupling of the proximal and distal carpal row during wrist motion. The influence of dorsal intercalated segment instability on interfragmentary motion was also analysed. In this study, 12 patients were included with unilateral scaphoid nonunion. Four-dimensional computerized tomography was used to analyse flexion-extension and radioulnar deviation motion of both wrists. We found that an increased instability of the scaphoid fragments is associated with the presence of dorsal intercalated segment instability and is not dependent on the position of the fracture line relative to the scaphoid apex. Additionally, a scaphoid nonunion results in an uncoupling of the carpal rows.

A four-dimensional-CT study of in vivo scapholunate rotation axes: possible implications for scapholunate ligament reconstruction.

Additional fixation of the palmar scapholunate interosseous ligament has been advocated to improve the long-term results of dorsal scapholunate interosseous ligament reconstruction. To investigate the validity of this approach, we determined normal scapholunate motion patterns and calculated the location of the scapholunate rotation axis. We hypothesized that the optimal location of the scapholunate interosseous ligament insertion could be determined from the scapholunate rotation axis. Four-dimensional computerized tomography was used to study the wrist motion in 21 healthy participants. During flexion-extension motions, the scaphoid rotates 38° (SD 0.6°) relative to the lunate; the rotation axis intersects the dorsal ridge of the proximal pole of the scaphoid and the dorsal ridge of the lunate. Minimal scapholunate motion is present during radioulnar deviation. Since the scapholunate rotation axis runs through the dorsal proximal pole of the scaphoid, this is probably the optimal location for attaching the scapholunate ligament during reconstructive surgery.

AMORE treatment as salvage treatment in children and young adults with relapsed head-neck rhabdomyosarcoma.

BACKGROUND AND PURPOSE: Survival after relapse of head and neck rhabdomyosarcoma (HNRMS) after prior external beam radiotherapy (EBRT) is poor, since options for adequate local treatment are often lacking. In this study we describe our experience with salvage AMORE in patients with relapsed HNRMS after prior EBRT. MATERIALS AND METHODS: Patients with relapsed HNRMS after prior EBRT in which salvage AMORE treatment was considered feasible were analysed; this includes patients with parameningeal, head and neck non-parameningeal and orbital localization. AMORE treatment consisted of Ablative surgery, MOuld technique brachytherapy and surgical REconstruction. RESULTS: In total 18 patients received salvage AMORE treatment; nine patients had relapsed parameningeal (PM) RMS, two patients had relapsed head and neck non-parameningeal RMS (HN-nonPM) and seven patients had relapsed orbital RMS. Local control rate was 67% and 5-year overall survival was 54% (95% confidence interval: 31-78%); 3/9 patients with PM RMS, 0/2 patients with HN-nonPM RMS and 6/7 patients with orbital RMS were alive after a median follow-up of 8.6 years. One patient with PM RMS survived more than 5 years after which he died from a secondary cancer. Six patients developed a local relapse (of which one patient also developed a distant metastasis) and two patients developed distant metastases. CONCLUSIONS: Salvage AMORE treatment is a feasible and effective local therapy approach even after prior EBRT. Since salvage AMORE treatment is sometimes the only curative option in patient with relapsed HNRMS, we encourage physicians to consider salvage AMORE treatment for patients with relapsed HNRMS after prior EBRT.

Surgical Management of Madelung Deformity: A Systematic Review.

Background: Madelung deformity is a congenital wrist condition characterized by volar subluxation of the wrist caused by premature growth arrest of the distal radius. Progressive symptoms can necessitate surgical intervention, yet optimal treatment strategy remains unknown. The aim of this study is to determine treatment options, surgical indications, and operative outcomes for Madelung deformity. Methods: This study adhered to the Meta-Analyses of Observational Studies in Epidemiology (MOOSE) guidelines. A comprehensive systematic review was performed to identify all studies describing surgical interventions for Madelung deformity. All studies were evaluated by level of evidence and a self-developed quality assessment tool. Results: Twenty-five studies met inclusion criteria; all case series with type IV level of evidence. Studies assessed pain, range of motion, aesthetic deformity, and grip strength. The primary indication for surgery was the presence of wrist pain. Various surgical procedures exist and could be categorized as radial lengthening, ulnar shortening, or a combination of both. All studies report postoperative pain reduction and most studies report an improved range of motion. Conclusions: A variety of surgical procedures reportedly have satisfactory outcomes. However, outcomes are reported in an inconsistent manner, prohibiting pooling of studies and comparisons of surgical procedures and their outcomes. We propose several methodological changes for implementation in future studies, increasing the quality of evidence to compensate for small patient numbers.

Psychosocial well-being of long-term survivors of pediatric head-neck rhabdomyosarcoma.

BACKGROUND: Head and neck rhabdomyosarcoma (HNRMS) survivors are at risk to develop adverse events (AEs). The impact of these AEs on psychosocial well-being is unclear. We aimed to assess psychosocial well-being of HNRMS survivors and examine whether psychosocial outcomes were associated with burden of therapy. PROCEDURE: Sixty-five HNRMS survivors (median follow-up: 11.5 years), treated in the Netherlands and the United Kingdom between 1990 and 2010 and alive ≥2 years after treatment visited the outpatient multidisciplinary follow-up clinic once, in which AEs were scored based on a predefined list according to the Common Terminology Criteria for Adverse Events. Survivors were asked to complete questionnaires on health-related quality of life (HRQoL; PedsQL and YQOL-FD), self-perception (KIDSCREEN), and satisfaction with appearances (SWA). HRQoL and self-perception scores were compared with reference values, and the correlation between physician-assessed AEs and psychosocial well-being was assessed. RESULTS: HNRMS survivors showed significantly lower scores on PedsQL school/work domain (P ≤ 0.01, P = 0.02, respectively), YQOL-FD domains negative self-image and positive consequences (P ≤ 0.01, P = 0.04, respectively) compared with norm data; scores on negative consequences domain were significantly higher (P = 0.03). Over 50% of survivors negatively rated their appearances on three or more items. Burden of AEs was not associated with generic HRQoL and self-perception scores, but was associated with disease-specific QoL (YQOL-FD). CONCLUSION: In general, HRQoL in HNRMS survivors was comparable to reference groups; however, survivors did report disease-specific consequences. We therefore recommend including specific questionnaires related to difficulties with facial appearance in a systematic monitoring program to determine the necessity for tailored care.
