Aesthetic outcomes after surgical repair of pectus excavatum in females: Differences between patients and professional evaluators

A qualitative study of mammography best practice positioning for female body habitus and breast tissue inclusion in Australia

INTRODUCTION

Optimal positioning in mammography is key to maximise the inclusion of breast tissue on the image. This study aimed to explore the top performing Australian radiographers' mammography best positioning techniques for patients with various body habitus and their perspective on optimised breast tissue inclusion.

METHODS

Twelve qualified Australian female radiographers with an age range of 20-70 years with equal representation from screening and diagnostic mammography settings were invited through Volpara® Health to participate in an online individual semi structured interview. Audio-recorded data was transcribed and analysed thematically. Key demographics of the participants include age, education, and mammographic experience.

RESULTS

Three key themes emerged for the craniocaudal (CC) view and the mediolateral oblique (MLO) view: good communication, CC detector height and MLO image receptor (IR) angle. Responses to each theme were categorised under six female body habitus for both the CC and MLO views: small, average, large, rib hump, pectus excavatum and pectus carinatum. Effective communication was demonstrated as critical by radiographers during positioning for varied body habitus. A 45° angle was commonly used for an average, small and large body habitus.

CONCLUSION

Appropriate and customised positioning and effective communication is important during mammography positioning to maximise breast tissue inclusion on the image. Routine CC and MLO positioning techniques cannot be applied for patients with extreme curvature of the thorax or protruding sternum and ribs.

IMPLICATIONS FOR PRACTICE

It is critical for mammography screening programs to include a language interpretation service that targets patients from multiple cultural backgrounds to enhance effective communication during positioning. This study highlights best positioning technique by radiographers that may impact women with extreme thorax curvature or protruding ribs, and subsequent obstruction in optimal positioning.

Australian radiographers' digital era practice in selecting the image receptor angle for female body habitus for the mediolateral oblique view of the breast

INTRODUCTION

Correct alignment of the image receptor (IR) in mammography for the mediolateral oblique (MLO) view of the breast is fundamental to enable the maximum inclusion of breast tissue. This study aims to assess Australian radiographers' knowledge and digital era practice in selecting the IR angle for female body habitus in the MLO view of the breast.

METHODS

An online survey was distributed to all members of the Australian Society of Medical Imaging and Radiation Therapy (ASMIRT) through their electronic newsletter and via direct email to radiographers holding the Certificate of Mammographic Practice (CMP). Descriptive analysis was undertaken, and a Pearson's chi-squared test of independence was used to compare associations between academic qualification and IR selection data. A value of p < 0.05 was deemed statistically significant.

RESULTS

A total of 107 valid surveys were returned; 67.3 % reported using the posterior lateral margin to select the IR angle. For linear body habitus, 44.9 % reported using 50°; for all other body habitus, participants most commonly used 45° (59.1 %); 85.1 % used a range of angles between 40 and 55°; 16.8 % recognised the link between correct IR angle selection and breast tissue inclusion.

CONCLUSION

The range of angles used in practice has reduced in the digital era; the frequency of the use of 45° across all body habitus may reflect tube angle movement automation. Few radiographers recognised the important link between correct selection of IR angle and breast tissue inclusion on the image.

IMPLICATIONS FOR PRACTICE

Understanding of the link between IR angle selection and image quality enhances current practice in the digital era to maximise the inclusion of breast tissue and minimise the potential of missed breast cancer.

Systematic review of physiological and psychological outcomes of surgery for pectus excavatum supporting commissioning of service in the UK

BACKGROUND

Pectus excavatum (PEx) is the most common congenital chest wall abnormality affecting 1 in 400 births in the UK. PEx is associated with significant physiological and psychological impairment. While readily surgically correctable, the benefits that surgery can bring have been debated and proven difficult to objectively measure. In the UK, this has led to the decommissioning of PEx surgery. The aim of this review is to conduct a systematic search of the literature on PEx surgery to assess physiological and psychological outcomes.

METHODS

A systematic review of the MEDLINE (PubMed), Embase and Cochrane databases was performed. Articles were sought which included patients undergoing surgery for PEx and reported on changes in cardiopulmonary measures, symptoms, quality of life and psychological assessments before and after surgical repair. Last search was performed in July 2022 and relevant findings were synthesised by narrative review.

RESULTS

Fifty-one articles were included in qualitative synthesis, with 34 studies relating to physiological outcomes and 17 studies relating to psychological and quality of life measures. Twenty-one studies investigated pulmonary function at rest. There was no change in forced vital capacity or forced expiratory volume in 1 second following open repair and transient reductions followed closed repair. In the 11 studies investigating echocardiography, transthoracic rarely demonstrated cardiac compression; however, transoesophageal demonstrated intraoperative relief in cardiac compression in severe cases. Sixteen studies investigated exercise testing (cardiopulmonary exercise testing, CPET), 12 of which demonstrated significant improvement following surgery, both in maximal oxygen consumption and oxygen pulse. Seventeen studies investigated quality of life, all but one of which showed improvement following repair of PEx. All papers that reported on patient satisfaction following surgery found high rates, between 80% and 97%.

DISCUSSION

While the majority of studies to date have been small and data heterogeneous, the literature shows that for many patients with PEx, there exists a cardiopulmonary limitation that while difficult to objectify, is likely to improve with surgical repair. Resting parameters offer little yield in aiding this except in the most severe cases. CPET therefore offers a better option for dynamic assessment of this limitation and improvements following repair. Surgery significantly improves psychological well-being and quality of life for patients with PEx.

Optimizing aesthetic results in autologous breast reconstruction

Advances in breast cancer management have provided most patients with the hope for cure or avoidance of cancer altogether. Such advances have made quality of life much more important after treatment and have led to equally incredible advances in breast reconstruction, to the point where reconstructive goals have altered the way mastectomies are now performed. As experience and expertise in microsurgery has grown, the surgical feat of successfully transferring tissue to restore breast volume is no longer considered an adequate endpoint for aesthetic breast reconstruction. A shift towards patient-centered care has motivated plastic surgeons to adapt their approaches to reconstruction integrating aesthetic principles to the process of recreating a breast mound in order to provide patients with a long-term, natural, and optimal result. Vital to restoring a shapely breast is a thorough preoperative assessment and the understanding of the breast footprint, breast conus, skin envelope and nipple-areolar complex (NAC) position. These aesthetic goals should also extend to the donor site, where adequate contour improvement is sought to offset the price of the donor site scar and the morbidity is minimized. By utilizing strategies for optimizing the NAC position, incorporating novel techniques to ensure core projection, and paying attention to the donor site, the skilled microsurgeon can elevate breast reconstruction to the level of true aesthetic surgery where the reconstructed appearance is superior to the presurgical one.

Evaluating Cardiac Lateralization by MRI to Simplify Estimation of Cardiopulmonary Impairment in Pectus Excavatum

BACKGROUND

The severity of pectus excavatum is classified by the Haller Index (HI) and/or Correction Index (CI). These indices measure only the depth of the defect and, therefore, impede a precise estimation of the actual cardiopulmonary impairment. We aimed to evaluate the MRI-derived cardiac lateralization to improve the estimation of cardiopulmonary impairment in Pectus excavatum in connection with the Haller and Correction Indices.

METHODS

This retrospective cohort study included a total of 113 patients (mean age = 19.03 ± 7.8) with pectus excavatum, whose diagnosis was verified on cross-sectional MRI images using the HI and CI. For the development of an improved HI and CI index, the patients underwent cardiopulmonary exercise testing to assess the influence of the right ventricle's position on cardiopulmonary impairment. The indexed lateral position of the pulmonary valve was utilized as a surrogate parameter for right ventricle localization.

RESULTS

In patients with PE, the heart's lateralization significantly correlated with the severity of pectus excavatum (p ≤ 0.001). When modifying HI and CI for the individual's pulmonary valve position, those indices are present with greater sensitivity and specificity regarding the maximum oxygen-pulse as a pathophysiological correlate of reduced cardiac function (χ² 10.986 and 15.862, respectively).

CONCLUSION

The indexed lateral deviation of the pulmonary valve seems to be a valuable cofactor for HI and CI, allowing for an improved description of cardiopulmonary impairment in PE patients.

[Congenital thoracic deformities and 3D custom-made implants. New classification based on a series of 789 treated cases]

The authors present a new study on 789 cases of congenital thoracic malformations including 638 pectus excavatum and 151 Poland syndromes, according to a new classification which completes Chin's one. All these malformations were treated with silicone elastomer implants. The contribution of computer-aided design and manufacturing (CAD/CAM) since 2008 is essential. The one-stage surgical protocol is precisely described. The results are impressive, permanent, for life, and complications are rare. The authors evoke a common vascular etiopathogenesis theory at the embryonic stage and question the heavy techniques of invasive remodeling that are most often unjustified.

Correction of temporal hollowing after pterional craniotomy by autologous fat grafting. A single-center experience

OBJECTIVE

Aesthetic complications following neurosurgical procedures impact patient quality of life and self-perception. Postoperative temporal hollowing is frequently seen after temporal craniotomy, resulting mainly from atrophy of the temporal muscle. Autologous fat grafting is a tailorable method to correct such approach-related sequelae. We herein present our clinical patient series and discuss pearls and pitfalls of this method.

METHODS

In this retrospective single-center study, correction of postoperative temporal hollowing using autologous fat grafting was performed in 16 patients. Temporal tissue thickness ratio was measured using magnetic resonance tomography images to visualize the graft. Patients, plastic surgeons and neurosurgeons evaluated the results independently using the herein presented scale.

RESULTS

The mean interval between the neurosurgical procedure and fat grafting was 62 months. A mean volume of 11.5 ml autologous fat was injected in an average of 2.5 sessions after initial rigotomy. Temporal tissue thickness was significantly augmented at a mean of 2.2 years after the operation (mean 0.71 ± 0.25, range 0.43-1.1; p=0.0214) as compared to the preoperative finding (mean 0.48 ± 0.1, range 0.32-0.6). Patients were more satisfied with the results than were surgeons, reflecting the significant impact of the deformity on patient self-esteem.

CONCLUSIONS

Autologous fat grafting is a valuable method for correcting postoperative temporal hollowing that provides stable results, high patient and surgeon satisfaction and can be tailored to the patient's individual needs. It should not be considered a merely aesthetic operation, but an important rehabilitation step towards restoring the patient's quality of life.
