Patient and observer scar assessment scores favour the late appearance of a transverse cervical incision over a vertical incision in patients undergoing carotid endarterectomy for stroke risk reduction

Neck scar perception after neck dissection in HPV-associated oropharyngeal squamous cell carcinoma

IMPORTANCE

While there has been an increased understanding of the impact of visible neck scars in some patients with certain diseases, this has not yet been explored in the HPV+ OPSCC population.

OBJECTIVE

To understand patients' perception of their scar and the impact on their quality of life (QOL) at least 6 months after neck dissection (ND) for HPV+ oropharyngeal squamous cell carcinoma (OPSCC).

DESIGN, SETTING, AND PARTICIPANTS

In this retrospective case-control study, patients who underwent primary transoral robotic surgery (TORS) and ND for HPV+ OPSCC between 2016 and 2021 at a single tertiary care center were identified. Data analysis was performed in January 2022.

MAIN OUTCOMES AND MEASURES

Dermatology Life Quality Index was modified (mDLQI) to assess patients' perceptions of their scars. The primary outcome was the mean mDLQI survey score with higher scores corresponding to worse perceptions. Three questions adapted from the Self-Consciousness Scale (SCS) were also included to assess awareness of appearance. All questions were scaled on a 0-3 Likert Scale. Tweedie generalized linear model was used to understand the relationship between mDLQI score and patient- and procedure-specific factors (including the three SCS survey questions). An additional exploratory logistic regression was performed to understand the risk factors for clinically significant mDLQI score change.

RESULTS

A total of 67 patients (response rate 57 %) completed the survey with a mean mDLQI survey score of 0.84 (max 30). Although there was a statistically significant negative association between private insurance and mDLQI survey score (95 % Confidence Interval [CI]: -2.72 - -0.38), and a positive association between the SCS score and mDLQI survey score (95 % CI: 0.23-0.81) (p < 0.05), these variables were not found to be risk factors for a clinically significant difference in mDLQI on multivariable analysis.

CONCLUSION

The majority of patients felt their neck scars did not interfere with their daily lives. Patient perceptions of neck scars were consistent despite differing patient characteristics and treatment regimens.

[Evolution of surgical approaches to carotid bifurcation]

Carotid endarterectomy is preferable for prevention of acute cerebrovascular accident associated with atherosclerotic lesions of internal carotid artery. Modern interest in minimizing local complications and small excisions is also actual in carotid surgery. The authors review the modern literature data on evolution of carotid arteries exposure. Cutaneous mini-incision, transverse skin incision and retrojugular approach are discussed. The authors consider the advantages and possible complications of each technique.

Patient Perceptions of Paramedian Minimally Invasive Spine Skin Incisions

BACKGROUND

In clinical outcome studies, patient input into the factors that drive higher satisfaction with lumbar minimally invasive spinal surgery (MISS) is rare. The skin incision is often the only visible consequence of surgery that patients can assess. The authors were interested in patients' opinions about the type of lumbar paramedian minimally invasive spinal (MIS) skin incision employed during MISS and how novel skin incisions could impact patients' interpretation of the outcome. The authors wanted to compare traditional lumbar stab incisions to three novel lumbar paramedian (MIS) skin incisions to determine if further study is indicated. The primary objective was to examine patient satisfaction and perceptions regarding lumbar paramedian MIS skin incisions.

METHODS

We reviewed the literature and conducted a patient opinion survey. Responses were solicited from back pain patients from a single chiropractic office. Survey questions regarding novel skin incisions for minimally invasive spine surgery (NSIMISS) were conceptualized. The three novel skin incisions were designed using Langer's lines to reduce the total number of incisions; improve patient satisfaction; increase ease of surgical approach/fixation; and reduce operative time/radiation exposure.

RESULTS

One hundred and six participants were surveyed. When shown traditional lumbar paramedian MIS skin stab incisions, 76% of respondents indicated negative responses, n = 65. The majority of patients chose traditional stab incisions (n = 41) followed by novel larger intersecting incisions (n = 37). The least popular incisions were the novel horizontal (n = 20) and the novel mini oblique (n = 5) incisions. Female patients worried more than male patients about how their incision looked. However, there was no statistically significant difference (p value of 0.0418 via Mann-Whitney U one-tailed test and p value of 0.0836 via Mann-Whitney U two-tailed test). Patients less than or equal to 50 years of age worried more than patients over 51 years of age, which was statistically significant (p value of 0.0104 via Mann-Whitney U one-tailed test and p value of 0.0208 via Mann-Whitney U two-tailed test).

CONCLUSIONS

Patients do have opinions on the type of lumbar paramedian MIS skin incision used. It appears that younger patients and female patients worry most about how the incision on their back looks after surgery. A larger population of patients across many demographics is needed to validate these findings.

A clinical comparison of pure knitted silk and a complex synthetic skin substitute for the treatment of partial thickness burns

Currently, many dressings are commercially available for the treatment of burn wounds. Some of these wound dressings remain on the wound, prevent painful dressing changes, and reduce tissue scarring. Nevertheless, still a wound dressing that is cost-effective, produces good wound healing properties, and has a high patient satisfaction is needed. Standard care of superficial burn wounds differs between burn centres. This study aimed to determine a dressing with easy appliance, accurate pain control, favourable outcome, and cost-effectiveness. Therefore, we compared the widely used but expensive Suprathel with the rather new but much cheaper Dressilk in the clinical setting. In a prospective clinical study, the healing of partial thickness burn wounds after simultaneous treatment with Suprathel and Dressilk was examined in 20 patients intra-individually. During wound healing, pain, infection, exudation, and bleeding were evaluated. A subjective scar evaluation was performed using the Patient and Observer Scar Scale. Both dressings were easy to apply, remained on the wound in place, and were gradually cut back as reepithelisation proceeded and showed similar times to wound closure. Dressing changes were not necessary, and neither infections nor bleeding was detected. Overall exudation and pain were highest in the beginning but declined during the wound-healing phase without significant differences. In the follow-up scar evaluation after 12 months, patients reported overall high satisfaction. Overall, the modern dressings Suprathel and Dressilk (solely made out of pure silk) led to safe wound healing without infection and rapidly reduced pain. There was no need for dressing changes, and they had similar clinical outcomes in scar evaluation. Therefore, both dressings seem to be ideal for the treatment of superficial burns. Because acquisition costs remain one of the main factors in the treatment of burns, Dressilk, which is ~20 times cheaper than Suprathel, remains a good option for the treatment of partial thickness burns.

[Minimally invasive carotid artery surgery]

OBJECTIVE

To determine the criteria for choosing a surgical approach and compare an effectiveness of carotid endarterectomy (CEAE) via 3 approaches.

MATERIAL AND METHODS

The study included 120 patients who underwent CEAE via 3 different approaches. Intraoperative skin marking included lower jaw angle, skin fold closest to common carotid artery bifurcation. Carotid artery bifurcation and borders of atherosclerotic plaque were visualized using ultrasound. An effectiveness of each access was evaluated in accordance with the following criteria: neurological complications, cosmetic effect and quality of life after 1 and 12 months. The patients were divided into 2 groups. Group I - 80 patients with CEAE with access through the natural skin fold (NSF); group II - 40 patients with CEAE using the classical longitudinal access. The 1st group was divided into 2 subgroups. Subgroup I A - 39 patients with CEAE using mini-access via NSF; subgroup I B - 41 patients with CEAE using extended access via NSF.

RESULTS

There were no strokes and transient ischemic attacks in a month after surgery in both groups. After 12 months, stroke occurred in 2 (%) patients of group II, cranial neuropathy - 8 (21%) patients in the same group. The best cosmic effect was achieved in subgroup I A after 1 and 12 months (37.1±6.7 scores). Mean score of physical health was 51.59±5.9 scores in subgroup I A, 46.03±7.53 scores - in subgroup I B, 38.84±5.28 scores - in group II. Index of mental health was 49.63±6.69, 45.68±5.6, and 48.59±7.29 scores, respectively.

CONCLUSION

Considering these data, we developed a personalized computer program ensuring fast choice of optimal surgical approach.

Surgical Technique for Carotid Endarterectomy: Current Methods and Problems

Over the last 60 years, many reports have investigated carotid endarterectomy (CEA) and techniques have thus changed and improved. In this paper, we review the recent literature regarding operational maneuvers for CEA and discuss future problems for CEA. Longitudinal skin incision is common, but the transverse incision has been reported to offer minimal invasiveness and better cosmetic effects for CEA. Most surgeons currently use microscopy for dissection of the artery and plaque. Although no monitoring technique during CEA has been proven superior, multiple monitors offer better sensitivity for predicting postoperative neurological deficit. To date, data are lacking regarding whether routine shunt or selective shunt is better. Individual surgeons thus need to select the method with which they are more comfortable. Many surgical techniques have been reported to obtain distal control of the internal carotid artery in patients with high cervical carotid bifurcation or high plaque, and minimally invasive techniques should be considered. Multiple studies have shown that patch angioplasty reduces the risks of stroke and restenosis compared with primary closure, but few surgeons in Japan have been performing patch angioplasty. Most surgeons thus experience only a small volume of CEAs in Japan, so training programs and development of in vivo training models are important.

An Alternative Approach to Carotid Endarterectomy in the High Carotid Bifurcation

BACKGROUND

Surgical exposure of a high carotid bifurcation (HCB) for carotid endarterectomy (CEA) can be technically challenging due to the presence of bony structures in the most cranial portion of the neck and is associated with significant morbidity making carotid artery stenting (CAS) a common alternative. However, a high transverse neck incision with subplatysmal flaps facilitates CEA in these patients without additional exposure techniques. We present a high transverse neck incision with subplatysmal flaps as an alternative to the standard surgical exposure of the carotid bifurcation to facilitate CEA in patients with HCB.

METHODS

Four patients with carotid bifurcations located cranial to the C3-4 vertebral interspace (identified on preoperative imaging) requiring intervention underwent CEA using a high transverse neck incision through an existing skin crease with subplatysmal flap elevation. CEA was performed in a standard fashion with bovine pericardial patch.

RESULTS

Two male and 2 female patients with an average age of 65 years successfully underwent CEA using this incision. One patient underwent concurrent carotid body tumor excision. None of the patients required mandibulotomy or hyoid bone resection. Two patients required division of the posterior belly of the digastric muscle. There were no perioperative complications. Primary patency was 100% in the 4 patients with surveillance studies, and mean follow-up of 160 days (range 54-369 days). There were no significant cranial nerve injuries. No patient required conversion to an endovascular procedure due to inaccessibility of the lesion or subsequent interventions for incomplete endarterectomy.

CONCLUSIONS

A high transverse incision with subplatysmal flaps is a safe, effective, and cosmetically preferable surgical approach in patients with HCB requiring carotid artery intervention and may be an alternative to CAS.

[Advantages of minimally invasive approach for carotid endarterectomy]

OBJECTIVE

To identify the advantages and disadvantages of different approaches for carotid endarterectomy (conventional, longitudinal and transverse incision).

MATERIAL AND METHODS

There were 58 patients who underwent carotid endarterectomy. Patients were divided into 2 groups depending on surgical approach. Group 1 (n=37) - minimal skin incision (less than 5 cm). There were subgroup 1A (transverse minimal skin incision along the natural skin wrinkle, n=17) and subgroup 1B (longitudinal minimal skin incision, n=20). Group 2 (n=21) - conventional longitudinal incision. Surgical outcomes were analyzed after 1 month and 1 year. End-points were mortality, stroke, TIA, cranial nerve neuropathy. Cosmetic effect was evaluated using POSAS scale (Patient and Observer Scar Assessment Scale, Draaijers, 2004).

RESULTS

Mortality, stroke and TIA were absent after 1 month. Cranial nerve neuropathy was not observed in subgroup 1A and diagnosed in 2 (10%) patients of subgroup 1B and 6 (28.5%) patients of group 2. Cosmetic effect: subgroup 1A - 48.4±9.5 scores, subgroup 1B - 52.4±9.2, group 2 - 63.1±11.1 (p<0.05). The outcomes after 12 months: mortality was absent in subgroups 1A and 1B, 2 patients died in group 2 from AMI. Stroke was absent in subgroups 1A and 1B, group 2 - 1 patient. Cranial nerve neuropathy was absent in 1A and 1B subgroups and diagnosed in 4 (21%) patients of group 2. Cosmetic effect: subgroup 1A - 37.2 scores, subgroup 1B - 40.0 scores, group 2 - 55.1 scores. Physical component of QOL: subgroup 1A - 51.63±6.31 scores, subgroup 1B - 46.01±7.53 scores, group 2 - 38.85±5.33 scores. Psychological component of QOL: subgroup 1A - 49.64±6.72 scores, subgroup 1B - 45.68±5.63 scores, group 2 - 48.6±7.36 scores (p<0.05).

CONCLUSION

Transverse minimal skin incision for carotid endarterectomy is a safe alternative to classic longitudinal incision and reduces the risk of postoperative complications with significant cosmetic effect.

Outcomes after Transverse-Incision 'Mini' Carotid Endarterectomy and Patch-Plasty

Purpose

Traditional exposure for carotid endarterectomy (CEA) involves making a longitudinal incision parallel to the anterior border of the sternocleidomastoid. Such incisions can be painful, aesthetically displeasing, and associated with a high incidence of cranial nerve injury (CNI). This study describes the outcomes of CEA performed through small (<5 cm long), transversely oriented incisions located directly over the carotid bifurcation, as identified by color-enhanced Duplex ultrasound.

Materials and Methods

Patient demographics and operative data were collected retrospectively from an in-house database of consecutive vascular patients undergoing CEA with a small transversely oriented incision for both symptomatic and asymptomatic carotid artery stenoses.

Results

A total of 52 consecutive patients underwent CEA between 2012 and 2016 (median age, 73.5 years; interquartile range, 67–80.3; male/female ratio, 40:12). CEA was performed under regional/local anesthesia (LA) in 48 (92.3%) patients, with 4 (7.7%) being performed under general anesthesia. One patient under LA experienced neurological dysfunction intraoperatively (manifesting as an inability to count out loud) that resolved with insertion of shunt. One patient experienced a transient neurological event (expressive dysphasia) within the immediate postoperative period, which resolved within 6 hours. No in-hospital death or perioperative major adverse cardiovascular events were noted. No persistent CNIs nor bleeding complications necessitating re-exploration were reported. Follow-up data were available for a median period of 3.1 years and for all patients. Three patients experienced strokes following discharge (2 strokes contralateral to and 1 transient ischemic attack ipsilateral to the operated side).

Conclusion

Small, transversely orientated incisions, hidden within a neck skin crease can be safely performed in the majority of patients undergoing CEA.

Patient and Physician Assessment of Surgical Scars: A Systematic Review

Importance

Surgical scarring affects patients by distracting the gaze of onlookers, disrupting social interactions, and impairing psychosocial health. Patient and physician agreement regarding ideal scar characteristics is important in developing congruent expectations after surgery.

Objective

To summarize published studies assessing patient and physician ratings of surgical scars, rates of patient and physician agreement in scar assessment, and elements of cutaneous scar assessment that differ between patients and physicians.

Evidence Review

A literature search of Ovid/Medline, PubMed, and EMBASE was conducted from January 1, 1972, to August 1, 2015. Prospective studies comparing scars from different surgical techniques using at least 1 physician-reported and patient-reported scar measure were included. Strength of studies was graded according to the Oxford Centre for Evidence-Based Medicine guidelines.

Findings

The review identified 29 studies comprising 4485 patients. Of the 29 included studies, 20 (69%) were randomized clinical trials (RCTs), 5 (17%) were prospective, nonrandomized studies, and 4 (14%) were descriptive studies. Disagreement between patients and physician evaluation of scars occurred in 28% (8 of 29) studies, with only patients rating scar difference in 75% (6 of 8) of these cases. Patients were more likely to value scar depth while physicians were more likely to value scar pigmentation and relief.

Conclusions and Relevance

Methodologically rigorous studies that include clinician- and patient-reported scar outcomes are uncommon. Studies that incorporate subjective and objective scar grading reveal disagreement between patients and clinicians. Of the incision and wound closure techniques assessed, few affected patient- and clinician-reported outcomes, but the evidence remains weak and future studies are recommended.

Outcome of Beveled versus Vertical IncisionTechnique after Reconstructive or Aesthetic Facial Surgery

Background:

We suggest that the degree of scar improvement with a beveled incision technique with an angle of about 20 degrees to the skin can be translated for various reconstructions on the face and can be verified by a validated clinical assessment scale and histology.

Methods:

A total of 5 patients (2 men and 3 women) with a mean age of 68 years (range 54–84 years) undergoing elective surgeries on the face for tumor excision or cosmetic procedures were included. The beveled incision technique was compared with the conventional vertical incision (control group). Outcome measures were major and minor complications, pain and scar quality using the Patient and Observer Scar Assessment Scale, and histomorphologic scar assessment.

Results:

After a mean follow-up of 7.6 months (range 6–13 months), all patients healed uneventfully without pain, hypertrophic scars, or infection. We found a better overall Patient and Observer Scar Assessment Scale score in the beveled incision technique group (15 ± 3.4) compared with the conventional vertical incision group (18.4 ± 7.8, P = 0.7). Histomorphologic analyses showed after 6 months less scar zone, less inflammatory reaction, fewer macrophages, less foreign body reaction, and more hair follicles in the beveled incision technique group compared with the vertical incision group.

Conclusion:

We showed that the beveled incision technique using a 20-degree angle in elective surgeries on the face yields a cosmetic pleasant result for both the patient and the surgeon, which also goes in line with our histomorphologic analyses.

Cosmetic effects of skin-crease camouflage incision versus longitudinal incision following carotid endarterectomy

Introduction

Despite the increasing use of carotid angioplasty and stenting (CAS), carotid endarterectomy (CEA) nonetheless remains a more medically beneficial method of treatment for carotid artery stenosis. Therefore, one possibility for progress within this procedure may be to use minimally invasive carotid surgery, especially when the scar is in plain sight: the use of the natural wrinkles (skin crease) as a camouflage of the skin incision provides significant cosmetic improvements.

Aim

To compare the cosmetic effects of classic and trans-wrinkle CEA. To assess the distance between the carotid artery bifurcation (CAB) and the skin-crease incision whilst attempting CEA.

Material and methods

It was a randomized prospective study with two groups: patients undergoing classic surgery (control group; n = 100) and skin-crease trans-wrinkle camouflaged CEA (study group; n = 100). Follow-up was at 2 months and 1 year.

Results

The medical results of the treatment were similar in both groups. The cumulative count of strokes and myocardial infarctions was 0.5% within 30 days, and after one year 3.5% (and 5.5% including cases of death). The superiority of the transverse crease being hidden compared to the conventional longitudinal technique was proven in the Patient and Observer Scar Assessment Scale (POSAS) score, respectively 11.4 ±1.0 vs. 14.1 ±3.4 (p = 0.0001) after 2 months and 13.5 ±2.8 vs. 14.1 ±3.4 (p = 0.039) after a year.

Conclusions

Trans-wrinkle incision gives better cosmetic results, can be safely performed in most cases, and offers a comfortable approach during CEA.

Outcomes of Surgical Excision and Brachytherapy in Intractable Keloids

BACKGROUND

Keloids as unusual scars are injury remnants characterized by bizarre cosmetics and painful itching. This study assessed outcomes of surgical excision and brachytherapy in intractable keloids.

METHODS

Six patients with 10 keloid lesions were followed up. Surgical excision was done with 1-2 mm margin, and then radiotherapy was undertaken in 3 divided fractions on days 0, 1 and 2 after surgery. Scar improvement was evaluated by patients and observer with scar assessment scale (POSAS).

RESULTS

Median age of patients was 38.3±6.4, while 40% were male and 60% were female. The mean primary size of the lesion before brachytherapy was 325.18±426.16 mm² and the median size was 153.48 mm². The mean primary size of the lesions with recurrence before brachytherapy was 150.50±124.78 mm². The clinical improvement of the scars with POSAS scoring by the observer was 17.1±3.2 and by the patients was 20.8±11.5. In 5 patients who were evaluated, two keloid lesions showed recurrence (20%), and 8 lesions had no recurrence (80%). No patients reported side effects, but only one patient, a 43 years old woman with 5 keloid lesions, suffered wound infection and local dehiscence of the wound, followed by the second session of brachytherapy. The average time of relapse was 26.3±0.9 months.

CONCLUSION

The use of surgical resection in combination with brachytherapy was demonstrated as a modality for treatment of refractory keloid scars that can be recommended to surgeons who deal with these patients.
