Background: The anterolateral thigh (ALT) perforator flap is a workhorse flap for tongue reconstruction. The authors present an alternative option using the profunda artery perforator (PAP) flap for glossectomy reconstruction compared with the ALT flap.

Methods: A retrospective review was conducted of 65 patients who underwent subtotal or total glossectomy reconstruction between 2016 and 2020 (46 ALT versus 19 PAP flaps).

Objectives: This systematic review seeks to understand whether cold intolerance (CI) improves with time and if there is any role for management strategies such as behavioural therapy, surgery, or pharmacotherapy.

Methods: Two independent reviewers used a predefined search strategy to query MEDLINE, PubMed, Embase, CINAHL, Cochrane Library, Web of Science and Google Scholar databases. Articles written in English, Studies of interventions (such as pharmacotherapy or behavioural therapy) for cold intolerance in adult patients with a history of hand injury along with prevalence over time were included for review.

Background: Neighborhood-level factors have been shown to influence surgical outcomes through material deprivation, psychosocial mechanisms, health behaviors, and access to resources. To date, no study has examined the relationship between area-level deprivation (ADI) and post-mastectomy outcomes.

Methods: A cross-sectional survey of adult female breast cancer patients who underwent lumpectomy or mastectomy between January 2018 to June 2019 was carried out.

Background: Financial toxicity (FT) depicts the burden of cancer treatment costs and is associated with lower quality of life and survival in breast cancer patients. We examined the relationship between geospatial location, represented by rurality and Area Deprivation Index (ADI), and risk of FT.

Study Design: A single-institution, cross-sectional study was performed on adult female surgical breast cancer patients using survey data retrospectively collected between January 2018 and June 2019.

Ulnar nerve (UN) entrapment is a common peripheral neuropathy and can lead to dysfunction of both sensory and motor function of the hand. Surgical release is the mainstay of treatment, but post-operative rehabilitation of UN innervated intrinsic muscles is lacking evidence. This cohort study utilized surface electromyography (EMG) and assessed the activation of UN innervated intrinsic and extrinsic hand muscles during four exercises in healthy participants.

Background: The cost effectiveness of combining vascularized lymph node transfer (VLNT) with autologous breast reconstruction has not been established. Herein we describe the use of Markov modeling to evaluate the cost utility of VLNT with delayed autologous breast reconstruction for patients with breast cancer related lymphedema (BCRL).

Methods: We conducted a cost effectiveness analysis using a Markov model with microsimulation.

Background: Distress among newly diagnosed patients with breast cancer is common and may have an impact on their surgical decision-making. The revised Edmonton Symptom Assessment System (ESAS-r) is a validated instrument that provides an estimate of patients' total distress, and no previous study has related preoperative scores to the choice to have breast reconstruction.

Methods: Women with breast cancer treated at the Princess Margaret Cancer Centre in 2014 were reviewed, and patient and tumor characteristics were collected from local databases.

Article Synopsis
  • Large chest wall resections can lead to significant respiratory issues and complications, often resulting in prolonged ventilator use.
  • A study of 59 patients found that those undergoing resections from the superior/middle regions faced higher rates of complications (71.4% vs. 35.3%) and an 8.5% mortality rate within 90 days post-surgery.
  • Factors like preoperative chemotherapy and radiation therapy were linked to shorter survival times, highlighting the complexity of managing large oncological chest wall defects and their reconstruction challenges.

Purpose: An understanding of patient expectations predicts better health outcomes following breast reconstruction. No study to date has examined how patient expectations for breast reconstruction and preoperative health-related quality of life vary with time since breast cancer diagnosis.

Methods: Women consulting for breast reconstruction to a single surgeon's practice over a 13-month period were enrolled in this cross-sectional study.

Background: Meta-analyses are common in the plastic surgery literature, but studies concerning their quality are lacking. The authors assessed the overall quality of meta-analyses in plastic surgery, and attempted to identify variables associated with scientific quality.

Methods: A systematic review of meta-analyses published in seven plastic surgery journals between 2007 and 2017 was undertaken.

Background: Unilateral coronal craniosynostosis is a challenging condition in craniofacial surgery. Frontoorbital advancement by single-stage resorbable remodeling and distraction osteogenesis (DO) techniques have known intraoperative differences, but their comparative outcomes are less well characterized.

Methods: A systematic literature search of the MEDLINE, EMBASE, LILACS, and Web of Science databases was conducted.

Purpose: Surgeons and resident physicians in a clinic setting often visually estimate Dupuytren flexion contractures of the hand to follow disease progression and decide on management. No previous study has compared visual estimates with a standardized instrument to ensure measurement reliability.

Methods: Consecutive patients consulted for Dupuytren flexion contractures of the hand had individual joint contractures estimated in degrees (°) by both a resident physician and staff surgeon.

Health literacy is the extent to which patients are able to understand and act upon health information. This concept is important for surgeons as their patients have to comprehend the nature, risks and benefits of surgical procedures, adhere to perioperative instructions, and make complex care decisions about interventions. Our review aimed to determine the prevalence of limited health literacy of the surgical patient population.

Background: Our aim was to determine whether the thoracodorsal (Td) vessels have comparable clinical outcomes to the internal mammary (IM) vessels as recipients for autologous free tissue transfer for breast reconstruction.

Methods: Systematic searches of MEDLINE, EMBASE, CENTRAL, and World of Science from inception to June 2016 were performed by two independent reviewers. Studies that included adult females undergoing autologous free tissue transfer for breast reconstruction were selected.
