Lymphaticovenous anastomosis (LVA) surgery is an effective surgery for the treatment of lymphedema in the extremities. Indocyanine green lymphography is the reference standard for visualizing lymphatics for LVA surgery, but it has several limitations; most notably, superficial dermal congestion can mask deeper lymphatic vessels. To overcome the limitations, we add contrast-enhanced ultrasound (CEUS) lymphography.

Unlabelled: The Accreditation Council for Graduate Medical Education (ACGME) implemented duty-hour restrictions limiting residents to 80 hours per week in 2003 and further extended restrictions in 2011 to improve resident and patient well-being. Numerous studies have examined the effects of these restrictions on patient outcomes with inconclusive results. Few efforts have been made to examine the impact of this reform on the safety of common plastic surgery procedures.

The novel coronavirus disease of 2019 pandemic presents a unique challenge to the field of plastic and reconstructive surgery. Although plastic surgeons may be postponing elective operations, there are still a number of emergent or urgent procedures that may need to be performed, and surgeons may be facing the reality of returning to a new normalcy of operating with coronavirus disease of 2019. These procedures, consisting of those such as head and neck reconstruction or maxillofacial trauma, largely require a multidisciplinary approach and may be considered of higher risk to health care workers because of the involvement of areas of the body identified as sources for viral transmission.

Article Synopsis
  • The study examines how non-board-certified plastic surgeons affect patient safety and their understanding of practitioners’ qualifications, focusing on city size and the influence of healthcare transparency laws.
  • Researchers conducted a Google search for "plastic surgeon" in various cities, analyzing the board certification status of the top providers found.
  • Results showed that while most practitioners were board-certified, non-certified ones were more common in smaller cities, and truth-in-advertising laws did not significantly change how practitioners market themselves.

Article Synopsis
  • The abdomen is the primary donor site for breast reconstruction, often leading to significant pain, increased opioid use, and higher hospital costs; ERAS protocols aim to improve recovery outcomes but vary widely.
  • A systematic review analyzed the effectiveness of Transversus Abdominis Plane (TAP) blocks in patients undergoing abdominally based breast reconstruction, pooling data from 12 studies with over 1100 patients.
  • Results indicated that TAP blocks significantly reduce hospital stay by about 1 day and opioid consumption by nearly 134 mg, with no significant impact on postoperative complications, hospital costs, or pain levels, suggesting they are a beneficial pain management strategy.

Persistent nasal airway obstruction (NAO) due to midvault soft tissue collapse in patients following rhinoplasty or nasal surgery is a clinical challenge for surgeons. An absorbable lateral nasal wall implant is one option available to help treat midvault soft tissue collapse and to improve NAO symptoms. Previous studies have not investigated its use in complex revision functional rhinoplasty with respect to patient-reported outcomes.

Background: Full myectomy is recommended for benign essential blepharospasm (BEB) refractory to botulinum toxin (BT) treatment, but long-term swelling, scar contracture, hollow appearance, and unnatural contour of the eyelids are common postoperative complications. We present myotomy in situ to minimize these adverse outcomes.

Methods: The redundant eyelid skin with its underlying muscle is resected first, and myotomy in situ is performed by completely cutting the residual orbicularis oculi muscles into multiple cubes and down to the subcutaneous layer, and then cutting the procerus and corrugator muscles down to the periosteum.
