AI Article Synopsis
- The study aimed to evaluate the impact of using one versus two veins for outflow in microvascular free tissue transfers for head and neck reconstruction.
- A retrospective review of cases from January 2004 to December 2012 included 309 patients, revealing that the majority (67.2%) utilized single vein anastomosis.
- Results indicated that single vein usage was linked to a higher rate of venous congestion, with 81.1% of affected cases using one vein, highlighting that two vein connections helped reduce complications.
Article Abstract
Background: The purpose of this study was to determine the benefit of 1-vein versus 2-vein outflow in microvascular free tissue transfers.
Methods: A retrospective review reflects the experience of 6 surgeons. Analysis included all patients who underwent reconstruction at a single institution between January 2004 and December 2012.
Results: Three hundred nine patients underwent a total of 317 microvascular free flap reconstructions for head and neck defects. Two hundred thirteen of 317 flaps (67.2%) used 1 venous anastomosis and 104 (32.8%) used 2 venous anastomoses. Venous congestion necessitated urgent take back in 37 of 57 patients (64.9%) requiring exploration for perioperative complications. Thirty of 37 flaps (81.1%) with venous congestion had 1 vein anastomosis, whereas 7 (18.9%) had dual vein outflow (p = .03). Overall flap success was 303 of 317 (95.6%), despite an 18.0% (57 of 317) perioperative take back rate.
Conclusion: Coapting 2 veins was shown to minimize venous congestion. © 2015 Wiley Periodicals, Inc. Head Neck 38: 820-823, 2016.

Objective: In this study, the research team aimed to explore the therapeutic effectiveness of hyperbaric oxygen therapy (HBOT) for noise-induced hearing loss (NIHL), its influence on patient prognosis, and its impact on hearing to provide valuable clinical evidence.
Methods: Ninety-four patients with NIHL admitted to The First People's Hospital of Changde City, Hunan, China, from May 2021 to January 2023 were selected for this retrospective analysis. Among them, 43 were given conventional treatment (control group) and 51 were given HBOT (observation group).

Lipomas are benign soft tissue tumors composed of mature adipocytes, commonly found in subcutaneous tissues. Despite their prevalence in various body regions, they are relatively rare in the oral and maxillofacial regions. This study retrospectively analyzed the clinical and imaging characteristics, as well as the treatment outcomes of 57 patients diagnosed with lipoma.

Department of Plastic and Reconstructive Surgery, Saitama Medical University International Medical Center.
This study aimed to develop a novel reconstruction method for segmental mandibulectomy. In the authors' opinion, reconstruction of the anterior border of the mandibular ramus using a double-arm vascularized fibular flap is important to prevent deformity due to buccal depression and the accumulation of food debris, thereby eliminating masticatory dead space that cannot be filled with prostheses such as implants or dentures. Using conventional reconstruction plates, the reconstructed bone positioned at the anterior border of the mandibular ramus required either fixing with only 1 screw or using 2 plates for stable fixation, making it difficult to position the plates stably.

Objective: The impact of suture materials on surgical site infections (SSIs) has been well documented in various surgical fields; however, it has not been thoroughly examined in oral oncological surgery with free-flap reconstruction. This study aimed to evaluate the incidence of oral SSIs associated with the use of monofilament and braided sutures for flap fixation.
Methods: A retrospective chart review of patients who underwent oral oncological resection with free-flap reconstruction was conducted between May 2020 and April 2024.

Montelukast, a leukotriene receptor antagonist (LTRA) approved for the treatment of asthma and allergic rhinitis, is widely used, though real-world data on its application in asthma management remain limited. This registry-based study evaluated the use of montelukast in adult asthma patients, examining demographic and disease characteristics, asthma control status, asthma phenotypes, presence of atopy, and treatment regimens. Among 2053 patients analyzed, 61.
