A new therapeutic approach in Gorham-Stout disease: a case report.

Background: Gorham-Stout disease is a rare condition of unknown prevalence and unknown exact cause. Its pathogenesis is based on enhanced osteoclastic activity leading to bone resorption and bone replacement by distended lymphatic vessels. Because of its rarity and a various range of symptoms the disease may give, diagnosis is challenging and a strong index of suspicion is required.

Differences in free flaps' reconstructions with and without coupling device for venous anastomosis.

<br><b>Introduction:</b> Introduction of the coupler devices for anastomoses of neck vessels changes planning and performance of the surgical procedures. The Rigid ring of the coupling devices keeps a vein open and less prone to occlusion. Therefore, this should improve the flap survival rate and surgery duration.

Comparison of criteria for elective tracheostomy in head and neck cancer surgery.

Objectives: Elective tracheostomy before resection of a malignancy in head and neck region assures unobstructed ventilation during postoperative period but is associated with an increased risk of complications. We aimed to evaluate retrospectively, how application of elective tracheostomy scales would influence frequency of tracheostomy in comparison with preoperative clinical judgement.

Methods: In 205 patients operated from 2013 till 2017 resection of a malignancy involved suprahyoid or pharyngeal muscles, neck dissection and flap reconstruction.
