    Introduction One problem using microvascular free flaps is the ipsilateral anastomosis if the ipsilateral vascular situation is impaired. Data on the contralateral anastomosis as an alternative approach are missing.

    Methods In this retrospective, descriptive study data of all patients who had been operated in the ENT department / university hospital Erlangen from 2006-2019 were included. Inclusion criterion was the reconstruction with a microvascular free flap with a contralateral anastomosis i.e. the ipsilateral exit of the vascular pedicle out of the pharyngeal tube and the anastomosis on the contralateral side of the neck.

    Results Out of 607 patients 4,6 %  of the patients received a contralateral microvascular anastomosis. In 96,4 %  a radial forearm flap, in 3,6 %  an anterolateral thigh flap was used. 14,3 %  of the patients had been previously treated. The contralateral connection was chosen in 46,4 %  because the ipsilateral neck dissection had been more radical than the contralateral one and as a consequence the ipsilateral vascular situation was insufficient. In 71,4 %  of the cases the connection with the superior thyroid artery was chosen. For the venous connection, the facial vein was used in 71,4 % . The flap success rate was 96,3 % . Overall, flap associated complications occurred in 14,3 % .

    Summary The success rate in this study was comparable with existing data of patients with ipsilateral microvascular anastomoses. The complication rate of contralateral microvascular anastomoses was not elevated.

    Conclusion In case of a lack of suitable vessels for the ipsilateral anastomosis, the anastomosis on the contralateral side of the neck is an equal option and should be included in the surgical repertoire for the microvascular treatment of the vessel-depleted neck.
