Need for close interdisciplinary communication after endoscopic endonasal surgery to further personalize postoperative radiotherapy in sinonasal malignancies
Comment on ‘Cutaneous manifestations in COVID‐19: a first perspective’ by Recalcati S
International audienceSince the coronavirus disease 2019 (COVID 19) outbreak was first reported in the Chinese city of Wuhan on December 31, 2019, it has stricken more than 1,000,000 persons worldwide, of whom over 50,000 have died (1). Having been infected by severe acute respiratory syndrome coronavirus 2 (SARS‐COV‐2), patients with COVID‐19 mainly present with fever and respiratory symptoms (2). Isolated sudden onset anosmia has also frequently been reported (3). Less frequently, rhinorrhea, diarrhoea and dysgeusia may be associated. While only a few reports have evoked cutaneous manifestations (4), we read with interest an initial study on the topic entitled “Cutaneous manifestations in COVID‐19: a first perspective ” by Recalcati S.

International assessment of interobserver reproducibility of flap delineation in head and neck carcinoma.
Background: Several reports have suggested that radiotherapy after reconstructive surgery for head and neck cancer (HNC), could have deleterious effects on the flaps with respect to functional outcomes. To predict and prevent toxicities, flap delineation should be accurate and reproducible. The objective of the present study was to evaluate the interobserver variability of frequent types of flaps used in HNC, based on the recent GORTEC atlas.Materials and methods: Each member of an international working group (WG) consisting of 14 experts delineated the flaps on a CT set from six patients. Each patient had one of the five most commonly used flaps in HNC: a regional pedicled pectoralis major myocutaneous flap, a local pedicled rotational soft tissue facial artery musculo-mucosal (FAMM) (2 patients), a fasciocutaneous radial forearm free flap, a soft tissue anterolateral thigh (ALT) free flap, or a fibular free flap. The WG's contours were compared to a reference contour, validated by a surgeon and a radiologist specializing in HNC. Contours were considered as reproducible if the median Dice Similarity Coefficient (DSC) was > 0.7.Results: The median volumes of the six flaps delineated by the WG were close to the reference contour value, with approximately 50 cc for the pectoral, fibula, and ALT flaps, 20 cc for the radial forearm, and up to 10 cc for the FAMM. The volumetric ratio was thus close to the optimal value of 100% for all flaps. The median DSC obtained by the WG compared to the reference for the pectoralis flap, the FAMM, the radial forearm flap, ALT flap, and the fibular flap were 0.82, 0.40, 0.76, 0.81, and 0.76, respectively.Conclusions: This study showed that the delineation of four main flaps used for HNC was reproducible. The delineation of the FAMM, however, requires close cooperation between radiologist, surgeon and radiation oncologist because of the poor visibility of this flap on CT and its small size
