For further information about the subject consider the European Study Group for Functional Laryngology (EGFL) supervised paper: Marioni G, Marchese-Ragona R, Kleinsasser NH, Lionello M, Lawson G, Hagen R, Staffieri A.Partial laryngeal surgery in recurrent carcinoma. Acta Otolaryngol. 2015;135:119-24.
I agree absolutely with Prof. Galli that most of the reports on experiences with salvage supracricoid laryngectomies have come from European groups.
Generally speaking, at the time also the interest of the European groups in respect of salvage transoral laser surgery (TLS) seems greater than that of North American groups . Ramakrishnan et al. (Head Neck 2014;36:280-285) very recently analyzed the oncological results of salvage endolaryngeal laser surgery after RT had failed. Up to July 2011, they found 11 studies that met their inclusion criteria (9 of them European and 2 from the United States).
