Patients and methods
This is a retrospective study. Twenty-six ALH patients who underwent 29
different procedures between them—conventional chemotherapy or ALH
excision—at our department between June 2012 and March 2021 were
enrolled in the study. The patients were divided into two groups, the
ALH excision group (9 cases) and the conventional chemotherapy group (20
cases). The 20 cases in the conventional chemotherapy group received
bleomycin injections. In the ALH excision group, three cases underwent
“cold as a surgical instrument” therapy (which included the use of
micro laryngeal forceps and micro laryngeal microscissors); two cases
underwent holmium laser therapy; and
four cases underwent CO2 laser therapy.
ALH diagnoses were made based on patient history,
laryngoscopic findings, and
contrast-enhanced computed tomography (CT) (Figure 1). All the surgeries
were preformed under general anesthesia using a suspension micro
laryngoscope. In the ALH excision group, hemangioma classification was
done based on histopathological examination. However, in the
conventional chemotherapy group, hemangioma classification was done
based on morphology, according to the classification of tracheal
hemangiomas3,4.
