Tanaka K, Tsunoda A, Tou M, et al. - Given that drainage in the head and neck area requires cosmetic care, particularly in the pediatric population, researchers presented the method of percutaneous abscess drainage using an indwelling needle cannula in this analysis. Ten pediatric and five adult patients with cervical and/or facial abscess treated with this drainage method have been reviewed retrospectively. Abscesses were penetrated under ultrasonic examination using an indwelling needle cannula (18-14 G Surflow®, Terumo, Tokyo, Japan). According to results, the primary diseases of these abscesses were cervical abscess of dental origin, purulent lymphadenitis, pyriform sinus fistula, and subperiosteal abscess due to mastoiditis, circumorbital cellulitis, infection of Warthin's tumor, and unknown origin. Using an indwelling needle cannula, the percutaneous abscess drainage is not only effective but also simple, minimally invasive, and affordable. The technique is similar to the usual venous placement of an indwelling needle cannula and is thought to be familiar to doctors. No apparent scars have been observed after a drainage.
