A retrospective study was conducted on patients with upper aerodigestive tr
act foreign bodies requiring operative intervention over a 12-year period t
o aid in the recognition and management of foreign body associated complica
tions. Oesophagoscopies were performed for the removal of foreign bodies in
37 patients, age one to 82 years with a male to female ratio of 1.2:1. Ret
ropharyngeal abscesses accounted for eight of 11 foreign body-associated co
mplications. Fish bones were the cause in six cases, chicken bone and a pen
refill in one case each. An abscess was already present at the time of ini
tial procedure in six cases and developed in two cases after successful rem
oval of the foreign body. A high level of suspicion for a retropharyngeal a
bscess should be maintained in cases with perforation, and in patients with
