Jq. Swift et Mt. Roszkowski, THE USE OF OPIOID DRUGS IN MANAGEMENT OF CHRONIC OROFACIAL PAIN, Journal of oral and maxillofacial surgery, 56(9), 1998, pp. 1081-1085
The use of opioid analgesics for the management of patients with chron
ic pain is controversial. However, randomized and double-blind clinica
l trials have shown that in select groups of patients with chronic pai
n, the daily administration of oral opioids decreases pain levels and
improves quality of life. This article provides a review of the most r
ecent basic and clinical research supporting the rationale For the use
of opioids in a select group of patients with chronic orofacial pain.
Critical to the employment of this technique are proper patient evalu
ation and use of comprehensive management strategies. This management
scheme should be reserved for patients with chronic pain that is refra
ctory to most nonopioid therapy. The primary reason for the clinician'
s reluctance to initiate long-term opioid therapy for their patients w
ith chronic pain is the potential risk of developing opioid tolerance,
dependence, or addiction. In contrast to these beliefs, studies have
shown a nonexistent to low risk of opioid dependence or addiction beha
vior with administration of scheduled oral opioids in chronic pain pat
ients. It is essential that potential patients for this type of therap
y have been carefully screened and have not had a history of drug addi
ction. The criteria to be evaluated when considering opioid therapy fo
r chronic orofacial pain control include 1) inadequate pain diminution
from prior nonopioid therapy, 2) negative history of substance abuse,
3) definitive determination that the pain being treated is of physiol
ogic rather than psychologic origin, 4) a willingness to adhere to an
''opioid contract'' between the doctor and patient, 5) compliance with
a scheduled, rather than ''as needed'' or ''breakthrough,'' administr
ation of an oral opioid, and 6) close clinical follow-vp to evaluate p
ain relief, return to daily activities, and titration of drug levels.
If these criteria are followed, administration of oral opioids may be
a successful means of decreasing the patient's debilitating chronic pa
in to tolerable levels, enabling an improvement in the quality of life
and return to function.
