Consultation with a specialized pain clinic reduces pain after oral and maxillofacial surgery.

PURPOSE: Postoperative pain management is important for improved patient care. Our primary objective was to investigate the effect of analgesic treatment adaptation by the pain clinic on postoperative pain relief at an oral and maxillofacial surgery department. Additionally, we aimed to present patients' pain characteristics and the administered analgesic treatment.

MATERIALS AND METHODS: A total of 128 patients treated at our clinic in the period 2012-2015 who required analgesic treatment adaptation by our pain clinic were included. They were further divided into 10 groups: tumor, temporomandibular joint disorder, tooth extraction, osteomyelitis, bisphosphonate-related osteonecrosis of the jaw, submandibular abscess, orthognathic surgery, cyst, sinusitis, and fracture. Pain characteristics evaluated were intensity on a numerical rating scale (NRS) before and after intervention of the pain clinic, quality, genesis, and type.

RESULTS: Post treatment pain intensity values at rest 1.8 (SD: 1.4) and on exercise (walking and physical therapy) 4 (SD: 2) were statistically significant better compared to pretreatment values (4.2, SD: 2.5, and 6.8 SD: 2, respectively). The highest pain intensities were reported after tooth extractions, orthognathic surgery, cystectomies, and fracture reposition. Pain was mainly continuous and related to a combination of a somatic and a neuropathic pathophysiological mechanism.

CONCLUSIONS: Intervention by a specialized pain clinic leads to reduction of postoperative pain.
