Abstract-Text |
Purpose. The frequency of ocular symptoms in patients with trigeminal neuralgia (TN) based on multidisciplinary diagnostics was evaluated in this study. Methods. This population study consisted of 60 consecutive patients (mean age ± SD was 51.53 ± 13.83 years, range of age 26-88 years, 72% were female) who were referred to the Department of Removable Prosthodontics. For the purpose of obtaining a differential diagnosis, a number of the patients were referred from the neurologist. The patients were distributed with respect to the involvement of the trigeminal nerve’s ophthalmic branch: Subgroup 1 – patients with the ophthalmic branch involvement, and Subgroup 2 – only the maxillary and/or mandibular branch involved. Pain intensity was rated on the visual-analogue scale (VAS). Results. Involvement of the ophthalmic branch was determined in 17 (34%) patients (Subgroup 1, mean age ± SD was 47.17 ± 14.13 years, range of age 26-67 years). In 7 of the patients all three branches of the trigeminal nerve were involved and in 10 patients it was a combination of the ophthalmic and just the maxillary branch. Neuropathic pain intensity was 9.04 ± 1.39 on VAS. In Subgroup 2 (43 patients; mean age ± SD was 55.58 ± 13.53 years, range of age 25-88 years) the involvement of the combination of the maxillary and mandibular branches was found in 15 patients, the involvement of only the maxillary branch in 17 patients and only the mandibular branch in 11 patients. There were no statistically significant differences between the subgroups with respect to age (t test(df59)=2.06601, p=0.022) or pain intensity (t test(df59)=0.06609, p=0.474). Summary frequency of the involvement of individual trigeminal nerve branches regardless of the individual patients was the following: ophthalmic branch 17.2%, maxillary 49.5% and mandibular branch 33.3%. There were no patients with neuralgia of the ophthalmic branch alone nor those with a combination of ophthalmic and mandibular branch symptoms. Conclusion. It is difficult to determine the prevalence of TN because the disease is often not recognized as neuralgia and therefore, in dental practice, the symptomatology is often initially related to odontogenic pain of unclear etiology. The involvement of ophthalmic branches is the rarest form of clinical cases of neuropathic orofacial pain caused by TN. |
