Cervico-facial pain associated with Eagle's syndrome misdiagnosed as cranio-mandibular disorders. A retrospective study.

AIM OF STUDY: a retrospective study was done to assess symptoms correlated with and responsible for the misdiagnosis of Eagle's syndrome with Cranio-Mandibular Disorders. MATERIALS AND METHODS: Our study comprised patients suffering from vague craniofacial pain resulting from elongated styloid processes, presented to the outpatient clinic of the oral and maxillofacial surgery department, October 6 University Hospital. The length of styloid processes was measured on 3D-CT X-rays. All our patients were operated by surgical treatment in the form of shortening of the styloid process (styloidectomy) under general anaesthesia and followed up clinically as well as radiographically for 12 months. RESULTS: Patients were assessed preoperatively as well as postoperatively throughout the following scheduled regular follow up intervals at 1 week and at 1,3,6 and 12 months postoperatively for the following parameters. VAS pain score gradually decreased from a median of 9, with a minimum of 7 and a maximum of 10 pre-operatively to a median of 1.5, with a minimum of 0 and a maximum of 3 at twelve months. Freidman test revealed a statistically significant difference by time. Maximum unassisted mouth opening was assessed. Mouth opening significantly decreased from 30.23 ± 3.28 pre-operatively to 26.08 ± 2.83 after one week, then gradually increased to reach its highest level (43.56 ± 0.72) at twelve months. CONCLUSION: When dealing with cases of vague craniofacial pain, possibility of Eagle syndrome should be considered.
