Eagle Syndrome: An Unusual Cause Limited Mouth Opening and Surgical Management.

Eagle syndrome, defined "stylalgia," occurs when an elongated styloid process or calcified stylohyoid ligament causes dysphagia, facial pain recurrent throat pain or foreign body sensation, also associated symptoms such as neck or throat pain with radiation to the ear. The symptoms related to this condition can be confused or misdiagnosed to a wide variety of facial neuralgias. The incidence of Eagle syndrome varies among population. Usually asymptomatic, it occurs in adult patients, and can be diagnosed by physical examination and radiologically. A 30-year-old male patient presented to the maxillofacial unit of Sulaimaniyah Teaching Hospital with a complaint of pain in the right side of face interfering with mouth opening and causing deviation to the right side of mouth for 6 months duration. The elongated styloid process of the right side was resected surgically by the intra-oral approach. The patient was asymptomatic and comfortably followed up for 5 months.

Stereotactic radiosurgical treatment of sphenopalatine neuralgia. Case report.

Sphenopalatine neuralgia is a rare craniofacial pain syndrome that is characterized by unilateral pain in the orbit, mouth, nose, and posterior mastoid process. During attacks of pain, vasomotor activity often results in ipsilateral nasal drainage, eye irritation, and lacrimation. The authors present a patient with a 15-year history of sphenopalatine neuralgia who underwent stereotactic radiosurgery targeted at the sphenopalatine ganglion, with initial pain relief, and repeated radiosurgery 17 months later for partial pain recurrence. Two years following radiosurgery, the patient is pain free, no longer suffering from nasal discharge and eye irritation.

Endoscopic section of the sensory trigeminal root, the glossopharyngeal nerve, and the cranial part of the vagus for intractable facial pain caused by upper jaw carcinoma.

In a patient with intractable facial pain caused by a deep-seated carcinoma of the upper jaw, relief was obtained following endoscopic section of the sensory trigeminal root, the glossopharyngeal nerve, and the cranial part of the vagus. Previous stereotactic thalamotomy had failed. The endoscopic method is briefly described and discussed.

[Eagle syndrome: diagnostic imaging and therapy]. / Eagle Syndrom-- Bildgebende Diagnostik und Therapie.

In the case of clinical symptoms such as dysphagia, foreign-body sensation and chronic neck or facial pain close to the ear, an Eagle syndrome should be considered in the differential diagnosis. Rational diagnostics and therapy are elucidated on the basis of four case reports. Four patients presented in the outpatients clinic with chronic complaints on chewing and a foreign-body sensation in the tonsil region. Upon specific palpation below the mandibular angle, pain radiating into the ear region intensified. In all patients, local anaesthesia with lidocaine only led to a temporary remission of symptoms. Imaging diagnostics then performed initially included cranial survey radiograms according to Clementschitsch as well as in the lateral ray path and an OPTG. An axial spiral-CT was then performed using the thin-layer technique with subsequent 3-D reconstruction. Therapy consisted of elective resection with a lateral external incision from the retromandibular. From a symptomatic point of view, the cranial survey radiograms and the OPTG revealed hypertrophic styloid processes. The geometrically corrected addition of the axial CT images produced an absolute length of 51-58 mm. The 3-D reconstruction made it possible to visualise the exact spatial orientation of the styloid processes. An ossification of the stylohyoid ligament could definitely be ruled out on the basis of the imaging procedures. After resection of the megastyloid, the patients were completely free of symptoms. Spiral-CT with subsequent 3-D reconstruction is the method of choice for exact determination of the localisation and size of a megastyloid, while cranial survey radiograms according to Clementschitsch and in the lateral ray path or an OPTG can provide initial information. The therapy of choice is considered to be resection of the megastyloid, whereby an external lateral incision has proved effective.

Long-term effects of jawbone curettage on the pain of facial neuralgia.

PURPOSE: To evaluate the dimension and duration of pain reduction in patients with facial neuralgias after localization, decortication, and curettage of histologically confirmed inflammatory jawbone lesions of the newly identified form of alveolar avascular osteonecrosis called neuralgia-inducing cavitational osteonecrosis (NICO). MATERIALS AND METHODS: One hundred ninety patients who could be located retrospectively and who had histories of jawbone curettage for chronic "idiopathic" facial pain, either trigeminal neuralgia (TN) or atypical facial neuralgia/pain (AFN), were identified through surgical pathology reports from four institutions. To assess pain reduction after jawbone surgery, these patients were mailed a modified McGill Pain Survey by investigators with whom they had had no previous professional contact. Patient demographics and clinicopathologic characteristics were also reviewed through surgical pathology specimens and reports. RESULTS: More than two thirds of the respondents to whom the questionnaire was mailed experienced complete or almost complete disappearance of neuralgic pain immediately or shortly after curettage of jawbone osteonecrosis (NICO), regardless of whether they had previously been diagnosed with TN or AFN. Thirty percent, however, experienced local recurrence of jaw inflammation and facial pain, and one third developed at least one and as many as 12 additional foci of histologically confirmed osteonecrosis. Despite this, however, the long-term (average, 4.6 years) abatement of neuralgic pain was total or almost total in 74% of treated patients. CONCLUSIONS: Neuraglia-inducing cavitational osteonecrosis appears to be associated with at least some cases of facial neuralgia, or with a pain so similar as to be clinically indistinguishable. Decortication and curettage dramatically reduces or eliminates this intense pain in two of every three patients, although multiple surgeries may be required, and additional sites of osteonecrosis may occur. It is recommended that NICO be included in the differential diagnosis of idiopathic facial pain syndromes.

Etiology and treatment of idiopathic trigeminal and atypical facial neuralgias.

In a series of sixteen patients with idiopathic trigeminal neuralgia and twenty-one patients with atypical facial neuralgia, it was found that the painful phenomena associated with both disorders were, in nearly all instances, closely related to the presence of maxillary or mandibular bone cavities at previous tooth extraction sites. Standard oral surgical procedures for curettage of the cavities, together with administration of antibiotics, were employed in the successful treatment of both the trigeminal and atypical facial neuralgias, with complete pain remissions for periods varying from 2 months (for most recently treated cases) up to 9 years. The observations and results of this study suggest that dental and oral disorders may play a role in the genesis of trigeminal and atypical facial neuralgias.

Further observations on dental parameters of trigeminal and atypical facial neuralgias.

One hundred thirty-one patients with primary trigeminal neuralgia and 77 patients with atypical facial neuralgia or pain were treated by oral surgical procedures, with complete or almost complete pain remission in 88% of the cases and without persistent residual anesthesias, dysesthesias, or dysalgesias. The following conditions were related to patients' pain perceptions: cavities in alveolar bone at tooth extraction sites, bone fistulas, periodontal infections, and maxillary sinus infections draining into alveolar bone. The bone cavities and fistulas mentioned above were usually not visualized by standard x-ray diagnostic procedures, and their detection required a new diagnostic approach which is described. Microbiologic findings indicated involvement of a mixed, variable flora in the above conditions. Histopathologic observations of scrapings from involved bone showed a variable incidence of bone necrosis, predominantly chronic inflammatory cell populations and fibrous tissue.
