Eagle syndrome: a narrative review / Síndrome de Eagle: una revisión narrativa

Abstract: painful disorders in the maxillofacial region are common in dental practice. Most of these conditions are not properly diagnosed because of inadequate knowledge of craniofacial and cervico-pharyngeal syndromes such as Eagle Syndrome. The aim of this review is to describe the general aspects, diagnosis and treatment of Eagle syndrome. Eagle syndrome or stylohyoid syndrome was first described by Watt W. Eagle in 1937. It was defined as orofacial pain related to the elongation of the styloid process and ligament stylohyoid calcification. The condition is accompanied by symptoms such as dysphonia, dysphagia, sore throat, glossitis, earache, tonsillitis, facial pain, headache, pain in the temporomandibular joint and inability to perform lateral movements of the neck. Diagnosis and treatment of Eagle syndrome based on symptoms and radiographic examination of the patient will determine the need for surgical or nonsurgical treatment. Eagle syndrome is a complex disorder demanding a thorough knowledge of its signs and symptoms to make a correct diagnosis and provide an appropriate subsequent treatment. Disseminating information about this syndrome among medical-dental professionals is essential to provide adequate dental care to patients.

Resumen: en la práctica odontológica, es frecuente encontrar alteraciones con sintomatología dolorosa en la región maxilofacial, las cuales no son apropiadamente diagnosticadas, a causa del desconocimiento de síndromes craneofaciales y cervicofaríngeos, como el Síndrome de Eagle. El objetivo de esta revisión es describir los aspectos generales, diagnóstico y tratamiento del Síndrome de Eagle. El Síndrome de Eagle o estilalgia es la entidad nosológica, descrita por Watt W. Eagle en 1937, definida como aquel dolor orofacial relacionado con la elongación de la apófisis estiloides y calcificación del ligamento estilohioideo; el cual está acompañado de síntomas como: disfonía, disfagia, dolor faríngeo, glositis, otalgia, tonsilitis, dolor facial, cefalea, odinofagia, dolor en la articulación temporomandibular e imposibilidad de realizar movimientos laterales del cuello. El diagnóstico y tratamiento del Síndrome de Eagle está basado en la sintomatología y el examen radiográfico del paciente, lo cual determinará el tratamiento quirúrgico o no quirúrgico. El Síndrome de Eagle es una patología compleja que requiere un conocimiento amplio de sus signos y síntomas, para establecer un correcto diagnóstico y posteriormente un adecuado tratamiento. Para ello, es necesario difundir la información sobre este síndrome entre los profesionales médico-odontológico y así brindar una atención adecuada a cada uno de los pacientes.

Síndrome de Eagle: revisión de la literatura / Eagle syndrome: literature review

El síndrome de Eagle es una condición infrecuente caracterizada por una elongación de la apófisis estiloides y/o una calcificación del ligamento estilohioideo. Clinicamente los pacientes presentan una larga historia de dolor crónico cervicofacial, tratado por múltiples especialistas y mediante variadas estrategias terapéuticas. El diagnóstico requiere de un alto índice de sospecha, basado fundamentalmente en la anamnesis y el examen físico. Presentamos una revisión y actualización sobre el síndrome de Eagle, abarcando sus aspectos clínicos relevantes, su diagnóstico y tratamiento.

Eagle syndrome is a rare condition characterized by an elongation of the styloid process and /or calcification of the stylohyoid ligament. Clinically, patients present with a history of chronic cervicofacial pain, treated by multiple specialists and through various therapeutic strategies. The diagnosis requires a high index of suspicion, based primarily on the history and physical examination. We review and update on Eagle syndrome, covering their relevant clinical aspects, diagnosis and treatment.

Influence of transcutaneous electrical stimulation on heterotopic ossification: an experimental study in Wistar rats

Heterotopic ossification (HO) is a metaplastic biological process in which there is newly formed bone in soft tissues, resulting in joint mobility deficit and pain. Different treatment modalities have been tried to prevent HO development, but there is no consensus on a therapeutic approach. Since electrical stimulation is a widely used resource in physiotherapy practice to stimulate joint mobility, with analgesic and anti-inflammatory effects, its usefulness for HO treatment was investigated. We aimed to identify the influence of electrical stimulation on induced HO in Wistar rats. Thirty-six male rats (350-390 g) were used, and all animals were anesthetized for blood sampling before HO induction, to quantify the serum alkaline phosphatase. HO induction was performed by bone marrow implantation in both quadriceps of the animals, which were then divided into 3 groups: control (CG), transcutaneous electrical nerve stimulation (TENS) group (TG), and functional electrical stimulation (FES) group (FG) with 12 rats each. All animals were anesthetized and electrically stimulated twice per week, for 35 days from induction day. After this period, another blood sample was collected and quadriceps muscles were bilaterally removed for histological and calcium analysis and the rats were killed. Calcium levels in muscles showed significantly lower results when comparing TG and FG (P<0.001) and between TG and CG (P<0.001). Qualitative histological analyses confirmed 100% HO in FG and CG, while in TG the HO was detected in 54.5% of the animals. The effects of the muscle contractions caused by FES increased HO, while anti-inflammatory effects of TENS reduced HO.

Remodelación ósea en espondiloartritis / Bone remodeling in spondyloarthritis

Spondyloarthritis is a group of several related but phenotypically distinct chronic inflammatory diseases, characterized by progressive new bone formation which leads to ankylosis and functional disability. Radiographic images evidence not only erosive changes but also overgrowth of bony structures called syndesmophytes. These inflammation, bone destruction and new bone formation are located in the entheses, which constitutes the primary organ of the disease. As a consequence, the inflammatory process results in excess of bone formation and the impact depends on the location, cell type, cytokines and local microenvironment factors. Several molecules playing a role as immune modulators or regulators of bone homeostasis, mediate the imbalance between bone resorption and formation. In the same way, animal models suggest that joint ankylosis may be independent from the effects of tumor necrosis factor alpha. Therefore, the process of new tissue (bone) formation can be considered as an additional therapeutic target. The Wnt signaling pathway, which is considered the primary regulator of osteoblastogenesis, constitutes a new research field of great interest in the last decade.

Lesões múltiplas de osteoma cutis na face: terapêutica minimamente invasiva em pacientes com sequela de acne - relato de casos / Multiple injuries of osteoma skin in the face: therapeutical least invasive in patients with acne sequela - case report

Osteoma cutis é a formação óssea no interior da pele, podendo ser primária ou secundária. Única ou múltipla, de tamanhos variados e acometendo ambos os sexos, é uma lesão cutânea rara, de etiopatogenia e classificação ainda discutidas. Nosso objetivo foi relatar o diagnóstico e a terapêutica minimamente invasiva de lesões múltiplas de osteoma cutis na face em pacientes com sequelas de acne. Fizemos a retirada dos osteomas com agulhas BD 0,70 x 25 22G1, sem anestésicos tópicos ou injetáveis no local. As pequenas incisões foram deixadas expostas, com pomada cicatrizante. Obteve-se um excelente resultado estético em 15 dias.

Osteoma cutis is a bone formation in the dermis can to be primary or secondary forms. Only, multiples, many forms, occurring on either sex, they are a rare cutaneous disease. The pathogenesis and classification remains unclear. Our objective was the diagnostic and small invasive surgery treatment of the osteoma cutis multiple of the face, in patients as a sequel of acne. To remove the osteoma we used needle BD 0,70x25 22G1, without anesthetic topic or inject able site. The small wounds were exposed with scarring balsam. We got an excellent esthetic result after 15 days.

Sindrome de Eagle en otorrinolaringología / Eagle syndrome in otolaryngology

Eagle syndrome is characterized by recurrent clinical symptoms like globus, dysphagia and odynophagia, which can be explain by an abnormal elongation of the Estiloid Apophysis or the calcification of the estilohioid ligament. It affects in equal proportion to men and women, being most common in people older than 50 years. Its importance is that it appears as a differential diagnosis compared with other causes of cervicofacial pain, being its election treatment, the surgical resection of the Estiloid apophysis. The following is a review of the literature and a clinical case of a 44 years old man, who consulted with a history of 6 months of odynophagia, foreign body sensation and cervicalgia. After the clinical, endoscopic and the complementary study of images evaluation, it was concluded that this was an Eagle Syndrome.
