ABSTRACT
Stylocarotid artery syndrome is a rare condition resulted from compression of the internal or external carotid artery by the styloid process of temporal bone. Patient was presented with left limbs weakness, then compression of the right carotid artery by elongated styloid process was found. He was treated by styloid process truncation with hybrid technique. After operation, compression of carotid artery was relieved. No arterial perforation or dissection happened. This case demonstrated that treatment of carotid artery stylocarotid syndrome with hybrid operation that combines endovascular techniques, radiological imaging and surgical resection can be minimally invasive, safe and effective.
ABSTRACT
The styloid process of the temporal bone is an elongated bony projection presenting a variable length asdemonstrated in osteometric and radiological studies conducted with different techniques: three-dimensionalcomputed tomography (3dct) or dental panoramic three-dimensional scanning. An elongated styloid processcan cause neck pain , dysphagia, headache, sore throat, ear pain, mandibular dysfunction which characterizeEagle’s syndrome. Here we present a rare image of an abnormally long styloid process with ossification of leftstylohyoid ligament belonging to a bone collection of the local anatomical museum , part of our department,and discovered during routine osteology classes .Also if a direct relation between the length of the styloidprocess and syndrome of Eagle is not always obvious ,radiologists , neurologists,neurosurgeons, dentists,anesthetists and otolaryngologists could be aware of this bone anomaly to diagnose this syndrome
ABSTRACT
Skeletal remains are crucial in forensic identification of the sex, especially human skulls including the styloid process, a bony projection from the skull. Hence, the objectives of the present study were undertaken to assess the value of the styloid process for the sex identification of unknown skulls and also to investigate the prevalence of elongated styloid process in 102 human dry skulls from the northeast Thai population. As a result, the interstyloid distances at both base and tip of the styloid processes were found to be significantly different between male and female specimens, although no significant difference was found in the length of the styloid process between males and females. In addition, the occurrence of the elongated styloid process was not associated with the gender, although its prevalent laterality on the left was recognized. It is suggested that the styloid process can be applied to the sex identification by measuring the interstyloid distance at the base or the tip of these processes.
Los restos óseos son cruciales para la identificación forense del sexo, especialmente en los cráneos humanos, incluyendo el proceso estiloides, una proyección ósea del cráneo. Por lo tanto, los objetivos del presente estudio consistieron en evaluar el valor del proceso estiloides en la identificación del sexo de cráneos desconocidos y también para investigar la prevalencia del proceso estiloides elongado en 102 cráneos secos humanos de la población del Noreste de Tailandia. Como resultado, se encontró que las distancias inter-estiloides tanto en la base y la punta de los procesos estiloides eran significativamente diferentes entre las muestras de hombres y mujeres, aunque no se encontró diferencia significativa en la presencia del proceso estiloides entre ambos. Además, la aparición del proceso estiloides elongado no se asoció con el sexo, aún cuando se observó su prevalencia en el lado izquierdo. Sugerimos que el proceso estiloides se puede utilizar en la identificación del sexo mediante la medición de la distancia inter-estiloide en la base o en la punta de estos procesos.

Introduction: Styloid process is a part of temporal bone. It measures 2 to 3 cms in length and lies antero-medial to the mastoid process. An elongated styloid process can compress the vital vessels and nerves close to it. This can lead to pain, foreign body sensation in the pharyngeal region and can also cause dysphagia. Observation: During routine dissection, we encountered elongated styloid process in two cadavers. In one it was unilateral and in another it was bilateral. The measurements of the elongated styloid process were taken using digital Vernier slide calipers. Conclusion: The awareness of the embryological cause and the clinical implications of an elongated styloid process are important for accurate diagnosis and treatment
ABSTRACT
Eagle's syndrome is a disease caused by an elongated styloid process or calcified stylohyoid ligament. Eagle defined the disorder in 1937 by describing clinical findings related to an elongated styloid process, which is one of the numerous causes of pain in the craniofacial and cervical region. The prevalence of individuals with this anatomic abnormality in the adult population is estimated to be 4% with 0.16% of these individuals reported to be symptomatic. Eagle's syndrome is usually characterized by neck, throat, or ear pain; pharyngeal foreign body sensation; dysphagia; pain upon head movement; and headache. The diagnosis of Eagle's syndrome must be made in association with data from the clinical history, physical examination, and imaging studies. Patients with increased symptom severity require surgical excision of the styloid process, which can be performed through an intraoral or an extraoral approach. Here, we report a rare case of stylohyoid ligament bilaterally elongated to more than 60 mm in a 51-year-old female. We did a surgery by extraoral approach and patient's symptom was improved.

The close proximity of the styloid process to many of the vital neurovascular structures in the neck makes it clinically significant. The styloid process is said to be elongated if it is longer than 3.0 cm in length. Anatomical variations are very common and clinical symptoms arising from such variations have to be recognized. Elongated styloid processes may cause chronic throat pain along with foreign body sensation, dysphagia, vague facial pain, and otalgia. Surgical excision of an elongated styloid is considered as a satisfactory treatment for such cases. Here, we present a unique case of bilaterally elongated styloids that could be visualized just by depressing the tongue, when they appeared like the tusks of an elephant in the oropharyngeal region.

Styloid syndrome is characterized by an elongated styloid process or calcification of the stylomandibular and stylohyoid ligament. This study describes a case of a 65-year-old woman who presented to the Stomatology Clinic, University of Marilia with temporomandibular joint pain, ear ringing and a reduced ability to open the mouth. Panoramic and posteroanterior digital radiographs showed bilateral elongation of the styloid processes, especially of the right side, whose length extended beyond the mandible angle. The diagnosis was confirmed with the association of clinical data and image examinations. The treatment options for styloid Syndrome include clinical follow-up, surgical removal of the styloid process or fracture of the elongated process. The case was managed by providing prosthetic rehabilitation and clinical follow-up, observing the level of discomfort and the benefit that could be achieved by the therapy, and avoiding surgical intervention.
El síndrome estilode (Síndrome de Eagle) se caracteriza por un proceso estiloides alargado o calcificación de los ligamentos estilohioideo y estilomandibular. Este estudio describe el caso de una mujer de 65 años de edad que concurrió a la Clínica Estomatológica de la Universidad de Marilia con dolor de la articulación temporomandibular, zumbido en los oídos y una disminución de la capacidad de abrir la boca. Las radiografías digitales panorámica y posteroanterior mostraron alargamiento bilateral de los procesos estiloides, especialmente del lado derecho, cuya longitud se extendió más allá del ángulo de la mandíbula. El diagnóstico se confirmó con la asociación de los datos clínicos y los exámenes de imagen. Las opciones de tratamiento para el síndrome estiloide incluyen el seguimiento clínico, la extirpación quirúrgica del proceso estiloides o la fractura del proceso alargado. El caso fue tratado con rehabilitación protésica y seguimiento clínico, observando el nivel de molestia y el beneficio que se podría lograr mediante la terapia, evitando la intervención quirúrgica.

Objectives: Elongated styloid process was reported concerning dento-maxillofacial and ear-nose-throat patients. Several studies described that its length as well as the anterior and medial angulations occasionally involved in the symptom of Eagle’s syndrome and the surgical shortening of the process could alleviate neck and cervicofacial pain in patients. This study aimed to investigate the length and the angulation of the styloid process, and to study the occurrence of the elongated styloid process in Thais. Methods: The investigation was done in both sides of 176 Thai dry and 150 cadaveric skulls with intact styloid processes. The length and the angulation (anterior and medial angles) of the styloid process were measured and expressed as Mean±SD. A styloid process longer than 30 mm was identified as an elongated styloid process. Results: The means of length, and anterior and medial angles of styloid process were 24.12 ± 7.28 mm, and 28.03 ± 9.85 and 23.53 ± 10.19 degrees, respectively. Out of all styloid processes, 18.40% (11.70% in males, 6.70% in females) were the elongated styloid process. There was no statistical difference of angles between groups with normal and elongated styloid processes (P>0.05). Conclusions: The elongated styloid processes were found up to 18.40% of Thais. The presence of the elongated styloid process and its angulation, though rare, does highlight the importance of routine examination of the styloid process as it may cause pain in craniocervical region.
ABSTRACT
The styloid process is a cylindrical, long cartilaginous bone located on the temporal bone. The calcified stylohyoid ligament and elongated styloid process can be identified radiographically, and they are associated with a number of syndromes and symptoms. The exact cause of the styloid process elongation due to calcification and subsequent ossification of ligament is unclear. This report presents a case of severely calcified stylohyoid ligament complex occurred in twins who have the same pattern of calcification.
