Eagle’s syndrome represent as a neck, cervicofacial pain, dysphagia, facial pain, globus sensation, tinnitus, otalgia and headache, it may be unilateral or bilateral. About 4% of adult population accounted elongated styloid process, which are the principal factor of Eagle’s syndrome and followed by 0.16% of patients are symptomatic. Stylohyoid ligament calcification is the second most common factor. The diagnosis must be made through a detailed history, clinical examination, and various imaging modalities. A 36 years old female patient presented with persistent pain in the throat. An elongated styloid process was diagnosed and was removed by transoral approach following the patient was relieved from her symptoms. J Bangladesh Coll Phys Surg 2022; 40: 72-74

Styloid process elongation associated with symptoms such as cervicofacial pain, tinnitus and otalgia is called Eagle Syndrome. The objective of this study is to assess the presence of elongated styloid process through panoramic radiographs, in a subpopulation of the State of Para, Brazil, as to age and sex. Panoramic radiographs were selected and the apparent size of the styloid process was measured from the point where the styloid leaves the tympanic plate to the lower tip of the process. Data were analyzed by means of chi-square tests and the “t” test with a significance level of 5%. Forty-three percent of all elongated styloid processes were observed in patients aged between 18 and 35 years old. Of these styloid processes measuring more than 30 mm, there were 815 that showed a Type I elongation pattern, being 98 that showed a Type II calcification pattern and 92 showed a Type III calcification pattern. It is concluded that the Type I elongated styloid process was the most frequent, but no statistically significant correlation was found between the presence of the elongated styloid process and the studied variables.

Background: Eagle syndrome is a rare disorder whereby an elongated styloid process (ESP) causes not only some otolaryngological symptoms, but also cerebrovascular events caused by compression of the carotid artery. In recent years a syndrome, denominated as Eagle jugular syndrome, involving internal jugular vein (IJV) compression caused by an ESP has been proposed as a variation of Eagle syndrome. Clinical impact of the Eagle jugular syndrome on neurosurgical procedures has not been reported yet. Case Description: We present a case of a 68-year-old woman who underwent microvascular decompression for hemifacial spasm of the left side and developed delayed intracranial hemorrhage on postoperative day 3. We also demonstrate that this patient developed ipsilateral IJV stenosis between an ESP and the muscle bundle of the rectus capitis lateralis with antero-flexion neck position, which would induce venous congestion in addition to surgical disruption of emissary vein. Conclusion: This case is the first report demonstrating the association of an ESP with postoperative delayed intracranial hemorrhage. Our report elucidates the importance of the awareness among neurosurgeons of considering the ESP as an important bony anomaly, especially when planning for posterior fossa surgery.

Abstract Background Although the automatic diagnosis of fractures using artificial intelligence (AI) has recently been reported to be more accurate than those by orthopedics specialists, big data with at least 1000 images or more are required for deep learning of the convolutional neural network (CNN) to improve diagnostic accuracy. The aim of this study was to develop an AI system capable of diagnosing distal radius fractures with high accuracy even when learning with relatively small data by learning to use bi-planar X-rays images. Methods VGG16, a learned image recognition model, was used as the CNN. It was modified into a network with two output layers to identify the fractures in plain X-ray images. We augmented 369 plain X-ray anteroposterior images and 360 lateral images of distal radius fractures, as well as 129 anteroposterior images and 125 lateral images of normal wrists to conduct training and diagnostic tests. Similarly, diagnostic tests for fractures of the styloid process of the ulna were conducted using 189 plain X-ray anteroposterior images of fractures and 302 images of the normal styloid process. The distal radius fracture is determined by entering an anteroposterior image of the wrist for testing into the trained AI. If it identifies a fracture, it is diagnosed as the same. However, if the anteroposterior image is determined as normal, the lateral image of the same patient is entered. If a fracture is identified, the final diagnosis is fracture; if the lateral image is identified as normal, the final diagnosis is normal. Results The diagnostic accuracy of distal radius fractures and fractures of the styloid process of the ulna were 98.0 ± 1.6% and 91.1 ± 2.5%, respectively. The areas under the receiver operating characteristic curve were 0.991 {n = 540; 95% confidence interval (CI), 0.984–0.999} and 0.956 (n = 450; 95% CI 0.938–0.973). Conclusions Our method resulted in a good diagnostic rate, even when using a relatively small amount of data.

Background. Patients with an elongated styloid process might present with dysphagia and pain in the cervicofacial region. These patients could be misdiagnosed as other orofacial pathologies. Aim. The present study attempted to assess the prevalence of the elongated styloid process on digital panoramic radiographs in the Riyadh population. Materials and Methods. The present prospective randomized study was conducted on the panoramic digital radiographs of 300 randomly selected patients visiting a private dental hospital to identify any elongation of the styloid process. Only the radiographs without any magnification errors were considered. The styloid process length was measured using the Sidexis measuring tool and entered in an Excel spreadsheet with other demographic data. A length beyond 30 mm was considered styloid process elongation. The data were subjected to statistical analysis. Results. The symptoms of styloid process elongation were higher among females (78.6%), and this difference was statistically significant (χ2 = 7.182; P = 0.007 ). No statistically significant association was observed between styloid process elongation and symptoms between different age groups. Females exhibited a significant longer mean length of the styloid process than males. The present study exhibited a 27.3% prevalence for the elongation and calcification of the styloid process. Conclusion. Given the significant prevalence of the elongated styloid process in our study, we recommend it to be considered as one of the differential diagnosis for pain or discomfort in the orofacial region.

Vertebral column is made of 33 vertebrae named as cervical, thoracic, lumbar, sacral and coccygeal vertebrae. Axial skeleton comprises of skull and vertebral column. 12 pairs of cranial nerves and 31 pairs of spinal nerves exit from the central nervous system which control the entire body. Malformations or fusion of vertebrae could be one of the etiologies of nerve compression syndromes. Vital structures emerge out through intervertebral foramina extending from cervical to coccygeal vertebrae. Occipitalisation of atlas, the first cervical vertebra is one of the emergencies leading to wide spectrum of presentations like chronic neck pain or foramen magnum syndrome or unconscious state due to compression of medulla oblongata. During routine examination of skull bones while teaching, one skull was found to exhibit assimilation of atlas. Photographs were captured and compared with normal skull. Thorough examination revealed incomplete occipitalisation of atlas. The anterior arch was completely fused but the posterior arch was bifid showing a split. The styloid process on right side seemed to be long and very close leading to compression of structures of styloid apparatus in addition. On observation, it was found to be a male skull. Fusion of vertebrae may be a congenital anomaly due to maldevelopment of somites in forming vertebrae. Skeletal element of caudal 4th occipital somite forms the occipital bone and when it is fused with the proximal 1st cervical somite leads to occipitalisation of atlas. Acquired conditions like atlantoaxial subluxation, chiari malformations or cervical vertebral fusion or foramen magnum abnormalities have been associated with assimilation of atlas. The present study reports occipitalisation of atlas which is incomplete with a bifid posterior arch. Prevalence of such anomalies may form the differential diagnosis of chronic headache or myelopathies.

The posterior interosseous nerve (PIN) innervates the posterior compartment muscle of the forearm and is a continuation of the deep branch of the radial nerve. The anatomic descriptions of PIN vary among different authors. This study investigated the distribution patterns of PIN and its relationships to the supinator muscle. This study investigated which nerves innervate the posterior compartment muscles of the forearm, the radial nerve, and the PIN, using 28 nonembalmed limbs. Also, the points where the muscle attaches to the bone were investigated. The measured variables in this study were measured from the most prominent point of the lateral epicondyle of the humerus (LEH) to the most distal point of the radius styloid process. For each specimen, the distance between the above two points was assumed to be 100%. The measurement variables were the attachment area of the supinator and branching points from the radial nerve. The attachment points of the supinator to the radius and ulna were 47.9 % ± 3.6 % and 31.5 % ± 5.2 % , respectively, from the LEH. In 67.9% of the specimens, the brachioradialis and extensor carpi radialis longus (ECRL) were innervated by the radial nerve before superficial nerve branching, and the extensor carpi radialis brevis (ECRB) innervated the deep branch of the radial nerve. In 21.4% of the limbs, the nerve innervating the ECRB branched at the same point as the superficial branch of the radial nerve, whereas it branched from the radial nerve in 7.1% of the limbs. In 3.6% of the limbs, the deep branch of the radial nerve branched to innervate the ECRL. PIN was identified as a large branch without divisions in 10.7% and as a deep branch innervating the extensor digitorum in 14.3% of the limbs. The anatomic findings of this study would aid in the diagnosis of PIN syndromes.
