Introduction Complete or partial ossification of the pterygospinous ligament that connects the posterior border of the lateral pterygoid plate to the spine of the sphenoid bone occurs in 1-31.2% of people [1,2]. The ossified pterygospinous ligament is detected on the lateral or medial side or crossing over the foramen ovale on the radiographs of the dry scull in the axial projection with the be...
The mouse incisor has two unusual features: it grows continuously and it is covered by enamel exclusively on the labial side. The continuous growth is driven in part by epithelial stem cells in the cervical loop region that can both self-renew and give rise to ameloblasts. We have previously reported that ectopic enamel is found on the lingual side of the incisor in mice with loss-of-function o...
usually located in the middle cranial fossa. Localizations in the posterior fossa are uncommon and generally remain asymptomatic or cause vague and non-specific symptoms. We describe the unusual case of a patient with an AC suffering from recurrent polymorphic vertigo with atypical nistagmus and transient sensorineural hearing loss. The clinical-diagnostic features are discussed, etiopathogenic...
We present the first report of a patient with atypical hemifacial microsomia (HFM) and unilateral aplasia of the floor of the middle cranial fossa, glenoid fossa, and portions of her posterior fossa. The patient also developed a Chiari I malformation with cervical syrinx over a 3-year interval. This case report highlights the critical role of imaging in revealing serious, but clinically occult,...
Variations of the posterior fossa blood supply are relatively uncommon but should be borne in mind by the clinician. We present two unusual cases of posterior cranial fossa blood supply and review the literature regarding such abnormalities. Both cases demonstrated a lack of the vertebrobasilar system to varying degrees. Such arterial variations as present herein should be known to the clinicia...
Neurenteric cysts (NC) are rare, endodermal-derived intracranial lesions, commonly located anteriorly in the posterior cranial fossa. We describe a rare case of a giant posterior fossa NC (6.5 × 5.9 × 4.3cm) located dorsal to the brain stem in a Chinese woman with a 1 week history of cerebellar symptoms. To our knowledge, this is the largest documented cyst of this type and the third dorsally l...
To the Editor: Goyal et al recently published an anatomic study about the surgical anatomy of the supraglottic larynx using the da Vinci robot. In this publication, the course of lingual artery has been described as lateral to hyoglossus muscle, which separates the artery from the lingual nerve. The authors exposed the lingual artery while describing the endoscopic anatomy of the supraglottic l...
It is difficult to visualize the lingual surfaces of the all tooth, in order to assess the exact Facial axis of the clinical crown (FACC point) . So no matter how accurately brackets are positioned on set-up models, it would be meaningless if these positions were lost during intraoral bracket placement. It is no exaggeration to say that incorrect bracket positioning leads to treatment failure. ...
Lingual tumors are rare, primarily benign, lesions in the pediatric population. Congenital lesions, such as hemangiomas, lymphatic malformations, dermoids, hamartomas and thyroglossal ducts cysts, are seen more commonly. Primary, non-congenital lingual neoplasms are less common in children. We present three patients with benign lingual neoplasms. Evaluation, management, pathology and follow-up ...
Statistical Parametric Speech Synthesis (SPSS) offers flexibility and computational advantage compared to other methods for Text-to-Speech Synthesis. While the speech output is intelligible, statistically trained voices are less natural due to the amount of signal processing and statistical averaging that goes into building the models. Much of the blame for the lack of naturalness falls on the ...
