1/33. Mental nerve neuropathy as a result of primary herpes simplex virus infection in the oral cavity. A case report.We describe a 25-year-old woman who had mental nerve neuropathy. The symptom was attributed to herpes simplex virus infection, which appeared as herpetic gingivostomatitis 4 days after the extraction of the lower third molar. This case suggests that herpes simplex virus can infect the inferior alveolar nerve through an extraction wound and can induce mental nerve neuropathy.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
2/33. tongue piercing. The new "rusty nail"?BACKGROUND: Cephalic tetanus is a rare form of the tetanus caused primarily by wounds or other infectious processes involving the head and neck. This condition frequently progresses to the generalized form of tetanus with the attendant risks and complications. methods: A case report of a young female who developed an unusual form of tetanus after a tongue piercing is presented here. We discuss this disorder as it applies to the contemporary caregiver with a focus on its presentation and recognition. RESULTS: A delay in diagnosis of 13 days from presentation occurred. The patient had a slow, uneventful but incomplete recovery course. She never developed significant airway compromise, nor did she demonstrate any evidence of hemodynamic instability but continued to have right facial weakness up to 6 months after discharge. CONCLUSIONS: A few factors were identified that contributed to the significant delay in diagnosis. The unusual nature of the disease and a lowered index of suspicion on the part of the initial caregivers were probably the major causes. Fortunately, no major adverse sequelae resulted from the delay. However, if this case heralds the onset of a rise in the incidence of tetanus, early recognition and diagnosis would seem essential to avoid much of the morbidity and mortality associated with the disease.- - - - - - - - - - ranking = 0.014107940369076keywords = process (Clic here for more details about this article) |
3/33. Pituitary abscess presenting with cranial nerve paresis. Case report and review of literature.Non-adenomatosus lesions of the pituitary represent a small part of the intrasellar processes and they have heterogeneous presentation. Making a precise diagnosis is of great importance, as it may lead to more efficient management. A 65-year-old man was admitted to the hospital because of headache and right cranial nerve III palsy. Basic laboratory work-up was normal whereas endocrinological assessment revealed hypopituitarism without diabetes insipidus. Plain radiography showed an enlarged sella and frontal and paranasal sinusitis. Computed tomography (CT) and magnetic resonance imaging (MRI) of the sella revealed an intrasellar lesion with extension to the sphenoid and cavernous sinuses as well as the suprasellar region, exerting pressure on the optic chiasm. On T1-weighted images the mass had a low-intensity signal with a smooth enhancing rim with bright signal. Given the presence of multiple sinusitis and imaging characteristics a pre-operative diagnosis of pituitary abscess was made. The patient was operated via transphenoidal route and purulent material was drained out. Cultures of the material were positive for staphylococcus aureus. Antibiotics as well as cortisol replacement therapy were given. Three months later hypopituitarism persisted but there was significant improvement in the neurological findings. We report a case of an unusual presentation of a pituitary abscess. High index of suspicion, the presence of associated conditions such as pituitary tumors, meningitis or sinusitis, as well as diabetes insipidus and specific imaging features are the main diagnostic clues. Pre-operative diagnosis, which will lead to prompt antibiotic therapy and transphenoidal drainage, can decrease high mortality and morbidity associated with this disease.- - - - - - - - - - ranking = 0.014107940369076keywords = process (Clic here for more details about this article) |
4/33. Lesions of the inferior alveolar nerve arising from endodontic treatment.A lesion of the IAN following endodontic treatment of the lower molars and premolars is not a rare event and presents an uncomfortable situation both for the dental surgeon and the patient. Injury can result on the one hand by direct intrusion of the instrument through the apex into the mandibular canal, and on the other by the filling material which becomes forced into the mandibular canal. In the latter case, a nerve lesion will only result when the filling material contains neurotoxic substances such as paraformaldehyde. With a direct lesion or when forcing of resorbable filling material into the mandibular canal is suspected, one should first employ a wait-and-see approach, because usually the only nerve damage is in the form of neuropraxy or axonotmesis for which there is a high rate of spontaneous regeneration. However, if neurotoxic filling material is introduced into the direct vicinity of the nerves, the mandibular canal should be opened and the filling material should be removed as early as possible. If the filling material is forced directly within the endoneurium between the nerve bundles, the damaged nerve sections must be resected and bridged using transplants from the sural or greater auricular nerves.- - - - - - - - - - ranking = 4keywords = alveolar (Clic here for more details about this article) |
5/33. An unusual association between oral sarcoma and bulbar palsy.A 90 year old male presented with symptoms and signs of right lower cranial nerves palsy. A small mass was found on the right side at the back of his mouth. light microscopy and histoimmunochemical studies of the biopsy of the mass showed an alveolar soft part sarcoma arising from the right myohyoid muscle. The unusual location and presentation of this rare tumor is discussed.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
6/33. Inferior alveolar nerve paresthesia caused by endodontic pathosis: a case report and review of the literature.Sensory disturbances such as anesthesia, hypoesthesia, hyperesthesia, and paresthesia may be present in the oral cavity, stemming from many local and systemic factors. paresthesia of the inferior alveolar nerve is quite rare because of the unique anatomy of this nerve. Among other effects, periapical lesions can damage the nerve, resulting in paresthesia of its innervated area. Only a few cases of paresthesia caused by these lesions are reported in the literature. In this report we present a case of paresthesia of the right inferior alveolar nerve; discuss the anatomy, pathobiology, and etiology; and suggest that a periapical lesion affecting the lower right second molar (No. 31) may have been the cause. The routine x-rays (intraoral and panorex) and the axial and cross-sectional tomographs of the mandible by means of computed tomography contribute to making this case a good example of nerve injury.- - - - - - - - - - ranking = 6keywords = alveolar (Clic here for more details about this article) |
7/33. Peripheral third cranial nerve enhancement in multiple sclerosis.Cranial nerve III dysfunction in multiple sclerosis (MS) is uncommon. Seven cases of isolated cranial nerve III paresis associated with MS have been reported in the English-language literature. MR imaging was obtained in five cases demonstrating lesions within the midbrain. We present the detailed clinical and MR imaging findings of a young woman with MS and an isolated, painful pupil involving complete left cranial nerve III palsy. Initial MR imaging showed isolated enhancement of the cisternal portion of the cranial nerve III, suggesting that peripheral nervous system involvement may develop as part of the disease process in some patients with MS.- - - - - - - - - - ranking = 0.014107940369076keywords = process (Clic here for more details about this article) |
8/33. infection-related inferior alveolar and mental nerve paresthesia: case reports.Nerve injury can be related to mechanical, chemical, and thermal factors. infection-related paresthesia is usually related to mechanical pressure and ischemia associated with the inflammatory process. Another cause of paresthesia could be the toxic metabolic products of bacteria or inflammatory products released following tissue damage. This article presents cases of inferior alveolar and mental nerve paresthesia caused by an infected impacted tooth, an infected cyst, and periapical infection. The possible pathophysiologic mechanism of nerve injury, therapy, and prognosis for recovery are also discussed.- - - - - - - - - - ranking = 5.0141079403691keywords = alveolar, process (Clic here for more details about this article) |
9/33. Cranial nerve involvement with Lyme borreliosis demonstrated by magnetic resonance imaging.We report a patient with cranial nerve and meningeal symptoms secondary to Lyme borreliosis. MRI using gadolinium contrast material demonstrated this inflammatory process.

10/33. Simultaneous paresthesia of the lingual nerve and inferior alveolar nerve caused by a radicular cyst.The inferior alveolar nerve is sometimes affected by periapical pathoses and mandibular cysts. However, mandibular intraosseous lesions have not been reported to disturb the lingual nerve. A case of simultaneous paresthesia of the right lingual nerve and the right inferior alveolar nerve is presented. The possible mechanisms of this extremely uncommon condition are discussed.- - - - - - - - - - ranking = 6keywords = alveolar (Clic here for more details about this article) |
