The Evaluation of Clinical Signs and Symptoms of Malignant Tumors Involving the Maxillary Sinus: Recommendation of an Examination Sieve and Risk Alarm Score.

This observational study was conducted to evaluate the clinical signs and symptoms of maxillary sinus tumors and to propose a clinical examination sieve and a unique risk alarm score to be used for timely patient referral and vigilance. The study consisted of 70 patients between 20 to 82 years of age from both sexes. The clinical information gained was collected from the upper dentoalveolar segment, orbit, and nasal sites. Regarding the early clinical sign and symptoms of patients, nasal obstruction was found in 67 patients (95.7%), facial swelling in 69 patients (98.6%), paresthesia in 41 patients (58.6%), and epistaxis in 50 patients (71.4%). Furthermore, in terms of the late signs and symptoms, a palpable mass in buccal sulcus was observed in 65 (92.9%) of the patients, lymphadenopathy in 24 (34.3%), paresthesia in 38 (54.3%), and diplopia in 22 (31.4%). Furthermore, general sign and symptoms like exophthalmos was present in 35 patients (50%), anosmia was observed in 37 patients (52.9%), and oroantral fistula was noted in 37 patients (55.9%). Additionally, 67 (95.7%) of the patients complained of nasal obstruction. Similarly, facial asymmetry was observed in 69 (98.6%) of the patients and double vision was observed in 24 (34.4%). Tumors of the maxillary sinus have a very insidious course of spread and uncertain clinical signs and symptoms. What makes diagnosis worse is the fact that the symptoms of these tumors are so well hidden in the sponge-like nature of the midfacial region that they are easily misinterpreted by patients. Therefore, diagnoses must be made early, dentists must be vigilant, and patients must be fully investigated at the slightest suspicion of a tumor, albeit benign.

Basilar artery dolichoectasia an unusual and rare cause of secondary trigeminal neuralgia: a clinical report / Dolicoectasia da artéria basilar uma causa incomum e rara de neuralgia do trigêmeo secundária: um relato clínico

Objective: Patients with Trigeminal Neuralgia often consults a dentist for relief of their symptoms as the pain seems to be arising from teeth and allied oral structures. Basilar artery Dolichoectasia is an unusual and very rare cause of secondary Trigeminal Neuralgia as it compresses the Trigeminal nerve Root Entry Zone. Case reports: We report three cases of Trigeminal Neuralgia caused by Basilar artery Dolichoectasia compression. The corneal reflex was found absent in all three of the cases along with mild neurological deficits in one case. Multiplanar T1/T2W images through the brain disclosed an aberrant, cirsoid (S-shaped) and torturous Dolichoectasia of basilar artery offending the Trigeminal nerve Root Entry Zone. Discussion:Based on these findings we propose a protocol for general dentist for diagnosis of patients with trigeminal neuralgia and timely exclusion of secondary intracranial causes. Conclusion: General dentists and oral surgeons ought to consider this diagnosis in patients presenting with chronic facial pain especially pain mimicking neuralgia with loss of corneal reflex or other neurosensory deficit on the face along with nighttime pain episodes. Timely and accurate diagnosis and prompt referral to a concerned specialist can have an enormous impact on patient survival rate in such cases (AU)

Objetivo: Pacientes com Neuralgia do Trigêmeo frequentemente consultam um dentista para alívio de seus sintomas visto que a dor parece surgir dos dentes e estruturas orais relacionadas. A Dolicoectasia da artéria basilar é uma causa incomum e muito rara de Neuralgia do Trigêmeo secundária, pois comprime a zona de entrada da raiz do nervo trigêmeo. Relatos de casos: Relatamos três casos de Neuralgia do Trigêmeo causada por compressão por Dolicoectasia da artéria basilar. O reflexo da córnea se encontrava ausente em todos os três casos, juntamente com leves déficits neurológicos em um caso. Imagens multiplanares T1/T2W através do cérebro revelaram uma Dolicoectasia cirsóide (em forma de S) anômala e tortuosa da artéria basilar que atingiu a zona de entrada da raiz do nervo trigêmeo. Discussão: Com base nesses achados, propomos para o dentista clínico-geral um protocolo para diagnóstico de pacientes com Neuralgia do Trigêmeo e exclusão oportuna de causas intracranianas secundárias. Conclusão: Os dentistas clínicos-gerais e cirurgiões orais devem considerar este diagnóstico em pacientes que apresentam dor facial crônica, especialmente dor que mimetiza neuralgia com perda do reflexo da córnea ou outro déficit neurossensorial na face junto com episódios de dor noturna. O diagnóstico oportuno e preciso e o encaminhamento imediato a um especialista em questão podem ter um enorme impacto na taxa de sobrevida do paciente em tais casos (AU)

Oral Manifestations of Osteopetrosis.

Osteopetrosis is a hereditary disorder of bone characterized by sclerosis of bone and decreased marrow spaces. Due to depressed marrow function, this disorder can cause anemia, hepatosplenomegaly, recurrent infections and osteomyelitis of jaw. Excessive bone deposition in skull base leads to narrowing of foramina and cranial nerve compression. Bone marrow transplantation is the only curative treatment. Other treatments, like interferon gamma, corticosteroids, parathormone and erythropoietin are also used for management. Transfusion of blood, debridement of wound and antibiotics is used to manage complications. Due to its rarity, it is always difficult to diagnose osteopetrosis. Proper diagnosis and treatment decreases the long-term sequelae of the disease.

Ophthalmic injuries in orbito-zygomatic fractures.

OBJECTIVE: To assess the frequency and severity of ophthalmic injuries in patients with orbito-zygomatic fractures. STUDY DESIGN: A case series. PLACE AND DURATION OF STUDY: Oral and Maxillofacial Department, KEMU/Mayo Hospital Lahore, from January 2009 to December 2011. METHODOLOGY: Patients with orbito-zygomatic fractures were divided into three groups. Group-1 patients had fracture of floor/medial wall of the orbit (orbital-blow out fracture). Group-2 had comminuted orbito-zygomatic fractures. Group-3 had simple zygomatic bone fractures. Frequency and types of ocular injuries were determined on each group. RESULTS: There were 296 (260 male, 36 female) patients with mean age of 31.7 years. Group-1 (n = 20) had 28 ocular findings in 12 (60%) patients including diplopia (n = 10, 36%), enophthalmos (n = 6, 14%), and hyphema, vitreous hemorrhage, retinal hemorrhage, choroidal rupture, traumatic mydriasis, and commotio retinae in 2 cases, 7% each. In Group-2 (n = 106), 44 ocular findings were identified in 30 (28%) patients including diplopia (n = 10, 23%), enophthalmos (n = 4, 9%), commotio retinae (n = 10, 23%), reduced visual acuity (n = 6, 14%), retinal hemorrhage (n = 4, 9%) and corneal laceration, corneal abrasion, retinal detachment, traumatic mydriasis, and canthal laceration in 2 cases, 4.5%. In Group-3 (n = 170), 22 ocular findings were seen in 16 (9%) patients included diplopia (n = 10, 45%), enophthalmos (n = 4, 18%), and retinal tear, hyphema, angle recession, and traumatic mydriasis in 2 cases, (9%) each. CONCLUSION: Ophthalmic injuries are a common complication of orbitozygomatic fractures occurring in about 20% of patients in this study, most frequent in the orbital blow fractures subgroup. Ophthalmology consultation is recommended for patients presenting with midface fractures.
