The nasolabial cyst is an uncommon non-odontogenic cyst that develops in the lower region of the nasal ala; its pathogenesis is uncertain. This lesion grows slowly and measures between 1.5 and 3 cm; it is characterized clinically by a floating tumefaction in the nasolabial sulcus, which elevates the upper lip. The diagnosis is based on the clinical findings and, if necessary, image exams. This paper reports a case of a white 48-year-old Brazilian female patient that presented a firm tumor in the left ala of the nose; the clinical features suggested a nasolabial cyst. CT scans revealed an expanding tumor with soft tissue density located in the left ala of the nose. It measured 1.2 cm in diameter and had a clear and well-defined outline; its homogeneous density was about 50 HU. MR images revealed a circular lesion located in soft tissue; T1 and T2 weighted signals were hyperintense, as were images after fat suppression. The diagnosis was a nasolabial cyst, which was confirmed by histopathology after surgery.
Objective. Assess headache and bruxism in Craniomandibular Disorders (CMDs) and non CMDs patients. Method. Clinical examination, questionnaires, headache criteria, severity of bruxism. Results. The prevalence of headache was 68.3% in the CMDs group and 51.4% in the non-CMDs group (p<0.04).Tension type (TTH)=52.8% and combination headaches=25.2% predominated in CMDs. Migraine was more prevalent in Non-CMDs (21.1%) than in CMDs subjects (11.4%). Severe bruxism predominated in the headache/CMDs group=35% as compared to the non-headache/ CMDs group=21%, (p=0.08). We found a frequency of 29.3% extreme bruxism in the headache group and 7% in the non-headache group (p><0.0005). The frequencies of mild/moderate bruxism were about 28% in the TTH, 44.8% in the “other headaches” and 72% in the non-headache/CMDs groups. The frequencies of severe/extreme bruxism were 72.3% in the TTH, 55.2% in the “Other headaches”, and 28% in the non- headache/CMDs groups(p=0.0001). Conclusion. Headache, TTH and combination headache were common in the CMDs group. Severe and extreme bruxism were more prevalent in the headache /CMDs group than in the “other headaches” and in the non/headache CMDs groups. Severe and extreme bruxism were more frequent in the TTH/CMDs group.>
O cisto nasolabial é um cisto não odontogênico raro que se desenvolve na região inferior da asa nasal, com patogênese ainda incerta. Esta lesão, que possui crescimento lento e dimensões variáveis (1,5-3cm), caracteriza-se clinicamente por uma tumefação flutuante na região do sulco nasolabial ao redor da asa do nariz, causando uma elevação do lábio superior. Seu diagnóstico pode ser feito basicamente pelo quadro clínico e, se necessário, complementando-se com exames auxiliares por imagens. O presente trabalho relata o caso de uma paciente do sexo feminino de 48 anos, que se queixava da presença de uma massa consistente na região da asa esquerda do nariz e cujas características clínicas eram compatíveis com cisto nasolabial. As imagens de TC demonstraram uma formação expansiva com densidade de tecido mole, localizadas na região nasal esquerda medindo cerca de 1,2cm de diâmetro e apresentando contornos nítidos e bem definidos e densidade homogenia ao redor de 50 UH. Já as imagens de RM mostraram uma lesão de aspecto circular localizada em tecido mole, apresentando hiperintensidade nas imagens ponderadas em T1, T2 e no recurso de supressão da gordura, sendo a hipótese diagnóstico de cisto nasolabial, confirmado pelo exame histopatológico depois da cirurgia.
