Many methods based on biometrics such as fingerprint, face, iris, and retina have been proposed for person identification. However, for deceased individuals, such biometric measurements are not available. In such cases, parts of the human skeleton can be used for identification, such as dental records, thorax, vertebrae, shoulder, and frontal sinus. It has been established in prior investigations that the radiographic pattern of frontal sinus is highly variable and unique for every individual. This has stimulated the proposition of measurements of the frontal sinus pattern, obtained from x-ray films, for skeletal identification. This paper presents a frontal sinus recognition method for human identification based on Image Foresting Transform and shape context. Experimental results (ERR = 5,82%) have shown the effectiveness of the proposed method.

Pós-graduação em Ciência da Computação - IBILCE; Diversos métodos biométricos baseados em características físicas do corpo humano como impressão digital, face, íris e retina têm sido propostos para identificação humana. No entanto, para a identificação post-mortem, tais características biométricas podem não estar disponíveis. Nestes casos, partes do esqueleto do corpo humano podem ser utilizadas para identificação, tais como dentes, tórax, vértebras, ombros e os sinus frontais. Investigações anteriores mostraram, por meio de técnicas manuais para extração de características, que os padrões dos sinus frontais são altamente variáveis entre indivíduos distintos e únicos para cada indivíduo. Esta dissertação de mestrado tem por objetivo propor um método computacional para o reconhecimento de sinus frontais para identificação humana post-mortem em aplicações forenses. Para tanto, foram avaliados métodos de segmentação de imagens de radiografias anteroposteriores de sinus frontais. O método baseado na Transformada Imagem-Floresta demonstrou ser eficiente para segmentação dos sinus frontais das imagens de radiografias, exigindo mínima intervenção humana. Foram também investigadas e implementadas técnicas para extração de descritores geométricos e descritores baseados nas formas dos sinus frontais. Experimentos realizados em um banco de imagens contendo 90 radiografias anteroposteriores de 29 indivíduos mostraram que a técnica de extração de características baseada nos descritores de contexto da forma foi a mais eficaz...

We present a case report of a patient with pneumocranium secondary to halo vest pin penetration and a review of literature. The objectives of this study are to report a rare complication of halo vest pin insertion and to discuss methods of prevention of this complication. Halo vest orthosis is a commonly used and well-tolerated upper cervical spinal stabilizing device. Reports of complications related to pin penetration is rare and from our review, there has been no reports of pneumocranium occurring from insertion of pins following standard anatomical landmarks. A 57-year-old male sustained a type 1 traumatic spondylolisthesis of C2/C3 following a motor vehicle accident. During application of the halo vest, penetration of the left anterior pin through the abnormally enlarged frontal sinus occurred. The patient developed headache, vomiting and CSF rhinorrhoea over his left nostril. He was treated with intravenous Ceftriaxone for 1 week. This resulted in resolution of his symptoms as well as the pneumocranium. In conclusion, complications of halo vest pin penetration are rare and need immediate recognition. Despite the use of anatomical landmarks, pin penetration is still possible due to aberrant anatomy. All patients should have a skull X-ray with a radio-opaque marker done prior to placement of the halo vest pins and halo vest pins have to be inserted by experienced personnel to enable early detection of pin penetration.

Giant mucoceles of the frontal sinus are rare but their recognition is important in the differential diagnosis of proptosis and fronto-orbital lesions. The authors describe a patient with frontal giant mucocele with intracranial as well as orbit and ethmoid sinus involvement. Thirty-two years after a frontal sinus fracture, a 51-year-old female presented with headache, and left exophthalmos and ophthalmoplegia. Computed tomography and magnetic resonance imaging demonstrated a giant frontal sinus mucocele with extension into the left anterior cranial fossa. The mucocele was treated with a transcranial and endoscopic transnasal approach. The frontal sinus was then cranialized with reconstruction of the posterior wall, and finally a wide nasal drainage was performed. The clinical symptoms disappeared immediately after surgery.

Introduction: Frontal sinus mucoceles can present with a multitude of different symptoms including ophthalmic disturbances. Even benign, they have a tendency to expand by eroding the surrounding bony walls that displaces and destroys structures by pressure and bony resorption. Case report: A 32-year-old man with diplopia, proptosis of the right eye and headache was presented. The diagnosis was frontal sinus mucocele with intracranial and intraorbital extension. Possible clinical manifestations of mucoceles, diagnostic imaging techniques and treatment used are discussed. Conclusion: Frontal mucoceles are benign and curable, early recognition and management of them is of paramount importance, because they can cause local, orbital or intracranial complications.
