“…Recently, endoscopic surgery has been started to be used for the structures located behind the borders of paranasal sinuses. [6] In cases of epistaxis, challenging operations as internal maxillary artery ligation, repairs of cerebrospinal fluid leakage, orbital decompression and pituitary gland interventions can be performed endoscopically. As has been observed, transnasal interventions decrease morbidity and mortality rates when compared with transcranial procedures.…”

ÖzetAmaç: Sfenoid sinüste yer alan septum, optik sinir ve internal karotid arter ile ilgili olarak varyatif durumlar›n belirlenmesi.Yöntem: Akut/kronik sinüzit tan›s›yla paranasal sinüs bilgisayarl› tomografi istenen 218 hasta retrospektif olarak taranm›flt›r. Bu hastalar›n tomografileri aksiyel ve koronal kesitlerde incelenerek sfenoid sinüs, kemik septa varyasyonlar›, say› ve uzan›m flekli yönünden s›n›f-land›r›lm›fl, ayr›ca optik sinir ve internal karotid arter protrüzyon valanslar› hesaplanm›flt›r.Bulgular: Radyolojik inceleme sonucunda 5 tip septa varyasyonu saptanm›flt›r. Yüz otuz iki adet (%60,5) tek komplet septumlu, 66 adet (%30.2) tek inkomplet septumlu, 6 adet (%2.7) çift septumlu (komplet+inkomplet), 9 adet (%4.1) çift septumlu (komplet+komplet) ve 5 adet (%2.2) septumu olmayan sfenoid sinüs tan›mlanm›flt›r. Tek olan septumlar›n %64 oran›nda orta hatta oldu¤u, di¤er tiplerin ise orta hatt›n hemen sa¤ veya solundan bafllad›¤› izlenmifltir. Ayr›ca optik sinir ve internal karotid arter protruzyon oranlar› (n=39) 17.8% ve (n=61) %27.9 olarak bulunmufltur. Sonuç: Cerrahi öncesi bilgisayarl› tomografi ile yap›lan de¤erlendir-me ve cerrahi planlama, endoskopik giriflimler için çok büyük önem tafl›makta ve olas› majör cerrahi komplikasyonlar›n azalt›lmas›nda rol almaktad›r.Anahtar sözcükler: Endoskopik sinüs cerrahisi, sfenoid sinüs varyasyonlar›. AbstractObjective: To determine septal variations and rates of intrasinusal protrusions of optic nerve and internal carotid artery in sphenoid sinus. Methods:Retrospective analysis of spiral computed tomography scanning of paranasal sinuses of 218 patients diagnosed as acute/chronic sinusitis was performed. Bilateral sphenoid sinuses were evaluated as if a single sinus, septa of this sinus were evaluated in terms of number and configuration. Besides rates of optic nerve and internal carotid artery protrusions were determined.Results: A total of 5 types of septal variations were detected. A single complete septum (n=132; 60.5%), a single incomplete septum (n=66; 30.2%), double septum (complete + incomplete, n=6; 2.7%), two complete septa (n=9; 4.1%), and sphenoid sinuses without septum (n=5; 2.2%) were identified. Sixty-four percent of single septum was located in midline, while other types were found immediately right or left side of the midline. Besides, protrusions of optic nerve and internal carotid artery were detected in 39 (17.8%) and 61 (27.9%) cases, respectively. Conclusion:Preoperative evaluation with computed tomography and surgical planning dependent on these findings are very important for endoscopic interventions and these approaches minimize potential major intraoperative complications.

The aim of this study is to assess the pneumatization of the paranasal sinuses (PNS) and other parts of temporal bone such as mastoid air cells and to investigate if there was any association between the aeration of these structures among the three major ethnic groups in Malaysia (Malay, Chinese, Indian) as this would be representative of Asia. A retrospective review of 150 computed tomography (CT) scans of PNS and temporal bones was done and analysed. The pneumatization of each area was obtained and compared using statistical analysis. Patients with a history of previous medical or surgical problems in the intended areas were excluded from the study. The pneumatization of the mastoid air cells and other temporal bone parts were noted to be symmetrical in more than 75 %. There was a positive correlation between the pneumatization of mastoid air cells and that of the sphenoid sinus. The prevalence of Agger nasi, Haller's and Onodi cells was observed to be significantly higher in the Chinese group. Preoperative assessment of the temporal bone and PNS with CT scan may be helpful in the evaluation of their anatomical landmark and decrease the possibility of surgical complications related to 3D structures.

“…Christmas et al 28 suggested that such great variation might be explained by the different definition criteria or by ethnic differences. 29 In agreement with Driben et al, 25 we believe that the endoscope is an adequate instrument to detect an Onodi cell.…”

2008A Deus, sempre iluminando meus passos, fazendo-me sentir sua presença quando menos espero, mostrando que realmente existe uma força maior que nos guia.Aos meu queridos pais, Bernardo e Augusta, que nunca mediram esforços para me oferecer o melhor. Exemplos de caráter, dignidade, ética, honestidade, educação, amor ao próximo, humildade, mostraram-me o quão importante é ter uma família. Por vocês, tenho saudades da minha infância, orgulho do presente e certeza do futuro!!! Obrigado por tudo, amo vocês!! À minha irmã, Érika, e ao meu cunhado Almir, meu elo com o passado, que sempre vão estar comigo nos momentos alegres e tristes. AgradecimentosAo Prof. Dr. Richard Louis Voegels, meu orientador, por ter despertado meu interesse na área de rinologia. Exemplo de pessoa determinada, competente, coerente e correta. Obrigado por ter acreditado que poderíamos chegar a esta etapa.Ao Prof. Dr. Ricardo Ferreira Bento, Professor Titular da Divisão de Clínica Otorrinolaringológica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP), por me ter dado a oportunidade de aprender e ser treinado neste serviço de otorrinolaringologia de excelência. Exemplo de empreendedorismo e dedicação a esta clínica.Ao Prof. Dr. Aroldo Miniti, Professor Emérito de Otorrinolaringologia do HCFMUSP, por me ter estimulado e mostrado que ensinar não é criar concorrentes e, sim, conquistar amigos, abrindo portas para centenas de jovens médicos de várias regiões do Brasil.Ao Prof. Dr. Ossamu Butugan, minha gratidão pelos ensinamentos na área de rinologia e na relação médico-paciente. Do senhor levarei lições inesquecíveis, sempre ouvir o paciente, ter humildade, ética e levarei sobretudo, a sensação de que sempre haverá algo a aprender.Ao Prof. Dr. Luiz Ubirajara Sennes, pelos ensinamentos de valores éticos tanto na prática médica, quanto na pesquisa científica. Fez-me perceber que é possível conciliar ensino, pesquisa e assistência em todas as áreas da otorrinolaringologia com competência e dinamismo. Introduction: There are extremely important anatomic relationships between the sphenoid sinus (SS) and neurovascular structures. These structures may have several anatomic variations, which makes their relationship with the sphenoid sinus complex and carries risks of severe injuries during surgery. Objective: This prospective study used endoscopic cadaver dissection to describe details of SS anatomic variations and to evaluate agreement between sides and differences between sexes and ethnic groups. Casuistic and Methods: Fourty-five cadavers (90 nasal fossae) of both sexes ageing between 30 and 83 years underwent careful dissection of the sphenoid sinus. Distance from the SS anterior wall to the anterior nasal spine, the position and shape of the SS, the degree of SS pneumatization, the presence of Onodi cells, the dominance between sides, the insertion of the intersinus septum and crests, the presence of dehiscence and protrusions of the internal carotid artery (ICA), optic nerve (ON), maxillary and vidian nerves...
