Use of cone beam computed tomography in otolaryngologic treatments

Abstract

Cone beam computed tomography (CBCT) allows us to evaluate 3-dimensional (3D) morphology of the maxillofacial skeleton and also used in dentomaxillofacial imaging to solve complex diagnostic and treatment planning problems such as craniofacial fractures, temporamandibular dysfunctions or sinus imaging. CBCT uses a rectangular or round 2D detector, which allows a single rotation of the gantry to generate a scan of the entire region of interest. Technological and application-specific factors such as development of compact, relatively low-cost, high-quality, large, flat-panel detector arrays; the availability of low-cost computers with processing power sufficient for cone beam image reconstruction; the fabrication of highly efficient radiograph tubes capable of multiple exposures necessary for cone beam scanning at prices lower than those currently used for fan beam CT; and limited volume scanning (e.g., head and neck) eliminating the need for subsecond gantry rotation speeds make this possible. The objective of this study is to review published evidence for CBCT having an important role in ORL treatments. We aimed to review all the available literature about the CBCT imagination in ORL treatments. Systematic literature search was performed using PubMed and Ovid. Additional literature was retrieved from reference lists in the articles. Systematic analysis of the literature from 1998 to 2010 was performed. A total of 40 abstracts were evaluated independently by two members of the project group, and 38 articles were included in the review.

Cone‐beam computed tomographic analysis of sinus membrane thickness, ostium patency, and residual ridge heights in the posterior maxilla: implications for sinus floor elevation

“…; Cakli et al. ). In implant dentistry, recent guidelines recommend the use of CBCT for three‐dimensional treatment planning, especially prior to SFE – for evaluating both residual alveolar and sinus conditions (Benavides et al.…”

Diagnostic Accuracy of Cone-Beam Computed Tomography in the Evaluation of Chronic Rhinosinusitis

“…After these primary applications, CBCT has gained popularity and is now increasingly being used for the diagnostic imaging of the head and neck region and the ear, nose, and throat area [13,14,15]. CBCT is a useful modality for detecting mucosal thickness, nasal septum deviation, conchal hypertrophy, bullous concha, and retention cysts in these areas [16].…”

Sinusite odontogênica: uma revisão de literatura

“…[18][19][20][21][22] No entanto, estes estudos, avaliaram TCFC de pacientes em bancos de dados, que realizaram os exames por diferentes fins, como distúrbios do desenvolvimento, suspeitas de fratura radicular, trauma e planejamento para implantes [18][19][20][25][26][27] e não exames de pacientes diagnosticados com sinusite maxilar.…”

“…25 Atualmente, a TCFC tem sido amplamente utilizada por cirurgiões-dentistas para avaliar os seios paranasais. 26,27 A TCFC oferece uma baixa dose de radiação quando comparada a tomografia médica, menor tempo de aquisição e melhor resolução da imagem, 28 permitindo ao clínico avaliar a relação entre alterações e/ou infecções dentárias com defeitos no assoalho do seio e qualquer alteração presente nos seios maxilares, em múltiplos planos.…”
