2024年6月19日 · Functional endoscopic sinus surgery (FESS) is a type of paranasal sinus surgery performed intranasally using a rigid endoscope. Its primary objective is to restore physiological ventilation and mucociliary transport 1.

2012年11月23日 · The aim of functional endoscopic sinus surgery (FESS) to improve mucociliary clearance of the sinuses by removing diseased mucosa and bone that obstruct the sinus outflow tracts. During CT in preparation for FESS, the radiologist looks for anatomic variants, which can predispose the patient to recurrent disease and affect operative technique ...

2022年1月3日 · Functional endoscopic sinonasal surgery (FESS) is the preferred method for treating medically refractive sinusitis. Advances in FESS techniques have expanded the role of FESS surgery in managing benign and malignant masses, as well as becoming the preferred approach in providing access for skull base and pituitary surgeries.

2016年9月19日 · These critical variants and landmarks can be quickly recalled and incorporated into the preoperative imaging report through the use of the mnemonic “CLOSE”: Cribriform …

2021年5月18日 · Radiological imaging plays an important role in the evaluation of patients after endoscopic sinus surgery. Thus, it is important to be familiar with the expected and complicated imaging findings associated with endoscopic sinus surgery, which are reviewed in this article.

2017年5月14日 · FESS is a generally systematic approach to the anterior and posterior aspects of the sinonasal fields and related parts of the nasal cavity, orbit, and anterior and central skull base. The logic and approach of each operation should guide the thinking of those interpreting both diagnostic and preoperative planning studies.

During CT in preparation for FESS, the radiologist looks for anatomic variants, which can predispose the patient to recurrent disease and affect operative technique, and for critical variants, which make surgery haz-ardous. We present a systematic approach to the use of coronal, axial, and sagittal images in CT evaluations before FESS (Fig. 1).

The radiological appearance of the conventional sinusoidal anatomy, anatomical variations and post-FESS appearances will be discussed. Imaging provides an essential roadmap for surgical planning and the morphologic detail provided is essential in recurrent disease.

The reference standard for preoperative imaging in functional endoscopic sinus surgery (FESS) is multiplanar high-resolution computed tomography (HRCT). Surgeons require a precise preoperative anatomical road map, and hence it is essential for radiologists to be familiar with the normal three-dimens …

endoscopic sinus surgery (FESS), the surgical objectives and techniques, patient expectations and the risks of surgery. In part two, the authors will discuss how to make FESS easier, review the imaging pre and intraoperatively, optimise the operative field, decide the extent of surgery, and manage any complications.
