There has been significant evolution over time from external headlight sinus surgery to endoscopic sinus surgery(ESS). ESS was pioneered by Messenklinger, who discovered that the sinuses had a predetermined mucociliary clearance pattern towards the natural ostium irrespective of additional openings into the sinuses. This philosophy of opening the natural ostium of the diseased sinus was then po...

Changes in imaging sinonasal inflammatory disease have paralleled changes in the treatment of chronic sinusitis. As functional endoscopic sinus surgery has become a more widespread technique, coronal computed tomography (CT) has become the primary imaging modality, replacing plain radiography. Knowledge of the plethora of sinonasal anatomic variations and the inherent surgical implications is c...

The application of image-guided systems to sinus surgery is gaining in popularity. This study tried to evaluate the efficacy of image-guided surgery (IGS) in the fenestration of the sphenoid sinus in patients with chronic rhinosinusitis (CRS) who received revision functional endoscopic sinus surgery (FESS). A total of 51 CRS patients who received revision FESS incorporating IGS between January ...

PURPOSE To evaluate the optimal parameters for the CT examination of patients who are having functional endoscopic sinus surgery. METHODS CT scanning was performed on two fresh cadaveric heads in the direct coronal plane, varying the section thickness, intersection gap, scanner gantry angle, and amperage. The nasal cavity and paranasal sinuses were examined independently in a blinded fashion ...

BACKGROUND For more than 70 years, the coexistence of asthma and paranasal rhinosinusitis has been noted in the medical literature. Causal relationships have been proposed but not proved. To date, limited evidence exists suggesting that asthma improves after surgical correction of rhinosinusitis. OBJECTIVE To determine whether asthma control improved after first-time functional endoscopic sin...

Purpose: Here we report a case of postoperative cheek cyst arising from the maxillary sinus with orbital involvement.Case summary: A 56-year-old male presented to our clinic right periorbital edema and visual impairment. Upon examination, he had field defect best corrected acuity 0.6 in eye. The patient was diagnosed originating sinus. developed because radical surgery. Computed tomography show...

Treatment of frontal sinus using surgery is complicated owing to the complex anatomical structure of the sinus region. The aim of the present study was to investigate the efficacy and safety of Draf IIb endoscopic frontal sinus surgery treatment for frontal sinus lesions using the agger nasi approach on 19 patients (28 left or and right nasal cavities). A 10-12 mm excision of the upper frontal ...

OBJECTIVE To investigate whether functional endoscopic sinus surgery (FESS) for the treatment of chronic rhinosinusitis will induce changes in intraocular pressure (IOP). DESIGN Prospective, nonrandomized, preoperative and postoperative study. SETTING University-affiliated medical center. PATIENTS Thirty patients who underwent FESS for chronic rhinosinusitis with or without polyps were pr...
