The importance of preoperative nasal endoscopy in patients with sinonasal disease.
Functional endoscopic sinus surgery (FESS) has popularized the use of telescopes in sinus surgery and has emphasized the importance of nasal endoscopy and computed tomography (CT) in the evaluation of patients with diseases of the nose and paranasal sinuses. Variations in intranasal and sinus anatomy have been implicated in the etiology of chronic and recurrent sinusitis, and CT imaging has become an important diagnostic tool. Despite this, some patients present with symptoms and telescopic examination suggestive of sinonasal disease, yet demonstrate little abnormality on CT scan. The authors reviewed videoendoscopic and CT examinations of 100 consecutive patients with symptoms of sinus disease and found 9% of patients with abnormal telescopic examination in the context of negative CT findings. In those patients whose CT examinations were positive, telescopic nasal endoscopy was especially useful in delineating the type of soft tissue which obscured the area of the middle meatus. In those patients whose CT examinations were negative, telescopic examination demonstrated septal deflections, mucosal edema involving the middle meatus, as well as turbinate and adenoid hypertrophy. These findings demonstrate that telescopic nasal examination is an important diagnostic modality which often yields important information when evaluating patients with sinonasal disease.
