I. Kennedy staging, 1992 Stage 0: normal Stage 1: anatomic variation, unilateral sinus lesion, bilateral lesion confined to the septal sinus Stage 2: bilateral septal sinus lesion with involvement of one subordinate sinus Wang Bing, Department of Otolaryngology, Ning Yang County First People’s Hospital Stage 3: bilateral septal sinus lesion with involvement of two or more subordinate sinuses per side Stage 4: diffuse sinus polyp lesion II. Friedman Staging, 1994 Stage 1: single confined sinus lesion confirmed on CT scan, unilateral or bilateral Stage 2: discontinuous lesion on CT scan, responsive to drug therapy Stage 3: continuous lesion in the septal sinus with or without other sinus turbidity, responsive to drug therapy Stage 4: continuous hyperplastic lesion involving the entire sinus, unresponsive or minimally responsive to drug therapy III. Gliklich Stage 0: normal Stage 1: unilateral sinus lesion or anatomic variation Stage 2: bilateral sinus lesion limited to the septal or maxillary sinuses Stage 3: bilateral sinus lesion with at least pterygoid or frontal sinus involvement Stage 4: total sinusitis Stage 4: Levine’s nasal polyp staging, 1990 Stage 1: nasal polyp confined to the middle nasal tract Stage 2: nasal polyp reaching forward to the anterior part of the middle nasal tract and down to the inferior turbinates, but not obscuring the inferior turbinates Stage 3: nasal polyps were outside the anterior middle turbinate and extended to the medial and posterior middle turbinates Stage 4: nasal polyps extended to the base of the nose, but part of the turbinates could be seen Stage 5: nasal polyps filled the nasal cavity and the turbinates could not be seen V. Lund-Machay Staging System, 1997 (I) Staging System Department Left Right Maxillary sinus Anterior septal sinus Posterior septal sinus Frontal sinus Total score per side Method: 0 for no abnormality, 1 for partial turbidity, 2 for total turbidity; 0 for normal sinuses, 24 for total sinus turbidity (b) Patient’s surgical status score Surgical procedure Left Right Crotchotomy Maxillary sinus ostomy in the middle nasal tract Anterior group septal sinus excision Posterior group septal sinus excision Pterygoid sinus excision Frontal crypt surgery Middle turbinate surgery Total score per side Method: 0 for no operation, 1 for operated ( (III) Patient symptom score Symptoms Pre-operative 3 months 6 months 1 year 2 years Nasal congestion Headache Facial pain Olfactory disturbance Nasal runny nose Sneezing Systemic symptoms Total score Scoring method: 0 for no symptoms, 0 to 10 for degree of symptoms, 10 for most severe symptoms (IV) Scoring of what is seen by nasal endoscopy Signs Baseline 3 months 6 months 1 year 2 years Polyps (left) Polyps (right) Edema (left) Edema (right) (right) Scar (left) Scar (right) Crust (left) Crust (right) Total score Scoring method: polyp: 0 for none, 1 for middle nasal tract only, 2 for beyond middle nasal tract Edema: 0 for none, 1 for mild, 2 for severe Runny nose: 0 for none, 1 for clear, 2 for thick Scar and crust: 0 for none, 1 for mild, 2 for severe
