Indications
1.History. . . one or more required

a. Failure of medical management for chronic sinus pathology
(The history must include specific symptoms and findings obtained by the otolaryngologist. A historical diagnosis labeled "sinusitis"
by the patient or unsubstantiated symptoms alone is not sufficient documentation to establish this as a chronic illness).

SINUS SIGNS AND SYMPTOMS
Major Factors Minor Factors
Facial pain/pressure*
Facial congestion/fullness
Nasal obstruction/blockage
Nasal discharge/purulence/discolored post nasal drainage
Hyposmia/amosmia
Purulence in the nasal cavity on examination
Fever (acute rhinosinusitis only)**
Headache
Fever (all non-acute)
Halitosis
Fatigue
Dental pain
Cough
Ear pain/pressure/fullness

* Facial pain/pressure alone does not constitute a suggestive history for rhinosinusitis in the absence of another major nasal symptom or sign. 

** Fever in acute sinusitis alone does not constitute a strongly suggestive history for acute sinusitis in the absence of another major nasal symptom or sign.

  • Chronic disease is defined as sinusitis of greater than 12 weeks duration that includes either two or more major sinus symptoms, or includes at least one major and two minor sinus symptoms 
  • Clinically significant recurrent sinusitis is defined as 4 or more episodes of acute sinusitis per year, each lasting greater than 7 - 10 days, and there is absence of symptoms between episodes (without antibiotic therapy) 
b. Complications of sinusitis, including extension to adjacent structures
c. Multiple or recurrent polyps with airway obstruction
d. Mucocoele
e. Chronic anterior headache, caused by anatomic or pathologic sinus disorder
f. Impaired sense of smell
g. Inverted papilloma or localized malignancy
h. CSF leak
i. Dacryocystorhinostomy
j. Orbital decompression
k. Repair of choanal atresia and nasal lacrimal duct obstruction 

2. Physical Examination

a. Complete anterior and posterior nasal examination (rhinoscopy after mucosal decongestion)
b. Examination of nasopharynx (if possible)
c. Nasal endoscopic examination, obtained following medical therapy

3. Tests

a. For surgical planning, coronal CT scan is required in all cases following medical therapy.
b. Complete axial CT scan... required in cases with complex disease.
c. Culture and sensitivity - optional.
d. Allergy testing.

4. Optimal Medical Therapy: prior to obtaining sinus CT scan, prior to nasal endoscopy, and prior to surgery

a. Allergic evaluation and treatment when indicated
b. Decongestants when indicated
c. Topical and/or systemic steroids when indicated
d. Treatment of rhinitis medicamentosa, when present
e. Education on environmental irritants including tobacco smoke
f. Antibiotic therapy consisting of four to six consecutive weeks of appropriate antibiotic drugs 

5. Surgical Procedure and Findings:

a. Must be compatible with clinical status, CT findings, and nasal endoscopic findings. That is, only patients with significant persistent sinus symptoms and pathology should undergo surgery.

Post-Operative Observations

1. Bleeding, eyelid ecchymosis; notify surgeon
2. Pain - severe headache; notify surgeon
3. Packing - was middle meatal packing sufficient? Is it in desired location?
4. Vision - if there is loss or double vision, notify surgeon immediately
5. Swelling - is there evidence of facial edema? If hematoma, notify surgeon
6. Mental status - is patient alert and oriented? If not, notify surgeon 

Outcome Review
1. One Week

a. Healing - Did patient require treatment for bleeding or infection? Is surgical site healing satisfactorily?
b. Did patient require one or more episodes of debridement?
c. Pathology - Does the pathology report indicate need for further treatment and if so, how managed?
d. Are there any indications for CSF leak rhinorrhea? 
2. Beyond One Month
a. Presenting problem - are persisting sinus symptoms improved?
b. Airway - Is there evidence of airway obstruction due to polyps or nasal crusting?
c. Are there any indicators for CSF rhinorrhea?

Patient Information

Endoscopic sinus surgery is performed through an intra nasally and is recommended only after it has been determined that medical management has been unsuccessful. Surgery, medical management, and failure to intervene all have risks, including as a group, postoperative bleeding, orbital complications (visual impairment), intracranial extension (brain damage or infection), leakage of cerebrospinal fluid, persistent or recurrent nasal obstruction due to failure to manage polyps and recurrent nasal or sinus infections.

Radiographs and endoscopic findings considered in conjunction with the patients clinical status - following medical evaluation and therapy - will identify the appropriate sinuses to treat.

Important Notice

The Clinical Indicators for Otolaryngology--Head and Neck Surgery are guidelines only. In no sense do they represent a standard of care. The applicability of an indicator for a procedure, and/or of the process or outcome criteria, must be determined by the responsible physician in light of all the circumstances presented by the individual patient. Adherence to these guidelines will not ensure successful treatment in every situation. The American Academy of Otolaryngology-Head and Neck Surgery, Inc. emphasizes that these clinical indicators should not be deemed inclusive of all proper treatment decisions or methods of care, nor exclusive of other treatment decisions or methods of care reasonably directed to obtaining the same results.
