What is PEDIATRIC RHINOSINUSITIS and How to deal with it?
by Dr. Sharad ENT All about Health and ENTPediatric RS is a multifactorial disease, and the importance of the predisposing factors changes with increasing age.
Depending on the course of the disease, it is divided into acute (10 days to < 3 weeks), subacute (3 weeks to < 12 weeks), and chronic (> 12 weeks). In recurrent disease, complete resolution occurs between the episodes, which are 3 or more in 6 months or more than 4 in 1 year.
Pathophysiology
1. Obstruction in the drainage pathways of the sinuses results in stasis of secretions that leads to sinus disease. The obstruction may be anatomic, physiologic, or both.
2. The anatomic obstruction can be due to turbinate (hypertrophic or enlarged, concha bullosa or pneumatized and paradoxical bend), septum (deviation and spur), polyps, enlarged adenoids and mucosal inflammation from allergy, infection, and irritation.
3. Other conditions which may increase the incidence of sinus disease includes allergy, GERD, air pollution, first- or second-hand smoke, and a daycare environment.
Clinical Features
- Acute rhinosinusitis: It is often preceded by viral upper respiratory infection (URI) with clear nasal discharge, which often recedes within 5 days. If the symptoms of purulent discharge, facial pain, nasal obstruction, and daytime cough persist longer than 10 days, a diagnosis of acute sinusitis should be considered. The features of severe infection include high fever (> 40°C) and periorbital edema.
- Chronic sinusitis: Clinical features include nighttime cough, nasal discharge and obstruction, and postnasal drip. Headache wax and wane symptoms persist for more than 12 weeks. Other features include facial pain, ocular or dental pain, sore throat, low-grade fever, and asthma.
Differential Diagnosis
- Allergic rhinitis
- Recalcitrant rhinosinusitis: Consider and evaluate for immunodeficiency, cystic fibrosis, ciliary immotility disorders, and GERD.
Diagnosis
1. Clinical.
2. Nasal endoscopic examination.
3. Culture of sinus secretions.
4. Allergic assessment: Skin prick test, nasal smear, RAST, and trial of treatment.
5. CT scan (Limited coronal cuts) PNS: Though the gold standard for evaluating sinonasal disease, CT is not necessary to confirm the diagnosis of rhinosinusitis in children. It is indicated only when sinus surgery is considered.
Treatment
1. Medical therapy: It is the initial treatment modality.
Antibiotics, which are indicated in following children, allow for earlier resolution and may prevent complications.
– Severe acute RS
– Acute RS with the protracted course.
– Suspected or proven suppurative complications
a. Acute rhinosinusitis: Antibiotics for 10–14 days; prolonged to 1 month when symptoms do not resolve completely.
– First line antibiotic: Amoxicillin at the normal or high dose.
– First line alternatives (Children allergic to penicillin): Cefdinir, cefuroxime, cefpodoxime, azithromycin (for 3 days) or clarithromycin.
– Second line antibiotics (unresponsive, more severe disease or resistant S. pneumoniae): High-dose amoxicillin/clavulanate (90 mg/kg amoxicillin).
– Children with vomiting: Parenteral ceftriaxone.
b. Chronic rhinosinusitis:
– Beta lactam stable antibiotic for 3 weeks
– Topical nasal sprays:
- Mometasone furoate for children: 2 years
- Fluticasone propionate for children: 4 years
- Other topical nasal steroids for children: 6 years
– Antihistamines: Newer nonsedating
– Mucolytics: Guaifenesin
2. Surgical treatment: It is rarely needed except in cases of orbital or intracranial complications.
a. Adenoidectomy: In the presence of adenoid hypertrophy in cases of CRS.
b. Functional endoscopic sinus surgery: Controversial in pediatric rhinosinusitis.
