In an adult female with sarcoidosis, prior tympanic membrane perforation and scar tissue, and recent upper‑respiratory infection presenting with acute bacterial maxillary sinusitis, right‑sided eustachian tube dysfunction (autophony, crackling, hearing breath and heartbeat), right periorbital pressure headache, and mild leukocytosis with eosinophilia, what is the appropriate diagnostic workup and management plan?

Diagnostic Workup and Management for Acute Bacterial Sinusitis with Eustachian Tube Dysfunction in a Patient with Sarcoidosis

This patient requires immediate antibiotic therapy for acute bacterial sinusitis given the presence of severe symptoms (yellow sputum, maxillary tenderness, new productive cough), combined with specialist consultation for both ENT evaluation of her eustachian tube dysfunction and rheumatology/pulmonology assessment of her sarcoidosis activity, which is likely contributing to her upper airway inflammation.

Immediate Management

Antibiotic Therapy

Start amoxicillin-clavulanate (not amoxicillin alone) as first-line therapy for 10-14 days 1, 2. The addition of clavulanate is critical given:

• Her recent sinus infection (within past month increases resistance risk)
• Leukocytosis (WBC 11.76) suggesting active bacterial infection
• Severe presentation with purulent sputum and maxillary tenderness

Dosing: Standard adult dosing of amoxicillin-clavulanate 875/125 mg twice daily, or high-dose 2000/125 mg twice daily if high local pneumococcal resistance (>10%) 3, 2.

Adjunctive Therapy

• Intranasal corticosteroids as adjunct to antibiotics for acute sinusitis 1
• Saline irrigations for symptomatic relief 1
• Continue ibuprofen for headache management
• Decongestants may provide symptomatic benefit 1

Diagnostic Workup

Immediate Laboratory Assessment

Her labs already reveal concerning findings that require action:

Inflammatory markers:

• ESR elevated at 38 (increased from 20) suggests active inflammation—could represent sarcoidosis flare versus infection 1
• Eosinophilia (1.05) may be reactive to sarcoidosis and upper airway inflammation 1
• Leukocytosis (11.76) supports acute bacterial infection

Metabolic concerns:

• A1C 6.2% (prediabetes range, increased from 5.8)—continue semaglutide but monitor closely
• Elevated AST/ALT (33/39)—may reflect sarcoidosis hepatic involvement or medication effect

Imaging Considerations

Do NOT obtain CT imaging at this time for the acute sinusitis alone, as diagnosis is clinical 4, 2. However, imaging may be warranted if:

• No improvement after 3-5 days of appropriate antibiotics 1
• Concern for complications (orbital involvement, intracranial extension)
• Need to assess sarcoidosis extent given elevated inflammatory markers

Specialist Consultation Required

ENT referral is mandatory given 1:

1. Recurrent sinusitis (recent 2-week episode, now new acute episode)
2. Underlying sarcoidosis complicating assessment
3. Eustachian tube dysfunction with autophony, hearing breath/heartbeat, crackling—these symptoms suggest either dilatory dysfunction or patulous tube 5
4. Prior tympanic membrane perforation with significant scar tissue
5. History of vertigo (resolved but relevant)

Rheumatology/Pulmonology consultation needed for:

• Rising ESR suggesting possible sarcoidosis flare
• Sinonasal sarcoidosis occurs in approximately 5-15% of patients and may require specific treatment 6, 7, 8
• Coordination of systemic corticosteroid therapy if needed

Eustachian Tube Dysfunction Management

The patient's symptoms (autophony, hearing breathing/heartbeat, crackling with swallowing) are classic for eustachian tube dysfunction 5. This is likely secondary to her acute sinusitis and underlying sarcoidosis-related inflammation 9.

Conservative management:

• Nasal decongestants (short-term, <3 days)
• Intranasal corticosteroids (already recommended for sinusitis)
• Valsalva maneuvers
• Treatment of underlying sinusitis should improve eustachian tube function

ENT will assess for:

• Type of dysfunction (dilatory vs. patulous) 5
• Need for tympanometry or other objective testing
• Relationship to sarcoidosis involvement 6

Headache Management

Right Periorbital Headache

This is likely rhinogenic headache from maxillary sinusitis given:

• Location behind right eye
• Temporal relationship to sinus infection
• Associated photophobia
• Improvement with ibuprofen

Management: Should improve with sinusitis treatment. If persistent after infection resolves, consider:

• Migraine evaluation (photophobia, unilateral location suggest possible migraine component)
• Ophthalmology referral to exclude elevated intraocular pressure (though no halos, redness, or vision changes make this less likely)

Occipital Headache

The separate 2-year history of episodic occipital headache awakening her from sleep requires separate neurologic evaluation if not previously worked up, as this pattern can indicate:

• Increased intracranial pressure
• Posterior fossa pathology
• Sleep apnea-related headaches

Critical Pitfalls to Avoid

1. Do not delay antibiotics waiting for imaging—diagnosis is clinical 1, 2
2. Do not use antibiotics alone without intranasal corticosteroids in this patient with underlying inflammatory disease 1
3. Do not attribute all symptoms to sinusitis—her sarcoidosis may be causing sinonasal involvement requiring systemic therapy 7, 8
4. Do not ignore rising inflammatory markers—ESR increase from 20 to 38 may indicate sarcoidosis flare requiring systemic corticosteroids 1
5. Do not overlook the eustachian tube dysfunction—this may persist after sinusitis resolves and require specific ENT management 9, 5

Follow-up Timeline

• 3-5 days: Reassess response to antibiotics; if no improvement, consider alternative antibiotic 1
• 10-14 days: Complete antibiotic course
• 2-4 weeks: ENT evaluation for persistent eustachian tube dysfunction and to assess for sinonasal sarcoidosis 6, 8
• Ongoing: Rheumatology/pulmonology follow-up for sarcoidosis management given rising inflammatory markers

Special Considerations for Sarcoidosis

Sinonasal sarcoidosis presents with 8:

• Nasal obstruction (65.8%)
• Crusting (29.9%)
• Epistaxis (18.4%)
• Endoscopic findings: crusting, mucosal thickening, subcutaneous nodules

If sinonasal sarcoidosis is confirmed, treatment typically requires 7, 8:

• Topical nasal steroids (already recommended)
• Oral corticosteroids (may need prolonged course)
• Saline irrigations
• Surgery reserved for refractory cases (only 10.5% in one series)

The combination of recurrent sinusitis, eosinophilia, and known sarcoidosis raises concern for chronic hyperplastic sinusitis related to her underlying granulomatous disease 1, which may require systemic corticosteroids beyond the acute infection treatment.
