Types of infection
Fungal
1) Aspergillosis
• A. fumigatus, A. niger, A. flavus
• Granulomatous inflammation of the sinuses which may involve the orbit and intracranial extensions.

Management of acute infections
2) Mucormycosis
•Rhino-orbital-cerebral & pulmonary infections are the most common form.
•Survival rate : 36-50%

Management of acute infections
Fungal
Management of acute infections
Viral
• HSV, EBV, VZV, CMV, Paramyxovirus, Coxsackie virus, Picorna virus
• Mostly symptomatic management, with the exception of Herpes zoster (Shingles)
Management of acute infections
Viral
• 15-35% of HZ patients has postherpetic neuralgia (PHN)
• Early antiviral therapy has been found to reduce the risk and duration of PHN in elderly patients.#

• Dental infection is the most common cause of deep neck abscess.*

Management of acute infections
Signs of Infection
• Local
– Redness, pain, swelling, heat, +/- pus (abscess)
– Loss of function
• Systemic
– Temperature > 37°C (or spikes), malaise, pallor, irritability, fatigue, dehydration
– lymphadenopathy
– Severe signs : dysphagia (sublingual,submandibular), drooling, dysphonia, stridor (airway compromise),trismus

Management of acute infections
Bacterial
• Erysipelas
Cellulitis of the skin with lymphatic involvement
Mainly involves leg but often occurs on the face
Strep. Pyogenes & S. aureus main pathogen

Management of acute infections
Bacterial
• Erysipelas
Area of erythema and swelling has sharp demarcation
Treatment : Augmentin or Penicillin + Clindamycin

• Management
1) Assess for potential airway compromise
2) Administration of broad spectrum antibiotics
3) Investigations
4) Remove source of infection and establish surgical drainage

Warning Signs
• Rapid onset.• Progressive trismus.• Painful trismus that is out of keeping with
with the clinical picture should raise your suspicion regarding a submasseteric/pterygoid space infection.

Reasons for Admission
• Rapidly progressing infection• Difficulty breathing• Difficulty Swallowing• Fascial space involvement• Elevated temperature - >38 • Severe jaw trismus < 10mm• Toxic appearance• Compromised host defences 33
34
Investigations
• Bloods inc glucose and CRP.• Consider blood cultures if appropiate• If pus, send swab and pus for gram stain• Radiological investigations, but these
shoudl not defer treatment.
• WARN THE ANAESTHETIST EARLY

Access
• Submandibular/sublingual space• Parapharyngeal• Buccal• Submassteric

5) Close evaluation in the immediate post-op phase
Management of acute infections
Bacterial
• Recurrent deep neck infections
Consider congenital abnormalities
Proper imaging aids in diagnosis
Most common cause :
Branchial cleft cyst
Lymphangioma, thyroglossal duct cyst
Ref : Nusbaum AO et al, Recurrence of a deep neck infection: a clinical indication of an underlying congenital lesion. Arch Otolaryngol Head Neck Surg 125 (12) : 1379-82 1999 Dec

Salivary Gland Infections
• Salivary Gland Infections:
Bacterial ascending infections especially with xerostomia, in the presence of salivary calculi. Painful, swelling in F.O.M or as an acute pre-auricular swelling.
Treatment involves giving patient fluids to increase saliva flow, antibiotics and +/- drainage depending on the presence of a collection.
Amoxycillin + metronidazole + flucloxacillin (staph)
Think of and exclude viral infection eg mumps – most often bilateral parotid swellings 39

Ludwigs Angina
• (Spreading Cellulitis in the FOM)
• Potentially life threatening, a cellulitis starting in the floor of the mouth and often arising from a mandibular molar
Bilateral submandibular and sublingual space infection
Clinical signs:
Oedema on both sides of the floor of the mouth
Raised tongue
Bilateral submandibular space involvement
Oedema spreading down the neck – often with loss of definition of anatomical structures
Progressive trismus, pain, dysphagia, dysphonia
¤ For hospital admission

Complications
• Trismus (Classically sub masseteric space/lateral pharyngeal space infections)
• Extra-oral incisions – CNVII marginal mandibular branch, scarring, drains and ascending infection
