Parapharyngeal Abscesses Caused by Group G Streptococcus

Area of Science:

• Otolaryngology
• Infectious Diseases
• Surgical Innovation

Background:

• Deep neck abscesses are severe infections potentially causing airway compromise.
• Group A Streptococcus is the most common pathogen, while Group G Streptococcus (GGS) is typically a commensal.
• GGS can rarely cause pharyngeal and peritonsillar infections.

Observation:

• A 56-year-old woman presented with a parapharyngeal abscess, sore throat, and neck swelling.
• The abscess led to upper airway occlusion, necessitating an urgent tracheostomy.
• Diagnosis was confirmed, and treatment involved endoscopic incision and drainage.

Findings:

• Group G Streptococcus was identified as the causative agent of the parapharyngeal abscess.
• The patient underwent successful endoscopic incision and drainage using a rigid curved laryngoscope.
• The specialized laryngoscope provided adequate visualization and working space for the procedure.

Implications:

• This case expands the known spectrum of GGS infections to include parapharyngeal abscesses.
• Endoscopic management with a rigid curved laryngoscope is a viable and effective treatment option.
• Highlights the importance of considering less common pathogens in deep neck space infections.
