Oropharyngeal, Salivary Gland and Upper Aerodigestive Disorders
Connect the major disease patterns, clinical clues, investigations and management principles for rapid KMU-focused revision.
1. THE TOPIC IN ONE CONNECTED FLOW
Disorders in this region can be understood by first identifying the dominant pattern: mucosal ulceration, tonsillopharyngeal inflammation, salivary-gland inflammation or obstruction, or a persistent mass. The clinical pattern then guides the investigation and determines whether treatment is supportive, anti-inflammatory, antimicrobial, procedural or oncological.
Inflammation • congenital defect • obstruction • neoplasia
Mucosal injury • infection • salivary stasis • abnormal cell growth
Ulcer • tonsillar swelling • blocked duct • gland mass
Oral pain • sore throat • meal-related swelling • persistent lump
Examination • microbiology • ultrasound/imaging • biopsy
Supportive care • medical therapy • drainage/removal • cancer treatment
Healing • abscess • recurrent disease • local or nodal spread

2. KEY CLINICAL CONNECTIONS
Acute tonsillitis → spread into peritonsillar tissue → localized pus → unilateral bulging + severe pain → trismus and muffled voice → drainage when an abscess is established.
Duct stone → impaired drainage → increased pressure during meals → pain and swelling → salivary stasis → secondary bacterial sialadenitis if infection develops.
Pleomorphic adenoma → mixed epithelial/myoepithelial pattern; Warthin tumor → oncocytic epithelium + lymphoid stroma; adenoid cystic carcinoma → perineural invasion → pain.
Persistent unilateral lesion or dysphagia → careful oral/oropharyngeal and neck examination → endoscopic assessment + biopsy → imaging for local and cervical nodal extent.
