Otitis Diagnosis and Treatment Skills Course

Lesson 1 • Tympanic Membrane Anatomy

Examines TM layers, landmarks, and light reflex. Provides the visual reference framework needed for otoscopic interpretation.

Lesson 2 • Pediatric vs. Adult Ear Differences

Compares Eustachian tube angle, canal size, and TM position across age groups. Explains why children have higher otitis media incidence.

Lesson 3 • External Ear Structure and Function

Covers auricle, external auditory canal, and cerumen glands. Establishes baseline anatomy for interpreting external otitis presentations.

Lesson 4 • Inner Ear and Auditory Pathway

Introduces cochlear and vestibular anatomy relevant to otitis complications. Links inner ear function to symptoms such as vertigo and hearing loss.

Lesson 1 • Chronic Suppurative Otitis Media

Examines persistent TM perforation, biofilm formation, and mucosal disease. Establishes the pathological basis for CSOM management decisions.

Lesson 2 • Otitis Media with Effusion

Covers persistent non-infected effusion, mucosal metaplasia, and hearing impact. Distinguishes OME from AOM for treatment decision-making.

Lesson 3 • Malignant Otitis Externa Pathophysiology

Describes osteomyelitis of the skull base driven by Pseudomonas in immunocompromised hosts. Highlights life-threatening progression requiring urgent recognition.

Lesson 4 • Otitis Externa Pathophysiology

Explains disruption of canal skin barrier, pH changes, and microbial invasion. Grounds clinical recognition of acute and chronic external otitis.

Lesson 1 • Chief Complaint Characterization

Teaches systematic elicitation of ear pain, discharge, hearing loss, and tinnitus. Precise symptom characterization guides the diagnostic pathway.

Lesson 2 • Medication and Allergy History

Reviews prior antibiotic courses, ototoxic drug exposure, and known allergies. Prevents treatment errors and identifies treatment-resistant cases.

Lesson 3 • Risk Factor and Exposure History

Identifies water exposure, hearing aid use, prior ear surgery, and immunosuppression. Risk factors stratify probability of specific otitis types.

Lesson 4 • Systemic and ENT Review of Systems

Screens for upper respiratory infection, allergic rhinitis, and systemic disease. Connects systemic conditions to otitis predisposition and severity.

Lesson 1 • Otoscopic Examination Technique

Teaches canal straightening, systematic TM inspection, and landmark identification. Systematic technique ensures no pathology is missed during examination.

Lesson 2 • Periauricular and Neck Examination

Assesses tragal tenderness, mastoid tenderness, and cervical lymphadenopathy. Periauricular findings indicate severity and potential complications.

Lesson 3 • Otoscope Selection and Setup

Covers speculum sizing, light source optimization, and instrument handling. Proper setup prevents patient discomfort and ensures clear visualization.

Lesson 4 • Pneumatic Otoscopy Skills

Demonstrates TM mobility assessment using controlled air pressure. Mobility findings differentiate AOM from OME and normal ears.

Lesson 1 • Differential Diagnosis of Ear Pain

Distinguishes referred otalgia from dental, temporomandibular, and pharyngeal sources. Prevents misdiagnosis when the ear examination is normal.

Lesson 2 • Diagnosing Otitis Externa

Identifies rapid-onset canal pain, tenderness, edema, and discharge as diagnostic hallmarks. Differentiates acute from chronic and fungal forms.

Lesson 3 • Identifying Otitis Media with Effusion

Uses TM color change, opacity, and reduced mobility without acute signs to diagnose OME. Guides watchful waiting vs. intervention decisions.

Lesson 4 • Red Flags and Serious Diagnoses

Screens for mastoiditis, malignant otitis externa, and cholesteatoma using specific clinical signs. Early recognition prevents life-threatening complications.

Lesson 1 • Point-of-Care Testing Applications

Reviews rapid antigen tests and acoustic reflectometry in primary care settings. Point-of-care tools improve diagnostic confidence without specialist equipment.

Lesson 2 • Microbiological Sampling Techniques

Covers swab collection from the canal and middle ear for culture and sensitivity. Proper sampling technique maximizes pathogen identification accuracy.

Lesson 3 • Imaging Indications for Otitis

Defines when CT and MRI are indicated for suspected mastoiditis or skull base disease. Imaging selection prevents radiation exposure while ensuring diagnostic accuracy.

Lesson 4 • Tympanometry Principles and Technique

Explains acoustic admittance measurement and probe placement technique. Tympanograms objectively confirm middle ear status beyond clinical inspection.

Lesson 1 • Watchful Waiting in Otitis Media

Defines patient selection criteria, safety-net prescribing, and follow-up intervals for observation. Reduces unnecessary antibiotic exposure in low-risk AOM cases.

Lesson 2 • Antibiotic Selection for Otitis Media

Applies first-line and alternative antibiotic regimens based on age, severity, and allergy status. Covers dosing principles and treatment duration for AOM.

Lesson 3 • Adjunct and Supportive Therapies

Reviews analgesics, nasal decongestants, and canal cleaning as adjuncts to primary treatment. Supportive measures improve patient comfort and treatment effectiveness.

Lesson 4 • Systemic Therapy for Severe Otitis

Addresses oral and intravenous antibiotic use for malignant otitis externa and complicated AOM. Systemic therapy is reserved for cases exceeding topical or oral treatment scope.

Lesson 1 • Intratemporal Complications of Otitis

Covers mastoiditis, labyrinthitis, facial nerve palsy, and TM perforation as local complications. Early recognition and escalation prevent permanent structural damage.

Lesson 2 • Intracranial Complications

Identifies meningitis, brain abscess, and sigmoid sinus thrombosis as life-threatening sequelae. Prompt imaging and specialist referral are mandatory for suspected intracranial spread.

Lesson 3 • Prevention Strategies and Patient Education

Covers vaccination, breastfeeding promotion, smoke avoidance, and ear hygiene counseling. Prevention reduces incidence and recurrence across all otitis types.

Lesson 4 • Treatment Failure and Recurrence

Defines treatment failure criteria, resistant pathogen workup, and recurrent AOM thresholds. Systematic reassessment prevents prolonged ineffective therapy.
