Applied Anatomy

When you enter clinical rotations you need to apply the knowledge of Anatomy to clinical practice.

• What is the function of the sinuses?
• What is the significance of the location of the drainage site of sinus?
• What is the significance of nasal turbinates hypertrophy and sinus drainage?
• Why is the maxillary sinus is the most common sinus to get infected?
• What is the anatomical basis for the type of infecting organisms in sinusitis?
• How does maxillary sinusitis spread to the orbit?
• How does infected teeth extend to the maxillary sinus?
• How does ethmoid sinusitis extend to the brain and meninges?
• How does sphenoid sinusitis extend to the brain and meninges?
