Study Notes
Overview of Maxillary Sinus Anatomy, Histology, and Common Pathologies
- The maxillary sinus is the largest of the paranasal sinuses and occupies the body of the maxilla.
- The sinus lies superior to the molar and premolar teeth, with the lowest part opposite the second premolar and first molar about 1cm below the level of the floor of the nose.
- The opening of the sinus is in the posterior part of the hiatus semilunaris, in the middle meatus of the nose, and enters the upper medial wall of the sinus.
- The shape of the sinus is an irregular three-sided pyramid, with the apex at the zygomatic process of the maxilla and the roof as the floor of the orbit.
- Inflammatory cells are present in the sinus lining as the first line of defense against airborne pathogens coming through the nose.
- Common pathologies of the maxillary sinus include inflammation, infection, allergy, cysts, and tumors.
- Acute maxillary sinusitis is usually caused by bacterial or viral infection and presents with facial or jaw pain, clear or purulent drainage, and sometimes fever or leukocytosis.
- Chronic maxillary sinusitis is often asymptomatic or presents with vague pressure, pain, or halitosis, and is difficult to treat.
- Allergic maxillary sinusitis is seasonal and presents similarly to chronic sinusitis but with significant eosinophil infiltrate in the lining.
- Deep fungal infection of the maxillary sinus is more commonly seen in immunocompromised, malnourished, or uncontrolled diabetic patients and may cause ischemic necrosis or invade blood vessels.
- Antral pseudocysts are dome-shaped radiopacities in the floor of the sinus, likely caused by odontogenic infection, and may be asymptomatic or require root canal therapy.
- Sinus mucoceles are caused by obstruction of the sinus ostium and present with pain, expansion, and destruction, and require excision or endoscopy to unblock the fibrous tissue.
- Retention cysts are caused by blockage of gland ducts or inverted respiratory epithelium and are small and asymptomatic, often found within an antral polyp, and require excision.
