Study Notes
- Paranasal sinuses develop as an invagination from nasal fossa into their respective bones.
- Maxillary sinus is the first to develop and is most commonly developed in the second month of intrauterine life.
- Intrinsic diseases associated with maxillary sinus include mucositis, sinusitis, retention pseudocyst, polyps, and antral lith.
- Extrinsic diseases associated with maxillary sinus include various inflammatory diseases, tumors, dental structures, and bone dysplasias.
- Mucositis is characterized by localized thickening of the mucosa and is often asymptomatic.
- Sinusitis is characterized by generalized inflammatory condition of the sinus and can be acute or chronic.
- Retention pseudocyst occurs due to blockage of secretory duct of zero mucous gland in the sinus mucosa.
- Polyps are taken mucous membrane of sinus which forms irregular folds.
- Antral lith occurs due to deposition of mineral salts around an Ibis or stagnant or in feces sated mucous or cellular debris.
- Mucosal is an expanding destructive region due to blocked sinus ostium and leads to thinning displacement and destruction of sinus.
- The maxillary sinus can be affected by intrinsic and extrinsic diseases.
- Benign neoplasms of the maxillary sinus are rare, with papilloma and osteoma being the most common.
- Squamous cell carcinoma is the most common type of malignant neoplasm affecting the maxillary sinus.
- Symptoms of maxillary sinus neoplasms depend on which wall of the sinus is involved.
- Inflammatory lesions of the maxillary sinus can be caused by dental infections or periosteal newborn formation.
- Or antigen exists and benign neoplasms are the most common extrinsic lesions affecting the maxillary sinus.
- Differential diagnoses for or antigen exists include retention pseudocyst, sinusitis, and double cortex.
- Born a dysplasia, such as peripheral and florid osseous dysplasia, can also affect the maxillary sinus.
- Imaging features, such as CT scans and radiographs, can help diagnose maxillary sinus disorders.
- Treatment options for maxillary sinus disorders include surgery and radiotherapy.
- Fractured tooth roots may displace into the sinus.
- Clinical features are similar to sinusitis.
- Imaging features show radio-opaque mass.
- Molar teeth or wood fragments are commonly displaced.
- Localization is done through later maxillary or crucial view.
- Management involves removal by Caravelle loose operation.
- Anthro let's shape of radio opacity is a differential diagnosis.
- Pulp canal presence helps in comparison.
- Hyperallergic region from the floor of the maxillary sinus mimics root tip shape.
- Both intrinsic and extrinsic pathologies are associated with maxillary sinuses.
