Paranasal Sinus Diseases
Frontal Sinus
One of the paired, but seldom symmetrical, air spaces located between the inner and outer compact layers of the FRONTAL BONE in the forehead.
Ethmoid Sinus
Lip Diseases
Cystadenoma, Mucinous
A multilocular tumor with mucin secreting epithelium. They are most often found in the ovary, but are also found in the pancreas, appendix, and rarely, retroperitoneal and in the urinary bladder. They are considered to have low-grade malignant potential.
Appendiceal Neoplasms
Tumors or cancer of the APPENDIX.
Frontal Sinusitis
Inflammation of the NASAL MUCOSA in the FRONTAL SINUS. In many cases, it is caused by an infection of the bacteria STREPTOCOCCUS PNEUMONIAE or HAEMOPHILUS INFLUENZAE.
Salivary Gland Diseases
Osteoma
Pseudomyxoma Peritonei
A condition characterized by poorly-circumscribed gelatinous masses filled with malignant mucin-secreting cells. Forty-five percent of pseudomyxomas arise from the ovary, usually in a mucinous cystadenocarcinoma (CYSTADENOCARCINOMA, MUCINOUS), which has prognostic significance. Pseudomyxoma peritonei must be differentiated from mucinous spillage into the peritoneum by a benign mucocele of the appendix. (Segen, Dictionary of Modern Medicine, 1992)
Cranial Fossa, Anterior
The compartment containing the inferior part and anterior extremities of the frontal lobes (FRONTAL LOBE) of the cerebral hemispheres. It is formed mainly by orbital parts of the FRONTAL BONE and the lesser wings of the SPHENOID BONE.
Otorhinolaryngologic Surgical Procedures
Appendectomy
Surgical removal of the vermiform appendix. (Dorland, 28th ed)
Sphenoid Bone
An irregular unpaired bone situated at the SKULL BASE and wedged between the frontal, temporal, and occipital bones (FRONTAL BONE; TEMPORAL BONE; OCCIPITAL BONE). Sphenoid bone consists of a median body and three pairs of processes resembling a bat with spread wings. The body is hollowed out in its inferior to form two large cavities (SPHENOID SINUS).
Cystic Duct
Orbital Diseases
Diseases of the bony orbit and contents except the eyeball.
Exophthalmos
Appendicitis
Acute inflammation of the APPENDIX. Acute appendicitis is classified as simple, gangrenous, or perforated.
Cystadenoma
Mucocele
A retention cyst of the salivary gland, lacrimal sac, paranasal sinuses, appendix, or gallbladder. (Stedman, 26th ed)
Enophthalmos
Recession of the eyeball into the orbit.
Tomography, X-Ray Computed
Incidental Findings
Unanticipated information discovered in the course of testing or medical care. Used in discussions of information that may have social or psychological consequences, such as when it is learned that a child's biological father is someone other than the putative father, or that a person tested for one disease or disorder has, or is at risk for, something else.
Mouth Diseases
'Mouth diseases' is a broad term referring to various conditions that cause inflammation, infection, or structural changes in any part of the mouth, including the lips, gums, tongue, palate, cheeks, and teeth, which can lead to symptoms such as pain, discomfort, difficulty in chewing or speaking, and altered aesthetics.
Endoscopy
Procedures of applying ENDOSCOPES for disease diagnosis and treatment. Endoscopy involves passing an optical instrument through a small incision in the skin i.e., percutaneous; or through a natural orifice and along natural body pathways such as the digestive tract; and/or through an incision in the wall of a tubular structure or organ, i.e. transluminal, to examine or perform surgery on the interior parts of the body.
