Maxillary sinus mucosal cysts (MSMC) are benign entities that result either from the obstruction of the duct of a seromucinous gland at sinus mucosa, which in turn causes accumulation of mucus and cystic dilatation of the gland, i.e. secretory mucosal cysts or retention cysts, or from the accumulation of fluid between the epithelial layer and underlying mucosal lining of the maxillary sinus, i.e. non-secretory mucosal cysts. In most cases, these cysts are asymptomatic, self-limiting and discovered incidentally on Cone Beam Computed Tomography . application of CBCT

Sharing a Case of Styloid Process Elongation, (Eagle's Syndrome) with recurrent pain in oropharynx region.

Eagle’s syndrome (ES) is characterized by recurrent painin the oropharynx and face secondary to calcificationof the stylohyoid ligament (SHL) or elongated styloidprocesses (ESP) greater than 30 mm .

ES can occurunilaterally or bilaterally and frequently results in symptoms of dysphagia, recurrent throat pain and foreign object sensation, referred otalgia, headache, pain on rotation of the neck, dizziness, pain on extension of the tongue,pain on opening mouth, discomfort during chewing,change in voice, and a sensation of hypersalivation.
Diagnosis is guided both by clinical and radiologic examination. Palpation of the styloid process (SP) in the tonsillar fossa is indicative of elongation .
The general structural appearances of SP and calcifications and ossifications of SHL were also evaluatedaccording to the system of Langlais et al.

The morphology of the stylohyoid complex was classified into threetypes:

Type 1 represents an uninterrupted, elongated SP.

Type 2 is characterized by the SP apparently being joinedto the SHL by a single pseudoarticulation.

Type 3 consists of interrupted segments of the mineralized ligament,creating the appearence of multiple pseudoarticulationswithin the ligament.

Calcification patterns of SP wereclassified into four types:

Pattern A (calcified outline) de-
scribes a thin radiopaque border with a central radiolucency that constitutes the majority of the process.

Pattern B (partially calcified) describes a process that hasa thicker radiopaque outline and complete opacificationbut small, sometimes discontinuous, radiolucent cores.

Pattern C (nodular) has a knobby or scalloped outline. Itmay be partially or completely calcified with varyingdegrees of central radiolucency.

Pattern D (completelycalcified) is totally radiopaque with no evidence of a radiolucent interior.

In the recent past, three-dimensional (3-D)
cone-beam computerized tomography (CBCT) whichcan definitively measure the length of the anatomicalstructures of craniofacial region is introduced as a newand alternative modality. CBCT allows images to beacquired with a low dose of radiation, shorter patientexamination time and lower costs than conventionalCT, which make its routine use practicable for oral and maxillofacial imaging and surgical procedures. Thisrecently-designed technology has become a relevanttool for diagnostic imaging of oral and maxillofacial osseous structures, providing to professionals access to excellent image quality and greater diagnostic accuracy andsensitivity.

Sharing case of Bony EXOSTOSIS in middle ear.

Surfer's ear is the common name for an EXOSTOSIS or abnormal bone growth within the ear canal. ... Irritation from cold wind and water exposure causes the bone surrounding the ear canal to develop lumps of new bony growth which constrict the ear canal.

Cone-beam imaging now rivals or improves on CT data. Full topographic and etiological sinus assessment can be performed using relatively simple and low-cost technology entailing little radiation. Incomparable dental exploration immediately settles the etiological issue in certain types of sinusitis. CBCT will eventually become the gold standard in routine sinus exploration, with techniques involving higher radiation levels and/or costs being reserved for certain pathologies, notably tumor . For the ear, it is an excellent alternative, with a lower radiation level, and more effective if the indication is precise. However, only equipment allowing high resolution with a good signal-to-noise ratio can be used for pars petrosa exploration. As the radiation level is lower than in CT, CBCT is ideal for iterative examination, postoperative follow-up and pediatric exploration. Study of conductive hearing loss with normal tympanum, exploration for malformation or for cholesteatoma or cholesteatoma surveillance in children old enough to keep still, requires results identical to those of CT, and could greatly benefit from CBCT. In pathologies needing iterative examination, CBCT is to be preferred due to the lower radiation level. Assessment of traumatic bone lesions of the pars petrosa or maxillofacial bones without associated neurologic or cranial lesions can be performed rapidly and easily on CBCT. The technique’s limitations, however, need to be borne in mind. It is remarkably good in bone study, with excellent bone/mucosa/air contrast, but its poor density resolution is a drawback for soft-tissue contrast studies. In case of tumoral, septic or hematic soft-tissue infiltration, CT or MRI is mandatory. Likewise, no intravascular contrast medium injection is possible on CBCT.
