Do maxillary sinus retention cysts reflect obstructive sinus phenomena?
OBJECTIVE To determine the relation of maxillary sinus retention cysts (RCs) to ostiomeatal complex (OMC) obstruction and anatomic variation of the paranasal sinuses. METHODS The results of 410 computed tomographic scans of the sinuses ordered by otolaryngologists in an academic center during a 1-year period were reviewed. Computed tomographic scans with maxillary sinus RCs were studied to de...
متن کاملThe incidence of maxillary sinus retention cysts in orthodontic patients.
Maxillary sinus retention cysts are occasionally found on dental radiographs. The objective of this study was to verify the frequency of maxillary sinus retention cysts in consecutive panoramic radiographs from 173 patients (77 males, 96 females) in an orthodontic office. The chi-square test was used for statistical analysis. Ten patients (5.8%) of the total sample presented a maxillary sinus r...
متن کاملMaxillary Sinus Retention Cysts Protruding Into the Inferior Meatus
Although most of the maxillary sinus retention cysts are asymptomatic, a few of them increase in size and cause symptoms. However, they rarely erode bony walls nor protrude into the inferior meatus. I present 2 cases with maxillary sinus retention cysts protruding into the inferior meatus by making a large defect on the medial wall of the maxillary sinus.
متن کاملPseudocysts and retention cysts of the maxillary sinus.
The dome-shaped radiopaque shadows frequently seen on the floor of the maxillary sinus, and sometimes inaccurately referred to as antral mucoceles, appear to represent focal accumulation of inflammatory exudate that lifts the epithelial lining of the sinus and the periosteum away from the underlying bone to form the characteristically shaped structures. Their histologic appearance is therefore ...
متن کاملCorrelations between anatomic variations of maxillary sinus ostium and postoperative complication after sinus lifting
OBJECTIVES The maxillary sinus mucosa is reported to recover to preoperative sterility after sinus floor elevation. However, when drainage of maxillary sinus is impaired, recovery can be delayed and maxillary sinusitis can occur. Therefore, in this study, we investigated the correlations between anatomic variants that can interrupt the ostium of the maxillary sinus and incidence of complication...
