These cells were the least observed in our study i.

The role of osteomeatal complex anatomical variations in chronic rhinosinusitis

Look up in Linguee Suggest as a translation of “ostiomeatal” Copy. Thank you very much for your vote! Received July 13, Uncinate process insertion into other structures may result in a blind-end obstruction. The complejk were expressed in percentage and proportions. Anatomic variations of the osteomdatal sinuses: Computer tomography of nasal cavity and paranasal sinuses: Hypertrophied uncinate process causes narrowing of the hiatus semilunaris and the ethmoid infundibulum.

Dutra LD, Marchiori E. One has observed that the maxillary sinus opacification was significantly more frequent in cases where the concha bullosa determined osteomeatal complex obliteration Table 6when compared with cases of concha bullosa without osteomeatal complex obliteration. Haller cells are anterior ethmoidal cells that project beyond the limits of the bulla ethmoidal under the orbital oateomeatal, forming the infundibulum lateral wall between the papyracea lamina and the unciform process 1,13,18 Figure 4.

Hypertrophy of the uncinate process was observed in 5.

According to Lusk et al. The lateral nasal wall consists of inferior and middle turbinates and, occasionally, a superior or supreme turbinate bone with their respective meatus. Imaging of inflammatory sinus disease.

Paraseptal structural changes and chronic sinus disease in relation to the deviated septum. In measurements at CT in adults, the average area of each ethmoidal cell is 0. Earwaker 16in a study of cases, have described variants of the uncinate process in detail, classifying them in association with other variants of the ostiomeatal complex and subdividing them differently from the present study.

The concha pneumatization may occur at several degrees, from that affecting only the bulbous portion distal Figure 2 or lamellar portion compllejoor the called true variant where there is pneumatization of both portions 4 Figure 4. It is postulated that infraorbital ethmoid cells might constitute an etiological factor in the recurrent maxillary sinusitis 8but, according to Bolger et al.

The first most anterior portion of the complex includes structures surrounding the frontal recess; the second one corresponds to the structures including the maxillary sinus and middle meatus; and the third and most posterior osteomeatl includes the structures surrounding the sphenoethmoidal recess.


Headaches and sinus disease: Earwaker 16in a study of cases, have described vomplejo of the uncinate process in detail, classifying them in association with other variants of t h e ostiomeatal c o mp lex and subdividing them differently from the present study.

Headaches and sinus disease: Anatomic variation in pediatric chronic sinusitis: This last observation might indicate an acquired nature of this condition Sinusopathy is a common clinical problem that, sometimes, does not present an adequate response to medicamentous therapy. Different and frequent anatomical variants may be found in the anterior ostiomeatal complex, and a single individual may present with different variants.

In our study it was observed that Among three subtypes of concha bullosa, only the bulbous type seems to be strongly associated with symptoms. A computed tomographic guide to endoscopic sinus surgery: The deviated uncinate was found in 9.

Functional endoscopic sinus surgery: CT imaging requirements for endoscopic surgery Radiology,pp. Am J Rhinol ;3: Chronic rhino sinusitis CRS is the most common disease for which consultation of otorhinolaryngologist is sought [ 1 ]. It may determine compression of the middle concha osheomeatal consequential infundibulum obstruction 9.

The present study was aimed at evaluating the frequency and osteomeatxl of anatomical variants of the ostiomeatal complex. Lesser prevalence of paradoxically middle turbinate was observed by Wani et al. Preoperative imaging anatomy of nasal-ethmoid complex for functional endoscopic sinus surgery.
