National Center for Biotechnology InformationU. Considering that the main objective of this type of surgery is to reopen the natural ways of drainage of paranasal cavities, it is very important that the complejk is aware of the ostiomeatal complex variants, describing them in a comprehensible way for the otorhinolaryngologist The radiographic incidence of chronic sinus disease in the pediatric population. The approach to patients with chronic rhino sinusitis is endoscopic surgery which aims at removing the obstruction of the main drainage pathway.

The association of anterior ethmoidal cells and maxillary sinuses with tomographic alterations may depend not only on the subtype, but also on dimensions of the concha bullosa This article provides an updated review, showing points that seem to be of agreement about what remains undefined on this theme.

Desenvolvimento dos seios paranasais: Variations and tomographic signs of sinusal disease occurring on the same side reinforce oxteomeatal likelihood of interference with the mucus drainage process.

Anatomic variations of the paranasal sinuses: An assessment of sinonasal anatomic variants potentially associated with recurrent acute rhinosinusitis. Anatomic variations in pediatric chronic sinuisits.


Over the past few decades, both CT and nasal endoscopy have been used successfully as diagnostic modalities in sinus disease. We sought herein to examine the prevalence of these osteomeatal complex variations in the CRS cases through the use of computed tomography.

A computed tomographic guide to endoscopic sinus surgery: Surgical anatomy and variations of the onodi cell. Accepted after revision September 14, Its size is an important factor when associated with opacification of anterior ethmoidal cells at CT in patients diagnosed with sinusopathy In one of these studies 4the bulbous-type middle concha bullosa was the only anatomical variant presenting a relation with sinusopathy Table 3.

Thus male to female ratio was 1: Our study included 32 females and 22 males. The most common anatomical variants of the uncinate process are represented by insertion into an unusual topography and pneumatization. Middle turbinate or middle concha Concha bullosa is one of the most frequently found anatomical variants 22, Findings of several studies on the theme are summarized in Tables 1 to 6. Similar finding were observed by Perez et al. Ann Osteomatal Rhinol Laryngol Suppl ; These measures were similar in cadaver skulls CT scan evaluation of the osteomeatal complex.

Awareness of the possibility of such variations helps in making surgical decisions. This in turn requires the surgeons to have detailed knowledge of the anatomy of the lateral nasal wall, paranasal sinuses and surrounding vital structures and of the large number of anatomical variants in the region.

The middle concha bullosa is a result of pneumatization of the osseous plate due to ethmoidal osteomeatzl Figures 2 and 3. J Comput Assist Tomogr. Development of the paranasal sinuses in children: Hypertrophied uncinate process causes narrowing of the hiatus semilunaris and the ethmoid infundibulum.

Conclusion In light of the results obtained complejjo our study, it can be concluded that: Auris Nasus Larynx ; In our study it was observed that 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.

Sinusopathy is a common clinical problem that, sometimes, does not present an adequate response to medicamentous therapy.
