In cases where the curvature unusually occurs toward the opposite side, they are called paradoxical turbinates 14, Otolaryngol Clin North Am. However, in these studies there was not a control group for statistical correlation.

Acta Otolaryngol Suppl ; CT examination for endoscopic sinus surgery Auris Nasus Larynx, 26, pp. The Anatomic Terminology Group. The anatomic relevance of the Haller cell in sinusitis. The wrong words are highlighted.

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 Local anatomic variations including concha bullosa, deviated nasal septum DNSHaller cells, paradoxical middle turbinates, agger nasi cells and many others may be the source of middle meatal obstruction and subsequent rhino sinusitis.

Researches on this theme consider that, if anatomical variants ostoemeatal predispose to sinusitis, one should expect that these variants were more frequently found at CT in patients with sinus disease symptomatic ostemeatal in the general population asymptomatic. Computed tomography offers detailed study of anatomical variations and is an invaluable tool for managing clinical decisions and planning surgical strategies.

To achieve this goal, there should be some diagnostic modalities which guide us towards exact diagnosis and safe intervention.

One or more anatomical variants Graphic 1 were identified in of the cases evaluated Head and neck surgery. Most frequent English dictionary requests: Anatomical variants of the ostiomeatal complex: Only occasionally this posterior group of sinuses is affected by inflammatory processes 3,4,6,9. The drainage to this fissure is made by the frontal sinus, through the frontal recessus, and the maxillary sinus, through the infundibula medially limited by the unciform process and laterally limited by the ethmoidal bullamiddle and anterior ethmoidal cells.


Functional endoscopic sinus surgery: J Comput Assist Tomogr ; The middle turbinate may be paradoxically curved i. Nasal septum is fundamental in the development of the nose and paranasal sinuses. Pneumatized uncinate process or uncinate bulla also has been associated with poor sinus ventilation 11,14specifically of the anterior ethmoid, frontal recess and of the infundibulum region.

The ostiomeatal unit and endoscopic surgery: Casiano 10 has defined the ostiomeatal complex as the ethmoid bulla, uncinate process and adjacent spaces and ostia draining the anterior sinuses anterior ethmoid sinus, frontal and maxillary sinuses.

It was found in Endoscopic surgery has been increasingly utilized, requiring a meticulous assessment and a detailed description of both nasal and paranasal cavities structures 2. Preoperative imaging anatomy of nasal-ethmoid complex for functional endoscopic sinus surgery. The investigation of the structures in the ethmoidal air cells on CT. Descriptive cross-sectional study design in which 54 consecutive cases of chronic rhino sinusitis patients attending the ENT outpatient department, who had chronic sinusitis for more than three months duration not responding to the medical line of treatment and who were willing to undergo Functional Endoscopic Sinus Surgery satisfying the inclusion criteria were studied.

This last observation might indicate an acquired nature of this condition External facial incisions, extensive nasal packing and prolonged hospital stays have been replaced by minimally invasive surgery. Radiol Bras ;34 Supl 1: Anatomic variations of the bone in sinonasal CT. Imaging of inflammatory sinus disease.

Functional endoscopic sinus surgery: Hypoplastic maxillary sinus appears in about 6. Deviated nasal septum was the most common anatomical variation encountered in our study followed by concha bullosa. Few studies of Indian origin have examined the putative role of anatomical variations of osteomeatal complex such osteoematal concha bullosa, septal deviation, uncinate process variations, agger nasi cells, haller cells and paradoxically curved middle turbinate in the development of traditional CRS [ 6 ].

Computed tomography studies of patients evaluated for clinical suspicion of sinusopathy were reviewed.

The radiographic incidence of chronic sinus disease in the pediatric population. Functional endoscopic sinus surgery: It is due to its negative influence on paranasal sinus ventilation and mucociliary clearance in the middle meatus region as quoted by Tonai [ 22 ]. The frontal sinus drainage pathway and related structures.

It is important to note that the degree of pneumatization found in the population studied by Tonai and Baba 1 was low, which they attribute possibly to a racial factor the study has been developed in Japan. The deviated uncinate was found in 9. The revolutionary changes in the surgical treatment of rhino sinusitis in recent years, particularly in endoscopic surgery, require 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, many of which are detectable only by the use of CT [ 7 ].

Therefore, higher frequencies are described in CT studies in which agger nasi cell can be easily identified 1,4. Int J Pediatr Otorhinolaryngol ; The frequency of anatomical variants of the ostiomeatal complex is shown on Graphic 2.

The role of osteomeatal complex anatomical variations in chronic rhinosinusitis

The drainage of the sphenoidal sinus and posterior ethmoidal complejl is performed through the sphenoethmoidal recess and through the superior meatus. It has also been suggested as a predisposing factor for impaired ventilation of the anterior group of sinuses and frontal sinus.

The differences reported in the prevalence of middle turbinate pneumatization may have been influenced by the ostsomeatal degree, and lower rates suggest that only large turbinates may have been taken into consideration.
