  • the incidence of Concha bullosa and its relationship to nasal septal deviation and paranasal sinus disease
    American Journal of Neuroradiology, 2004
    Co-Authors: Jamie S Stallman, Joao N Lobo
    Abstract:

    BACKGROUND AND PURPOSE: The incidence of middle turbinate pneumatization, or Concha bullosa, has been well described in the literature. However, to our knowledge, no study has evaluated Concha bullosa in relation to nasal septal deviation. We sought to analyze the incidence of Concha bullosa and any correlation with nasal septal deviation and paranasal sinus disease. METHODS: Three neuroradiologists retrospectively reviewed findings of 1095 consecutive paranasal sinus CT studies conducted between 2001 and 2002. All examinations were performed for evaluation of a symptom referable to the sinonasal region. Paranasal sinus inflammatory disease was identified and graded as mild, moderate, or severe. Sphenoid, ethmoid, maxillary, and frontal sinuses were each graded separately on both sides. If a Concha bullosa was present, it was graded in size as small, moderate, or large. If bilateral Concha were present, sizes were compared and when one was larger, it was identified as dominant. When nasal septal deviation was present, it was graded as mild, moderate, or severe. The direction of nasal septal deviation was identified as the face of the convex surface. RESULTS: There was a clear association between the presence of a unilateral Concha, or a dominant Concha (in the case of bilateral Concha), and the presence of nasal septal deviation (P < .0001). Moreover, there was a significant relationship between the presence of Concha bullosa and deviation of the nasal septal to the contralateral side (P < .0001). This inverse association was present regardless of the size of the Concha bullosa or degree of septal deviation. In every case, there was some preservation of air channels between the dominant Concha and the nasal septum. Seventy-three percent of patients with Concha bullosa had paranasal sinus inflammatory disease; 78% of patients without Concha bullosa also had some form of inflammatory disease. CONCLUSION: Concha bullosa is a common anatomic variant. There is a strong association between the presence of a Concha bullosa and contralateral deviation of the nasal septum. Nasal septal deviation away from the dominant Concha, with preserved adjacent air channels, suggests that the deviation is not a direct result of mass effect from the Concha. No increased incidence of paranasal sinus disease exists in patients with Concha bullosa.

  • Case Report Bilateral Triple Concha bullosa: A Very Rare Anatomical Variation of Intranasal Turbinates
    2016
    Co-Authors: Turhan San, Selma San, Emre Gürkan, Barjg Erdolan
    Abstract:

    Copyright © 2014 Turhan San et al. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Pneumatization of the intranasal turbinates or Concha bullosa is an anatomic variation of the lateral nasal wall. Concha bullosa is defined as the presence of air cells in turbinates. It can be best diagnosed with paranasal sinus computed tomography. Concha bullosa is a possible etiologic factor for recurrent sinusitis due to its negative effect on paranasal sinus ventilation and mucociliary clearance. Concha bullosa is most commonly seen in the middle turbinate and less frequently in the inferior or superior turbinate. Pneumatization of all turbinates is very rare. To our knowledge, there are only two publications about a case with Concha bullosa in all turbinates in the current literature. Here, we present a woman with bilateral pneumatization in all three intranasal turbinates. 1

  • The role of septated Concha bullosa on sinonasal pathologies
    European Archives of Oto-Rhino-Laryngology, 2015
    Co-Authors: Turhan San, Selma San, Emre Gürkan, Baris Erdogan
    Abstract:

    The purpose of this study was to retrospectively determine the possible role of septated Concha bullosa on sinonasal pathologies. Paranasal sinus computerized tomography scans of patients with symptoms of headache, postnasal drip, nasal obstruction and smell disorders were retrospectively evaluated. Twenty-eight subjects with unilateral septated Concha bullosa and 13 subjects with unilateral Concha bullosa without septation were selected as the study and control groups, respectively. Both groups were compared according to the presence of septal deviation and sinus pathology. There were no statistically significant differences in baseline characteristics (age and gender) between the groups. Sinus involvement was found in 20 patients (71.4 %) in the study group and in 10 patients (76.9 %) in the control group. The most common pathology accompanying septated Concha bullosa was maxillary sinusitis (65 %), and ethmoid sinus was the second most involved sinus (25 %). Similar results in terms of sinus involvement were also seen in the control group. Septal deviation was seen in 18 patients in the study group (64.2 %) and in 12 patients in the control group (92.3 %). Eventually, there was no statistically significant difference between septated and non-septated Concha bullosa groups according to the accompanying sinonasal pathologies.

  • bilateral superior Concha bullosa a rare case overlooked
    KBB Journal of ear nose and throat, 2014
    Co-Authors: Turhan San, Baris Erdogan, Bulent Tasel
    Abstract:

    Concha bullosa is generally defined as the pneumatization of the middle turbinate and, rarely, of the superior or the inferior turbinates. A symptomatic pneumatization of the superior turbinate is extremely rare. When symptomatic, Concha bullosa may cause various problems. Concha bullosa can be easily recognized in paranasal sinus computed tomography. In this article we present a very rare case with bilateral pneumatization of the superior turbinates in a patient with relevant symptomatology.

  • triple divided Concha bullosa a new anatomic variation
    Case reports in otolaryngology, 2013
    Co-Authors: Turhan San, Baris Erdogan, Bulent Tasel
    Abstract:

    In recent years, with the widespread use of imaging techniques such as paranasal sinus computed tomography (CT), many variations of nasal turbinates have been described. One of these variations known as Concha bullosa (CB) is pneumatization of nasal turbinates. CB is the most frequently encountered anatomical variations of the middle turbinate. The term of septated Concha bullosa has been described recently and it is an uncommon pneumatization anomaly of the middle turbinate. There has not been any study that correlates the number of septations and the presence of sinonasal pathologies. We hereby present a case of triple septated Concha bullosa that has not been reported so far.
