Study of relationship of concha bullosa to nasal septal deviation and sinusitis

Objectives

To study the etiological role of concha bollosa in deviated nasal septum (DNS) and sinusitis.

Materials and methods

In this retrospective study 419 consecutive CT scans of paranasal sinuses done between October 2005 and September 2007 were serially evaluated for the presence of concha, DNS and sinusitis.

Results

Out of 419 CT scans evaluated, concha bullosa was present in 40.3% of patients. Among these, concha co-existent DNS was found in 87.5%, air column between DNS and concha was found in 88.5% and sinus disease was present in 69.2% of patients.

Conclusion

Presence of air column between DNS and concha excludes the etiological role of concha in DNS. Concha bullosa may predispose to sinusitis.     

Morphometric analyses of the development of nasal cavity in human fetuses: An anatomical and radiological study

Objective

It was aimed to research the morphometric development of the nasal cavity with dissection and radiological scanning methods and to detect anatomical variations.

Design

Retrospective study.

Setting

Departments of Anatomy and Radiology, Meram Medical Faculty, Selcuk University.

Patients

Dissection stage was performed on 80 spontaneously aborted fetuses (40 males and 40 females) (63 second trimesters and 17 third trimesters) between 13 and 40 weeks of gestation. Radiological scanning stage was carried out on 40 spontaneously aborted fetuses (19 males and 21 females) (12 second trimesters and 28 third trimesters) with multi-detector computed tomography.

Methodology

One hundred and sixty nasal cavities and related structures were examined by means of bilateral dissection. Reference images were obtained in the axial plane with 3-mm collimation using multi-detector computed tomography (MDCT; Sensation 64, Siemens, Erlangen, Germany). These reference images were sent to the workstation (Leonardo, Siemens, Germany) and three-dimensional (axial, sagittal, and coronal) reformatted images with 1 mm thickness were obtained via multiplanar imaging method.

Results

In the dissected fetuses 16 suprema nasal conchae were determined. Six (15%) NSDs (four towards the left and two towards the right) were detected on radiological sections. The angle between the virtual line from sphenoidal sinus ostium through limen nasi and the horizontal plane was 32.72 ± 3.3° on average.

Conclusion

It was thought that some anatomic variations (e.g. suprema nasal concha, nasal septum deviation) occur in the fetal period; however, other certain differences (e.g. Onodi, Haller, and Agger nasi cells, concha bullosa) might be with effects of environmental factors (trauma and chronic infections) in postnatal period.

药物性鼻炎治疗体会

目的：总结药物性鼻炎在临床工作中治疗体会。方法：回顾性分析药物性鼻炎30例,其中25例停止血管收缩剂滴鼻,口服仙璐贝同时辅舒良喷鼻,3例鼻内窥镜下行双侧下鼻甲等离子消融术,2例并发双侧下鼻甲骨质增生,鼻内窥镜下行双侧下鼻甲黏膜下增生骨质部分切除术。术后开始口服仙璐贝同时辅舒良喷鼻。结果：痊愈25例,有效3例,无效2例,总有效率93.3%。结论：通过口服仙璐贝和鼻腔喷雾类固醇及鼻内窥镜下下鼻甲局部处理对药物性鼻炎有良好疗效。     

利用Ⅲ度小耳畸形残耳组织行再造耳耳屏及耳甲腔成形

目的探讨采用全扩张法对残耳组织量较少的Ⅲ度小耳畸形患者行全耳再造术,合理利用残耳组织行耳屏及耳甲腔成形。方法新方法组对36例组织量较少的Ⅲ度小耳畸形患者,一期采用经残耳切口,在耳后无发区浅筋膜深面及有发区浅筋膜浅层双平面埋置大容量扩张器(150 ml);二期行自体肋软骨支架无需植皮的全扩张法全耳再造术;三期时将残耳垂皮肤进行合理设计,用于再造耳屏并覆盖部分耳甲腔创面,残耳软骨用于作为耳屏的内支撑或垫于支架深面以增加支架的高度。传统扩张组46例,三期时将残耳垂转移以再造耳垂,采用M形皮瓣法再造耳屏,耳甲腔区游离植皮。三期再造耳修整后6~12个月随访,对耳屏和耳甲腔的大小及患者的满意度进行评价。结果新方法组患者术后耳郭表面均无明显切口瘢痕,仅1例患者残耳垂皮瓣远端覆盖耳甲腔部位存在约0.6 cm×0.4 cm大小皮瓣表皮水泡,经换药10 d后愈合。传统扩张组中可见5例患者耳甲腔移植皮片表面出现水泡,经换药后愈合。与传统扩张组相比,新方法组耳屏挛缩变形轻,耳甲腔回缩率小。新方法组患者满意率明显高于传统扩张组(P<0.05)。耳垂丰满度与正常耳相比略差。结论采用全扩张法可以扩张足够的皮肤,用于完全覆盖整个软骨支架的表面,无需行耳垂转位,再造耳支架表面无手术瘢痕,且残耳组织可以得到充分利用,再造的耳屏及耳甲腔外形良好。     

Is there a relationship between middle concha bullosa and ethmoid roof asymmetry?

IntroductionThe middle turbinate and ethmoid roof are intranasal structures and may have many anatomical variations. These structures, which serve as anatomical markers during functional sinus surgery, are important for preventing complications and performing a proper surgery. Knowledge of anatomical variations will increase surgical success and reduce complications.ObjectiveWe aimed to investigate the presence of asymmetry in the ethmoidal roof and anatomical variation in patients with and without concha bullosa.MethodsIn this study, the files of patients who underwent paranasal computed tomography between 2012 and 2018 were analyzed retrospectively. The patients were divided into two groups, as patients with and without concha bullosa. Differences between the two groups in terms of age, gender, septum deviation, ethmoid artery dehiscence, ethmoid roof asymmetry were examined.ResultsThe 369 patients included in our study were divided into two groups; those with concha bullosa and those without concha bullosa. The mean age of the patients with concha bullosa was 36.1 ± 13.4 (min–max: 12–74) and the mean age of patients without concha bullosa was 37.5 ± 14.3 (min–max: 10–81). The ethmoid roof depths were compared between the two groups and a significant difference was observed (p < 0.001). The ethmoid roof depth was higher in the group with concha bullosa (p < 0.001).ConclusionThe results of our study indicate that the ethmoidal roof tends to be higher in patients with middle concha bullosa.     

Management of Prominent Ears: Personal Approach

Various methods for correcting prominent ears have been reported. Although anterior cartilage antihelix abrasion combined with posterior retention sutures is a conventional procedure, it does not include anterior conchal cartilage abrasion and thus allows easier reduction of the condromastoid angle. A simple and effective technique is described that involves using a rasp to score the whole anterior surface of the auricular cartilage, including the concha, in combination with Mustarde-type conchal-antihelical and conchal-mastoid retention sutures. This method was applied to 342 patients (675 ears) over 23 years, who were followed up for periods varying from 18 to 24 months. Good results were obtained for all patients with minimal complications.     

Fungal ball in concha bullosa as incidentaloma: A case report and the review of the literature

Concha bullosa is an anatomic variant consisting in an enlargement and pneumatization of the middle nasal turbinate. A fungal ball (FB) localized in this structure is an extremely rare disease. This article describes the unusual case of a young patient with an asymptomatic fungal mass in the concha bullosa, incidentally discovered at computed tomography (CT) scan of the head, which was performed after trauma.
