目的探讨鼻中隔偏曲并下鼻甲肥大的手术方式及效果。方法 55例以鼻塞为主诉的鼻中隔偏曲合并下鼻甲肥大患者,随机分为联合治疗组33例,行鼻中隔偏曲矫正+下鼻甲外移术;鼻中隔矫正组22例,单纯行鼻中隔偏曲矫正术。结果所有患者术后随访1年以上,联合手术组中25例痊愈,8例有效,治愈率75.8%,好转率100.0%;鼻中隔矫正组中7例痊愈,11例有效,4例无效,治愈率31.8%,好转率81.8%。两组差异具有统计学意义(P<0.01)。结论通过鼻窦CT结合鼻内镜技术实施针对性的鼻中隔偏曲矫正+下鼻甲外移术治疗,组织损伤小,安全可靠,效果肯定,符合功能性治疗的原则,可使鼻塞患者获得良好的治疗效果。     

鼻中隔偏曲伴下鼻甲肥大患者的鼻窦CT分析

目的　通过对鼻中隔偏曲患者鼻窦CT的测量分析,初步评价鼻中隔偏曲程度与下鼻甲肥大的相关性。方法　分析98例鼻中隔偏曲患者鼻窦冠状位CT,将与鼻中隔偏曲方向一致的鼻腔设为对照组,与鼻中隔偏曲方向相反的鼻腔设为实验组。测量并记录鼻中隔偏曲角度,双侧下鼻甲骨、内侧黏膜、外侧黏膜厚度。结果　实验组和对照组下鼻甲内侧黏膜、骨、外侧黏膜厚度差异有统计学意义（P <0.05）。实验组下鼻甲内侧黏膜、骨、外侧黏膜厚度差异有统计学意义（P <0.05）。实验组下鼻甲内侧黏膜、骨、外侧黏膜厚度与鼻中隔偏曲角度的相关性无统计学意义,但相关系数r 提示三者与鼻中隔偏曲角度的相关性：骨＞内侧黏膜＞外侧黏膜。结论　鼻中隔偏曲伴代偿性下鼻甲肥大,不仅由下鼻甲黏膜增厚引起,也可由下鼻甲骨本身增生引起,鼻中隔矫正术术前行鼻窦CT检查,对鼻中隔偏曲伴下鼻甲肥大患者手术方式的选择有一定帮助。

目的探讨鼻内镜下微创治疗鼻中隔偏曲伴下鼻甲肥大的疗效。方法对我科199例鼻中隔偏曲伴下鼻甲肥大采用鼻内镜手术,行鼻中隔矫正术;用4mmStryher微型电动切割器作下鼻甲黏膜下部分切除术。结果随访6～30个月,该方法对199例均能彻底地矫正鼻中隔偏曲,尤其是高位、后段的鼻中隔偏曲,能安全有效地减少下鼻甲体积,满意地改善病人的鼻腔通气,防止术后鼻腔干燥结痂及并发萎缩性鼻炎。仅有1例病人术后并发鼻中隔穿孔。结论该方法与传统的鼻中隔矫正术及下鼻甲手术比较,更加安全有效,既能保持疗效持久,又能保存下鼻甲的正常功能,具有较好的临床应用价值。     

鼻中隔高位偏曲与鼻窦炎

本文应用鼻窦冠状位ＣＴ及鼻内窥镜对鼻窦炎组和非鼻窦炎组的鼻中隔偏曲进行了观察。结果显示鼻窦炎组的鼻中隔高位偏曲的发病率明显高于非鼻窦炎组（Ｐ＜０．０５），而且偏曲侧中鼻道均较狭窄。非高位偏曲的发病率二组之间无显著差异（Ｐ＞０．０５）。表明鼻中隔高位偏曲导致偏曲侧中鼻道狭窄，影响了鼻窦的引流易诱发鼻窦炎，提示鼻内窥镜下鼻窦手术中应积极矫正鼻中隔高位偏曲，这对提高术后中鼻道的宽畅及良好引流，防止中鼻道粘连起重要作用。

The relationship between the concha bullosa,nasal septal deviation and sinusitis

OBJECTIVES: To evaluate the possible relationship between concha bullosa, nasal septal deviation and sinusitis. PATIENTS AND METHODS: Paranasal sinus computed tomography scans of patients suffering from rhinosinusitis were examined. Fifty-four patients with concha bullosa were included in the study. The relationship between concha bullosa, nasal septal deviation and sinusitis was investigated. RESULTS: A statistically significant relationship between unilateral concha bullosa and nasal septal deviation was found (p < 0.01). The relationships of unilateral and bilateral concha bullosa with sinusitis, and bilateral concha bullosa with nasal septal deviation were not statistically significant (p > 0.05). CONCLUSION: In order to define the relation between the concha bullosa, nasal septal deviation and sinusitis, more detailed investigations are needed.     

Efficiency of external nasal dilators in pediatric nasal septal deviation

Inroduction

Nasal septal deviation results from irregular development of the nasomaxillary complex and trauma. Treatment of nasal septal deviation in pediatric patients is one of the biggest challenges in rhinology. Surgery may alter craniofacial growth patterns, and so it may be indicated only in the selected cases. The use of external nasal dilators is a relatively new treatment modality in nasal obstruction.

Objective

This study was performed to assess the efficacy of external nasal dilator in pediatric nasal septal deviation patients.

Methods

Seventy-six children who were diagnosed with nasal septal deviation at our outpatient clinic were included in the study. The patients were divided into 2 groups: the external nasal dilator group was composed of 48 children that had used an external nasal dilator for at least 1 month and still been using, while the control group was comprised of 28 children that had not received any treatment and had not used an external nasal dilator. The parents of the children were asked to complete the obstructive sleep apnea 18 questionnaire. In addition, the external nasal dilator group was asked to complete the questionnaire after stopping external nasal dilator use for 2 weeks and the control group also repeated the obstructive sleep apnea 18 questionnaire.

Results

The obstructive sleep apnea 18 questionnaire results were significantly different between the external nasal dilator group and the control group at the beginning of the study (i.e., when patients in the external nasal dilator group were still using their dilators, P = 0.000). On the other hand, there was no difference between the 2 groups after the patients in the external nasal dilator group had stopped using their external nasal dilator (P = 0.670).

Conclusion

External nasal dilator use relieved nasal septal deviation, which narrows the nasal valve. The results of this study suggest that external nasal dilator could be used in patients that are not candidates for septoplasty.     

Choanal polyp originated from the inferior nasal concha

Almost all choanal polyps originate from the maxillary sinus and a choanal polyp (CP) originating from the inferior nasal concha (INC) is a rare entity. It presents in a similar manner to the more common antrochoanal polyp and may be confused on anterior rhinoscopy. In this report, an unusual case of a CP taking origin from the INC that was removed by endoscopic endonasal surgery in a young man is presented. No intraoperative or postoperative complication occured, and the symptoms immediately resolved after the operation. Although very rare, CPs arising from the INC should be kept in mind in the differential diagnosis of a solitary nasal polyp.     

Numerical study of the aerodynamic effects of septoplasty and partial lateral turbinectomy

OBJECTIVES: To investigate, first, the effects of septal deviation and concha bullosa on nasal airflow, and second, the aerodynamic changes induced by septoplasty and partial lateral turbinectomy, using computational fluid dynamics (CFD). METHODS: A three-dimensional model of a nasal cavity was generated using paranasal sinus computed tomography images of a cadaver with concha bullosa and septal deviation. Virtual septoplasty and partial lateral turbinectomy were performed on this model to generate a second model representing the postoperative anatomy. Aerodynamics of the nasal cavity in the presence of concha bullosa and septal deviation as well as postoperative changes due to the virtual surgery were analyzed by performing CFD simulations on both models. Inspiratory airflow with a constant flow rate of 500 mL/second was used throughout the analyses. RESULTS: In the preoperative model, the airflow mostly pass through a narrow area close to the base of the nasal cavity. Following the virtual operation, a general drop in the maximum intranasal air speed is observed with a significant increase of the airflow through right middle meatus. While in the preoperative model the greatest reduction in pressure is found to be in the localization of anterior septal deviation on the right side and confined to a very short segment, for the postoperative model, it is observed to be in the nasal valve region in both nasal cavities. Following septoplasty and partial lateral turbinectomy, total nasal resistance is reduced significantly. CONCLUSIONS: CFD simulations promise to make great contributions to understand the airflow characteristics of healthy and pathologic noses. Before surgery, planning for any specific intervention using CFD techniques on the nasal cavity model of the patient may help foreseeing the aerodynamic effects of the operation and might increase the success rate of the surgical treatment.

Assessing the efficacy of a modified crushing technique for the management of concha bullosa: a cone beam computer tomography study

IntroductionAlthough many surgical techniques exist to manage obstructive concha bullosa, there continues to be a drive to find the least invasive technique with the fewest complications and best results.ObjectivesThe purpose of this study is to describe and assess the short- and long-term efficacy of a modified crushing technique for concha bullosa management.MethodsPatients who met inclusion criteria underwent a detailed nasal examination and cone beam computed tomography imaging prior to and after septoplasty with crushing surgery for obstructive concha bullosa. Patients were divided into short- and long-term groups based on their followup period such that the short-term group had a mean followup of 15.14 months (range 6–22 months) and the long-term group had a mean followup of 56.66 (range 29–80) months.ResultsTwenty-four cases of obstructive concha bullosa were included in this study with 13 short-term and 11 long-term follow-ups. All patients showed a significantly decreased postoperative CB size (p < 0.001). There was no correlation between age and postoperative CB change in area (p = 0.39) and no significant difference in the amount of postoperative CB area reduction between the short-term and long-term groups (p = 0.35). No patients experienced bleeding, synechia, conchal destruction, or olfactory dysfunction on followup evaluations.ConclusionsOur modified crushing technique is a simple, effective, and lasting treatment option for concha bullosa. From our experience, there have been no complications and no instances of concha bullosa reformation during the follow-up period.
