鼻中隔偏曲与上颌窦气化分型的相关性分析

目的 探讨鼻中隔偏曲与上颌窦气化分型的关系。方法 实验组纳入CT结果显示鼻中隔偏曲且无鼻窦合并症的患者100例,对照组为CT结果显示鼻中隔无偏曲患者60例。使用美国GE Light Speed 64层螺旋CT进行图像观测,观察上颌窦气化程度及鼻中隔偏曲的程度,比较鼻中隔偏曲与上颌窦气化之间的关系。采用SPSS 22.0软件对数据进行统计处理。结果 鼻中隔偏曲患者中,54.0%(n=54)鼻中隔偏向右侧,46.0%(n=46)鼻中隔偏向左侧;鼻中隔偏曲角度5.4°～31.1°,平均(12.8±4.1)°,鼻中隔偏曲患者与对照组相比,其性别分布差异具有统计学意义(χ²=12.62,P<0.05),性别分布与鼻中隔正常的上颌窦气化之间差异具有统计学意义(χ²=4.32,P<0.05)。Ⅰ型和Ⅲ型上颌窦与鼻中隔偏曲角度之间存在相关性(r=0.27,P<0.05)。鼻中隔是否偏曲与上颌窦的气化分型之间存在显著的关系(χ²=18.52,P<0.05)。结论 男性更容易出现鼻中隔偏曲及上颌窦过度气化。鼻中隔是否...     

Anterior pneumatization of the maxillary sinus — Presenting as a facial swelling

Over pneumatization of the paranasal sinuses is a fairly common finding on computerized tomography; but involvement of a small segment of the maxillary sinus especially the anteromedial aspect is very rare. We report a case of a twenty year old male who presented with a facial swelling. On CT scan, the swelling was found to be due to pneumatization of the anterior part of the maxillary sinus. Surgical treatment was carried out for cosmetic reasons.     

Schwannoma of maxillary sinus

Schwannoma, also known as neurilemmoma, is a solitary, encapsulated peripheral tumour of neuroectodermal derivation that originates from schwann cells of neural sheath of motor/ sensory peripheral nerves or sympathetic nerves. About one- third of all schwannomas occur in head and neck region but nose and paranasal sinuses, are rare sites. We report a case of schwannoma arising from the maxillary sinus and eroding the orbital floor. To the best of our knowledge, this is the sixth; case of schwannoma solely arising in the maxillary sinus, reported in the literature.

Congenital maxillary sinus cholesteatoma

Cholesteatoma of the paranasal sinuses is a rare condition. The purpose of this paper is to present a child with a congenital maxillary sinus cholesteatoma. An 18-month-old girl presented with a 4-week history of right cheek and intraoral swelling. Examination revealed a smooth swelling of the right hard palate in association with the facial swelling in the maxillary region. An inferior meatal antrostomy revealed pultaceous debris in the right maxillary antrum and biopsy confirmed a maxillary sinus cholesteatoma. The inferior meatal antrostomy was enlarged to allow exteriorisation of the disease. Recurrence of the disease has not presented on follow-up. An exteriorisation procedure as performed, in child of this age, allows normal facial growth. If recurrence develops then further treatment may be instituted in a more mature facial skeleton.     

Haemangioma of maxillary sinus

Though haemangioma of nose is a common tumor, those arising from the paranasal sinuses are not very common. Very few cases have been reported. Because of its rarity under the backdrop of existing literature we are reporting our present case.     

Compartmentalized maxillary sinus mucocele

A rare case of compartmentalized maxillary sinus mucocele 12 years after a Caldwell-Luc operation is reported. The two separate mucoceles were drained intranasally by endoscopic sinus surgery. The clinical features of this mucocele are presented and the incidence, presentation and theories on formation of post-operative mucoceles are reviewed.     

鼻内窥镜术上颌窦自然开口的处理

目的探讨内窥镜鼻窦手术治疗慢性鼻窦炎、鼻息肉的上颌窦中鼻道开口的重要性及处理方法。方法配对研究５６例双侧鼻窦炎、鼻息肉患者，比较同一患者术中扩大或不扩大上颌窦自然开口的术后情况。结果窦口的开放率在不扩大和扩大上颌窦自然开口的术侧中分别为９２．９％和８０．４％（随访６个月时）。回顾性观察５１例施ＣａｌｄｗｅｌＬｕｃ术的患者，下鼻道造口的术后开放率仅为４０．６％。分析３８张单侧鼻窦炎或鼻息肉的鼻窦ＣＴ片，测量对照侧与病变侧的上颌窦口膜样部的上下径和前后径，差异无显著性。病变侧上颌窦口周围的中鼻甲气化、增生及钩突偏曲、筛泡骨性增生等解剖结构异常的发生率明显高于对照侧（Ｐ＜０．０５）。结论鼻内窥镜下处理上颌窦自然开口的关键是窦口周围的解剖异常因素。     

Ethmomaxillary sinus and hypoplasia of maxillary sinus.

In a series of 410 coronal CT scans performed to assess paranasal sinus disease, we have identified eight cases in which an ethmomaxillary sinus was present. The ethmomaxillary sinus was unilateral in five cases and bilaterally present in three. The sex incidence was equal. Four patients had generalized mucosal disease of their paranasal sinuses which included the ethmomaxillary sinus whereas four patients had osteomeatal complex disease and sparing of their ethmomaxillary sinus. The characteristic radiological features of an ethmomaxillary sinus were drainage into an enlarged superior meatus, reduction in the size of the maxillary sinus and a normal bony orbital cavity. The differential diagnosis of an apparently hypoplastic maxillary sinus is briefly discussed.     

Comparison of maxillary sinus specimens removed during Caldwell-Luc procedures and traditional maxillary sinus antrostomies

The cases of 80 patients who underwent Caldwell-Luc surgery for the treatment of chronic rhinosinusitis between 2002 and 2007 at Vanderbilt University Medical Center's Department of Otolaryngology were reviewed. Data on demographics, comorbidities, details of surgery, surgical pathology, and histology were collected. These data were compared with those of 40 patients who underwent standard functional endoscopic sinus surgery in 2007. Statistically significant differences were found in terms of mean patient age, sex, mean number of sinuses surgically addressed, number of prior surgeries, and tissue eosinophil counts. Microscopic examination revealed the presence of "necrotic bone" in 2 Caldwell-Luc specimens, and "necrotic debris" in 2 other Caldwell-Luc specimens. No similar finding was seen in the control group. Caldwell-Luc is a surgery of last resort for patients who fail aggressive interventions for maxillary sinus disease. The mucosal lining of this small group of patients appears to be different from that of patients who respond favorably to functional endoscopic sinus surgery.     

Osteoma of the maxillary sinus

Osteomas of paranasal sinuses occur mainly in frontal and ethmoid sinus, in maxillary or sphenoid sinus are seen very rarely. The authors present a review of literature and next describe a case of spongioid osteoma in 42-years old female. The clinical features and radiologic assessment of the disease are presented. The tumour was resected by Caldwell-Luc operation with very good long term result.     

Isolated maxillary sinus Ewing's sarcoma

Extraskeletal Ewing's sarcoma is rarely found arising in the head and neck region. Only six cases of extraskeletal Ewing's sarcoma invading the nasal cavity or paranasal sinuses have been reported in the literature. The first described case of that Ewing's sarcoma located in isolated maxillary sinus extending into the orbita without involving the nose is presented. A 16-year-old woman presented with swelling in her right cheek. The nasal examination was normal. A computed tomography (CT) and magnetic resonance imaging (MRI) of the sinuses revealed a large mass in the right maxillary sinus with extension to the orbita. Under general anesthesia biopsies were taken. Based on histopathological analysis, a diagnosis of extraskeletal Ewing's sarcoma was made. The patient did not accept the surgical therapy. The patient was treated with combined chemotherapy and radiotherapy. The patient has done without evidence of recurrence or metastasis for one year.
