The purpose of this work was to present an anatomic reference for computed tomography (CT) for the paranasal sinuses of adult buffalo fit the use of anatomists, radiologists, clinicians and veterinary students. CT images with the most closely corresponding cross sections of the head were selected and studied serially in a rostral to caudal progression from the level of the interdental space to ...

OBJECTIVE To evaluate the effectiveness of endoscopic cauterization as definitive treatment for fourth branchial cleft sinuses. DESIGN Retrospective chart review with follow-up questionnaire. SETTING Tertiary care children's hospital. PATIENTS Ten children (age range, 10 months to 10 years) with fourth branchial cleft sinuses treated with endoscopic cauterization between 1995 and 2002. ...

BACKGROUND Although the determinates of paranasal sinus development and sinusitis are not well defined, a candidate factor is blockage of the choana. HYPOTHESIS Maxillary sinuses ipsilateral to unilateral choanal atresia are comparatively small and have more evidence of sinusitis than do the contralateral sinuses. DESIGN Retrospective. SETTING Children's hospitals. PATIENTS Sixteen nons...

Modern medical advances allow us to expand a range of combined surgical interventions. The literature this day does not cover issues regarding the implementation typical options for operations with deformities nasal septum, structures lateral wall cavity, nose, pathological processes in hole paranasal sinuses; perforated odontogenic maxillary sinusitis; racemose, sprains sinuses, damage orbit. ...

BACKGROUND AND PURPOSE The crista galli is part of the ethmoid bone and, as such, it could be expected that aeration of the crista would come from ethmoid cells. After observing crista pneumatization from the frontal sinuses in several cases, we undertook this study to establish how often crista galli pneumatization came from the frontal sinuses rather than from the ethmoid complex. MATERIALS...

BACKGROUND Breast cancer can very rarely result in late metastases to the paranasal sinuses. METHODS AND RESULTS We present a 75-year-old woman who developed sinonasal symptoms mimicking sinusitis 20 years after receiving a breast cancer diagnosis. Rigid nasendoscopy was unremarkable, but due to persistent unilateral nasal symptoms and suspicious radiological findings, the patient underwent e...

INTRODUCTION The sinonasal malignant tumors are rare, representing less than 3% of the cervicofacialneoplasma and 0.8% of all human cancers. Approximately 55% have their origin in the maxillary sinuses, 35% in the nasal cavity, 9% in the ethmoid sinuses and 1% in the frontal and sphenoid sinuses. The malignant sinonasal tumors affect less than 1 person out of 100,000 individuals per year in mos...

Transsphenoidal surgery produces changes in the parana sal sinuses and sella that should be familiar to radiologists in view of the frequency of this type of surgery. Some of these changes, such as soft-tissue-density debris in the sinuses, are transient. Fat and other packing material identifiable in the sinuses and sella after surgery is permanent. The procedure is associated with a variety o...

Introduction: Mucoceles of the paranasal sinuses are relatively rare. A very busy otolaryngology department does not have more than a few cases each year. Bilateral, multiple, and multiloculated cases are extremely unusual. Case Presentation: We report a 74-year-old man with two separate mucoceles in left ethmoid and frontal sinuses with pansinusitis. After marsupialization of mucoceles and fun...

An otorhinolaryngologist must know the anatomy of nasal cavity and paranasal sinuses prior to endoscopic surgery, because many structures cann’t be evaluated by him during visual examination. In this regard, all patients undergo computed tomography as a preoperative preparation, which allows not only identify pathological process, but also assess anatomical features that may predispose surgical...
