BACKGROUND: Lung transplantation has revolutionized the treatment of end-stage pulmonary disease due to cystic fibrosis. However, infection of the transplanted lungs can lead to serious complications, including graft failure and death. Although many of these patients have concurrent sinusitis, it is unclear whether bacteria from the sinuses can infect the allograft. METHODS: This is a single-institution retrospective study of all patients who underwent lung transplantation for cystic fibrosis from 2005 to 2015 at Duke University Hospital...

The endoscope has revolutionized the diagnosis and treatment of diseases of the nose and paranasal sinuses. Endoscopic sinus surgery (ESS), like all minimally invasive surgery, is designed to combine an excellent outcome with minimal patient discomfort. Successful outcome with minimal complications can only be achieved with good knowledge of the endoscopic anatomy, appropriate training in the procedure and the understanding of the anatomical variations. The intraoperative complications of ESS are bleeding and injury to surrounding structures commonly the orbital structures and fovea ethmoidalis...

Transitioning of rhinologic procedures from the operating room to the office setting in selected patients is a rising trend. An effective pain-control, patient-preparation protocol is essential, especially with advanced in-office rhinologic procedures such as hybrid balloon sinus dilation (BSD), in which other procedures such as ethmoidectomy, turbinate reduction, and other procedures are concomitantly performed. A regimen using oral sedation, topical tetracaine gel, topical tetracaine/epinephrine-soaked cottonoid packs, and intranasal local infiltrative anesthesia can vary significantly in effectiveness and be suboptimal at times (as determined by using treated patients as historical controls)...

Nasal polyposis (NP) is an inflammatory disease of the paranasal sinuses and nasal cavity. The primary purpose of our study is to determine the expression of 5-HT7 receptors both in nasal polyps and in healthy tissue in the nasal cavity. The subsequent aim is to compare the expression of 5-HT7 receptors in patients with NP and in inferior turbinate tissue (control). The study included 60 participants (40 with NP and 20 controls) aged 35 to 62 years. Nasal polyp samples were collected from all patients and relative 5-HT7 receptor expression analyses were performed...

Mucoceles of the paranasal sinus can be managed endoscopically with an extremely low recurrence rate. Frontal sinus mucoceles can sometimes be prevented from closing and reforming by stenting, which to the best of our knowledge has not yet been reported in the maxillary sinus. We describe the cases of 5 patients-3 men and 2 women, aged 47 to 75 years (mean: 59.6)-with a recurrent and intractable maxillary sinus mucocele that was managed with biliary T-tube stenting. The indications for stenting included recurrent episodes of mucocele with or without a lateral location with a relatively thick bony wall...

Objective: The aim of this paper is to report on a case of positive human identification of a decomposed body after the comparison of ante-mortem (AM) and port-mortem (PM) computed tomography images of frontal sinus. Case report: An unknown, highly decomposed human body, aged between 30 and 40 years, was found in a forest region in Brazil. The dental autopsy revealed several teeth missing AM and the presence of removable partial prostheses. The search for AM data resulted in a sequence of 20 axial images of the paranasal sinuses obtained by Multislice Computed Tomography (MSCT)...

Fucosidosis is an autosomal recessive lysosomal storage disorder caused by the deficiency of alpha-L-fucosidase. We present the case of an affected female in the second decade of life with chronic rhinosinusitis (CRS) including recalcitrant polypoid inflammation, which has not been previously reported in the literature. With the advancement of life-prolonging measures, children with lysosomal storage disorders may suffer increasingly from CRS due to the lymphohistiocytic and macrophage infiltrate of the paranasal sinus mucosa that resembles severe polypoid inflammation...

Aneurysmal bone cysts (ABCs) mostly occur in the metaphysis of long bones. Primary paranasal ABCs are extremely rare and most reported cases reveal typical histopathological features including cystic space with fibrous septa and hemorrhage. Solid variant ABCs or solid ABCs lacking cyst formation may be histologically indistinguishable from giant cell reparative granulomas (GCRGs), giant cell tumor of bone (GCTB), and brown tumor. Here we report the case of a 24-year-old female with a paranasal mass diagnosed as USP6-rearranged solid ABC, mimicking GCRG, GCTB and brown tumor...

Hemangiomas are benign tumors originating from the skin, mucosa, muscle, gland, and vascular tissue in the bone. Although it is common in the head and neck region, it is rarely seen in the nasal cavity and paranasal sinuses. Histologically capillary, cavernous, and mixed types are present, the most common is cavernous-type hemangioma. Cavernous hemangiomas in the nasal cavity, generally originated from the lateral nasal wall, cause symptoms as nasal obstruction and epistaxis. In the author's patient, cavernous hemangioma was originated from the nasal septum, where rarely seen...

Malignancies of the nasal cavity and paranasal sinuses account for 1% of all malignancies and 3% of malignancies of the upper aerodigestive tract. In the sinonasal tract, nearly half of all malignancies arise in the nasal cavity, whereas most of the remaining malignancies arise in the maxillary or ethmoid sinus. Squamous cell carcinoma is the most common histological subtype of malignant tumors occurring in this area, followed by other epithelial carcinomas, lymphomas, and malignant soft tissue tumors. Although many of these tumors present with nonspecific symptoms, each tumor exhibits characteristic imaging features...

Background: Mucociliary clearance is the main self-clearing system of the nasal cavity and paranasal sinuses.This is a very important means of non specific defence against continuous organic and inorganic contamination conveyed by air. It works by trapping particles and microorganisms in the mucus and then by transporting the mucous film to the pharynx where it is eliminated with a cough or swallowed. Its congenital or acquired abnormalities are involved in the occurrence of widespread infectious and often severe nose and paranasal sinuses diseases; generally concerning the rhinopharyngealtubal district...

Background: Displacement of dental implants into the maxillary sinus is rare, but it primarily occurs in patients with severe pneumatization of the maxillary sinus and/or deficiency of the alveolar process. Some complications such as the infection of the paranasal sinuses and formation of the oroantral fistula can be followed by the displacement of a dental implant. Therefore, the displaced implant has to be removed immediately with surgical intervention show and another plan for rehabilitation should be considered...

Rhinosinusitis is one of the most common inflammatory conditions of the nasal cavity and paranasal sinuses and is one of the most common causes of absence from work and for visits to the family doctor. The treatment strategy in both acute rhinosinusitis (ARS) and chronic rhinosinusitis (CRS) is to reduce the severity of the symptoms, minimize the duration of the disease and prevent complications. Topical therapy has become an important tool in otolaryngologistsÂ’ armamentarium for rhinosinusitis treatment. Recently, topical hyaluronic acid (HA), the major component of many extracellular matrices that promotes tissue healing, including activation and moderation of the inflammatory responses, cell proliferation, migration and angiogenesis, has been proposed for ARS and CRS adjuvant tool...

Rosai-Dorfman disease, also known as sinus histiocytosis with massive lymphadenopathy is a rare non-Langerhans' cell histiocytic disease resulting from the proliferation and accumulation of sinus histiocytes within lymph nodes. Extranodal involvement frequently occurs, which increases the morbidity and mortality of the disease. There is no clear consensus with regard to the most effective diagnostic and treatment modalities. This report will focus on the diagnostic imaging, treatment, and outcomes for 3 cases of Rosai-Dorfman disease...
