Introduction Pneumosinus dilatans (PSD) is a rare phenomenon involving the expansion of the paranasal sinuses, without bony destruction or a mass. Previously documented cases have demonstrated simple expansion of a solitary air cell. We present two unique cases of PSD in the presence of meningioma, in which complex new cells developed within the frontal sinus. One of the two patients developed associated sinus disease. Case 1 A 28-year-old man presented with facial pain. A computed tomography scan showed an abnormally enlarged, septated right frontal sinus, not present on childhood scans. He underwent a modified endoscopic Lothrop approach to divide the septations, and his symptoms resolved. Case 2 A 72-year-old woman presented with a 3-month history of headaches. Scans revealed a left frontal meningioma and multiple enlarged, dilated left frontal air cells. She had no clinical sinusitis and therefore was managed conservatively. Conclusions PSD has been widely documented in association with fibrous dysplasia and meningioma. The most prevalent theory of the mechanism of PSD is of obstruction of the sinus ostium causing sinus expansion through a “ball-valve” effect. Our cases, which demonstrate septated PSD, suggest a more complex process involving local mediators and highlight the need to consider underlying meningioma in pneumosinus dilatans.

Agger nasi cells contribute to nasofrontal duct (NFD) obstruction and chronic frontal sinus disease. To investigate this relationship, we conducted a review of the surgical outcome and computed tomographic imaging in 26 patients with chronic frontal sinusitis. Coronal and sagittal images were used to delineate the anatomic variability and mucosal disease in the NFD and frontal sinus region. Data from coronal and sagittal images were compared. The results were also correlated with the outcome of frontal sinus surgery in patients with a clinical history of chronic frontal sinus disease. Our data suggest that agger nasi cell pneumatization with narrowing of the frontal sinus outflow tract is a significant cause of persistent frontoethmoid pain and chronic frontal sinusitis. Sagittal reformatted images are more capable than coronal images of demonstrating agger nasi cell encroachment on the NFD, as well as NFD mucosal disease. Endoscopic frontal sinusotomy is an effective treatment for chronic frontal sinus disease.

Objective. Determining the indications for osteoplastic frontal sinus obliteration (OFSO) for the treatment of inflammatory frontal sinus disease.Study Design. Retrospective case series from a single tertiary care facility.Methods. Thirty-four patients who underwent OFSO for chronic frontal sinusitis () and frontal sinus mucocele () comprised our study group. Data reviewed included demographics, history of prior frontal sinus operation(s), imaging, diagnosis, and operative complications.Results. The age range was 19 to 76 years. Seventy percent of patients with chronic frontal sinusitis underwent OFSO as a salvage surgery after previous frontal sinus surgery failures, while 30% underwent OFSO as a primary surgery. For those in whom OFSO was a salvage procedure, the failed surgeries were endoscopic approaches to the frontal sinus (69%), Lynch procedure (12%), and OFSO outside this study period (19%). For patients with frontal sinus mucocele, 72% had OFSO as a first-line surgery. Within the total study population, 15% of patients presented for OFSO with history of prior obliteration, with a range of 3 to 30 years between representations.Conclusions. Osteoplastic frontal sinus obliteration remains a key surgical treatment for chronic inflammatory frontal sinus disease both as a salvage procedure and first-line surgical therapy.

History Of

We report a rare case of an extramedullary plasmacytoma (EMP) in the frontal sinus with an indolent clinical presentation. Although a history of trauma was absent, the initial diagnosis was a mucocele, based on the radiological findings. Upon surgical excision, the patient was found to have an EMP. EMP, a form of solitary plasmacytoma, has a significantly high rate of conversion to multiple myeloma. This mandates long-term follow-up, even after successful radiotherapy and/or resection. While radiation therapy is generally considered a first line treatment for EMP, surgical intervention may provide optimal treatment in complicated cases. This case presentation highlights the prognosis of patients diagnosed with EMP.

The Old City of Aleppo, a UNESCO World Cultural Heritage site, a living town of 110,000 inhabitants residing in thousands of historical courtyard houses and an important commercial centre is now the subject of an internationally recognized rehabilitation scheme. This paper describes the history of this project and identifies a series of lessons to be learnt about the complex process of rehabilitation in a living historic environment.

AbstractThe star formation history of galaxies is a complex process usually considered to be stochastic in nature, for which we can only give average descriptions such as the color-density relation. In this work we follow star-forming gas particles in a hydrodynamical N-body simulation back in time in order to study their initial spatial configuration. By keeping record of the time when a gas particle started forming stars we can produce Lagrangian gas-star isochrone surfaces delineating the surfaces of accreting gas that begin producing stars at different times. These surfaces form a complex a network of filaments in Eulerian space from which galaxies accrete cold gas. Lagrangian accretion surfaces are closely packed inside dense regions, intersecting each other, and as a result galaxies inside proto-clusters stop accreting gas early, naturally explaining the color dependence on density. The process described here has a purely gravitational / geometrical origin, arguably operating at a more fundamental level than complex processes such as AGN and supernovae, and providing a conceptual origin for the color-density relation.

Although osteogenic sarcoma occurs in the head and neck, it is almost exclusively limited to the maxilla and the mandible. Single, rare cases of this tumor in other facial bones are mentioned in foreign reports, but a discussion in the English literature has not come to our attention. The case history of a 58-year-old woman with a nonspecific frontal sinus pain and right-sided proptosis is presented. Plain radiographs of the paranasal sinuses revealed a radiopaque, calcific mass in the right frontal sinus approximately 3 × 5 cm in diameter. It was noted that the mass had an “onionskin” lamination. Laminography aided in the exact localization of the mass; further, it was noted on arteriography that the frontal sinus mass did not invade the dura. A frozen section biopsy at the time of craniotomy suggested a benign histologic lesion. However, subsequent review of permanent sections showed findings typical of an osteogenic sarcoma. The patient was treated with irradiation and in the first postoperative year has done well.

The objective of this study is to present the use of surgical navigation in the selective removal of the anterior table of the frontal sinus in a patient with pneumosinus dilatans. A 16-year-old boy presented with progressive deformity of the forehead and left postauricular sulcus due to pneumosinus dilatans. Reconstruction of the anterior table of the frontal bone was assisted by a surgical navigation system that used data from a preoperative computed tomography scan of the head and neck to map out the boundaries of the frontal sinus. The device enabled selective resection of the anterior table without violation of the cranial cavity.
