A sinus pneumocele is a rare entity caused by obstruction of a paranasal sinus ostium. It is characterised by dilation and expansion of the sinus, with subsequent bony erosion. The most probable mechanism is air trapping in the paranasal sinus, via a one-way valve mechanism. The case presented concerns a 68-year-old Caucasian man, with recurrent episodes of acute rhinosinusitis. Clinical examination and subsequent imaging of the face, revealed a large pneumocele of the right frontal sinus that significantly eroded the posterior sinus wall. A large mucocele of the right maxillary sinus was also noted, extending to the middle meatus, causing full obstruction of the ostiomeatal complex. Endoscopic sinus surgery was performed, the mucocele was removed and the pneumatisation pathway of the frontal sinus was restored. The patient reports full resolution of symptoms and shows no evidence of recurrence, 6 months postoperatively.

Ameloblastoma (AM) in the maxillary sinus is rare. This benign entity shows locally invasive, destructive and aggressive behaviour and a high rate of recurrence. Therefore, the course of treatment is radical resection. We report the case of a 38-year-old man presenting with signs of recurrent sinusitis in the Ear, Nose and Throat Department. Transnasal flexible endoscopy revealed a cystic mass in the right inferior and middle nasal passage. CT scan showed an obliterated right maxillary sinus with a ballooning effect and pressure atrophy of the lateral sinus wall, without possible differentiation of the middle and low nasal turbinate. The patient was treated with transnasal functional sinus surgery; pathology stated AM. AM in the maxillary sinus is rare, locally destructive and therefore as a gold standard is resected radically to prevent recurrence. We demonstrate a conservative approach; explicitly, we combined a transvestibular and functional endoscopic sinus surgery resection of the AM to maintain function and reduce the possibility of postoperative impairments. Whether the strategy of treatment for AM is conservative, it nonetheless can result in a recurrence-free status. Nevertheless, inclusion into an oncological follow-up-programme with regularly performed MRI and CT is recommended.

Orbital emphysema is a benign self-limiting condition. It can occur directly (as a result of trauma to the face) or indirectly (secondary to a blowout fracture). We report a case of orbital emphysema in a 38-year-old man who presented with ecchymosis of the right eye, pressure within the right orbit, and periorbital swelling following a protracted episode of vigorous sneezing. The diagnosis was confirmed by computed tomography. Systemic antibiotics were given, and the patient was cautioned to avoid blowing his nose. His signs and symptoms resolved within 1 week.

Introduction. Silent sinus syndrome is a rare condition, characterized by spontaneous and progressive enophthalmos and hypoglobus associated with atelectasis of the maxillary sinus and downward displacement of the orbital floor. Patients with this syndrome present with ophthalmological complaints, without any nasal or sinus symptoms. Silent sinus syndrome has a painless course and slow development. It seems to be a consequence of maxillary sinus hypoventilation due to obstruction of the ostiomeatal unit. The CT scan findings are typical and definitely confirm the diagnosis of silent sinus syndrome. Case report. We present the case of a 35-year-old woman, with no history of orbital trauma or surgery. She had slight righthemifacial pressure with no sinonasal symptoms. The patient had no double vision nor other ophthalmological symptoms. The diagnosis of silent sinus syndrome was based on the gradual onset of enophthalmos and hypoglobus, in the absence of orbital trauma (including surgery) or prior symptoms of sinus disease. On paranasal CT scans there was a complete opacification and atelectasis of the right maxillary sinus with downward bowing of the orbital floor. The patient was treated with functional endoscopic sinus surgery, with no orbital repair. Conclusion. Silent sinus syndrome presents with orbithopaties but is in fact a rhinologic disease, so all ophthalmologists, rhinologists and radiologists should know about it. The treatment of choice for silent sinus syndrome is functional endoscopic sinus surgery, which should be performed with extra care, by an experienced rhinosurgeon.

Background The aim of this study was to evaluate effects of functional endoscopic sinus surgery (FESS) on transient nasal aerodynamic flow patterns using computational fluid dynamics (CFD) simulations. Methods A three-dimensional model of the nasal cavity was constructed from CT scans of a patient with FESS interventions on the right side of the nasal cavity. CFD simulations were then performed for unsteady aerodynamic flow modeling inside the nasal cavity as well as the sinuses. Results Comparisons of the local velocity magnitude and streamline distributions inside the left and right nasal cavity and maxillary sinus regions were presented. Because of the FESS procedures in the right nasal cavity, existences and distributions of local circulations (vortexes) were found to be significantly different for the same nasal airflow rate but at different acceleration, deceleration, or quiet phases in the maxillary sinus region on the FESS side. Because of inertia effects, local internal airflow with circulation existences was continuous throughout the whole respiration cycle. With a larger peak inspiration flow rate, the airflow intensity inside the enlarged maxillary sinus increased significantly. Possible outcomes on functional performances of the nose were also examined and discussed. Conclusion Surgical enlargements of natural ostium of the maxillary sinus will change the aerodynamic patterns inside the main nasal cavity and maxillary sinus regions, which may affect normal nasal physiological functions. Local inertia effects play more important roles for the internal nasal airflow pattern changes and thus such conventional FESS procedures should be carefully planned.

Bone Abnormalities

Abnormalities of the underlying bone of the paranasal sinuses have sometimes been shown in Wegener’s granulomatosis (WG). We describe an interesting case of WG with extensive bone abnormalities in the sinuses mimicking fungal sinusitis. A 30-year-old woman presented with intermittent unilateral epistaxis. Biopsy was performed for the granulation tissue in the right nasal cavity, and she was diagnosed as having WG. Computed tomography (CT) revealed a ring-like calcification, mimicking a fungus ball, in the right maxillary sinus. Endoscopic sinus surgery was performed to confirm the diagnosis. A spherical bony structure, surrounded by granulation tissue, was identified in the maxillary sinus. The wall of the “bony ball” was fragile, like an egg shell. No fungus was found in the sinus. Thus, the extensive bone abnormalities were due to WG.

Maxillary sinus squamous cell carcinoma is an invasive tumour that is usually diagnosed at an advanced stage, where the majority of patients have a very low prognosis and survival rate. We present a case of maxillary sinus carcinoma that affected the entire orbit, resulting in proptosis of the eye and nasal cavity. The patient was recommended for palliative treatment due to the high degree of its involvement and proximity to vital structures. It manifests with very mild to no signs, resulting in a late diagnosis. As a result, physicians must be mindful of maxillary sinus pathologies to make an early diagnosis. Paranasal sinuses are air-filled spaces located close to vital structures such as visual organs and the face. Maxillary, ethmoidal, frontal, and sphenoidal are the 4 paranasal sinuses that are named according to the bones in which they are situated. Nasal cavity and paranasal air sinus malignancies are uncommon. According to the literature, paranasal sinus malignancies account for less than 1 % of all human malignancies and 3 % of the total malignancies of the head and neck region. However, the maxillary sinus is the most frequent site of origin of primary malignant tumours amongst the paranasal sinuses.1 we need to raise general awareness among the oral stomatologists as Asian countries report a very high incidence of maxillary sinus carcinoma.2 The incidence of malignancies in maxillary sinus is high (60 % - 70 %) and less in the nasal cavity (12 % - 25 %), the Ethmoid (10 % - 15 %) and very rare in sphenoid / frontal sinuses (1 %).3 Further, not only the malignancies of maxillary sinuses are common, but they also incur the worst prognosis. Maxillary sinus carcinomas have very few symptoms and are similar to those of chronic paranasal sinusitis. They usually present themselves as locally advanced diseases. 4,5 Paranasal sinus malignancies are difficult to diagnose in the early stages and 90 % of cases are reported in T3 / T4 advanced stage.6 Environmental factors such as industrial pollutants, dust, smoke, and adhesives are the leading causes for the development of disease.7 Thus, sinonasal malignant tumours are rare and pose a challenge in diagnosis as well as treatment. Therefore, maxillofacial specialists should be aware of the signs and symptoms of this rarely occurring disease. This article presents a rare case of a 45-year-old female who reported to our OPD with a complaint of swelling in the right zygomatic area and proptosis of the right eye.

OBJECTIVE: To evaluate change of the maxillary sinus volume according to patient age and gender by using a 3-dimensional (3-D) reconstruction of computed tomography images. STUDY DESIGN AND SETTING: One hundred seventy-three people (totaling 238 maxillary sinuses) who had undergone paranasal sinus CT scan between December 2000 and November 2003 and had no evidence of inflammation or hypoplasia in the CT finding and had no specific history of paranasal sinus surgery or maxillofacial trauma were retrospectively analyzed. The 3-D reconstruction images were obtained by using a surface-rendering technique (Vworks; CybeMed, Seoul, Korea) on a personal computer. The mean volume of maxillary sinus was evaluated according to patient chronologic age and gender. The ratio of the maximum horizontal and half-horizontal extension for the estimation of the morphological change of maxillary sinus and the degree of descent of the sinus below the nasal floor were evaluated in the 3-D image. RESULTS: The development of the maxillary sinus continued until the 3rd decade in males and until the 2nd decade in females. The mean maxillary sinus volume in early adults was 24,043 mm 3 (males) and 15,859.5 mm 3 (females). There was a significance difference in the sinus volume ( P < 0.05) according to gender, and there was a significant difference in the maxillary sinus volume according to age before it reached maximum. After its maximum growth period, however, there was no significant difference in the volume change of maxillary sinus and the descent below the nasal floor between two adjacent groups. CONCLUSIONS: The growth of the maxillary sinus continues until the 3rd decade in males and the 2nd decade in females. Therefore, a maxillary sinus operation affecting the bony structures before these ages might affect the development of the sinus and needs to be performed carefully

Importance: Safe entry into sphenoid sinus is critical in endoscopic sinus and skull base surgery. A number of surgical landmarks have been used to identify the sphenoid sinus ostium during endoscopic endonasal surgery with variable reliability and intraoperative feasibility. Objective: To determine if the posterior wall of the maxillary sinus is a reliable landmark to determine the depth of the sphenoid sinus ostium during anterior to posterior dissection. Design, Setting, and Participants: Prospective study of adult patients undergoing endoscopic sinus surgery between August 2016 and September 2017. Measurements were made intraoperatively between the depth of the posterior maxillary sinus wall and sphenoid sinus ostium. Main Outcomes and Measures: The primary measurement is the distance between the depth of the posterior maxillary sinus wall and sphenoid sinus ostium. Additional data points included age, gender, surgical indication, and primary versus revision endoscopic sinus surgery. Results: Forty-five patients (38% male, 62% female) with an average age of 56 were enrolled, resulting in 88 operated sides. The average distance between the depth of the posterior wall of the maxillary sinus and the sphenoid ostium was 1.5 mm ± 1.4 mm. The most common position of the sphenoid sinus ostium was posterior to the level of the posterior maxillary sinus wall (54%), followed by same level (23%) and anterior (23%). There was no significant difference between different disease states ( P = .75) and between primary and revision cases ( P = .13). Conclusions and Relevance: The posterior wall of the maxillary sinus serves as an adjunctive intraoperative landmark to determine the depth of the sphenoid sinus ostium. While the posterior wall of the maxillary sinus approximates the depth of the sphenoid sinus ostium, the relative position is variable and can be anterior or posterior.

Fluid Leak

Frontal sinus stenting is widely used with the goal of maintaining nasofrontal duct patency after sinus surgery. The general recommendation is to leave stents in place for 6 months; however, prolonged stenting up to 6 years has been reported with no complication. We present the first reported case of frontal sinus posterior table and skull base erosion following prolonged frontal sinus stenting. A 57-year-old female presented with chronic sinusitis and nasal obstruction. Imaging revealed pansinusitis with retained stents in each frontal sinus that were placed 8 years prior. On the right, there was an area of skull base erosion at the tip of the stent. The patient underwent functional endoscopic sinus surgery with polypectomy. The stents were removed, revealing posterior table erosion on the right side but intact mucosa. Two months after surgery, there were no signs or symptoms of cerebrospinal fluid leak or other complications. Recent literature has suggested that prolonged stenting is safe; however, this case highlights a complication with potentially serious outcomes that can result from prolonged stenting. We recommend stent removal once stable nasofrontal duct patency has been achieved. If prolonged stenting is utilized, patients should be closely monitored and consideration should be given to periodic imaging to evaluate stent position.
