Transnasal Marsupialization Using Endoscopic Sinus Surgery for Treatment of Keratocystic Odontogenic Tumor in Maxillary Sinus

Objective.We report the first utilisation of transnasal marsupialization to treat a keratocystic odontogenic tumor in the maxillary sinus of a 37-year-old man.Case Report.A 37-year-old man presented with a nasal discharge and right odontalgia. Computed tomography revealed an expanding cystic lesion with a calcificated wall containing an impacted tooth in the right maxillary sinus. The diagnosis was keratocystic odontogenic tumor. Transnasal marsupialization was performed using endoscopic sinus surgery to enlarge the maxillary ostium and remove a portion of the cystic wall. Pathological findings included lining squamous epithelium and inflammation. The remaining tumor shrank, becoming free of infection after surgery, without proliferation.Conclusion.Transnasal marsupialization using endoscopic sinus surgery is effective in treating keratocystic odontogenic tumors. It offers minimal surgical invasion and reductive change, making it advantageous for complete removal with fewer complications in the bones and surrounding tissue in the case of secondary surgery.

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.

ABSTRACT Antrorhinolith is an uncommon nasal mineralized mass of nasal cavity invading into maxillary sinus. Most antrorhinoliths are small and asymptomatic, caused by calcification of a nidus and are detected incidentally on radiological examination. Sometimes they present symptoms like pain and foul smelling nasal discharge. Here, we are presenting two cases of antrorhinoliths. One was found after endoscopic sinus surgery and second one was seen in patient with prolonged use of topiramate medication. In all these two cases, radiological examination revealed a discrete bony density in the nasal cavity and maxillary sinus which was blocking the ostiomeatal complex. The bony mass was removed endoscopically from the nasal cavity and maxillary sinus with drainage of discharge and debris from the sinuses. Histopathological examination revealed an antrolith with bony nidus and calcium deposited around it. How to cite this article Swain SK, Sahoo RK, Sahu MC. Two Case Reports of Antrorhinoliths.

AbstractBackground:Intranasal medication is commonly used for nasal disease. However, there are no clear specifications for intranasal medication delivery after functional endoscopic sinus surgery.Methods:A three-dimensional model of the nasal cavity was constructed from computed tomography scans of an adult Chinese male who had previously undergone functional endoscopic sinus surgery in the right nasal cavity. Computational fluid dynamic simulations modelled airflow and particle deposition, based on discrete phase models.Results:In the right nasal cavity, more particles passed through the upper dorsal region, around the surgical area, and streamed into the right maxillary sinus region. In the left cavity, particles were distributed more regularly and uniformly in the ventral region around the inferior turbinate. A lower inspiratory airflow rate and smaller initial particle velocity assisted particle deposition within the right maxillary sinus cavity. In the right nasal cavity, the optimal particle diameter was approximately 10−5 m for maxillary sinus cavity deposition and 3 × 10−6 m for bottom region deposition. In the right nasal cavity, altered back head tilt angles enhanced particle deposition in the top region of the surgical area, and altered right side head tilt angles helped enhance maxillary sinus cavity deposition.Conclusion:This model indicates that a moderate inspiratory airflow rate and a particle diameter of approximately 10−5 m should improve intranasal medication deposition into the maxillary sinus cavity following functional endoscopic sinus surgery.

Csf Leaks

Cerebrospinal fluid (CSF) leaks associated with endoscopic sinus surgery (ESS) are a rare complication affecting approximately 0.09% of patients. Although meningitis is a well-known complication of CSF leaks, the case we present is a rare and cautionary case of CSF leakage associated with ESS leading to aspiration pneumonia. A 43-year-old man with CSF leaks after ESS was referred to our hospital. After the operation, sometimes, he reported having a serous nasal discharge from the right side when he bent over, and he woke up choking on something every day. He also experienced headache, fever, fatigue, and cough. Interestingly, chest computed tomography (CT) showed a consolidation and ground-glass opacity in the posterior segments of the right upper lobes and superior segments of the bilateral lower lobes. These CT imaging findings were similar to those of aspiration pneumonia in bedridden patients who are always in a supine position. These findings suggest that CSF caused aspiration pneumonia. To the best of our knowledge, no case of aspiration pneumonia caused by CSF during endoscopic sinus surgery has been reported until now. If a patient with CSF leakage after ESS experiences fever, cough, or fatigue, physicians should consider aspiration pneumonia in addition to meningitis.

We present a case of maxillary sinusitis caused bySchizophyllum commune, in a 50-year-old female. The patient presented with nasal obstruction, purulent nasal discharge from right side of the nose, cough, headache, and sneezing. Computed tomography revealed extensive opacity of the right maxillary sinus as well as erosion of the nasal wall and maxillary bone. Functional endoscopic sinus surgery was done, and fungal debris present on right side of the maxillary sinus was removed and sent to laboratory. Potassium hydroxide (KOH) examination of the nasal discharge showed hyaline, septate hyphae. Primary isolation on Sabouraud's dextrose agar (SDA) yielded a white woolly mould. Banana peel culture after 8 weeks showed macroscopically visible fan-shaped fruiting bodies. Lactophenol cotton blue (LPCB) mount of the same revealed hyaline septate hyphae, often with clamp connections. Identification was confirmed by the presence of clamp connections formed on the hyphae and by vegetative compatibility with known isolates.

Adenomatoid odontogenic tumor (AOT) is a benign, slow-growing lesion and it is considered the fourth most common odontogenic tumor. AOT affects more frequently the young subjects with a predilection for the second and third decades of life. We present here the case of a 36-year-old man affected by large extrafollicular AOT which caused roots resorption of multiple teeth. The lesion involved the entire right maxillary bone and extended into the right maxillary sinus up to the orbital floor and the nasal cavity. Intra-oral surgical excision of the AOT and functional endoscopic sinus surgery led to complete clinical healing in absence of local recurrences.
