Pleomorphic adenoma (PA) of nasopharynx is very rare. Squamous metaplasia of PA is an unusual finding and has the possibility for misdiagnosis as squamous cell carcinoma (SCC). This study presents two cases of nasopharyngeal PA diagnosed as SCC from frozen sections, whereas permanent pathology was PA with squamous metaplasia. Preoperative endoscopy, radiographic images, and histopathological findings were reviewed. Two male patients underwent complete en-bloc resection of tumors with adequate margins because of the possibility of SCC from frozen section. The pathologic results were PA with squamous metaplasia and there was no recurrence during one year follow-up period. Nasopharyngeal PA can mimic SCC, surgeons should consider the clinical and radiological characteristics of tumors. We do not recommend deciding treatment modalities for nasopharyngeal tumors with only the frozen section.

Endoscopic skull base surgery is a rapidly growing surgical area with collaboration of otolaryngology-head and neck surgeons and neurosurgeons. Various tumor pathology and extent have been successfully treated with endoscopic transsphenoidal approach and diverse reconstruction methods have been adopted since its introduction. Optimal reconstructive strategy should be properly selected with the consideration of the heterogeneous surgical situations and tumor extent. Nevertheless, there are no current manuals in selecting when and how. Therefore, we sought to review diverse options of sellar floor reconstruction.

Background : Endoscope has improved dramatically and is currently utilized in all fields of neurosurgery. In particular, endoscope is widely used in skull base surgery. However, endoscope possesses innate limitation in which it should be operated manually. To overcome this problem, robotic holding system has been developed and its use is gradually expanding. Methods : Fifty cases in single institution from October to November, 2019 that underwent surgery with assistance by ENDOFIXexo (AKTORmed, Barbing, Germany) were analyzed to evaluate the effectiveness of robotic holding system. All operations were performed by the corresponding author. Results : Total 47 patients underwent operation and 50 cases, including 3 revisions due to cerebrospinal fluid leakage, were reviewed. The histological diagnoses included 35 pituitary adenomas, 7 meningiomas, 2 Rathke’s cleft cysts, 2 craniopharyngiomas, and 1 cavernous hemangioma. No severe or unexpected events such as swaying or fall down of robotic holding system were reported. Conclusions : ENDOFIXexo can be manipulated easily without any discomfort and no significant complications were found. From the study, we showed the effectiveness of the robotic holding system. Growing experience in using the robotic holding system will eventually accelerate the advance of the system and treatment outcome.

Epithelioid hemangioendothelioma is a rare vascular tumor usually occurs in soft tissue. It rarely occurs in nasal cavity and paranasal sinus. This tumor is potentially recurrent that radical surgical resection plays an important role for better management. There are limited cases of epithelioid hemangioendothelioma in nasal cavity especially invading skull base. In this report, we describe a 51-year-old female with recurrent epithelioid hemangioendothelioma in sinonasal cavity invading adjacent skull base.

Olfactory neuroblastoma is malignant tumors, which is rare to the sinonasal tract. This tumor is challenging to surgeon because it is difficult to achieve negative resection margin without causing facial disfigurement and loss of olfaction. There were few cases of craniofacial resection of this tumor with preservation of the olfaction. Therefore, we report a case of 34-year-old male who underwent endoscopic craniofacial resection for olfactory neuroblastoma with preserving olfactory function.

Acute invasive fungal sinusitis is an aggressive and often fatal infection. It is characterized by tissue invasion and can frequently spread beyond the paranasal sinuses. When fungal disease extends to the skull base, surgical debridement can be challenging. Traditionally, external approaches have been used for the management of disease in these areas. But recent advances in endoscopic skull base surgery have emerged as a successful surgical modality allowing for minimally invasive approaches with decreased morbidity and comparable treatment outcomes. We report our institution’s experience with endoscopic debridement of invasive fungal sinusitis extending beyond the skull base, safely performed with successful treatment outcome.

Organized hematoma is a rare non-neoplastic lesion causing bone destruction and obstruction. The exact mechanism remains unclear; it is known that tumors develop well when bleeding is poorly ventilated or drained. Compared to the maxillary sinus, the sphenoid sinus or ethmoid sinus have insufficient cavity to develop the organized hematoma. We report a case of 45-year-old male with organized hematoma in sphenoid and ethmoid sinus which was mimicking a malignant tumor. The patient had radiation therapy due to nasopharyngeal cancer. The computed tomography scan revealed an expansile neoplasm of ethmoid and sphenoid sinus, so we speculated it as recurrence of tumor. However, endoscopic deep biopsy proved that it was organized hematoma. Even if the tumor occurs in a relatively rare location, it is necessary to distinguish between malignant and benign tumor in consideration of the patient’s history and clinical features.

Invasive sphenoid fungal sinusitis sometimes invades the adjacent structures such as the optic nerve or cavernous sinus. Here, we present the treatment for a primarily embolized mycotic aneurysm that ruptured during endoscopic sinus surgery. This report describes the case of a 72-year-old man with a mycotic aneurysm. Although the patient’s mycotic aneurysm was controlled by coil embolization, the subsequent endoscopic surgery resulted in massive bleeding and dislocation of the embolic coil. The ruptured vessel was stably controlled by internal carotid artery occlusion. This case emphasizes the need for careful consideration when performing endoscopic surgery for sphenoid sinusitis in patients especially with a mycotic aneurysm.

Background and Objectives: Maxillectomy is the mainstay of treatment for malignant tumors of the maxillary sinus(MS). Nevertheless, few have been reported on the surgical outcomes of maxillectomy for malignant tumors of MS in Korean literature. Based on our clinical experience, the authors aimed to present the treatment outcomes of maxillectomy for squamous cell carcinomas(SCC) of MS. Subjects and Methods: We reviewed the medical records of 26 cases of maxillectomies with see of MS, who were treated from 1995 to 2004 at Samsung Medical Center. Most patients(73.1%) were locally advanced stage(T3 or T4a) at initial presentation. Total maxillectomy was performed in 18 cases, which is the most frequent procedure(69.2%). We analyzed the treatment outcomes of see of MS and several variables includeing tumor stage and resection margin to identify predictors for treatment failure after maxillectomy. Follow-up duration ranged from 7 to 89 months with a mean of 33 months. Results: Treatment failure occurred in 7 cases(26.9%), among which 3 were salvaged. Three of 26 maxillectomies(11.5%) showed the positive or close(less than 5mm) resection margin in their posterior resection sites; however it did not coincide with the site of recurrence after radiation therapy. Among patients who had been followed up for more than 6 months, disease-free 3 year survival rate was 100.0% in T1 and T2, 76.2% in T3, 60% in T4a, and 69.6% in total. Conclusion: Even though most of see of MS were detected at locally advanced stage, maxillectomy with or without postoperative radiation therapy for resectable MS see(T1-T4a) provided the acceptable treatment outcome(70%, 3Y disease-free survival rate).
