Objective and Patient Both nasal cerebral heterotopia and encephalocele are rare congenital benign masses of neurogenic origin caused by an embryonic developmental abnormality. It is generally accepted that nasal heterotopia is a sequelae to encephalocele. This report presents an unusual case of nasal cerebral heterotopia and encephalocele arising in the same patient. The patient had a firm, solid mass measuring 1.5 × 1.0 cm on the bridge of the nose covered with normal skin and another mass in the nasal cavity obstructing the right nasal cavity. Computed tomography (CT) demonstrated that the nasal bone separated these masses. CT also showed a bony defect at the skull base. Surgery consisted of dividing the encephalocele and closure of the skull base fistulae, along with nasal subcutaneous mass enucleation. Results Intraoperative examination indicated the existence of a pit on the nasal bone where the pedicle of the nasal subcutaneous mass connected. Microscopic examination of the nasal cavity mass demonstrated meningoencephalocele, and examination of the nasal subcutaneous mass demonstrated nasal cerebral heterotopia, which was confirmed by immunohistochemical staining. After 10 months, complete removal of the subcutaneous nasal mass was recognized and there was no evidence of recurrence. Conclusion Findings in this case suggest that the nasal cerebral heterotopias will result from encephalocele.

AbstractWe present an unusual case of generalized erosion of the skull base. We have not found a similar case reported in the world literature. The presenting symptom was spontaneous cerebrospinal fluid (CSF) rhinorrhoea which arose from a bony defect associated with herniation of the right temporal lobe into the sphenoid sinus. We discuss the management of such a case including imaging of the skull base and the endoscopic repair of the bony defect.

Cadaveric Model

Background For patients with obstructive sleep apnea (OSA), there is a lack of knowledge regarding the impact of continuous positive airway pressure (CPAP) on the nasal cavity. There is a significant need for evidence-based recommendations regarding the appropriate use of CPAP following endoscopic sinus and skull base surgery. Objective The goal of this study is to translate a previously developed cadaveric model for evaluating CPAP pressures in the sinonasal cavity by showing safety in vivo and quantifying the effect of positive pressurized air flow on the nasal cavity of healthy individuals where physiologic effects are at play. Methods A previously validated cadaveric model using intracranial sensor catheters has proved to be a reliable technique for measuring sinonasal pressures. These sensors were placed in the nasal cavity of 18 healthy individuals. Pressure within the nose was recorded at increasing levels of CPAP. Results Overall, nasal cavity pressure was on average 85% of delivered CPAP. The amount of pressure delivered to the nasal cavity increased as the CPAP increased. The percentage of CPAP delivered was 77% for 5 cmH2O and increased to 89% at 20 cmH2O. There was a significant difference in mean intranasal pressures between all the levels of CPAP except 5 cmH2O and 8 cmH2O ( P < .001). Conclusion On average, only 85% of the pressure delivered by CPAP is transmitted to the nasal cavity. Higher CPAP pressures delivered a greater percentage of pressurized air to the nasal cavity floor. Our results are comparable to the cadaver model, which demonstrated similar pressure delivery even in the absence of anatomic factors such as lung compliance, nasal secretions, and edema. This study demonstrates the safety of using sensors in the human nasal cavity. This technology can also be utilized to evaluate the resiliency of various repair techniques for endoscopic skull base surgery with CPAP administration.

Skull Base Defect

Today, endoscopic endonasal approach is considered the gold standard in skull base surgery of the chiasmosellar region. Advances in transnasal endoscopic skull base surgery allow conducting more extensive interventions via wider approaches which requires more complicated plastic closure of the skull base defect. In 2006, G. Haddad et al. suggested using a vascularized nasoseptal flap to reconstruct a skull base defect. This method is generally accepted at present due to its reliability and low frequency of postoperative complications. The purpose of this article is to analyze publications on possible complications and pathological conditions of the nasal cavity when using a vascularized nasoseptal flap for skull base surgery after removal of neoplasms of the chiasmo-sellar region. The study included articles found in the Pubmed database (2006–2020) which described frequency and character of complications caused by skull base defect reconstruction by a nasoseptal flap after transnasal removal of chiasmo-sellar neoplasms. According to the literature review, the following complications are reported: cerebrospinal fluid leak, flap necrosis and infectious complications, pathological changes in the nasal cavity: prolonged crusting, synechiae, epistaxis, septum perforation, sinusitis, subatrophic changes of mucosae, nasolacrimal duct obstruction, olfactory dysfunction. The authors conclude that the nasoseptal flap is, undoubtedly, an effective material for reconstruction of dural defects by endoscopic endonasal skull base surgery, because of its good viability due to the preserved blood supply and high tightness of the plasty. However, there is a risk of complications in the nasal cavity. For these reasons, development of effective methods for prevention of nasal complications after using a vascularized flap in endoscopic endonasal surgery is an important issue today.

✓ The orbitozygomatic craniotomy is one of the workhorse approaches of skull base surgery, providing wide, multidirectional access to the anterior and middle cranial fossae as well as the basilar apex. Complete removal of the orbitozygomatic bar increases the angles of exposure, decreases the working depth of the surgical field, and minimizes brain retraction. In many cases, however, only a portion of the exposure provided by the full orbitozygomatic approach is needed. Tailoring the extent of the bone resection to the specific lesion being treated can help lower approach-related morbidity while maintaining its advantages. The authors describe the technical details of the supraorbital and subtemporal modified orbitozygomatic approaches and discuss the surgical indications for their use. Modifications to the orbitozygomatic approach are an example of the ongoing adaptation of skull base procedures to general neurosurgical practice.

Abstract Objective Patients undergoing endoscopic endonasal surgery have historically been restricted from using straws postoperatively, due to the concern that this activity generates negative pressure. The objective of this study is to evaluate the pressure dynamics in the sinonasal cavity associated with the use of a straw. Methods Intracranial pressure catheters were placed in the nasal cavity of 20 healthy individuals. Pressure measurements were then recorded while participants drank liquids of different viscosities from a cup and from a straw. Measurements were recorded with and without subjects occluding their nose to simulate postoperative nasal obstruction. Results The average pressure in the nasal cavity while drinking water from a cup was −0.86 cmH2O, from a straw was −1.09 cmH2O, and while occluding the nose and using a straw was −0.81 cmH2O. The average pressure in the nasal cavity while drinking a milkshake from a cup was −0.98 cmH2O, from a straw was −1.88 cmH2O, and while occluding the nose and using a straw was −1.37 cmH2O. There was no statistically significant difference in pressure measurements when comparing either task or consistency (p > 0.05). Conclusion Straw use is not associated with the generation of significant negative pressure in the nasal cavity. The pressure generated when drinking from a straw is not significantly different from that of drinking from a cup. This data suggest that straw use may be safe for patients following endoscopic skull base surgery, but further investigation is warranted.

Introduction. Ameloblastoma is a rare, locally invasive benign jaw tumour, originating from odontogenic epithelium, and their presence in the sinonasal tract is usually due to their spread from the gnathic region of the maxilla. Primary sinonasal ameloblastoma is extremely rare, with only a handful of reported cases so far. The objective of this article was to describe a patient with a primary ameloblastoma of the right maxillary sinus and nasal cavity. Case outline. We report a case of a 67-year-old male patient with a year-long history of progressive unilateral nasal obstruction. Clinical and computed tomography examination revealed a mass in the right maxillary sinus and right nasal cavity. After an in-office biopsy under local anesthesia, which suggested the diagnosis of ameloblastoma, the patient underwent complete removal of the mass by a medial partial maxillectomy. Histopathologic analysis confirmed the diagnosis of ameloblastoma. Conclusion. Primary sinonasal ameloblastoma is clinically and radiographically similar to the more common pathology of this particular area and should be included in the differential diagnosis of the unilateral nasal obstruction. The treatment of choice is complete surgical resection. Due to the rarity of the disease, and a small number of cases described so far in the literature, there is still no consensus regarding the optimal surgical technique.

ABSTRACT Introduction An inverted papilloma is a benign tumor that is found in the nasal cavity or paranasal sinuses. Inverted papilloma accounts for approximately 0.5 to 2.0% of all nasal tumors. While it is considered benign, an inverted papilloma can destroy the surrounding bone. In a small number of cases (5-15%), an inverted papilloma may be found with a squamous cell carcinoma; one such case is reported. Case report A 70-year-old male presented with complaints of right-sided nasal blockage, which progressively increased over time and nasal discharge since one and half years with occasional history of epistaxis. On anterior rhinoscopic examination, there was a fleshy polypoidal mass filling the right nasal cavity. Contrast-enhanced computed tomography revealed a soft tissue density mass filling maxillary sinus and posterior choana with mild enhancement. Endoscopic medial maxillectomy was performed with complete removal of mass. Histopathological diagnosis was given as inverted sinonasal papilloma with malignant transformation. The patient was referred to a cancer reference center for treatment and received combined radiotherapy and chemotherapy. Patient was disease free at 6-month follow-up. Conclusion An inverted papilloma is a benign tumor with a propensity for malignant change. For these reasons, inverted papilloma should be treated like malignant tumor of the nasal cavity and paranasal sinuses. How to cite this article Prinja S, Davessar JL, Luthra H, Kaur M.
