Huge nasopharyngeal angiofibroma with intracranial extension: change in the dura mater and choice of surgical management

Multidiscipline management of giant reccurent nasopharyngeal angiofibroma which extends to paranasal sinuses, orbita, and intracranial in adult

Nasopharyngeal angiofibroma (NA) is a benign, slowly growing tumour that affects males in their early puberty, and rarely men over 25 years of age. There was an interesting case of a giant recurrent NA in a 62-year-old male, which is challenging to manage due to wide tumour expansion to paranasal sinuses, orbital and intracranial. In cases of large angiofibromas disease, preoperative embolization should be performed to prevent profuse bleeding. Wide expansion of NA can cause post extirpation large defects of the tumour so that optimal defect closure techniques are needed to restore the aesthetics and function of the disturbed organs. This case's diagnosis and management of this disease was carried out by multidisciplinary discussion, and surgical extirpation of the joint tumour was performed in Dr. Soetomo General Academic Teaching Hospital. The tumour was removed by medial maxillectomy with an extended Killian right lateral rhinotomy approach followed by tumour defects reconstruction. The follow up showed that there were still tumour residue and suspicious intracranial abscess, but the patient had no complaint during follow-up for ten months after surgery.

•

Nasopharyngeal angiofibroma (NA) is a benign but locally aggressive tumor and rarely appears in adults. Although it is rare, NA should not be disregarded in elderly patients. Histopathological tests showed different results before surgery.

•

The surgical technique chosen is embolization, MMRL and facial reconstruction through joint surgery ORL-HNS, Ophthalmologist, Neurosurgeon, and Plastic Reconstructive & Aesthetic Surgeon because of the large size of the tumor and has spread aggressively to the intracranial and many blood vessels involved.

•

The result concluded a benign mesenchymal spindle tumour with a differential diagnosis of solitary fibrous tumour, neurofibroma cellular schwannoma, and angiofibroma. The patient was advised to undergo an immunohistochemical examination to establish a tumour diagnosis, but this was not done due to constraints on equipment and family considerations related to the Covid-19 pandemic.

•

Evaluation of the results of surgery and recurrence events has been carried out for 10 months postoperatively and there are no complaints and the patient can carry out activities as usual.

Management of Pterygoid Venous Plexus Hemorrhage during Resection of a Large Juvenile Nasopharyngeal Angiofibroma: A Review of 27 Cases

We retrospectively reviewed the cases of 27 patients who experienced intraoperative bleeding during resection of a large (Fisch type III or IV) juvenile nasopharyngeal angiofibroma (JNA). Of this group, 16 patients had a type III JNA and 11 had a type IV tumor. The degree of hemorrhaging during excision of these JNAs varied greatly among individual patients. The amount of blood lost ranged from 200 to 5,000 ml (mean: 1,800) in the type III cases and from 700 to 8,000 ml (mean: 2,850) in the type IV cases. In 5 of these cases, both intraoperative observations and imaging data suggested that an important factor in the blood loss was damage to the pterygoid venous plexus (PVP). The PVP communicates with the cavernous sinus, ophthalmic vein, maxillary vein, and facial vein; no valve exists between these veins. In patients with a large JNA, the PVP is usually compressed by or adherent to the tumor. When a PVP is seriously damaged during removal of a JNA, hemorrhaging can be very profuse. Therefore, a suitable surgical approach and appropriate hemostatic procedures should be used to prevent or manage PVP hemorrhage as effectively as possible. We also describe in greater detail 5 typical cases of JNA excision that did (n = 3) and did not (n = 2) involve PVP damage.

Management of pterygoid venous plexus hemorrhage during resection of a large juvenile nasopharyngeal angiofibroma: a review of 27 cases

Nasopharyngeal angiofibroma: a concise classification system and appropriate treatment options

OBJECTIVES

To describe a clear and simplified classification system for juvenile nasopharyngeal angiofibroma (JNA), and to describe suitable management options.

STUDY DESIGN

Retrospective medical record review.

METHODS

The clinical and imaging materials of 51 cases of JNA diagnosed at our hospital between 1981 and 2011 were collected and studied. Based on our experiences, we prefer to divide JNAs into three types. Type I includes JNAs fundamentally localized to the nasal cavity, paranasal sinus, nasopharynx, or pterygopalatine fossa. Type II is a JNA extending into the infratemporal fossa, cheek region, or orbital cavity, with anterior and/or minimal middle cranial fossa extension but intact dura mater. Type III is a calabash-like massive tumor lobe in the middle cranial fossa. The management and prognosis for the three types of JNA were compared and evaluated.

RESULTS

Among cases of type I JNA (n=16), the entire mass was removed by the initial operation in 15 cases and by a repeat operation in 1 case. Among cases of type II JNA (n=29), the entire mass was removed by the first operation in 24 cases and by repeat operation in 5 cases. In cases of type III JNA (n=6), the huge calabash-like lobe in the middle cranial fossa could not be completely excised; 4 cases underwent radiotherapy and 2 cases were lost to follow-up.

CONCLUSIONS

1) The transnasal cavity approach with endoscopic guidance is suitable for type I JNA resection. 2) The transantral-infratemporal fossa-nasal cavity combined approach is reliable for resection of a type II JNA, which extends into the deep anterior cranial fossa and/or minimally into the middle cranial fossa, with intact dura mater. 3) The complete removal of a type III JNA is difficult, even through a combined extracranial and intracranial approach. Radiotherapy is useful for treating the residual intracranial tumor. The successful or failed experiences of 6 typical cases prove that this revised classification system is reasonable and reliable.

Comparison between endoscopic and open surgery in 37 patients with nasopharyngeal angiofibroma

Juvenile nasopharyngeal angiofibroma is a rare benign vascular tumor of the nasopharynx. Although the treatment of choice is surgery, there is no consensus on what is the best approach.

AIM

To compare surgical time and intraoperative transfusion requirements in patients undergoing endoscopic surgery versus open / combined and relate the need for transfusion during surgery with the time between embolization and surgery.

MATERIAL AND METHODS

Study descriptive, analytical, retrospective study with a quantitative approach developed in the Otorhinolaryngology department of a teaching hospital. Analyzed 37 patients with angiofibroma undergoing surgical treatment. Data obtained from medical records. Analyzed with tests of the Fisher-Freeman-Halton and Games-Howell. Was considered significant if p <0.05.

STUDY DESIGN

Historical cohort study with cross-sectional.

RESULTS

The endoscopic approach had a shorter operative time (p <0.0001). There is less need for transfusion during surgery when the embolization was performed on the fourth day.

CONCLUSION

This suggests that the period ahead would be ideal to perform the process of embolization and endoscopic surgery by demanding less time would be associated with a lower morbidity. This study, however, failed to show which group of patients according to tumor stage would benefit from specific technical.

Treatment and prognosis of nasopharyngeal angiofibroma involving the eye and optic nerve

OBJECTIVE

To discuss the minimally invasive treatment and prognosis of juvenile nasopharyngeal angiofibroma involving the eye and optic nerve.

METHODS

Retrospective analysis of clinical data for 18 large juvenile nasopharyngeal angiofibromas, with reports of three typical cases.

RESULTS

The tumour invaded the orbit, eye, optic nerve and optic chiasm in 18, 9, 8 and 5 patients, respectively. Twelve patients were cured after surgery, with the affected eye and vision essentially returning to normal. In six patients, tumour residue was found in the middle cranial fossa; two of these six did not return for follow up. Four patients underwent radiotherapy; all four regained placement of the eye in a normal or near-normal position. One of these four patients regained normal visual acuity, two experienced no improvement in visual acuity, and one became blind.

CONCLUSION

In patients with this tumour, surgery may return the eye to the normal position and may restore visual acuity if the optic fundus, macula, retina and optic nerve are only mildly affected. Modern radiotherapy can treat the intracranial residue effectively. A combined approach via the antrum, infratemporal fossa and nasal cavity, using a Caldwell-Luc incision, provides minimally invasive surgical access.

Nasopharyngeal Angiofibroma-changing Trends in the Management

Juvenile nasopharyngeal angiofibroma is a rare high-risk tumor of adolescent males. To present the experience of managing extensive angiofibroma at a single institution. A retrospective analysis of patients with nasopharyngeal angiofibroma between 1980 and 2009. 150 patients have been included in the analysis. The patients have been divided into two groups depending on diagnostic and therapeutic protocols into two groups. A 1980-1990 and B from 1990 to 2009. The disease pattern, surgical approaches and outcome in the two groups have been analyzed. Surgery has been the main modality for management of this tumor. Preoperative embolization and open surgical approaches results in less blood loss and favourable outcome.

Surgical management of large juvenile nasopharyngeal angiofibroma invading the infratemporal fossa with intracranial extradural parasellar involvement in an 8-year-old boy

We present a rare case of a large juvenile nasopharyngeal angiofibroma (JNA) in an 8-year-old boy. Preoperative imaging revealed that the tumor had widely extended to the sphenoid sinus, infratemporal fossa, and cavernous sinus. Following embolization of the feeding vessels, the tumor was successfully removed by a combination of an orbitozygomatic approach and Le Fort I osteotomy under frontolateral craniotomy. An endoscope assisted in the surgery. At 15 months follow-up, the patient was free of the disease with no facial palsy, scars, or malocclusion. JNA is a benign tumor that typically affects adolescent males and is rarely observed during prepuberty. Complete removal of JNA by surgery, the initial therapy, is generally required. However, as in the present case, a large JNA with wide extension requires extended surgery, and such a surgery is more invasive for prepubertal patients. Using an appropriate combination of surgical approaches, a large JNA developed during prepuberty can be safely removed with reduced morbidity.

Advanced craniofacial juvenile nasopharyngeal angiofibroma. Description of surgical series, case report, and review of literature

BACKGROUND

Juvenile nasopharyngeal angiofibroma (JNA) is a rare benign tumor occurring almost exclusively in adolescent and young adult males. The tumor is characterized by slow progression, aggressive growth, high vascularization, and increased rate of persistence and recurrence. The aim of this study was to describe a case of giant JNA from our practice and discuss the controversies of surgical treatment of advanced JNA.

MATERIAL AND METHODS

A series of 29 consecutive male patients with JNA Fisch grade III and IV was surgically treated in Burdenko Neurosurgical Institute from 2000 until 2008. In the vast majority of cases, endovascular embolization and surgical removal via orbitozygomatic approach were applied.

RESULTS

Gross total resection was achieved in 24 cases (83%). Complications were encountered in eight cases. No mortality was observed. In three patients, the diseases recurred. An illustrative case is described.

CONCLUSION

Surgical treatment is the basic tactics in management of extensive JNA including endovascular embolization and resection of the tumor. We recommend using orbitozygomatic approach or its modifications in JNA. Radiation therapy may be recommended for patients with small residual tumor.

Lacrimal hyposecretion: a surgical complication of juvenile nasopharyngeal angiofibroma

PURPOSE

The aim of this study was to evaluate lacrimal hyposecretion in the surgical management of juvenile nasopharyngeal angiofibroma (JNA) and discuss how to prevent and treat this expected surgical complication.

MATERIALS AND METHODS

Six cases of JNA were extirpated surgically in the last 3 years in our department. The clinical signs, results of the total tear secretion test (Schirmer I test), imaging studies, surgical findings, and pathologic changes in these cases are reviewed retrospectively.

RESULTS

Three of the 6 cases developed an irritated dry eye on the affected side postoperatively as a result of lacrimal hyposecretion, caused by damage to or partial removal of the pterygopalatine ganglion and vidian nerve. On follow-up for 1 to at least 2 years, the clinical signs disappeared in 2 cases, whereas there was no improvement in 1 case.

CONCLUSIONS

If a JNA originates near the pterygopalatine foramen adjacent to the pterygopalatine ganglion and vidian nerve, these may be damaged or partially removed intraoperatively. The consequent lacrimal hyposecretion can be a temporary or permanent complication.

SIGNIFICANCE

A few reports have described lacrimal hyposecretion as a surgical complication of JNA; there have been no articles reporting the prognosis of this complication or the related pathologic findings of the involved pterygopalatine ganglions. Prevention of this complication remains a clinical challenge.
