Endoscopic treatment of juvenile nasopharyngeal angiofibromas: our experience and review of the literature.

The endoscopic resection of juvenile nasopharyngeal angiofibroma (JNA) emerges as an alternative approach to open procedures due to reduced morbidity and comparable recurrence rates. The purpose of this study was to present our experience with the endoscopic management of JNA using retrospective chart review of ten male patients (mean age 15.7 years) with JNA who were treated endoscopically at our institution between the years 2003 and 2010. According to the Radkowski's system, one patient was at stage Ia, two at stage Ib, one at stage IIa, two at stage IIb, two at stage IIc (infratemporal fossa invasion) and two at stage IIIa (clivus erosion). Six patients underwent preoperative embolization. The endoscopic treatment involved total ethmoidectomy, middle meatal antrostomy, sphenoidotomy, clipping of the sphenopalatine artery and its branches and drilling of the pterygoid basis. All patients underwent magnetic resonance imaging 3 months postoperatively and then if indicated clinically. Mean follow-up was 23.7 months (range 3-70). All but one patient were free of macroscopic disease. A patient with stage IIb JNA developed a recurrence after 9 months. The residual tumor was resected endoscopically and the sphenopalatine foramen widened by drilling. The patient is free of disease 25 months postoperatively. The intra-operative blood loss was not excessive (200-800 ml, mean: 444 ml) and no patient required a blood transfusion. Patients were discharged after 4-8 days (mean 5 days). One patient developed postoperative infraorbital nerve hypoesthesia. Results showed that endoscopic treatment of stage I and IIa/b JNA is a valid alternative to external approaches. For select tumors with limited infratemporal fossa invasion and skull base erosion, the endoscopic approach may also be indicated. It is a safe and effective treatment modality due to the lack of external scars, minimal bone resection and blood loss and low recurrence rate.

Extratemporal facial nerve branching patterns: systematic review of 1497 cases.

OBJECTIVE: The aim of this systematic review was to analyse the complex anatomy of the extratemporal portion of the facial nerve with an accurate description of the branching patterns based on the Davis classification. METHOD: Medline, ScienceDirect and the Cochrane Library databases as well as other sources were searched by two independent reviewers. RESULTS: Analysis of 21 studies with a total of 1497 cases showed that type III is the most common branching pattern accounting for 26.8 per cent of cases. The type I pattern, previously considered as the normal anatomy in most textbooks, was the fourth most common branching pattern at 16.3 per cent. The majority of specimens (96.4 per cent) were found to have a bifurcated main trunk, and only 3.2 per cent were found with a trifurcated main trunk. CONCLUSION: Surgeons should be aware of anatomical variations in the course of the facial nerve. An early identification of the branching pattern during surgery reduces the risk for iatrogenic facial nerve injury.

The value of bilateral simultaneous nasal spirometry in the assessment of patients undergoing septoplasty.

PROBLEM: There is no consensus regarding the best approach to select patients for septoplasty. Patient dissatisfaction after septoplasty implies that clinical examination alone is inadequate to detect a clinically relevant nasal septal deviation (NSD). Objective testing provides an in-depth analysis of nasal obstruction and its underlying anatomic causes but it is effort consuming, requires training and it is not widely available. AIM: We studied the role of bilateral simultaneous nasal spirometry (BSNS) in the preoperative selection of patients for septoplasty. PATIENTS, SUBJECTS AND METHODS: Thirty patients with nasal obstruction and NSD were assessed by subjective measures and BSNS before and after septoplasty. The decongested nasal partitioning ratio (NPR) was used as a measure of the degree of NSD. Thirty healthy controls were recruited for providing a normal range of NPR values. RESULTS: All patients were subjectively improved after septoplasty but only those with NPR out of the normal limits had a significant reduction of NPR. Patients with unilateral symptoms and NPR beyond normal limits were also able to identify the more obstructed side preoperatively. For this group of patients, physicians were able to identify the convex side of NSD preoperatively. No correlation between subjective measures of nasal obstruction or airflow asymmetry and NPR was observed. CONCLUSION: BSNS is a rapid, easily interpretable, noninvasive technique, which identifies patients with large NSDs who, irrespective of concomitant mucosal factors of nasal obstruction, warrant septoplasty. BSNS is not applicable in cases with a septal perforation or an S type septal deviation, it cannot detect an insufficient nasal valve and it does not substitute rhinomanometry or acoustic rhinometry.

Twenty-year experience with salvage total laryngectomy: lessons learned.

OBJECTIVE: The purpose of this study was to evaluate the outcome of salvage total laryngectomy and identify areas for further improvement. METHOD: A retrospective analysis of all patients who underwent salvage total laryngectomy between January 1999 and December 2018 was performed. RESULTS: Thirty-one patients were identified. The most common primary tumour site was the glottis (83.8 per cent). Early stage (T1-T2) disease was identified in 83.9 per cent of cases. Overall survival at 2 and 5 years post-salvage total laryngectomy was 71 per cent and 45 per cent, respectively. Disease-free survival at 2 and 5 years post-salvage total laryngectomy was 65 per cent and 42 per cent, respectively. The rate of post-salvage total laryngectomy pharyngocutaneous fistula was 29 per cent. CONCLUSION: More than half of patients will not survive beyond five years after salvage total laryngectomy. Regional recurrence was the most common form of failure and death. From this study, elective lateral and central neck dissection is advocated in patients with early laryngeal cancer who present with an advanced recurrence.

Bilateral multiple sialolithiasis of the parotid gland in a patient with Sjögren's syndrome.

The presence of multiple calculi in the major salivary glands is an uncommon finding. Sjögren's syndrome is a chronic autoimmune disease characterized by lymphocyte-mediated destruction of the exocrine glands. The case is presented of a 49-year-old female with Sjogren's syndrome found to have bilateral multiple sialolithiasis in the parenchyma of the parotid glands. The patient presented with a right sided painful inflamed swelling of the parotid region. Even though she had been diagnosed with primary Sjögren's syndrome 3 years prior to admission, she did not report any previous episode of sialadenitis. Full blood count showed leukocytosis (white blood cells = 14,900/10(6) L) with neutrophilia (75%). Radiological assessment included ultrasound and computed tomography scan of the parotids which demonstrated intra-parenchymal multiple calculi of both parotid glands and obstruction of the right Stensen's duct. The patient was treated with intravenous antibiotics and anti-inflammatory drugs. On the second day of hospitalisation, she reported spontaneous extrusion of a calculus during massage of the gland, with immediate relief of symptoms. In patients with Sjögren's syndrome and radiological findings of calculi in the major salivary glands, close observation is mandatory for better control of recurrent sialadenitis and early recognition of mucosa-associated lymphoid tissue lymphomas.

Management of spontaneous cerebrospinal fluid leaks of the sphenoid sinus: our experience.

BACKGROUND: Closure of spontaneous sphenoid sinus cerebrospinal fluid leaks can be challenging because of the relative inaccessibility of the lateral recess and the presence of intracranial hypertension. We present our experience of such cases and highlight factors associated with a successful outcome. METHODS: Eleven patients with spontaneous, laboratory confirmed, sphenoid sinus cerebrospinal fluid leaks were included. All patients underwent endoscopic closure by either a three-layer technique or fat obliteration. RESULTS: In all but one patient, the leak was successfully sealed (success rate, 90.9 per cent; mean follow up, 37.1 months). Elevated intracranial pressure was measured in eight patients, two of whom did not exhibit relevant clinical or radiological characteristics. Five patients received diuretics and dietary advice for weight reduction. In one patient with recurrence two weeks after repair, successful revision was performed by additional placement of a ventriculoperitoneal shunt (follow up, 67 months). CONCLUSION: Long-lasting cerebrospinal fluid fistula sealing in the sphenoid sinus requires stable reconstruction of the defect in three layers or fat obliteration if the anatomy is unfavourable. All patients should be intra- and post-operatively screened for elevated intracranial pressure to identify those who need additional intracranial pressure reduction measures.

Lateralized olfactory difference in patients with a nasal septal deviation before and after septoplasty*.

BACKGROUND: Patients with a smell disorder and less often, healthy people, exhibit an olfactory difference between the two sides of the nose. Higher olfactory thresholds are correlated with the obstructed side of a nasal septal deviation (NSD). With this prospective study we sought to investigate if a NSD compromises the olfactory identification. MATERIALS AND METHODS: Thirty patients with nasal obstruction due to a NSD were recruited. The patients were listed for primary septoplasty with or without radiofrequency reduction of the inferior turbinates. Pre- and postoperatively, patients were assessed by visual analogue scales for symptoms and by the bilateral nasal spirometry (nasal partitioning ratio-NPR) for the side/degree of obstruction. Olfactory identification was tested separately for each nasal cavity by means of the 12 item Sniffin Sticks test (12-SS test) and a 3-point difference between the nasal sides was considered significant. RESULTS: The mean age of patients (25 males/5 females) was 33 years (range 17-52). No complications or anosmia were reported postoperatively. Subjective hyposmia, nasal obstruction and the NPR were reduced (p<0.001). Significant lateralized differences were present in 20% and 13% of patients before and after septoplasty respectively; the change was not significant (p=0.754). Patients with a significant lateralized olfactory difference had a greater NPR pre- (p=0.031) but not postoperatively (p=0.783). The sides of obstruction and worst olfactory performance did not differ in these patients before surgery. CONCLUSIONS: Olfactory identification may be compromised on the convex side of a large NSD. Post-operatively, patients exhibit a lateralised smell identification difference as often as healthy people. The effect of a clinically significant NSD on the different aspects of olfactory performance warrants further study.

Management of paediatric sinonasal rhabdomyosarcoma.

BACKGROUND AND AIM: Rhabdomyosarcoma is the commonest malignant tumour of the nose and paranasal sinuses in the paediatric population. Due to its rarity and largely unknown biological behaviour, the treatment of this tumour is complex and controversial. We present the results of multimodality treatment of paediatric sinonasal rhabdomyosarcoma, and we explore the role of surgery in the management of this malignancy. METHODS: We retrospectively reviewed the records of 14 patients (median age 7.5 years) with sinonasal rhabdomyosarcoma. Six patients underwent major surgery with post-operative chemoradiation. Eight patients received multi-agent chemotherapy and radiotherapy. The mean follow-up time was 58 months (range seven to 276 months). RESULTS: The five-year overall survival rates for all patients and for the surgery group were 53.9 and 83.3 per cent, respectively. All patients with alveolar rhabdomyosarcoma had a poor prognosis, with a median survival time of 17 months. Intracranial extension and an age greater than 10 years were also associated with an unfavourable outcome. Non- or partial responders to initial chemoradiation died within a year of diagnosis. CONCLUSIONS: Management of paediatric rhabdomyosarcoma requires a combination of chemotherapy, radiotherapy and surgery. Primary chemoradiotherapy is the established treatment approach for advanced tumours. Early stage tumours with favourable histology can be treated successfully with radical surgery, provided that function and cosmetic appearance are preserved.

Intraparotid facial nerve schwannoma: management options.

Intraparotid facial nerve schwannoma (FNS) is a very rare, benign tumour mimicking pleomorphic adenoma. Resection of this slow growing tumour may result in unnecessary facial nerve paralysis. The aim of this study is to present results of facial nerve schwannoma treatment at our institution and proposes a management plan. This is a retrospective case series of four patients, three male and one female with a mean age of 47.7 years who presented with a long-standing, asymptomatic parotid swelling. Two patients had facial weakness and underwent superficial parotidectomy, resection of tumour and facial nerve repair with a free graft from the greater auricular nerve. Two patients underwent biopsy without tumour resection. All tumours were confirmed histologically as facial nerve schwannomas. The mean follow up period was 3.5 years. Patients with resection of facial nerve schwannoma had a postoperative House Brackmann grade III and IV. Patients with biopsy had normal postoperative facial nerve function and the tumour did not grow significantly. No adverse effects or recurrence were reported. There is no preoperative diagnostic modality that can identify facial nerve schwannoma with certainty. Difficulty in locating the facial nerve intraoperatively raises suspicion of a neurogenous tumour of the facial nerve and this may prevent unnecessary damage to the nerve. Not every facial nerve schwannoma should be resected. This decision is based on (a) the extent of tumour (b) preoperative facial nerve function (c) best results achieved with nerve repair and (d) patient's preferences. Large tumours with extension into the mastoid cavity or encroachment of sensitive structures and preoperative facial weakness are indications for surgical intervention. In most other cases, biopsy and observation suffices.

Unsuspected breast carcinoma presenting as orbital complication of rhinosinusitis.

We report a rare clinical presentation of breast carcinoma metastasis to the ethmoid sinuses, orbit and cavernous sinus in a 70-year-old lady with unsuspected breast carcinoma who presented with clinical features of acute ethmoiditis, orbital cellulitis and cavernous sinus thrombosis. The patient underwent endoscopic ethmoidectomy and histology of the necrotic tissue from the ethmoidal cells was positive for endovascular neoplastic emboli. Subsequent examination revealed a large mass in the left breast, tethered to the skin, which was histologically confirmed to be a carcinoma. The patient died 2 months post-diagnosis. To our knowledge, this is the third case manifesting with combined features of ethmoiditis, orbital cellulitis and cavernous sinus syndrome from an unsuspected breast carcinoma. This case highlights the importance of imaging and thorough physical examination when a dramatic clinical picture presents in the paranasal sinuses of an otherwise healthy individual. Such manifestation of breast carcinoma is difficult to diagnose, and therefore, a high index of suspicion should be maintained. Skull base metastases from breast carcinoma behave aggressively and if diagnosed early, treatment may prolong survival and improve quality of life.

Primary aneurysmal bone cyst of the maxillary sinus in a child: case report and review of the literature.

Our case report describes a primary aneurysmal bone cyst (ABC) of the maxillary sinus in a 12-year-old girl. The young patient presented with progressive diplopia, strabismus, and rapidly growing painless swelling of the left cheek. Imaging studies showed a heterogeneous contrast enhancing mass expanding the left maxillary sinus. The lesion was completely resected endoscopically and histological examination reported it as an ABC. The patient recovered well and is free of recurrence 9 months following surgery. ABC is a benign lesion usually associated with other bone pathology (fibrous dysplasia). It may behave aggressively and invade the orbit; so resection is necessary. Minimally invasive techniques such as endoscopic sinus surgery can be performed successfully in select cases. Long follow up is important because recurrence may occur, in which case further resection is warranted.

Endoscopic versus open surgical interventions for inverted nasal papilloma: a systematic review.

Inverted nasal papilloma is a unique neoplasm characterised by a tendency to recur following excision, an association with malignancy and an ability to destroy bone. The coexistence with nasal polyps (not always sent for histology), the lack of a universally accepted staging system and the fact that most data on Inverted papilloma come from tertiary centres (selected cases probably the most aggressive) account for the difficulty in determining its true incidence. Treatment is surgical. The gold standard approach was an open radical procedure. The introduction of endoscopic surgery for primary or recurrent lesions has shown potential advantages. Lack of complications of open surgery together with improved access to specific nasal areas suggests that the endoscopic techniques in experienced hands and for selected lesions may be a good alternative. The aim of this review was to assess the effectiveness of the endoscopic versus open techniques for management of inverted papilloma. There is not enough evidence in the literature to support one or the other treatment option for management of inverted papilloma. There is a trend though towards endoscopic approach. Ideal management should aim at complete removal of all diseased mucosa with creation of wide cavities and long term follow-up to detect subsequent recurrence or malignant transformation.
