RESUMEN

OBJECTIVE: This study aimed to assess degree of audiovestibular handicap in patients with vestibular schwannoma. METHODS: Audiovestibular handicap was assessed using the Hearing Handicap Inventory, Tinnitus Handicap Inventory and Dizziness Handicap Inventory. Patients completed questionnaires at presentation and at least one year following treatment with microsurgery, stereotactic radiosurgery or observation. Changes in audiovestibular handicap and factors affecting audiovestibular handicap were assessed. RESULTS: All handicap scores increased at follow up, but not significantly. The Tinnitus Handicap Inventory and Dizziness Handicap Inventory scores predicted tinnitus and dizziness respectively. The Hearing Handicap Inventory was not predictive of hearing loss. Age predicted Tinnitus Handicap Inventory score and microsurgery was associated with a deterioration in Dizziness Handicap Inventory score. CONCLUSION: Audiovestibular handicap is common in patients with vestibular schwannoma, with 75 per cent having some degree of handicap in at least one inventory. The overall burden of handicap was, however, low. The increased audiovestibular handicap over time was not statistically significant, irrespective of treatment modality.

RESUMEN

Background Regardless of the operative approach, headache, cerebrospinal fluid (CSF) leaks, and pseudomeningoceles remain disproportionately common problems after surgery for vestibular schwannomas and have a significant negative impact on quality of life and potential to return to full employment. Recent work has raised the possibility that these problems may, in part, be related to acquired obstruction of cranial venous outflow. This article explores this idea further with respect to a group of patients with severe and intractable symptoms. Objective The main objective of this article is to describe our experience diagnosing, investigating, and treating cranial venous outflow obstruction following translabyrinthine resection of vestibular schwannomas. Methods Retrospective review of all patients ( n = 9) at our institution referred for sigmoid sinus stenting following translabyrinthine surgery. Results Headache resolved or improved after sigmoid stenting in all five patients in whom it was the primary symptom. CSF leak was the primary problem in two patients. In one, the leak was unchanged, but headache improved. In the other, the leak resolved, and headache improved. Two patients had symptomatic pseudomeningoceles and both resolved Conclusion Assuming a meticulous approach to wound closure, a CSF leak following surgery for vestibular schwannoma can be viewed as a pathological, but essentially homeostatic, response to raised intracranial pressure caused by acquired obstruction to cranial venous outflow. Postoperative headache (from high or low intracranial pressure) and CSF leaks, therefore, may all respond to measures aimed at eliminating the obstructing lesion.

RESUMEN

OBJECTIVE: To review the treatment of squamous carcinoma of the temporal bone at a regional skull base unit for the period 1982-2012. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: Sixty patients with primary squamous carcinoma of the temporal bone. INTERVENTIONS: Multidisciplinary team approach including surgical resection, reconstruction, and postoperative radiotherapy. MAIN OUTCOME MEASURES: Disease-specific survival, overall survival. RESULTS: The 5-year disease-specific survival for the whole cohort was 44% (CI, 37%-51%). Multivariable analysis revealed nodal status, poorly differentiated squamous cell histology, and carotid involvement to be poor prognostic indicators. CONCLUSION: Although the survival figures in this series are comparable with the best outcomes from other units, our experience would suggest improvements can still be achieved by reconsidering the selection of patients for neck dissection and temperomandibular joint excision in early stage disease. We also conclude that postoperative radiotherapy should be delivered to all patients, including surgical salvage cases who may have received previous irradiation. Finally, the minority of patients with poor prognostic features should be offered a more palliative therapeutic approach.

RESUMEN

OBJECTIVE: To assess the growth characteristics of small- to medium-sized vestibular schwannomas in patients undergoing watch, wait, and rescan management. STUDY DESIGN: Cohort study using prospectively collected size and tumor morphology data. SETTING: Tertiary referral center for cranial base surgery. SUBJECTS AND METHODS: Three hundred eighty-one patients with sporadic unilateral vestibular schwannomas and 2 or more magnetic resonance scans were included. Linear measurements were used to assess tumor size. The point of growth and pattern of growth progression were assessed. Factors influencing growth were investigated. RESULTS: Approximately 33% of tumors demonstrated significant growth. Mean size at presentation was 9.9 mm (standard deviation [SD]. 4.8). For growing tumors, mean size at final review was 13.7 mm (SD, 4.8). This was a statistically significant increase in size (p < 0.0001). Mean annual change in size for growing tumors was 2.3 mm (SD, 2.3). 52.4% of growing tumors showed radiologically demonstrable first growth within 18 months of presentation. Approximately 7.2% of tumors showed radiologically demonstrable first growth after 5 years of follow-up. There were no demographic or morphologic predictors of growth. CONCLUSION: Tumor growth is usually slow and is most likely to occur within the first 3 years of observation. Growth may occur after five years of follow-up. A protocol for the scanning of patients is suggested based on the findings of the study.

RESUMEN

Spontaneous temporal meningoencephaloceles are unusual. When they do occur, they present with a variety of signs and symptoms, which can make diagnosis and management challenging. We report the interesting case of a 49-year-old woman with bilateral congenital temporal meningoencephaloceles. She presented with a 12-month history of bilateral fluctuating hearing loss, and she more recently developed right-sided acute otitis media with meningitis. The presentation of bilateral extensive tegmental defects and meningoencephaloceles with a fluctuating hearing loss and meningitis associated with acute otitis media affecting one ear and then subsequently the other ear is extremely rare and difficult to diagnose. It requires a very careful clinical and radiologic assessment. Methods of surgical repair differ depending on the size of the defects.

RESUMEN

OBJECTIVES: To report our approach to the surgical management of vestibular schwannomas (VSs) and hearing rehabilitation in neurofibromatosis Type 2 (NF2). DESIGN: Retrospective cohort study. SETTING: Tertiary referral NF2 unit. PATIENTS: Between 1981 and 2011, seventy-five patients were managed in our NF2 unit, of which, 58 patients are under current review. MAIN OUTCOME MEASURES: Patients who underwent VS excision were evaluated for tumor size, surgical approach, and outcomes of hearing and facial nerve function. All current patients were evaluated for NF2 mutation, hearing, and auditory implantation outcomes. RESULTS: Forty-four patients underwent resection of 50 VS in our unit, of which, 14% had facial neuroma excision and reinnervation during the same operation. At 12 months after surgery, facial nerve outcomes were House-Brackmann (HB) 1 in 33%, HB2 in 21%, and HB3 in 30%. Total VS resection was achieved in 78% of patients using a translabyrinthine approach. Seventy-two percent of the current patients have American Association of Otolaryngology-Head and Neck Surgery class A to C hearing (maximum speech discrimination score over 50%) in the better hearing ear, and a further 14% are full-time users of cochlear implants or auditory brainstem implants. The remaining patients have been assessed for auditory implantation. CONCLUSION: By following a policy of treating VS in NF2 patients where tumor growth is observed, complete tumor resection can be achieved through a translabyrinthine approach while achieving comparable facial nerve outcomes to published series. We advocate proactive hearing rehabilitation in all patients with timely assessment for auditory implantation to maintain quality of life.

RESUMEN

The objective of this study is to determine whether magnetic resonance imaging (MRI) at 2 years following complete vestibular schwannoma (VS) excision using a translabyrinthine approach is sufficient to detect recurrent tumor. The study is set in a tertiary referral skull base unit. A service evaluation of a prospective database identified patients who underwent complete translabyrinthine VS excision with prospectively recorded MRI results at 2 and 5 years following surgery. The main outcome measures were evidence of tumor recurrence on MRI at 2 and 5 years after surgery. Of 314 patients in the study, all patients where MRI was reported to show no recurrence at 2 years (97%) also had no signs of recurrence on MRI at 5 years. All eight patients with MRI suspicious of recurrence (linear enhancement of internal auditory canal [IAC]) at 2 years had no progression on MRI at 5 to 15 years. One patient had evidence of definite recurrence (nodular enhancement of IAC) at 2 years, who went on to have radiosurgery at 8 years. Where patients have MRI with no linear enhancement of the IAC at 2 years, no further imaging is required. Where linear enhancement is seen, no change in enhancement at 5 years is reassuring and no further imaging is required.

RESUMEN

OBJECTIVES: To measure the health-related quality of life (QoL) of patients undergoing conservative management of a vestibular schwannoma and to identify audiovestibular factors that influence health-related QoL. STUDY DESIGN: Cross-sectional case-control study. INTERVENTION: Adult patients undergoing conservative management of a sporadic vestibular schwannoma were identified from a prospectively updated database. Each patient was asked to complete a series of questionnaires, including the Short Form 36 health-related QoL instrument, the Hearing Handicap Inventory, the Tinnitus Handicap Inventory, and the Dizziness Handicap Inventory. The QoL data obtained were compared with UK normal data. Multiple linear regression was performed to identify audiovestibular factors influencing QoL. PATIENTS: Of 241 patients still undergoing conservative management, 165 completed the questionnaires. The mean age was 66.6 years. Mean duration of follow-up was 5.7 years. RESULTS: Physical component summary scores were significantly lower than those of the normal population. Mental component summary scores were significantly above the normal population. Regression analysis showed that dizziness handicap score and age were strong predictors of physical component summary (both p < 0.0001). Dizziness handicap score and tinnitus handicap score were significant predictors of mental component summary (p = 0.0004 and p = 0.027 respectively). However, the model only explained a small amount of the data, suggesting that there may be other factors influencing QoL. CONCLUSION: Dizziness is the most significant audiovestibular predictor of QoL in patients with vestibular schwannomas. Tinnitus also has an impact on mental QoL. Hearing loss does not seem to influence QoL. Other factors such as illness perception may have an important role to play in determining QoL.

RESUMEN

Vestibular schwannomas are benign, slow-growing tumors that originate from Schwann cells lining the vestibular nerves, most commonly the superior vestibular nerve. They arise at the neurilemmal/neuroglial junction which is situated within the internal auditory canal. They have an incidence of 1 per 100,000 per year and a prevalence of around 700 per million. A case of a patient undergoing a period of observation for a vestibular schwannoma whose hearing improved despite growth of the tumor is described. This raises interesting questions regarding the pathophysiology of hearing loss in patients with vestibular schwannomas. Possible hypotheses are discussed.

RESUMEN

OBJECTIVES: To determine the prevalence of Bruns' nystagmus in patients undergoing surgical treatment for unilateral sporadic vestibular schwannomas (VSs), identify the clinical characteristics of patients with Bruns' nystagmus and compare these characteristics with those of VS patients with no nystagmus and other types of nystagmus, and determine the long-term impact of having preoperative Bruns' nystagmus. STUDY DESIGN: A retrospective review using a prospectively updated database of patients who had undergone surgical removal of a VS. Patients were divided into 3 groups: Bruns' nystagmus, other types of nystagmus, or no nystagmus. Statistical comparison of each group was undertaken. PATIENTS: Nine hundred eighty-four patients were included consisting of 492 men and 492 women with a mean age of 59 years (range, 11-86 yr). RESULTS: Bruns' nystagmus was present in 11% of patients. Bruns' nystagmus was associated with larger tumor size (p < 0.001). Beyond 3.5-cm maximum diameter, 92% of patients had nystagmus, 67% of which had Bruns' nystagmus. Preoperative balance impairment was present in 95% of patients with Bruns' nystagmus compared with 59% with no nystagmus. The balance status of all groups improved considerably postoperatively, but the patients with Bruns' nystagmus had a relatively greater improvement in balance status. CONCLUSION: Bruns' nystagmus occurs in patients with large VSs. These patients tend to have greater balance impairment pre\operatively, but after surgery, long-term balance outcomes are similar to those of patients with no nystagmus or other forms of nystagmus.

RESUMEN

Schwannoma of the facial nerve is an extremely rare condition with an incidence far lower than that of vestibular schwannoma. We discuss the case of a woman who had been diagnosed as having vestibular schwannoma and referred to our hospital. Initially, we concurred with the diagnosis, but on reassessment of magnetic resonance imaging scans before surgery, we revised the diagnosis to facial nerve schwannoma. This allowed us to counsel the patient appropriately preoperatively regarding the expected outcome. We discuss the importance of this case and the lessons to be learned from it.

RESUMEN

UNLABELLED: Squamous cell carcinoma (SCC) of the temporal bone is a rare, aggressive and highly malignant tumour that requires specialised, multidisciplinary surgery for its treatment. Reconstruction of the defect is as crucial as the tumour ablation in terms of mortality and postoperative morbidity. METHODS: The experience of the East Anglian Skull Base Surgery Service from 1982 to 2004 in managing 42 consecutive patients (22 females; age range 37-80 years) undergoing extended and lateral temporal bone resection for SCC is presented. RESULTS: The overall 5-year survival was 31.0% (median follow up: 97 months) when both curative and palliative procedures were included. On multivariate analysis, the favourable prognostic factors were male sex, well-differentiated tumours and stage N(0) neck. The reconstructions in 38 patients were analysed. The majority (24/38) had free tissue transfer reconstructions and most of these were radial forearm free flaps. Later in the series, other free flap types such as anterolateral thigh flaps and lateral arm flaps were employed. Pedicled myocutaneous flaps and local flaps were also used. CONCLUSIONS: This paper analyses the outcomes of the various reconstructions and discusses the evolution of their care in our unit. The information obtained from the review of our data is extrapolated to offer guidance on the choice of reconstructive option in these patients.

RESUMEN

OBJECTIVES: This study sought to determine explicitly whether postsurgical facial nerve outcomes for patients with a cystic component to a vestibular schwannoma were significantly different from those with a solid tumor. DESIGN: Seventy patients who underwent translabyrinthine surgery for a cystic vestibular schwannoma between May 1981 and the present, and who had complete records in our database, were identified. These were compared with a group of patients with solid tumors matched to the study group on the following parameters: House-Brackmann grade at presentation, tumor size, surgical approach, age. SETTING: Regional tertiary referral center. PARTICIPANTS: Adult patients with vestibular schwannomas. MAIN OUTCOME MEASURES: House-Brackmann score 2 years following surgery. RESULTS: No significant difference was found between the two groups. CONCLUSIONS: The perceived difference in outcomes between cystic and solid vestibular schwannomas cannot be demonstrated when confounding factors such as tumor size are taken into account.

RESUMEN

OBJECTIVES: The aim of this study was to evaluate the change of hearing and tinnitus in a group of conservatively managed unilateral vestibular schwannomas (VS). DESIGN: Retrospective case series review. SETTING: Tertiary referral otoneurological and skull base surgery department. PARTICIPANTS: Seventy patients affected by unilateral VS with at least two audiograms available were retrospectively evaluated. MAIN OUTCOME MEASURES: Changes in pure tone average (PTA), speech discrimination score (SDS), and tinnitus were analyzed. RESULTS: At diagnosis 16 patients (22.9%) had a PTA of 0 to 30 dB and 38 (54.4%) a PTA of 0 to 50 dB. At the end of the follow-up period, 9 patients (12.9%) had a PTA of 0 to 30 dB and 27 (38.7%) had a PTA of 0 to 50 dB, representing a hearing preservation rate of 56% and 70%, respectively. Of patients with both tonal and speech audiometry, 71.4% with class A hearing (PTA < 30 dB/SDS > 70%) maintained their initial hearing and 60% with class A or B hearing (PTA < 50 dB/SDS > 50%) maintained this useful hearing. Forty-two patients (60%) did not show a significant growth in their tumor over the period of observation. In this group of patients the mean PTA after a mean follow-up time of 40 months decreased from 44 dB HL to 50.8 dB HL, with a yearly rate of 2.47 dB HL. The chance of maintaining a PTA of 0 to 30 dB in this group of patients was 57.1% and a PTA of 0 to 50 dB was 81.4%. CONCLUSIONS: In this group of patients affected by VS and managed conservatively with a mean follow-up of 33.3 months, the risk of losing eligibility for hearing preservation surgery was lower than 30%.

RESUMEN

OBJECTIVES: To review the symptoms, signs, and clinical findings in a large series of patients diagnosed with unilateral sporadic vestibular schwannoma (VS) to describe the clinical characteristics of tinnitus in this population. Further, to ascertain which of the proposed mechanisms of tinnitus generation in VS was supported. DESIGN: Retrospective case note and database review. SETTING: Tertiary university teaching hospital departments of audiology and neuro-otology. PARTICIPANTS: Nine hundred forty-one patients with unilateral sporadic VS, diagnosed during the period 1986 to 2002. Twenty-three additional patients were excluded due to missing clinical data. MAIN OUTCOME MEASURES: The presence or absence of tinnitus, and its rated subjective severity were analyzed in conjunction with data regarding patient demographics, symptoms, signs, and diagnostic audiovestibular test findings. RESULTS: No statistical association at the 5% level was found between tinnitus presence/absence and patient age, gender, 2- to 4-kHz audiometric thresholds, ipsilateral auditory brainstem response abnormality, length of history, tumor side, nor caloric test abnormality. Statistically significant associations were found between tinnitus presence/absence and tumor size (p = 0.012) and type of hearing loss (progressive, sudden, fluctuant, nil) with a tendency for patients without hearing loss to be less likely to experience tinnitus. Statistically significant associations were identified between classification of tinnitus severity and age at diagnosis (p < 0.001) (greater age being associated with greater tinnitus severity), abnormal findings on caloric testing (p = 0.01) (abnormal calorics being associated with greater tinnitus severity), and tinnitus as a principal presenting symptom (p < 0.001) (this being associated with greater tinnitus severity). CONCLUSIONS: The analysis does not identify any single one of the proposed mechanisms for tinnitus as being the obvious culprit. In fact, even in a homogeneous group of patients such as this, there is evidence of multiple mechanisms that are not mutually exclusive. The association between increased tinnitus severity in older patients, patients with canal pareses on caloric testing, and with tinnitus as a principal presenting symptom should be borne in mind by the clinician.

RESUMEN

Malignant peripheral nerve sheath tumors are uncommon lesions that occasionally affect the head and neck. We describe 2 new cases of head and neck pathology. One tumor involved the parotid gland and resulted in erosion of the temporal bone, and the other affected the lower lip. A rapid diagnosis has significant implications for management because of the tumor's potential for aggressive behavior and its high rate of recurrence. To the best of our knowledge, lip involvement is rare and temporal bone involvement has not been previously described.

RESUMEN

Lateral skull base defects following tumor ablation are ideally reconstructed with microvascular free tissue transfer. Although the rectus abdominis free flap is the workhorse in skull base reconstruction, it has a number of drawbacks. Anecdotal reports have indicated that fasciocutaneous free flaps may be useful alternatives in selected cases. Patients undergoing lateral arm (4 cases) or anterolateral thigh (8 cases) fasciocutaneous free flap reconstruction of lateral skull base defects between 1999 and 2005 were therefore reviewed. Twelve consecutive patients (4 males, 8 females) with a mean age of 63 years (range, 39 to 74) underwent such reconstruction following resection of lateral (11 cases) and anterolateral (1 case) skull base lesions. Eight patients had squamous cell carcinoma, 3 had infection or osteoradionecrosis, and 1 had adenoid cystic carcinoma. The duration of surgery (from induction of anesthesia to exit from the operating room) averaged 14.5 hours (range, 10 to 19.5 hours). All donor sites were closed directly. All the flap transfers were successful, with minimal reconstructive and donor site morbidity. During the follow-up period (average, 18 months; range, 2-48 months), 2 patients died of metastatic disease, and another 2 died of other unrelated causes. The remaining 8 patients are alive and disease free. It is concluded that lateral arm and anterolateral thigh fasciocutaneous free flaps should be considered as viable reconstructive options for lateral skull base ablative defects.

RESUMEN

OBJECTIVE: To determine the prevalence and timing of onset of gaze-modulated tinnitus and increased sensitivity to noise in patients who had undergone translabyrinthine excision of a vestibular schwannoma. STUDY DESIGN: Retrospective questionnaire study. SETTING: University hospital departments of audiology and neurotology. PATIENTS: A cohort of 359 patients who had undergone translabyrinthine excision of a vestibular schwannoma in the period 1997 to 2003. INTERVENTION: Translabyrinthine excision of a unilateral sporadic vestibular schwannoma. MAIN OUTCOME MEASURES: Patient reports and visual analogue scale measures of the timing of onset of gaze-modulated tinnitus and the presence, timing of onset, and persistence of increased sensitivity to noise after surgery. RESULTS: Completed questionnaires were returned by 275 patients (77%), of whom 132 (48%) were men and 143 (52%) were women. Preoperative tinnitus was reported in 150 patients (55%). In 124 of these 150 (83%) the tinnitus persisted, and in 26 of 150 (17%) it abated. Of the 125 patients without preoperative tinnitus, 43 (34%) developed it postoperatively. In 167 (61%) patients of the total group of 275, postoperative tinnitus was reported. Gaze-modulated tinnitus was reported in 53 patients (19%). Somatic-evoked or -modulated tinnitus was reported in 38 patients (14%). In response to the question, "Did you notice being extra sensitive to noise after your operation?," 138 patients (50%) replied that they did. In 111 patients, this persisted. The onset of the modulation of tinnitus was distributed throughout the postoperative period, whereas the onset of increased sensitivity to noise was overwhelmingly in the first 2 months after surgery. CONCLUSION: Gaze modulation of tinnitus after vestibular schwannoma removal was identified in 19% of patients in this series. The onset data did not convincingly argue for any specific mechanism. The prevalence of increased sensitivity to noise is surprising and may represent central hyperacusis in response to unilateral deafferentation of the auditory system.

RESUMEN

OBJECTIVES: To evaluate preoperative hearing, dizziness, and tinnitus handicap in patients with unilateral vestibular schwannoma (VS). DESIGN: Prospective administration of the Hearing Handicap Inventory (HHI), Dizziness Handicap Inventory (DHI), and Tinnitus Handicap Inventory (THI), prior to surgical intervention. SETTING: A tertiary referral neuro-otology clinic. PARTICIPANTS: A total of 145 consecutive patients who were admitted for excision of their vestibular schwannomas between May 1998 and July 2002. MAIN OUTCOME MEASURES: HHI, THI, and DHI scores. RESULTS: HHI, THI, and DHI scores were all found to be significantly correlated. There was no significant association between tumor size and any of the questionnaire scores. When data were categorized to give a measure of handicap severity, 68% had mild to significant hearing handicap, 30% had mild to severe tinnitus handicap, and 75% had mild to severe dizziness handicap. Eighty-eight percent of patients had some handicap in at least one domain, and 23% had some handicap in all three domains. Seven percent of patients had severe or significant handicap in all three domains. CONCLUSIONS: A considerable proportion of patients with unilateral VS have hearing, tinnitus, and dizziness handicap. These patients should optimally be offered appropriate rehabilitation, something that is especially important as conservative management by "watch, wait, and rescan" becomes more common.

RESUMEN

OBJECTIVE: To evaluate the change in tinnitus handicap after translabyrinthine vestibular schwannoma excision. STUDY DESIGN: Prospective administration of the Tinnitus Handicap Inventory (THI) preoperatively and at 3 and 12 months postoperatively. SETTING: : A tertiary referral neuro-otology clinic. PATIENTS: A total of 149 patients from a series of 170 consecutive patients who had vestibular schwannomas excised between May 1998 and July 2002 and who had completed THIs preoperatively and at 3 and 12 months postoperatively. INTERVENTIONS: Translabyrinthine excision of a unilateral sporadic vestibular schwannoma. MAIN OUTCOME MEASURES: THI scores. RESULTS: The number of patients with moderate or severe handicap was 21 (14%) in the preoperative group and 21 (14%) in the 12-month postoperative group. No significant differences in group data were found comparing (by Wilcoxon signed rank test) preoperative data with 3 months postoperative data (p = 0.09), preoperative data with 12 months postoperative data (p = 0.09), and 3 months postoperative data with 12 months postoperative data (p = 0.33). Considering group data, tinnitus handicap is neither alleviated nor exacerbated by translabyrinthine surgery. The application of the validated 20-point criteria for significant change in the status of an individual patient indicates that tinnitus handicap was worse in 10 (6.5%), unchanged in 129 (87%), and better in 10 (6.5%). CONCLUSIONS: The findings of the current study can be used during preoperative patient counseling. In particular, the clinician is now able to take an informed and positive stance about the tinnitus handicap to be expected postoperatively.
