Porencephalic cyst: a review of the literature and management of a rare cause of cerebrospinal fluid otorrhea.

OBJECTIVE: To discuss the first reported case of spontaneous cerebrospinal fluid (CSF) otorrhea caused by a massive CSF-containing porencephalic cyst. STUDY DESIGN: A case report and review of the literature (MEDLINE 1962-2005). SETTING: A tertiary neurotologic referral center. PATIENT: A 65-year-old woman with congenital hemiplegia presented with left-sided spontaneous CSF otorrhea of 4-month duration. An audiogram revealed a mixed hearing loss. High-resolution computed tomography revealed a thinning of the tegmen and epitympanum without an obvious defect. Magnetic resonance imaging revealed a massive porencephalic cyst essentially replacing the entire left cerebral hemisphere. INTERVENTION: A transmastoid approach with three-layered closure was used to successfully repair the sieve-like defects that were discovered in her tegmen. RESULTS: The patient remains free of drainage, and the conductive hearing loss has resolved. CONCLUSION: Spontaneous CSF otorrhea caused by a porencephalic cyst is an uncommon cause of conductive hearing loss that has never been reported before. Only a few cases of traumatic CSF otorrhea/rhinorrhea associated with a porencephalic cyst have been reported. A high level of suspicion, a beta2-transferrin assay, and appropriate radiographic imaging are required for diagnosis in adults without a history of trauma, meningitis, chronic ear disease, or previous ear surgery.

Revision facial nerve surgery.

Transection of the facial nerve can result from blunt or penetrating trauma to the face or temporal bone. It can also occur accidentally during surgery, or as a planned surgical procedure carried out in the interest of eradicating disease. If transection is recognized at surgery, direct anastomosis or cable grafting is the procedure of choice. This article presents two cases with neither clinical nor electrical evidence of recovery. The authors review current understanding of the changes that occur in the neuron, axon, and muscle after injury to the nerve and the underlying pathology that led to graft failure in these cases. They also evaluate surgical options and diagnostic test results that help in selecting appropriate surgical procedures.

Headache: a quality of life analysis in a cohort of 1,657 patients undergoing acoustic neuroma surgery, results from the acoustic neuroma association.

OBJECTIVES: On the basis of survey results of the Acoustic Neuroma Association (ANA), we report patient ratings of postoperative headache (POH) symptoms, determine its effect on quality of life (QOL), and review the literature regarding POH after acoustic neuroma (AN) treatment. STUDY DESIGN: In this cohort study, 1,657 patients who underwent surgical treatment of AN reported their experiences of POH. METHODS: A detailed questionnaire was mailed to members of the ANA to identify preoperative and postoperative headache symptoms, complications, and long-term effects on physical and psychosocial function. Questions were answered by 1657 (85.4%) respondents that were intended to qualify and quantify the effects of POH, including QOL issues. Responses were analyzed by tumor size, surgical approach, and patient age and sex. Statistical analysis was performed with the SPSS software. RESULTS: Preoperative headache was reported in approximately one third of respondents. Typical POHs occurred more than once daily (46%), lasted 1 to 4 hours in duration (43.1%), and were of moderate intensity (62.6%). The worst headaches were rated as "severe" by 77% of respondents. Treatment most often reported for typical headaches were nonprescription medications including nonsteroidal anti-inflammatory drugs in 61.3% (P < .01) and regular use of narcotics in 15%. Patients who underwent the retrosigmoid approach were significantly more likely to report their worst POH as "severe" (82.3%) compared with the translabyrinthine (75.2%) and middle fossa approaches (63.3%). Women and younger patients tended to have poorer outcomes with regard to POHs. CONCLUSIONS: In this large cohort study of AN patients, POH was a significant morbidity among AN patients with persistent headaches. Treating physicians should be aware of the risk factors identified and the effect POH has on the QOL when counseling patients regarding optimal treatment management.

Facial paralysis and surgical rehabilitation: a quality of life analysis in a cohort of 1,595 patients after acoustic neuroma surgery.

OBJECTIVES: On the basis of survey results of the Acoustic Neuroma Association, we report patient ratings of facial dysfunction and outcomes for various facial rehabilitative therapies after surgical treatment of acoustic neuroma (AN). We assessed patients' perceived quality of life (QOL) and reviewed the literature regarding facial dysfunction and its management associated with AN. STUDY DESIGN: The Acoustic Neuroma Association mailed a detailed questionnaire to 2,372 members to identify preoperative and postoperative symptoms, complications, and long-term effects on physical and psychosocial function. A cohort of 1,595 (82.2%) respondents who underwent surgical treatment of ANs reported their experiences with facial dysfunction. PATIENTS: Of all 1,940 survey respondents, 1,682 of 1,875 that had ANs underwent surgical treatment. The study included 1,595 patients with ANs (82.2% of all respondents) who underwent surgical treatment by way of the translabyrinthine, suboccipital, or middle fossa approaches and excluded 87 respondents who did not report the type of surgical approach. METHODS: Respondents answered questions intended to qualify and quantify the degree that facial dysfunction impacted QOL parameters. Responses were analyzed for tumor size, surgical approach, patient age, and sex. Statistical analysis was performed using SPSS software. RESULTS: In our analysis, 11% of all respondents experienced some degree of preoperative facial weakness or eye problems. Of all respondents, 45.5% (725 patients) experienced worsened facial weakness caused by surgery, and of these, 72% reported that it was permanent. The most commonly used successful therapy for facial reanimation for 271 (19.6%) patients was placement of a gold weight. The factor most often associated with poor outcome was a large tumor. Of all respondents, 28% felt significantly affected by facial weakness, 63% felt their smile was symmetric, and 70% were content "quite a bit" or "very much" with their QOL. CONCLUSIONS: In this large cohort study of AN patients, facial dysfunction was a significant morbidity. Physicians should be aware of the risk factors identified, specifically large tumor size and the impact facial dysfunction has on QOL, when counseling patients regarding optimal management of AN.

Patient perception of comorbid conditions after acoustic neuroma management: survey results from the acoustic neuroma association.

OBJECTIVES/HYPOTHESIS: Based on survey results of the Acoustic Neuroma Association, the patient ratings of the most difficult aspects of acoustic neuroma management were reported and a review of the literature was made regarding comorbid conditions associated with acoustic neuroma treatment and their impact on patient quality of life. STUDY DESIGN: Cohort study of 1940 patients who were members of the Acoustic Neuroma Association. METHODS: A detailed questionnaire was mailed to 2372 members of the Acoustic Neuroma Association to identify preoperative and postoperative symptoms, complications, and long-term effects on physical and psychosocial function. For 1940 respondents (81.8%) who reported the "most difficult aspect of the AN [acoustic neuroma] experience," the responses were analyzed by tumor size, surgical approach, and patient age and sex. Statistical analysis was performed using SPSS software. RESULTS: Respondents reported that the most difficult aspect of the acoustic neuroma experience was hearing loss (25.8%), followed by facial weakness (17.9%), eye problems (10.8%), and headache (10.5%). In order of frequency, men reported hearing loss, balance problems, perioperative surgical experience, and eye and facial weakness, and women reported hearing loss, facial weakness, eye problems, and headache. Facial weakness was a morbidity more often reported for men and women who had large tumors, who were young, or who had undergone the retrosigmoid approach. Balance dysfunction was significant in patients older than 75 years of age. In patients with small tumors, headaches and balance problems were frequently reported. CONCLUSION: In the large cohort study of patients with acoustic neuroma, perceptions regarding the impact of treatment illustrated why it is incumbent on physicians to understand the sentiments of patients with acoustic neuroma when counseling them and recommending optimal management strategies.

Recurrent advanced (T3 or T4) head and neck squamous cell carcinoma: is salvage possible?

BACKGROUND: Salvage surgery is often the only curative option for recurrent cancer. In patients whose initial tumor is stage T3 or T4, the primary therapy often makes salvage even more difficult. We therefore analyzed the outcome in patients who were originally treated for T3 or T4 squamous cell carcinoma of the oral cavity, larynx, oropharynx, or hypopharynx and who then had a recurrence and chose to undergo further therapy for cure. PATIENTS AND METHODS: From 1980 to 2000, a total of 940 patients were treated for stage T3 or T4 cancer. Forty-eight patients underwent salvage therapy for recurrence: 24 for primary site recurrence, 20 for regional recurrence, and 4 for locoregional recurrence. RESULTS: The mean time to recurrence was 14.0 months, and the mean survival time was 26.2 months. Among the 28 patients treated for primary site recurrence, the mean time to rerecurrence was 12.6 months, and the mean survival time was 27.3 months. Only 5 of the 28 patients had prolonged survival. The stage of the recurrent disease did not influence outcome. Among the 20 patients treated for neck recurrence, the mean time to recurrence was 14.0 months, and the mean survival time was 25.0 months. Six of the 20 patients had prolonged survival, but none had a recurrence in a previously dissected and irradiated neck. CONCLUSIONS: These results show the limited potential for survival in patients who have a recurrence after treatment for advanced primary site head and neck cancer. Patients who have not undergone all modalities of therapy have the potential for salvage, but even then the chances are limited. Given the morbidity of salvage therapy, and the limited chance for cure, physicians must cautiously counsel patients who are contemplating treatment of recurrent cancer after therapy for advanced disease.
