Vocal cord paralysis associated with anterior cervical fusion: considerations for prevention and treatment.

In a series of 375 patients with anterior cervical fusions, long-term follow-up results complete with laryngeal examination were obtained in 102 patients. One patient was found to have an inferior laryngeal nerve palsy, and one had a superior laryngeal nerve palsy. Both deficits were thought to be the result of surgical trauma. Measures to minimize the incidence of vocal cord paralysis include careful surgical technique and knowledge of the surgical anatomy of the laryngeal nerves. Suggestions are given for the assessment of postoperative hoarseness, and for the management of vocal cord paralysis.

Geniculate neuralgia: the surgical management of primary otalgia.

Intractable, unexplained deep-ear pain presents a rare, albeit significant problem in otolaryngological and neurosurgical practice. The authors review their experience with 18 cases of primary otalgia during the past 15 years. A total of 31 surgical procedures were performed. Seventeen patients had sequential rhizotomies and one patient had microvascular decompression alone. Based on the clinical diagnosis, the nerves sectioned were singly or in combination: the nervus intermedius (14 patients), geniculate ganglion (10 patients), ninth nerve (14 patients), 10th nerve (11 patients), tympanic nerve (four patients), and chorda tympani nerve (one patient). Microvascular decompression of the involved nerves was undertaken in nine patients, in whom vascular loops were discovered. Adhesions (six patients), thickened arachnoid (three patients), and benign osteoma (one patient) were other intraoperative abnormalities noted. The overall success of these procedures in providing pain relief was 72.2%, and the mean follow-up period was 3.3 years (range 1 month to 14.5 years). There was no surgical mortality. Expected side effects were: decreased lacrimation, salivation, and taste related to nervus intermedius nerve section, and transient hoarseness and diminished gag related to ninth and 10th nerve section. Four patients developed sequelae consisting of sensorineural hearing loss, vertigo, and transient facial nerve paresis. One patient had a cerebrospinal fluid leak and another developed aseptic meningitis as postoperative complications. Except when primary glossopharyngeal neuralgia is the working diagnosis, a combined posterior cranial fossa-middle cranial fossa approach is recommended for adequate exploration and/or section of the fifth, ninth, and 10th cranial nerves as well as the geniculate ganglion and nervus intermedius.

Surgical treatment of jugular foramen schwannomas.

Sixteen patients with schwannomas of the jugular foramen were operated on in the Department of Neurosurgery of the Nordstadt Hospital in Hannover, Germany, between 1986 and 1992. Patients with neurofibromatosis were excluded. The records of the 16 patients were retrospectively reviewed. There were five women and 11 men (mean age 43 years) with a symptom duration ranging from 6 months to 20 years (mean 5 years). The predominant symptoms were hearing loss, hoarseness, and cerebellar symptoms. Computerized tomography (CT), magnetic resonance (MR) imaging, and angiography were performed in all 16 patients. Depending on the radiological and surgical features, the tumors were classified into four types: Type A, a tumor primarily at the cerebellopontine angle with minimal enlargement of the jugular foramen (eight cases); Type B, a tumor primarily at the jugular foramen with intracranial extension (two cases); Type C, a primarily extracranial tumor with extension into the jugular foramen (one case); and Type D, a dumbbell-shaped tumor with both intra- and extracranial components (five cases). A retromastoid suboccipital craniectomy was performed for Type A tumors, and a combined cervical-mastoidectomy for Types B, C, and D. Total tumor removal was achieved in all cases. There was no operative mortality. Postoperative complications were cerebrospinal fluid leakage in one patient and mastoiditis in two patients. The follow-up period ranged from 12 to 42 months (mean 22 months). All patients were alive at the last follow-up review, and CT and/or MR imaging showed no tumor recurrence.

Banked fibula and the locking anterior cervical plate in anterior cervical fusions following cervical discectomy.

Eighty-eight consecutive patients underwent anterior cervical discectomy (ACD) with banked fibula fusion and internal fixation using the locking cervical plate. Pathology included cervical spondylotic radiculopathy in 48, cervical spondylotic radiculomyelopathy in 30, cervical facet dislocations with associated disc herniations in six, and autologous iliac crest graft collapse pseudoarthrosis with recurrent symptoms in four patients. Operations were single-level banked fibula fusion with plating in 37, multilevel banked fibula fusion with plating in 45, and combined single-level ACD banked fibula fusion with plating and posterior fusion in six patients. The only perioperative complication was transient hoarseness. There were no transfusions, infections, neurological injuries, or deaths. The mean time in the hospital for the nontraumatic cases was 1.8 days. The mean follow up was 22 months (range 12-30 months). There has been no motion at the fused level on flexion/extension films, no kyphosis, no screw plate backout, and no banked fibula has suffered graft collapse. Following a high-speed motor vehicle accident 6 months after a multilevel fusion, one alcoholic man suffered a fractured plate with transient worsening of neck pain, and the plate has remained in place for an additional 11 months of follow-up care. Compared to 100 consecutive autologous iliac crest fusions performed by the same surgeon, there were significantly fewer graft-related complications (p < 0.001). There was a significantly greater chance of autologous iliac crest collapsing with the passage of time as compared to banked fibula. Time until return to work was shorter by 5 weeks for the plate/banked fibula group (p < 0.05). When fusion is considered following ACD, the combination of banked fibula and locking cervical plates is significantly superior to autologous iliac crest grafts.

Revision of anterior cervical pseudoarthrosis with anterior allograft fusion and plating.

Anterior cervical discectomy and fusion is an efficacious procedure used to treat a variety of cervical spinal disorders, including spondylosis, myelopathy, herniated discs, trauma, and degenerative disc disease. Pseudarthrosis, or failure of fusion, may be the most common complication of spinal fusion procedures. Nineteen consecutive patients with symptomatic pseudarthrosis following failed anterior cervical fusions were treated with anterior cervical revision using iliac crest allografts and either the Cervical Spine Locking Plate system (10 patients) or the Trapezial Osteosynthetic Plate system (nine patients). The mean age of the nine men and 10 women undergoing treatment was 49.1 years (range 25-72 years). Eleven patients (57.9%) exhibited pseudarthrosis at one level, six (31.5%) at two levels, and two (10.5%) at three levels. The indications for revision were intractable neck pain with radiculopathy (17 patients) or myelopathy (two patients), with evidence of pseudarthrosis on plain cervical radiography as well as computerized tomography (CT) or single-photon emission computerized tomography (SPECT) scanning, or both. All eight patients evaluated with SPECT showed increased focal uptake consistent with pseudarthrosis, which was subsequently confirmed intraoperatively in all eight. The average follow-up period was 22.4 months (range 12-42 months). Solid osseous fusion was achieved over all 28 levels in all 18 patients available for follow-up review (100%). One patient died 4 months postoperatively from myocardial infarction related to preexisting coronary artery disease. There were no intraoperative complications; postoperatively, two patients (10.5%) experienced transient hoarseness. Anterior revision of failed cervical fusions using allograft interbody fusion material and anterior plating is a safe and efficacious procedure. In this series, the use of allografts avoided donor site morbidity without adversely affecting fusion rates. Rigid internal fixation was achieved by means of anterior plating without increasing surgical morbidity rates. The SPECT imaging technique has the potential to reliably confirm the diagnosis of pseudarthrosis.

Follow-up results of using microvascular decompression for treatment of glossopharyngeal neuralgia.

UNLABELLED: Glossopharyngeal neuralgia (GPN) is an uncommon disorder that is characterized by a severe lancinating pain commonly induced by swallowing. There has been some debate among various authors as to which surgical procedure should be adopted to treat cases of GPN: microvascular decompression (MVD) or partial rhizotomy. The latter necessitates the partial destruction of normal neural structures. OBJECT: The purpose of this paper is to present follow-up results in patients with GPN who underwent MVD. METHODS: Between 1980 and 1995, 20 patients underwent MVD for GPN. Results were studied to verify the effectiveness of MVD performed in 16 patients before 1991 who participated in follow-up evaluation for more than 5 years postoperatively. The follow-up period ranged from 5 to 16 years (mean +/- standard deviation 11.6 +/- 2.8 years). The method adopted for MVD was to reposition the offending vessel, such as a troublesome vertebral artery or posterior inferior cerebellar artery that is commonly ectatic and arteriosclerotic, by lifting the loop of the artery and using glue to affix it to the nearby dura mater of the petrous bone. CONCLUSIONS: Pain was relieved in all cases. Two patients complained of persistent mild hoarseness, causing the inability to speak loudly, and two patients complained of occasional coughing episodes that occurred for a couple of years after the surgery. No other complications were reported and no recurrence of pain was noted during the follow-up period. This procedure provided satisfactory results by preserving important perforating arteries in this area and by repositioning offending arteries in a safer and surer fashion, thus reducing complications and recurrence of GPN.

Cervical corpectomy: report of 185 cases and review of the literature.

OBJECT: This study was conducted to determine the indications, safety, efficacy, and complication rate associated with performing corpectomy to achieve anterior decompression of neural elements or for removing anterior lesions. METHODS: Between 1987 and 1998, 185 patients underwent cervical corpectomy for the treatment of degenerative spondylitic disease (81 cases), ossification of posterior longitudinal ligament (16 cases), correction of postoperative kyphosis (31 cases), trauma (39 cases), tumor (10 cases), and infection (eight cases). Ninety-nine patients presented with myelopathy, 48 with radiculomyelopathy, 24 with radicular pain, and 14 with neck muscle pain. Eighty-seven patients underwent a one-level corpectomy; 45 of these patients underwent a discectomy at a different level. Seventy patients underwent a two-level corpectomy; 27 of these patients underwent a discectomy at a different level. Twenty-eight patients underwent a three-level corpectomy. Autograft (iliac crest) was used in 141 cases and allograft (fibula) in 44 cases. All but six patients underwent fixation with an anterior plate-screw system. There were no operative deaths. During the procedure the vertebral artery was injured in four patients and preserved in two of them. No neurological sequelae were encountered. Postoperative hoarseness, transient dysphagia, and pain at the graft site were transitory and successfully managed. The fusion rate was 98.8%. Six patients experienced transient deterioration after surgery but they improved. No patient experienced permanent neurological deterioration and 160 (86.5%) improved. CONCLUSIONS: Corpectomy has an important role in the management of various degenerative, traumatic, neoplastic, or infectious disorders of cervical spine. Following treatment in this series, radiculopathy always improved and myelopathy was reversed in most patients.

Cadaveric fibula, locking plate, and allogeneic bone matrix for anterior cervical fusions after cervical discectomy for radiculopathy or myelopathy.

OBJECT: The authors have previously reported that the results of using cadaveric fibula and locking plate (CF/LP) fusion following anterior cervical discectomy (ACD) for cervical spondylotic radiculopathy and myelopathy are superior to those obtained using autologous iliac crest (AIC) grafts in the short term. The long-term results of using this construct are important in substantiating this improvement. The authors report on 246 consecutive patients (54% smokers) who underwent ACD with CF/LP fusion (175 with allogeneic bone matrix [ABM]) and compare them with 111 consecutive patients in whom AIC fusions (49% smokers) were performed by the same surgeons. METHODS: The study is a retrospective nonrandomized analysis, and chi-square statistics were used. Bone densitometric studies of AIC grafts and CF grafts were performed. A paired t-test was used for statistical analysis of the results. Disease in the group of patients undergoing CF/LP fusion included soft-disc herniation with radiculopathy in 14, soft-disc hemiation with myelopathy in seven, cervical spondylotic radiculopathy in 144, cervical spondylotic myelopathy in 75, AIC graft collapse pseudarthrosis in five, and ACD with no fusion collapse/kyphosis in one. Operations consisted of single-level CF/LP fusion in 142 patients and multilevel CF/LP fusion in 104. Perioperative complications in the CF/LP group included three cases of transient hoarseness. There were no transfusions, infections, neurological injuries, or deaths. The mean hospital length of stay was 1.2 days (28% outpatient and 66% 23-hour stay). The mean follow-up period was 60 months (range 12-94 months). Ten patients were lost to follow up after 1 year. Long-term complications included one traumatic plate fracture and one symptomatic pseudarthrosis with plate fracture. At 1 year and beyond, in 245 (99.6%) of 246 patients radiographically documented fusion with no motion at the fused level on flexion-extension films was demonstrated. There was no kyphosis, no symptomatic screw plate backout, and no CF/LP graft collapse (100% in the ABM group). In the 111 consecutive patients with AIC fusions, however, there was a 17% graft-related complication rate. There were significantly fewer graft-related complications in the CF/LP group (p < 0.001). There was no difference in neurological outcome for any of the groups. In the groups undergoing single-level ACD there was a significantly greater chance of complete relief of neck pain CF/LP fusion compared with those undergoing AIC fusion (p < 0.02). There was a significantly greater chance of AIC collapse with the passage of time compared with CF graft (p < 0.02). Time until return to work was shorter for the CF/LP group by 5 to 6 weeks (p < 0.02). There was a higher rate of radiographically documented pseudarthrosis in the AIC group (p < 0.006). The mean bone densitometry for the CF/LP group was 0.7 g/cm2, significantly greater than that of the AIC group, which was 0.2 g/cm2 (paired t-test p < 0.001). CONCLUSIONS: When fusion is necessary following ACD, the results of CF/LP fusion are significantly superior in the first 5 years after surgery compared with those for AIC fusions. It remains to be determined if demineralized ABM has a significant effect in enhancing fusion.

Combined occurrence of hyperthyroid Graves' and Hashimoto's thyroiditis.

A 40 years old, married Govt. servant from Sadar upazila, Mymensingh was admitted in Mymensingh Medical College Hospital on 9(th) February, 2005 with the complaints of excessive sweating for 1 year, gradual loss of weight for 6 months, swelling in front of the neck for 1(1/2) months, and hoarseness of voice for 1 month. He was nervous, irritable, emotionally labile. Thyroid gland was symmetrically enlarged, firm in consistency with scalloped surface. Palms were warm and sweaty with fine tremor in outstretched hands. Lid lag, lid retraction and proptosis were the occular manifestations. All the reflexes were exaggerated. Radioactive iodine uptake showed enlarged gland with homogenously increased radiotracer concentration, ultrasonogram findings were enlarged gland with hypoechoic parenchyma with fibrous septa, T(3), T(4), TSH values were 6.56 nmol/L, 241.09 nmol/L and 0.14 mIU/L respectively. Thyroid microsomal antibody level was 32.87%. Thyroid FNAC findings were sheets of regular follicular cells, some large cells with granular basophilic cytoplasm, macrophages, a few inflammatory cells and giant cells. All the above findings were in favour of a diagnosis of hyperthyroid Graves' with Hashimoto's thyroiditis.

A case of Farber lipogranulomatosis.

A 35 month old girl had suffered from painful joint contractures of the whole body since a few months after birth, and she gradually developed numerous periarticular and subcutaneous nodules, hoarseness, swallowing difficulty with recurrent respiratory infections, nystagmus, and mental and developmental retardation. She was misdiagnosed as having juvenile rheumatoid arthritis at several university hospitals. Serologic studies for rheumatoid arthritis were all negative. Radiologic findings of the whole body showed osteoporosis and bony erosions; on brain CT the brain was diffusely atrophied. On cine-esophagography barium refluxed into the nasopharynx. Light microscopically, the reticular dermis and subcutis were markedly thickened with hyalinized sclerotic collagen bundles. There were interstitial and perivascular aggregates of foamy histiocytes which were positive for CD-68 immunostaining. On electron microscopy, foamy histiocytes were packed with numerous membrane-bound inclusions having C-shaped or worm-like profiles in addition to many myelin figures, occasional lipid droplets and rare banana-like bodies.

Oropharyngeal angioedema induced by inhaled histamine.

Inhaled histamine used to measure airway responsiveness produces some side effects more frequently than does methacholine. It is possible that the inhaled histamine induces the side effects in asthmatics with increased end organ responsiveness to histamine. A 56-yr-old woman with chronic idiopathic angioedema presented with asthma-like symptoms. Methacholine challenge test was performed, with a negative result. Five days later, histamine inhalation test was done. FEV1 fell by 37% after inhalation of histamine concentration of 8 mg/mL. Immediately thereafter, severe angioedema on face, lips, and oropharyngeal area, foreign body sensation at throat, and hoarseness occurred. To assess end organ responsiveness to histamine, skin prick tests with doubling concentrations of histamine (0.03-16 mg/mL) were carried out on the forearm of the patient and six age- and sex-matched asthmatic controls. The wheal areas were measured. The patient showed greater skin responses than the controls. Regression analysis showed that the intercept and slope were greater than cut-off levels determined from six controls. The patient showed an increased skin wheal response to histamine, indicating the enhanced end organ responsiveness to histamine, which is likely to contribute to the development of the oropharyngeal angioedema by inhaled histamine.

Transhiatal gastric transposition of a long gap esophageal atresia.

Transhiatal gastric transposition was performed in a long gap esophageal atresia without tracheoesophageal fistula. The patient was a 12 months old female infant with previous stamm-type gastrostomy. The stomach was mobilized preserving the right gastric artery, the right gastroepiploic artery and spleen. The proximal and distal blind pouches of esophagus were excised by transcervical and transhiatal route, respectively. The mobilized stomach was pulled up into the neck through esophageal hiatus and posterior mediastinal route. The esophagogastrostomy, the only one anastomosis of this procedure, was safely performed in the neck. There were neither anastomotic leak nor early anastomotic stricture. The oral feeding was quickly established. There was no clinical evidence of regurgitation, difficulty of gastric emptying, hoarseness or respiratory problem. The low morbidity combined with satisfactory functional result indicates that the transhiatal gastric transposition is a safe and easy alternative surgical procedure for esophageal replacement in long gap esophageal atresia.

Scleroderma-like manifestation in a patient with primary systemic amyloidosis: response to high-dose intravenous immunoglobulin and plasma exchange.

A 54-year-old Korean male with scleroderma-like manifestation of primary systemic amyloidosis presented with firm cutaneous induration of face and distal extremities, subcutaneous induration of the trunk and proximal extremities, limited range of motion in all joints, hoarseness, and dysphagia. Monthly high-dose intravenous immunoglobulin (hdIVIg) was given (three treatments, each time administering 0.4 g/kg per day for five days), and both signs and symptoms began to improve. However, the quantitative analyses of serum protein did not improve. Therapeutic plasma exchange (TPE) was performed monthly to clear the elevated serum immunoglobulin, and after several treatments, their levels normalized and symptoms were maintained in the improved state for more than two years. To summarize, hdIVIg and TPE combination therapy may be used as a safe first-line treatment for patients with primary systemic amyloidosis presenting with symptomatic monoclonal gammopathy.

[Total thyroidectomy with a modified Miccoli's approach for treatment of Graves' disease--feasibility and its applying techniques].

OBJECTIVE: To assess the feasibility and relevant applying techniques of total thyroidectomy for Graves' disease with a modified Miccoli's approach. METHODS: Forty-two patients with Graves' disease consecutively received the radical operation from June 2002 to December 2004.The modification includes: (1) Incision extending according to the degree of lobe enlargement (3-6 cm, average 4 cm); (2) A space maintain-regulating device was used to change dimensionally the volume of working space (mainly height) when specific manipulation needed; (3) A volume-reducing resection step was performed for the gland with degree III hyperplasia by cutting off the middle-inferior part of the lobe prior to endoscopic lobectomy. The approach was designed to mainly use ultrasonically-activated scalpels, with suction-dissector or others as supplementary instruments. During the operations, a method of "sequenced dissect-coagulate-cut" was employed to directly divide all branches of thyroid vessels without ligation or application of hemoclips. RESULTS: All procedures were completed successfully. None of them were converted to open surgery due to uncontrolled bleeding or severe postoperative hematoma. No severe complications occurred, except 2 cases who suffered from temporary hoarseness. CONCLUSION: Total thyroidectomy for Graves' disease can be safely performed with the modified Miccoli's approach by using ultrasonic scalpel and the space maintain-regulating device. Application of these adaptive reforms can obviously reduce the difficulties in manipulation, and thus, make the usage of this minimally invasive design also clinically possible for even radical treatment of the gland.

Is this lump in the neck anything to worry about? .

Neck masses are common and often the result of self-limited inflammation or infection. Congenital masses and neoplasms are additional benign causes. However, a neck mass can signal a malignant tumor, so it is important to understand what represents an abnormal mass and to recognize warning signs and symptoms. Patients at risk of serious clinical problems may be identified through findings on history taking (e.g., progressive enlargement of the mass, prolonged hoarseness) and physical examination (e.g., unilateral nasal obstruction, intraoral induration). Suspicion of a malignant process calls for referral to a subspecialist in head and neck disorders.

Recognizing atypical manifestations of GERD. Asthma, chest pain, and otolaryngologic disorders may be due to reflux.

The presence of common symptoms, such as heartburn and regurgitation, usually make the diagnosis of gastroesophageal reflux disease (GERD) fairly straightforward. However, extraesophageal symptoms of GERD, such as asthma, noncardiac chest pain, and hoarseness, are often not recognized and therefore are poorly managed. This article sheds light on the atypical manifestations of GERD as well as current approaches to diagnosis and treatment.

A patient with primary squamous cell carcinoma of the thyroid intermingled with follicular thyroid carcinoma that remains alive more than 8 years after diagnosis.

Primary squamous cell carcinoma of the thyroid is an extremely rare tumor with a highly aggressive clinical course. We report here on a patient with primary squamous cell carcinoma of the thyroid who remains alive more than 8 years after diagnosis. A 56-year-old man presented with a hoarse voice and a rapidly progressing mass on the right side of the thyroid gland. The patient underwent a total thyroidectomy without neck lymph node dissection. Histopathologic findings revealed primary squamous cell carcinoma combined with follicular carcinoma of the thyroid. The tumors metastasized to the cervical lymph nodes, thoracic spine and lung. He underwent 5000 rads of adjuvant radiotherapy to the neck. TSH suppressive therapy with L-thyroxine was administered alone rather than radioactive iodine therapy or chemotherapy. The patient's clinical course has been remarkable over the first 7 years; he has remained stable except for a transient paraplegia due to nerve compression. The patient underwent colectomy for the diagnosis of a colon cancer. Recent evaluation has revealed a new lesion in the lung; this was diagnosed as metastatic follicular carcinoma originating from the thyroid. High dose radioactive iodine therapy was administered, and he remains alive in stable condition.

[Analysis of pathological vocal fold vibrations using high-speed digital imaging].

There have been various methods devised to monitor vocal fold vibration. Stroboscopy provides clinically-celevant information concerning pathology of the vocal folds. However, slow motion observation is based on the regularity of the vibration, and this ignores the role of irregularity of the vocal fold vibration in pathological cases. In order to know more about the nature of the vocal fold vibratory pattern, it is essential to monitor the vibration on a cycle by cycle basis. We analysed vocal fold vibrations of 22 pathological larynges using a computer-assisted high-speed digital imaging technique. Observed items included symmetry, regularity, phase difference, glottal closure, amplitude, mucosal wave and periodicity difference. Vibratory patterns were classified by location of lesion, severity of disease, expiratory pressure and laryngeal modulation. Analyses of pathological vocal fold vibrations using high-speed digital imaging techniques are providing the theoretical support for voice therapy and elucidating the causes of hoarseness.
