RESUMEN

Seventy-eight patients participated in this multicenter, third-party-blinded study comparing a single daily dose of azithromycin for 5 days (500 mg on day 1 followed by 250 mg/day for days 2-5) with amoxicillin (500 mg three times daily) for 10 days in the treatment of acute bacterial maxillary sinusitis. A total of 38 evaluable patients contributed to the efficacy analysis. The overall clinical response rate was 100% for both antibiotics. The clinical cure rate, as determined by the investigator, was 73.9% for azithromycin and 73.3% for amoxicillin; improvement was seen in 26.1% and 26.7% of patients, respectively. The bacteriologic cure rate in these 38 patients was 100% in both groups. Both antibiotics were well tolerated; side effects were reported by 4.9% of patients in the azithromycin group compared with 8.1% in the amoxicillin group. Most of these side effects were gastrointestinal disturbances that were reported by four of five (three amoxicillin, one azithromycin) patients experiencing side effects. All side effects were mild, and in both groups only minor abnormalities in laboratory data were detected. No patient discontinued the study because of treatment-related side effects. In this study, a 5-day course (one dose per day) of azithromycin proved to have efficacy, safety, and tolerability that was equal to a 10-day course (three doses per day) of amoxicillin in the treatment of acute bacterial sinusitis.

RESUMEN

OBJECTIVE: To describe the clinical features, causes, imaging characteristics, treatment, and outcome of patients with the acquired immunodeficiency syndrome (AIDS) and sino-orbital aspergillosis. DESIGN: Records of 5 patients were reviewed. Results of imaging and histopathologic examinations and clinical courses of the patients were studied. RESULTS: There were 3 women and 2 men (mean age, 34.0 years). All had received a diagnosis of AIDS, and mean CD4+ cell count was 0.014 x 10(9)/L (14 cells/mm3). Computed tomographic scanning exhibited heterogeneous, enhancing sino-orbital soft tissue lesions with bony erosion, and magnetic resonance imaging disclosed soft tissue masses hypointense on T1- and T2-weighted images. The infection involved 1 or more paranasal sinuses, with extension into the right orbit in 3 patients and into the left orbit in 2. Patients were treated with aggressive surgical debridement and intravenous antifungal agents. In addition, local irrigation of amphotericin B was performed in 3 patients. Aspergillus fumigatus was found to be the cause in all 5 patients. Intracranial extension developed in 4 patients, and all subsequently died. The 2 longest surviving patients were the only ones being treated with protease inhibitors. Three patients had a history of frequent marijuana smoking. CONCLUSIONS: Sino-orbital aspergillosis is a progressive, relentless, and usually fatal opportunistic infection of advanced AIDS. Patients are first seen with long-standing headache and proptosis with minimal external inflammatory signs. Marijuana smoking may increase the risk for development of sino-orbital aspergillosis in these patients. Aggressive surgical and medical treatment, combined with newer combination therapies using protease inhibitors, may improve the longevity of these patients.

RESUMEN

Electrical stimulation of the vagus nerve has shown efficacy in controlling seizures in experimental models, and early clinical trials have suggested possible benefit in humans. Eleven patients with complex partial seizures were subjected to implantation of vagus nerve stimulators. Electrode contacts embedded in silicone rubber spirals were placed on the left vagus nerve in the low cervical area. A transcutaneously programmable stimulator module was placed in an infraclavicular subcutaneous pocket and connected to the electrode. One patient required replacement of the system due to electrode fracture. Another patient developed delayed ipsilateral vocal-cord paralysis; the technique was then modified to allow more tolerance for postoperative nerve edema. A third patient showed asymptomatic vocal-cord paresis on immediate postoperative laryngoscopy. Vagus nerve stimulation produces transient vocal-cord dysfunction while the current is on. Nine patients were randomly assigned to receive either high- or low-current stimulation, and seizure frequency was recorded. The high-current stimulation group showed a median reduction in seizure frequency of 27.7% compared to the preimplantation baseline, while the low-current stimulation group showed a median increase of 6.3%. This difference approached statistical significance. The entire population then received maximally tolerable stimulation. The high-current stimulation group showed a further 14.3% reduction, while the low-current stimulation group showed a 25.4% reduction compared to the blinded period. The efficacy of vagus nerve stimulation seemed to depend on stimulus parameters, and a cumulative effect was evident. These results are encouraging, and further study of this modality as an adjunct treatment for epilepsy is warranted.

RESUMEN

HYPOTHESIS: The medial orbital floor (MOF) and adjacent bony ridge of the antrostomy, when combined with columellar measurements, are easily identifiable and consistent anatomic reference points from which critical orbital and skull base structures can be found during endoscopic sinus surgery. METHODS: Two examiners, with varying endoscopic sinus surgery experience, performed endoscopic and direct measurements from the columnella and medial orbital floor to critical orbital and skull base structures on 11 human cadaver heads (18 sides). The distances to four critical skull base or orbital structures and to the anterior and posterior wall of the sphenoid sinus were measured. The mean, ranges, and standard deviations for all measurements (endoscopic and direct) were calculated and simple regression analysis was performed. RESULTS: The mean and range of values for each of the variables correlated well between examiners, and between endoscopic and direct measurements. There was slightly more variability in measurements when the MOF was used. However, the differences were no more than a few millimeters and did not appear to affect the overall clinical use of these values. CONCLUSIONS: The MOF and adjacent bony ridge of the antrostomy, when combined with columellar measurements, are easily identifiable and consistent anatomic landmarks that are not affected by the presence of significant inflammatory disease or previous surgery. These reference points provide even the most inexperienced surgeon with precise anatomic localization within the paranasal sinuses. They also determine the correct anteroposterior trajectory into the sphenoid sinus, whereby inadvertent intracranial or intraorbital complications may be avoided.

RESUMEN

OBJECTIVE: To determine the efficacy of computed tomographic image-guided endoscopic surgery in the hands of inexperienced surgeons. STUDY DESIGN: Four second-year otolaryngology residents, with no prior experience performing ethmoidectomies, performed endoscopic sinus surgery (ESS) on formalin-fixed human cadaveric specimens with and without the aid of computer-assisted surgery (CAS). METHODS: Each resident was asked to identify critical sinus, orbital, and skull base structures while performing a total ethmoidectomy and multiple sinusotomies. Their surgical accuracy (percentage of correctly identified structures), total operative time, and incidence of major complications were recorded for each side. A total of 16 sides were evaluated (8 with and 8 without CAS). Statistical significance between groups was determined by means of Pearson's chi2 analysis. RESULTS: Statistical analysis showed a significant difference (P = .001) in the mean accuracy of identifying critical anatomical landmarks between the CAS (97%) and non-CAS (76.8%) groups. Although not statistically significant, operative time appeared to be longer in the group using CAS (average of 67 vs. 80 min). Three major intracranial complications were documented only in the group not using CAS. CONCLUSIONS: Although, unquestionably, a thorough knowledge of the anatomy remains essential for performing ESS, CAS improves surgical accuracy and reduces the risk of major intracranial or intraorbital complications for residents. In additional, our data suggest that this technology may enhance surgical efficiency and improve the learning curve by reducing operative time (below one's normal baseline) while maintaining a greater than 90% accuracy in identifying critical anatomical landmarks.

RESUMEN

Detrimental effects of the natural aging process on the human cricoarytenoid joint have been hypothesized as a possible etiology for the voice changes seen in the aging population. Cellular events occurring at the histologic level, such as cricoarytenoid joint erosion or arthritis may lead to alterations in laryngeal structure which ultimately affect its function and performance. Seven normal human larynges of varying ages ranging from 29 to 69 years of age were examined histopathologically for changes in the cricoarytenoid joint. The synovium, joint space, periarticular muscle, and respiratory epithelium were evaluated for the presence of inflammatory changes or edema and degree of vascularity. The location and amount of ossification, elastin, and collagen formation were also noted. There were no appreciable changes noted in the synovium or joint space itself with increasing age. No differences were observed in the degree of elastin or collagen formation. However, there was progressive cricoid and arytenoid ossification and periarticular muscular atrophy and fibrosis. These findings suggest that other laryngeal changes may play a greater role in determining senescent vocal quality rather than changes within the cricoarytenoid joint itself.

RESUMEN

OBJECTIVES: The efficacy and safety of intraluminal Wallstent Endoprosthesis (Boston Scientific/ Medi-Tech, Quincy, MA) placement to restore airway patency in patients with tracheal stenosis or tracheomalacia are unknown. STUDY DESIGN: Retrospective review in setting of tertiary, referral, and academic center. METHODS: A retrospective review of 13 consecutive patients over a 2-year period who underwent transoral resection of tracheal stenosis and immediate transoral Wallstent placement. One patient had tracheomalacia. All of the patients were considered at high risk for transcervical surgery or had failed prior traditional open procedures. RESULTS: The average patient age was 54.2 years, with nine male and four female patients. All had Cotton/Myer stenoses (grades II to IV) with moderate to severe degrees of inspiratory stridor. Four patients were tracheotomy dependent. The length of stenosis varied from 1 to 4 cm. One patient had a 10-cm segment of tracheomalacia. At the time of writing, none of the patients has had a problem with significant migration or extrusion and most of the patients have incorporated the stent well without any short-term obstructive granulation tissue. After a mean follow-up of 15 months (range, 4-24 mo). 10 of the 12 patients with stenosis (83%) have remained free of any inspiratory noise during breathing. The one patient with tracheomalacia also has remained free of symptoms. CONCLUSIONS: Transoral Wallstents appear to be safe and may be a reasonable alternative in the restoration of airway patency in select patients with tracheal stenosis or tracheomalacia.

RESUMEN

This study investigated longitudinal changes of vocal efficiency and stability after primary thyroplasty type 1. Fifty-three patients with unilateral vocal-fold paralysis underwent vocal-function evaluation preoperatively and at periodic intervals of 1, 3, and 6 months postoperatively. Vocal-function assessment included videostrobolaryngoscopic examination, acoustical and aerodynamic analysis, and perceptual judgment of voice characteristics. Parameters that included glottic-gap size, maximum phonation time, glottic-flow rate, jitter, harmonic/noise ratio, breathiness, hoarseness, loudness, and phrasing showed significant improvement after thyroplasty and remained stable as early as 1 month postoperatively, with only slight fluctuations over a 6-month period. Postoperative voice outcome was not affected by age, sex, duration of vocal symptoms, cause of paralysis, or preoperative pulmonary function.

RESUMEN

Forty-two cases of inverting papilloma of the nose and paranasal sinuses were reviewed from 1972 to 1989. Forty-one patients underwent surgical excision. Of those patients followed up for at least 6 months, lateral rhinotomy was performed in 14 patients and midfacial degloving in 9 patients. The recurrence rates were 29% and 22%, respectively. The other 10 patients underwent excision through an external ethmoidectomy, Caldwell-Luc operation, or intranasal approach. There were five patients (12%) diagnosed with squamous cell carcinoma associated with inverting papilloma. The correlation of malignancy with proptosis, visual changes, infraorbital hypesthesia, and skull base involvement on presenting symptomatology is noted. Inverting papilloma is a benign neoplastic lesion that shows variable aggressiveness. A computed tomography (CT) scan evaluation is very important for the work-up. An aggressive wide surgical excision is best performed through an open approach. The approach for surgical removal should be based on the location and extension of the lesion. A graduating approach from a lesser to a more major excision is advocated even though a risk exists of having to reoperate in about one fifth of the patients who experience a recurrence. A secondary surgical excision, even with craniofacial resection, is essential to eradicate disease in cases of recurrence. Close follow-up is necessary. Further surgery may be indicated. Post-operative radiation therapy is recommended if malignancy is indeed present.

RESUMEN

OBJECTIVES/HYPOTHESIS: The diagnosis of acute bacterial rhinosinusitis continues to generate controversy in critically ill patients. The efficacy of endoscopically directed cultures in these patients is unknown. We compared antral tap (AT) with endoscopic tissue culture (ETC) of the osteomeatal complex in an intensive care unit (ICU) setting. METHODS: Twenty patients admitted to a surgical/trauma ICU were evaluated by AT and ENB for the presence of rhinosinusitis. All patients had 1) a fever of unknown origin without resolution on empiric antibiotic therapy for > or =48 hrs; 2) other sources of fever ruled out; 3) computed tomography scan evidence of mucoperiosteal thickening +/- sinus air/fluid levels; and 4) attempt at conservative treatment with topical decongestants and removal of all nasal intubation. Microbiologic data were collected and analyzed for any statistical difference between groups. RESULTS: A total of 29 sides underwent simultaneous tap and endoscopically directed tissue culture. The mean age was 40 years (range, 23-77 y) with 85% being males. Fifteen of 20 (75%) patients in the AT group were culture-positive. Of the 49 isolates from the AT, 55% yielded Gram-negative bacilli (Acinetobacter sp. 37%) and 45% yielded Gram-positive cocci. The ETC group was culture-positive in 18 of 20 (90%) patients. Of the 52 isolates from the ETC, Gram-negative bacilli were found in 58% (Acinetobacter sp. 33%) and 42% yielded Gram-positive cocci. The ETCs were culture-positive in all but 1 patient with positive taps. There appeared to be a concordance between AT and ETC in 60% of the patients. In five instances (25%), results of the AT or ETC changed ICU management. Two patients ultimately required sinus surgery. CONCLUSIONS: Sinus taps and/or endoscopically directed tissue cultures led to a change in ICU care in 25% of ICU patients studied. In patients with fever of unknown origin and computed tomography evidence of sinusitis, an antral tap continues to provide important information concerning maxillary sinusitis. However, ETC may give as good a representation of the microbiology and secondary inflammatory changes responsible for bacterial ICU rhinosinusitis causing fever of unknown origin. Further study on a larger group of patients is needed.

RESUMEN

OBJECTIVE: To determine whether cricopharyngeal myotomy can improve dysphagia associated with head and neck cancer surgery. DESIGN: Prospective, randomized, multicenter trial. SETTING: Twelve clinical sites across the United States. PATIENTS: Between 1989 and 1994, 125 patients undergoing combined modality therapy for head and neck cancer, including resection of the tongue base or supraglottic larynx, were prospectively entered into the trial. INTERVENTION: Cricopharyngeal myotomy on a randomized basis. MAIN OUTCOME MEASURES: Videofluoroscopic examination to determine oropharyngeal swallowing efficiency, which is defined as the ratio of percentage of the bolus swallowed to total swallowing time using 3 different bolus consistencies. RESULTS: No significant difference in oropharyngeal swallowing efficiency between myotomy vs no myotomy was seen at 6 months of follow-up regardless of bolus consistency. CONCLUSIONS: In this prospective test of cricopharyngeal myotomy, the procedure fails to significantly improve dysphagia associated with head and neck cancer surgery. The efficacy of this surgical procedure in other disease entities should also be rigorously explored.

RESUMEN

Seventeen patients were entered into a Phase I/II trial of concurrent hyperfractionated radiation therapy (7,440 cGy total dose; 120 cGy b.i.d.) combined with constant infusion of 5-fluorouracil (5-FU) (1,000 mg/m2/24 hours for 72 hours) and cisplatin (DDP) (50 mg/m2) for a total of three cycles. Thirteen patients had Stage IV disease; three, Stage III disease; and one, Stage II hypopharyngeal disease. Thirteen of 17 patients had positive cervical lymph nodes, and the mean size of the largest lymph node was 5.5 x 5.1 cm. The patients were not treated with planned adjunctive surgery except for one patient who had a radical neck dissection for massive, rapidly growing cervical adenopathy, which recurred promptly within 1 month before the initiation of protocol therapy. After the initial six patients were entered, mitomycin-C (Mito 8 mg/m2) was added during the second cycle. All the patients completed the planned course of radiotherapy with a median dose of 7,440 cGy and a mean dose of 7,248 cGy except for two patients who died--one from toxicity and the other, suicide. The predominant toxicity was mucositis, which was grade 3/4 in 11 of 15 patients, resulting in an average interruption of radiation therapy of 12 days. Weight loss was significant and was on the average 12% of baseline weight. Hematological toxicity was mild in the 5-FU/DDP group (only one grade 3 toxicity of six) and severe in the 5-FU/DDP/Mito-treated patients (five of eight patients having grade 3/4 toxicity including one leukopenic pneumonitis death). Additional toxicity included one parapharyngeal cellulitis, which responded to antibiotics. Noncompliance with the complex regimen was only seen in three patients. One patient refused b.i.d. radiation therapy, and one patient refused further chemotherapy after the first cycle. Additionally, one patient who had a severe ethanol withdrawal reaction during the first cycle of 5-FU/DDP did not receive further chemotherapy. The complete response rate of both primary site and neck by the protocol regimen alone was 71%. However, two patients, one from each group, did undergo salvage neck dissection, and the locoregional control is currently 73%, with a mean follow-up time of 18.4 months. The feasibility of combining hyperfractionated radiation therapy with aggressive concurrent chemotherapy was demonstrated. The response and local control rate justifies the added toxicity of concurrent chemotherapy and radiation therapy.

RESUMEN

The osteoplastic flap technique for exposure of the frontal sinus has been an accepted approach for cases in which obliteration or exploration of the frontal sinus has been necessary. Preservation of vascularized anterior pericranium is credited with reduction of the chances of anterior table bone resorption and subsequent cosmetic deformity. Disadvantages include the need for templates and unpredictable random fracturing in the supraorbital rim area, increasing the chance of potential injury to the periorbita and/or supraorbital neurovascular structures as well as limiting surgical exposure in some cases. Ten patients with chronic frontal sinusitis underwent frontal sinus obliteration using an anterior table free bone graft technique over a 3 year period. The superior orbital neurovascular pedicles were easily identified and protected within its pericranial sheath in all cases. All patients had precise delineation of the frontal sinus anterior bone flap margins with no need for templates. Bone graft viability was documented in all patients, along with excellent cosmetic results comparable to the osteoplastic flap technique. A review of the literature and description of the technique are presented.

RESUMEN

Seven patients underwent cold-steel uvulopalatoplasty with tissue removal similar to that being performed with laser-assisted uvulopalatoplasty. The severity and length of postoperative pain, days out of work, postoperative complications, and efficacy in reducing snoring were assessed. The minimum follow-up period was 6 months. The average length of postoperative pain (inability to eat a completely normal diet) was 6 days. All but one patient underwent only one session of cold-steel uvulopalatoplasty with satisfactory relief of snoring. The remaining patient required two sessions. One patient had some mild postoperative bleeding, which resolved with silver nitrate. Improvement in snoring goes as follows: marked improvement in three patients, moderate improvement in three patients, and slight improvement in one patient. None of the patients had complete resolution or the same degree of snoring. Patients who underwent concomitant oropharyngeal procedures (i.e., tonsillectomy) in addition to cold-steel uvulopalatoplasty tended to have pain for a longer period of time and required a longer convalescence period. Cold-steel uvulopalatoplasty is an inexpensive and viable option to outpatient laser-assisted uvulopalatoplasty for the reduction of snoring in select patients.

RESUMEN

OBJECTIVES: To determine the necessity for lumbar drains during endoscopic cerebrospinal fluid (CSF) rhinorrhea repair. METHODS: Thirty-three patients underwent endoscopic repair of CSF rhinorrhea without a lumbar drain during a 7-year period. The size of the dural defect ranged from a microleak (less than 1 mm dural defect) to a 3-cm dural defect of the anterior skull base. RESULTS: All of the procedures in patients with smaller defects (<5 mm) were performed on an outpatient basis. Thirty-two patients (97%) had complete resolution of their CSF leak after 1 procedure without any recurrence (average follow-up 29 months). CONCLUSION: A lumbar drain is not routinely necessary for successful closure of CSF rhinorrhea of any size. Smaller dural defects may be safely performed on an outpatient basis without complications.

RESUMEN

While videostrobolaryngoscopy is not a new technique, its acceptance as a routine part of the voice evaluation has not been as forthcoming. Many are in agreement that the rigid fiberoptic telescopes in combination with standard VHS equipment provide a clear, magnified image that can be recorded and used for pretreatment and post-treatment comparisons, documentation, teaching, and research. Yet, some skepticism persists with regard to the ability of videolaryngoscopy and/or videostrobolaryngoscopy in changing the diagnosis and treatment outcome of patients with voice disorders as compared to indirect laryngoscopy. Two hundred ninety-two dysphonic patients were identified who underwent indirect as well as videolaryngoscopy with and without stroboscopic examination. Videostrobolaryngoscopy was found to alter the diagnosis and treatment outcome in 14% of the patients. It is most useful in patients with a diagnosis of functional dysphonia and vocal fold paralysis by indirect laryngoscopy. The increased illumination and magnification afforded by rigid fiberoptic telescopes during videolaryngoscopy, combined with the detailed assessment of glottic closure, mucosal wave, and amplitude characteristics provided by stroboscopic examination, allowed detection of subtle vocal fold pathology, otherwise missed by indirect laryngoscopy.

RESUMEN

BACKGROUND: A new technique for permanent sectioning of the human spinal cord has provided superior images over those produced with traditional methods. Application of this technique for sections of the human larynx may yield cost-effective, efficient, and accurate laryngeal anatomic dissections. STUDY DESIGN AND METHODS: This study was designed to evaluate this technique for dissections of the human larynx. Laryngeal sections from cadavers were submerged in a celloidin solution, a derivative of wallpaper plaster, and frozen to -15 degrees C. After preparation, axial and coronal cuts of 100 microm were made with a Macrocut Tome sectioning system. RESULTS: Sections were completed in approximately 30 hours. Digitized photographs of the laryngeal sections provide detailed images of precise anatomic relationships. CONCLUSION: Celloidin-based sectioning of the human larynx yields precise anatomic information beyond standard radiographic imagining and previous permanent laryngeal sectioning techniques in a cost-efficient and timely manner. Black and white fine-section photographs are provided.

RESUMEN

Fifty-three patients underwent laser cordectomy for T1 glottic squamous cell carcinoma between January 1980 and December 1989--sixteen after having undergone unsuccessful radiation and thirty-seven who had no previous treatment. There was a 51% five-year cure rate in the irradiated group vs. 62% in the nonirradiated group. Extension of tumor to the anterior commissure resulted in a higher failure rate. Patients experienced an overall 5-year cure rate of 98% after surgical or radiation salvage of unsuccessful laser cordectomies. Six patients had preoperative and postoperative videostrobolaryngoscopy. The most common postoperative problem with voice was a breathiness that did not resolve in any of the patients. All patients had absent or moderately reduced amplitude and mucosal wave patterns and imcomplete glottic closure proportional to the amount of cordal tissue removed. Despite it seemingly poor results in carefully selected patients, laser cordectomy is still indicated without compromising the ultimate oncologic results. Advantages over radiation therapy or conservation laryngeal surgery include a short treatment time, requiring only an outpatient surgical procedure at the time of the initial diagnostic and/or staging laryngoscopy, and the avoidance of potential radiation side effects or surgical complications. However, patients should be advised the possibility of persistent postoperative breathy dysphonia, in addition to the possibility of further treatment to effect a long-term cure.

RESUMEN

OBJECTIVE: After thyroplasty type I, significant improvement has been reported in objective measures of vocal function. The purpose of this investigation was to compare the short- and long-term results in patients undergoing thyroplasty type I. METHODS: Data on 26 patients who had undergone thyroplasty type I for management of unilateral vocal fold paralysis were compared from before surgery to the short-term (1-month) and long-term (>1-year) postoperative assessment points. Statistical analysis included paired tests to assess the significance of between-group differences. RESULTS: Significant differences were found between the preoperative and both postoperative evaluations for the measures of mean glottal flow rate, maximum phonation time, jitter, shimmer, and harmonic-to-noise ratio. However, no significant differences were found between the 1-month and >1-year assessment points. CONCLUSIONS: The results for the parameters studied appeared to reach maximum improvement within 1 month after surgery. It is possible that the effects of time, including the normal aging process, hormonal changes, or other alterations in general health, may require longer follow-up to better address these issues.

RESUMEN

OBJECTIVE: Abnormalities in the mucosal lining of the vocal folds may interfere with the normal vibratory patterns and result in vocal limitations, especially for singers whose demands are great. A prospective, longitudinal study was undertaken to investigate the incidence of laryngeal abnormalities in asymptomatic singing students. METHODS: Sixty-five singing students at the school of music underwent videostroboscopic evaluation and completed a comprehensive questionnaire. Videos were rated by 3 experienced clinicians, and interrater reliability was calculated. Results were correlated with demographic factors, background medical history, and singing history. RESULTS: Five students (8.3%) exhibited early signs of benign vocal fold lesions (2 with nodules and 3 with cysts). A high incidence of posterior erythema (n = 44; 73.4%), suggesting possible reflux, was found. CONCLUSIONS: A surprisingly high number of otherwise asymptomatic singing students demonstrated abnormal laryngeal findings. Their relationship with vocal performance will be addressed as well as implications for preventative measures.
