Complications of endoscopic sinus surgery: analysis of 2108 patients--incidence and prevention.

The incidence of complications of endoscopic sinus surgery (ESS) in a combined experience with 2108 total patients is compared to complications in 11 other series of patients (2583 total) who underwent ESS and 6 series of patients (2110 total) who underwent traditional endonasal sinus surgery. The incidence of major perioperative complications was 0.85%, with cerebrospinal fluid (CSF) leak being the most common. The most common minor complications of ESS were those related to orbital penetration and middle turbinate adhesions; minor complications occurred in 6.9% of the 2108 patients. There were no statistically significant differences in the overall incidences of major complications between this series and the other two groups. Recommendations are made for the prevention of complications during ESS.

Endoscopic sinus surgery: 4-year follow-up on the first 100 patients.

Endoscopic sinus surgery has been reported to be successful, but lack of a standardized classification system hampers comparison of results between studies, and long-term results of surgery have not been reported in a series of consecutive patients. The results of our first 100 endoscopic sinus surgery procedures, reported previously after an average 9-month follow-up, were reviewed with the application of a new classification scheme and in light of a longer (4-year) follow-up. Surgery was successful in all patients whose sinus symptoms resulted from anatomical variations or suppurative infection, but failed in some patients with hyperplastic disease or polyps. In addition, the presence of reactive airway disease or the acetylsalicylic acid (ASA) triad was a bad prognostic sign. The overall success of the procedure in relieving sinus symptoms decreased from 98% at early follow-up to 91% at 4-year follow-up. Sixty-six percent were successful after one procedure and 25% required more than one procedure to achieve success. The decline in success since our first report in 1990 was mostly attributable to late failure in patients with recurrent symptomatic polyposis. Because symptoms may not recur in these patients for up to 3 years, long-term results of surgery for this disorder are necessary. Symptoms of recurrent polyposis can be controlled medically or by revision surgery.

Hypoglossal-facial nerve interpositional-jump graft for facial reanimation without tongue atrophy.

The hemitongue paralysis that occurs as a result of a classic hypoglossal-facial nerve crossover procedure can result in profound functional deficits in speech, mastication, and swallowing. The procedure is not an option in patients with bilateral facial paralysis or those at risk for combined cranial nerve deficits. To address some of the drawbacks and limitations of this classic procedure, we developed the hypoglossal-facial nerve interpositional jump graft (12-7 jump graft) procedure. This procedure involves interposing a nerve graft between a partially severed but functionally intact twelfth cranial nerve and the degenerated seventh cranial nerve, and is often combined with other reanimation procedures. To date, we have performed 33 12-7 jump graft procedures in 30 patients (three were treated for bilateral facial paralysis); this report describes the procedure and its indications, and details the results of 23 procedures performed in 20 patients for whom 24-month follow-up data are available. Twelfth nerve deficits occurred in only three patients in this report. Recovery of facial function began between 3 and 24 months postoperatively. Facial tone and symmetry were achieved in every patient, no patient had significant mass movement, and 13 patients (two of whom were treated for bilateral facial paralysis) had excellent and three had superb restoration of facial movement. These results show the 12-7 jump graft to be a valuable adjunct for facial reanimation in selected patients.

Gadolinium-enhanced magnetic resonance imaging of the facial nerve in herpes zoster oticus and Bell's palsy: clinical implications.

Gadolinium-enhanced magnetic resonance imaging was used in the evaluation of the facial nerve in four patients with idiopathic facial paralysis and six with herpes zoster oticus (HZO). Enhancement of the facial nerve was seen in all patients with Bell's palsy, and 50 percent of patients with HZO. The most consistent area of enhancement in both disorders involved the premeatal and labyrinthine segments. Although the images showed changes consistent with the type of viral process that is known to occur in these disorders, we found no significant correlation between the intensity or pattern of facial nerve enhancement on the images, the severity or duration of the disease, or the patient's prognosis for recovery. Nevertheless, gadolinium-enhanced MRI does have a place in the evaluation and decisions for management of select cases of facial paralysis.

Managing segmental facial nerve injuries by surgical repair.

This report describes our experiences and evolving philosophy with regard to managing segmental facial nerve injuries. We present the results of 13 facial nerve repairs of traumatic injury to a segment of the facial nerve. All peripheral facial nerve branches contribute essential elements to normal mimetic facial movement; therefore, we recommend early, appropriate repair of the nerve segment. This recommendation is based on principles established for managing disruptions of the main trunk of the facial nerve. It offers the patient the chance for complete recovery of facial function.

Video telescopic sinus surgery technique for teaching.

Video-endoscopic sinus surgery is a team approach which has evolved from classic, endoscopic sinus surgery in treating over 500 patients. Unlike classic endoscopic sinus surgery which has the surgeon viewing and operating through the endoscope, this technique permits the surgeon to operate while viewing the T.V. monitor using two hands for instrumentation. This technique greatly facilitates hands-on teaching and learning, while simultaneously providing a reproducible method of documentation.

Grading facial nerve function: House-Brackmann versus Burres-Fisch methods.

Many systems for reporting results of facial function tests have been proposed, but after five International Facial Nerve Symposia, a perfect system for reporting has yet to be developed. In 1985 the American Academy of Otolaryngology-Head and Neck Surgery adopted the House-Brackmann (H-B) six-point subjective grading scale as a universal standard. This decision was based on the recommendation of the Facial Nerve Disorders Committee. The next year, 1986, Burres and Fisch proposed the Linear Measurement Index (B-F LMI) as an alternative, objective grading system. To determine the ability of each system to grade the facial function of patients with facial palsy, and the relative merits of each system, 41 patients with facial weakness and one normal patient were studied. The H-B grading system is easy to use and provides simple, concise criteria for each separate grade of facial function. The B-F LMI grading system is time-consuming and labor-intensive, and requires a complex calculation to derive a percentage value that represents facial function. The most important finding of this study was the high degree of correlation between the two systems, in spite of the fact that the H-B system is subjective and qualitative while the B-F LMI system is objective and quantitative. Until the perfect grading system is developed, the authors favor combining the H-B and B-F LMI systems as the best method available at the moment to evaluate facial function.
