Surgical anatomy of the orbit.

When operating in and around the orbit, the key to a successful operative result is precise, anatomic localization. This study was constructed to give pertinent anatomic measurements to which the maxillofacial surgeon may refer. The safe distances noted from this study are: 1) medially 30 mm from the anterior lacrimal crest; 2) inferiorly 25 mm from the infraorbital foramen; 3) superiorly 30 mm from the supraorbital notch; and 4) laterally 25 mm from the frontozygomatic suture.

Vocal cord dysfunction - an industrial health hazard.

Vocal cord dysfunction has a definite incidence of association with high environmental noise levels. Our study has shown roughly an 8% incidence of vocal cord dysfunction (vocal cord nodules, vocal cord polyps and chronic laryngitis) in individuals working in high noise environments. In addition, those individuals who have surgery for vocal cord nodules and who work in high noise environments will have over a 30% incidence of recurrent vocal cord dysfunction following surgery. Our study indicates that females tend to be more at risk in high noise environments than males.

Quantitative and objective evaluation of vocal cord function.

Objective and quantitative evaluation of vocal cord function is a goal that has been difficult for voice clinicians to obtain. To be useful as a clinical screening tool it must be easy to perform, it must produce numerical storable data, it must have a high degree of accuracy, and it must be cost-effective. The results of this study have shown that using the perturbation factor and the equipment described, a successful rate of greater than 93% can be obtained in evaluating vocal cord dysfunction. The results further indicate that this equipment can be used much in the same way as an audiogram to follow-up and clinically evaluate on an objective basis the function of the vocal cords.

Anesthetic management for tracheobronchial laser surgery.

The use of the laser has become a well-recognized means of treating obstructing lesions of the tracheobronchial tree. Patients with lower airway compromise are in a precarious state of equilibrium. Everything done by the endoscopy-anesthesiology team tends to change this balance. Cooperation and coordination of this well-disciplined team is needed for efficient treatment of difficult cases. This paper outlines our surgical techniques, which have been tempered and modified to an anesthetic technique that provides the greatest safety with comfort. We detail the basic anesthetic methods for drug usage, pulmonary ventilation, and patient monitoring that we now use. A careful analysis of our results is presented to show that this technique does provide relatively safe anesthesia in this difficult setting.

Bacteriologic findings from the nose, ethmoid, and bloodstream during endoscopic surgery for chronic rhinosinusitis: implications for antibiotic therapy.

This study addresses the bacterial flora of chronic rhinosinusitis at the time of endoscopic sinus surgery. We used the consensus definition of chronic rhinosinusitis as the presence of paranasal sinus inflammation present for greater than 12 weeks. In our patient study group, all cases of chronic rhinosinusitis had failed to respond to antibiotic therapy and had not been treated previously with surgery. By microscopic examination, chronic inflammatory changes were confirmed in the resected sinus lining of all study patients. Intraoperative cultures were obtained from the nasal vestibule, the middle meatus, ethmoid lining, and peripheral blood during and after the endoscopic procedure. We found approximately 30% of the patients with sterile sinuses, 50% with coagulase-negative staphylococci, and the remainder with a mixed group of "nonpathogenic" organisms. Anaerobes were conspicuously rare. The blood cultures were positive in 7% of cases and were consistent with an organism of the operative site. This is the first time bacteremia has been reported in association with endoscopic sinus surgery. The results suggest that chronic rhinosinusitis is not a bacterial disease, but rather the result of chronic inflammation produced by a previous acute inflammation. The incidence of positive blood cultures, while relatively low and cleared quickly, should alert the physician for the possible need for prophylactic antibiotics in patients with cardiac, prosthetic, or systemic conditions that could lead to metastatic infection.
