The emergent surgical airway: cricothyrotomy vs. tracheotomy.

The American Society of Anesthesiologists difficult airway algorithm identifies two acceptable emergency surgical airways in the 'cannot intubate, cannot ventilate' scenario: cricothyrotomy and tracheotomy. Little has been published regarding the emergency surgical airway practices at different institutions. The authors investigated whether the primary choice of emergency surgical airway at a major level I trauma centre was cricothyrotomy or tracheotomy. A retrospective chart review was conducted of emergency airways performed over 6 years using relevant current procedural terminology codes. The electronic medical records obtained were reviewed to ensure accurate coding and verify the emergent nature of the procedure. Over the study period, there were 4312 documented emergent airways. 3197 (74.1%) were field intubated by paramedics, 1081 (25.1%) were hospital intubated by anaesthesia, 34 (0.008%) required emergency surgical access of which 24 were tracheotomies and 10 cricothyrotomies. Despite the emphasis in resident training and Advanced Trauma Life Support, there was a paucity of cricothyrotomies during the study period. At the authors' institution, tracheotomy is preferentially used as the emergency surgical airway. A multicentre prospective study is recommended to evaluate current practice in emergency surgical airway and to include the emergency open tracheotomy in residency training and continuing education if needed.

Orbital tumors.

Neoplasms involving the orbit are divided into primary and secondary types. Primary orbital tumors are rare, include a wide variety of histopathologic types, are usually benign, and most often are managed surgically. Secondary orbital tumors are most often malignant, arise from the paranasal sinuses, and are managed with multiple modalities in a planned fashion. This article discusses primary and secondary orbital tumors, including their evaluation and management.

Resorbable fixation in facial plastic and head and neck reconstructive surgery: an initial report on polylactic acid implants.

OBJECTIVES: The purpose of this study was to evaluate and report our initial experience with a resorbable fixation system in facial cosmetic and head and neck reconstructive surgery. The specific goals were to determine in which settings the absorbable system could be used, to evaluate the outcome of its use, to detail complications that occurred, and to report our observations on advantages and disadvantages of the system compared with traditional methods of osteosynthesis and fixation. STUDY DESIGN: A retrospective review of the initial 30 consecutive patients at the University of California, San Diego Division of Head and Neck Surgery who received polylactic acid (PLA) implants. SETTING: Academic tertiary referral/level I trauma center. METHODS: Criteria for inclusion into the study were any patient over age 18 who underwent a procedure involving the use of a PLA implant between March 1999 and October 2000. In addition to the typical indications for metal plate or mesh implantation, PLA was used for "protected bone regeneration." Detailed records were kept of all patients in whom PLA implants were used, including the exact procedure and type of implant. All patients were operated by the authors. Operative reports, hospital charts, and office records were analyzed for any perioperative or postoperative complications. The attending surgeon noted advantages and disadvantages of the system. Patients have been followed from 2 to 18 months at the time of this report and are part of an ongoing long-term follow-up study. RESULTS: PLA implants were used in 35 procedures on 30 consecutive patients (multiple unilateral fracture repairs were counted as a single procedure). Uses included fixation of craniofacial fractures (zygomaticomaxillary, orbit floor, frontal bone [N = 9]; fixation of craniofacial osteotomy [N = 8]; protected bone regeneration [N = 3]; mandible, cranial bone donor site [N = 2]; bone grafting [N = 2]; craniectomy reconstruction [N = 2], and soft tissue suspension [endoscopic browlifting, N = 6, static facial suspension, N = 1]). There were 4 complications in this series: 2 partial flap losses, 1 in a patient who had had preoperative radiation and the other in a heavy smoker; 1 infected cranial bone flap in a patient who had had two prior surgeries and radiation; and 1 wound dehiscence over a plate that was improperly contoured. Advantages noted by the surgeons were ease of contouring the mesh or plates, including in situ reshaping, apparent decrease in operative time, low implant profile, minimal soft tissue reaction, and radiolucency of the system, allowing postoperative imaging without metallic artifact. CONCLUSIONS: We found the PLA system to be highly effective, and noted no absolute contraindications to its use compared with standard metal plating systems. The 11% incidence of complications in this series was acceptable and probably not the result of the PLA implant material, although further experience is needed to determine the role of PLA implants in radiated tissue. The primary advantages to PLA appear to be its ease of use, radiolucency, eventual resorption, and, possibly, improved precision of reduction. The use in protected bone regeneration may also be an advantage, but long-term follow-up of our population will be needed to determine this. Based on short-term outcome analysis of our initial experience with PLA implantation, it appears to be an efficacious and safe technology for applications in head and neck and facial plastic surgery.

The lateral transorbital canthopexy for correction and prevention of ectropion: report of a procedure, grading system, and outcome study.

BACKGROUND: There are numerous approaches to correcting laxity of the lateral canthal tendon, each with advantages and drawbacks. Critical evaluation of these techniques is not possible, however, as there is no grading system currently in use to describe this condition or to report outcomes, and prospective trials are lacking. OBJECTIVES: To report and assess a new procedure for repair of the lateral canthus (lateral transorbital canthopexy) and to describe the Ectropion Grading Scale (EGS), with a prospective outcome analysis of their use. DESIGN: Prospective outcome study of 15 consecutive patients (16 procedures). SETTING: Tertiary referral center in Zurich, Switzerland. PATIENTS: Consecutive sample of patients referred for treatment of ectropion of various causes. INTERVENTIONS: Preoperative and postoperative EGS grades were recorded, a preoperative and postoperative patient-based questionnaire was administered, and lateral transorbital canthopexy was performed. MAIN OUTCOME MEASURES: Outcome was determined by improvement in EGS grade and results of the patient-based symptom questionnaire. RESULTS: There were no surgical failures or complications in the study. An average of 83% reduction in patient-reported discomfort was achieved. Two patients with facial paralysis needed medial canthal repositioning. The EGS allowed clear recording of lower eyelid position before and after lateral transorbital canthopexy, and the procedure was uncomplicated to perform. CONCLUSIONS: Lateral transorbital canthopexy is an effective technique for the correction of lower eyelid laxity and appears to allow refined, durable adjustment of the lateral canthus. Self-reported patient satisfaction confirmed the high rate of success of the procedure in this study. The EGS permits critical evaluation and reporting of results and may assist in predicting which patients will need concomitant correction of the medial canthus. Arch Facial Plast Surg. 2000;2:9-15

Percutaneous tracheostomy: a comprehensive evaluation.

Percutaneous tracheostomy (PT) is an ancient procedure that has recently attracted increasing interest. While there are numerous publications in the literature, there remains confusion due to the large variety of techniques and instruments with which it has been performed and the wide disparity in clinical outcome. This study evaluates the international literature on over 1,500 cases, classifies the techniques that have been used, analyzes the safety of each method, and reports a prospective outcome and cost analysis of 130 cases undergoing what we determined to be the safest method. We found that PT performed with the correct instruments and technique under bronchoscopic surveillance has a lower incidence of complications than open tracheostomy (OT). Cost estimation demonstrated that PT may be significantly more expensive than bedside OT. While we recommend PT as a relatively safe and expedient method of tracheostomy for selected intubated patients in an intensive care unit, it does not offer an advantage for patients who must be taken to the operating room, and should not deprive house officers of necessary experience in OT in this setting.

A prospective randomized double-blind trial of fibrin glue for pain and bleeding after tonsillectomy.

OBJECTIVES: The notable morbidity of tonsillectomy includes considerable postoperative pain and a rate of postoperative bleeding that have remained largely uninfluenced by modern surgical techniques or medication. Fibrin glue is known to have a hemostatic effect in some settings, and there is research suggesting it may also reduce postoperative pain. The objectives of this study were to evaluate the effect of fibrin glue on pain and bleeding after tonsillectomy. STUDY DESIGN: A prospective randomized double-blind study was performed on 50 consecutive adult patients undergoing tonsillectomy for chronic tonsillitis. METHODS: After removal of both tonsils the tonsillar fossa randomly assigned to the treatment protocol was coated with fibrin glue. The other side was left unaltered. The patient was then monitored for postoperative bleeding and wound healing, and a patient-based pain assessment instrument was used to evaluate symptoms every 8 hours for 10 days after surgery. RESULTS: Detailed evaluation of the pain scores allowed the authors to create a pain profile for what the typical patient experiences over the first 10 postoperative days, as well as during the course of a single day. The pain remains relatively constant for the first 7 days and begins to decrease only on the eighth postoperative day. During a single day there is increased pain in the morning compared with noon and evening. However, no statistically significant difference was detected in postoperative pain, bleeding, or healing between the wounds treated with fibrin glue and controls. CONCLUSIONS: The patient-based pain evaluation data should aid the physician in preoperative outcome counselling and targeted prescription of pain medication. However, contrary to previous indications, the authors cannot substantiate a significant beneficial effect of fibrin glue in postoperative pain control. Furthermore, we did not find its action as a hemostatic agent clinically applicable in this setting, and thus find no indication for the routine use of fibrin glue in tonsillectomy.

An update on the surgical treatment of temporal bone paraganglioma.

In 1982, Fisch described his results for the surgical treatment of 74 paragangliomas of the temporal bone, 5 years after his description of the infratemporal fossa approaches (types A and B). This study reviews the subsequent experience of the Department of Otolaryngology-Head and Neck Surgery of the University of Zürich with more than 136 surgically treated cases of paraganglioma of the temporal bone and discusses our current therapy 20 years after the initial description. One hundred nineteen (90%) of the patients had advanced tumors (Fisch class C or C+D), and 81 (68%) had intracranial extension. Total tumor excision was possible in 109 (82%) patients. Subtotal excision was performed in 22 (17%) patients, 21 of whom had intradural tumor invasion. In these cases, the resection was limited not by actual tumor size but by the degree of intracranial intradural tumor extension. Partial tumor excision was undertaken in only 1 patient with a C4De2Di2 tumor. The success rate in preservation of function of the lower cranial nerves was encouraging. Of the 69 patients whose facial nerve status was followed post-operatively, 81% maintained Fisch grade 76 to 100% (House-Brackman grades I and II). Analysis of follow-up data ranging from 2 to 11 years demonstrated 98% disease-free survival when total tumor extirpation was possible. In the patients who underwent subtotal or partial surgical resection there has been no subsequent tumor growth detected by either clinical or neuroradiological evaluation. We have confirmed after more than 20 years of experience that the infratemporal fossa approaches are a safe, highly effective means of surgical management of paragangliomas of the temporal bone, allowing eradication or arrest of disease with minimal morbidity. Limited intradural surgical resection in cases of very extensive tumors can greatly benefit patients for whom complete excision is not an option.

Expression of Her-2/neu oncogene protein product and epidermal growth factor receptors in surgical specimens of human breast cancers.

Her-2/neu protein product was immunocytochemically analyzed in 139 breast cancers. Epidermal growth factor receptors were similarly analyzed in 74 breast cancers from the same patient pool. These results were also separated on the basis of estrogen receptor proteins and of combined aneuploidy with elevated S-phase from flow cytometry. Invasive breast cancer yielded a positive label for Her-2/neu protein (26%) and for epidermal growth factor receptor (25%), with no significant difference. Correlations with estrogen receptor labeling yielded differences significant inversely for both Her-2/neu protein (p less than 0.02) and epidermal growth factor receptor (p less than 0.01). Positive Her-2/neu protein labels correlated with a positive combination of aneuploidy and elevated S-phase (37%) and a negative combination of aneuploidy and elevated S-phase (21%), with a statistically nonsignificant difference. Positive epidermal growth factor receptor cases with aneuploidy and an elevated S-phase (75%) and without aneuploidy and elevated S-phase (42%) did differ with significance at p less than 0.05. There were eight cases positive for both Her-2/neu protein and epidermal growth factor receptor, four of six cases with negative estrogen receptor, four of six cases with negative estrogen receptor, six of six cases aneuploid, and five of six cases with an elevated S-phase. All eight cases had threatening disease--either stage III or stage IV, with one case of extensive ductal carcinoma in situ (comedo). Correlation of negative Her-2/neu protein with negative epidermal growth factor receptor was significant (p less than 0.05) in 74 cases. However, positive Her-2/neu protein did not correlate with positive epidermal growth factor receptor; there was a trend toward inverse correlation. We conclude that epidermal growth factor receptor labeling results show similarities to Her-2/neu protein results, but epidermal growth factor receptor tended to correlate with unfavorable ploidy and S-phase. Epidermal growth factor receptor labeling might be useful in breast cancers with macrocysts reported to show high epidermal growth factor activity.
