Powered partial adenoidectomy.

OBJECTIVE: To confirm our clinical impression that the powered microdebrider is superior to curettes for performing partial adenoidectomy (removal of the superior one half to three fourths of the adenoid pad). DESIGN: Observational study of 100 children undergoing partial adenoidectomy with the powered microdebrider compared with 40 children undergoing conventional partial adenoidectomy with curettes. SETTING: Private and public tertiary care centers. PATIENTS: All patients younger than 20 years undergoing partial adenoidectomy at the respective institutions during the study period. INTERVENTIONS: Partial adenoidectomy as indicated for chronic otitis media, airway obstruction, or chronic or recurrent tonsillitis with either the powered microdebrider or curettes. MAIN OUTCOMES MEASURES: Operative time (with specific quantification of the time required for tissue removal and hemostasis), blood loss, complications, and subjective ease of use. RESULTS: Operative time was 59% shorter for the microdebrider group (mean, 3 minutes 22 seconds; range, 1 minute 6 seconds to 12 minutes 45 seconds) than for the conventional group (mean, 8 minutes 8 seconds; range, 1 minute 2 seconds to 22 minutes 0 seconds) (P<.001). Blood loss was comparable for both groups (powered group: mean, 2.0 mL/kg; range, 0.4 to 9.4 mL/kg; conventional group: mean, 2.0 mL/kg; range, 0.3 to 6.7 mL/kg; P=.34). There were no intraoperative or postoperative complications in either group. Surgeon satisfaction with the microdebrider was high. CONCLUSIONS: The powered microdebrider for partial adenoidectomy is quicker and is not associated with blood loss or complications above that of conventional partial adenoidectomy. The degree of control afforded by the microdebrider technique is of utmost value in preventing complications such as velopharyngeal insufficiency, and this is now our procedure of choice.

Power-assisted partial adenoidectomy.

OBJECTIVE: To describe partial adenoidectomy using a powered microdebrider and review the experience with the procedure. STUDY DESIGN: Prospective study and review. METHODS: To perform a power-assisted partial adenoidectomy, the surgeon directs the window in the microdebrider blade tip toward the tissue, which is drawn in by suction; the rotating blade then shaves the tissue. Studies have compared this adenoidectomy technique with curette procedures. RESULTS: In a comparative prospective study, we found that operating time and time required for hemostasis were significantly shorter (P =.001) with power-assisted partial adenoidectomy than with curettage. There was no significant difference between the two procedures in blood loss or complication rate. These results were similar to those of previous studies. Overall, we have performed more than 1000 power-assisted partial adenoidectomies. No long-term complications have occurred, blood loss remains low, and surgeons are satisfied with the technique because of its speed, improved visibility during resection, and precision. CONCLUSION: We and other authors have found power-assisted partial adenoidectomy to provide a faster, more precise operation than curette techniques, with benefits for both patient and surgeon.

Hemifacial microsomia.

Hemifacial microsomia is the second most common congenital facial anomaly, second only to cleft lip and palate. While its precise etiology is not yet known, it is likely caused by a disruption in the development of the first two branchial arches early in embryologic development. The resulting phenotype is one of varying degrees of unilateral hypoplasia of the mandible, ear deformity, and macrostomia. Early diagnosis of hemifacial microsomia is important not only to plan for surgical reconstruction of affected features, but also to lead the physician in further evaluation for associated abnormalities or disabilities. This article will introduce the reader to the most common variants seen in hemifacial microsomia, discuss the possible etiologies of the anomalies, and will highlight the importance of evaluating these patients early in life for such potentially disabling but correctable problems such as hearing loss, feeding disabilities, and neurological deformities.
