Minimal access and standard cochlear implantation: a comparative study.

OBJECTIVE: To compare the operative times and complications between patients who underwent minimal access cochlear implantation and standard technique cochlear implantation. METHODS: Patients who underwent unilateral cochlear implantation by a single surgeon from 2001 to 2010. The minimal access technique of an approximately 2.5-3 cm post-auricular incision with creation of subperiosteal pocket for the device was compared to the longer standard "S" incision into the scalp (~8-10 cm) with bone well creation and suture fixation. Outcomes include operative times and complications. RESULTS: There were 122 unilateral implants, 73 (59.8%) in the minimal access group and 49 (40.2%) in the standard group. Mean total time in the operating room was lower in the minimal access group compared to the standard group (200±31 vs. 255±49 min, p<.0001) as well as mean operative time (149.5±28 vs. 200±45 min, p<.0001 respectively). There were 17 complications in the entire cohort with 8 and 9 complications in the minimal and standard groups respectively. Of the 17 complications, 12 were surgical technique-specific. Although it appeared that there were higher rates of major, technique-specific, and overall complications in the standard access group, these differences did not reach statistical significance. CONCLUSIONS: Patients undergoing minimal access cochlear implantation require shorter operative times when compared to the standard access cochlear implantation. In addition, low complication rates are observed for major, technique-specific, and overall complications. Minimal access cochlear implantation may be considered an equivalent and potentially superior technique.

Safety and feasibility of elective minimally invasive video-assisted central neck dissection for thyroid carcinoma.

BACKGROUND: Minimally invasive video-assisted thyroidectomy (MIVAT) is accepted as treatment for select patients with thyroid carcinoma. We report both benefits and limitations of elective central neck dissection performed with the MIVAT technique. METHODS: Patients undergoing elective central neck dissection with MIVAT during November 2006 to October 2009 were studied retrospectively. Outcomes included complications and recurrence rates. RESULTS: In all, 28 patients were studied. There were no recurrences, with median follow-up of 14 months. Eleven patients (39%) had positive central lymph nodes for metastases. No permanent hypocalcemia resulted, although 3 patients (10.7%) experienced transient hypocalcemia on postoperative day 1 (Ca <8 mg/dL). No permanent hypoparathyroidism resulted, although 7 patients (25%) had transient hypoparathyroidism (postanesthesia care unit parathyroid hormone [PTH] <8 mg/dL) treated with short-term supplementation. Transient recurrent laryngeal nerve paresis occurred in 1 patient (3.6%). At the most recent check, 91% of patients had low/undetectable (<1 ng/mL) thyroglobulin. CONCLUSIONS: Elective central neck dissection performed with MIVAT is a safe and feasible procedure in our institutional experience.

Comprehensive airway management of neonatal head and neck teratomas.

OBJECTIVES: To determine the success of initial airway management and to characterize late airway-related complications in patients with airway obstruction due to congenital head and neck teratomas. STUDY DESIGN: Case series with chart review. SETTING: Tertiary airway referral institution. SUBJECTS AND METHODS: Review of consecutive patients with congenital head and neck teratomas from 1988 to 2010. Variables examined include initial airway stabilization at time of birth and perinatal airway management. Outcomes include short- and long-term complications. RESULTS: Fourteen cases were reviewed. In 12 patients, initial airway management was accomplished on placental support with either intubation or tracheotomy. Two vaginal births required subsequent uncomplicated oral intubation within 24 hours. Nine patients required tracheotomy (3 within the delivery suite, 2 during mass excision on day of life 6 and 24, and the remaining 4 occurred at days 29, 32, 92, and 100). Five deaths occurred, 4 within several days of birth due to complications related to the cervical teratomas and 1 on day of life 32 due to an airway-related complication. Follow-up for surviving patients ranged from 1 month to 18 years. Long-term airway complications ranged from vocal cord paralysis to stenosis requiring laryngotracheoplasty. CONCLUSION: This study demonstrates that a multidisciplinary team and a standardized approach in the operating suite have led to successful initial airway stabilization. Furthermore, this study demonstrates the need for continued airway management after delivery. Reassessment of the airway after delivery and an airway management planning meeting with the multidisciplinary team may help decrease morbidity and mortality.

Intranasal Z-plasty for internal nasal valve collapse.

OBJECTIVE: To describe the technique of intranasal Z-plasty and early results for this minimally invasive method to repair internal nasal valve collapse. Intranasal Z-plasty has been well described for nasal valve stenosis and cleft nasal deformities but poorly described for idiopathic nasal valve collapse, the most common indication for nasal valve surgery. DESIGN: A retrospective medical record review was performed for 12 patients undergoing intranasal Z-plasty for nasal valve collapse. Medical records were evaluated for age, sex, indication for surgery, prior surgical procedures, complications, results, and length of follow-up. A visual analog scale was used to rate nasal obstruction preoperatively and postoperatively. RESULTS: A total of 8 men and 4 women underwent surgery, and the procedure was bilateral in 10 of the 12 patients, for a total of 22 nasal valves. Eleven patients noted subjective improvement in airflow on both sides, with the remaining patient noting improvement on one side and no change in the opposite side. Mean follow-up was 16.8 months (range, 5-32 months). The mean preoperative nasal obstruction score was 7.2, and the mean postoperative nasal obstruction score was 3.3 (on a scale of 0 to 10, with 10 being total obstruction). No complications were reported, and no patients complained about postoperative nasal appearance. CONCLUSION: Intranasal Z-plasty appears to be a safe, effective, and relatively noninvasive technique to repair internal nasal valve collapse.
