Purpose To review our clinical experience with percutaneous injection laryngoplasty at a single institution over a three-year period, and to specifically assess the rate of unintentional injection into the superficial lamina propria (SLP) and compare with results found in the literature. Materials and Methods Medical records were retrospectively reviewed to identify patients who underwent office-based injection laryngoplasty (OBIL) over a three-year period. Video documentation and the written notes of the procedures were reviewed to determine the rate of inadvertent placement of injectate into the SLP. A literature review was performed to identify other reports of this complication and contributing factors. Results 113 consecutive patients were identified who underwent OBIL in the study period. Of these, 100 patients had adequate records and follow-up available for this review. All patients underwent injection augmentation with bovine collagen using a percutaneous trans-membrane or trans-cartilaginous technique. 96 had improvement in their vocal quality and/or effort. Four patients, who were all women, had unintentional injection into the SLP with resultant no change in voice or worsened voice. All superficially placed injectates were managed conservatively. Conclusions Injection into the SLP is a well-recognized possible complication of OBIL. Our results suggest that this complication occurs more often in women than in men, perhaps due to differing laryngeal anatomy and size.

Objective To review our experience in a series of patients who underwent revision endoscopic pituitary surgery. Methods Retrospective chart review. Results A total of 27 patients were included in the study. Of the 21 patients who required nasoseptal flap reconstruction, a left-sided nasoseptal flap was successfully used in 13 patients. Gross total or near-total resection of tumor was achieved in 74.1%. Cavernous sinus invasion and presentation with residual disease were identified as factors limiting extent of resection (p = 0.002 and 0.009, respectively). A statistically significant difference (p = 0.027) was noted between mean largest tumor dimension in patients with gross total resection and those with near-total or subtotal resection. Complications occurred in 22% and included postoperative temporary diabetes insipidus (n = 2), postoperative hypotension (n = 2), new anterior pituitary insufficiency (n = 1), and right-sided abducens palsy (n = 1). Conclusions Revision endoscopic pituitary surgery is advantageous but technically challenging. Cavernous sinus invasion and presentation with residual disease were significant factors limiting extent of resection. Suprasellar extension was not a factor limiting extent of resection and may prove to be an advantage over microscopic speculum-based approaches. Because of the right-sided scarring from prior surgery, a left-sided nasoseptal flap is reliable and advantageous.

Objectives?To present a critical evaluation of our experience using an expanded endoscopic endonasal approach (EEEA) to clival lesions and evaluate, based on the location of residual tumor, what the anatomic limitations to the approach are. Design?A retrospective review of all endoscopic endonasal operations performed at our institution identified 19 patients with lesions involving the clivus. Extent of resection was determined by preoperative and postoperative tumor volumes. Results?Three patients underwent planned subtotal resections. Of the remaining patients, gross total resection was achieved in 8/16 (50%), >?95% in 5/16 (31%), and
