Purpose: Chronic otitis media surgery is the most common procedure in otology in developing countries. Subtotal and total tympanic membrane (TM) perforation with inadequate anterior remnant is associated with higher rate of graft failure. It was the goal of this study to test the anatomical and functional outcomes of a modified underlay myringoplasty technique.
Materials And Methods: In a prospective clinical study, 45 patients with subtotal or total TM perforation and inadequate anterior remnant underwent tympanoplasty (+/-mastoidectomy). The anterior tip of the temporalis fascia was secured in a mucosal pocket on the lateral wall of eustachian tube orifice. Data on graft take rate, preoperative and postoperative hearing status, and intraoperative findings were analyzed.
Results: We achieved the graft success rate of 91.1%, without lateralization, blunting, atelectasia, or epithelial pearls. Approximately 24% patients had air-bone gap within 25 dB before intervention, which increased to 71% postoperatively (P < .001).
Conclusion: We believe that this technique could be a convenient and suitable method for cases with subtotal or total TM perforation and inadequate anterior remnant.

Unlabelled: Uremic leontiasis ossia (ULO) is a rare manifestation of renal osteodystrophy in) patients with end-stage chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPTH). It occurs due to increased osteoclastic activity secondary to high plasmatic parathyroid hormone (PTH) levels. This leads to bone deformation with thickening and massive enlargement of the cranial vault, resulting in a leonine face appearance.

Methods: Patients who underwent laparoscopic or robotic sTG or PG at the Shizuoka Cancer Center in Shizuoka between January 2014 and December 2020 were enrolled in this retrospective study. Patient characteristics, surgical outcomes, endoscopic findings, and postoperative nutritional changes, including blood tests, body weight, psoas muscle, and subcutaneous and visceral adipose tissue, were measured and compared between the two groups.

Background And Objectives: This article aims to report results of our facial nerve preservation approach to treating vestibular schwannomas (VS) at a single institution by a single surgeon performing both microsurgery (MS) and stereotactic radiosurgery (SRS).
Methods: We retrospectively reviewed 751 patients at our institution between 1998 and 2023 by intervention received: retrosigmoid microsurgery (MS, Group 1, 217 patients), gamma knife stereotactic radiosurgery (SRS, Group 2, 462 patients), MS then SRS (Group 3, 72 patients), SRS then MS (Group 4, 10 patients), and SRS then SRS (Group 5, 5 patients). No patients had MS followed by MS.

Introduction: There are inconsistencies in how different endoscopic procedures to manage Bilateral Vocal Fold Immobility (BVFI) have been described in the literature. This limits our ability to compare functional outcomes. There is no unifying international terminology available that precisely describes the anatomical boundaries and extent of the different types of treatment.
