Postoperative Complications After Extracapsular Dissection of Benign Parotid Lesions With Particular Reference to Facial Nerve Function

The authors report a retrospective analysis of data from 377 patients who underwent extracapsular dissection for benign parotid tumor. All procedures were performed employing a facial nerve monitor. In the immediate postoperative period 92 percent of facial nerves were normal. Temporary paresis was observed in 6 percent. A total of 8 patients (2 percent) developed permanent facial nerve paresis. The authors opine that this minimally invasive approach does not increase the recurrence rate and is as safe as standard parotidectomy with facial nerve dissection. See page 484

Tissue Regeneration of the Vocal Fold Using Bone Marrow Mesenchymal Stem Cells and Synthetic Extracellular Matrix Injections in Rats

The authors report experience in an animal model employing bone marrow mesenchymal stem cells implanted in a scarred vocal fold lamina propria. The most favorable outcomes were observed when the stem cells were placed within a synthetic extracellular matrix. The combined treatment had no observed cytotoxicity. See page 537

The Current Status of Audiologic Rehabilitation for Profound Unilateral Sensorineural Hearing Loss

This contemporary review discusses the efficacy of air conduction CROS hearing aids as well as bone anchored hearing aids (BAHA). Both provide limited patient satisfaction but do not truly restore sound localization. Challenges for future investigation in the rehabilitation of individuals with unilateral hearing loss are discussed. See page 552

Analysis of Hearing Preservation After Endolymphatic Mastoid Sac Surgery for Meniere's Disease

The authors retrospectively reviewed 58 patients with Meniere's Disease of whom 29 underwent endoscopic mastoid sac surgery after failed medical therapy while 29 were treated with medical therapy alone. The audiometric outcomes as measured by pure tone average or word recognition score were not statistically different. Surgical therapy to treat the vertigo of Meniere's Disease did not increase risk of hearing loss. See page 591

On the Cover

Illustration 1.

The cover features a new anatomical space localized in the retrotympanum called “subpyramidal space” (panel A). This new anatomical extent is beneath the pyramidal eminence and it is limited laterally by its medial aspect, medially by the lateral wall of the tympanum, inferiorly by the ponticulus, and posteriorly and superiorly by the Fallopian canal. The feature of this space is represented by its depth that could vary from a total absence (panel C) to a very deep space lying under the Fallopian canal (panel B) hiding a possible cholesteatoma.
