Audiological and Surgical Correlates of Myringoplasty Associated with Ethnography in the Bay of Plenty, New Zealand.

Introduction: This retrospective cohort study of myringoplasty performed at Tauranga Hospital, Bay of Plenty, New Zealand from 2010 to 2020 sought to identify predictive factors for successful myringoplasty with particular consideration given to the known high prevalence of middle ear conditions in New Zealand Māori.

Methods: Outcomes were surgical success (perforation closure at 1 month) and hearing improvement, which were correlated against demographic, pathological, and surgical variables.

Results: 174 patients underwent 221 procedures (139 in children under 18 years old), with 66.

Hearing Loss Asymmetry due to Chronic Occupational Noise Exposure.

Objective: To determine whether occupational noise exposure causes symmetrical or asymmetrical hearing loss.

Study Design: Retrospective Case Series.

Setting: Otorhinolaryngology Specialist Centre.

The accuracy of otomicroscopy for the diagnosis of paediatric middle ear effusions.

Objective: To determine the diagnostic accuracy of otomicroscopy performed by otolaryngology specialists for the diagnosis of paediatric middle ear effusions.

Methods: Prospective study of consecutive children receiving tympanostomy tubes between December 2004 and February 2005 within the Department of Otolaryngology-Head & Neck Surgery, Manukau Surgery Centre, Middlemore Hospital, New Zealand. Eighty-six children were included in the study.

Osteoblast-like cell cultures from human stapes.

Objective: In order to develop new middle ear prostheses for ossicular reconstruction it is important to study how the recipient middle ear tissues, especially the stapes footplate and superstructure, react to the implanted biomaterial. In this respect, animal studies and cell cultures using non-specific cells are of limited value.

Material And Methods: The morphology and growth pattern of cells cultured from human stapes were studied.
