Objective. The objective of this study is to analyse surgical outcomes in a series of patients who underwent subtotal petrosectomy in combination with cochlear implantation. Methods. Retrospective chart review. Thirty patients (32 ears) underwent subtotal petrosectomy and cochlear implantation in one stage. Indications for subtotal petrosectomy included the following: cholesteatoma, chronic otitis media, previous canal wall-down, osteoradionecrosis, revision surgery for clinical reasons, inner ear malformations, middle ear anatomical variations and severe cochlear ossification. Results. Follow-up ranged from 2 to 54 months. Only 2 complications related to the subtotal petrosectomy (1 subcutaneous abdominal haematoma and 1 subcutaneous abdominal seroma) occurred in this series. Complete electrode insertion was achieved in all but 4 cases. Conclusions. Subtotal petrosectomy is a safe procedure and can offer technical advantages in some cases of complex cochlear implantation.
Background: Though osteomas can commonly arise in the cranial bones, an extra canalicular mastoid bone location is a rare entity with less than 200 cases described to date. We present three cases of cortical mastoid bone osteomas and compare them with cases presented in the literature. Methods: In this study, we used a retrospective chart analysis. Results: All three patients presented after years of progressively increasing postauricular swelling without symptoms. Temporal bone non-contrast CT allowed accurate preoperative diagnosis. Surgical treatment was performed for cosmetic issues with minimal postoperative morbidity. Complete excision was achieved in all cases, and to date, there is no evidence of recurrence. Conclusions: Mastoid osteomas are rare benign slow-growing tumors. They usually present as a painless cosmetic disfigurement and are otherwise asymptomatic. Surgical excision is the treatment of choice when they cause esthetic discomfort or are symptomatic. Recurrences are infrequently reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
