Sinonasal inverted papilloma involving the temporal bone via the eustachian tube: case report
1Department of Otolaryngology, Head and Neck Surgery, Colchester General Hospital, UK. zwl20cam@gmail.com
Objective:
This study reports a case of a sinonasal inverted papilloma with spread to the temporal bone via the eustachian tube and subsequent transformation to squamous cell carcinoma.
Method:
An 81-year-old woman presented with sinonasal inverted papilloma which subsequently spread to the ear. A literature review of inverted papilloma was carried out based on a Pubmed search of studies published between 1987 and 2011, using the key words 'sinonasal inverted papilloma', 'temporal bone inverted papilloma' and 'squamous cell carcinoma'.
Results And Conclusion:
Sinonasal and temporal bone inverted papillomas may sometimes be linked through direct spread via the eustachian tube. Inverted papillomas have the potential for malignant transformation; careful monitoring of both the nose and ear is therefore required for inverted papillomas found in the nasopharynx.
