The place of 'salvage' petrosectomy

Area of Science:

• Otolaryngology
• Oncology
• Radiation Oncology

Background:

• Carcinoma of the external auditory meatus and middle ear is a rare malignancy.
• Treatment options are limited and often involve radical surgery or radiotherapy.

Purpose of the Study:

• To evaluate the outcomes of radiotherapy in patients with carcinoma of the external auditory meatus and middle ear.
• To assess the role of salvage petrosectomy in recurrent cases.

Main Methods:

• Retrospective analysis of 58 patients with carcinoma of the external auditory meatus and middle ear.
• Thirty-three patients were treated with radiotherapy.
• Petrosectomy was considered for salvage in recurrent disease.

Main Results:

• Nineteen out of 58 patients experienced recurrence after radiotherapy.
• Petrosectomy was not suitable for any patients with middle ear tumors.
• A few patients with external auditory meatus tumors, particularly non-squamous types, survived after salvage petrosectomy.

Conclusions:

• Radiotherapy alone has a significant recurrence rate for these tumors.
• Petrosectomy is generally unsuitable for middle ear carcinoma.
• Salvage petrosectomy may offer a survival benefit for select cases of external auditory meatus carcinoma.
