2024年9月3日 · The fistula, post-auricular flap and inferior incision site are infiltrated with 15mls of LignospanTM Special to reduce haemorrhage from the vasoconstrictor effect but also to provide short-term anaesthesia to the patient, as sternocleidomastoid flap elevation and transposition is particularly painful.

Postaural mastoid fistula is a condition where an abnormal connection forms between the mastoid bone and the external ear canal. Treatment options for postaural mastoid fistula may involve surgical intervention, such as fistula repair or mastoidectomy.

This paper illustrates a method of closing a large postauricular mastoid cutaneous fistula. The steps include excising the fistula, everting the mastoid epithelium toward the external auditory meatus, covering the undersurface of the everted skin edges with an anteriorly based periosteal flap, covering the flap with bone paté, placing a free ...

Fistula of the mastoid is commonly caused by underlying ear infections, trauma to the ear, or complications from ear surgeries. Infections can lead to the formation of abnormal passages in the mastoid bone, while trauma or surgeries can disrupt the normal anatomy of the ear, resulting in fistula formation.

2024年8月10日 · Mastoid fistula is an abnormal connection between the mastoid cavity and the post-auricular skin. Formation of fistulas are often a rare complication of chronic suppurative otitis media (CSOM), repeated surgical procedures such as radical mastoid surgeries or spontaneous exteriorisation of cholesteatoma through the mastoid cavity.

2023年7月27日 · Post aural fistula after canal wall down (CWD) mastoidectomy can be successfully treated by fistula tract excision and obliterating the mastoid cavity. The mastoid-cutaneous fistula after mastoid surgery requires regional flaps for repair and a vascularized flap to prevent the necrosis of avascular tissue because there is insufficient tissue ...

Mastoid fistula is a rare condition, its causes include chronic suppurative otitis media and repeated ear surgeries. Management is challenging, simple closure typically leads to recurrence due to surrounding necrotic skin edges. Several surgical techniques have been described. In this paper, we pres …

The cutaneous mastoid fistula is a very rare complication of chronic suppurative otitis media. The fistula tracts are typically difficult to manage because of the surrounding necrotic skin edges. We describe an unusual case of a postauricular cutaneous mastoid fistula and outline the surgical technique used for closure.

Postauricular cutaneous mastoid fistula is a rare case, which may be caused by a complication of CSOM, [4] cholesteatoma, [5] mastoidectomy, [6] or breakdown after postauricular closure with poor skin margins. It is commonly unilateral, but a bilateral fistula may also occur.

Postauricular cutaneous mastoid fistula (PCMF) is a very rare complication of chronic suppurative otitis media (CSOM). PCMF is connecting the mastoid cavity with postauricular skin and commonly unilateral.
