A patient's condition extended suddenly behind the stemo-cleido-mastoid muscle. On October 2nd, an incision was made over the mastoid and perforated with a gimlet. Pus followed through the periosteum and on withdrawal of the gimlet. Dr. Agnew saw the case a year later, noting swelling in the auditory canal, tenderness in the concha and mastoid region, and a small fistulous opening leading to a narrow sinus towards the tympanic cavity. Symptoms included pain in the temporal bone, apprehension of brain disease, slight memory loss, nervousness, and wakefulness. In February 1870, the patient had an alarming attack with general agony, paralysis of the right seventh nerve, and vomiting. Dr. Agnew trephined the mastoid through a sweeping cut using a half-inch instrument, finding dense bone but no pus or caries. The patient improved significantly post-operation and remained well three years later.
Miss S.C., age 19, came under observation in February 1872 with deafness and previous ear pain, slight hemorrhage, and discharge of pus. Treatment included electricity for six weeks, after which the hearing was much improved. On April 20th, she had an acute attack of periostitis involving mastoid cells despite treatments like leeches and incision. An abscess formed in the posterior wall of the canal, discharging pus. Polypoid growths appeared from the mouth of the abscess, resisting astringents and excisions. The patient experienced constant aching with sharp pains in the mastoid process radiating to different parts of the temporal region.
After six weeks without substantial improvement, trephining was decided upon. On June 1st, an incision two inches and a half long down to the bone parallel with the auricle was made. A quarter-inch trephine was inserted on a line with the superior border of the external meatus about half an inch from the attachment of the auricle. After penetrating to half an inch depth, firm bone was encountered. The plug of bone was extracted and surprisingly little pus escaped. The wound healed without discharge or discomfort after six weeks.
Four weeks later, sharp pain in the ear followed by a throbbing sensation occurred after exposure to damp air. Examination revealed inflammatory action on anterior and inferior walls of canal with purulo-gelatinous material emitting an offensive odor. Mild current of electricity relieved pain within ten minutes but returned during night. Warm water injections were substituted with similar results, and quinine, iron, iodine potassium were prescribed.
Cases of caries and necrosis are detailed, emphasizing the importance of careful diagnosis to avoid penetrating important parts like dura mater or cerebrum. The anatomical relations of the cavity of the tympanum necessitate serious consequences from caries of any part of its walls, including great impairment of hearing, meningitis, cerebral abscess, pyaemia, paralysis, or fatal hemorrhage.
<Callout type="warning" title="Risk of Brain Involvement">Caries in the temporal bone can lead to inflammation of the brain and venous circulation issues due to proximity to the dura mater and cerebrum.</Callout>
Dr. Orne Green reported a post-mortem examination where caries occurred with an intact drum-head, leading to pus collection in the brain over a carious spot communicating with the tympanic cavity.

Dr. O.D. Pomeroy reported a case where the whole temporal bone exfoliated except for lower part of external auditory canal and inner petrous portion, resulting in facial paralysis.
Key Takeaways
- Mastoid surgery can be necessary to prevent complications from chronic suppurative processes.
- Careful diagnosis and surgical technique are crucial to avoid damaging important structures like the brain or dura mater.
- Post-operative care is essential for successful recovery.
Practical Tips
- Use warm water injections and mild electrical currents to manage pain effectively after surgery.
- Maintain thorough cleanliness of the ear post-surgery to prevent further complications.
- Monitor patients closely for signs of brain involvement such as headaches, dizziness, or vision issues.
Warnings & Risks
- Improper diagnosis can lead to penetration of important structures like the dura mater and cerebrum.
- Failure to treat chronic suppurative processes promptly may result in severe complications including meningitis or cerebral abscess.
- Post-operative care must be meticulous to prevent infections and ensure proper healing.
Modern Application
While modern medicine has advanced significantly, understanding the historical context of mastoid surgery is crucial. Techniques such as careful diagnosis and surgical precision remain relevant today. However, advancements in imaging technology and antibiotics have greatly improved patient outcomes and reduced risks.
Frequently Asked Questions
Q: What are the primary symptoms indicating a need for mastoid surgery?
Symptoms include swelling of the auditory canal, tenderness in the concha and mastoid region, small fistulous openings leading to sinuses, constant aching with sharp pains radiating from the temporal bone.
Q: Why is careful diagnosis important before performing surgery on the ear?
Careful diagnosis is crucial because probes cannot be used freely due to delicate surroundings and risk of penetrating important parts like the dura mater or cerebrum, which can lead to serious complications such as meningitis or cerebral abscess.
Q: What are some post-operative care measures recommended after mastoid surgery?
Post-operative care includes maintaining thorough cleanliness of the ear, using warm water injections and mild electrical currents for pain management, and monitoring patients closely for signs of brain involvement such as headaches or dizziness.
