Recovery and risks after styloidectomy

Recovery from styloidectomy, the operation to shorten the styloid process, is usually quick. In a US series comparing approaches, patients stayed in hospital for an average of 0.7 days after robotic surgery through the mouth and 1.2 days after surgery through the neck1. Recovery times vary with the approach, the extent of the operation and the surgeon's routine, so the surgeon's own timeline is the best guide.

After the operation

After surgery through the mouth, the throat is sore for some days, much as after a tonsillectomy, and soft food is easier at first. After surgery through the neck, the wound is in the upper neck below the jaw, and swallowing is usually less affected. In a series of 84 patients treated through a small cut in the neck, all were satisfied with the appearance of the scar2.

Operations for jugular compression are larger, because they also remove part of the C1 vertebra and free the vein from the surrounding tissue. Recovery takes longer, and improvement in symptoms of raised intracranial pressure can take weeks to months.

How soon symptoms improve

Most published patients improve. In a series of 21 patients, the median pain score fell from 6 out of 10 before surgery to 0 afterward; 90% had less pain and 62% had none3.

Some symptoms clear more completely than others. The feeling of something stuck in the throat and pain on swallowing were the symptoms most likely to disappear entirely in the Bargiel series. Patients with longer styloids, and those who had waited longer between their first symptoms and surgery, had more symptoms and took longer to recover2. In the Hardin series, neck and jaw pain responded best and headache least3.

Side effects and complications

The most common side effects in a series of 21 patients were first bite syndrome (24%), a cramping pain in the cheek or jaw with the first bites of a meal, and numbness (19%). Both usually settled within three months3.

Other reported complications include:

• Temporary facial weakness. The facial nerve leaves the skull just behind the base of the styloid. Weakness occurred in 1.2% of patients after surgery through the neck in a systematic review of published series4.
• Infection. An operation through the mouth opens into the throat, which carries a risk of deep neck infection5. A series of 58 patients treated through the mouth reported no deep neck infections6.
• Bleeding and injury to the carotid artery or jugular vein, which lie close to the styloid tip. Serious vascular injury is rarely reported.
• Nerve problems after jugular decompression. In a 2026 series of 14 patients, one had temporary shoulder weakness from injury to the accessory nerve7. In a series of 10, one patient had temporary difficulty swallowing and facial drooping and another reported jaw numbness8.

Which approach is safer is not settled. A 2019 review found more complications after surgery through the neck in published case reports (16.3% against 4.3% through the mouth) but very few with either approach in larger series4. A 2024 meta-analysis found the highest complication rate with surgery through the mouth9. In a small series, three patients had complications after open surgery and none after robotic surgery through the mouth1.

When symptoms persist or come back

Symptoms persist after surgery in a minority of patients, and some return. Among published patients with vascular complications treated first with styloidectomy, 2.5% had a recurrence10. Possible explanations include:

• the symptoms had another cause, such as a jaw joint disorder or a nerve pain condition
• too little of the styloid process was removed, or a calcified segment of the stylohyoid ligament was left behind
• the other side is also affected
• jugular compression at C1 was not addressed, so head pressure and related symptoms continue

Persistent symptoms call for a fresh look at the diagnosis and new imaging before any further operation.

Questions to ask before surgery

• Which approach do you recommend for me, and why?
• How much of the styloid process, and of any calcified ligament, will you remove?
• Is the carotid artery or jugular vein involved, and will the operation address it?
• How many of these operations do you do, and what results and complications have you seen?
• How long will I stay in hospital, and when can I eat normally, work and exercise?
• Which of my symptoms do you expect to improve, and which might not?
