Name of the Procedure:

Sinusotomy Frontal; External, Simple (Trephine Operation)

Summary

A sinusotomy frontal, also known as a trephine operation, is a surgical procedure to open and drain the frontal sinus cavities, which are located in the forehead area. It is performed externally using a small drill called a trephine.

Purpose

The procedure addresses chronic sinusitis or recurrent sinus infections affecting the frontal sinuses. The goal is to create a passage for drainage and enhance sinus ventilation, thereby reducing symptoms and preventing further infections.

Indications

• Chronic or recurrent frontal sinusitis
• Failure of medical therapy (e.g., antibiotics, nasal sprays)
• Presence of a sinus obstruction or polyp
• Persistent headache or facial pain linked to sinus blockage

Preparation

• Fasting for at least 6-8 hours before the procedure if general anesthesia is used.
• Possible adjustment or discontinuation of certain medications (e.g., blood thinners).
• Diagnostic tests such as CT scans to assess the sinus structure and pathology.
• Preoperative consultation to discuss the procedure, risks, and benefits.

Procedure Description

1. The patient is administered local or general anesthesia, depending on the case complexity and patient preference.
2. An incision is made in the skin directly over the frontal sinus area.
3. Using a trephine, a small hole is drilled into the frontal sinus wall to create an opening.
4. Any obstructive material, such as mucus or polyps, is removed, and the sinus cavity is irrigated.
5. The incision is then closed with sutures, and a dressing may be applied.

Duration

The procedure typically takes about 1-2 hours.

Setting

This procedure is often performed in a hospital's operating room or an outpatient surgical center.

Personnel

• Otolaryngologist (ENT surgeon)
• Nursing staff
• Anesthesiologist (if general anesthesia is used)
• Surgical assistant (if needed)

Risks and Complications

• Infection
• Bleeding
• Swelling or bruising
• Scarring at the incision site
• Potential injury to surrounding structures, such as the eye or cranial cavity

Benefits

• Relief from chronic sinusitis symptoms
• Improved sinus drainage and ventilation
• Reduced frequency of sinus infections
• Significant symptom improvement within weeks following the procedure

Recovery

• Pain management with prescribed medications.
• Application of cold compresses to reduce swelling.
• Instructions to avoid strenuous activities for a few weeks.
• Follow-up appointments to monitor healing and sinus function.
• Most patients can return to normal activities within 1-2 weeks.

Alternatives

• Medical therapy (ongoing use of antibiotics, nasal sprays, or steroids)
• Balloon sinuplasty (a less invasive technique with a balloon device)
• Endoscopic sinus surgery (a minimally invasive internal approach)
• Each alternative has its pros and cons, including varying degrees of invasiveness, recovery time, and effectiveness.

Patient Experience

During the procedure, the patient might be under sedation or general anesthesia, so they will not feel any pain. Post-procedure, there may be discomfort at the incision site, managed with pain relief measures. Patients commonly experience relief from sinus symptoms within weeks, with full recovery expected in 1-2 weeks.
