Lipoma removal is a routine surgical procedure, and in most cases, it can be safely performed under local anaesthetic. This means the area is numbed, but you’re awake throughout – allowing for a quick, same-day treatment with minimal recovery time. However, not all lipomas are the same. In more complex cases, especially those involving large or deep growths, general anaesthetic may be advised.
Understanding when anaesthetic is required – and which type is most appropriate – depends on several clinical factors. This guide explains how decisions are made, what to expect during the procedure, and when general anaesthetic might be recommended instead.
When Is Anaesthetic Required for Lipoma Removal?
All lipoma removals require some form of anaesthetic to ensure patient comfort and safety. The type used depends on:
| Factor | Local Anaesthetic | General Anaesthetic |
|---|---|---|
| Size of lipoma | Small to medium (usually <5 cm) | Large (>5–7 cm) or involving multiple sites |
| Depth | Superficial, just under the skin | Deep or within muscle tissue |
| Number of lipomas | One or two | Multiple lipomas in one session |
| Location | Easily accessible areas (arm, back) | Complex or sensitive areas (groin, neck) |
| Patient preference/anxiety | Calm, cooperative patients | Those with high anxiety or low pain tolerance |
| Medical complexity | Routine outpatient procedure | Complex dissection, longer duration |
In most cases, local anaesthetic is sufficient, and the procedure takes 30–60 minutes depending on the lipoma. The decision is made after a proper examination and review of the patient’s medical history.
How Lipomas Are Removed Under Local Anaesthetic
Step-by-Step Overview:
- Area is cleaned and numbed with an injection of local anaesthetic
- A small incision is made directly over the lipoma
- The lipoma is gently dissected and removed in one piece, including its capsule
- The wound is closed with dissolvable or non-dissolvable stitches, depending on size
- A dressing is applied, and aftercare instructions are given
Key Benefits of Local Anaesthetic:
- No fasting required before surgery
- Quick discharge – patients can go home the same day
- Lower risk profile compared to general anaesthetic
- Minimal downtime – most return to normal activities within 48–72 hours
- Well-tolerated – suitable for most healthy adults
Patients may feel slight pressure or movement during the procedure, but no pain.
When General Anaesthetic Might Be Recommended
Although uncommon, general anaesthetic may be necessary in specific situations. This involves being fully asleep for the procedure, with an anaesthetist present throughout.
Situations Where General Anaesthetic May Be Preferred:
- Large lipomas that require deeper or more complex dissection
- Multiple lipomas being removed in one session (e.g. genetic conditions like familial multiple lipomatosis)
- Lipomas located in sensitive or hard-to-access areas, such as:
- The groin
- The neck or jawline
- Deep within muscle or fascia
- Anxious patients who are unable to remain still or are distressed by minor surgery
- Patients with low pain threshold or previous negative experiences with local anaesthetic
General anaesthetic requires a hospital setting and may involve slightly longer recovery, but it’s still considered very safe for otherwise healthy individuals.
In most cases, lipoma removal is a minor outpatient procedure under local anaesthetic, with minimal disruption to daily life. However, a proper assessment ensures the safest and most comfortable option is chosen. At City Dermatology Clinic, all procedures are led by experienced doctors who will guide you through the right anaesthetic pathway for your specific case.
