Have you ever known someone who spent a fortune on axillary osmidrosis surgery, endured the incision and recovery, only to have that familiar odour return within a year? They fall into anxiety – “Did the surgery fail?” – and even start doubting the surgeon’s skill.
Many assume that if the odour returns after surgery, it must be “relapse”, and they just have to accept it. But that’s not the case.
What many do is confuse 〖”incomplete removal”〗 with 〖”true recurrence”〗.
This article breaks it down directly: If the odour reappears after surgery, is it because of residual glands that weren’t cleared, or because the apocrine glands have actually regenerated? And – how should you choose a second surgery?
💡 Core insight: Odour recurrence within one year – 90% of cases are “incomplete removal”; recurrence after three years or more is closer to “true regeneration”.
Many patients panic the moment they detect any odour, thinking “it’s relapsed”. But from a dermatological surgery perspective, “incomplete removal” and “true recurrence” have completely different pathology, timelines, and corrective approaches. Look at this table and you’ll have a clearer picture.
| Dimension | ❌ Incomplete removal (residual) | 🔄 True recurrence (regrowth) |
|---|---|---|
| Definition | Apocrine glands not fully excised during surgery; residual glands continue secreting | Apocrine glands regenerate or compensatory hyperplasia after surgery, regaining secretory function |
| Clinical presentation | Odour gradually reappears 3–12 months post‑op; similar to pre‑op but less intense | Odour appears 3–5 years or more after surgery, from none to present, gradually intensifying |
| Root cause | Inadequate surgical field / limited technique (e.g., curettage, blind micro‑surgery) leading to retained glands | Regeneration of apocrine stem cells or new gland development after puberty (especially in younger patients) |
| Reversibility | ✅ Removable Second surgery can completely excise residual glands | ⚠️ Controllable but hard to cure Requires repeat surgery with meticulous handling of regenerated glands |
| Revision difficulty | Relatively low – second surgery precisely targets residual areas | Higher – needs full‑layer excision and measures to prevent tertiary recurrence; demands highly experienced surgeon |
〖 In summary: If odour recurs within one year, don’t blame yourself – it’s most likely “incomplete removal”; if it returns after five years, then consider “true recurrence”. 〗
Before deciding on a second surgery, do these things first to avoid going down the wrong path:
〖 Step 1: Check the timeline 〗 Recurrence ＜1 year post‑op → most likely residual; ＞3 years → evaluate regeneration possibility.
〖 Step 2: Get an iodine‑starch test 〗 Identify residual gland distribution – a “precise map” for the second surgery.
〖 Step 3: Choose flap excision 〗 The revision must use a direct‑vision technique to thoroughly clear residual or regenerated glands.
〖 Step 4: Regular follow‑up 〗 After the second surgery, have check‑ups every 6 months for 2 years to detect early signs of regrowth.
⚡ Core principle: Residual → targeted removal ｜ Regeneration → regional clearance – surgical strategy is entirely different.
| Dimension | 🧹 Incomplete removal (residual) | 🌱 True recurrence (regrowth) |
|---|---|---|
| Revision method | Secondary flap excision or targeted residual gland removal | Extended regional excision + intraoperative frozen section guidance to ensure no residual |
| Surgical extent | Remove only the residual area (mapped by iodine‑starch), less trauma | Must excise the entire axillary apocrine gland field, wider area |
| Recovery time | 2‑3 weeks recovery, lighter scarring | 4‑6 weeks recovery, more visible scarring |
| Cure rate | ＞95% – odour essentially eliminated after precise residual clearance | 80‑90% – very low regeneration possible; requires long‑term follow‑up |
| Technical difficulty | Moderate – requires experienced surgeon | Very high – requires senior axillary specialist to perform |
〖 In summary: Residual can be “spot‑treated”, regeneration needs “wide‑sweep” – your revision plan depends on which category you fall into. 〗
There is no clear line between “incomplete removal” and “true recurrence”,
but as long as you remember –
〖 If odour recurs within one year, check for residual first;if after three years, then consider regrowth. 〗
Early iodine‑starch testing → is the start of precise repair;
Blindly opting for a second surgery → is the beginning of endless cycles of trouble.
