This independent library brings together research on aesthetic surgery, dental care, weight management, eye procedures, urology and hair restoration. Each summary separates findings from uncertainty and suggests questions for an authorised clinician.
Read summaries of published research, including findings, limitations and questions to discuss with a qualified clinician. Evidence from a study does not establish individual suitability. Covered in this category: FUE, DHI, beard and eyebrow restoration.
Studies of hair-graft hydration and storage range from laboratory culture to one randomised clinical trial. They raise useful questions about drying, timing and holding solutions, while leaving individual outcomes and a universal protocol unresolved.
Read the evidence summaryDonor density, follicular-unit composition and miniaturisation vary between people. Study averages and modelled extraction figures cannot establish an individual’s suitable graft supply or predict future hair loss.
Read the evidence summaryFUE removes follicular units from a limited donor area. Small studies link baseline hair density and shaft diameter with donor appearance, but they do not establish a universal safe graft count or guarantee how the area will look after surgery.
Read the evidence summaryStudies examine injection pain, comfort during the procedure and postoperative soreness separately. Here is what research on local anaesthetic devices, buffered solutions, tumescence and FUE or FUT pain can—and cannot—tell you.
Read the evidence summaryStudies compare different devices, punch edges and movements, with different outcomes. The evidence does not show that every powered FUE technique is better for every person.
Read the evidence summaryRead summaries of published research, including findings, limitations and questions to discuss with a qualified clinician. Evidence from a study does not establish individual suitability. Covered in this category: Primary and revision nose surgery.
Randomised trials and reviews suggest piezoelectric bone cutting may reduce some early bruising and swelling scores after rhinoplasty, but findings vary and cannot predict an individual recovery.
Read the evidence summaryThe UK NAIROS randomised trial compared septoplasty with six months of saline and steroid nasal sprays in adults with a deviated septum and at least moderate obstruction. It found a larger improvement in reported symptoms after surgery at six months, with a smaller difference still present at one year. The findings also need to be read alongside surgical complications, crossover between groups and the study’s limits.
Read the evidence summaryObjective studies show that nasal swelling usually falls over time, while measurable changes in volume and contour can continue for months. Here is what the evidence measures, and what it cannot predict for an individual.
Read the evidence summaryRhinoplasty studies report different rates for bleeding, haematoma and infection because they count different events and follow patients for different periods. Learn how to interpret the evidence and when to contact the surgical team.
Read the evidence summaryA retrospective rhinoplasty cohort found no statistically significant difference in selected outcomes between smoking groups, but cannot prove risks equal or smoking safe. Wider surgical evidence does not set an individual quit date.
Read the evidence summaryRead summaries of published research, including findings, limitations and questions to discuss with a qualified clinician. Evidence from a study does not establish individual suitability. Covered in this category: Augmentation, lifts, reduction and implant revision.
A randomised study of implant-based breast augmentation reported earlier arm elevation and differences in pain, daily activity and opioid use with an enhanced recovery pathway. A separate, uncontrolled cohort covered several aesthetic breast procedures. Neither study gives a dependable personal recovery timetable or a return-to-work date.
Read the evidence summaryRandomised trials of pain relief after implant breast augmentation report mixed findings. This review separates block techniques, study groups and follow-up periods, including one study with mixed procedures.
Read the evidence summaryImplant planning involves more than choosing a volume. Research on measurement systems, patient preferences and 3D simulation shows why dimensions can inform a consultation, while individual anatomy, uncertainty and long-term device decisions still matter.
Read the evidence summaryA capsule naturally forms around a breast implant, but excessive tightening can cause firmness, distortion or pain. Research links several possible risk factors, while findings on implant pocket and prevention vary by surface, study design and follow-up.
Read the evidence summaryPublished haematoma rates vary because studies count different procedures and outcomes. This review separates diagnosed haematoma from operative blood-loss estimates, drain volumes and return-to-theatre events.
Read the evidence summaryRead summaries of published research, including findings, limitations and questions to discuss with a qualified clinician. Evidence from a study does not establish individual suitability. Covered in this category: Facelifts, eyelids, brows, ears and facial contour.
A careful review of direct comparisons, pooled outcomes, complications and revision studies explains what can—and cannot—be concluded about deep-plane and SMAS facelift techniques.
Read the evidence summaryRandomised eyelid-surgery studies examine injection pain, bruising and early swelling. Their findings help explain what has been measured—and what they cannot predict about an individual’s recovery.
Read the evidence summaryRead summaries of published research, including findings, limitations and questions to discuss with a qualified clinician. Evidence from a study does not establish individual suitability. Covered in this category: Liposuction, abdominal surgery and body lifts.
Research comparing drains and progressive tension sutures suggests possible differences in seroma risk after abdominoplasty, but varied techniques, small trials and different detection methods limit certainty.
Read the evidence summaryA systematic review of eight studies found that a transversus abdominis plane (TAP) block was associated with a longer time before the first pain medicine was needed after abdominoplasty. The evidence is encouraging but limited: total opioid use was not significantly different, techniques varied, and larger trials are needed.
Read the evidence summaryVenous blood clots after abdominoplasty are uncommon but potentially serious. Research differs on procedure-related risk and preventive medicines, while long-distance travel adds a separate period of immobility. Here is what the evidence can—and cannot—tell you.
Read the evidence summaryResearch offers useful but incomplete comparisons of combined breast and abdominal surgery, abdominoplasty alone and staged body-contouring operations. The studies do not establish that a combined mommy makeover is safer or better than a planned staged pathway for an individual patient.
Read the evidence summaryEvidence from abdominoplasty cohorts, a procedure-specific meta-analysis and a recent nicotine-exposure cohort helps explain why smoking and other nicotine use matter when discussing wound healing.
Read the evidence summaryHigh-definition liposuction aims to make selected body contours more visible. Published studies describe complications and recovery in particular groups, but most are uncontrolled and report outcomes differently, so they cannot establish a safest technique or predict an individual result.
Read the evidence summaryRead summaries of published research, including findings, limitations and questions to discuss with a qualified clinician. Evidence from a study does not establish individual suitability. Covered in this category: Implants, veneers, crowns and restorative dentistry.
Randomised trials and systematic reviews compare four- and six-implant support, immediate loading, bone-level changes, complications and the questions to settle with a treating clinical team.
Read the evidence summaryClinical studies link veneer outcomes with the tooth surface used for bonding, but group results cannot predict an individual result. See what research says about enamel, survival, complications and repair, and what remains uncertain.
Read the evidence summaryRegular, personalised maintenance helps a dental team monitor the tissues around an implant. Learn how mucositis differs from peri-implantitis, what follow-up research can and cannot show, and what to ask at your review.
Read the evidence summaryRead summaries of published research, including findings, limitations and questions to discuss with a qualified clinician. Evidence from a study does not establish individual suitability. Covered in this category: Sleeve, bypass, gastric balloons and endoscopic options.
Randomised sleeve-gastrectomy trials suggest that enhanced recovery pathways can shorten hospital time and improve some early symptoms. The protocols differ, discharge readiness is not the same as actual discharge, and small trials cannot rule out uncommon complications. Here is how to interpret the evidence and what to ask your care team.
Read the evidence summaryA research-led guide to endoscopic Medsil and Stella balloons and the swallowable Allurion system, covering outcomes, safety, removal and follow-up.
Read the evidence summaryEndoscopic sleeve gastroplasty reshapes the stomach with internal sutures; it is not surgical sleeve gastrectomy or a gastric balloon. Learn how trials measured weight loss, what selection and recovery evidence can tell you, and which questions to ask a clinical team.
Read the evidence summarySleeve gastrectomy and gastric bypass can both affect nutrient intake and status, but through partly different pathways. Ten-year trial follow-up, UK primary-care records and professional guidance show why lifelong monitoring matters—and what the evidence cannot tell an individual patient.
Read the evidence summaryRead summaries of published research, including findings, limitations and questions to discuss with a qualified clinician. Evidence from a study does not establish individual suitability. Covered in this category: LASIK, PRK, SMILE and cataract procedures.
Randomised paired-eye studies find some early differences in corneal sensitivity and tear-film measures between SMILE and LASIK, while patient-reported dryness does not always differ. The evidence cannot identify the right procedure for an individual or guarantee freedom from dry eye.
Read the evidence summaryCorneal maps, thickness measures and risk models each answer different questions before refractive surgery. See what the evidence shows, where it is uncertain and what to ask at a consultation.
Read the evidence summaryCataract surgery replaces the cloudy natural lens with an artificial intraocular lens. This guide explains what recovery and follow-up involve, which symptoms need urgent assessment, and how monofocal and multifocal or trifocal lenses differ in their visual trade-offs.
Read the evidence summaryRead summaries of published research, including findings, limitations and questions to discuss with a qualified clinician. Evidence from a study does not establish individual suitability. Covered in this category: Circumcision, penile procedures and intimate surgery.
Adult circumcision recovery depends on the reason for surgery and the technique used. Learn how to interpret complication studies, distinguish healing from return to activity or sex, recognise warning signs and plan follow-up.
Read the evidence summaryRandomised trials suggest that hyaluronic acid (HA) filler can increase measured penile girth for a time in selected men seeking cosmetic augmentation. The evidence does not establish a lasting result, a gain in length, improved sexual function or a risk-free procedure. This review separates HA from polylactic acid (PLA), summarises trial and complication data, and explains what current guidance says to discuss before making a decision.
Read the evidence summaryPenile implant infection is uncommon in many contemporary series but can require further surgery. This evidence review explains biofilm, coatings, revision surgery, diabetes research and the limits of current prevention data.
