This single case describes immediate definitive closure using sharp debridement with adjunct polyhexanide (PHMB), a full-thickness skin graft (FTSG), and a polyurethane (PU) compression foam bolster. Methods: A 10-year-old boy with a severe contaminated lower-lip defect underwent debridement and 0.04% PHMB irrigation. An upper-arm FTSG was inset and compressed with a suture-anchored PU dressing. Topical PHMB gel was used perioperatively and for seven days after bolster removal. Oral antibiotics were given for five days. The patient was discharged eight days after the injury with detailed wound care instructions. Results: Immediate definitive closure was achieved with complete graft survival and no infection, necrosis, unplanned early dressing changes, or reoperations. At 12 months, oral competence, speech, lip mobility, and contour were preserved. However, mild residual esthetic differences remained (dyschromia, shallow border indentation, vellus hairs on the graft). Conclusion: In this single descriptive case, primary closure of a lower-lip injury with the combined intervention was associated with an uncomplicated functional course and manageable esthetic trade-offs at 12 months. These observations are descriptive; comparative studies with standardized functional, esthetic, and psychosocial measures are needed.<\/jats:p>","DOI":"10.3390\/children12101308","type":"journal-article","created":{"date-parts":[[2025,9,29]],"date-time":"2025-09-29T08:00:32Z","timestamp":1759132832000},"page":"1308","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Management of Severe Pediatric Lower Lip Defect After Canine Bite with Polyhexamethylene Biguanide (PHMB), Full-Thickness Skin Graft (FTSG) and Compression Foam: A Case Report"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6705-3292","authenticated-orcid":false,"given":"Aba","family":"L\u0151rincz","sequence":"first","affiliation":[{"name":"Division of Pediatric Surgery, Traumatology, Urology and Pediatric Otolaryngology, Department of Pediatrics, Clinical Complex, University of P\u00e9cs, 7 J\u00f3zsef Attila Street, 7623 P\u00e9cs, Hungary"},{"name":"Department of Thermophysiology, Institute for Translational Medicine, Medical School, University of P\u00e9cs, 12 Szigeti Street, 7624 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5584-9410","authenticated-orcid":false,"given":"Hermann","family":"Nudelman","sequence":"additional","affiliation":[{"name":"Division of Pediatric Surgery, Traumatology, Urology and Pediatric Otolaryngology, Department of Pediatrics, Clinical Complex, University of P\u00e9cs, 7 J\u00f3zsef Attila Street, 7623 P\u00e9cs, Hungary"},{"name":"Department of Thermophysiology, Institute for Translational Medicine, Medical School, University of P\u00e9cs, 12 Szigeti Street, 7624 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7748-6729","authenticated-orcid":false,"given":"Anna Gabriella","family":"Lamberti","sequence":"additional","affiliation":[{"name":"Division of Pediatric Surgery, Traumatology, Urology and Pediatric Otolaryngology, Department of Pediatrics, Clinical Complex, University of P\u00e9cs, 7 J\u00f3zsef Attila Street, 7623 P\u00e9cs, Hungary"},{"name":"Department of Thermophysiology, Institute for Translational Medicine, Medical School, University of P\u00e9cs, 12 Szigeti Street, 7624 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Attila","family":"V\u00e1sty\u00e1n","sequence":"additional","affiliation":[{"name":"Division of Pediatric Surgery, Traumatology, Urology and Pediatric Otolaryngology, Department of Pediatrics, Clinical Complex, University of P\u00e9cs, 7 J\u00f3zsef Attila Street, 7623 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enik\u0151","family":"Moln\u00e1r","sequence":"additional","affiliation":[{"name":"Division of Pediatric Surgery, Traumatology, Urology and Pediatric Otolaryngology, Department of Pediatrics, Clinical Complex, University of P\u00e9cs, 7 J\u00f3zsef Attila Street, 7623 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G\u00e1bor","family":"Pavlovics","sequence":"additional","affiliation":[{"name":"Plastic and Burn Surgery Department, Surgical Clinic, Clinical Complex, University of P\u00e9cs, Ifj\u00fas\u00e1g Street 13, 7624 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3348-5385","authenticated-orcid":false,"given":"Gerg\u0151","family":"J\u00f3zsa","sequence":"additional","affiliation":[{"name":"Division of Pediatric Surgery, Traumatology, Urology and Pediatric Otolaryngology, Department of Pediatrics, Clinical Complex, University of P\u00e9cs, 7 J\u00f3zsef Attila Street, 7623 P\u00e9cs, Hungary"},{"name":"Department of Thermophysiology, Institute for Translational Medicine, Medical School, University of P\u00e9cs, 12 Szigeti Street, 7624 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1228","DOI":"10.1016\/j.jpedsurg.2019.06.025","article-title":"Hospitalizations for Pediatric Dog Bite Injuries in the United States","volume":"55","author":"McLoughlin","year":"2020","journal-title":"J.
