Slide Content
Reconstruction of head and neck defects –options and challenges Naveen hedne Chandrasekhar Ms , MCh Senior consultant and lead head and neck surgery Apollo cancer center chennai
Limitations –reconstructive surgeon
Break up History Application of reconstruction----oncological /non oncological Reconstruction options Available options Planning -Choosing the options Problems and challenges Way ahead
History The first pedicled flap-- Susruta in 800 BC -- forehead flap McGregor in 1963 popularized -turning point in reconstructive surgery---first ever reliable transposition flap 1979-Ariyan –pectoralis major myocutaneous flap ---- pectoral branch –thoraco acromial artery --- work horse Microvascular surgery - 1970s Daniel and Taylor-first cutaneous free flap in 1973 Free flap - reconstruction = gained popularity = standard of care for large head & neck defects
Need for reconstruction Ablative oncological surgery Benign tumors Traumatic defects Corrosive strictures Infections – co vid pandemic –fungal infections/ necrotizing fasciitis Non vital organ transplants -larynx, face, parathyroid
principles Provide lining Restore bone continuity Continuity of alimentary tract Prevent salivary leak Cover major blood vessels cosmesis
Sites Oral cavity Paranasal sinuses /orbit, and anterior skull base Laryngopharynx Trachea Scalp/ facial/Cutaneous defects Ear and lateral skull base Maxillo facial prosthetic and dental rehabilitation
Reconstruction ladder to ELEVATOR Reconstructive ladder – reconstruction elevator Primary closure - skin grafting -- local flaps regional/ free flaps
Principles Upper aero digestive tract ,head and neck - complex anatomy--critical structure--special senses Reconstruction involves restoration of both form and function Requires replacement of composite tissue like skin, bone and mucosa Reconstruction must aim at early healing for commencement of adjuvant therapy Minimize donor site morbidity Replace Like with like
Principles What is excisable is re constructible Replace like with like Patient consideration- age , comorbidities , prior treatment Defect and disease considerations Donor site Availability of recipient vessels Resource and surgeon consideration
algorithm
Free flaps vs regional flaps/local flaps Free flaps –versatility, robustness expertise / longer operative time Flap selection –complex-pros /cons
Options available Primary closure Skin graft- Split thickness skin graft/ full thickness skin graft Local flaps Regional flaps Free flaps-micro vascular tissue transfer Osseo integrated implant –prosthetic rehabilitation Tissue culture Non vital organ transplant
Classification of flaps Vascularity--- random /pedicled Composition--- cutaneous /myocutaneous/ osteo cutaneous Type of transfer-rotation / transposition / advancement / inter polated, free tissue transfer
Local flaps Flap harvested from adjacent area Reliable –extensive vascularity in head and neck Safe and predictable Simple and easy to harvest by primary surgeon Lesser operative time Tissue match- color and texture
Problems Limited availability – size –smaller Defects Oncological safety Neck status and surgery Facial scar
Local flaps in head and neck Rhomboid flap Bilobed flap Buccal fat pad Fore head flap Paramedian fore head flap Naso labial –islanded vs conventional FAMMF Buccal fat pad Palatal rotation Submental flap Platysmal flap INRAHYOID FLAP
Buccal fat pad
BCC excision and V Y Advancement flap
Famm flap
FAMM flap
Famm flap Mucosal lining Limited tissue IFAMM
Islanded Nasolabial flap for tongue reconstruction Good pliable tissue Reliable Can be tunneled under mandible Ontologically safe Easy to harvest Donor site –minimal morbidity FACIAL SCAR
OSMF Release + Bilateral islanded nasolabial flap
Islanded Nasolabial flap for lip reconstruction
post co vid fungal defect
Good pliable skin Limited amount of tissue Reach Good for pharyngeal defects Unreliable if prior neck dissection
Submental flap Oncological concerns Male –beard Reliable
Submental flap
Pre-op Post-op
Left extended maxillectomy + Reconstruction with prolene mesh + Temporalis flap + submental flap + Zygomatic basal implants + selective neck dissection ( I, II) + PEG tube insertion Post excision defect Dental impression for prosthesis
Infrahyoid flap
Infrahyoid flap + nasolabial flap Limited tissue Reach Bad scar
Temporalis flap
Forehead flap
Paramedian forehead + temporoparietal flap
Regional flaps Harvested from area near the defect site – islanded - intact blood supply- rotated into defect Good amount of skin and soft tissue Reasonably -reliable Reach is limited Lack of bone 1Pectoralis major myocutaneous flap 2Latissimus dorsi flap 3Trapezius flap 4Deltopectoral flap
PMMC Work horse in head and reconstruction Paradigm shift in H & N oncological surgery Reliable Easy to harvest Limitation- limited reach , bulky in women, Distortion of breast
pmmc
Follicular ca thyroid Sternectomy –mesh +bone cement+PMMF
TOTAL LARYNGECTOMY +PP+SLIVARY BYPASS TUBE+PATCH PHARYNGOPLASTY
Free fibula Upto 22 cms thick cortical bone Can be ostetomised –periosteal blood supply Good Skin paddle Good for dental implant skin paddle limited mobility Donor site

DCIA Flap Thick Cancellous bone- healing better Osteotomies easier/less needed Short pedicle Donor site morbidity
Circumferential Pharyngeal reconstruction Jejunal flap Tubed ALT
ACC INFRATEMPORAL FOSSA ICA –MCA BYPASS after tumor resection
POST TRACHEAL RESECTION AND ANASTAMOSIS Tracheal Anastamosis Post Tracheal resection
