Removing a head and neck cancer often means removing skin, mucosa and sometimes bone along with it, leaving a gap that affects facial contour, chewing and speech. To rebuild that gap, surgeons may take tissue — skin, muscle, occasionally bone — from another part of the body along with its own blood vessels, move it into place, and reconnect vessels only one to three millimetres wide under a microscope. This is called free flap reconstruction. The outer lower leg bone, the outer front of the thigh, and the forearm are common places to take tissue from. One operation therefore leaves two wounds: the recipient site where the tissue was placed, and the donor site where it came from.
The first days to roughly two weeks are the most closely watched period, and the reason is the reconnected blood vessels. The transferred tissue receives blood through those vessels alone, so a clot or sustained pressure can cut off its supply. That is why nurses check the flap every few hours for colour, temperature, swelling and Doppler signal. A flap that turns pale or dusky blue, feels distinctly cooler than surrounding skin, swells suddenly, or begins to ooze at the suture line should be reported without waiting.
The same reasoning explains the detailed rules about position and pressure: avoid turning or bending the neck sharply, keep mask straps, eyeglass arms, pillow edges and tracheostomy ties from crossing over the flap, rest with the upper body slightly raised, and stay warm. Cold and smoking, including second-hand smoke, both narrow blood vessels and are generally discouraged throughout recovery.
The drains in the neck and in the leg collect pooled blood and tissue fluid to limit swelling and haematoma. When they come out usually depends on the volume and colour of drainage over twenty-four hours rather than on which post-operative day it is, so the facial drain and the leg drain may be removed days apart. If the area swells again after removal, or feels like a fluid pocket that shifts under gentle pressure, it is worth having it looked at.
The donor leg recovers on its own schedule. If a skin graft was placed over the harvest site, a splint or compression dressing and time with the leg elevated are often needed until the graft takes. When walking resumes, and how much weight may be placed on the leg, is decided by wound condition, whether a graft was used, swelling, and ankle and toe strength and sensation — not by a fixed date. Progression typically moves from ankle movements in bed to sitting, standing, and walking with an aid. Neither staying completely still out of fear of wound breakdown nor pushing through pain helps recovery, so it is worth asking the team exactly which stage is permitted right now.
Speech and eating follow their own timeline. After reconstruction inside the mouth or jaw, swelling, a tracheostomy tube and a feeding tube can delay voice and swallowing, and speech may sound slurred for a while. Swallowing assessment and speech rehabilitation are staged as the swelling settles. Recovery is not a straight line; better days alternating with worse ones is the ordinary pattern rather than a warning sign in itself.
The final pathology report after surgery describes the resection margins, lymph nodes and any nerve or vessel involvement, and it is the basis for deciding whether further treatment is needed. If radiotherapy is added, care of the reconstructed area and of the mouth changes, and a dental assessment may come first. Fever, wound odour, spreading redness, or difficulty breathing are reasons to call rather than wait for the next appointment.
