Abstract

During reconstructions of the head and neck regions with a scapular or a scapular osteocutaneous flap, it is usually necessary to reposition the patient twice and prepare the operating field three times for removal of tumor, harvesting the flap, and reconstruction. This is one of the main disadvantages of the scapular flap. We have used the pull-through technique to reduce the number of changes in position that are required. In addition, the ischaemic time of the flap is also substantially reduced. The flap is first raised and then tunneled through the axilla to lie passively on the chest while the tumor is excised. These procedures have been followed in 13 cases of scapular and scapular osteocutaneous flap with no problems.

Chest wall irradiation with MLC-shaped photon and electron fields.

PURPOSE: To improve the treatment technique for chest wall irradiation, using the multileaf collimator (MLC) of the MM50 Racetrack Microtron to shape both photon and electron beams, and to check the dose delivery in the match-line region of these fields for the routine and improved technique. METHODS AND MATERIALS: Using diode and film phantom measurements, the optimal number of photon beam segments and their positions relative to the electron beam were determined. On phantoms, and during actual patient treatment using in vivo dosimetry, the dose homogeneity in the match-line region was determined for both the routine and improved techniques. RESULTS: Three photon beam segments (9-mm gap, perfect match, and 9-mm overlap) were used to match the electron beam, resulting in minimum-maximum dose values in the match-line region of 88-109%, compared to 80-115% for the routine technique (2 photon beam segments). During patient treatment, the average minimum and maximum dose values were 95% and 115%, respectively, compared to 78% and 127%, respectively, for the routine technique. The interfraction variation in dose delivery was reduced from 11.0% (1 SD) to 4.6% (1 SD). The actual treatment time was reduced from 10 to 4.5 min. CONCLUSION: Using the MLC of the MM50 to shape both photon and electron beams, an improved treatment technique for chest wall irradiation was developed, which is less labor intensive, faster, and yields a more homogeneous, and better reproducible dose delivery.
