In developing countries like Pakistan the cost effectiveness and patient convenience in any treatment modality is a question of major concern. The purpose of this study was two-fold; first to report our experience with a high-dose rate Iridium-192 surface mould brachytherapy of keloid scars after surgical excision, using different radiation treatment regimen and second to establish the most convenient and cost effective treatment protocol having no compromise on the treatment outcomes.

From January 2012 to April 2015 a total 51 patients with 65 keloid lesions underwent postoperative Iridium-192 high-dose rate surface mould brachytherapy. The dose regimen used was: 8 Gy in a single fraction, 10 Gy in a single fraction, 15 Gy in three fractions and 18 Gy in three fractions. The median follow-up period was 33 months (range 15–53 months).

The success rates were 57·2, 89·5, 85 and 89·5% for the treatment regimen of 8 Gy/F×1, 10 Gy/F×1, 5 Gy/F×3 and 6 Gy/F×3, respectively. Grade 2 or above radiation induced toxicity was not observed.

The results of this study show that a dose regimen of 10 Gy (biological effective dose=20 Gy) in a single fraction have comparable results with a dose regimen of 15 Gy in three fractions or 18 Gy in three fractions. 10 Gy in a single fraction is therefore the most convenient and cost effective dose regimen for the management of keloid scars in developing countries like Pakistan, while 8 Gy in a single fraction is considered suboptimal and discouraged in practice.

Conchal cartilage is frequently used in rhinoplasty, but donor site morbidity data are seldom reported. This study aimed to investigate the complications of conchal cartilage harvesting in rhinoplasty.

A retrospective chart review of 372 patients who underwent conchal cartilage harvesting for rhinoplasty was conducted. Data regarding patient demographics, types of nasal deformities, graft usage and complications were analysed.

A total of 372 patients who underwent conchal cartilage harvesting for rhinoplasty were enrolled. The harvested conchal cartilage tissues were used in a variety of applications: tip graft, dorsal graft, septal reinforcement and correction of nostril asymmetry. Nine cases (2.4 per cent) with donor site morbidities were identified, including four cases (1.1 per cent) with keloids and five cases (1.3 per cent) with haematomas.

Conchal cartilage harvesting is a safe and useful technique for rhinoplasty, with a low complication rate. However, patients should be informed about the possibility of donor site morbidities such as keloids and haematomas.

To study the role of mitomycin C in reducing keloid recurrence.

Prospective, randomised, controlled trial.

Tertiary care referral centre.

Case series of 20 patients presenting with 26 pinna swellings, mostly following ear piercing.

We used the technique of surgical shave excision combined with topical application of mitomycin C and secondary wound healing, in all 26 pinnae.

Patients were followed up six to 24 months post-operatively. No recurrences were noted during this period.

Keloids are fibrotic lesions resulting from abnormal wound healing. The uncontrolled proliferation of normal tissue healing processes results in scarring that enlarges well beyond the original wound margins. Successful treatment of keloids remains a challenge because this disease process has a high propensity for recurrence. Various therapies have previously been reported, and success rates are highly variable. We believe that shave excision followed by topical mitomycin C application is a promising treatment option for the management of pinna keloids.
