Abstract:
This study intends to make use of neodimum yuttrium
aluminium garnet (Nd: Y AG) lazer as a cure for pseudofolliculitis
barbae and acne keloidalis nuchae (AKN).
For this study a number of nine patients diagnosed as cases of
PFB or AKN were enrolled. The laser device used is available in
the institute of laser-Sudan University of Sciences and technology,
Khartoum Sudan, where the study was conducted. The study was
performed between February and May 2009. Laser system used
Nd: YAG laser with wavelength 1064 nm manufactured by
Dornier Medilas. Nd: Y AG laser parameters used were the
standard mode, non contact application of bare fibre with a power
of 60 Watts, exposure time 0.2 seconds.
All patients were treated under topical anesthesia. A
· questionnaire was designed and filled for each patient. Patients
were submitted to weekly sessions. Lesions, changes were
recorded in each visit. The treatment results were assessed
according to reduction in number of papules and pustules as well

The results were classified as follows
Good results: there is significant reduction in the number of
papules and pustules (approximately 80% of the pre-existing
lesions disappeared,, without hypopigmentation.
Moderate results: The patients showed moderate reduction in
number of papules and pustules (60% of the pre-existing lesions
disappeared) but with hypopigmentation.
Patients who showed good results were 6 patients.
