A method for planning a current medical procedure to be performed on a body part of a current patient includes obtaining a current first representation of a surface of the body part of the current patient, and either obtaining a representation of a desired result surface for the current medical procedure or selecting parameters for the current medical procedure. The method further includes retrieving at least one best matching record from a database of records of previously performed medical procedures of previous patients, based on a similarity criterion. Each record includes: parameters of a previously performed procedure of the previously performed medical procedures, a first representation of the body part of the previous patient prior to performance of the previously performed procedure, and a second representation of a body part of the previous patient after the performance of the previously performed procedure. The method further includes determining parameters of the current medical procedure based on the parameters of the retrieved record, or generating a representation of a predicted result for the current medical procedure on the body part of the current patient based on the retrieved record.
