On harelip and cleft palate

The work presents a systematic survey of congenital fissures affecting the lip, alveolus, and palate, classifying median, unilateral and bilateral harelip, facial and mandibular clefts, and cleft palate; it examines frequency, anatomical variations, and embryological development, considers proposed causes, and describes feeding adaptations. The major practical portion gives detailed operative techniques, choice of incisions, instruments, sutures, and postoperative care, illustrated with diagrams and clinical examples; historical methods and comparative animal cases are noted to contextualize surgical advances and decision-making.
