Aim to determine the effectiveness of Endolaryngeal Core Biopsy and Fine Needle aspiration Cytology in endophytic or submucosal laryngeal malignancies. Background: Endophytic and submucosal laryngeal tumours pose as diagnostic as well as management challenges to the head and neck surgeon. Identifying the tumour location and extent of disease is crucial for the surgeon to determine the treatment options and the potential outcomes. Persistent laryngeal edema following radiotherapy also presents with a diagnostic dilemma, as distinguishing between recurrent laryngeal carcinoma and radiotherapy sequels; which include fibrosis, oedema and soft tissue and cartilage necrosis, can be confusing and punch biopsies performed in such cases would more than often yield inadequate or superficial tissue. Using a core biopsy gun for acquiring biopsy specimen is known to have more cellular material, less damage to the surrounding structure depth control, immediate analysis with higher accuracy rates. Technique: Patients with suspected laryngeal malignancy are initially evaluated with flexible endoscopy with Narrow band imaging (NBI) and appropriate imaging. These patients are subjected to Microlaryngoscopic under general anaesthesia. A core biopsy gun is used to obtain samples from the suspicious area. Simultaneously, with the aid of microlaryngeal forceps, an FNAC is also done and sent for rapid processing. Conclusion: Trucut biopsy is a novel diagnostic tool that can be commonly used in early laryngeal malignancies especially in those cases where there is strong suspicion of malignancy and the lesion is found to be submucosal. Clinical significance: we noted that a routine DL scopy and Biopsy in submucoal disease often results in a acquiring a non-representative sample as well as causing inadvertent trauma to the surrounding mucosa. We encourage Laryngeal surgeons to routinely use Core biopsies and FNAC during routine microlaryngeal Examination for better yield, faster diagnosis and faster planning of treatment protocols.
