    Squamous cell carcinoma is the most common malignant neoplasm of the upper aerodigestive
    tract, and presentation is usually at the late stages when the diagnosis is made. Recurrence
    after 1st therapy is common especially in the locoregional area of the tumour. For cancers
    affecting the oral cavity, oropharynx, and mandible, “COMMANDO” (Combined
    Mandibulectomy and Neck Dissection Operation) is one of the surgical approaches which
    constitutes of primary tumour resection, mandibulectomy and neck dissection. We describe a
    case of rapid locoregional recurrence following 1st surgical procedure of bilateral tonsillectomy
    and extended neck dissection of oropharyngeal squamous cell carcinoma in a young healthy
    individual without history of alcohol and tobacco abuse involving the right buccal region which
    after positron emission tomography was done, showed involvement of right pterygoid muscles,
    right-sided tongue muscle, and right mandible. The patient underwent redo salvage surgery
    and reconstruction with anterolateral thigh flap.

    Solitary fibrous tumours of the head and neck region are
    extremely rare. The clinical diagnosis is often difficult to
    establish, and this lesion may be indistinguishable from other
    soft tissue neoplasms. An 18-year old Chinese gentleman
    presented with a painless right submandibular swelling which
    was increasing in size for eight months. A computed
    tomography scan showed a well-defined solid mass measuring
    about 2.0 x 2.96 cm in the submandibular region. The tumour
    was resected and was confined within its capsule.
    Immunohistochemical staining was strongly positive for CD34,
    CD 99, and vimentin and negative for desmin, smooth muscle
    actin (SMA), cytokeratin, S100 and CD68. The microscopic and
    immunohistochemical profile were compatible with solitary
    fibrous tumour. Distinguishing solitary fibrous tumours from
    various spindle neoplasms can be difficult. In view of the
    resemblance, immunohistochemical staining can help
    differentiate solitary fibrous tumour from spindle neoplasm.

    An acquired persistent tracheopharyngeal fistula secondary to an infected tracheopharyngeal voice prosthesis is a common cause of recurrent aspiration pneumonia in a postlaryngectomy patient. We report a case of a successfully treated tracheopharyngeal fistula whereby both the sternocleidomastoid muscles were used as muscular flaps to close the defect and its outcome.

    Preoperative radiological assessment of parotid tumours represents a crucial step in the planning of a parotidectomy in order to avoid post-operative facial nerve paralysis. The purpose of this study is to determine the reliability of the novel 'M-line' in predicting the facial nerve position and compare it to various radiological methods in the same context. 66 patients whom had underwent parotidectomy for parotid tumours from January 2012 to February 2021 were analyzed. Parotid tumour location were identified using the retromandibular vein, facial nerve line, Conn's arc, Utrecht line and the 'M'-line were compared to the intraoperative location of parotid tumours.The 'M'-line is a novel hypothetical line (drawn between the lateral surface of the mandible to the lateral border of the mastoid process) used to identify the location of the facial nerve radiologically. The 'M-Line' and other methods of radiological assessments were associated with statistical significance in predicting if the parotid tumours were superficial or deep to the facial nerve (p-value
