Laryngeal Schwannoma: A Rare Entity.

Of all schwannomas, 24-45% arise from the head and neck area. Laryngeal schwannoma is an uncommon site. We report a case of a 34-year-old male who presented to the emergency department with worsening sudden onset inspiratory stridor. On direct laryngoscopy, he was noted to have a laryngeal mass, which caused a ball-and-valve effect on the laryngeal inlet, resulting in airway compromise. He was subsequently intubated and admitted to the intensive therapy unit. He underwent endoscopic removal of a bulky submucosal swelling in the supraglottic region using coblation. The post-operative histopathological assessment confirmed features of laryngeal schwannoma. A six-month post-operative follow-up showed no signs of recurrence. Due to the rarity of this condition, the evidence for the most efficient management of these cases is still not clear. Diagnosis is by histology assessment, although clinical evaluation should raise suspicion. Surgery remains the mainstay of treatment with a good overall prognosis. In current literature, the technique of surgical excision varies with different outcomes. We report a case that was managed with micro-laryngoscopy and coblation with good effect.

Temporomandibular joint (TMJ) disorders as first clinical manifestations in external auditory canal cholesteatoma. A case report.

INTRODUCTION AND IMPORTANCE: Cholesteatoma is a common occurrence in the middle ear, whereas cholesteatoma of the external auditory canal (EAC) is a rare condition. We report an unusual presentation of the cholesteatoma in the EAC. CASE PRESENTATION: We report a case of a 67-year-old male presented to the ENT casualty with a longstanding history of left sided squeaky type sound, aggravated whenever he talks or eats. He subsequently had a Computed Tomography (CT) scan of the left petrous bone which identified a left-sided EAC cholesteatoma. Clinical symptoms of EAC cholesteatoma are non-specific, and hence we recommend considering cholesteatoma when patients present with abnormal EAC symptoms and intact tympanic membrane. CLINICAL DISCUSSION: His cranial nerves examination was normal, and the tympanic membrane was intact. His blood count and infective marker were normal. The CT scan of the brain showed a lesion in the left external auditory canal close to the tympanic membrane. The lesion was in contact with the anterior inferior canal wall which had features suggesting bony erosion. Gas bubble seen in the posterior part of the TMJ was in relation to bony erosion of the EAC. CONCLUSION: The cholesteatoma of the EAC is very rare. CT scan can provide detailed information about the extent of external ear canal cholesteatoma, which can be used to identify complications of the disease, in addition to differentiating the external ear canal from the middle ear cholesteatoma. Early recognition of cholesteatoma and prompt treatment is essential to prevent catastrophic complications.
