<p class="abstract">Sinonasal diseases are serious health issues found in the clinical practice. Sinonasal diseases are often associated with anatomical variants in the sinonasal tract. There are numerous sinonasal anatomical variants found frequently in computed tomography (CT) scans of the paranasal sinuses. Middle turbinate concha bullosa is a common anatomical variant found in the nasal cavity. Pneumatization of the middle turbinate is called as concha bullosa. The pneumatization of the middle turbinate is mostly via the anterior ethmoidal air cells. Pneumatizations through posterior ethmoid air cells are also reported. There are three types of concha bullosa such as lamellar, bulbous and extensive. Majority of the patients with middle turbinate concha bullosa are asymptomatic. Sometimes this is accidentally detected during proper evaluation of the headache. Sometimes the middle turbinate concha bullosa is associated with chronic sinusitis. However, there are very few literatures which correlate the middle turbinate concha bullosa and chronic sinusitis. Although chronic sinusitis is a clinical diagnosis, the imagings like CT scan are useful to assess the extent of the disease and demonstrate the sinonasal anatomy. CT scan of the paranasal sinuses and diagnostic nasal endoscopy are important tests useful for evaluation of the middle turbinate concha bullosa and its relations with chronic sinusitis. This review article discusses on the details of the middle turbinate concha bullosa and its relationship with chronic sinusitis.</p>

“…This lesion usually originates in isolation, although ABC may sometimes be associated with other bony pathology. 14 Approximately 30% of ABCs are secondary to certain lesions such as giant cell tumor, osteoblastoma, chondroblastoma, chondromyxoid fibroma, fibrous dysplasia or non-ossifying fibroma. 15 The exact nature of histogenesis of ABCs are still unclear and it is classified into indeterminate tumor, intermediate malignancy and locally aggressive.…”

Aneurysmal bone cysts (ABCs) are benign, vascular and cystic bony tumors which can be rapidly expanding and locally cause destruction of the surrounding tissue. ABCs in the head and neck area are usually found in patients with younger age group. ABC in the head and neck region of children may vary in presentations and severity. ABCs are commonly found in mandible, sinonasal tract and cranium in head and neck region. Imaging and histopathological examinations confirm the diagnosis. Complete surgical excision is the treatment of choice. ABC which is secondary to underlying bone pathology like osteoblastoma may refractory to treatment. ABC in the head and neck region are uncommon and should be considered as differential diagnosis of bony and vascular lesions in the locations like mandible, sinonasal area, cranium, mastoid bone and spine. The review article includes case series, case reports and original research on ABCs manifesting in the head and neck area published in the English language. All literatures identified via Scopus, Google scholar, Medline and PubMed were analyzed individually. Articles of ABCs included according to specified eligibility criteria. The total number of articles were 78 (41 case reports; 37 cases series; 8 original articles). ABCs rapidly grow with expansile manner and result in destruction of bone and surrounding tissue in the head and neck region, so clinicians must think about this clinical entity to diagnose correctly and treat appropriately. The aim of the article is providing a comprehensive review of the ABC in the head and neck region of the pediatric patients.

“…If the tumor extends into the external ear, computed tomography (CT) scan and magnetic resonance imaging (MRI) are helpful to assess the extent of the lesion. 6 Wide surgical excision is the treatment option. The schwannomas of the pinna are not widely discussed in the core surgical literature.…”

Schwannoma of the pinna: a narrative review

Schwannomas are uncommon and benign neurogenic tumors that originate from the nerve sheath of the myelinated nerves. It can be found in any peripheral, cranial or autonomic nerves which contain Schwann cells. It is also called neuroma, nerve sheath tumor and neurilemmoma. Schwannomas in the head and neck region often present as painless swelling. The growth of schwannoma of the pinna causes an aesthetic alteration of the pinna. Schwannoma is a rare tumor of the pinna. The diagnosis of schwannoma is confirmed by histopathological study and immunohistochemistry. Histopathologically, it shows encapsulated, well-circumscribed lesions composed of different cellular patterns and arrangements. Histologically, the hallmark of schwannomas is the pattern of alternating Antoni A and Antoni B areas. The treatment of choice for schwannoma of the pinna is complete surgical excision. Recurrence following complete excision of the schwannoma is rare. Because of their rarity, these tumors are often not included in the differential diagnosis of the mass on the pinna. Preoperative suspicion and awareness are very important for schwannoma of the pinna to avoid delayed diagnosis and treatment. There is not much literature on the schwannoma of the pinna, indicating that this clinical entity is neglected. The objective of this article was to provide a comprehensive review of the schwannoma of the pinna including its epidemiology, etiopathology, clinical presentations, diagnosis and treatment.
