Cranial Nerves: Types Part I

Cranial Nerves: Types Part I

Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

Cranial Nerves: Types Part II

Cranial Nerves: Types Part II

Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
Facial Nerve (Cranial Nerve VII)
Cranial nerve VII, or the facial nerve,...

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Summary

Malignant schwannoma, a rare nerve sheath tumor, can occur in the head and neck. This case highlights successful treatment of a recurrent malignant schwannoma with surgery and radiotherapy, showing potential for good outcomes.

Area of Science:

Oncology
Surgical Oncology
Head and Neck Surgery

Background:

Malignant schwannoma is a rare peripheral nerve sheath tumor, comprising 5-10% of soft tissue sarcomas.
Cervico-facial localization is exceptionally rare, accounting for only 1% of mandibular tumors.

Observation:

A 64-year-old male presented with malignant schwannoma of the inferior dental nerve.
Initial resection was followed by recurrence and proximal extension, necessitating transfer to a specialized center.

Findings:

The patient underwent wide surgical resection, ipsilateral neck dissection, and postoperative external radiotherapy.
No recurrence was observed after a 1-year follow-up period.

Implications:

Diagnosis of cervico-facial malignant schwannoma can be challenging, even with advanced imaging; histological confirmation is crucial.
While prognosis is often guarded due to recurrence risk, multimodal treatment including surgery and radiotherapy can be effective.
This case underscores the importance of aggressive surgical management and adjuvant therapies for rare head and neck malignancies.
