A case of macrodactyly associated with neurofiborma of the median nerve, a congenital anomaly of the hand, affecting only one(left middle) finger is reported with a review of the literature. Macrodactyly which is also termed local gigantism, megalodactylism, megalodactylia, or macrodactylism in other literature, is a rare congenital malformation characterized by overgrowth of one or more fingers of hand. Macrodactyly associated with neurofibroma of the median nerve is especially rare. For this reason the following case is presented together with a review of the literature.

Objective:To investigate the clinical manifestations and the effect of peroral endoscopic-assisted laryngeal microsurgery for children with laryngeal neurofibroma, and to provide clinical reference for the diagnosis and treatment of this disease. Methods:The clinical data of 4 children with laryngeal tumors admitted to the Department of Otorhinolaryngology, Children's Hospital of Chongqing Medical University from January 2021 to June 2023 were retrospectively analyzed. Laryngeal tumors were removed by peroral endoscopic-assisted laryngeal microsurgery. One case underwent tracheotomy at the same time, and one case was simultaneously performed with laryngeal T tube placement and tracheotomy. Results:Surgical resection is the best treatment for laryngeal neurofibroma, and laryngeal microsurgery should be actively used for patients with surgical indications.This surgical method has the advantages of good efficacy, minimal invasion, aesthetics and preservation of laryngeal function, which not only ensures safety, but also improves the quality of life after surgery, and has the value of development and promotion.

Intramedullary spinal neurofibroma is extremely rare. A case of cervical intramedullary neurofibroma is presented in a 21-year-old man. Only 20 case have been previously reported in the literature. The site of origin is discussed with various hypotheses.

Although the head and neck region is recognized as the most common location for peripheral nerve sheath tumors, central involvement, particularly in the jaw bones, is quite unusual. Neurofibroma is one of the most common nerve sheath tumors occurring in the soft tissue and generally appears in neurofibromatosis 1 (NF1 or von Recklinghausen's disease). Malignant peripheral nerve sheath tumors (MPNSTs) are uncommon sarcomas that almost always arise in the soft tissue. Here, we report four cases of intraosseous peripheral nerve sheath tumors occurring in the jaw bones and compare the clinical, radiologic, and pathologic findings in order to make a differential diagnosis.

OBJECTIVETo provide the experience for early diagnosis and management of facial nerve neuromas, and to discuss the clinic and imaging feature of facial nerve schwannoma and facial nerve fibroma in 22 cases.

METHODSTwenty cases facial nerve schwannoma and two cases of facial nerve neurofibroma were diagnosed and reviewed retrospectively. Surgical removal were performed through the middle cranial fossa in 2 cases, through intratemporal approach in 8 cases, through intraparotid approach in 2 cases, and combined intra-temporal with out-temporal approaches in 10 cases. Seventeen cases underwent facial nerve graft for repairing a facial nerve defect. Great auricular nerve was used in 3 cases with intratemporal approach and 1 case with intratemporal combined intraparotid approach. Sural nerve graft was used in 5 cases with intratemporal approach and 8 cases with intra-temporal combined intraparotid approach. Two cases were employed two-stage facial muscle flap-plasty.

RESULTSFacial nerve neuromas were totally removed in 21 cases and subtotal neuroma removed in 1 case. In these cases, 20 patients were no recurrence and 1 patient was lost follow-up. One patient with subtotal neuroma removal received Gamma Knife treatment before and after surgery, and this case was no recurrence. The CT imaging of the temporal bone showed that schwannoma was separated "white mass" with smooth margin along the region of facial nerve without intact canal. But neurofibroma locate in enlarge fallopian with intact canal. Magnetic resonance imaging had the advantage of evaluating all segments of the facial nerve and showed continuity of intratemporal and intraparotid mass with the facial nerve. Pathological results indicated that 20 cases were diagnosed as facial nerve schwannoma and 2 cases were neurofibroma.

CONCLUSIONSAlthough tumors originating from the facial nerve are extremely rare, it is possible to make early diagnosis through finding clinical feature and imaging methods. Generally, systematic surgical approach for tumor removal and facial nerve reconstruction should be considered in the cases with facial neurinoma.
