BACKGROUND: Lesions lateral to the lower brainstem in an area extending from the foraminae of Luschka to the foramen magnum are rare and include different pathologies. There is no consensus on an ideal surgical approach. METHOD: To gain access to this area, we use the midline suboccipital subtonsillar approach (STA). This midline approach with unilateral retraction of the cerebellar tonsil enables entry into the cerebellomedullary cistern. CONCLUSIONS: The STA offers excellent access with a panoramic view of the cerebellomedullary cistern and its structures and therefore can be useful for a number of different pathologies in the lower petroclival area...

BACKGROUND: Treatment of Chiari malformation can include suboccipital decompression with resection of one cerebellar tonsil. Its effects on ocular motor and cerebellar function have not yet been systematically examined. OBJECTIVE: To investigate whether decompression, including resection of one cerebellar tonsil, leads to ocular motor, vestibular, or cerebellar deficits. PATIENTS AND METHODS: Ten patients with Chiari malformation type 1 were systematically examined before and after (1 week and 3 months) suboccipital decompression with unilateral tonsillectomy...

REVIEW
M-N Theodoraki, J A Veit, T K Hoffmann, J Greve
BACKGROUND: The incidence of synchronous bilateral tonsil carcinoma seems to be underreported. For adequate oncologic treatment, it is mandatory to remove all primaries to prevent recurrence or metachronic disease. The purpose of this manuscript is to provide a comprehensive review on this topic and to emphasize the need of bilateral tonsillectomy in cases of cancer of unknown primary (CUP) as well as in the case of a unilateral tonsillar carcinoma. MATERIAL AND METHODS: A systematic review of the literature was performed for "bilateral tonsillar neoplasm", "synchronous cancer of the oropharynx" and "cancer of unknown primary in head and neck"...

INTRODUCTION: The peritonsillar space is defined as the area between the palatine tonsillar capsule medially and the superior pharyngeal constrictor muscle laterally. Unilateral peritonsillar abscess (PTA) is more common than the bilateral condition. To the best of our knowledge, only 13 cases of bilateral PTA have been reported worldwide; this is the first case reported from Saudi Arabia. PRESENTATION OF CASE: We present a case involving a 16-year-old boy who presented to the emergency department with a5-day history of sore throat, dysphagia, trismus, drooling, and a muffled "hot-potato" voice, but with no symptoms of airway compromise...

OBJECTIVE: Solitary mass lesions of the palatine tonsils are rare in children. While a tonsillar mass can be concerning for a neoplasm, benign conditions may present with a mass arising from the surface of the palatine tonsils in children. We describe clinical and histopathological characteristics of a lymphoid polyp in a child with unilateral tonsillar mass. METHODS: Retrospective chart review. RESULTS: A 6-year-old girl presented for evaluation of recurrent acute tonsillitis and a mass on the left palatine tonsil...

OBJECTIVES: When physicians encounter patients with headache or facial pain (preeruptive pain) associated with acute herpes zoster of the head, especially before the appearance of characteristic skin eruptions (preeruptive phase), they typically find it difficult to make clinical impressions and apply appropriate diagnostic or therapeutic procedures. The objectives of this study were to describe the clinical characteristics of headache or facial pain associated with acute herpes zoster of the head and to elucidate the association between the manifestation of these symptoms in the preeruptive phase and incoming herpes zoster...

Tonsillectomy and/or adenoidectomy is the most common surgical procedure in ENT practice and the malignancy rate of tonsillar tissue is very rare. The purpose of the present study is to investigate the necessity of routine histopathologic examinations following tonsillectomy and/or adenoidectomy surgeries. A total of 385 patients between the age of 5 and 16 years who were admitted to our ENT clinic and underwent adenoidectomy and/or tonsillectomy between October 2008 and July 2015 participated in the study...

The commonest cause of head and neck malignancy in pediatric patients is lymphoma. A particular case is the tonsillar lymphoma. Even though unilateral tonsillar enlargement represents an ominous sign for neoplasia, clinical manifestations vary and are non-specific. Therefore, a delayed diagnosis is performed which compromises optimal therapy and hinders the prognosis. We present the case of a 5-year-old boy who was initially diagnosed with obstructive sleep apnea, without reported systemic complaints. Asymmetric tonsillar hypertrophy created the premises for performing a tonsillectomy to rule out malignancy...

Lymphoepithelial cyst (LEC) is the most commonly encountered congenital neck pathology in the lateral part of the neck. A 66-year-old woman presented to the ENT clinic due to difficulty in swallowing persisting for approximately 1 year. Magnetic resonance imaging revealed a cystic mass at right tonsil. Surgery was performed due to this unilateral tonsillar mass, which was excised together with the right tonsil. LEC was diagnosed at histopathological examination. LEC in the palatine tonsil is rare, and only a few cases have been reported in the literature...

BACKGROUND: Tonsilloliths are calcified concretions that develop in tonsillar crypts. They are usually small and asymptomatic, so they are found accidentally during routine dental radiogrphy procedure. Large tonsilloliths can occur with clinical signs and symptoms. The purpose of this study was to evaluate the prevalence and patterns of palatine and adenoid tonsilloliths in cone-beam computed tomography (CBCT) images. MATERIALS AND METHODS: In this cross-sectional study, 0...

Tonsillar lymphoma usually presents as unilateral or bilateral enlargement or as an ulcerative or fungating lesions. Most lymphomas that involve the tonsils are diffuse large B-cell lymphomas and primary low grade lymphomas are exceptional. We report a case of primary B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) affecting tonsils with interfollicular pattern of infiltration in a 54-year-old female who clinically presented with bilateral tonsillar enlargement, sore throat, dysphagia and respiratory difficulty, unresponsive to the conservative treatment...

A potential advantage of intensity-modulated proton therapy (IMPT) over intensity-modulated (photon) radiation therapy (IMRT) in the treatment of oropharyngeal carcinoma (OPC) is lower radiation dose to several critical structures involved in the development of nausea and vomiting, mucositis, and dysphagia. The purpose of this study was to quantify doses to critical structures for patients with OPC treated with IMPT and compare those with doses on IMRT plans generated for the same patients and with a matched cohort of patients actually treated with IMRT...

OBJECTIVES/HYPOTHESIS: In the setting of considerable variation of pharyngeal palatine tonsil fluorine 18 fluorodeoxyglucose (FDG) uptake, we mostly rely on the asymmetry between the left- and right-sided tonsils to identify underlying malignancy. The current study evaluates the FDG positron emission tomography (PET)/computed tomography (CT) findings within the contralateral tonsil among patients who had unilateral tonsillectomy and analyzes the cancer incidence in the contralateral tonsil with high FDG avidity...

We report a constellation of cervical polyneuropathies in a patient treated with concurrent bortezomib, cetuximab, and cisplatin alongside intensity modulated radiotherapy for carcinoma of the tonsil with neck metastasis. The described deficits include brachial plexopathy, cervical sensory neuropathy, and oculosympathetic, recurrent laryngeal, and phrenic nerve palsies within the ipsilateral radiation field. Radiation neuropathy involving the brachial plexus is typically associated with treatment of breast or lung cancer; however, increased awareness of this entity in the context of investigational agents with potential neuropathic effects in head and neck cancer has recently emerged...

This study is aimed at updating our institution's experience with definitive radiotherapy (RT) for squamous cell carcinoma of the tonsil. We reviewed 531 patients treated between 1983 and 2012 with definitive RT for squamous cell carcinoma of the tonsil. Of these, 179 patients were treated with either induction (n = 19) or concomitant (n = 160) chemotherapy. Planned neck dissection was performed on 217 patients: unilaterally in 199 and bilaterally in 18 patients. Median follow-up was 5.2 years for all patients (range 0...

OBJECTIVES:  In the pre-human papillomavirus (HPV) era, unilateral radiation therapy (URT) for tonsil cancer was associated with low contralateral failure rates and had less toxicity than bilateral radiation therapy (BRT). This study explores the validity of URT in HPV-positive tonsil cancers. METHODS:  Tonsil squamous cell carcinomas (SCC) treated (typically with 70 Gy radiation and Cisplatin-based chemotherapy) between 2001 and 2007 were reviewed. Retrospective p16 immunohistochemistry staining was undertaken...
