Difference in clinical presentation and their significance in oral squamous cell carcinoma: A retrospective analysis.

BACKGROUND: Oral squamous cell carcinoma (OSCC) remains the most common cancer among Indian men. OSCC involving the tongue and bucco alveolar complex (BAC) behaves differently. Nevertheless, the differences in clinical features and symptoms between the two subsites and their relation to pathology remain largely unexplored. STUDY DESIGN: The study compared various clinical parameters and pathological factors between tongue cancer patients and patients with BAC cancer. RESULTS: Among 474 patients, 232 had tongue cancer and 242 had BAC cancer. Except for the ulcer, 30% of patients with OSCC were asymptomatic at presentation. Compared to tongue cancers, lesions confined to BAC present at an advanced stage (P = 0.006). Multivariate analysis showed that dysphagia in tongue cancer (P = 0.020) and external swelling or lesion in BAC cancers (P = 0.002) were significant predictors of an advanced stage of the disease. On histopathology, perineural invasion (PNI) was significantly associated with tongue (P = 0.008) compared to BAC cancers (P = 0.015). Cancers of the tongue with pain and referred otalgia had a significantly higher depth of invasion (DOI), compared to those without pain (DOI - no pain 6.9 mm, pain 9.9 mm, and referred otalgia 11.4 mm). CONCLUSIONS: Patients with OSCC present late and in an advanced stage of the disease. Among tongue cancers, clinical history of pain was significantly associated with DOI and PNI, the significance of which needs to be prospectively analyzed. Clinical history in OSCC can be used as predicting factor for an advanced pathological stage of the disease. It also had an influence on various pathological characters, which is subsite specific.

Are Throat Pain and Otalgia Predictive of Perineural Invasion in Squamous Cell Carcinoma of the Oropharynx?

PURPOSE: Head and neck cancer is often associated with pain and perineural invasion (PNI). The purpose of this study was to determine the association of pain complaints and the microscopic identification of PNI in patients with oropharyngeal squamous cell carcinoma (OPSCC). PATIENTS AND METHODS: A retrospective cohort study was performed including patients diagnosed with OPSCC from 2010 to 2019. Patients diagnosed and operated on with curative intent at 2 institutions were included. The primary predictor variable was pain (measured as no pain, ear pain, throat pain, or simultaneous pain). Other variables were patient demographics, p16 status, and TNM staging. The primary outcome variable was the histologic presence of PNI. Chi-square analysis was performed to test for any significant associations between pain, T stage, overall stage, and p16 status in relation to PNI outcome. Multivariate logistic regression analysis was used to control for cancer staging variables when testing the association between pain and PNI. RESULTS: The final sample was composed of 157 subjects of whom 126 were men. The mean age was 59.7 years. Seventy-seven (49.0%) presented with no pain, while 35 (22.3%), 39 (24.8%), and 6 (3.8%) presented with both throat/ear pain, throat pain only, and ear pain only, respectively. Patients with simultaneous pain had 3.41 times higher odds of PNI compared to the no pain group (P = .02), although only pathologic T stage 4 and a diagnosis on the base of the tongue were independent postoperative predictors of PNI (P < .05). CONCLUSIONS: Our study demonstrates that otalgia is a preoperative predictor of PNI in OPSCC and also demonstrates a trend of increasing pain complaints with PNI.

Evaluation and Management of Otalgia.

Otalgia can be broadly categorized into primary otologic causes and secondary nonotologic causes. Isolated otalgia in the absence of hearing loss, otorrhea, or abnormal otoscopic findings is typically secondary to referred pain from nonotologic causes, as the sensory nerve supply to the ear arises from 4 cranial nerves and the cervical plexus. The most common causes of primary otalgia are acute otitis media and otitis externa, whereas the most common causes of secondary otalgia are temporomandibular joint disorders and dental pathology. Persistent unilateral ear pain and other alarm symptoms warrant further evaluation for possible neoplasm.

Secondary Otalgia: Referred Pain Pathways and Pathologies.

Otalgia is very common, and when the cause of ear pain is not identified on otoscopy and physical examination, cross-sectional imaging is routinely used to evaluate for potential sources of referred ear pain (secondary otalgia). Innervation of the ear structures is complex, involving multiple upper cervical, lower cranial, and peripheral nerves, which transit and innervate a large anatomic territory involving the brain, spine, skull base, aerodigestive tract, salivary glands, paranasal sinuses, face, orbits, deep spaces of the neck, skin, and viscera. Interpreting radiologists must be familiar with these neural pathways and potential sources of secondary otalgia. The purposes of this review are to detail the currently proposed mechanisms of referred ear pain, review the salient neuroanatomy of the complex pathways responsible for secondary otalgia, highlight important benign and malignant etiologies of referred ear pain, and provide a structured search pattern for approaching these challenging cases on cross-sectional imaging.

Otalgia.

BACKGROUND: Otalgia is frequently seen in general practice. It can be broadly divided into primary otalgia, which includes the diseases occurring largely within the ear, or secondary otalgia, which is pain referred to the ear by travelling along cranial nerves that supply both the ear and referred region. The causes of secondary otalgia may require more extensive examination and investigation to define the aetiology. OBJECTIVE: The aims of this article are to outline the most common causes of otalgia seen in general practice, and provide a pragmatic approach to initial assessment and deciding when to refer for specialist review. DISCUSSION: The most common cause of primary otalgia is infection. Other causes require a greater index of suspicion. Specialist referral could be made if there are complications of primary otalgia or if a secondary cause needs to be excluded in a patient with a normal otology examination.

A case of nasal septal deviation-induced rhinogenic contact point otalgia.

Recently, the author experienced a case of intractable right-sided otalgia in a 17-year-old male patient. The pain was intermittent and frequently radiated to the right forehead and periorbital region. He had received unsuccessful medical treatments for migraine headache. The otoendoscopic examination revealed a normal tympanic membrane. Nasal endoscopy showed only an intranasal mucosal contact point between the septal crest and the right inferior turbinate, without other signs of sinus inflammation. Topical application of an anesthetic and vasoconstrictive solution-soaked cotton pledget at the intranasal contact area made the patient experience a significant improvement of symptoms. After surgical removal of the mucosal contact point by conventional septoplasty and turbinoplasty, he experienced significant relief of symptoms and complete recovery. Here, the author report a case of intractable otalgia induced by nasal septal deviation with review of literatures, and suggestion for new disease entity of rhinogenic contact point otalgia induced by nasal septal deviation is carefully made.

The nervus intermedius: a review of its anatomy, function, pathology, and role in neurosurgery.

BACKGROUND: Geniculate neuralgia, although uncommon, can be a debilitating pathology. Unfortunately, a thorough review of this pain syndrome and the clinical anatomy, function, and pathology of its most commonly associated nerve, the nervus intermedius, is lacking in the literature. Therefore, the present study aimed to further elucidate the diagnosis of this pain syndrome and its surgical treatment based on a review of the literature. METHODS: Using standard search engines, the literature was evaluated for germane reports regarding the nervus intermedius and associated pathology. A summary of this body of literature is presented. RESULTS: Since 1968, only approximately 50 peer-reviewed reports have been published regarding the nervus intermedius. Most of these are single-case reports and in reference to geniculate neuralgia. No report was a review of the literature. CONCLUSIONS: Neuralgia involving the nervus intermedius is uncommon, but when present, can be life altering. Microvascular decompression may be effective as a treatment. Along its cisternal course, the nerve may be difficult to distinguish from the facial nerve. Based on case reports and small series, long-term pain control can be seen after nerve sectioning or microvascular decompression, but no prospective studies exist. Such studies are now necessary to shed light on the efficacy of surgical treatment of nervus intermedius neuralgia.

Microvascular decompression may be an effective treatment for nervus intermedius neuralgia.

OBJECTIVE: To report microvascular decompression as a possible effective treatment for patients with nervus intermedius neuralgia, and to contribute to the literature regarding both this syndrome and this specific form of treatment. METHOD: Case report of a patient with intermedius neuralgia. The main complaint was severe otalgia in the area innervated by the nervus intermedius, possibly caused by neurovascular compression of the nervus intermedius by the anterior inferior cerebellar artery. Microvascular decompression was undertaken, with good results. RESULTS: Post-operatively, the patient felt immediate and total relief of her otalgia, with normal facial nerve function and no otological morbidity. One year post-operatively, she was still free from otalgia. CONCLUSION: Patients with nervus intermedius neuralgia who do not respond to medical treatment may benefit from microvascular decompression.

Therapeutic properties and tolerance of procaine and phenazone containing ear drops in infants and very young children.

UNLABELLED: Since ear pain is often intolerable in very young children with acute otitis media (AOM), a safe pain reduction is indispensable both from the medical as well as from the ethical point of view. METHODS: To confirm the safety and therapeutic properties of ear drops (Otalgan) consisting of the short acting local anesthetic procaine hydrochloride (CAS 51-05-8) and the anti-inflammatory component phenazone (CAS 60-80-0), a multi-center, non-interventional post marketing surveillance (PMS) study was performed in 428 children (f/m: 45.6%/ 54.4%) aged between 0 and 6 years (mean 3.44 ys). Otalgia as the overall diagnostic criterion present in all children was allotted to otitis media in 398 (93%) and to otitis externa in 28 patients (6.5%), while in two patients, both diagnoses were documented. RESULTS: No adverse drug reactions (ADR) to the target medication have been detected during the entire study. The evaluation of tolerance by the physicians (mean score 1.38) and by the children/ parents (mean score 1.48) was in compliance with the absence of ADR. The drug tolerance was rated by the physicians in 99.8% of the cases as very good (62.2%; n = 266) or good (37.6%; n = 161). In one child (0.2%), the tolerance was evaluated by the physician as moderate. The judgement of parents revealed for all children either a very good (51.9%; n = 222) or good (48.1%; n = 206) evaluation of tolerance. The target medication was tolerated well, independent of the duration of treatment (2 to 10 days with a median of 5 days), of the daily dose and of the accumulated dose per treatment cycle, i.e. longer treatments and higher doses were not associated with a worsening of tolerance evaluations. Even in the highest dose class of over 100 drops per treatment cycle, no changes of tolerance could be revealed. As far as can be derived from non-controlled observational data, the results also confirm the known efficacy profile of the target medication in children. Under the treatment, the initial mean pain score of 2.33 was reduced by nearly 93% down to 0.17, accompanied by a corresponding normalization of the otoscopic findings of the ear canal and the tympanic membrane, and by the Improvement of the general condition. In 95.3% of the children, the physicians rated the efficacy of the target medication as very good (n = 156; 36.4%) or good (n = 252; 58.9%) while in 14 patients (3.3%) the efficacy was scored as moderate, in 4 patients (0.9%) as minimal and in two patients as inadequate (0.5%). The results also demonstrate that with the use of the target medication for local symptomatic treatment of pain in the outer ear canal and in AOM in children, the use of antibiotics in most of the cases can be avoided. CONCLUSIONS: The findings are in full accordance with the results of former clinical studies, with positive evaluations of ototoxicity and with accumulated pharmacovigilance data showing that since introduction of the drug in 1911, no ADR have ever been reported in children. The study confirms that the target medication provides a safe and rapid pain reduction and improvement of inflammation in very young children suffering from painful acute inflammatory ear conditions.

Symptomatic postsurgical traumatic neuromas.

HYPOTHESIS: Growing nerve fibers from the stumps of amputated sensory nerves can form traumatic neuromas within inner or middle ear postsurgical fibrosis and may produce symptoms commensurate with the normal function of the nerve involved, that is, balance or pain. BACKGROUND: Microscopic traumatic neuromas have been identified in postoperative middle and inner ear fibrosis in the temporal bones of patients complaining of intractable pain or imbalance. METHODS: Postsurgical temporal bones having inner or middle ear traumatic neuromas were reviewed. Of 20 bones with inner ear fibrosis after a variety of neurotologic surgeries, 12 were found to have traumatic neuromas, most from the utricular nerve or lateral canal. Five ears in 4 patients with middle ear fibrosis after chronic ear surgery had traumatic neuromas arising from Jacobson nerve. An additional 58 bones from chronic ear surgery patients with no neuromas served as a control group. Neurofilament immunohistochemistry labeling substantiated the presence of nerve fibers. Clinical symptoms noted from the clinical records were compared between those with and without traumatic neuromas. RESULTS: Of the 12 patients (75%), 9 with inner ear traumatic neuromas clinically reported constant disequilibrium postsurgery lasting for years. None (0%) without neuromas reported new symptoms postoperatively (p

Exertional headache as unusual presentation of the syndrome of an elongated styloid process.

We present the case of a 34-year-old man with a 2-year history of pain related to efforts in heavy lifting, beginning in the right ear and radiating to the neck and to the vertex. He underwent multiple negative neuroimaging examinations, until a 3-dimensional computerized tomography scan of the pharyngeal region evidenced an elongated styloid process. A diagnosis of Eagle's syndrome was made. The excision of the elongated styloid process was performed, resulting in complete and lasting pain relief. We focus on Eagle's syndrome and in particular on this atypical presentation.

Dor de ouvido e as percepções de agentes comunitários de saúde: entre o saber popular e as barreiras ao tratamento / Earache and the perception of health community agents: between the people knowledge and barriers to assistance

A otite é uma das morbidades infantis que repercute no desenvolvimento da linguagem, causando sintomatologia dolorosa. No âmbito da atenção primária à saúde, o Agente Comunitário de Saúde (ACS) atua como elo entre a equipe de saúde e a comunidade. Tendo por objetivo revelar a percepção dos ACS frente às dores de ouvido na zona rural de Monte Negro-RO, o método da pesquisa consistiu em entrevistas com 20 ACS. Utilizou-se a figura metodológica discurso do sujeito coletivo. A partir das respostas dos ACS, foram construídas as categorias: sofrimento, patologia, cuidado e desconhecimento. A percepção dos ACS diante da dor de ouvido constrói noções, que não são claras o bastante para se definirem como conceito. Sendo o relato subjetivo do usuário o principal instrumento para mensurar a dor, o encontro de subjetividades que se produz no relato do ACS se deve ao papel de sujeito que trabalha com as diversidades culturais em que está inserido. A compreensão de seu discurso implica a possibilidade de construção de um enfoque da atenção básica à saúde que leve em consideração o saber popular.

Otitis is an infantile morbiditie directly interfering in the language development process, causing painful symptoms. The Health Community Agent (HCA) acts as a link between the health team and the community. This work aimed at revealing the perception of HCA as for auditory pain, in rural communities of Monte Negro, RO, Brazil. The research method consisted of interviews with 20 HCA. The study was accomplished by the qualitative method, utilizing methodological figures, as Collective Subject Speech. Out of the HCA` answers, central ideas allowed the building of categories such as: suffering, pathology, care, unawareness. The HCAs perception of earache leads to notions which are not clear enough to be defined as a concept. Being the patients subjective report the main tool to measure pain, the subjectivities produced in the HCAs report owe to the role of the individual who works with the cultural diversities in which he/she is inserted. The understanding of his speech implies the possibility of building a focus to basic health attention, taking into account popular wisdom.

External auditory canal cholesteatoma: reassessment of and amendments to its categorization, pathogenesis, and treatment in 34 patients.

OBJECTIVE: External auditory canal cholesteatoma (EACC) is a rarity. Although there have been numerous case reports, there are only few systematic analyses of case series, and the pathogenesis of idiopathic EACC remains enigmatic. STUDY DESIGN: In a tertiary referral center for a population of 1.5 million inhabitants, 34 patients with 35 EACC (13 idiopathic [1 bilateral] and 22 secondary) who were treated between 1994 and 2006 were included in the study. RESULTS: EACC cardinal symptoms were longstanding otorrhea (65%) and dull otalgia (12%). Focal bone destruction in the external auditory canal with retained squamous debris and an intact tympanic membrane were characteristic. Only 27% of the patients showed conductive hearing loss exceeding 20 dB. Patients with idiopathic EACC had lesions typically located on the floor of the external auditory canal and were older, and the mean smoking intensity was also greater (p < 0.05) compared with patients with secondary EACC. The secondary lesions were assigned to categories (poststenotic [n = 6], postoperative [n = 6], and posttraumatic EACC [n = 4]) and rare categories (radiogenic [n = 2], postinflammatory [n = 1], and postobstructive EACC [n = 1]). In addition, we describe 2 patients with EACC secondary to the complete remission of a Langerhans cell histiocytosis of the external auditory canal. Thirty of 34 patients were treated surgically and became all free of recurrence, even after extensive disease. DISCUSSION: For the development of idiopathic EACC, repeated microtrauma (e.g., microtrauma resulting from cotton-tipped applicator abuse or from hearing aids) and diminished microcirculation (e.g., from smoking) might be risk factors. A location other than in the inferior portion of the external auditory canal indicates a secondary form of the disease, as in the case of 2 patients with atypically located EACC after years of complete remission of Langerhans cell histiocytosis, which we consider as a new posttumorous category and specific late complication of this rare disease.

Traumatic neuroma of the tympanic (Jacobson's) nerve as a possible cause of otalgia.

OBJECTIVE: To show that traumatic neuroma of the tympanic (Jacobson's) nerve may be a cause of recurrent intractable otalgia in patients following radical mastoidectomies. STUDY DESIGN: Histologic evaluation of four temporal bones from three patients with a history of recurrent otalgia following radical mastoidectomy. SUBJECTS AND METHODS: The medical records of three patients with multiple middle ear surgeries in four ears because of recurrent otalgia were reviewed. Histopathologic studies of the four temporal bones were performed. RESULTS: All four of the temporal bones that underwent multiple surgeries were found to have traumatic neuromas of the tympanic (Jacobson's) nerve. CONCLUSION: Recurrent otalgia in patients after radical middle ear surgery may be caused by a traumatic neuroma of the tympanic (Jacobson's) nerve.

Otite média aguda recorrente / Acute otitis Media

Os autores fazem uma revisão bibliográfica sobre a otite média recorrente (OMR), visto que a mesma é a doença mais comum na infância, depois do resfriado. Além disso, é uma das principais causas de atendimento em pediatria, causando muita dor e sofrimento às crianças e aos seus pais

[Predictive significance of reflex otalgia in local radical radiotherapy of oropharyngeal carcinomas]. / Prädiktive Bedeutung der Reflexotalgie in der lokal radikalen Radiotherapie von Oropharynxkarzinomen.

BACKGROUND: Patients with carcinomas of the upper aero-digestive tract often suffer from ear pain as a tumor associated syndrome. This prospective study examines the predictive and prognostic value of this symptom. PATIENTS AND METHODS: Ninety-six consecutive patients who completed a locally radiotherapy of a carcinoma of the oropharynx were prospectively evaluated and followed. Forty-nine out of 96 patients stated the symptom, either spontaneously or after questioning. The 2 groups showed no difference regarding TNM-classification, histology and total dose. Overall survival, local control and disease specific survival were calculated according to Kaplan-Meier and compared by the log-rank test. RESULTS: A clinically complete remission was obtained in significantly fewer patients with reflex-otalgia as compared to patients without reflex-otalgia, 61.2% versus 89.3%, p < 0.002. Local control of patients with reflex-otalgia was significantly less with 49%, mean follow-up 564 days, in comparison to local control in patients without reflex-otalgia, mean follow-up 613 days, p = 0.01. Disease specific survival was significantly worse for patients with reflex-otalgia, p < 0.012. The probability of local control of T1/T2 tumors with reflex-otalgia was similar to T3/T4 tumors without reflex-otalgia. Local control for all tumor categories combined is 74% for patients without reflex-otalgia versus 49% for patients with reflex-otalgia. CONCLUSION: In our patients, reflex-otalgia is a new and statistically significant parameter for the probability of local control and disease specific survival.

The pathophysiology of otitic hydrocephalus.

The pathophysiology of otitic hydrocephalus remains controversial. It has been argued that involvement of the superior sagittal sinus, by, at least, a mural thrombus is a necessary component of this disease. We present a case of otitic hydrocephalus where on magnetic resonance imaging (MRI) normal luminal and mural flow within the superior sagittal sinus is demonstrated. The presence of thrombus in the lateral venous sinus alone appears sufficient in this case to impede venous drainage of the intracranial contents into the neck and produce a rise in the cerebral venous pressure and a subsequent increase in the CSF pressure. The presence of a superior sagittal sinus mural thrombus is not required.
