Clinical impact of ectopic teeth in the maxillary sinus.

OBJECTIVE: To evaluate the clinical features, aetiologic factors, challenging properties (such as radio opacity in Water's view in a patient with no sinusitis), signs and symptoms of the ectopic teeth in the maxillary sinus. STUDY DESIGN: Clinical symptoms and radiographic findings of 14 patients with ectopic teeth in the maxillary sinus were evaluated. Computed tomography (CT) and conventional radiographic images of maxillary sinus and clinical findings were compared with each other with regard to the final diagnosis. RESULTS: Water's view is inadequate to diagnose ectopic tooth in the maxillary sinus in some cases. Panoramic radiographs may be preferred before CT to evaluate the ectopic tooth in the maxillary sinus as structure of a tooth can be clearly detected on panoramic radiographs. Crowding was the most common aetiologic factor among the 14 cases. CONCLUSION AND SIGNIFICANCE: The patients with ectopic tooth in the maxillary sinus should be evaluated thoroughly by complete otorhinolaryngologic, intraoral examinations and proper diagnostic imaging procedures in order to avoid misdiagnosis of maxillary sinusitis. As the opacity of the maxillary sinus in Water's view due to ectopic tooth can be misinterpreted as maxillary sinusitis, patients who have sinusitis-like complaints and opacity of maxillary sinus in Water's view who are resistant to medical treatment should be evaluated with respect to the presence of ectopic tooth.

Choanal polyp originating from the inferior turbinate presenting as nasal polyposis.

Although choanal polyps frequently arise from the maxillary sinus, a choanal polyp originating from the inferior turbinate is a rare entity. A 14-year-old girl who had a history of bilateral nasal obstruction with snoring, mouth breathing and nasal discharge for 10 years was presented. On endoscopic examination, a polypoid mass completely obliterated the right nasal cavity. The left choana was also totally occluded by the polypoid mass. Endoscopic polypectomy was performed and it was observed that the polyp originated from the right inferior turbinate. Choanal polyps arising from the inferior turbinate should be kept in mind in the differential diagnosis of unilateral nasal polypoid masses.

Incidence of unexpected pathology in routine adenoidectomy specimens.

OBJECTIVE: The aim of this study was to determine the incidence of unexpected pathologies in adenoidectomy specimens and necessity for histopathologic evaluation of adenoid tissue. MATERIALS AND METHODS: All patients younger than 16 years who underwent routine adenoidectomy were reviewed. Patients were excluded if the primary surgery was other than routine adenoidectomy such as nasopharyngeal biopsy for suspicion of malignancy or other pathology. RESULTS: One thousand one hundred eighty-four patients (683 males, 501 females) were involved in this study. The mean age was 7.53+/-3.24 years, ranging between 2 and 16 years. There was no patient with unexpected pathology among 1184 routine and primary adenoidectomy procedures. However, one patient had unexpected pathology among 33 revision adenoidectomy procedures (3%). CONCLUSIONS: There was no occult pathology in routine primary adenoidectomy. The incidence of unexpected pathology in revision adenoidectomy was 3%. Microscopic evaluation of adenoid tissue gives some knowledge about histological properties and rarely some unexpected pathologies. Searching for malignancy is unnecessary in routine primary adenoidectomy cases without any other clinical, radiological and laboratory findings.

What is the relationship between chronic sinus disease and isolated nasal septal deviation?

OBJECTIVE: The aim of this retrospective study is to examine the role of isolated nasal septal deviation (NSD) in the pathogenesis of chronic rhinosinusitis (CRS). STUDY DESIGN AND SETTING: The interaction between isolated NSD and chronic sinus disease were retrospectively evaluated in 1452 patients. Out of 1452 patients, 152 patients were included in the study. Patients with anatomical variants other than NSD were excluded from the study. Patients with NSD were enrolled in the study group and patients without NSD were enrolled in the control group. RESULTS: There was no statistically significant difference between NSD group and non-NSD group with respect to the CRS. CONCLUSIONS: The mild to moderate degree of NSD was not a risk factor for chronic sinus disease. Only gross deviation of the nasal septum itself is a risk factor for the development of CRS. SIGNIFICANCE: Excluding the subjects with ostiomeatal anatomic variations has differentiated this study from the previously reported researches (isolated NSD).

Squamous cell metaplasia of the nasopharyngeal epithelium and its association with adult-onset otitis media with effusion.

CONCLUSION: The common association between adult-onset otitis media with effusion (AO-OME) and squamous cell metaplasia (SCM) of the epithelium of Rosenmüller's fossa, which is near the Eustachian tube orifice, implies the predictive role of metaplasia, which probably compromises the drainage function of the middle ear. OBJECTIVE: To determine the effects of nasopharyngeal epithelial changes (SCM) on AO-OME. AO-OME is a multifactorial and insidious disease that may necessitate detailed investigation, i.e. biopsy of the nasopharynx, because of possible underlying nasopharyngeal malignancy. MATERIAL AND METHODS: Fifty-two patients with AO-OME (study group) and 29 with a unilateral neck mass in the posterior triangle without AO-OME (control group) were enrolled. Nasopharyngeal biopsies taken from all subjects were evaluated with regard to surface epithelial changes of the nasopharynx. RESULTS: Nasopharyngeal biopsies revealed SCM in 34/52 patients (65%) in the study group and 9/29 (31%) in the control group (p<0.05). During the follow-up period, recurrence of effusion occurred in 56% of the group with SCM and 22% of the group without it.

[Toxoplasmosis in patients with lymphoid hyperplasia of the head and neck].

OBJECTIVES: To investigate the incidence of toxoplasmosis in patients with lymphoid hyperplasia of the head and neck. PATIENTS AND METHODS: In this study, 53 patients (32 males, 21 females; mean age 11.2+/-4.3 years, range 5 to 22) were investigated. There were hypertrophic tonsillitis in 13 patients, hypertrophic tonsillitis and adenoid hyperplasia in 22 patients, adenoid hyperplasia in 10 patients, and lymphadenopathy of the neck in eight patients. In venous blood samples, IgM and IgG antibodies for Toxoplasma gondii were investigated with the enzyme-linked immunoabsorbent assay (Axsym, Abbott). RESULTS: Positive IgG was determined in 23 patients (48%) with hypertrophic tonsillitis (n=6), hypertrophic tonsillitis and adenoid hyperplasia (n=10), adenoid hyperplasia (n=3), and lymphadenopathy of the neck (n=4). Positive IgM was determined in 5 patients (9.4%) with hypertrophic tonsillitis (n=1), hypertrophic tonsillitis and adenoid hyperplasia (n=1), and lymphadenopathy of the neck (n=3). CONCLUSION: Toxoplasmosis, which is known to cause lymphadenopathy, may be a reason for lymphadenopathy of the neck. Toxoplasmosis should be considered in the differential diagnosis of untreated patients with tonsillitis, adenoid hyperplasia, and chronic neck lymphadenopathy.

Congenital vomeral bone defect in two thalassemia trait cases.

The nasal septum is composed of a perpendicular plate of ethmoid bone, quadrilateral septal cartilage, membraneous septum, crest of palatine and maxillary bone and vomer. Defects of the nasal septum may be due to a variety of causes such as trauma, infection, inhalant irritants and neoplasia. To our knowledge, up until now, congenital defect of the vomer has been presented in six cases without any nasal symptoms. We present two cases of congenital defect of vomer with thalassemia trait, the patients complaining of nasal obstruction.

The correlation between septal deviation and concha bullosa.

OBJECTIVES: To investigate the incidence of concha bullosa (CB) in patients with septal deviation and the correlation between the angle of deviation and degree of pneumatization. Study and design This study was designed as a prospective trial. METHODS: Computerized tomography scans of the paranasal sinuses of 100 consecutive patients with the chief complaint of nasal obstruction and the diagnosis of septal deviation were taken. CB, sinus diseases, and septal deviation angles were recorded. RESULTS: Angles of deviation ranged between 3 and 25 degrees (mean, 13.0 +/- 4.1 degrees). The mean of angle of deviation in cases with CB and in cases without CB was 13.0 +/- 4.0 and 13.0 +/- 4.2 degrees, respectively. No statistical difference was found between them (P > 0.05). Pneumatization of the contralateral CB was statistically significantly higher than that of ipsilateral CB (P < 0.05). CONCLUSION: Septal deviation does not appear to give rise to the formation of CB, but augments the pneumatization of the middle turbinate depending on the degree of deviation angle.

Subjective pulsatile tinnitus associated with extensive pneumatization of temporal bone.

Pulsatile tinnitus (PT) although an infrequent otologic symptom. PT can be objective (auscaltable) or subjective (non-auscultable). It has been suggested that subjective PT could occasionally be associated with vascular disorders such as arteriovenous malformation, traumatic or spontaneous carotico-cavernous fistula, intracranial aneurysms, vascular tumors of the temporal bone and cerebellopontine angle, fibromuscular dysplasia, cervical venous hums and high jugular bulb. To our literature knowledge, it has not been reported subjective PT due to extensive pneumatization of temporal bone around internal carotid artery (ICA). In this report, we present a case of subjective PT, which was caused by resonance due to extensive pneumatization of temporal bone particularly peripheral to the ICA.

Otogenic pneumocephalus management with butyl 2-cyanoacrylate.

The existence of air within the skull has been called pneumocephalus. Treatment of pneumocephalus is mostly managed surgically, especially in a tension pneumocaephalus when the pressure has to be alleviated. Dural defect can be treated with the suture technique and tissue adhesives such as butyl 2-cyanoacrylate (B 2-CA). Otogenic pneumocephalus due to dural defect can be managed with B 2-CA tissue adhesive cheap, safely, and effectively without complication. We thought it would be of interest to present a case of pneumocephalus due to traffic accident 12 years ago and managed with B 2-CA. It is concluded that B 2-CA fixation can be alternative for dural defect closure with suturing or other tissue adhesives.

A case of orbital emphysema associated with internal laryngocele.

Orbital emphysema (OE) is usually the result of a fracture of lamina papyrecea or maxillary roof allowing air to pass from the sinuses into the orbit. OE without evidence of any significant trauma is a rare occurrence. Thorough literature search revealed that no case of OE due to the rupture of internal laryngocele has been reported. A case is reported here of bilateral orbitopalpebral emphysema associated with internal laryngocele, in the absence of facial skeleton trauma, in a healthy young adult male. It should be kept in mind that laryngocele rupture would be one of the underlying causes of OE or OE would be the presenting symptom of laryngocele rupture.

Multiple huge osteomas of the mandible causing disfigurement related with Gardner's syndrome: case report.

As osteomas of the bones including the jaws may be the initial symptom or clinical finding in the Gardner's syndrome, this entity should always be included in the differential diagnosis. A 20-year-old boy was referred to our clinic from another medical center. Extra-oral examination of the patient revealed an obvious asymmetry and disfigurement of the left mandibular corpus, angle and ramus. A panoramic radiograph revealed two huge osteomas at the angle, ramus and two smaller osteomas at the inferior border of the mandible. At the same time, there were an impacted canine and premolar. Diffuse sclerosis of the whole mandible was also seen. Upon the suspicion of Gardner's syndrome, barium passage radiographs of the intestine were requested and multiple polyps were observed. All of these findings led us to the diagnosis of Gardner's syndrome. The oral and maxillofacial surgeon and the dentist needs to be aware of the components of this entity because manifestations in the head and neck including epidermoid cysts, osteomas, odontomas, exostoses, supernumerary and impacted teeth are common. At the same time, osteomas causing disfigurement on the face related with Gardner's syndrome with increased uptake in scintigraphic examination should be treated by surgical excision of the lesions.

[The beneficial effect of septoplasty on snoring].

OBJECTIVES: This study sought to determine whether septoplasty played a favorable role on snoring complaints as well. PATIENTS AND METHODS: The study included 56 patients (40 males, 16 females; mean age 40 years; range 21 to 60 years) who underwent septoplasty operation for causes other than snoring. The patients' snoring complaints were evaluated and rated before and three months after surgery. RESULTS: Before surgery, 22 patients were found to have complaints of snoring. The snoring complaints improved after septoplasty in 16 patients (72.7%). The decrease in snoring complaints was found statistically significant (p<0.01). CONCLUSION: Improvement in snoring complaints in patients undergoing septoplasty operation emphasizes the need for investigating and treating septum deviations which are a primary cause of upper respiratory tract obstruction.

Correlation between blood group and noise-induced hearing loss.

OBJECTIVE: To investigate the correlation between blood group and noise-induced hearing loss (NIHL). MATERIAL AND METHODS: The study was conducted in 176 factory workers who had been exposed to a noise level of 85-90 dB for 8 h a day for a period of > or = 10 years. Pure-tone audiometric measurements were performed in a standard silent room. The blood groups of the workers were obtained from the factory files. RESULTS: NIHL was found in 23 (32.0%), 35 (58.3%), 10 (38.5%) and 7 (38.9%) persons with blood groups A, O, B and AB, respectively. NIHL was determined to be significantly more frequent in workers with blood group O. CONCLUSION: We suggest that people with blood group O are more prone to develop NIHL.
