Surgical management of deep lobe parotid tumours with and without involvement of the parapharyngeal space.

The diagnosis and treatment of deep lobe parotid tumours is challenging because of the complex surgical accessibility. There is a lack of studies describing the differences between deep lobe tumours that do and do not occupy the parapharyngeal space (PPS). Patients treated for deep lobe tumours occupying the PPS (PPS group) and not occupying the PPS (non-PPS group) were analysed retrospectively. A total of 227 patients were treated surgically for deep lobe parotid tumours between 1990 and 2019. Sixty patients (26.4%) presented with tumours that involved the PPS (PPS group), while 167 (73.6%) presented with tumours that did not occupy the PPS (non-PPS group). The majority of the PPS group tumours were removed using a transcervical or transcervical-transparotid approach. PPS group tumours were larger (P < 0.001), and tumour spill occurred more frequently in this group (benign tumours: P = 0.002; malignant tumours: P = 0.033). Complication rates did not differ between the PPS and non-PPS groups. A transcervical or transcervical-transparotid approach is the preferred method for the management of deep lobe parotid tumours that occupy the PPS in our practice. Tumour spill occurred more frequently in the PPS group, which is most probably due to the larger tumour size and more complex accessibility.

Development of the Drooling Infants and Preschoolers Scale (DRIPS) and reference charts for monitoring saliva control in children aged 0-4 years.

OBJECTIVES: To develop and validate a parent questionnaire to quantify drooling severity and frequency in young children (the Drooling Infants and Preschoolers Scale - the DRIPS). To investigate development of saliva control in typically developing young children in the age of 0-4 years. To construct sex-specific reference charts presenting percentile curves for drooling plotted for age to monitor the development of saliva control in infancy and preschool age. STUDY DESIGN: The DRIPS was developed consisting of 20 items to identify severity and frequency of drooling during meaningful daily activities. Factor analysis was performed to test construct validity. A piecewise logistic regression was followed by a piecewise linear regression to construct sex-specific reference charts. RESULTS: We obtained 652 completed questionnaires from parents of typically developing children. The factor analysis revealed four discriminating components: drooling during Activities, Feeding, Non nutritive sucking, and Sleep. To illustrate the development of saliva control, eight sex-specific reference curves were constructed to plot the scores of the DRIPS by age group, at the 15th, 50th, 85th and 97th percentile. About 3-15% of the preschoolers in our cohort did not acquire full saliva control at the age of 4 years. CONCLUSIONS: With the DRIPS it is possible to validly compare and visualize the development of saliva control in an individual infant or preschooler and allow clinicians to timely initiate individually targeted interventions if children outperform.

The efficacy of hyperbaric oxygen therapy related to the clinical stage of osteoradionecrosis of the mandible.

This study aimed to evaluate the success of hyperbaric oxygen therapy (HBOT) and surgery in the treatment of mandibular osteoradionecrosis (ORN) in relation to the extent of the ORN. Twenty-seven patients with ORN were identified from a total of 509 patients with a history of primary oral or base of the tongue cancer; these patients had been treated with radiation therapy with curative intent between 1992 and 2006, with a radiation dose to the mandible of ≥50Gy. The ORN was staged according to the classification of Notani et al. The time from completion of radiation therapy to the development of ORN varied (median 3 years). Forty HBOT sessions were offered. After HBOT alone, 3 of 11 stage I lesions, 0 of 8 stage II lesions, and 0 of 8 stage III lesions had healed (P=0.0018). An absolute incidence of 5.3% ORN was found in this population. Of all sites irradiated in this study, the floor of the mouth was most associated with ORN (8.6%), whereas the cheek was least associated (0%). Based on the results of this study, HBOT can be recommended for stage I and II ORN and for selected cases of stage III ORN.

Vocal fold hyalinosis in Urbach-Wiethe disease, a rare cause of hoarseness.

BACKGROUND: Lipoid proteinosis is an autosomal recessive disorder characterized by hyalin deposits in the skin and mucosa of the upper aerodigestive tract; currently, no treatment exists. Nearly all patients experience hoarseness and speech difficulties, due to hyalin deposition in the vocal folds and diminished mobility in infiltrated lips, tongue, and palate. METHODS: We describe a patient with extensive hyalin plaques on the vocal folds, which resulted in near-aphonic hoarseness. Hyalin deposits in the vocal folds and skin were treated with laser resection. RESULTS: Both the vocal folds and skin improved in appearance, with smoother surface epithelium. However, the patient's speech remained impaired, due to extensive hyalin plaques in the mouth, tongue, and lips. The voice improved only temporarily. CONCLUSIONS: Laser resection of hyalin plaques in the vocal folds and skin is a feasible treatment for lipoid proteinosis. However, speech may remain severely limited, due to impaired tongue and lip movement.

A congenital mucocele of the anterior dorsal tongue.

We report on a new-born with a congenital mucocele on the anterior dorsal side of the tongue. The presentation as well as the differential diagnosis of congenital oral swellings is discussed. Because of breastfeeding problems the mucinous swelling was incised and drained two days after birth. Immediately after drainage the swelling disappeared. Congenital oral swellings are rare. Most of them are mucoceles. Post-partum treatment is surgically, but spontaneous remission has been described. High incidence of recurrence should be taken into account when (micro-)marsupialization or incision as sole treatment is performed.

[A woman with an abnormality of the palate]. / Een vrouw met een afwijking op het palatum.

A 75-year-old woman was seen at the ENT department because of a bleeding tumor on the hard palate. The abnormality mimicked both clinically and histopathologically a malignant salivary gland tumor, but after excision it was diagnosed as necrotizing sialometaplasia. Clinicians should be aware of this rare and easily misdiagnosed benign disease, in order to avoid unnecessary treatment.

Interforaminal implant placement in oral cancer patients: during ablative surgery or delayed? A 5-year retrospective study.

In a retrospective study, two mandibular prosthetic rehabilitation strategies supported by implants in oral cancer patients were evaluated: implants placed in the non-resected edentulous symphyseal area during ablative surgery (DAS implants); or at a later stage (postponed (P) implants). Medical files of patients from two head-neck oncology groups from 2000 to 2005 were screened for study inclusion. DAS protocol was used in one group and P protocol in the other. After a 5 year follow-up of 261 edentulous patients with oral cancer in the second group, P implants were placed in 27 patients to support an overdenture. Of the 249 edentulous patients in the first group, 82 patients were given an implant supported overdenture using the DAS implant protocol. Regarding implant loss, no statistically significant differences were seen between the DAS and P implants. In the DAS group, more patients benefited from an implant-supported lower overdenture (39 versus 11%, respectively), and they received their overdenture on average 20.0 months sooner (sd=11.01, p<0.001) after ablative surgery. 17.1% of DAS implants and 4.6% of P implants were never loaded due to tumour and patient related factors including unfavourable implant soft tissue, tumour recurrence near the implant, or radiotherapy induced trismus.

Perioral gustatory sweating: case report.

OBJECTIVE: Presentation of a case of perioral Frey syndrome. DESIGN: Case report. SUBJECT: A 72-year-old woman with hyperhidrosis around the mouth and chin. RESULTS: This patient suffered from bilateral perioral gustatory sweating following a mandibular osteotomy; such a case has not previously been described. Possible pathophysiological hypotheses are discussed in relation to the anatomy and innervation of the salivary glands. CONCLUSION: Perioral gustatory sweating is a rare complication of osteotomy.

Diagnostic value of magnetic resonance lymphography in preoperative staging of clinically negative necks in squamous cell carcinoma of the oral cavity: a pilot study.

Pilot study evaluating the diagnostic value of magnetic resonance lymphography (MRL) compared with conventional imaging techniques in the preoperative staging of the clinically (palpable) negative neck (cN0) in squamous cell carcinoma of the oral cavity (SCCOC). Patients with SCCOC without clinical evidence of lymph node metastasis and scheduled for surgery underwent MRL in combination with ultrasound with or without fine needle aspiration cytology and multi-detector computer tomography. MRL images were interpreted by 2 independent radiologists. All patients were planned for resection of the primary tumor and a selective neck dissection of levels I-III. Histopathologic results were evaluated as the gold standard and compared with preoperative findings. One of nine evaluated patients had a metastatic node on histopathologic analysis. In all but 1 patient, MRL showed possible metastatic spread in at least 1 node. On a node-to-node basis, negative predictive value (NPV) and sensitivity reached 100% for 1.5- en 3Tesla (T) MRL, specificity reached 92% at 1.5T and 93% at 3T MRL, and positive predictive value (PPV) was 8% at 1.5T MRL, for both radiologists. PPV at 3T MRL was 10% and 9%, for radiologists I and II, respectively. This pilot study shows that MRL has a high NPV based on a node-to-node analysis. However, its PPV was only 10%, and therefore its use as a single imaging technique in the preoperative staging of the cN0 neck in SCCOC seems to be limited. Further studies are needed to confirm these data.

Airway obstruction due to inflammatory myofibroblastic tumour of the posterior pharyngeal wall.

OBJECTIVE: We report a unique case of inflammatory myofibroblastic tumour of the posterior wall of the hypopharynx. METHOD: We present the patient's case history, management and histopathological findings. A literature review of all cases localised to the larynx or pharynx is provided and discussed. RESULTS: A 67-year-old man presented with airway obstruction due to a spherical mass in the hypopharynx originating from the posterior pharyngeal wall. The tumour was resected. Histopathological examination revealed an inflammatory myofibroblastic tumour. We found only five previously reported cases with pharyngeal localisation. Further treatment of the patient is described. CONCLUSION: Inflammatory myofibroblastic tumour of the pharynx is extremely rare. It is regarded as a neoplastic tumour of intermediate biological potential. In cases with extrapulmonary localisation, the incidence of local recurrence can be as high as 25 per cent. Radical surgery is the treatment of choice; no adjuvant therapy is necessary.

Assessment of preoperative ultrasonography of the neck and elective neck dissection in patients with oral squamous cell carcinoma.

Estimating the value of our preoperative workup in the treatment of patients with clinically N0 (cN0) squamous cell carcinoma of the oral cavity. Retrospective analysis. Results of preoperative palpation, ultrasound (US) and ultrasound-guided fine needle aspiration cytology (FNAC) were compared to the histological findings after unilateral or bilateral elective selective neck dissection of level I-III (SND I-III) in patients with cN0 squamous cell carcinoma of the oral cavity. Occult metastases were detected by in 50 (22%) out of the 224 cN0 patients. No metastases were found beyond level III in extended neck dissections. T1N0M0 tumors and T2N0M0 tumors metastasized in 8 out of 77 cases (10%) and 32 out of 112 (29%) cases, respectively. Staging of the cN0 neck by palpation and US (+/-ultrasound-guided FNAC) missed occult lymph node metastases in 22% of the patients with oral cavity squamous cell carcinoma. The use of SND I-III therefore still is warranted. Frozen section sampling seemed to be redundant in this selected group of patients, because no additional metastases were found in extended neck dissection specimens. It might not be necessary to perform elective neck dissection in patients with T1 tumors.

Acute upper airway failure and mediastinal emphysema following a wire-guided percutaneous cricothyrotomy in a patient with severe maxillofacial trauma.

BACKGROUND: In the presence of severe maxillofacial trauma, management of the airway is important because this condition poses a significant threat to airway patency. That securing the airway is not always straightforward is described and illustrated in this paper. CASE: We present the case of a 23-year-old patient who sustained severe maxillofacial injury for which airway control was necessary. A wire-guided percutaneous dilation cricothyrotomy was performed, which was most probably the cause of an acute loss of airway patency. The literature regarding the role of percutaneous techniques in an elective and emergency setting is reviewed.

A 17-year-old girl had a persistent ulcerating external submandibular fistula which radiographically originated from a periapical abscess of the left lower second molar.

Effect of postoperative radiotherapy on the functional result of implants placed during ablative surgery for oral cancer.

The purpose of this retrospective study was to evaluate the survival of dental implants placed during ablative surgery in the interforaminal region of the original edentulous mandible in patients with squamous cell carcinoma of the oral cavity in relation to postoperative radiotherapy. Forty-eight patients treated in 1996-2003 with surgery alone or in combination with postoperative radiotherapy were analysed. In all patients, 2 to 4 Brånemark Mk II/III 2-phase implants were placed during tumour resection. A total of 139 implants were placed of which 61 (21 patients) received postoperative radiotherapy: 60-68 Gy as a boost dose on the primary tumour site and 10-68 Gy on the symphyseal area. No difference was found in percentage of functional dentures on implants between the radiated and non-radiated groups. The success rate of osseointegration was 97% in the postoperative irradiated group and 100% in the non-irradiated group. The prosthetic success rate (75%) was lower because in 12 of the 48 patients (34 implants) a functional denture could not be fitted due to tumour recurrence or metastasis (7 patients, 22 implants) or for psychological reasons (4 patients, 12 implants), independent of whether radiotherapy was administered. Postoperative radiotherapy does not affect the osseointegration of dental implants placed during tumour ablation and the ultimate number of functional dentures. Primary implant placement in edentulous mandibles may have advantages over secondary implant placement in patients with oral squamous cell carcinoma.

[Rendu-Osler-Weber disease]. / De ziekte van Rendu-Osler-Weber.

Rendu-Osler-Weber disease or hereditary hemorrhagic telangiectasia (HHT) is a multisystem autosomal dominant hereditary disorder. The disorder is manifested by multiple dysplasia of blood vessels of the skin and mucous membranes. This results in recurrent and sometimes severe bleeding, of which epistaxis is the most common. Cardial, pulmonary and cerebral manifestations can be responsible for complications. A patient is presented with Rendu-Osler-Weber disease followed by a review of literature.

Compliance, quality of life and quantitative voice quality aspects of hands-free speech.

CONCLUSIONS: With the use of a new automatic stoma valve (ASV) it appears possible to rehabilitate patients who have previously been unsuccessful in acquiring hands-free speech. As well as making daily ASV use possible for an additional group of patients, this new device was also appreciated by many patients as an additional rehabilitation tool for specific occasions. Despite statistically significant improvements in aspects of voice and breathing using this novel ASV, improvement of peristomal adhesion is probably the main factor needed to further increase success rates. Nevertheless, our results show that it makes sense to keep trying to achieve hands-free speech, even if previous attempts have failed. OBJECTIVE: To make a long-term (6 months) assessment of compliance and aspects of voice, breathing and quality of life using a new ASV: the Provox FreeHands heat and moisture exchanger (HME). MATERIAL AND METHODS: This was a prospective clinical multicentre trial in 79 laryngectomized patients (8 regular ASV users, 58 previously unsuccessful users and 13 new users). Data were collected at baseline and after 1 and 6 months by means of European Organization for Research and Treatment of Cancer Quality of Life questionnaires and specific structured questionnaires concerning compliance, skin adhesion, voicing and pulmonary aspects. An objective assessment of voice parameters (maximum phonation time, maximum phonation time while counting, dynamic loudness range and number of pauses in a standard read-aloud text) was made for comparison of different stoma occlusion methods (digital occlusion via an HME and two different ASVs). A subjective assessment of overall voice quality was made. RESULTS: After 6 months, 19% of patients used the new ASV on a daily basis (mean 5 h/day), while 57% used it on an irregular basis as an additional rehabilitation tool for special occasions. Two-thirds of the study group indicated that they would continue to use the new ASV after the study period. With respect to the objective parameters, statistically significantly better maximum phonation times and dynamic loudness ranges were observed with the new ASV compared to the Blom-Singer ASV. However, the best results for all the objective parameters were obtained with digital occlusion via the Provox HME.
