Long-term effects of parotidectomy.

The present study investigated the long-term complications of parotidectomy, the differences in these complications in regard to the pathological diagnosis and type of surgery. The patients were questioned regarding the presence of facial paresis-paralysis, pain, loss of sensation, scarring, collapse, and mouth dryness in the area of operation. Complaints of pain (p = 0.287), scarring (p = 0.456), and mouth dryness (p = 0.136) did not show statistically significant differences between the cases with benign or malignant pathological outcomes. However, complaints of loss of sensation (p < 0.001), collapse in the area of operation (p = 0.025), paresis-paralysis (p < 0.001), and fear of repeated surgery (p = 0.032) were present at significantly higher rates. Complaints of pain (p = 0.258), scarring (p = 0.665), mouth dryness (p = 0.113) and fear of repeated surgery (p = 0.053) did not show statistically significant differences between the cases who underwent superficial or total parotidectomy. However, complaints of loss of sensation (p = 0.002), paresis (p < 0.001), and collapse in the area of operation (p = 0.019) were present at significantly higher rates. The type of tumor and surgical approach significantly affect the quality of life; however, parotidectomy generally does not lead to serious long-term complications that would disturb the patients.

Long-Term Results of Partial Laryngectomized Patients.

AIM: This study was to present long-term oncological results, as well as the variables, that can increase nodal metastasis and reduce survival in patients diagnosed in the early and late stages of laryngeal cancer. METHODS: A total of 85 patients were included in the study. These patients were grouped as supracricoid partial laryngectomy (PL), supraglottic horizontal PL, and vertical frontolateral PL. Furthermore, at least 3 years of the long-term outcomes of the patients in these 3 groups were compared. RESULTS: Twenty-two of the patients (26%) had nodal metastasis, 16 (72%) of these patients were in Group I (P = 0.017); 14 patients (51%) had preepiglottic space (P = 0.075); 12 patients (50%) had paraglottic space involvement (P = 0.002); 9 (45%) patients with nodal metastasis had a depth of invasion more than 20 mm (P < 0.001). Out of the 16 patients who had positive intraoperative surgery margins, 5 (18%) of them had nodal metastasis (P = 0.589) and 14 (16%) patients were positive for perineural invasion, 3 (19%) of these patients had lymph node involvement (P = 0.074). One (5%) patient died with nodal metastasis. Median survival rate of all the patients was 44 ±â€Š0.836 (42.36-45.63) months and the overall survival rate was 92.9%. CONCLUSIONS: Paraglottic space involvement and tumor invasion depth were statistically effective on increased nodal metastasis. However, we suggest that depth of invasion may not be effective alone as a prognostic factor. In contrast to the known effect on overall survival was less lymph node.

The effect of radiotherapy on mucociliary clearance in patients with laryngeal and nasopharyngeal cancer.

The present study aimed to demonstrate how the nasal mucociliary transport times are affected in the patients receiving radiotherapy for head-neck tumor in two different anatomic localizations. The study included 44 patients receiving radiotherapy under the diagnoses of the nasopharyngeal and laryngeal cancer. The mucociliary transport times of both groups were measured via saccharine tablets before radiotherapy, and at months 3 and 6 after radiotherapy. The difference between the groups was statistically evaluated. The pre-irradiation (pre-RT) mean transport times of NPC and LC patients were 9.7 and 9.1 min, respectively. The difference in the mucociliary transport times between these two groups was not statistically significant (p = 0.49). The mean transport time was 26.1 min at post-RT month 3, 23.9 min, at month 6; the change from pre-RT to month 3 was significant (p < 0.05) and the change from month 3 to 6 was not statistically significant (p = 0.182). The mean transport time of the LC patients was 16.8 min. At post-RT month 3, 12.4 min. at month 6; the change from pre-RT to month 3 (p < 0.05) and the change from month 3 to 6 were statistically significant (p = 0.007). It was found that radiotherapy affected the physiological conditions of the patients with nasopharyngeal cancer in a more severe and sustained way compared to the LC patients, which negatively affects the patient's response to the treatment by the resulting organic and psychological effects.

Effect of the Rhinoplasty Technique and Lateral Osteotomy on Periorbital Edema and Ecchymosis.

AIM: The present study aimed to compare edema and ecchymosis in the early and late postoperative periods following the application of different surgical techniques (open and endonasal) and different types of lateral osteotomy (internal and external). METHODS: The files and photographs of a total of 120 patients whose records were regularly maintained/updated and who underwent septorhinoplasty operation with the same surgeon were retrospectively evaluated. Sixty-nine (57.5%) patients were women and 51 (43.5%) were men. The patients were divided into 4 different groups according to the operations they underwent as follows--Group I: open technique septorhinoplasty + internal/continuous lateral osteotomy; Group II: endonasal rhinoplasty + internal/continuous lateral osteotomy; Group III: open technique septorhinoplasty + external/perforating lateral osteotomy; and Group IV: endonasal rhinoplasty + external/perforating lateral osteotomy. Postoperative edema and ecchymosis, and lateral nasal wall mucosal damage because of osteotomy were evaluated. RESULTS: Postoperative second day edema and ecchymosis scores were statistically significantly better in patients in Group II compared with the patients in Group I (P = 0.010 and P = 0.004, respectively). Postoperative first day edema and postoperative seventh day ecchymosis scores were statistically significantly better in the patients in Group IV compared with the patients in Group III (P = 0.025 and P = 0.011, respectively). Intraoperative bleeding was similar in all groups. The nasal tip was more flexible in patients who underwent closed technique rhinoplasty. Unilateral mucosal damage occurred in 3 patients (4%) with internal lateral osteotomy, whereas no mucosal damage was present in patients with external osteotomy. CONCLUSIONS: The difference in the rate of edema and ecchymosis in the early postoperative period between the closed technique rhinoplasty and the open surgical approach was statistically significant, whereas osteotomy did not cause a significant difference. According to these results, the authors suggest endonasal surgery to prevent the development of edema and ecchymosis, whereas the choice of lateral osteotomy should be dependent on the experience of the surgeon.

Surgical anatomy of facial nerve for revision transmastoid surgery.

We analyze the relationships of the 3 segments of the facial nerve with respect to constant anatomic structures that can be identified during revision surgery via translabyrinthine approach. This study was conducted on 15 formalin-fixed cadavers whose facial nerves were dissected bilaterally under operative microscope via translabyrinthine approach. The distances between the round window niche and the midpoint of the tympanic segment and the beginning of the mastoid segment were 6.64 ± 1.79 mm and 3.99 ± 0.79 mm, respectively. The distances between the tympanic ostium of the eustachian tube and the first and the second genu were 7.02 ± 0.62 mm and 12.25 ± 1.24 mm, respectively. We used the superior semicircular canal, the tympanic ostium of the eustachian tube, and the round window niche as landmarks to identify the facial nerve during revision surgery. Our study also showed that the auricular branch may also be originated from the posterior surface of the facial nerve.

Nonmelanoma facial skin carcinomas: methods of treatment.

AIM: The objective was to present in this study the administered treatment, reconstruction, and outcomes for lesions excised according to a prediagnosis of facial tumor, whose pathological finding was reported as nonmelanoma skin tumor. METHODS: A total of 178 patients with full medical histories who were operated on for skin tumors in the Ear, Nose, and Throat Clinic of Ankara Oncology Education and Research Hospital between February 2010 and March 2012 were evaluated retrospectively. The test group was made up of 125 men (70%) and 53 women (30%), with a median age of 56 years (range, 29-89 years). RESULTS: Basal cell carcinoma was diagnosed in 112 patients (63%), 45 (40%) of whom underwent flap reconstruction procedures; squamous cell carcinoma (SCC) was diagnosed in 55 patients (31%), 25 (45%) of whom underwent flap reconstruction procedures; 5 patients (3%) were diagnosed with basosquamous carcinoma, 3 (60%) of whom underwent flap reconstruction, and metatypical carcinoma was found in 6 patients (3%), and 5 (80%) underwent flap reconstruction treatment. Recurrence occurred in 10 (18%) of the 55 SCC patients. Invasion depths in the patients with recurrence were between 7 and 30 mm. In 21 (46%) of the 45 patients without recurrence, invasion depths were between 4 and 30 mm, whereas the invasion depths in the other 24 patients (53.3%) were less than 4 mm. CONCLUSIONS: Metastatic lymph node involvement localized to the auricular, infra-auricular, and postauricular was present in the pathological specimens of all patients with lesions who had selective neck dissection I to IV included into their treatment. The depth of invasion of SCCs was found to be statistically significant in terms of recurrences.

Giant ethmoid osteoma originated from the lamina papyracea.

INTRODUCTION: Osteomas are slow- growing, benign tumors. They are the most common neoplasms of the paranasal sinuses. They are usually originates from the frontal and ethmoid sinus and much less frequently seen in the maxillary and sphenoid sinuses. Although the lamina papyracea is a part of ethmoid bone, a giant osteoma originated from the lamina papyracea is very uncommon. An osteoma of the paranasal sinus is usually asymptomatic. Headache, proptosis, epiphora, diplopia, dizziness, facial deformity, face pain and cerebral complications are possible symptoms. The treatment of the paranasal osteomas are controversial. CASE REPORT: A 65 year old patient that applied with stuffiness and headache to our clinic. She has had a smooth mass in the right nasal cavity. Paranasal sinus tomography showed an osseous lesion, the size of 4x 3 cm, arising from the right lamina papyracea. The mass excised endoscopically and reported as osteoma histopathologically. There was no complication. After 9 months, there was no recurrence. CONCLUSION: Giant osteomas of paranasal sinuses, especially originated from the lamina papyracea are rare. They can be treated successfully by endoscopic approaches without any recurrence and complication despite its size.

[Provox 2 use for voice restoration after total laryngectomy]. / Total larenjektomi sonrasi ses restorasyonu için provox 2 kullanimi

OBJECTIVES: This study aims to determine the problems of patients applied provox 2 voice prosthesis for speech rehabilitation with their prosthesis and our treatment modalities to increase the quality of life of these patients. PATIENTS AND METHODS: A total of 210 patients (180 males, 30 females; mean age 58±11.9 years; range 37 to 83 years) who underwent total laryngectomy, applied and changed provox 2 voice prosthesis for voice restoration were included in the study. For speech restoration of the patients with a primary (intraoperative) and secondary (postoperative) tracheoesophageal fistula was opened. In the 15th postoperative day, provox 2 voice prosthesis was placed to approximately 0.5 cm inferior and midline fistula line of the tracheostoma. The patients underwent speech exercises. RESULTS: The mean change time of prosthesis was 7.5 months (range 1 to 48 months). Fungal colonization was detected in 141 patients (66%) who had voice prostheses. Granulation tissue developed around the voice prosthesis in 30 patients (14%), three patients (1%) swallowed their voice prosthesis, tracheoesophageal fistula width remained permanently in two patients (1%), and these patients were abandoned to use their voice prosthesis. Mediastinitis occurred in one patient (1%). CONCLUSION: Due to several reasons such as success of high speech despite of complications and being easy to fight with these complications, provox voice prosthesis is an effective method to use for voice restoration.

Analysis of multicentricity in supraglottic laryngeal carcinoma treated with partial laryngeal surgery.

A clinicopathological analysis of multicentricity in patients treated with either supraglottic horizontal laryngectomy or supracricoid partial laryngectomy for supraglottic squamous cell carcinoma of the larynx was conducted. This study included 63 patients who underwent supracricoid partial laryngectomy or supraglottic horizontal laryngectomy for T2 or T3 supraglottic laryngeal squamous cell carcinoma. The patients were divided into two groups: Group 1 included patients with one focus of the tumor (monocentric), and Group 2 included patients who had more than one focus of the tumor (multicentric) diagnosed after pathology examination. Forty-eight (76.2 %) of the patients had one focus of the tumor (Group 1) and 15 (23.8 %) of the patients had more than one focus of the tumor (Group 2). The rates of lymph node metastasis in Group 1 and Group 2 were 12.5 and 60 %, respectively. The second focus was invasive in seven (46.6 %) of the patients, carcinoma in situ in six (40 %) of the patients, and both invasive and carcinoma in situ in two (13.3 %) patients. The overall 3- and 5-year survival rates of Groups 1 and 2 were 77.1-66.7 % and 56.2-46.7 %, respectively. With regard to survival rates, no statistically significant difference was observed between Group 1 and Group 2 (p = 0.576). The lack of statistical significance might have been associated with the low sample size. Although multicentric tumors of the supraglottic larynx have high incidence of nodal metastasis, no significant increase in the rate of recurrence was determined.

[The correlation of positron emission tomography-computed tomography assessment with histopathological results in the diagnosis of head and neck cancer of unknown primary]. / Primeri bilinmeyen bas boyun kanserleri tanisinda pozitron emisyon tomografi-bilgisayarli tomografi incelemesinin histopatolojik sonuçlar ile iliskisi.

OBJECTIVES: This study aims to evaluate the extent of the correlation between positron emission tomography-computed tomography (PET-CT) and histopathological and/or cytological evaluations in demonstrating malignancy and identifying the primary in patients with head and neck tumors of unknown primary. PATIENTS AND METHODS: The excision records and files of 32 patients (24 males and 8 females; mean age 54.2 years; range 24 to 75 years) with previous PET-CT evaluations performed due to a mass with an unknown origin and to identify the primary were retrospectively analyzed. Positron emission tomography-computed tomography results and neck dissection (ND) materials were compared and PET-CT's ability to provide localization of the primer was determined by standardizing the study data. RESULTS: In respect of determining primary localization, PET-CT's sensitivity was determined as 66.6%, its specificity as 33.3%, its positive predictive value as 80%, and its negative predictive value as 20%. When the neck dissection specimens were considered according to the different regions they were obtained from: PET-CT's specificity was determined as 63.6%, its sensitivity as 94.5%, its positive predictive value as 87.5%, and its negative predictive value as 58.1%. CONCLUSION: Positron emission tomography-computed tomography sensitivity in determine the regions with pathologic lymph node involvement according to the BD specimen results and positive predictive value in identifying primary localization was found to be in accordance with the literature. Based on these results, PET-CT is a valuable method for early diagnosis and treatment in difficult cases.

Anatomic basis of percutaneous Kirschner wire insertion in zygoma fractures.

The combination of Gillies elevation with 1-point percutaneous Kirschner wire fixation of isolated simple zygoma fractures was found to be effective in restoring preinjury appearance and function and avoiding soft tissue morbidity. The proximity of the infraorbital nerve, inferior orbital rim, and dental roots warrants care in the placement of the wire. The need for precise anatomic guidelines becomes apparent when considering these relationships. Eighteen adult skulls (36 sides) were examined, and specific points were determined that could be important while inserting Kirschner wire for zygoma fractures, and the distances between those points were measured with a digital caliper. Then, by using these points, the wire was inserted into the zygoma through the medial wall of the maxillary sinus, and the insertion point of the wire on the lateral wall of the maxilla and the angle of the wire were determined. The mean lengths of the wires of the right and left sides of each skull were counted, and for 18 skulls, the mean length of the wire was measured as 45.12 mm. Direction of the insertion during drilling zygoma, conversely to the location of the insertion, nearly determines the course of the wire and the point of insertion on the lateral wall of the maxilla. Obtaining precise information concerning the installation angle and length of the wire before surgery should contribute to safer and smoother surgical procedures.

Can the Müller maneuver detect multilevel obstruction of the upper airway in patients with obstructive sleep apnea syndrome?

OBJECTIVES: Our aim is to figure out the role of Müller maneuver (MM) to detect the level of upper airway obstruction and the severity of obstructive sleep apnea syndrome (OSAS). PATIENTS AND METHODS: In this study, polysomnographies were made after the routine otorhinolaryngological examination including MM in patients admitted with OSAS suspicion in Ankara Oncology Training and Research Hospital's Department of Otorhinolaryngology, Sleep Medicine Policlinic. Two-hundred and twenty-one OSAS patients (142 males, 179 females; mean age 47.63 years; range 18 to 82 years) were included to the study. RESULTS: There weren't any significant correlation among apnea hypopnea index (AHI) results and body mass index (BMI), tonsil size and obstruction severity due to MM (p>0.05). Müller maneuver scores are positively correlated to the Epworth sleepiness scale (EPSS) scores (r=0.213 and p<0.001). Epworth sleepiness scale scores are found to be correlated to BMI and neck circumference (p<0.05). Level of the airway obstruction doesn't affects the EPSS scores (p=0.235). Also EPSS scores are not affected from uni or multilevel obstruction (p=0.088). CONCLUSION: The severity of the MM score is not correlated to the severity of OSAS according to AHI results, but it is found to be correlated to EPSS. Vibrating tissues caused local and systemic inflammation in OSAS patients. The correlation between EPSS and MM scores can be explained by this inflammatory process. Further prospective studies have to be done in this field. Müller maneuver in an awake patient might reflect the levels of the obstruction in sleep conditions even though insufficient for figuring out the severity of OSAS.

[Management of recurrent lower lip carcinomas]. / Nüks alt dudak kanserlerine yaklasim.

OBJECTIVES: In this study patients who had locoregional recurrence of lower lip carcinomas after therapies such as surgery, electrocoagulation, cryotherapy or traditional local therapies are discussed. PATIENTS AND METHODS: The records of 16 cases (1 female, 15 males; mean age 58 years; range 30 to 83 years) with recurrent lower lip carcinoma admitted between March 2002 and September 2007 to Dr. Abdurrahman Yurtarslan Oncology Training and Research Hospital, Ear, Nose and Throat Department were retrospectively reviewed. RESULTS: Fourteen patients had been treated in other institutions, while two had been treated in our center. Four of the patients had recurrence in the lip, four patients had recurrence only in the neck, and the remaining eight patients had both lip and neck recurrence. Ten patients received modified radical or radical neck dissection because of their palpable lymphadenopathies, three patients received supraomohyoid neck dissection due to non palpable lymphadenopathies, and the remaining three patients did not have neck dissection because of co-morbid diseases. Seven patients (43%) died in the first postoperative year because of lower lip carcinomas and three patients died because of other reasons. Six patients survived for the first two years without any evidence of disease. CONCLUSION: Patient survival will be affected by the applied treatment. For patients with primary lower lip cancers, otolaryngologists experienced in oncology must plan surgery rather than local treatments. In case of locoregional recurrence, immediate treatment should be planned.

Voice and Quality-of-Life Outcomes of Diode Laser for Tis-T1a Glottic Cancer.

The aim of this prospective study was to analyze the voice and quality-of-life outcomes of microscopic diode laser surgery (MDLS). The study was conducted on a series of 46 patients with Tis-T1a glottic carcinoma treated with microscopic endolaryngeal diode laser surgery. Patients were asked to complete the Voice Handicap Index and quality-of-life questionnaires of the European Organization for Research and Treatment of Cancer. When comparing the pre- and postoperative scores, there were significant difference on the physical scores (P = .014) of the patients who underwent type III cordectomy and functional (P = .022), emotional (P = .002), and overall scores (P = .005) of the patients who underwent type IV cordectomy, in the direction of better quality of voice after MDLS. The postoperative functional, physical, emotional, and overall scores of groups were significantly increased with the extension of resection.

[Eagle's syndrome: a case presentation]. / Eagle sendromu: olgu sunumu.

Eagle's syndrome occurs when an elongated styloid process or calcified stylohyoid ligament causes recurrent throat pain or foreign body sensation, dysphagia. Diagnosis can usually be made on physical examination by digital palpation of the styloid process in the tonsiller fossa. Three-dimensional computed tomography can utilized for supporting diagnosis. The treatment of Eagle's syndrome is primarily surgical. The styloid process can be shortened through an intraoral oe external approach. We report a 46- year-old woman with the seymptomatology of Eafle's syndrome and literature review.

[Lipid peroxidation and antioxidant levels in patients with laryngeal carcinoma]. / Larenks karsinomlu hastalarda lipid peroksidasyonu ve antioksidan seviyeleri.

OBJECTIVES: Reactive oxygen species (ROS) play an important role in the pathogenesis of cancer. The aim of this study was to investigate the extent of lipid peroxidation and ROS in laryngeal cancer tissues. PATIENTS AND METHODS: We determined glutathione (GSH) and malondialdehyde (MDA) activities as markers of lipid peroxidation in laryngeal tumor specimens and tumor-free adjacent tissues of 30 patients with squamous cell carcinoma. RESULTS: Compared to the tumor-free specimens, the level of GSH was significantly low (p<0.001) whereas MDA, a lipid peroxidation product, showed a significant increase (p<0.01) in cancer tissues. No significant differences were found in MDA and GSH levels between patients with early (n=14) and advanced (n=16) tumor stages (p>0.05). CONCLUSION: Decreased antioxidant capacity of laryngeal cancer tissues results in elevation of free oxygen radicals and increased lipid peroxidation. Free radical metabolism may be involved in the pathogenesis of laryngeal cancers.

Swallowing and Aspiration: How Much Is Affected by the Number of Arytenoid Cartilages Remaining After Supracricoid Partial Laryngectomy?

OBJECTIVES: The aim of this study was to compare the effect of the presence of one or two arytenoids on early/late period swallowing-aspiration functions. METHODS: Supracricoid partial laryngectomy (SCPL) with the diagnosis of laryngeal cancer between 2012 and 2014 were retrospectively evaluated. The patients were categorized into two groups as follows: group I, patients who underwent SCPL with one arytenoid cartilage and group II, patients who underwent SCPL with two arytenoid cartilages. The time of decannulation and oral feeding onset, and swallowing-aspiration functions were evaluated and compared in the early nutritional period, first, and third months. RESULTS: There was no significant correlation between decannulation time and swallowing-aspiration. The aspiration rates in group I and group II were similar and there was no significant difference in oral feeding onset and aspiration grades in the first and third months between both groups. CONCLUSION: We found similar oncological and functional outcomes in SCPL which protected one or two arytenoid cartilages. Therefore we suggest to be performed one arytenoid cartilage SCPL in selected patients who was advance stage and tumor volume over with larynx cancer.

Coexistence of laryngeal squamous cell carcinoma and non-Hodgkin's lymphoma with nasopharyngeal involvement.

Laryngeal squamous cell carcinoma (SCC) is one of the most frequent malignancies in the head and neck region. The risk of multiple malignancies is reported as 2-11 per cent and most of the second primaries are SCCs. Lymphogenic tumours as second primaries are extremely rare. In this paper, we report a case of laryngeal SCC with synchronous non-Hodgkin's lymphoma and review the literature on the clinical and histopathological aspects of these malignancies.

A Rare Entity: Adult Asymptomatic Giant Vallecular Cyst.

Background. Cysts in the larynx are rare and generally asymptomatic. However, large cysts in adults can be symptomatic. If they are symptomatic, they typically present with respiratory and feeding difficulties. They are usually benign in terms of pathology. Several surgical techniques may be used for treatment. Case Report. A 56-year-old man presented to our clinic with hoarseness. Routine laryngeal examination revealed a giant mass and the larynx could not be visualized. At magnetic resonance imaging (MRI), a cystic mass originating from the vallecula was detected. There was no pathology at the glottic level. We planned tracheotomy for the airway and endoscopic surgery for excision. The mass was excised using CO2 laser and was reported as benign. Conclusion. An asymptomatic vallecular cyst may cause difficult intubation in any operation. It may also cause respiratory or other complications. Airway management should be led by an ear, nose, and throat surgeon, since tracheotomy may be required. Endoscopic excision with CO2 laser is a good choice for treatment in elective cases. In this report, we discuss the diagnosis and treatment of a patient with an asymptomatic giant vallecular cyst.

Differential ototoxicities induced by lead acetate and tetraethyl lead.

Lead poisoning disrupts many biological structures and functions, including those of the auditory system. This study examined the ototoxic effects of lead acetate (LA) and tetraethyl lead (TEL) of equal lead content on cochlear function and the ability of alpha-phenyl-tert-butyl-nitrone (PBN) to attenuate such effects. Baseline 1.0 microV cochlear microphonic (CM) and compound action potential (CAP) responses were recorded and animals administered either PBN (100 mg/kg, i.p.) or an equal volume of 0.9% saline, followed by an i.p. injection of LA (50 mg/kg) in an ethanol vehicle, TEL (42.7 mg/kg) in a corn oil vehicle, corn oil or ethanol vehicle alone. Two hours after administration, post-exposure CM and CAP responses were recorded. CAP threshold shifts in the saline-LA group were elevated by 5-10 dB at mid to high frequencies relative to controls (20-24 kHz, P<0.05). Mean CAP threshold shifts in the saline-TEL were significantly greater than those of both control groups at all tested frequencies except 2 kHz (P<0.001). However, threshold shifts in the group receiving PBN prior to TEL were significantly smaller than shifts in the group receiving saline prior to TEL (P<0.01). These data suggest that TEL is more ototoxic than is LA and that free radicals partially mediate TEL-induced CAP disruption.
