Role of the neck dissection in early-stage lower lip cancers.

Background: In early-stage lip cancer, spread to cervical lymph nodes is extremely rare. Elective neck treatment options include suprahyoid or supraomohyoid neck dissection, sentinel lymph node biopsy, or close follow-up. Aim: In this study, our aim was to investigate the effect of elective surgery on survival in patients operated for early-stage lip cancer. Methods: Patients who underwent surgical treatment for lower lip squamous cell carcinoma between 2005 and 2020 were retrospectively analyzed. Age, gender, neck dissection status (yes/no), clinical and pathological T stage of the tumor, grade, and perineural invasion were recorded and 3-year and 5-year overall (OS) and disease-free survival (DFS) rates were estimated. Results: Thirty patients were included: 20 patients had pT1 and 10 patients had pT2 tumors. Neck dissection was performed in 13 patients. The 5-year OS rate was 90.9% and 87.8% with and without dissection, respectively. Neck dissection did not appear to affect OS (P = 0.534) in these patients. The 5-year DFS rate was 96.4% in the overall group, while it was 91.7% and 100% in patients who did or did not undergo neck dissection, respectively (P = 0.756). Discussion: Patients with or without neck dissection did not differ significantly in terms of OS and DFS. Watchful waiting with regular ultrasound imaging of the neck in patients with T1 and T2 lip tumors may be an appropriate therapeutic option.

Correlation between clinical findings and eosinophil/neutrophil ratio in patients with nasal polyps.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a frequent disease which can be classified as eosinophilic or neutrophilic based on dominant inflammatory cell type at tissue. The aim of this study was to evaluate the clinical relevance of classifying nasal polyps as eosinophilic or neutrophilic on treatment outcomes. The study was conducted with 40 patients who underwent either surgical or medical treatment with the diagnosis of CRSwNP. The patients were classified into two groups for further assessment up to eosinophil intensity at polyp tissue. All patients were examined by nasal endoscopy and paranasal computed tomography (CT). Before treatment, subjective symptom score, nasal endoscopy score, and CT score were measured. Subsequently, they were reevaluated by similar diagnostic tests after either medical or surgical treatment at sixth month. The preoperative subjective symptom score, endoscopy score, and paranasal CT score were compared between chronic rhinosinusitis (CRS) with eosinophilic nasal polyps (E-NP) (CRSwE-NP) group and CRS with neutrophilic nasal polyps group and there was no difference between the two groups (p = 0.369, p = 0.310 and p = 0.494 respectively). Although after treatment in both groups symptom score and endoscopy score were significantly improved but not the CT score, we found no difference in between the groups at sixth month. In most of the previous studies, patients with CRSwE-NP were assumed to have poor prognosis and high recurrence rate despite surgical or medical treatment. However, we did not find any association between eosinophilic or neutrophilic nature of nasal polyp tissue and disease severity.

Topographic distribution of laryngeal cancer.

The anatomic distribution of laryngeal cancer (LC) among the compartments of the larynx shows geographic variations. In the U.S., glottic cancers are more frequently seen, whereas most cases in the Mediterranean countries are supraglottic. We reviewed the anatomic sites of involvement in patients with laryngeal cancer seen in our clinic and at eight other university clinics between 1990 and 1994. The majority of cases were supraglottic cancers, accounting for 60% of all laryngeal tumors.

Regional epidemiological features of lip, oral cavity, and oropharyngeal cancer.

Lip, oral cavity, and oropharyngeal cancer are among the most common forms of the disease in the world. These types of cancer display significant geographic, ethnic, and socioeconomic variations. We examined the cases of cancer of the lip, oral cavity, and oropharynx diagnosed in the Department of Otolaryngology at the University of Uludag School of Medicine during the last 5 years, July 1990 to June 1995, and recorded the epidemiological features of these tumors. The Department of Otolaryngology treated a total of 26,225 in- and outpatients during the 5-year period. 320 of these patients (1.2%) were seen for head and neck cancer. 42 of the 320 patients (13.1%) were diagnosed with cancer of the lip, oral cavity, and oropharrynx. After the larynx, this was the second most frequent location of malignant head and neck tumors. We discovered the following epidemiological and pathological features: (1) The incident rate was highest in patients between 41 and 60 years of age. (2) 70% of the patients were male, and 76% of them had a history of tobacco/alcohol use. (3) Occupation had no apparent relevance (four of the patients were farmers). (4) Approximately one third of the patients had undergone medical therapy prior to diagnosis. (5) One third of the patients had initially seen a dentist for treatment, and approximately half had poor dental and oral hygiene. (6) The most frequent symptom was ulceration. (7) Histopathological examination revealed squamous cell carcinoma in 88% of the cases. (8) The cancer was localized to the lip in 31% of cases, oral cavity, 50%, and oropharynx, 19%. (9) Almost half of the cancer cases were diagnosed in advanced stage (stages III and IV).

Factors affecting wound infection rates in head and neck surgery.

PURPOSE: This study was planned with 2 goals in mind: to evaluate the efficacy of prolonged and 1-day antibiotic regimens for prophylaxis and to evaluate the effect of various factors such as neck dissection, localization and stage of tumor, type of laryngectomy, and history of prior radiotherapy, tracheotomy, and diabetes mellitus on postoperative wound infection rates. METHODS AND MATERIAL: In this study, 408 head and neck procedures (201 clean and 207 clean-contaminated) performed at our institution were retrospectively reviewed. RESULTS: Prolonged and 1-day antibiotic regimens for both clean and clean-contaminated procedures were similar in efficacy (7% vs 3% for clean procedures [P = 0.165] and 30% vs 28% for clean-contaminated procedures [P = 0.777]). The wound infection rate was higher (13%) after clean radical neck dissections versus other clean procedures (1%) (P = 0.001). For clean-contaminated procedures, factors affecting postoperative wound infection rates were performance of bilateral neck dissections (P = 0.014), disease stage (P = 0.002), type of laryngectomy (P = 0.002), and history of prior tracheotomy (P = 0.006).

Quantitative analysis of the drainage after neck dissection.

The goals of this study are to determine the normal volume and lipid values of the drainage after neck dissection (ND) and to evaluate the changes of these values according to the type and side of the ND. Ninety-seven uncomplicated NDs involving zones I through IV were evaluated prospectively in this study. The most important result of the analysis of the drainage is that levels of triglyceride and cholesterol in the drainage were lower than serum levels in all but 1 case (P< 0.001). When matched for the type and side of the dissection, only mean total drainage volume was significantly higher in radical NDs than in selective NDs (P = 0.001). The normal volume and lipid values of neck drainage are reported in this study. Being aware of the changes in these values may help early diagnosis of some pathologic conditions.
