Novel Multidisciplinary Salivary Gland Society (MSGS) Questionnaire: An International Consensus.

OBJECTIVES: First, establishment and validation of a novel questionnaire documenting the burden of xerostomia and sialadenitis symptoms, including quality of life. Second, to compare two versions regarding the answering scale (proposed developed answers Q3 vs. 0-10 visual analogue scale Q10) of our newly developed questionnaire, in order to evaluate their comprehension by patients and their reproducibility in time. STUDY DESIGN: The study is a systematic review regarding the evaluation of the existing questionnaire and a cohort study regarding the validation of our new MSGS questionnaire. MATERIALS AND METHODS: A Multidisciplinary Salivary Gland Society (MSGS) questionnaire consisting of 20 questions and two scoring systems was developed to quantify symptoms of dry mouth and sialadenitis. Validation of the questionnaire was carried out on 199 patients with salivary pathologies (digestive, nasal, or age-related xerostomia, post radiation therapy, post radioiodine therapy, Sjögren's syndrome, IgG4 disease, recurrent juvenile parotitis, stones, and strictures) and a control group of 66 healthy volunteers. The coherence of the questionnaire's items, its reliability to distinguish patients from healthy volunteers, its comparison with unstimulated sialometry, and the time to fill both versions were assessed. RESULTS: The novel MSGS questionnaire showed good internal coherence of the items, indicating its pertinence: the scale reliability coefficients amounted to a Cronbach's alpha of 0.92 for Q10 and 0.90 for Q3. The time to complete Q3 and Q10 amounted, respectively, to 5.23 min (±2.3 min) and 5.65 min (±2.64 min) for patients and to 3.94 min (±3.94 min) and 3.75 min (±2.11 min) for healthy volunteers. The difference between Q3 and Q10 was not significant. CONCLUSION: We present a novel self-administered questionnaire quantifying xerostomia and non-tumoral salivary gland pathologies. We recommend the use of the Q10 version, as its scale type is well known in the literature and it translation for international use will be more accurate. Laryngoscope, 132:322-331, 2022.

Step-by-Step Cadaver Dissection and Surgical Technique for Compartmental Tongue and Floor of Mouth Resection.

BACKGROUND: The aim of oral cancer surgery is tumor removal within clear margins of healthy tissue: the latter definition in the literature, however, may vary between 1 and 2 cm, and should be intended in the three dimensions, which further complicates its precise measurement. Moreover, the biological behavior of tongue and floor of mouth cancer can be unpredictable and often eludes the previously mentioned safe surgical margins concept due to the complexity of tongue anatomy, the intricated arrangements of its intrinsic and extrinsic muscle fibers, and the presence of rich neurovascular and lymphatic networks within it. These structures may act as specific pathways of loco-regional tumor spread, allowing the neoplasm to escape beyond its visible macroscopic boundaries. Based on this concept, in the past two decades, compartmental surgery (CS) for treatment of oral tongue and floor of mouth cancer was proposed as an alternative to more traditional transoral resections. METHODS: The authors performed three anatomical dissections on fresh-frozen cadaver heads that were injected with red and blue-stained silicon. All procedures were documented by photographs taken with a professional reflex digital camera. RESULTS: One of these step-by-step cadaver dissections is herein reported, detailing the pivotal points of CS with the aim to share this procedure at benefit of the youngest surgeons. CONCLUSIONS: We herein present the CS step-by-step technique to highlight its potential in improving loco-regional control by checking all possible routes of tumor spread. Correct identification of the anatomical space between tumor and nodes (T-N tract), spatial relationships of extrinsic tongue muscles, as well as neurovascular bundles of the floor of mouth, are depicted to improve knowledge of this complex anatomical area.

Compartmental Surgery for Oral Tongue Cancer: Objective and Subjective Functional Evaluation.

OBJECTIVE: To assess functional outcomes in patients treated by compartmental tongue surgery (CTS) and reconstruction for advanced oral tongue/floor-of-mouth cancer. STUDY DESIGN: Retrospective case series. METHODS: A retrospective cohort of patients (n = 48) treated by CTS and free flap reconstruction was prospectively evaluated concerning postoperative functional outcomes at different time points (6 months and 1 year). Swallowing was studied by videonasal endoscopic evaluation (VEES) and videofluoroscopy (VFS), testing various food consistencies and grading the results with the Donzelli scale. Speech articulation, lingual strength, and endurance were studied by phone call and Iowa Oral Performance Instrument (IOPI). Subjective tests (EORTC H&N35 and UWQOL) were administered. RESULTS: After 1 year, VEES showed a Donzelli scale of 67% level 1, 23% level 2, and 10% level 3. Vallecular pouch was present in 81% of patients. VFS showed levels 1, 2, and 3 in 42%, 25%, and 33%, respectively, with liquids (L); 48%, 19%, and 33%, with semi-liquids (SL); and 54%, 33%, and 13%, with semi-solids (SS). Vallecular pouch residue was present in 69% with L, 73% with SL, and 87% with SS. The mean number of words recognized at phone call was 56 of 75 (range, 27-74). IOPI showed a mean tongue strength of 19.2 kPa (range, 0-40), and a mean endurance of 16.2 seconds (range, 0-60). CONCLUSION: CTS does not significantly affect speech. Sub-clinical food aspiration and vallecular pouch are present in a significant proportion of patients, especially when adjuvant treatments are administered. Residual tongue strength is not affected when proper reconstruction is performed. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E176-E183, 2021.

Transoral excision of a retropharyngeal lymph node under rigid endoscopic control.

Different traditional surgical approaches, such as transcervical, transparotid, and mandible-splitting procedures, have been described to expose the retropharyngeal space. The introduction of the transoral approach, in selected patients, provided a direct and adequate access to the retropharyngeal space, permitting a feasible and minimally invasive procedure to remove retropharyngeal lymph nodes. We report a case of a transoral video-assisted approach for the excision of a retropharyngeal lymph node in a young man who had previously been treated at another institution by surgery and radiotherapy for oral tongue cancer. The endoscopic magnification allowed us to perform a meticulous and relatively bloodless dissection of the lesion from the surrounding tissues with a clear identification of the anatomic structures, and therefore may represent a valid alternative to the use of a microscope or loupes to enhance vision. A clear understanding of the anatomy of the retropharyngeal space and a high degree of surgical expertise are required to perform a safe dissection of the lesion.

Incidence of palmar-plantar erythrodysesthesia in pretreated and unpretreated patients receiving pegylated liposomal doxorubicin.

AIMS AND BACKGROUND: Association between pegylated liposomal doxorubicin-based regimens and palmar-plantar erythrodysesthesia have just been emphasized, whereas the relationship between previous treatment and palmar-plantar erythrodysesthesia is still a matter of discussion. We evaluate the relationship between previous chemotherapy treatments and the development of palmar-plantar erythrodysesthesia in patients receiving pegylated liposomal doxorubicin-based regimens. METHODS: Between January 2005 and November 2006, 92 patients received regimens including pegylated liposomal doxorubicin. Patients were divided into three groups based on pegylated liposomal doxorubicin dosing interval length, different dose chosen, and previous chemotherapy. RESULTS: Among pretreated patients receiving regimens including 30 mg/m2 of pegylated liposomal doxorubicin repeated every three weeks, the incidence of palmar-plantar erythrodysesthesia was not significantly higher than in unpretreated patients receiving the same weekly schedule (P = 0.4). There was no difference in the incidence of palmar-plantar erythrodysesthesia between pretreated patients with regimens including 30 mg/m2 of pegylated liposomal doxorubicin every three weeks and pretreated patients receiving 20 mg/m2 of pegylated liposomal doxorubicin every two weeks (P = 0.8). The prevalence of palmar-plantar erythrodysesthesia observed in the unpretreated group exposed to 30 mg/m2 every three weeks was comparable to that of the pretreated group receiving 20 mg/m2 biweekly (P = 0.3). However, excluding all the patients who developed grade 1 palmar-plantar erythrodysesthesia, the incidence of grade 2 and 3 palmar-plantar erythrodysesthesia observed in pretreated patients receiving regimens including 20 mg/m2 of pegylated liposomal doxorubicin biweekly was significantly higher than in unpretreated patients receiving 30 mg/m2 of pegylated liposomal doxorubicin every three weeks (P = 0.001). CONCLUSIONS: Our findings indicate that the pretreatment is not involved in the increased incidence of any grade palmar-plantar erythrodysesthesia. On the contrary, the study could suggest that the type of previous treatment may be an important factor in the development of more severe forms of palmar-plantar erythrodysesthesia.

Fungus ball of the paranasal sinuses: experience in 160 patients treated with endoscopic surgery.

OBJECTIVES/HYPOTHESIS: Herein we present our experience in the management of fungus ball (FB) of the paranasal sinuses. Preoperative imaging strategy and findings, surgical technique, and pathologic and microbiologic results are discussed. STUDY DESIGN: Retrospective chart review of patients with FB of the paranasal sinuses who underwent endoscopic surgery at the Department of Otorhinolaryngology of the University of Brescia, Italy. METHODS: From January 1990 to December 2006, 160 patients with sinonasal fungus ball were treated with a purely endoscopic approach. All patients underwent preoperative computed tomography (CT) and/or magnetic resonance (MR) imaging; an endo-oral dental x-ray or orthopantomography and odontological evaluation were also performed in patients with maxillary sinus localization. All removed material was sent for pathologic and microbiologic evaluation. All patients were prospectively followed with endoscopic control every 2 months during the first postoperative year and subsequently every 6 months. RESULTS: The patient cohort included 118 females and 42 males, with an age from 19 to 85 years (mean, 52.7 years). FB was located in the maxillary sinus in 135 (84.4%) patients; in two cases both sinuses were affected. Sphenoid and ethmoid involvement was observed in 23 (14.4%) and 1 (0.6%) patients, respectively. Simultaneous ethmoid and sphenoid involvement was found in one (0.6%) case. In all patients complete removal of fungal debris was obtained through wide sinusotomy. No recurrence was observed. CONCLUSIONS: Endoscopic surgery is a safe and effective treatment for paranasal sinuses FB. A proper imaging study by MR and/or CT can address diagnosis, which is based upon detection of fungal hyphae at histology.
